Problems solved by technology

Conventional disperse dark blue and disperse black, such as disperse blue ECO, disperse black ECT, and disperse black S-4BL, although the price is relatively low, but the improvement is average. For orders with high blackness requirements, the amount of dye will increase, and the amount of production sewage will increase. Large, resulting in an increase in sewage treatment costs, adverse effects on environmental protection, and the color fastness can not meet the requirements

Embodiment 1

[0059] With 10 grams of formula (I-2) compound, 40 grams of formula (II-3) compound, 20 grams of formula (III-1) compound, 30 grams of formula (IV-1) compound, 280 grams of dispersant MF, add 1000 After blending with gram water, grinding and dispersing, and spray drying, the finished product can be obtained, and the finished product can provide black tone of polyester and its blended fabrics.

[0060]

Embodiment 2

[0062] With 15 grams of formula (I-2) compound, 60 grams of formula (II-4) compound, 10 grams of formula (III-2) compound, 15 grams of formula (IV-1) compound, 250 grams of dispersant MF, add 1000 After blending with gram water, grind and disperse, spray dry to obtain the finished product, which can provide navy blue hue for polyester and its blended fabrics.

[0063]

Embodiment 3～28

[0065] According to the method described in embodiment 1-2, the difference is to adopt the structure and weight of component A, component B, component C and component D in table 1, add 200 grams of auxiliary agents (dispersant MF is 150 grams , sodium lignosulfonate is 50 grams), add 1200 grams of water and blend to make a slurry, grind and disperse, dry, and make a finished product. This dye can provide polyester and its blended fabrics with various fastness performances. Black tones.

Abstract

The invention discloses a disperse blue-to-black dye composition and a dye product thereof. The disperse blue-to-black dye composition comprises a component A, a component B, a component C and a component D, wherein the component A is selected from one or more of compounds shown in a formula (I), the component B is selected from one or more of compounds shown in a formula (II), the component C isselected from one or more of compounds shown in a formula (III), and the component D is selected from one or more of compounds shown in a formula (IV). The invention provides a disperse blue-to-blackdye product, which contains the disperse blue-to-black dye composition and an auxiliary agent, and the weight ratio of the auxiliary agent to the disperse dye composition is 0.2-5:1. When the dye product is applied to dyeing or printing of a hydrophobic fiber material, the dye product has the characteristics of good lifting power, excellent color fastness and the like.

Description

[0001] (1) Technical field [0002] The invention relates to a disperse blue to black dye composition and a dye product, in particular to a disperse blue to black dye composition and a dye product suitable for hydrophobic fiber materials and blended fabrics thereof. [0003] (2) Background technology [0004] Blue-black series disperse dyes are the most widely used varieties in polyester fiber and fabric dyeing. Conventional disperse dark blue and disperse black, such as disperse blue ECO, disperse black ECT, and disperse black S-4BL, although the price is relatively low, but the improvement is average. For orders with high blackness requirements, the amount of dye will increase, and the amount of production sewage will increase. Large, resulting in an increase in the cost of sewage treatment, adverse effects on environmental protection, and the color fastness can not meet the requirements. As people's requirements for textile products are getting higher and higher, disperse d...
