  • Enzymatic compositions and methods for producing stonewashed look on indigo-dyed denim fabric and garments
    Patent number: 6251144
    Abstract: During the desizing and enzymatic stonewashing of denim fabric and/or garments, redeposition of blue color often occurs back onto the surfaces of the denim. The invention relates to a redepositing or backstain inhibiting composition and a method requiring the inclusion of an added protease prior to, during or subsequent to the stonewashing process which reduces the redeposition of the blue dye and hence improves the stonewashing process when using redepositing or backstaining cellulases to give an appearance closer to that when using stones alone or nonredepositing cellulases in the stonewashing process.
