Study on Single Jersey Knitted Fabrics Made From Cotton/ Polyester Core Spun Yarns. Part II: Moisture Management Properties

Abstract

This paper discusses the influence of core sheath ratio, twist and loop length on the moisture management properties of cotton/polyester core spun knitted fabrics. Box behnken, a three level- three variable factorial design was used to study the interactive effects of the dependent variables. Fifteen single jersey fabrics were knitted according to the statistical run and tested for physical and moisture management properties. Increase in polyester percent increases the moisture management properties which decreases the fabric weight and dries quickly. High twisted and tight structured fabrics hold moisture and spread more. The wetting time of all the knitted structures at the top and bottom surface were rated as fast (i.e. 3 to 5). Absorption rate of all the fabrics at the top and bottom surface were graded as medium range. Maximum wetted radius at the top and bottom surface were graded as very large (i.e. >22). Spreading speed of the top and bottom surface were rated as very fast (i.e. >4). 100% cotton knitted fabrics showed excellent (i.e. >400) accumulative one-way transport index and remaining samples were rated as very good (i.e. 200-400). The overall moisture management capacity of the 100% cotton knitted fabrics were rated as excellent compared to core spun knitted fabrics which were graded as very good.
