Embodiment 1

[0063] With the dyestuff of 13.3 grams of formula (Ia), 11 grams of dyestuff of formula (IIa), the dyestuff of 13.7 grams of formula (IIIa), the dyestuff of 6 grams of formula (Va), the sodium lignosulfonate of 44 grams, add 300 milliliters of water After mixing, grind and disperse with a grinder, spray dry (inlet temperature 130° C., outlet temperature 60° C.) to obtain 100 grams of finished product. 0.4 gram of this product was dyed at pH 4.5 and 130°C to 10 gram of polyester fiber for 60 minutes, then washed, rinsed and dried to obtain a bright black dyed product with excellent fastness properties.

[0064]

Embodiment 2

[0066] With the dyestuff of 12 grams formula (Ia), the dyestuff of 11 grams formula (IIa), the dyestuff of 13 grams formula (IIIa), the dyestuff of 6 grams formula (Va), the sodium lignosulfonate of 98 grams, add 300 milliliters of water After mixing, the dye mixture was prepared according to the method of Example 1.

Embodiment 3

[0068] After mixing 5 grams of the dye of formula (Ia), 10 grams of the dye of formula (IIb), and 10 grams of sodium lignosulfonate with 75 milliliters of water, grind and disperse with a grinder to obtain a water-containing dye product. 1 gram of this product is dyed according to the embodiment 1 method to 10 gram of polyester fiber, obtains the dyed product of the bright navy blue that has excellent washing and each fastness performance.

Abstract

The invention discloses a dispersed azo dye mixture, which contains a compound shown as at least one formula (1) and a compound shown as at least one formula (II), wherein substituent groups in the formulas are defined in the specification. The dispersed azo dye mixture can be used for dyeing by micronized liquid and dried powder and granules. When polyester fiber materials are subjected to printing and dyeing by the dye, dark black dyed fabrics which are gorgeous in color and luster, high in level-dyeing property and dispersibility, sunproof, washable, resistant to perspiration and the like can be obtained by adjusting ratios of different components.

Description

a technical field [0001] The invention relates to a disperse azo dye mixture and a preparation method thereof, belonging to the technical field of chemical material preparation. Two background technology [0002] Azo dyes (azo dyes, a class of organic compounds connected to aryl groups 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 of various natural and synthetic fibers. It is also used for the coloring of paint, plastic, rubber, etc. Azo dyes have the advantages of bright colors, excellent fastness, and a wide variety of colors. Among them, black azo disperse 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 the white background. . [0003] There are U.S. Patent US6159249...
