Abstract

The invention provides a disperse dye composition and a disperse dye. The compositions comprises at least one component A shown as a formula (I), at least one component B shown as a formula (II) and at least one component C shown as a formula (III), wherein based on the component A, the component B and the component C, the mass percentage of the component A is 1 to 49 percent, the mass percentage of the component B is 50 to 98 percent, the mass percentage of the component C is 1 to 49 percent. The disperse dye composition of the invention can used for dyeing in liquid and paste states after micronization or in powdery and granular states after being dried by spray drying. Disperse dyes made by the formula of the disperse dye composition of the invention allow for adjustment of proportion of different dyes in the dyeing of polyester fiber materials to obtain dyed cloth with colors from deep blue to dark and the obtained dyed cloth has the advantages of bright color, good dispersivity, sun fastness, wash resistance, sweat resistance, etc.

Description

(1) Technical field [0001] The invention relates to a disperse dye composition and a disperse dye. (2) Background technology [0002] With the rapid development of new polyester fibers in recent years and the increase in people's demand for textiles, correspondingly, higher requirements have been put forward for the dyeing performance and environmental protection performance of the dye itself, requiring the dye to have high lifting power and various dyeing properties. fastness. In this regard, how to use compound synergistic means to develop new dyes, especially the widely used blue-black dyes, has become the focus of experts in the industry. However, from the existing compound dyes such as patents JP2005-036071, According to the formula dyes provided by US2004339252, JP11-158402, US6562082, etc., they still cannot fully meet the requirements in terms of application properties such as lifting power and color fastness. (3) Contents of the invention [0003] The purpose of...
