Nonwoven & Composites
Needlepunching
A formed web of fibers is fed into a machine with a bed of barbed needles shaped like fishhooks, 2 to 3 inches long. As the needles stitch up and down through the web, the barbs pull a few fibers through it, causing them to entangle and interlock with the other fibers. This results in a fabric that is strong, bulky, yet soft.

 

Stitch-bonding
Fiber webs are stitched through to hold the fibers together. Loops of fiber are formed and then chain-stitched through the web.



Powder-bonding
This utilizes a dry laid process to first form the web and thereafter applying a powdery plastic adhesive onto it. This is then thermally bonded by passing it through a series of hot ovens and between heated calendars to produce the finished nonwoven.
