Technical Field

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

Background

Most common disperse dyes in the current market 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 polyurethane blended fabrics are used, the fastness is very poor, and the fastness is not greatly improved even by multiple reduction washing (the reduction washing mode comprises two types, namely alkali washing, adding sodium hydrosulfite and caustic soda flakes, and acid washing, adding acid reduction washing agent and acetic acid), so the requirements of high-end orders cannot be met!

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the disperse violet dye has high fastness and good dyeing performance, and the color fastness of the dyed disperse violet dye can reach more than 4 levels in the 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 violet dye comprises the following components in parts by weight: 15-25 parts of a component B: 25-35 parts of component C: 5-10 parts, component D: 10-18 parts, component E: 7-15 parts, component F: 3-10 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:and/or

The component E is as follows:

mixtures in any ratio;

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

Preferably, the high-fastness disperse violet dye comprises the following components in parts by weight: and (2) component A: 20-25 parts of component B: 25-30 parts of component C: 5-8 parts of a component D: 12-16 parts of a component E: 10-15 parts, component F: 5-10 parts.
