Problems solved by technology

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 for performance improvement include U.S. Patent US6159249, Korean Patent KR0156834, KR95029349, KR2000060609, Taiwan Patent TW444047B, Chinese Patent CN100503740C, Chinese Patent CN1113941C and Chinese Patent CN1304490C, etc., wherein the technical scheme adopted is a group of dispersed azo With the compounding of dyes, the application performance of the obtained composite disperse azo dyes has been improved, but there are still disadvantages of poor level dyeing

Embodiment 1

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

[0066]

Embodiment 2

[0068] With the dyestuff of 15.0 grams formula (Ib), the dyestuff of 13.2 grams formula (IIa), the dyestuff of 15.0 grams formula (IIIa), the dyestuff of 6.8 grams formula (Va), the sodium lignosulfonate of 50 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 to 10.0 gram of polyester fiber at pH 4.5 and 130° C. for 60 minutes, then washed, rinsed, and dried to obtain a bright black dyed product with excellent fastness properties.

[0069]

[0070]

Embodiment 3

[0072] With the dyestuff of 11.5 grams of formula (Ib), 11.2 grams of dyestuff of formula (IIa), the dyestuff of 13.5 grams of formula (IIIa), the dyestuff of 5.8 grams of formula (Va), the sodium lignosulfonate of 98 grams, add 450 milliliters 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 a bright black dyed product 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...
