Problems solved by technology

Among the existing conventional disperse dyes, there are few blue-black disperse dyes with a single structure, and these dyes often have the disadvantages of insufficient dyeing depth, insufficient lifting power, and poor fastness performance. Therefore, a single blue-black disperse dye is generally not used for dyeing. , Usually, dyes of different structure types and colors are blended to prepare black disperse dyes
The traditional black and blue dyes blended by C.I. Disperse Blue 291:1, C.I. Disperse Violet 93, and C.I. Disperse Orange 76 are the most widely used,

Embodiment 1

[0063] Mix 60 parts of dye A of formula (I-1), 25 parts of dye B of formula (II-1) and 15 parts of formula (II-2), 125 parts of dispersant MF, add 600 parts of water, and grind After dispersing and drying, the finished product is obtained. This dye is suitable for dyeing polyester fiber and its blended fabrics, and can provide navy blue with uniform and good fastness properties to the fabric.

Embodiment 2

[0065] Mix 26 parts of dye A of formula (I-1) and 14 parts of formula (I-2), 60 parts of dye B of formula (II-2), 150 parts of dispersant MF, add 600 parts of water, grind and disperse , dry, and the finished product is obtained. The dye is suitable for dyeing polyester fiber and its blended fabrics, and can provide dark blue fabrics with uniform and good fastness properties.

Embodiment 3

[0067] With 28 parts of dye A of formula (I-1), 31 parts of formula (II-1) and 28 parts of dye B of formula (II-2), 5 parts of formula (III-1) and 5 parts of formula (III-2) Dye C of formula (IV-1) and 2 parts of dye D of formula (V-1), 125 parts of dispersant MF, mixed with 600 parts of water, ground and dispersed, dried to obtain the finished product, the dye It is suitable for dyeing polyester fiber and its blended fabrics, and can provide uniform navy blue color with good fastness performance.

Abstract

The invention provides a dispersed dark dye composition, which mainly comprises 5-95 parts by mass of one or more dye components A shown in formula (I) and 5-95 parts by mass of one or more dye components B shown in formula (2). When applied to a hydrophobic textile material, in particular to polyester material embossing or coloration, the dispersed dark dye composition provided by the invention has the characteristics of good dyeing depth, excellent lifting capacity, good color fastness and the like, therefore, the dye consumption during coloring is small, and the use cost of the dye is favorably saved.

Description

(1) Technical field [0001] The invention relates to a dark disperse dye composition, in particular to a disperse dye composition suitable for dyeing hydrophobic fiber materials such as polyester fiber materials and blended fabrics thereof. (2) Background technology [0002] With the development of polyester hydrophobic fiber materials and their blended fabrics, and the improvement of ecological and safety performance requirements for textile printing and dyeing products, ordinary disperse dyes can no longer meet their dyeing needs during printing and dyeing, such as serious contamination of other fibers during dyeing. , causing the overall color fastness of the fabric to decrease, and the stains are not easy to remove and other problems. In addition, due to the slow development of new structures of disperse dyes, it is increasingly important to commercialize existing products. Among the existing conventional disperse dyes, there are few blue-black disperse dyes with a singl...
