Zusammenfassung:	PCT No. PCT/DK94/00078 Sec. 371 Date Sep. 18, 1995 Sec. 102(e) Date Sep. 18, 1995 PCT Filed Feb. 25, 1994 PCT Pub. No. WO94/19528 PCT Pub. Date Sep. 1, 1994A process for providing improved localised variation in the color density of the surface of dyed fabrics by reducing backstaining, the process including treating a dyed fabric with a cellulytic enzyme in an aqueous liquor and adding a sufficient amount of chelating agent to the liquor to reduce the concentration of di- or trivalent cation to less than 20 mg/l.
