Abstract:

Needle punching is the oldest method of producing nonwoven products. The first needle punching loom in U.S. was made by James Hunter machine co. in 1948. Then in 1957, James Hunter produced the first high speed needle loom, the Hunter model 8 which is still used today.

The needle punching system is used to bond dry laid and spun laid webs. The needle punched fabrics are produced when barbed needles are pushed through a fibrous web forcing some fibers through the web, where they remain when the needles are withdrawn.If sufficient fibers are suitably displaced the web is converted into a fabric by the consolidating effect of these fibers plugs or tufts. This action occurs in needle punching occurs around 2000 times a minute.
