Embodiment 1

[0032] Example 1:

[0033] With the dyestuff A of 20g formula (I-1), the dyestuff B of 19g formula (II-1) and (II-2), the dyestuff C of 6g formula (III-1), the dispersant MF of 40g, add water after mixing , grind and disperse with a grinder, and spray dry to obtain the dye product 1. The dye provides a uniform black color to the fabric with good fastness properties.

Embodiment 2

[0035] After mixing 20g of dye A of formula (I-1), 25g of dye B of formula (II-1) and (II-2), 40g of dispersant MF with water, grind and disperse with a grinder, and spray dry, that is Dye preparation 2 was obtained which provided a uniform indigo color to the fabric with good fastness properties.

Embodiment 3

[0037] With the dyestuff A of 20g formula (I-2), the dyestuff B of 20g formula (II-2), the dyestuff C of 5g formula (III-1), the dispersant lignin of 40g, after adding water and mixing, grind with grinder Disperse and spray dry to obtain the dye product 3.

Abstract

The invention relates to the disperse dye technology field, and provides a dark disperse dye composition and applications to overcome defects that types of dark disperse dyes with single structures are not many, the deep dyeing property and elevating power are insufficient and the fastness performance is poor in present disperse dyes. The composition is composed of, by weight, 5-95 parts of dye A, 5-95 parts of dye B and 0-35 parts of dye C. The composition has excellent dyeing performances.

Description

technical field [0001] The invention relates to the technical field of disperse dyes, in particular to a dark disperse dye composition and its application. Background technique [0002] Recently, with the development of polyester, polyester fiber and their blended fabrics, the performance requirements of disperse dyes are also getting higher and higher. Among the existing conventional disperse dyes, there are not many varieties of dark disperse dyes with a single structure, and these dyes often have the disadvantages of insufficient dyeing depth, insufficient lifting power, and poor fastness performance, and the development of new structures of disperse dyes is relatively slow. , so it is more and more important to commercialize existing products. Generally, in the dyeing process, heat setting process or other finishing processes of dark disperse dyes, due to the poor dyeing performance of the dye itself, it is necessary to find more disperse dye mixtures with excellent dye...
