Disperse dye mixture and application thereof

Abstract

The invention relates to the technical field of dyes. To overcome the problems that anthraquinone disperse dyes have excellent light fastness but poor fastness to washing and rubbing and that azo disperse dyes which have good fastness to washing and rubbing generally have inadequate light fastness, the invention brings forward a disperse dye mixture which is prepared by mixing the four components of dye A, dye B, dye C and dye D, wherein dye A accounts for 1 to 20 parts by weight, dye B accounts for 10 to 90 parts by weight, dye C accounts for 1 to 20 parts by weight and dye D accounts for 10 to 50 parts by weight. The disperse dye mixture and products thereof provided in the invention have satisfactory fastness to washing and rubbing and excellent light fastness, which enables the problem that a product of a same kind does not have both good fastness to washing and rubbing and excellent light fastness to be overcome.

Description

technical field [0001] The invention relates to the technical field of dyes, in particular to a blue disperse azo dye mixture and its application. Background technique [0002] In recent years, the application range of fiber materials in people's life has been continuously expanding. Different temperature, humidity, sunlight intensity and frequency of use require that disperse dyes for fiber material dyeing have a wide range of application and superior dyeing performance. At present, the widely used disperse dyes are mostly anthraquinone and azo disperse dyes, but these two types of disperse dyes have defects in the process of use. However, the washing and rubbing fastnesses are poor, and the azo disperse dyes with good washing and rubbing fastnesses generally have unsatisfactory light fastness. [0003] The application number is that the Chinese patent of 200610154915.3 discloses a kind of disperse blue dye composition, and this invention basically consists of one or more ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that anthraquinone disperse dyes in disperse dyes are outstanding in light fastness, but their washing and rubbing fastness are poor, while azo disperse dyes with good washing and rubbing fastness are generally exposed to light The problem of unsatisfactory fastness, the present invention proposes a disperse dye mixture, the disperse dye mixture of the present invention and its products not only have satisfactory washing and rubbing fastness, but also have excellent light fastness, solve Solved the problem that the two products of the same kind could not take into account
