Effects of Yarn Count on Crimp% and Take-Up% of 2/1(S) Twill Woven Fabric.

Abstract

In this experiment, we have attempted to investigate the effects of yarn count on crimp% and take-up% of #x1D7D0;#x1D7D0; #x1D7CF;#x1D7CF; (S) twill weave design. Experimental studies were conducted by woven fabrics with five different yarn count. For this purpose five woven fabric samples, each of #x1D7D0;#x1D7D0; #x1D7CF;#x1D7CF; (S) twill designs with different count, were made on same rapier weaving machine by keeping all parameters constant with same atmospheric condition. Crimp% and take-up% was calculated by dividing the difference between umcrimped length and crimped length of yarn by crimped length of yarn and uncrimped length of yarn respectively. It was observed that when the count of yarn changes the crimp% and take-up% of yarns are affected. Finally found that, as expected, with increase of yarn count the crimp% and take-up% of warp yarn decreases while crimp% and take-up% of weft yarn increases.
