Embodiment 1

[0041] A black disperse dye mixture, composed of component A shown in structural formula (I), component B shown in structural formula (II-1), component C shown in structural formula (III-1), structural formula (IV-1 ) shown in component D, component E shown in structural formula (Ⅴ) and auxiliary agent composition:

[0042]

[0043] In terms of mass fraction, the mass fraction of component A is 6%, the mass fraction of component B is 27%, the mass fraction of component C is 3%, the mass fraction of component D is 3.5%, and the mass fraction of component E The fraction is 9%, and the rest are additives.

[0044] The preparation method of the black disperse dye mixture is as follows: after mixing the components A to E according to the preset ratio, in the presence of auxiliary agents (43.5% dispersant MF, 8% moisture), use a sand mill or grind The black disperse dye mixture is obtained by micronizing with a pulverizing device such as a machine.

Embodiment 2

[0046] Adopt the method identical with embodiment 1 to prepare black disperse dye mixture, but choose the dyestuff with following structural formula as component B:

[0047]

Abstract

The invention discloses a dark blue to black disperse dye mixture. The dark blue to black disperse dye mixture is composed of a component A shown in a structural formula (I), a component B shown in a structural formula (II), a component C shown in a structural formula (III), a component D shown in a structural formula (IV), a component E shown in a structural formula (V), and an auxiliary agent. The dye mixture comprises the following components by mass fraction: 2-30% of the component A, 15-45% of the component B, 1-10% of the component C, 1-10% of the component D, 2-15% of the component E, and the balance of the auxiliary agent. The cloth samples dyed by the dark blue to black disperse dye mixture is brilliant, and has the advantages of excellent fastness to washing, antifriction fastness, fastness to perspiration, fastness to light, and degree of dyeing.

Description

technical field [0001] The invention relates to a disperse dye, in particular to a dark blue to black disperse 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. [0004] For example, the Chinese patent document whose...
