摘要

Process for removing excess dye from fabric or printed wire or dyeing newly manufactured, comprising treatment with a rinse solution comprising at least one enzyme selected from the group consisting of enzymes exhibiting peroxidase activity or laccase activity, an agent oxidation, and at least one mediator wherein the mediator is a compound of the general formula I: where R1, R2, R3, R4 are individually selected from the group consisting of hydrogen, halogen, hydroxy, formyl, carboxy and salts and esters thereof, amino , nitro, C1-C12, C1-C6 alkoxy, carbonyl (C1-C12), aryl, in particular phenyl, sulfo, aminosulfonyl, carbamoyl, phosphono, phosphonooxy, and salts and esters thereof, wherein R1, R2, R3, R4 may be substituted with R5, wherein R5 represents hydrogen, halogen, hydroxy, formyl, carboxy and salts and esters thereof, amino, nitro, C1-C12, C1-C6 alkoxy, carbonyl (C1-C12), aryl, particular phenyl, sulfo, aminosutfonil, carbamoyl, phosphono, phosphonooxy, and salts and esters thereof, [X] represents a group (-N = N-), (-N = CR6-) m, (-CR6 = N-) m, (- CR7 = CR8-) m, m is 1 or 2, wherein said mediator is present in said rinse solution at a concentration of 1 microM to 1 mM, and - optionally additives.
