Abrasion of polyester fabrics containing staple weft yarns: Color strength and color difference values

Abstract

This paper assesses the color difference and color strength values (K/S) obtained for eight disperse-dyed polyester fabric samples with different fabric construction parameters (weft yarn count, weft density, and fabric weave) after three different sets of abrasion cycles. Warp yarn type and number, warp density, and warp yarn twist were the same for all fabrics. The K/S values of the abraded fabrics and color difference values between the control fabric (dyed but not abraded) and abraded fabrics were calculated. The main differences in the K/S and color difference values were observed between 0- 2,500 abrasion cycles. The high tenacity of the polyester fibers during testing caused fuzz and pilling formation on the fabric surface that led to decreased K/S values and color differences.
