A pairwise comparison of cotton-polyester blend yarn’s characteristics produced with vaying percentage of polyester by analytical hierarchy process.

Abstract

The current study reveals a comparison on the characteristics of cotton-polyester blend yarns, produced with varying percentage of polyester. The research was carried out by producing five types of blend yarns of 30 Ne such as 100% cotton yarn, CVC 60-40 (60% Cotton and 40% Polyester), CVC 55-45 (55% Cotton and 45% Polyester), PC 50-50 (50% Cotton and 50% Polyester) and PC 65-35 (65% Cotton and 35% Polyester) and are tested by Count Tester, Uster Evenness Tester-5 and Lea Strength Tester. The quality parameters varied with the change of percentage of Polyester fibers. With the increase of amount of polyester, the Unevenness and Coefficient of Variation (U% and CV%), Imperfections Index (IPI), Hairiness Index (H), Count Strength Product (CSP) improves due to the characteristics of Polyester such as longer fiber length, higher fiber uniformity, no neps and higher strength. The pairwise comparison by Analytical Hierarchy Process (AHP) of both quality parameters (at level 1) and different blend ratio (at level 2) also indicated the reliability of the work.
