Embodiment 1

[0043] A disperse black dye mixture, composed of component A shown in structural formula (I-1), component B shown in structural formula (II-1), component C shown in structural formula (III), structural formula (IV-1 ) shown in component D, component E shown in structural formula (Ⅴ-1) and dispersant and moisture composition:

[0044]

[0045] In mass fraction, the mass fraction of component A is 4%, the mass fraction of component B is 3%, the mass fraction of component C is 4%, the mass fraction of component D is 4%, the mass fraction of component E is The fraction is 30%, the mass fraction of component F is 1%, and the others are auxiliary agents.

[0046] The preparation method of the disperse black dye mixture is: after mixing the components A to F according to the preset ratio, use a sand mill or The dye mixture is obtained by micronizing using a pulverizing device such as a grinder.

Embodiment 2

[0048] Adopt the method identical with embodiment 1 to prepare disperse black dye mixture, but choose the dyestuff with following structural formula as component A:

[0049]

[0050] The amount of each component was not changed.

Abstract

The invention discloses a disperse black dye mixture. The mixture comprises, by mass, 1-10% of a component A represented by structural formula (I), 1-10% of a component B represented by structural formula (II), 1-10% of a component C represented by structural formula (III), 1-10% of a component D represented by structural formula (IV), 15-40% of a component E represented by structural formula (V), 0-5% of a component F represented by structural formula (VI), and the balance of an assistant. The dye mixture obtained the invention allows a sample cloth dyed by using the mixture to have brilliant color, and has the advantages of excellent color fastness and dyeing degree, and low production cost.

Description

technical field [0001] The invention relates to a disperse dye, in particular to a disperse black dye mixture. Background technique [0002] After entering the 21st century, the competition in the world's textile market has become increasingly fierce. Southeast Asia's economy has become synonymous with low cost and high growth, and the textile industry business in Europe and the United States has also accelerated its transfer to Asia. In order to adapt to the situation of fierce competition in the textile market, it has become the common goal of textile enterprises to continuously reduce the production cost of textiles, continuously improve product quality, and continuously reduce environmental loads. [0003] Disperse dyes have very low solubility in water, very fine particles, and are dispersed in the dye solution. They are non-ionic dyes and are mainly used for polyester dyeing with high color fastness. For example, the Chinese patent with the publication number CN101760...
