The invention relates to bisazo compounds of formula (Ia) or (Ib) wherein R1 represents hydrogen or methyl; the groups X independently represent -CH¿2?CH2- or -CH2CH2CH2-; R?2, R3, R4¿ independently represent hydrogen or methyl; A represents an anion; and n represents the valency of A. The invention also relates to the use of said bisazo compounds for dyeing, especially paper, and to dyes containing bisazo compounds.
摘要:
The present invention relates to methods of dyeing a material, comprising (a) soaking the material in an aqueous solution which comprises one or more mono-, di-, or polycyclic aromatic or heteroaromatic compounds; and (b) treating the soaked material in an aqueous solution with (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 fur, hide, leather, silk or wool.
摘要:
The present invention relates to methods of dyeing a material which involve contacting the material with a dyeing system which comprises: (a) a mixture of (i) an aromatic diamine and (ii) one or more of a naphthol and an aminonaphthalene and (b) an oxidation system comprising (i) a hydrogen peroxide source and an enzyme exhibiting peroxidase activity or (ii) an enzyme exibiting oxidase activity on one or more of the compounds of mixture (a). The material may be a fabric, yarn, fiber, garment or film made of fur, hide, leather, silk or wool, or made of cationic polysaccharide, cotton, diacetate, flax, linen, lyocel, polyacrylic, synthetic polyamide, polyester, ramie, rayon, triacetate, or viscose.
摘要:
Fabrics, formed, for example, by joining stitch and loop yarns to form a fabric prebody, with the loop yarn forming in loops that overlay the stitch yarn at the technical face and back of the fabric prebody, and thereafter finishing the fabric prebody to form raised fleece at both surfaces, have a first surface and an opposite, second surface of contrasting, i.e., different, colors. Regions of one or both surfaces may be treated to resist raising so that design elements of the raised or fleece regions stand out in relief, forming surface(s) with contour. Methods of forming the fabrics are also described.
