Nap raising-warp knitted fabrics with rollers to give a width - stretch

摘要

Pairs of squeeze rollers, with intermediate directional rollers are used to lead the warp knitted fabric to the cylinder of the nap raising machine. The purpose of the intermediate rollers is to maintain the width stretch effect imposed by the squeeze rollers, and to prevent the fabric's natural elasticity to cause reassertion and lead to creases before entering the nap raising phase.
