Enzymatic methods for dyeing with reduced vat and sulfur dyes

A method for dyeing a material, comprising:

• (a) treating the material with a dyeing system which comprises one or more reduced vat dyes or one or more reduced sulfur dyes;
• and
• (b) oxidizing the one or more reduced vat dyes or one or more reduced sulfur dyes adsorbed onto the treated material with an oxidation system comprising (i) an oxygen source and one or more enzymes exhibiting oxidase activity, selected from the group consisting of bilirubin oxidase, catechol oxidase, laccase, o-aminophenol oxidase, polyphenol oxidase, ascorbate oxidase, and ceruloplasmin, or (ii) a hydrogen peroxide source and one or more enzymes exhibiting peroxidase activity, is a peroxide or a haloperoxidase, to convert the one or more reduced dyes to their original oxidized insoluble colored forms;
• wherein the material is a fabric, yarn, fiber, garment or film made of cotton, diacetate, flax, fur, hide, linen, lyocel, polyacrylic, polyamide, polyester, ramie, rayon, triacetate, viscose or.
