During stonewashing of denim fabric or garments, redeposition of blue color often occurs back onto the surface of the denim or other parts like pocket parts. The invention relates to the inhibition of backstaining or redeposition during the stonewashing process by applying a lipolytic enzyme, preferably cutinase, thereby avoiding that the blue colour redeposites on the fabric or garment.
Lors du délavage à la pierre d'un tissu ou de vêtements du type denim, il se produit souvent une redéposition de la couleur bleue sur la surface du denim ou autres parties telles que les poches. L'invention concerne un procédé d'inhibition de cette recoloration ou redéposition au cours du procédé de délavage à la pierre, lequel procédé consiste à appliquer une enzyme lipolytique, de préférence une cutinase, ce qui permet d'éviter que la couleur bleue ne se redépose sur le tissu ou le vêtement.
