Abstract

This invention discloses a mixture of dispersed dyes, which is composed of: one or more dyes (shown in formula I) 55-95 wt.%, one or more dyes (shown in formula II) 1-30 wt.%, and one or more dyes (shown in formula III) 1-15 wt.%. When then mixture of dispersed dyes is used to dye polyester fiber materials, by adjusting the ratio of different components, organic fabrics with such advantages as good luster, high dispersibility, high sunlight resistance, high washing resistance and high sweat resistance can be obtained.

Description

(1) Technical field [0001] The invention relates to a disperse dye mixture, in particular to a disperse dye mixture for printing and dyeing polyester and its blended fabrics. (2) Background technology [0002] With the rapid development of new polyester fibers in recent years and the improvement of people's requirements for textiles, correspondingly, higher requirements have been put forward for the dyeing performance and environmental protection performance of the dye itself. That is to say, the dyestuffs are required to have high lifting power and various dyeing fastnesses. [0003] Azo dyes occupy the largest market share due to their relatively simple synthesis and easy realization of large-scale industrial production. However, from the perspective of existing azo dyes, they still cannot fully meet the requirements in application performance such as lifting power and color fastness, such as the compound dye disclosed in the patent JP10-77583.
