Problems solved by technology

Among them, disperse black azo dyes are widely used, but single-component disperse black dyes often have disadvantages such as deep dyeing, insufficient lifting power, and poor fastness. Especially when used for fabric printing, it will cause serious staining on white backgrounds.
[0003] There are U.S. Patent US6159249, Korean Patent KR0156834, KR95029349, KR2000060609, Taiwan Patent TW444047B, Chinese Patent CN100503740C, Chinese Patent CN1113941C and Chinese Patent CN1304490C etc. about the publicly reported method of performance improvement, wherein the technical scheme adopted is a group of azo dyes Compounding, the application performance of the obtained composite disperse black dye has been improved, but there is still the disadvantage of poor level dyeing

Embodiment 1

[0064] Add 15.1 g of dye of formula (Ib), 13.2 g of dye of formula (IIa), 14.8 g of dye of formula (IIIa), 6.9 g of dye of formula (Va), 50 g of sodium lignosulfonate, and 300 ml of water After mixing, use a grinder to grind and disperse, and spray dry (inlet temperature is 130°C, outlet temperature is 60°C) to obtain 100 grams of finished product. 0.4g of this product was dyed for 10g of polyester fiber at pH 4.5 and 130°C for 60 minutes, and then washed, rinsed, and dried to obtain bright black dyed products with excellent fastness properties.

[0065]

Embodiment 2

[0067] Add 11.2 g of dye of formula (Ib), 11.3 g of dye of formula (IIa), 13.5 g of dye of formula (IIIa), 6 g of dye of formula (Va), 98 g of sodium lignosulfonate, and 450 ml of water After mixing, the dye mixture was prepared according to the method of Example 1, and then the polyester fiber was dyed according to the method of Example 1 to obtain bright black dyed products with excellent fastness properties. .

Embodiment 3

[0069] After mixing 5.2 g of the dye of formula (Ia), 9.8 g of the dye of formula (IIb), and 10 g of sodium lignosulfonate, adding 75 ml of water, the mixture was ground and dispersed with a grinder to obtain an aqueous dye product. One gram of the product was dyed with 10 grams of polyester fiber according to the method of Example 1, to obtain a bright navy blue dyed product with excellent washing and various fastness properties.

Abstract

The invention discloses a disperse black azo dye mixture. The product comprises at least one of the compound shown by a formula (I) and a compound shown by a formula (II), wherein a substituent group in the formula is defined in the specification part. Micro-particlized liquid-state dried powder and particle can be provided for dyeing. When the dye provided by the invention is used for printing and dyeing a polyester fiber material, a deep black dyed fabric with superior performances such as beautiful color, high levelling property and dispersion, sun proofing, wash resistance and perspiration resistance can be achieved by adjusting the proportion of different components.

Description

One technical field [0001] The invention relates to a dispersed black azo dye mixture and a preparation method thereof, and belongs to the technical field of chemical material preparation. 2. Background technology [0002] Disperse azo dyes (a class of organic compounds with aryl groups connected at both ends of the azo group) are the most widely used synthetic dyes in the printing and dyeing process of textiles and clothing, and are used for dyeing and printing a variety of natural and synthetic fibers. , Also used for coloring paint, plastic, rubber, etc. Such dyes have the advantages of bright colors, excellent fastness, and a wide variety of colors. Among them, disperse black azo dyes are very versatile, but single-component disperse black dyes often have disadvantages such as deep dyeing, insufficient lifting power, and poor fastness. Especially when used in fabric printing, they will cause serious staining on the white background. . [0003] There are US patents US6159249,...
