Embodiment 1

[0041] A black disperse dye mixture with high coloring rate, 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), Component D shown in structural formula (IV-1), component E shown in structural formula (V), component F shown in structural formula (VI) and auxiliary agent composition:

[0042]

[0043] In terms of mass fraction, the mass fraction of component A is 2.5%, the mass fraction of component B is 28%, the mass fraction of component C is 4%, the mass fraction of component D is 3%, and the mass fraction of component E The fraction is 8%, the mass fraction of the component F is 5%, and the rest are auxiliary agents.

[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 (41.5% dispersant MF, 8% moisture), use a sand mill or grind The black dis...

Abstract

The invention discloses a dark blue to black disperse dye mixture with a high dyeing degree. The mixture is composed of the following components in percentage by weight: 1 to 10% of component A represented by the structural formula (I), 10 to 45% of component B represented by the structural formula (II), 1 to 10% of component C represented by the structural formula (III), 1 to 10% of component D represented by the structural formula (IV), 1 to 15% of component E represented by the structural formula (V), 1 to 10% of component F, and the balance being auxiliary agents. The sample cloth dyed by the provided mixture has a bright color and excellent fastness to washing, fastness to rubbing, fastness to perspiration, fastness to sublimation, and dyeing degree.

Description

technical field [0001] The invention relates to a disperse dye, in particular to a dark blue to black disperse dye mixture with high color yield. 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...
