Example Embodiment

[0066] Example 1

[0067] 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.

[0069] Example 2

[0070] 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 add 450 ml of water After mixing, the dye mixture was prepared according to the method of Example 1, and then 10 grams of polyester fiber was dyed according to the method of Example 1, to obtain bright black dyed products with excellent fastness properties.

Example Embodiment

[0071] Example 3

[0072] 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 dispersed black azo dye mixture. The product at least contains a compound of the following formula (I) and at least one of a compound of the following formula (II); and a substituting radical in the formula is as defined in the specification. The dispersed black azo dye mixture can be used for dyeing micro-particle liquid state, dried power and grain state. When the dye disclosed by the invention is used for dyeing a polyester fiber material, a deep dark dyed texture with good performances of full color and cluster, good uniform dyeing performance and dispersity, sun resistance, washing resistance, sweat resistance and the like can be obtained through adjusting the ratios of different components.

Description

a technical field [0001] The invention relates to a disperse black azo dye mixture and a preparation method thereof, belonging to the technical field of chemical material preparation. Two background technology [0002] Dispersed azo dyes (English name: azo dyes) refer to a class of organic compounds that are connected to aryl groups at both ends of the azo group. and printing. This type of dye has the advantages of bright color, excellent fastness, and a wide variety of colors. 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. .
