Embodiment 1

[0034] A disperse black dye composition with high color fastness, comprising component A shown in structural formula (I-1), component B shown in structural formula (II-1), and component C shown in structural formula (III) , component D shown in structural formula (Ⅳ-1), component E shown in structural formula (Ⅴ) and auxiliary agent composition:

[0035]

[0036] In terms of mass fraction, the mass fraction of component A is 4%, the mass fraction of component B is 5%, the mass fraction of component C is 5%, the mass fraction of component D is 13%, and the mass fraction of component E The fraction is 6%, and the rest are additives.

[0037] The preparation method of the disperse black dye composition is: after mixing the components A to E according to the preset ratio, use a sand mill in the presence of auxiliary agents (59% dispersant MF, 8% water content) or a pulverizing device such as a mill to obtain the dye composition.

Embodiment 2

[0039] Adopt the method identical with embodiment 1 to prepare disperse black dye composition, but choose the dyestuff with following structural formula as component A:

[0040]

[0041] The amount of each component was not changed.

Embodiment 3

[0048] Adopt the method identical with embodiment 2 to prepare disperse black dye composition, but choose the dyestuff with following structural formula respectively as component B:

[0049]

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

Abstract

The invention discloses a dispersed black dye composition with high dye fastness. The dispersed black dye composition consists of the following ingredients in percentage by weight: 1-10% of a component A shown in a structural formula (I), 1-10% of a component B shown in a structural formula (II), 1-10% of a component C shown in a structural formula (III), 3-20% of a component D shown in a structural formula (IV), 2-15% of a component E shown in a structural formula (V) and the balance of an addition agent, The sample cloth which is dyed by the dye composition disclosed by the invention is bright in colored light and is excellent in dye uptake and dye fastness, and the production cost of the dye composition is low.

Description

technical field [0001] The invention relates to a disperse dye, in particular to a disperse black dye composition 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 with th...
