denim with a sulphur bottom or with a sulphur top i e the denim is first dyed with a sulphur dye and then with an indigo dye or vice versa the look of the twill fabric as described in the present invention may be obtained by various processes a preferred process comprises the following steps i selecting the desired textile cutting pattern for the garment e g the jeans v optionally subjecting the piece of garment e g the pair of jeans to a desizing treatment vi subjecting the garment e g the pair of jeans to an abrasion treatment with an efficient amount of a cellulolytic enzyme in an aqueous medium essentially free of bleaching chemicals the skilled person in the art will realise that the effective amount of a cellulolytic enzyme will vary depending upon a number of well understood parameters including the purity and the specific activity of the cellulase the contact time the ph the temperature of the aqueous process medium the presence of abrasives pumice perlite diatomaceous earth eco balls and the machinery used for fabric e g denim wet processing when processing fabric in particular denim the mechanical action is a very important parameter to consider in order to obtain the desired abrasion level the machine design plays an important role in getting the desired abrasion level abrasion comes from fabric to fabric fabric to metal or fabric to stone abrasive contact the.
