Abstract

The invention discloses a high-performance polyazo green reactive dye. The reactive dye contains polyazo dye shown in a formula I and is applied to cellulose fibers such as cotton and hemp and protein fibers such as wool and silk for dip dyeing, continuous dyeing and textile printing. The high-performance polyazo green reactive dye is green, has relatively high dye uptake and fixation rate and meanwhile has very high wet fastness such as wash well and perspiration resistance as well as light fastness. As the high-performance polyazo green reactive dye is a monogenetic dye, the monogenetic dyestuff has no disadvantages of poor head and tail and poor side and middle during continuous coloring.

Description

technical field

[0001] The invention relates to the synthesis of reactive polyazo dyes, a mixture of high performance polyazo green reactive dyes and its application. Background technique

[0002] Reactive dyes, also known as reactive dyes. It is named because its structure contains active groups that can chemically react with hydroxyl or amino groups in natural or synthetic cellulose fibers. This kind of dye reacts with the fiber during dyeing to form a covalent bond, so that the fastness indicators of the dye, especially the wet fastness, are improved, and it has been widely developed and applied, becoming the largest for cellulose fiber. Reactive dyes are the second largest class of dyes after disperse dyes.

[0003] With the improvement of living standards, people begin to pay more and more attention to the colors and styles of their usual clothes. As a result, there is more demand for clothes with fuller colors and stronger coloring.

[0004] At present, the dark se...
