Embodiment 1

[0040] A kind of composite disperse black dyestuff of high color fastness, by component A shown in structural formula (I), component B shown in structural formula (II-1), component C shown in structural formula (III), structural formula ( Ⅳ) Component D and additive composition shown in:

[0041]

[0042]In terms of mass fraction, the mass fraction of component A is 4%, the mass fraction of component B is 14%, the mass fraction of component C is 12%, the mass fraction of component D is 23%, and the rest are auxiliary agents.

[0043] The preparation method of the composite disperse black dye is as follows: after mixing the components A to D according to the preset ratio, use a sand mill or The composite disperse black dye is obtained by micronizing with a pulverizing device such as a grinder.

Embodiment 2

[0045] Adopt the method identical with embodiment 1 to prepare composite disperse black dyestuff, but choose the dyestuff with following structural formula as component A:

[0046]

[0047] The amount of each component was not changed.

Abstract

The invention discloses a composite scattered black dye high in color fastness. The composition is composed of a component A represented in structural formula (I), a component B represented in structural formula (II), a component C represented in structural formula (III), a component D represented in structural formula (IV) and auxiliaries. According to the mass percentage, the mass fraction of the component A is 1-10%, the mass fraction of the component B is 5-25%, the mass fraction of the component C is 5-25%, the mass fraction of the component D is 10-40%, and the remainder is the auxiliaries. Sample cloth dyed through the composite scattered black dye is bright in color light and has excellent wash fastness, rub fastness, perspiration fastness, sun-proof fastness and degree of dyeing, and the production cost of the composite scattered black dye is low.

Description

technical field [0001] The invention relates to a disperse dye, in particular to a composite disperse black dye with high color fastness. 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 whose pub...
