Disclosed are improved aqueous processes and compositions for obtaining a "stonewashed" look in colored fabric while reducing the amount of redeposition of colorant onto the fabric, as well as the fabrics produced from these methods. In particular, the disclosed methods as directed to contacting fabrics with fungal cellulase composition which is substantially free of CBH type components. Fabrics so treated show reduced redeposition of colorant. L'invention concerne des procédés et des compositions aqueux améliorés permettant d'obtenir un effet délavé avec un tissu de couleur tout en réduisant la redéposition du colorant sur ce dernier, ainsi que les tissus produits selon ces procédés. Plus précisément, ces procédés consistent à mettre des tissus en contact avec une composition de cellulase fongique pratiquement exempte de composants du type exo-cellulobiohydrolase. Ce type de traitement permet de réduire la redéposition de colorant sur les tissus.
