Abstract

See full text

The disclosure relates to a method for improving the alkali resistance and oxidation resistance of a benzothiazole disperse dye, and belongs to the field of disperse dyes. In the disclosure, 4 kinds of diazo components and 8 kinds of coupling components are used in designing and synthesizing 28 thiazole heterocyclic azo disperse dyes, and the alkali resistance and oxidation resistance of the disperse dyes are improved. Structure confirmation is performed on the synthetic disperse dyes, and the alkali resistance, oxidation resistance and other dyeing properties of the disperse dyes are tested. According to the method for improving the alkali resistance and oxidation resistance of the benzothiazole disperse dye provided in the disclosure, a relationship between a dye structure and the alkali resistance and oxidation resistance is determined, the disperse dyes with excellent alkali resistance and oxidation resistance are obtained, and the dyeing performance is stable under a dyeing condition of 10 g/L of sodium hydroxide or 5 g/L of hydrogen peroxide. This kind of dyes can be applied to a one bath for bleaching and dyeing of polyester and cotton and a one bath for deweighting and dyeing of polyester, dyeing and finishing in a short process are achieved, and great ecological and economic benefits are obtained.
