The Influence of Fabric Weight in the Enzymatic Process (Depilling) of Cotton Knitted Fabric

Abstract

Enzymes are gaining an increasingly important role as a tool in various wet textile pretreatment and finishing processes (Stanescu, 2002; Thiry, 2001; Cavaco-Paulo, et al. 1998; Heine and Höcker, 1995)[12]. Within 5 to 10 years, wet textile production processing will be shifted from conventional wet textile pretreatment and finishing procedures substantially towards sustainable processes, because of increasing governmental and environmental restrictions and the decreasing availability of fresh water. We analysed the influence of enzymatic treatment process(depilling) using an acid cellulase enzyme on the different weight of cotton knitted fabrics(single jersey) at different time duration and find that depilling effect vary with fabric properties such as density of the fabric which is related with GSM of fabric. The action of enzyme hydrolysis was studied by pilling grade and fabric strength loss percentage.
