Abstract
A method of introducing into the surface of dyed denim fabric or garment, localized areas of variations in colour density, the method comprising contacting the fabric or garment with an aqueous composition comprising an effective amount of a pectolytic enzyme preferably selected from the group consisting of pectin lyases (EC 4.2.2.10), galactanases (EC 3.2.1.89), arabinanases (EC 3.2.1.99), pectin esterases (EC 3.1.1.11), mannanases (EC 3.2.1.78), polygalacturonases (EC 3.2.1.15) and pectate lyases (EC 4.2.2.2) at a pH of the aqueous composition between 3 and 11 and a temperature of or below 90.degree.
