Disperse-reactive dyes suitable for dyeing and printing polyester-cellulose blended fibres.

摘要

Disperse-reactive dyes suitable for dyeing and printing, in one step only, polyester-cellulose blended fibres are described, which are comprised in the general formula D - (SO2- C2H4OCOR)n wherein: D is the residue of the molecule of a dye of the azo, anthraquinone methinic or quinophthalonic series, free from solubilizing groups such as the sulphonic and the carboxylic groups n is a number equal to 1 or 2 R is an alkyl, C1-C8, optionally substituted by halogen or CN an alkenyl C2-C8, optionally substituted by halogen or CN an alkoxyl C1-C8 a cycloalkoxyl HN-alkyl C1-C4 HN-halogen alkyl C1-C4 N(alkyl C1-C4)2. Methods of preparing the dyes and of applicating same on said blends are described as well.
