Abstract

A dispersed red dyestuff compound is made up of the one or a few dyestuff A, the dyestuff B and the assistant which the weight percent of the A is 50-99% and the B is 1-50%. The superfine Dacron dying by the dispersed red dyestuff compound has the high rate of dye-uptake, good firmness and dispersibility. So it is proper for the superfine Dacron material.

Description

(1) Technical field [0001] The invention relates to a disperse red dye composition, in particular to a disperse red dye composition applied to polyester superfine denier fibers. (2) Background technology [0002] Superfine fiber is a new generation of synthetic fiber that has developed rapidly in recent years. It has been widely used because of its many unusual characteristics. However, in terms of dyeing and finishing technology, it faces new problems that synthetic fibers have not encountered. It is manifested as poor level dyeing, light color and low color fastness. For this reason, it is necessary to provide a group of dyes suitable for superfine denier dyeing with high dyeing rate, good fastness, low heat migration resistance and good level dyeing property. [0003] Patents US4734101, US5304222, and CN1631991 respectively provide several monochromatic dye compound, but when applied to superfine polyester fiber dyeing, the performance still cannot fully meet the require...
