Textile people really do speak their own language. And besides the terms used in spinning, we also need to understand the terms fiber producers use. And then the dyers and weavers definitely have their own language.
If you think of terms that should be added (or definitions changed), please send me a note through TEXT-TEAM to email@example.com
Abaca: A hemp like fiber used for cordage grown in the Philippine Islands.
Abrasion Resistance: The ability if a fiber or fabric to withstand surface wear and rubbing.
Abrasion : The wearing away of fiber by rubbing away.
Absorbency : The ability of a fiber or fabric to absorb moisture.
Acetate : A manufactured fiber that uses cellulose refined from cotton and/or wood pulp. Characteristics: fast drying, wrinkle- and shrinkage-resistant, crisp or soft depending on end use, luxurious in appearance.
Acid Dye: A dye which is applied to protein fabric or fiber from an acid dye solutions. It can be used on nylon, wool and other animal protein fibers, silk, acrylic, polypropylene and blends. It is fairly colorfast to light and laundering.
Acrylic: A manufactured fiber made from long-chain synthetic polymers. Characteristics: wrinkle resistance; low moisture absorbency and quick-drying; provides warmth yet lightweight, soft and resilient.
Adjective Dye: A dye which requires the use of mordents. See natural dyes.
Air Jet Spinning: A spinning system in which yarn is made by wrapping fibers around a core stream of fibers with compressed air.
Air Permeability: The porosity, or the ease with which air passes through material. Air Permeability determines such factors as the wind resistance of sailcloth, the air resistance of parachute cloth, and the efficiency of various types of air filtration media. It is also a measure of warmness, or coolness of a fabric.
Akha Spindle: A lightweight, supported spindle.
Aklae: Norwegian low-warp tapestry technique. Wefts interlock between two warp ends.
Alpaca: Specialty hair fiber from the alpaca, a member of the South American llama family. It is softer, finer, more lustrous and stronger than sheep’s wool, but in relatively short supply. Fibers are prized for their strength, durability and beauty. Please see McColl’s Darkroom in Cyberspace for drawings showing a close-up of fiber.
Alum: Hydrated double-sulfate of alumina potassium. A commonly used mordant.
Albegal SET: Liquid dyeing assistant for Sabraset/Lanaset Dyes, used to obtain level colors.
Alternating Twist: A texturing procedure in which S and Z twist are alternately inserted in the yarn by means of a special heating apparatus.
Amercian Pima Cotton: A cross between Sea Island and Egyptian cotton. Grown in Arizona. Length averages 13/8″ to 15/8″.
Ammonia: An alkaline liquid used in natural dyeing.
Ammonium Sulfate: A mild acid-forming salt used with acid dyes. Used to insure levelness for light to medium shades.
Anti-chlor Concentrate: A sodium bisulfite compound used to neutralize residual chlorine when removing color with hypochlorite bleach.
Aniline Dyes: A class of synthetic, organic dyes originally obtained from aniline (coal tars),and were the first synthetic dyes. Today the term is used with reference to any synthetic organic dyes and pigments, in contrast to animal or vegetable coloring materials, and synthetic inorganic pigments. Aniline dyes are classified according to their degree of brightness or their light fastness. Also called “coal tar dyes.”
Animal Fibers: Protein-based hair, fur, and cocoon materials taken from animals. Typical animal fibers include, wool, mohair, llama, alpaca, cashmere, camel and vicuna and cocoon material (silk).
Angora: Downy soft, fluffy hair that is plucked or sheared from the angora rabbits. This is a slippery, flyaway fiber is usually blended with wool or other fibers to make it easier to spin and to reduce the cost.
Angora Goat: The goat that produces “mohair“
Anthrax: A highly dangerous, infectious disease cased by Bacillus anthracis. In humans, a form of this disease is commonly called “wool sorter’s disease”. It may be contracted, most likely through skin abrasion from handling fleeces from infected animals. More information about this disease may be found at the HealthScout’s site.
Apparel Wool: All wools that are manufactured into cloth for use as clothing.
Aramid Fiber: A manufactured fiber in which the fiber-forming material is a long chain synthetic polyamide having at least 85% of its amide linkages (-NH0CO-) attached directly to two aromatic rings.
Attenuation: In spinning, the fibers are pulled out of a distaff or from a ball of roving into a strand of the desired diameter.
Autoclave: An apparatus for the carrying out of certain finishing operations, such as pleating and heat setting, under pressure in a superheated steam atmosphere.
Axle : This is the metal shaft through the center of wheel, supporting it. There is usually a set screw that ‘locks’ it in place which (sadly) can be sheared off.
Backcross : The mating of a crossbred animal to one of the parental breeds.
Bactrian Camel: The Bactrian camel is the camel that camel hair comes from.
Bags : In the United States, the commercial wool growers have their fleeces loaded into large cloth bags for shipping to the wool mills. In Australia and New Zealand, the fleeces are packed into “bales” — which load better in the ship holds for export abroad.
Balanced: A plied yarn that doesn’t twist back on itself. If you hold ~10 inches of yarn by the ends, then slowly move your hands closer together until they are ~2 inches apart, a balanced yarn will drape itself into an elongated U. An over-spun yarn will ply back on itself.
Balanced Cloth: A term describing a woven fabric with the same size yarn and the same number of threads per inch in both the warp and the fill direction.
Bales: In countries where the fleece traditionally has been shipped, the fleeces are packed into bales — which load better in the ship holds for export abroad. Depending on the country, the bales weigh different amounts. Australian and New Zealand bales weigh 150 kg (330 lb), whereas South American bales weight approximately 1,000 lb (454 kg).
Cotton also is shipped in 500-pound bales.
Basic Dyes :A class of dyes, usually synthetic, that act as bases, and which are actually aniline dyes. Their color base is not water soluble but can be made so by converting the base into a salt. The basic dyes, while possessing great tinctorial strength and brightness, are not generally light-fast.
Basket Weave : A variation of the plain weave in which two or more threads weave alike in both warp and weft, joined in the regular order of the plain weave. Named for the basket-like pattern of the weave.
Bast Fibers : Fiber obtained from the stems of certain types of plants. These include flax, hemp, jute, ramie, milkweed, and nettles.
Batik: A traditional dyeing process in which portions of cloth are coated with wax and resist the dye.
Batt or Batting : Sheets or rolls of carded cotton or wool or other fiber or mixtures thereof which is used for woolen spinning or for stuffing, padding, quilting, and felting.
Bead Yarn : A yarn upon which is fastened either an actual bead or (commercially) a lump of hardened gelatine of a bead-like form.
Beam: A cylinder of wood or metal, usually with a circular flange on each end, on which warp yarns are wound for slashing, weaving and warp knitting.
Beaming: The operation of winding warp yarns onto a beam usually in preparation for slashing, weaving or warp knitting. This process is also called warping.
Beating –Up – The last operation of the loom in weaving, in which the last pick inserted in the fabric is “beat” into position against the preceding pick, usually by a “comb- like” device called a reed.
Belly Wool : The wool that grows on the belly of the sheep and occasionally extends up the side in irregular patches. It is usually an uneven, different grade from the body of the fleece. It is shorter and less desirable because of its poor lock formation, and it usually lacks the character of the body of the fleece.
Beetle : A large wooden mallet used to help soften cellulose fibers. Often used with linen and ramie.
Beetling : The process of striking woven linen or ramie fabric with rollers to flatten the fibers. This leaves you with a more lustrous fabric.
Belly Wool: The short, and often weaker, fiber from the sheep’s belly. It should be skirted off.
Bicomponent Yarns: Spun or filament yarns of two generic fibers or two variants of the same generic fiber.
Bi-directional Fabric: A fabric having reinforcing fibers in two directions, i.e., in the warp (machine) direction and filling (cross-machine) direction.
Binders : The individual hairs in a sheep’s fleece that run from one staple to another.
Binding Threads: Threads used to unite two or more ply into one firm (stable) structure.
Black Wool: Any wool containing non-white fibers. A fleece having only a few black fibers is rejected by a grader and goes into the black wool bag because there is no way of separating the few black fibers in the manufacturing processes. Black wool is usually run in lots that are to be dyed.
Black-top Wool: Wool containing a large amount of wool grease combined at the tip of the wool staples with dirt, usually from a Merino. This wool is usually fine in quality, of good character, and desirable in type, but the shrinkage is high.
Bleeding: Loss of color by a fabric or yarn when immersed in water, a solvent, or similar liquid medium, as a result of improper dying or the use of dyes of poor quality.
Blend: 1. A yarn obtained when two or more staple fibers are combined in a textile process for producing spun yarns. 2. A fabric that contains a blended yarn in both the warp and filling direction.
Blending: The combining of staple fibers of different physical characteristics to assure a uniform distribution of these fibers throughout the yarn.
Blocker: A frame for drying wool. A fine picture of one can be found at the CyberFiber site. This is a open frame that rests on two supports with a handle on one side. You wind the damp yarn under even tension across the frame — not trying to line anything up. Rather like winding a bobbin for weaving. After the yarn dries, you can usually slide the whole skein off of one end. Edward Worst’s book “How to Weave Linens” has directions for making a blocker. Sadly, this book is out of print.
Blocking : The process of drying a skein of wool under tension. This can be done by drying a skein on a blocker. More prosaically, it can done by winding around an upended-chair’s legs or by hanging a weight in the bottom of a skein. A #2 can of tomatoes is often used as you don’t get a sharp crease.
Blood or Blood Grade: This refers to the fineness of the wool, measured as low 1/4, 1/4, 3/8, and 1/2 blood. It reflects the amount of Merino blood in a breed. ‘More blood’ refers to a larger amount of Merino in a sheep which should produce a finer wool. Please see Wool Grades.
Blowout Factor: The rapidity with which an animal’s fiber diameter thickens with age. (A bad thing.)
Boculè: A compound yarn comprising a twisted core with an effect-yarn wrapped around so as to produce loops on the surface.
Body: A term applied to wool when the staple has a good “hand” (full and with bounce). It can also refer to the fullness of a fabric. This is a subjective quality and has to do with a lack of limpness and/or stiffness. A fabric is said to have a good body when it has a full, rich, and supple hand.
Boiled Wool: Thick, dense fabric that is heavily fulled to completely obscure its knitted construction.
Boiling Off : The operation of removing, by means of a hot, mildly alkaline liquid, the gum (seracin) which covers the raw silk fiber. Also called “de-gumming”.
Bold: I saw one definition that said, “A term applied well-grown wool of good character.” Can you have wool with a bad character, i.e., from a bad neighborhood? I suspect that this is another one of those nebulous terms that apply to the wool’s “hand“.
Botany Wools: Originally referred to merino wool shipped from Australia’s Botany Bay. It has become a generic term used to describe superlative wools and fine worsted sweaters.
Bradford Count or Bradford System
The British standard is based on the Bradford Spinning Count System. This originated in the 19th century and is based on the number of 560-yard worsted skeins that can be produced from one pound of clean wool. The clean wool is then thoroughly oiled which aids in producing a smooth, lustrous yarn for suiting. With this system the larger number will be a finer wool. Please see wool grades.
Braid: 1. A narrow textile band, often used as trimming or binding, formed by plaiting several strands of yarn. The fabric is formed by interlacing the yarns diagonally to the production axis of the material. 2. In aerospace textiles, a system of three or more yarns which are interlaced in such a way that no two yarns are twisted around each other. Biaxial Braid – Braided structure with two yarn systems running in one direction and the other in the opposite direction. Triaxial Braid -a braided structure with axial yarns running in the longitudinal direction.
Braid Angle: The acute angle measured from the axis of the fabric or rope to a braiding yarn.
Braid Wool: The coarsest of the U.S. grades of wool, according to the blood system of classification. It is a very coarse and lustrous wool. Please see wool grades.
Braided Fabric: A narrow fabric made by crossing a number of strands diagonally so that each strand passes alternately over or under one or more of the other strands.
Braiding: The interwinding of three or more strands to make a cord or narrow fabric.
Break: Weak at a certain point, but strong above and below the weak spot, as opposed to “tender“, which signifies a generally weak fiber. This can be caused by a sudden change in pasture, feed, illness, or lambing. Please see McColl’s Darkroom in Cyberspace for drawings showing a close-up of fiber. Please also see: “Testing the Wool”.
Break Factor: A measure of yarn strength calculated as: 1) the product of breaking strength times the indirect yarn number. 2) The product of breaking strength tomes the reciprocal of the direct yarn number.
Breaking: Also known as “scrutching“. In breaking, the flax plants that have been through the “retting” process pass through rollers or are beaten with a wooden blade to help ‘break’ the stronger parts without damaging the longer fibers.
Breaking Length: A measure of the breaking strength of a yarn. It is the calculated length of yarn which equals its breaking load and is equal to the tensile stress at rupture of the yarn.
Breaking Load: The maximum stress needed to rupture a fiber, yarn or fabric in a tension test.
Breaking Strength: 1. The maximum resultant internal force that resists rupture in a tension test. 2. The load (or Force) required to break or rupture a specimen in a tensile test made according to a specified standard procedure.
Breech or Britch Wool : Wool from the thigh and rear region of the sheep. It is the coarsest and poorest wool on the entire fleece. It is usually manure-encrusted and urine-stained fiber. It should be “skirted” and removed from a fleece for a hand spinner.
Breed Characteristics or Breed Type: Individual breeds have distinct characteristics. A Merino is very fine, shows a lot of crimp, and the fibers are very close. A Lincoln, is much coarser with low crimp.
Bright: Very white, almost reflective, wool relatively free of dirt and sand. Some breeds, like Cormo, are known for producing particularly bright fleeces.
Britch: This is the short, curly fibers found in the groin and belly area of sheep. It has a very different character from the rest of the fleece and should be skirted out. In a perfect world, spinners would never see this.
Brittle: Brittle refers to harsh, dry, ‘wire-like’ fiber; much like the split ends in hair.
Broadcloth: A fine, closely woven, lustrous cotton or cotton/poly blend made in plain weave with a fine rib in the weft. The filling yarn is heavier and has less twist than the warp. The cloth is usually mercerized, and has a soft, firm finish.
Brocade: Brocade is a jacquard weave with an embossed effect and contrasting surfaces. Can also be woven with synthetic or man-made fibers.
Broad Goods: Woven fabrics 18 inches or more in width.
Broken End: A broken, untied warp thread in a fabric. Broken ends can result from: slubs, knots, improper shuttle alignment, shuttle hitting the warp shed, excessive warp tension, faulty sizing, and rough reeds, heddles, dropwires and shuttles.
Broken Pick: A broken filling thread in a fabric. Broken Picks can result from: excessive shuttle tension, weak yarn, or filling coming in contact with a sharp surface.
Brushed Wool: Finished yarn or material that has been brushed to raise all loose fibers to the surface, i.e., the commercially-spun mohair yarn.
Buck Fleece: A fleece from a ram. The wool usually has a heave shrinkage due to excessive wool grease; thus wool of this type is not worth as much in the grease as a similar wool from ewes or wethers. Some buck fleeces have a distinctive odor that many find objectionable.
Bulk Grade: The largest percentage of grade in a lot of original-bagged wool.
Bulky: In wheels, a term used for a wheel with a wide orifice. This allows the creation of a thicker yarn suitable for blanket wefts.
Bump: A cylinder of coiled, prepared fibers ready for spinning. This is how commercially prepared fibers are delivered. Rather like if you had access to a really big ball winder and used it to wind the top you had just hand combed.
Burry Wool: Wool heavy in vegetable matter — including burs, leaves, seeds, and twigs, which requires special and expensive processing in removal.
Bursting Strength: The mechanical test done commercially on fibers to show how strong they are.
Cabled Yarn: Two or more plied yarns twisted together. One or more part of a cabled yarn can be a single. So if you took two 2-ply and plied them again, you would have a cabled yarn. It is important to remember that you reverse the twist for each step. So if you spun your singles Z, the 2-ply would be spun S, and the cabled yarn would be produced by plying Z. You will need to have extra twist in the singles and the first ply to produce a “balanced yarn“. Please check Mabel Ross’ book “Essentials of Yarn Design for Hand spinners” for detailed directions.
A 3-2 cable refers to three 2-ply.
Cabled Twist: A construction of thread, yarn, cord, or rope in which each successive twist is in the same direction opposite the preceding twists; i.e., an S/Z/S, or Z/S/Z construction.
Calender: A machine used in finishing to impart a variety of surface effects to fabrics. A calender essentially consists of two or more heavy rollers, sometimes heated, through which the fabric is passed under heavy pressure.
Calendering: A mechanical finishing process for fabrics used to produce special effects, such as high luster, glazing, moiré’, and embossed effects.
Camel’s Hair: Hair from the two-humped Bactrian camel, which is softer, lighter in weight and more fragile than wool. It provides warmth without weight, it never wrinkles and is water repellent.
Camelid: Any animal that comes from the camel family. Obviously camels, but also alpaca and llama.
Canary-stained Wool: A yellowish coloration in the wool which cannot be removed by ordinary scouring methods. May be caused by bacterial growth or urine staining.
Candle: This refers to the stiffened fat on an unwashed fleece. Not a pleasing condition for Hand spinners and often a condition when fleeces sit for years waiting to be spun.
Canvas: A general classification of strong, firm, closely woven fabrics usually made with cotton. A heavier, open weave comprised of plied yarns. Characteristics: very hard-wearing, generally water-resistant.
Fibers that have been carded which opens them up.
Carbon Fiber – A high-tensile fiber or whisker made by heating rayon or polyacrylonitrile fibers or petroleum residues to appropriate temperatures. Fibers may be 7 to 8 microns in diameter and more than 90% carbonized.
The process of treating wool with chemicals, usually acids, to destroy and remove the burrs without seriously damaging the wool. The usual chemical used is sulphuric acid. Wool so treated is known as carbonized wool.
Carders: Also known as hand carders (as opposed to “drum carders“). Some of the carders have curved backs, some straight backs. There is some belief that the reason why modern hand cards have the curved backs is because they were modeled after museum pieces. Unfortunately, the museum pieces were warped (curved). Early plans for carders show the straight backs.
Now, having said that, let me add that if you like using curved-back cards, you should do so. I have a pair of Ashford hand cards (with curved backs) that I just love. As much hand carding as I do, this isn’t a problem for me.
A more critical requirement is that your cards have offset handles. This will save wear-and-tear on your hands.
Carding: Carding is the process used to open out fleece so that it can be more evenly spun into a “woolen” yarn. The process by which the fibers are opened out into an even film. The etching, La Cardeuse (The Wool Carder), shows a woman carding with flat-backed carders. And, Celerina’s site has an animation showing hand carding.
Carding Cloth: The Woolly Designs site has a close-up of Carding Cloth. The material is used on hand cards, drum carders, and carding boards. The spacing of the tines causes it to be classified as ‘fine’ or ‘coarse’. Many manufacturers refer to their combs as ‘cotton cards’ or ‘wool cards’.
Carpet Beetle: The larvae of this beetle eats wool and other protein fibers. Various articles on fiber pests can be found here.
Carpet Wool: Coarse, harsh, strong wool that is more suitable for carpets than for fabrics. Very little of this type is produced in the U.S. Some of the choicer carpet wools are used to make tweeds or other rough sport clothing. Some breeds, like Karakul, are mainly used for rugs.
Cashgora: Fiber produced by crossing cashmere goats with angora goats.
Cashmere: Soft, silky fiber combed from the cashmere goat with a diameter of 18.5 microns or less. Cashmere has excellent insulating power, providing warmth without weight or bulk. It drapes beautifully, resists wrinkles, and sheds lint. Costly because of limited supply.
Castle Wheel: The flyer is usually mounted above the wheel, which means less floor space is used. A well-known example of this is the Castle Wheel at Alden Amos’ site.
Cellulose Fiber: Or cellulosic fiber. Fibers produced form the cell walls of plants, i.e., cotton, hemp, ramie.
Chaffy Wool: Wool containing a considerable amount of chaff — finely chopped straw.
Chambray: A general class of plain weave, usually cotton, made with a colored warp and white weft.
Character: The evenness, distinctiveness, and uniformity of crimp characteristic of their respective wool classes. A well-bred wool of ‘good character’ will usually show a pronounced crimp and distinct staple formation.
Charka: Charka (means wheel) was developed in India by Ghandi in early 1920’s so the people of India could spin cotton thread and not be dependent on foreign materials. A wonderful description of the ‘Khadi’ or ‘Swadeshi’ movement can be found in “A philosophy… handspun” by G. Janani at the Hindu.com site.
The book-size Charka is a mobile, self-contained charka. Charkas are designed for spinning fine fibers such as cotton, silk, angora, and cashmere, etc.
Charmeuse: Charmeuse is a satin weave silk with a crepe back sometimes called crepe-backed satin.
Cheeses: Cheeses refer to the spirals of pencil roving produced on the large mechanized carders. The fibers can be knit as is (the original Lopi®) or can be spun up.
China Grass: An alternative name for ramie, a bast fiber.
Citric Acid Crystals: Substitute for Acetic Acid 56%. Use 1 teaspoon to replace 1 teaspoon Acetic Acid 56%.
Merino sheep produce the best wool which is relatively short, but the fiber is strong, fine, and elastic and has good working properties. Merino fiber has the greatest amount of crimp of all wool fibers and has a maximum number of “scales“: two factors which contribute to its superior warmth and spinning properties. These sheep produce class one wool.
Class-two wools are not quite as good as the Merino wool, but this variety is nevertheless a very good quality wool. It is 50-200 mm in length, has a large number of “scales“, and has good working properties. This class of sheep originated in England, Scotland, Ireland and Wales.
Class-three Wool: These fibres are about 100-455 mm long, are coarser, and have fewer “scales” and less crimp than Merino and Class-two wools. As a result, they are smoother, and therefore, they have more lustre. These wools are less elastic and resilient. They are nevertheless of good quality to be used for clothing. This class of sheep originated in the United Kingdom.
Class-four Wool: These fibres are from 25-400 mm long, are coarse and hair like, have relatively few “scales” and little crimp, and therefore, more smoother and more lustrous. This wool is less desirable, with the least elasticity and strength.
Classification by Fleece: Wool shorn from young lambs differs in quality from that of older sheep. Also, fleeces differ according to whether they come from live or dead sheep, which necessitates standards for the classification of fleeces.
Clean Content: The amount of clean, scoured wool remaining after removal of all vegetable and other foreign material.
Clean Wool: Usually refers to scoured wool but occasionally it describes grease wool that has a minimum amount of vegetable matter.
Clear Finishing: Usually, worsteds are not brushed, but closely sheared to give the fabric a clean face and crisp feel. This is called clear finishing. See also “unfinished worsteds.
Clip: With angora goats, refers to the amount of hair removed from a single animal.
Cloth: A generic term embracing all textile fabrics and felts. Cloth may be formed out of any textile fiber, wire, or material.
Clock Reel :A device for winding hanks of yarn. Some come with various kinds of counters. An image of a clock reel can be found at the Illinois State Museum site.
Clothes Moth: The larvae of this moth eats wool and other protein fibers. Various articles on fiber pests can be found here.
Clothing Wool: (Industry Term) Wool under 1.5 in. in length and distinguished from combing wools by their shorter length. Principal properties include softness, crimpiness, and felting ability; see also “carding wool“.
Cloud Yarn: A term given to yarns of irregular twist obtained by alternately holding one of the component threads while the other, being delivered quickly, is twisted around it, and then reversing the position of the two threads; thus producing alternate clouds of the two colors.
Cloudy Wool: Wool that is off-color. It may be due to wool becoming wet while poorly stored in a pile.
Cloth: A generic term embracing all textile fabrics and felts. Cloth may be formed out of any textile fiber, wire, or material.
Coarse Wool: Wool that has a Blood grade of 1/4 or Common OR a numerical count grade of 44’s, 45’s, or 48’s, OR a micron count above 31. Coarse wool may have as few as 1 to 5 crimps per inch.
Coated Fabric: A fabric to which a substance such as lacquer, plastic, resin, rubber, or varnish has been applied in firmly adhering layers to provide certain properties, such as water impermeability.
Coated Fleeces: Some wool producers coat their fleeces that cut down on the amount of vegetable matter and weathering. Some images, from Gleason’s Fine Woolies, show coated sheep.
Coating: The application of a semi-liquid material such as rubber, polyvinyl chloride, or polyurethane to one or both sides of the textile material. Once the coating has dried (cured) it forms a bond with the fabric.
Collapse Yarn: Collapse yarn is (usually) an over spun single, dried under tension (see “blocking“) that is then knit or woven. When the item is moistened, the yarn returns to its original elastic state. See “balanced yarn“.
Color: The actual color of the wool. In industry a bright white to cream is most desirable; canary stains, brown or black stains are undesirable.
Color Abrasion: Color changes in localized areas of a garment resulting from differential wear.
Color Defect: Any color that is not removable in wool scouring, due to urine stain, dung stain, canary yellow stain, or black fibers.
Colorfastness: resistance to fading, i.e., the ability of a dye to retain its color when the dyed, or printed textile material is exposed to conditions or agents such as light, perspiration, atmospheric gases or washing that can remove of destroy color.
Combed fibers: Fibers that have combed. This process removes the short fibers. When drawn off, the fiber is called “top“.
Combing: An operation in the worsted system of fiber preparation that removes the short fibers (see “noil“, “second cuts“) and foreign impurities. The long fibers are straightened and laid parallel. See also “wool combs” and “worsted preparation“.
Combing, Dry: The preparing and combing of wool to which no oil has been added.
Combing in Oil: The preparing and combing of wool to which oil has been added to facilitate the manipulation of the fibers.
Combing Wool: Wools having sufficient length and strength to comb. According to industry standards, the length of fibers for strictly fine combing must be over 2.75 in., with an increase in length as the wool becomes coarser.
Common: One of the U.S. Grades of wool. It is next to the coarsest grade, and derives its name because it presumably comes from sheep of common ancestry.
Complements: These are colors that are opposite one another on the hue circle.
Composite : 1. An article or substance of two or more constituents, generally, with reinforcing elements dispersed in a matrix or continuous phase. 2. Hard or soft constructions in which the fibers themselves are consolidated to form structures rather then being formed into yarns.
Condition: In grease wool, the amount of yolk and foreign impurities it contains A fleece having a “heavy condition” would have a large amount of shrinkage.
Conditioning: A process of allowing textile materials to reach equilibrium with the surrounding atmosphere.
Cone: A conical package of yarn, usually wound on a disposable paper core.
Coning: The transfer of yarn from skeins or bobbins or other types of packages to cones.
Converter: An individual or organization that buys greige fabrics and sells them as a finished product to cutters, wholesalers, retailers, and others. The converter arranges for the finishing of the fabric.
Consistency: The uniform distribution of all the fiber characteristics within each lock and throughout the entire fleece.
Copp: This refers to the cone of fibers that builds up on a spindle.
Corduroy: A strong, durable fabric with cotton ground and vertical cut-pile stripes (wales) formed by an extra system of filling yarns. The foundation of the fabric can be either a plain or twill weave.
Core Spinning: The process of making a core-spun yarn. It consists of feeding the core yarn into the front delivery roll of the spinning frame and of covering the core yarn with a sheath of fibers during the spinning operation.
Core-Spun Yarn: A yarn made by twisting fibers around a filament or a previously spun yarn, thus concealing the core.
Core-testing: The coring of bales or bags of wool to determine the clean content (or “condition“) and yield.
Core Yarn: A yarn made by winding one yarn around another to give the appearance of a yarn made solely of the outer yarn.
Cortical Cells: The spindle shaped cells forming the inside structure of a fiber.
Cotted: A fleece that contains fibers that are matted (or “felted“) together.
Cotton: A cellulose fiber collected from the perennial shrub from the genus Gossypium; predominantly G. hirsutum (upland or long-staple cotton), but also some G. barbadense (Pima or extra-long-staple cotton). A vegetable fiber consisting of unicellular hairs attached to the seed of the cotton plant. Most cotton is colored a light to dark cream, and its chemical composition is almost pure cellulose. Colored cottons in shades of tan, greens, blue, and rust are also less commonly available. A distinct feature of the mature fiber is its spirality or twist. For more information on cotton, you might want to look at: “Queen Cotton” by Susan Druding from the Textile Arts Forum.
Cotton Count: The cotton count expresses the number of hanks required to make a pound of yarn. A hank of cotton is equal to 840 yards. So 1 cc = 840 yards of cotton, the coarsest cotton yarn. A 3 cc yarn would then be one third as course and would be expressed as 3/1 cc show that it is a single strand. Likewise plies are designated by two numbers separated by a slash such as 4/2 cc. This equals 3360 yards (4 x 840) of two-ply yarn. This yields 1680 yards of yarn per pound (3360/2). An 8/4 cc yarns would yield the same number of yards per pound, but would be a 4 plies of finer yarn. So a Number 8 four-ply yarn is the same diameter as a Number 4 two ply yarn.
Cotty Wool: Wool that has matted or felted on the sheep’s back. Caused by insufficient wool grease being produced by the sheep, usually due to breeding, injury, or sickness. This type of defective wool is more common in the medium to coarse wools. The fibers cannot be separated without excessive breakage in manufacturing.
Count: The number given to a yarn of any material, usually indicating the number of hanks per pound of that yarn. May also refer to the fineness to which a fleece may be spun. There are at least three definitions. In raw wool, a number used to indicate fineness, see “micron count“. In worsted yarn, the number of 560-yard skeins weighing one pound (Bradford method). In woolen yarn, the number of 256-yard skeins weighing one pound (Yorkshire method).
Crabbing: A term used in the textile industry. Crabbing sets the cloth and yarn twist by rotating the fabric over cylinders through a hot-water bath, or through a series of progressively hotter baths, followed by a cold-water bath. Crabbing is done to stabilize the fabric before dyeing and finishing and is necessary only for worsted fabrics.
Crease-Resistant: This refers to the ability of a fabric to resist creasing. Wool is considered to be very crease resistant, while cotton is not. And don’t even get me started on linen!
Creel: 1. A framework arranged to hold slivers, roving or yarns so that many ends can be withdrawn smoothly and evenly without tangling.
Creeling : The mounting of supply packages in a creel to feed fiber to a process, i.e., beaming, warping or weaving.
Crepe: A general classification of fabric characterized by a broad range of crinkled or gained surface effects. Methods of making crepe include the use of hard twisted yarns, special chemical treatment, special weaves and embossing.
Crimp:1. The waviness of a fiber expressed as crimps per unit length. 2. The difference in distance between two points on an unstretched fiber and the same two points when the fiber is straightened under tension. 3. The difference in the distance between two points when the yarn has been removed from the fabric and straightened under specific tension expressed as a percentage of the distance between the two points as the yarn lies in the fabric.
Crimp Recovery: The ability of a yarn or fiber to return to its original crimped state after being released from a tensile force.
Crocking: The rubbing-off of dye from a fabric as a result of insufficient dye penetration of fixation, the use of improper dyes or dying methods or insufficient washing and treatment after the dying operation. Crocking can occur under either wet or dry conditions.
Croop :Silk, especially after immersion in a weak acid, when compressed and rubbed, gives out a peculiar rustling sound, which is known as ‘croop’.
Crocking : The transfer of dye stuff from one fabric to another item by friction. This usually happens when a fabric or yarn has been overdyed.
Crossbred or Cross Bred : Wool produced by crossing different breeds of sheep.
Curl Yarn: A type of yarn which presents curls or loops of various sizes all along its surface. It is usually produced as follows: Two threads, a thick and a thin are twisted together, the thin being held tightly and the thick thread slackly twisted around it. This two-fold yarn is then twisted in the reverse direction with another thin thread, this untwisting throwing up the thick thread as a loop, the two fine threads holding the loops firmly.
Cuticle: The outer layer of cells of a fiber which are hard, flattened and do not fit together evenly and whose tips point away from the fiber shaft forming serrated edges. These serrated edges cause the fibers to grip together during processing and manufacturing. See also “scales“.
Crossbred Wool: A sheep bred from two distinct breeds; also a classification for wool of medium fineness. In the U.S., wool obtained from sheep of long-wool x fine-wool breeding. Usually this wool grades at 3/8 or 1/2 blood. Please see Wool Grades.
Crutched Wool: Wool that has been clipped from rear end and udder area of ewes in the early spring to prevent collection of manure and fly strike.

Wool taken from the sheep that have died on the range or have been killed. Wool recovered from sheep that have been dead for some time is occasionally referred to as ‘merrin’. Wool taken from sheep that have died on the range or have been killed. Dead wool fiber is decidedly inferior in grade and is used in low-quality cloth.
A unit of weight indicating the fineness of yarns and equal to a yarn weighting one gram per each 10,000 meters. The abbreviation for this is “d’tex”.
Wool that contains excessive vegetable matter, such as burs, seeds, and straw, or which is kempy, cotty, tender, or otherwise faulty.
Any method that removes yolk, suint, and dirt from wool.

Fine, strictly combing wool, usually from Ohio and Pennsylvania. Delaine wool does not necessarily have to come from the Delaine-Merino; however, that breed is noted for this class of wool.
Wool that has some luster but not enough to be classed as luster wool. Wool of this type is produced by the Romney and similar breeds.
A unit of weight indicating the fineness of fiber filaments and yarns, both silk and synthetic, and equal to a yarn weighting one gram per each 9000 meters; used especially in indicating the fineness of women’s hosiery. The abbreviation for this is “d” or “D”.
A well-known basic cotton or blended fabric in a right- or left-hand woven twill. Generally, the warp is dyed blue with a weft.
An index of the number of wool fibers per unit of a sheep’s body. Fine-wool breeds show greater fleece density than the coarser wool breeds.
Wool that is dark or grayish in color and generally heavy in shrinkage. May be caused by excessive yolk, poor farming conditions, or parasites.
A class of aniline dyes, so called because they have such great affinity for cellulose fibers, i.e., cotton and linen. While both these and acid dyes are sodium salts of dye acids, direct dyes do not require the use of a mordant. Their shades are duller than those of either acid or basic dyes and they tend to have less tinctorial value than the basic dyes; however, they have the very important advantages of being much more lightfast than the basic dyes and possibly more so than acid dyes.
Direction of Twist
(S twist or Z twist) To determine twist, hold yarn in a vertical position and examine the angle of the spiral. The angle of the S twist will correspond to the center portion of the S. The angle of the Z twist will correspond to the center portion of the Z. When spinning, the wheel should rotate counter clockwise for an S twist and rotate clockwise for a Z twist.
The weathering that occurs on the ends of some locks. These may not completely wash out or evenly dye.
A staff with a cleft or formed-end for holding flax from which the fiber is drawn in spinning. May be attached to a spinning wheel. The Monastic Heritage Museum shows a wheel-mounted distaff on a wheel from the 1800’s.
The small tool that is used to help form and even top in wool combing. Traditionally a diz was made out of carved horn. You can also make (or buy) very nice ones out of wood. A cheap, none-classy alternative is to trim a piece of plastic and punch or drill a hole in the middle of it. I’ve seen this done with the bottom corners of a plastic milk jug or a crescent cut from a section of PVC pipe. As always, if it involves worsted spinning, please see “Hand Woolcombing and Spinning” by Peter Teal.
A general term for a fabric woven on a special dobby loom, which allows the weaving of small, geometric figures. A dobby weave can often be distinguished from a plain weave by the patterns are beyond the range of simple looms.

A silk yarn reeled from two or more entangled cocoons and producing a coarse yarn Generally used in fabrics such as shantung or pongee. See “Reeled Silk“.
This is one of the two terms that Alden Amos uses when discussing plying. This refers to an “S-Twist“. Alden maintains that people get so hung up trying to remember whether an S-Twist is spun clockwise, that they lose track of process. It really doesn’t matter whether your singles are spun S or Z, you just need to ply them in the opposite direction.
Allso called ‘Hill Wool’. Wool of medium fineness produced by such breeds as the Southdown and the Shropshire. These sheep are distinguised by their fine and curly wool of short staple, which is especially adapted for making loose, rough, moss-like, felted, carded yars for the production of clothing. These wools are lofty and well suited for woolen. Much of the down wool runs 1/4 to 3/8 blood in quality. This can be a great wool for felting.

The process of drawing out the fibers so that twist can enter the fiber.
Ratio of wheel diameter to flyer whorl diameter (or bobbin whorl on a bobbin lead wheel). Governs how much twist you get in the yarn for each treadle.
To measure your wheel ratios, set up your wheel, tie a bright-colored piece of yarn to your flyer arm, and adjust the treadle until it is at the bottom of its movement. Slowly rotate the wheel, while counting the flyer revolutions until the treadle returns to it’s original point. The bright yarn tied to the flyer arm just makes it easier to count.
A spindle that hangs freely from the fiber source (as opposed to a supported spindle). Probably so named by people who haven’t added enough twist.
A rotating drum, covered with carding cloth, used to card fibers. An example hand-cranked drum carder can be viewed on the Ashford site.
This is a term for spinning flax and mainly is a way of differentiating it from ‘wet-spun flax’. In dry-spun flax, additional water is not added to the surface in spinning. It produces a hairier, less-attractive yarn.
A yarn or fiber surface lacking in lustre.
The second step in commercial wool processing (after sorting). The purpose is to remove as much dirt and sand as is possible before scouring.
There are many application classes of dyes, including acid dyes, disperse dyes, reactive dyes, and natural dyes. Dyes may be generally divided into natural and synthetic types. Natural dyes are obtained from berries, flowers, roots, bark and more. Synthetic dyes are chemical compounds.

The degree to which fibers will consolidate by felting.
The property of wool and some other fibers to interlock with each other to create felt. Felting is caused by the directional friction effect of scales on the fiber surfaces. The factors involved in felting are the fiber structure, the crimp of the fibers, the ease of deformation of the fiber and the fiber’s power of recovery from deformation.
The fundamental component used in making textile yarns and fabrics.

A hand tool that looks like a small hand card on a long handle. To use it, hold one end of a lock of wool in your left hand rested on your thigh and “flick” the tool up and down with your other hand catching the end of the fiber. This will open out the lock and make it easier to spin. It is recommended to wear a sturdy pair of jeans or place a leather pad on your left thigh.
A rotating device that adds twist to the slubbing or roving and winds the stock onto a spindle or bobbin in a uniform manner.

The device used to support full bobbins while plying. A fairly traditional design, involves two vertical posts that support the bobbins. Rather like a free-standing ladder. And example of this can be found on the LeClerc site. Another form, favored by Schacht, has the bobbins supported horizontally with the addition of a breaking cord to control the backspin. Now, Alden Amos favors a vertical support with the addition of leather washers to help slow down the backspin. At this time, there is no image available.

This is the length of yarn attached to the center core of a bobbin or shank of a spindle to aid in starting your yarn.
Also known as lees ties and lease ties. This is such an interesting term that pops in and out of textiles. I asked a longtime weaver which was correct. She said it wasn’t so much correct but where you learned to weave. The fact that a term used in measuring linen yarns is “lea” makes me think leas ties came from that direction. So what are they? They are the short threads tied around hanks of yarn to help keep them from tangling while being washed, dyed, and stored. They are also the short threads tied around a warp to allow you carry it from the warping board/mill to the loom. They serve the same process of keeping the threads in order. They are tied by running a thread at right angles to the warp/hank and interweaving through and coming back at opposite angles. Kind of a series of sideways figure 8’s.
A dye term referring to even color.
A fleece of wool midway between two grades in quality and length, which can be thrown into either grade.
Line fax is the long flax fiber that has been drawn off of the hackles. The finest preparation is often used for wet-spun linen, but line can also be dry spun.

The skin from a slaughtered sheep before the wool on it has been pulled or processed into a sheepskin.
A fleece with narrow staples or lock formation: indicates an open fleece that has less density and probably more vegetable matter. This type of lock formation is genetic and is passed on to offspring.
This is a rather terrifying tool used to help open out washed fleece prior to carding. Basically it is a crescent-shaped swing that rocks in a cradle. Between the base of the picker and the bottom of the swing, there are a series of nails that catch the fiber and open it out. This tool accomplishes much the same process as hand-picking your fiber — but much faster. As with any machinery, use with extreme caution.
The process of opening fiber and/or removing foreign matter.

A generic term for man-made fibers composed of regenerated cellulose derived from trees, cotton and woody plants. Characteristics: high absorbency, bright or dull luster, pleasant feel or hand, good draping qualities, ability to be dyed in brilliant colors and superior strength.
Wool that is reclaimed from new or old fabrics.
A long strand made of silk reeled from a number of cocoons and not twisted or spun. See “Doupioni“.
These are fibers created by modified natural fibers. The cellulose regenerated fibers include rayon and acetate. The protein-regenerated vegetable fibers include soybean (soylon), peanut (ardil), and corn (vicara). The protein-regenerated animal fibers include casein (aralac), gelatin, and albumin.
Off-grades thrown to one side by the wool grader; fleeces with excessive black fibers, kemp, dead fibers, vegetable matter, etc.
Scraps and clips of woven and felted fabrics made of previously used wool. These remnants are garnetted; that is, shredded back into a fibrous state and used in the manufacture of woolens.
The power of recovery to original shape and size after removal of the strain which caused the deformation. A fiber may possess this quality to spring back to its original state after being crushed or wrinkled. Resilience is sometimes referred to as memory.
A cationic dye fixing agent. Used on cotton fabrics to improve wet fastness of direct dyes and to color paper pulp. Is helpful as an after treatment for reactive dyes where washing facilities are not adequate for complete washout, though tends to lower light fastness qualities.
This is the process in flax production that weakens the fibers in the flax plant. Several retting methods are used:
- Dew or Grass Retting. Small bundles of the uprooted flax plants are left outdoors for 3-5 weeks.
- Pond Retting. Small bundles are left submerged for 4-8 days. Many books refer to an unpleasant stench as a side effect of this process.
- Stream Retting. Small bundles are anchored in a body of moving water. This is the quickest and the cleanest of the processes.
Apparently efforts are underway to perfect a process using enzymes to replicate the dew process. Retting occurs in flax fiber production after ‘rippling’ and before ‘breaking.
These are cleaned and shredded into fibers again, and then blended to make utility fabrics. See also “shoddy“.
The coarse comb used for removing seeds from flax fiber. The next step would be ‘hackling’. The preceeding step would be “scrutching“.
The process in flax production that removes the seed pods. The tool used is a ‘rippler’. After this step of flax fiber preparation, the fibers are ‘retted’.
Wool possessing a strong hand and bulky nature.
The cigar-shapped roll of carded fiber, losely rolled off of the hand cards, used as the fiber source when spinning woolen yarn.
The process where fleece is plucked off of Shetland sheep during the spring. This works with Shetland fleece as the sheep produce a weak spot earlier in the season. Sometimes called rooing.
The soft strand of carded fiber that has been twisted, attenuated, and freed of foreign matter preparatory to spinning.
A fleece that varies greatly in quality, lacks character, and carries a large percentage of britch wool and possibly kemp.
Three-legged ‘standard wheel’ featuring a side-by-side arrangement with the flyer to the left of the drive wheel.
Cuticle cells form a scale-like formation on the surface of the fiber, resembling shingles on a roof. These scales on the surface of the fiber open from base to tip, causing an interlocking or felting action when fibers are randomly mixed during processing. Please see McColl’s Darkroom in Cyberspace for drawings showing a close-up of fiber.
A single band drives the flyer. The bobbin has an adjustable friction band to slow it. When tension on the yarn is released, the bobbin rotations is stopped by the break band and the flyer winds the yarn onto the bobbin. Because this only involves one simple adjustment, many ‘beginner’ wheels use Scotch Tension. A well-known example of this would be the Ashford Traditional.
The process of washing or cleansing wool of grease, soil, and suint in a water/soap/alkali solution. When scouring is done commercially, a normal fleece goes through 3 washings. During the scouring process, a fleece may loose up to 50% of its original weight.
The rustleing sound produced when some silk is compressed.
This is a mechanical operation which, by breaking and beating the retted flax straw, separates the textile fibres in the stem of the plant from the woody matter and the bark. The next step would be ‘hackling’.
Sea Island Cotton
Finest of all cotton, very white and silk-like with staple of 1.5″ or better. Before the American Civil War, this type of cotton was raised on the islands of the Carolinas and Georgia. No longer raised in the United States today, it is raised in Mexico and Central America and goes into fine, expensive dress goods and men’s shirtings.
Fribs, or short lengths of wool resulting from cutting wool fibers twice in careless shearing. An excessive number of second cuts decreases the average fiber length, and depreciates spinning quality. See “Noils“.
Wool containing numerous seeds or an appreciable amount of vegetable matter.
The narrow edge of woven fabric that runs parallel to the warp. It is often made with stronger yarns, or in a tighter spacing, to prevent raveling. A fast selvedge encloses all of the picks. a selvedge is not considered fast when the filling threads are cut at the fabric edge after every pick.
Grease wool that lacks brightness due to the environment under which it is produced, though it is white after scouring.
Yarn spun from sliver carded (not combed) and pin-drafted on worsted spinning system machines.
Or silk gum. The gummy material holding the silk filaments together.
The outer or epidermal scaly edges on the wool fiber which can be seen under a microscope. Usually the finer the wool the greater the number of serrations. Serrations assist in felting by interlocking.
A term used to define the weft or warp density of a woven fabric, usually in terms of a number of threads per inch.
Setting the Twist
After you have plyed your wool, you need to set the twist. There are several approaches to this. One school of thought says that you wash your yarn and then dry it under tension. This approach is fairly popular with weavers. Another approach says that you wash your yarn and don’t dry it under tension. This approach is more popular with knitters. Yet another approach, promoted by Judith MacKenzie, says, really shock your wool and let it do what it’s going to do. This is done by washing in alternating hot and cold baths. A more detailed description is written up by Marie-Christine Mahe in “Yarn Abuse”.
Wool of extra good length, sound, and well grown.
The process of removing the fleece of wool from the sheep by means of hand shears or machine clippers.
The wool still on the pelt or skin.

Continuous protein filament produced by the larvae of various insects, especially the caterpillar when constructing its cocoon. The chief portion of commercial silk is produced in Japan and China. Characteristics: resiliency, aesthetics, elasticity and strength, warm in winter, cool in summer. See Reeled Silk and Doupioni.
The individual unit of yarn. Referring to a “single ply” this is almost guaranteed to make experienced spinners cringe.
Two-ply Sirospun yarns are made by spinning and twisting two strands together in a single operation. They are more elastic, less hairy and more compact than conventional two-ply yarns.
A vegetable fiber that is made into strong, coarse twine. It is used for binder twine, but should not be used to tie fleeces.
Any of various gelatinous or glutinous preparations made form glue, starch, etc., used for coating the threads.
The act or processing of applying “size“.
A length of yarn taken from the reel. See “hank“.
The processing of winding a skein of yarn.
The inferior quality wool that has been removed from the fleece.
A yarn which is made with slubs or lumps — possibly of various materials or colors — at various distances apart, according to the type of yarn desired. (This is being done on purpose, and consistently, as opposed to when you first start spinning. It’s not fair to call your first yarn produced a ‘slub yarn’. rb)
A method of testing the individual locks of raw wool. This is done by holding the two ends of a lock of wool and pulling your hands quickly apart. There should be a audible snapping sound — but no damage to the lock.
This is also done, on a very different scale, with a just-washed skein of yarn. For this situation, put your arms through a skein and ‘pop’ the skein. This will even out most kinks in the skein.
Small, curly or ‘kinked’ places in yarns.
Sodium Carbonate. Use as an alkali fixative for reactive dyes.

The process of separating a fleece into its various qualities according to diameter, length, color, strength, and other factors.
Sound Wool or Soundness
Wool that has a strong staple. Wool buyers or graders test the soundness of the wool by holding a staple at either end and snapping their fingers across the middle of it.
A yarn or fiber that has been dyed at irregular intervals.
According to the dictionary, “A rounded rod, usually of wood, tapering toward each end, used in handspinning to twist into thread the fibers drawn from the mass on the distaff, and on which the thread is wound as it is spun.

A fleece that is strong, regular, of good color and character, and nearly free of vegetation and dirt.
The process of making yarn by drawing out, twisting, and winding fibrous substances into yarn or thread.

An early spinning machine having more than one spindle, enabling a person to spin a number of yarns simulatenously.
A device used for spinning fiber into yarn or thread, consisting essentially of a single spindle drive by a large wheel (see “Great Wheel“) or a flyer unit driven by a treadle.
A spinner whose occupation is spinning. Updated to be politically correct.
Sponging removes residual shrinkage, or removal of any distortion in the size of the fabric caused by tension applied during production. The fabric is dampened with steam or water and allowed to dry in a relaxed state. Residual shrinkage (also called relaxation shrinkage) is different than the shrinkage caused by felting, and sponged fabrics are not necessarily shrinkproof.
The 6:7 months of wool produced by sheep shorn in the spring following fall shearing.
A yarn composed of fibers of silk which have not been reeled from the cocoon, but have produced by piercing the cocoon, and then shredding it into lengths of 3 to 15 inches, often from tussah cocoons. See “Doupioni“, “reeled silk“.
This swift has two rotating cylinders mounted on a vertical post. The cylinders can be shifted to adjust for different-sized skeins. An example of this can be seen on the Museum of the Welsh Woollen Industry page. Look in the lower right-hand corner of the image.
Wool that has become discolored by urine, dung, or whatever, which will not scour out white. Badly stained pieces should be removed at shearing before the fleeces are packed. See “skirting“.
A cluster or group of wool fibers naturally clinging together in the fleece.
The length of sheared locks obtained by measuring the natural staple without stretching or disturbing the crimp. The fiber regrowth or regeneration from one shearing to the next.
“Dyed-in-the-wool” is another term for stock dyeing because the fiber is still in the form of loose fleece. Most stock-dyed wool is made into woolen yarns. Worsted wool is never dyed until after it is combed and dyeing at this stage is called top dyeing. Both methods produce the highest penetration of dye and the highest quality of colored yarns. Wool dyed this way is also used to make speckled yarns of mixed colors and subtle heathers.
Bobbins used to store the yarn for subsequent plying. Depending on your school of thought, using a storage bobbin allows you more evenly wind on (then when you were spinning). This means that the plying process should also be more even.
This refers to the how much weight the fibers can bear. Some fibers, like flax, actually get stronger when wet.
This is when the fibers are pulled taut while spinning.
The bundle of prepared (hackled) flax fibers.
The practice of shearing or cutting a portion of the wool at varying lengths, from sheep used for show purposes. See “second cuts“.
Generally referred to as the perspiration of sheep and is naturally excreted from the glands at the roots of the wool. Suint consists of soapy compunds of potash and fatty acids, together with a little free fatty acid and saline matter. It is soluble in water. This is one part of what is called the grease on an unwashed fleece.
Superfine wool-from about 15 to 18 microns-is in a class by itself, comparable to fine cashmere, and is used to make fabrics of the highest quality. Superfine wool comes from strains of Merino sheep that have been developed to produce especially fine fibers. Sharlea.
A swift has an expanding core that can be adjusted to fit various skeins. This allows spinners to help keep the hank of yarn in some kind of order while unwinding it. I know of two main kinds of swifts: the umbrella and squirrel cage. The Le Clerc site has an image of a umbrella swift.
The combination of crimp and crinkle ranging from good crimp and good crinkle to no crimp and no crinkle.
A complex colorant derived from coal tar.
Synthetic fibers are organic compounds of high molecular weight and are formed by polymerization. In her book “The Textile Arts” Birrell suggests classifying them by how they are formed. Synthetic fibers formed by condensation reactions include polyamides (nylon) and ployesters (dacron). Synthetic fibers formed by addition reactions include vinyls, acrylic-vinyl, acrylic-nitril, and urethane.

Percentage of tops to noils. A 4:1 tear would refer to wool that had 20% waste.
A new fiber created from the wood pulp of specially selected trees, processed in a non-chemical, environmentally-safe way. Tencel was introduced to the world of apparel in 1992 and is the first new fibre introduction in over thirty years. The characteristics of the fiber are a subtle luster, high-wash stability, extremely low shrinkage, and good tear resistance.
Tentering is used to straighten the fabric and dry it. The fabric is stretched taut while steaming or drying and held in place with clips or pins, called tenterhooks. (Giving rise to that slang expression of suspense, “on tenterhooks.”)

Staples which are encrusted with wool grease and dirt at the weather end.
A continuous untwisted strand of wool fibers of predetermined length from which the short fibers (noil) have been removed in the combing process.
Total Fleece Weight
The weight of the entire raw fleece.
These are the shorter, less desirable flax fibers separated from bast line fibers in hackling. Tow linen is usually carded and spun into a woolen-style yarn. A wonderful use for tow linen is to knit bath mitts — a situation where you want all of the rough, scratch nature of this yarn.
Twists Per Inch (or Turns Per Inch).
The shorter flax fibers removed by hackling.
A fine cord of fibrous material spun out to considerable length, especially when composed of two or more plys twisted together.
flat bit under foot
A fleece showing strong breed-specific characteristics.
The wild silk of India and China where the silk worms are fed oak leaves. This causes a goldish color.
In spinning, this refers to the turns inserted into a yarn to bind its fibers together and thereby add more strength. It is usually indicated as turns per inch or tpi Greater twist would be caused by additional revolutions of the flyer on a set amount of fiber.
A term applied to yarn which is irregular, that is thick and thin, the thin places being below the count required and thick places above. The defect is caused by material being drafted at an irregular rate.
Traditionally, after a fleece is short, it is rolled into a bundle and tied off with a paper cord (so that it could be removed during the carbonization process). I believe that the paper cords are no longer being made.
A wool class sharing set characteristics. These are based on: breed, condition, length, spinning quality, soundness, style, and color.
A swift that opens up with a mechanism rather like an umbrella’s. The School Products site shows an example.
With wool, this refers to a fleece that varies in type over the body.
A woven fabric made from worsted yarn that has then been brushed. This produces a firm fabric with a tight weave hidden beneath a soft nap.
Wool in its original condition as it comes from a sheep. See also “Grease”.
Using the same direction as the preceeding spinning. So if you spun your singles “S” and then plyed them “S” you would have used up twist. You would also have a yarn that could be used in collapse fabrics.
Upright Wheel (also traveller or parlour)
Flyer mounted above the wheel, making the wheel more portable. Will usually fit on a car passenger seat with the seat belt holding it.
A synthetic nitrogen compound used with all classes of dyes. It also increases the solubility of the dyes.

This costly, luxurious fiber is finer than merino wool, with a rich, beautiful color that ranges from golden chestnut to cinammon. Each animal yields only a few ounces. The very limited supply of vicuna is controlled by the peruvian government. An image of a vicuna can be found at this site from the Blue Planet Biomes site.
Wool that has been clipped from a live sheep and that has not been previously processed to the stage where it contains twist. Noil is merely separated from long fibers in combing and is considered virgin wool.
The yarns that run the length of the loom. The warp yarns are pulled through the loom as the weft or filling yarns are woven across the warp to make the fabric.
Warping Board or Frame
A rectangular frame with strong pegs insered into its sides used to wind a warp.
A rotating frame that can be mounted horizontally or vertically. It’s used to wind a warp and help keep the threads in order.
Relatively new techniques have been developed to improve wool’s washability by making the fiber more resistant to felting and shrinkage. One process takes place before the yarn is spun. The loose fleece or combed top is chlorinated to remove the tips of the “scales” and then coated with an extremely fine resin. The resin masks the fiber’s scales and keeps them from interlocking, which is the cause of felting and shrinkage.
Wool washed in cold water while on the sheep’s back before shearing (industrial term).
In weaving, this refers to the part of the warp that cannot be used, often about 24-36 inches of the total warp. In spinning, this refers to the loss between the weight of fiber acquired and the weight of fiber that can be used. In spinning, the amount of dirt, tag ends, and unusable fiber are all part of the wastage.
Wool that is short, weak, and tangled, which often carries a high percentage of dirt or sand.
Another term for the cloth beam.
A thin fleece with poor staple formation and a large number of cross fibers.
The set of threads which crosses the warp at right angles. Depending on the use, there may be more than one weft used: ground weft, pattern weft, …)
Any fabric in which the warp is completely covered with weft.
A process by which the weight of a fabric is increased by impregnating it with mineral salts, starch, or other materials. This process was often used on yardage that was sold by the pound (e.g. silk).
A male sheep or goat castrated before sexual maturity. Because it’s (the operative phrase) isn’t caught up breeding, all of it’s nutrition goes into the fiber thus producing a better quality fiber. Fleeces from wethers can’t be entered into most wool shows but are worth watching for.
The process of spinning line flax where the fibers are smoothed by moistening them as they are spun. Traditionally, spinners licked their fingers and drank a lot of beer. More prosaically, you can get little wooden buckets to hold the water and can hang by a leather thong from the wheel. Or even a bowl of water. You should coat the inside part of the bobbin (where the fibers wind around) with paraffin or some other sealant if you don’t want to damage your bobbin.
Any fleece clipped after the first shearing is called wether wool. This wool is usually taken from sheep older than fourteen months, and these fleece contains much soil and dust.
An image of a wheel from the Carr House Museum in Canada.

The ability to draw moisture through the fiber.
This spinning term refers to winding the finished yarn onto a bobbin and secured to prevent unraveling.
A reel or swift.
Wool that is in-elastic and has poor spinning capacity. It is usually straight and may be the result of poor breeding.
A glue dye produced from Isatis tinctoria. Not as strong as Indigo.
The same as weft.
The fine, soft, curly hair that forms the fleece of sheep and certain other animals, characterized by minute, overlapping surface “scales” which give it its felting property. Characteristics: strong and resilient, soft and warm, wicks away moisture and dyes well for rich coloration.
The total yield of wool short during one season from the sheep of a particular region.
The person who sorts the “Wool Clip” into the appropriate “Grades”.
A variety of combs used to produce fibers for worsted spinning. The single-pitch and 2-pitch combs are what I call the peasant combs and are great for producing semi-worsted yarns. English combs are the multi-pitch combs (4- to 5-pitch) used to prepare a true worsted prep. (Obviously written by a Peter Teal fan. rb)
A term applied to yarns where the fibers were dyed prior to spinning; either in the loose fibers or as top or roving. See also “Yarn-Dyed”.
Wool in the Grease
Wool in its natural condition as it is shorn from the sheep.
The person in a shearing shed who skirts the fleece, then rolls it. The fleece is then classed.
Yarns made from shorter fibers of 1 to 3 inches, which stick out in all directions, giving the yarn its characteristic fuzziness. They are often singles yarns, and are thicker and more loosely twisted than worsted yarns. Fabrics made from woolen yarns are warm and fuzzy, such as flannels, tweeds and sweaters.
The woolen count is based on 1,600 yards of yarn per pound. With woolen yarns, this is called a “run”, so a “2 run” would refer to a 3200 yards
Woolen Spinning System
In this system, fiber is carded two or three times but not combed and goes directly from cards to the spinning process. Generally wool used for this system are shorter, have more crimp and better felting qualities. With this system it is possible to use wools of different types, lengths and character together in blends.
Worsted refers to two different processes which are combined to produce a smooth, clean yarn. Originally it referred to a woolen yarn manufactured in Worstead, Norfolk, England. It now refers to yarn (and fabric) made of long fibers, combed, and tightly twisted in spinning. Fabrics made from worsted yarns are smooth and cool to wear.
Fiber Preparation: Yarns spun from wool where the wool fibers are markedly ‘parallelized’ as distinct from woolen yarns in which anything but a parallel position is noticeable. In commercial yarns, almost without exception, worsted yarns are combed yarns. One of my reference texts states: “…but it is quite conceivable that wool fibres might be so parallelized by careful drawing and spinning that practically a yarn of worsted characteristics might be produced without combing.” [“Analysis of Woven Fabrics” by A.F. Barker & E. Midgley] For me, the important word is ‘practically’. Traditionally, worsted yarns were from fibers 3+ inches in length, but this is no longer true as now many shorter wools are also worsted spun.
Spinning: The spinning process where the twist is not allowed into the drafting triangle. They are usually plied yarns, and are finer and more tightly twisted than woolen yarns.
The worsted count also expresses the number of hanks required to make a pound of yarn. A hank of worsted wool is equal to 560 yards. So 1 wc = 560 yards of cotton, the coarsest worsted yarn. Worsted sizes are expressed the reverse of cotton sizes. A two-ply number 6 worsted yarn would be expressed as 2/6 wc and would yield 1680 yards per pound. You can covert worsted count to cotton count by multiplying the cc by 1.5, or wc = cc x 1.5. See “Bradford Count“.
Worsted Spinning System
A system of yarn production designed for medium or longer wools, and other fibers. The suitable fiber lengths vary from 2.5 to 7 inches. The process includes, opening, blending, cleaning, carding, followed by combing, drawing and spinning. These yarns are compact, smooth and more even and stronger than similar yarns spun using the woolen system.
Used often with weaving overshot patterns. This is the order of treadling that will give the finished fabric a squared pattern with a diagonal line running through it.
A way of removing excess moisture by centrifugal fource. Hold onto the end of the skein firmly and spin it around like a heliocopter blade.
Yardage: The amount, or length of a fabric expressed in yards.
Yard Goods: Fabric sold on a retail basis by the running yard.
Yarn: A continuous strand of textile fibers that may be composed of endless filaments or shorter fibers twisted or otherwise held together. It may be made up oof vegetable (linen, hemp, jute, sisal, ramie,cotton), animal (wool, mohair, silk), or artificial fibers (gold, silver and other metals rayons, nylon, Orlon). Yarns are utilized in making fabric. Yarn is charachterized by its composition, its thickness (or grist or count), number of strands (or plies), direction and degree of twist, and the color. OR Yarn: A generic term for a continuous strand of textile fibers, filaments, or material in a form suitable for knitting, weaving, braiding, or otherwise intertwining to form a textile fabric.
Yarn Beam: The same as a “Warp Beam”.
Yarn Construction: A term used to indicate the number of singles yarns and the number of strands combined to form each successive unit of plied yarn, or cord.
Yarn-Dyed: A term applied to yarns dyed after spinning. See also “Wool-Dyed”.
Yarn Number : A relative measure of the fineness of yarns.
Yarn Quality : Various grades of yarn designated by the producer with respect to performance characteristics.
A sheep or goat that is 12-18 months of age.
A white fleece can yellow for a variety of reasons. Yellow stains can be caused by urine or feces, and by bacteria or fungus. Alkali and light can also cause yellowing in wool.
Most stains cannot be removed by washing. Bleaching will probably damage the fleece.
Yield: 1. Number of linear or square yards of fabric per pound of fiber, or yarn. 2. The number of finished square yards per pound of greige fabric.
Yolk: The natural grease and suint covering on the wool fibers of the unscoured fleece, and excreted from glands in the sheep’s skin. Usually the finer the wool, the more abundant the yolk. Yolk serves to prevent entanglement of the wool fibers and damage during growth of the fleece.
Young’s Modulus: A property of perfectly elastic materials, it is the ratio of change in stress to change in strain within the elastic limits of the material. The ratio is calculated from the stress expressed in force per unit cross-sectional area, and the strain expressed as a fraction of the original length.
Spinning counterclockwise. Traditionally, the direction “plied” yarns are spun.
