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.

Enzymatic compositions and methods for producing stonewashed look on indigo-dyed denim fabric and garments

A granular enzyme composition is produced, having reduced tendencies to form dust and leave residue, and exhibiting improved stability and delayed release characteristics. The granular composition comprises a core, an enzyme layer and an outer coating layer. The enzyme layer, and optionally the core and outer coating layer, contain a vinyl polymer. The vinyl polymer is preferably a hydrolyzed polyvinyl alcohol or copolymer thereof. The hydrolyzed polyvinyl alcohol has varying degrees of hydrolysis in the core, enzyme layer and outer coating layer. Also disclosed are methods for making such enzyme-containing granules, the methods having greatly reduced processing time.
