Example Embodiment

[0064] Example 1

[0065] 14.9 g of the dye of formula (Ia) 10.1 g of sodium lignosulfonate was mixed with 75 ml of water, and then ground and dispersed with a grinder to obtain an aqueous dye product. 1.0 g of this product was dyed with 10.0 g of polyester fiber at pH 4.5 and 130°C for 60 minutes, and then washed, rinsed, and dried to obtain a bright navy blue dyed product with excellent washing and various fastness properties.

[0066]

Example Embodiment

[0067] Example 2

[0068] Add 15.0 g of the dye of formula (Ib), 13.2 g of the dye of formula (IIa), 15.0 g of the dye of formula (IIIa), 6.8 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 with 10.0g of polyester fiber at pH 4.5 and 130°C for 60 minutes, then washed, rinsed, and dried to obtain bright black dyed products with excellent fastness properties.

[0069]

[0070]

Example Embodiment

[0071] Example 3

[0072] Add 11.5 g of the dye of formula (Ib), 11.2 g of the dye of formula (IIa), 13.5 g of the dye of formula (IIIa), 5.8 g of dye of formula (Va), 98 g of sodium lignosulfonate to 450 ml of water After mixing, the dye mixture was prepared according to the method of Example 2, and then the polyester fiber was dyed according to the method of Example 2 to obtain bright black dyed products with excellent fastness properties. .

Abstract

The invention discloses a dispersing azo dye mixture. The dispersing azo dye mixture at least contains a compound of the following formula (I), and a substituent group in the formula is defined in an instruction portion. The dispersing azo dye mixture can supply dye in the form of fine particalization liquids, dried powders and particles. When the dispersing azo dye mixture is used for dyeing polyester fiber materials, pitch black dyed fabrics which have good performances of being gorgeous in color and luster, good in level dyeing property and dispersing property, sun-proof, washable, perspiration-proof and the like can be obtained by adjusting ratios of different components.

Description

A technical field [0001] The invention relates to a dispersed azo dye mixture and a preparation method thereof, belonging to the technical field of chemical material preparation. Two background technology [0002] Dispersed azo dyes (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. They are used for dyeing and dyeing of various natural and synthetic fibers. Printing, also used for coloring of paint, plastic, rubber, etc. This type of dye has the advantages of bright color, excellent fastness, and a wide variety of colors. Disperse-type azo dyes are widely used, but single-component disperse-type azo dyes often have disadvantages such as deep dyeing, insufficient lifting power, and poor fastness, especially when used for fabric printing, which will cause white background staining serious. [0003] The publicly reported methods...
