Optimizing color fading effect of cotton denim fabric by enzyme treatment

Abstract

In this article, the effect of enzyme treatment using neutral cellulase on the color fading property of cotton denim fabric was studied. Four enzyme processing parameters namely treatment temperature, treatment time, pH value, and agitation were considered. To investigate the optimum condition for the enzyme treatment, an orthogonal analysis was used and, based on the K/S summation value (K/S Sum), the optimum condition for enzyme treatment in this study was treatment temperature ¼ 50 C; treatment time ¼ 30 min; pH value ¼ 8; and agitation ¼ 50 steel balls (simulated mild agitation) for the best color fading achievement with desired worn and aged effect. Meanwhile, the level of importance based on the orthogonal analysis was in the order: treatment temperature > treatment time > agitation > pH and the effect of each processing factors was also discussed. In addition, other properties like CIE Lab values, weight loss, and color fastness to laundering and crocking were also evaluated.

Orthogonal analysis for rechargeable antimicrobial finishing of plasma pretreated cotton

“…That is, temperature of curing has the I I I 2 I II II II 3 I III III III 4 II I II III 5 II II III I 6 II III I II 7 III I III II 8 III II I III 9 III III II I greatest impact on the experimental result, and concentration of DMH has a comparatively less impact, next factor in the order is duration of chlorination, and the last one is concentration of bleaching solution (Chuanwen et al 2010;Kan et al 2011). The best level is suggested by orthogonal analysis based on the mean value of the testing factors.…”

“…Orthogonal array testing strategy (OATS) analysis was used for determining the optimum treatment conditions [25][26][27][28][29]. Four variables which have been used previously [25][26][27] were adopted, i.e., the concentration of DMH, curing temperature, concentration of the bleaching solution, and the duration of chlorination and their respective effects on antibacterial properties were investigated.…”

Deposition of nanoparticle multilayers to improve mechanical properties of denim fabrics

“…Nowadays, users are taking more care of denim garments' lightweight, smoothness and softness properties. Especially, the laundering and the special treatments (enzyme and/or pumice washing for aged look) on denim garments are much spilled in the world (Card, Moore, & Ankeny, 2005;Kan, Yuen, & Wong, 2011;Sarıışık, 2004;Tarhan & Sarıışık, 2009;Vijayalakshmi & Ramachandran, 2012). The treatments of finishing denim garments during washing are the important parameters influencing cloth shade and the fabric mechanical properties (Khedher, Dhouib, Msahli, & Sakli, 2009).…”
