Technical Field

The invention relates to the field of preparation of disperse dye compositions, in particular to a high-fastness disperse yellow dye.

Background

With the rapid development of new polyester fibers and the improvement of requirements of people on textiles in recent years, correspondingly, higher requirements on the dyeing performance and the environmental protection performance of dyes are also provided. The dye is required to have high lifting power and various dyeing fastness, and also has good environmental protection performance so as to avoid environmental pollution.

Most of common disperse dyes in the market at present are conventional dyes, the fastness of the disperse dyes on 100 percent of common terylene is still good, but the disperse dyes are completely not good when superfine fibers or terylene and spandex blended fabrics are used, the fastness is very poor, and the fastness is not greatly improved even by multiple reduction washing (two reduction washing modes, namely alkali washing, adding sodium hydrosulfite and caustic soda flakes, and acid washing, adding acid reduction washing agent and acetic acid) cannot meet the requirements of high-end orders.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the high-fastness disperse yellow dye is good in dyeing performance, and the color fastness of the dyed disperse yellow dye can reach 4-5 levels in a polyester superfine fiber and polyester spandex blended fabric.

In order to solve the technical problems, the invention adopts the technical scheme that: a high-fastness disperse yellow dye comprises the following components in parts by weight: and (2) component A: 15-25 parts of a component B: 20-27 parts of component C: 5-8 parts of a component D: 10-15 parts, component E: 8-15 parts, component F: 8-10 parts;

the component A is as follows:

the component B is as follows:

the component C is as follows:

the component D is as follows:

the component E is as follows:

the component F is 2-naphthalene sulfonic acid formaldehyde polymer sodium salt.

Preferably, the high-fastness disperse yellow dye comprises the following components in parts by weight: and (2) component A: 15-20 parts of component B: 20-25 parts of component C: 5-6 parts, component D: 12-14 parts, component E: 10-12 parts of a component F: 8-9 parts.
