Quality characteristics of polyester/viscose and polyester/cotton two-ply yarns

Abstract

The inter-relationship between the characteristics of single and double yarns made of polyester/viscose and polyester/cotton has been studied. The major yarn characteristics, such as unevenness, imperfections, single yarn strength (RKm), strength CV%, elongation-at-break and yarn hairiness, of double yarns are found to be related to the respective properties of single yarns. The mass CV%, total imperfections, single yarn strength, elongation-at-break and hairiness of double and single yarns are highly correlated. Thick places and single yarn strength CV% show medium correlation.
