A kind of dye composition, disperse dye product containing it and application thereof

Abstract

The invention discloses a disperse dye composition. The composition is composed of a compound A and a compound B, and a general formula (I) of the compound A and a general formula (I) of the compoundB are as shown in the specification. The invention further discloses a disperse dye product comprising the disperse dye composition, and a mass ratio of the compound A to the compound B in the disperse dye composition is (90:10)-(10:90). The disperse dye product further comprises one or more of a conventional dye, a dispersing agent and an auxiliary agent, a mass ratio of the conventional dye to the composition is (5:95)-(90:10), a mass ratio of the dispersing agent to the composition is (20:80)-(80:20), and a mass ratio of the auxiliary agent to the composition is (1:1000)-(3:100). The invention further discloses application of the disperse dye product to fiber products, especially application to polyester and blended products of polyester and cotton, acrylic fibers, wool, cellulose acetate fibers and nylon.

Description

technical field [0001] The invention belongs to the field of printing and dyeing, and specifically relates to a dye composition, a disperse dye product containing the same and an application thereof. Background technique [0002] At present, the use of disperse dyes in the printing and dyeing industry is large, and there are many varieties. Among them, azo and anthraquinone are the main two types of disperse dyes. Although azo disperse dyes are mostly not as bright as anthraquinone disperse dyes, it is well known that the production of anthraquinone dyes has the disadvantages of heavy pollution and high cost. Although the market has a strong demand for bright blue dyes, the high cost and heavy pollution of disperse dyes are always the key constraints to the application and promotion of disperse dyes. Therefore, how to improve the printing and dyeing properties of azo-based disperse dyes has become a research hotspot for those skilled in the art. [0003] Existing studies h...

Problems solved by technology

[0006] The disperse dye is dark blue, bright shade, but poor dyeing performance

And because the ester group at the end of the dye is easily hydrolyzed to form a water-soluble carboxyl group, C.I. Disperse Blue 148 is more sensitive to the pH value of the working system when dyeing, so the conditions for the printing and dyeing process using this dye are more stringent
