During the enzymatic "stone washing" of a denim fabric and/or garments, an undesirable redeposition of blue dye often occurs on the surfaces of the denim. The invention relates to a means of overcoming this problem using an enzyme composition comprised of Trichoderma endoglucanases and Trichoderma cellobiohydrolases that has been partially digested by a protease enzyme to separate its core and binding domains. The use of this composition reduces the redeposition of the blue dye and hence improves the stone washing process relative to using a redepositing or backstaining cellulase.
