The Effect of Cellulase and Laccase Enzymes on Denim Color

Denim washing is one of the finishing processes with the great application due to creating special appearance and updating clothes. In current study, the effects of laccase is considered in different methods of washing including laccase alone, laccase along with acid cellulase and along with neutral cellulase. The color changes of different samples are compared by colorimetric indices for garment surface and back and also white pocket and also the effluents in the remaining baths of stonewashing were also monitored by spectrophotometer after each processing. The tensile and the weight changes of samples in different treatment are measured within the standard methods. The results show that co-application of laccase with cellulase increasing the lightness and decreasing the staining on both back of garment and white pocket. With increasing of laccase in mixture of enzymes back-staining was decreases. The result of spectrophotometer was recognized that laccase decomposes the removed indigo during stone washing. J.
