COMPOSITION FOR INTRODUCING COLOR DENSITY CHANGE INTO CELLULOSIC FABRIC, ESPECIALLY, INDIGO DYED DENIM

摘要

PURPOSE: To obtain a cellulosic fabric, particularly an indigo dyed denim, having a 'stone-washed' distressed or 'used and abused' look without subjecting the cellulosic fabric to a stone-washed treatment, by treating the cellulosic fabric, particularly the indigo dyed denim, with a cellulase enzyme composition. CONSTITUTION: This woven fabric or garment, particularly an indigo dyed denim, scarcely damaged, having changed colors, and having a 'stone-washed' distressed or 'used and abused' look without subjecting the cellulosic fabric to a stone-washed treatment is obtained by bringing the woven fabric or garment, particularly the indigo dyed denim, into contact with an aqueous composition containing a cellulase enzyme, especially an enzyme obtained from a mold, in an amount of at least 2,500 CMC units per liter of the aqueous composition and a nonionic surfactant comprising the units of ethylene oxide, propylene oxide or their mixture in an amount of about 0.1-1,000 pts. per 1,000,000 pts. of the aqueous composition, for at least 5 min, and then stirring the mixture for 30-720 min.
