Disperse ruby dye composition and dye product

Abstract

The present invention discloses a disperse ruby dye composition which comprises a component A, a component B and a component C. The component A is selected from at least one of compounds represented by a formula (I), the component B is selected from at least one of compounds represented by a formula (II), and the component C is selected from at least one of compounds represented by a formula (III). When the disperse ruby dye composition is applied to dyeing of hydrophobic fiber materials such as polyester and blended fabrics thereof, each fastness, especially sublimation resistance, washing resistance and water soaking color fastness, is excellent;.

Description

[0001] (1) Technical field [0002] The present invention relates to a kind of disperse ruby ​​dye composition and dye product, especially a kind of disperse ruby ​​dye composition and dye product suitable for printing and dyeing hydrophobic fiber material. [0003] (2) Background technology [0004] The traditional C.I. Disperse Red 167 is a widely used dye with a relatively large amount and occupies a certain market share of the dye. However, when the dye is used alone, the dyeing rate and sublimation fastness are poor, and the pollution to the environment in the textile printing and dyeing process is relatively large, which cannot meet the needs of the export of enterprise products. There are similar domestic patents that solve the dyeing problem of replacing disperse red 167. For example, CN1597790A is to solve the problem of low color development rate of C.I. disperse red 167, but the compatibility of C.I. The color light of C.I. Disperse Red 167 is quite different from t...

AI Technical Summary

Problems solved by technology

However, when the dye is used alone, the coloring rate and sublimation fastness are poor, and the pollution to the environment is relatively large in the textile printing and dyeing process, which cannot meet the needs of enterprises for product export.

There are similar domestic patents that solve the dyeing problem of replacing disperse red 167. For example, CN1597790A is to solve the problem of low color development rate of C.I. disperse red 167, but the compatibility of C.I. The color light of C.I. Disperse Red 167 is quite different from that of C.I. Disperse Red 167; the patent CN101565558A is mainly to solve the problem of abnormal color development of C.I. Disperse Red 167 under alkaline conditions. In this combination, C.I. Disperse Red 153 has poor sublimation fastness and washing fastness. The color shade of the same combination is quite different from C.I. Disperse Red 167, so neither of them can replace C.I. Disperse Red 167 very well.
