Problems solved by technology

[0004] With the development of polyester and its blended fabrics, especially in recent years, spandex-containing elastic fabrics are very popular in domestic and foreign markets. Static electricity, the fabric is mainly dyed with disperse dyes, but the general disperse dyes have high affinity for spandex and good dyeability, resulting in serious contamination of spandex by disperse dyes
During the fastness test, the disperse dyes stained on spandex can easily migrate out of the fiber, affecting the wet fastness of polyester / spandex textiles
Many disperse dyes have good color fastness to rubbing, washing and light on polyester, but the fastness to spandex can only reach a moderate level, so that products with high color fastness requirements have a large problem in the dyeing process. The problem

Abstract

The present invention discloses a disperse dark blue to black 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 formula (I), the component B is selected from at least one of compounds represented by formula (II), and the component C is selected from at least one of compounds represented by formula (III). The disperse dark blue to black dye composition provided by the invention has the characteristics of excellent friction resistance, washing resistance, sublimation fastness and the like when being applied to dyeing of hydrophobic fiber materials.

Description

[0001] (1) Technical field [0002] The invention relates to a disperse dark blue to black dye composition and its dye product, as well as the application of the dye product on hydrophobic fiber materials, especially the application in the dyeing of polyester and its blended fabrics.
