Diamond and Diapers


These Designs, from the point of view of their construction, can be regarded as the further development of twill weave.

DIAMONDS

Those that are symmetrical about their vertical and horizontal axes which can be produced with the aid of point draft and vertical waved twilled peg-plan.

DIAPERS

Those that are symmetrical about their diagonal axes, these are based on herringbone draft and vertical waved twilled peg-plan.

Ø Diamond is constructed on wavy twill while Diaper is constructed on herringbone twill.

DIAMOND WEAVE

Principle of Construction:

True diamond shapes converge into a vertex and for this reason most designs of this type can be constructed economically on the point draft basis. The structure may be developed in following two ways:

1. By employing a vertical waved twill or zigzag as the lifting plan in conjunction with the point draft.

By indicating a diamond base and building up the design symmetrically on each side of the centre thread.

· While this represents the same twill arrange to zigzag vertically.

· Two such repeats are given in each direction.

First method is most commonly employed to produce economical diamonds.

DIAPERS CONSTRUCTION

This class of weave will form cut effect or dice effect with the implementation of herringbone twill. This effect is used in ornamentation, shirting, etc.

Principle of Construction:

Ø The simplest weaves of this type are produced as a further development of the herringbone twill, in which the principle of opposing a warp float on the one side of the design by a weft float on the other is extended in both directions, i.e. horizontally and vertically.

Ø In this manner a design is formed in which the typical herringbone cut splits the design into four quarters, the diagonally opposite caters being similar.

Ø These structures are frequently employed as they are capable of forming large design repeats with considerable economy in the number of heald to be used.

v Diapers can also be constructed on the herringbone draft basis provided that the twills from which they were originated fall into a certain specific category the characteristic of such twills are:-

o They are even sided

o Their repeat splits in two halves each of which is symmetrical within itself.

o The lifts in each of the two halves are diametrically opposite

v Even sided twill containing more than two lines of float which do not split in the manner indicae than two lines of float which do not split in the mannner self.

v twills from which they were originated falll ted above cannot be woven with the economical herring bone draft.

v Warp and weft faced twills can also be used to produce diapers on the herring bone reversal but owing to the very prominent quartering of the repeat a distinct check effect is produced and for this reason, such effects are frequently termed as “dice checks”.

v In additional to the herring bone based diapers many other diaper forms can be constructed without a preconceived base.

Difference

Diamond weave Diaper weave
It looks like a diamond It looks like a dice checks
It can be formed by two methods

o Baseline

o Wavy twill

It can be formed by using herring bone twill
Diamond is asymmetrical on both vertically and horizontally. It is only diagonally similar.
This is used for dress material and furnishing fabrics. This is used for dress materials.
This weave is produced with point draft It is not produced with point draft.
