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 invention discloses a disperse dye composition. The disperse dye composition comprises a component A, a component B and a component C, wherein 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 byformula (III) and / or formula (IV). The disperse dye composition has the characteristics of excellent sublimation resistance, excellent friction resistance and excellent color fastness to washing whenapplied to printing and dyeing of polyester and blend fiber materials thereof.

Description

[0001] (1) Technical field [0002] The invention relates to a disperse dye composition and its dye product, and the application of the dye product on hydrophobic fiber materials, especially the application of polyester and its blended fabric dyeing or printing. [0003] (2) Background 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 general disperse dyes have high affinity for spandex and good dyeability, resulting in serious contamination of spandex with disperse dyes. During the fastness test, the disperse dyes stained on the 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 moderat...
