Effect of different washing processes, twill direction and yarn types on the performance properties of denim fabrics

Abstract

This study aims to investigate the effects of different washing processes, twill directions, and yarn types on the performance properties of denim fabrics. For this purpose, 100% cotton elastane, 85% cotton/15% Modal elastane, and 85% cotton/15% Tencel elastane including denim fabrics were produced with two different weaves (3/1 Z and 3/1 S), and four different industrial washing operations were applied to these denim fabrics. In addition, untreated fabrics (not industrially washed) were used to compare the performance of the fabrics before and after industrial washing. The highest warp-breaking strength values were observed in the rinse-washed fabrics, whereas the highest shrinkage, elasticity, and rubbing fastness values were observed in the bleach-washed fabrics. In addition, it can be said that industrial washing processes reduce the growth values of untreated fabrics and reduce the bagging during use. Although the crystallisation degree of Tencel fibre is higher than that of Modal fibre, it was concluded that the use of Modal fibre with cotton increased the strength values. In contrast, the use of Tencel fibre with cotton increased the elasticity and rubbing fastness values of the denim fabrics.
