Abstract

Cotton knitted fabrics were manufactured with gauge number 20 G by circular knitting machine with conventional ring spun yarn and torque-free ring spun yarn. Torque-free ring spinning is a new spinning technology that produces yarns with low twist and balanced torque. This study examined whether the impact of biopolishing and UV absorber treatment on UV protection properties on cotton knitted fabric made of torque-free ring spun yarn is different. Biopolishing agent and UV absorber were used to treat the cotton knitted fabrics after scouring and bleaching. The UV protection properties were measured in terms of UV protection factor (UPF) and UV ray transmittance. Experimental results revealed that knitted fabric made from torque-free ring spun has better UPF than knitted fabric made from conventional ring spun yarn in untreated and biopolished states. However, knitted fabric made from conventional ring spun yarn has better UPF than knitted fabric made from torque-free ring spun after UV absorber treatment and combined UV absorber and biopolishing treatment.
