Abstract
Methods of dyeing a material, comprising treating the material with a dyeing system which comprises (a) one or more mono-, di- or polycyclic aromatic or heteroaromatic compounds, and (b) (i) a hydrogen peroxide source and an enzyme exhibiting peroxidase activity or (ii) an enzyme exhibiting oxidase activity on the one or more aromatic or heteroaromatic compounds; wherein the material is a fabric, yarn, fiber, garment or film made of cotton, diacetate, flax, linen, lyocel, polyacrylic, synthetic polyamide, polyester, ramie, rayon, tencel, or triacetate.

- sulfonato;
- sulfamino;
- sulfanyl;
- amino;
- amide;
- nitro;
- azo;
- imino;
- carboxy;
- cyano;
- formyl;
- hydroxy;
- halocarbonyl;
- carbamoyl;
- carbamidoyl;
- phosphonato;

- C.sub.1-18 alkyl sulfonyl;
- C.sub.1-18 alkyl imino and amino which is substituted with one, two or three C.sub.1-18 alkyl groups;
- wherein each C.sub.1-18 alkyl;
- C.sub.1-18 alkenyl and C.sub.1-18 alkynyl group may be mono-, di or poly-substituted by any of the proceeding functional groups or substituents;
- and (b) (i) a hydrogen peroxide source and an enzyme exhibiting peroxidase activity or (ii) an enzyme exhibiting oxidase activity on the one or more aromatic or heteroaromatic compounds;
- wherein the material is fabric, yarn, fiber, garment or film made of cotton, diacetate, flax, linen, lyocel, polyacrylic, synthetic polyamide, polyester, ramie, rayon, tencel or triacetate.
