Technical Field

The invention belongs to the technical field of dyeing, and particularly relates to a high-wet-fastness fast disperse dye.

Background

The disperse dye is the variety with the highest yield and the largest usage amount in all the dye varieties in China, because the application object of the disperse dye is the polyester fiber, and the polyester fiber firstly draws the first direction in the usage amount of the fiber for people in China to take. The disperse dye is a water-soluble dye, and the production of the disperse dye is different from other dyes, and needs two stages, namely, the synthesis of the primary dye, the primary dye is a chemical main body of the dye, and the disperse dye cannot be directly used for dyeing polyester fabrics. And secondly, the commercial processing of the raw dye, namely the raw dye can be changed into the commercial dye only by adding different processing aids according to different application requirements and carrying out different processing, but the existing disperse dye has low dispersion speed in water and is not firm in dyeing at present.

Disclosure of Invention

In order to solve the problems, the invention provides the high-wet-fastness fast disperse dye which has the advantages of good product stability, long-term storage, good affinity with water, easy redispersion in water, good dyeing performance and difficult separation from polyester fibers after dyeing.

In order to realize the functions, the technical scheme adopted by the invention is as follows: a high wet fastness fast disperse dye comprises the following components in parts by weight: 40-60 parts of distilled water, 15-20 parts of a dispersing agent, 11-15 parts of acrylic dye, 2-4 parts of lauroyl peroxide, 2-5 parts of potassium bicarbonate, 2-4 parts of an emulsifier, 1-3 parts of a modifier, 3-5 parts of hydroxypropyl methyl cellulose and 22-43 parts of toluene.
