A kind of dark disperse dye composition

Abstract

The invention relates to a deep-color disperse dye composition. In order to solve the problems that the molecular attraction between a dye and an ultrafine denier fiber is greatly reduced, the dyeing rate of the dye is greatly reduced, the fastnesses on all the aspects of a dyed fabric are reduced to different extents, and particularly, the influence on the washing fastness is most remarkable because the dyeing performance of a common deep-color disperse dye is not good, the invention provides the deep-color disperse dye composition which contains the following components in parts by weight: 5-95 parts of one or more dye components A as shown in the formula (I) and 5-95 parts of one or more dye components B as shown in the formula (II). The invention provides the economic disperse dye composition which has good washing fastness on a polyester fiber and polyester blended fabric.

Description

technical field [0001] The invention relates to a dark disperse dye composition, in particular to a disperse dye composition suitable for dyeing polyester, polyester fiber and other fabrics. Background technique [0002] At present, with the development of polyester, polyester fiber and its blended fabrics, especially the development of superfine fiber and superfine denier fiber, the performance requirements of disperse dyes are also getting higher and higher. For general dark disperse dyes, due to the poor dyeing performance of the dye itself, the molecular attraction between the dye and the ultra-fine denier fiber is greatly reduced, the dye uptake rate of the dye is greatly reduced, and the fastness of the dyed fabrics in all aspects decreases to varying degrees. , especially the impact on washing fastness is the most obvious. Therefore, develop a kind of disperse dye that has good lifting power and fastness performance, especially on fabrics such as superfine fiber, sup...

Problems solved by technology

[0003] In order to solve the general dark disperse dyes, due to the poor dyeing performance of the dye itself, the molecular attraction between the dye and the ultra-fine denier fiber is greatly reduced, the dye uptake rate of the dye is greatly reduced, and the fastness of all aspects of the dyed fabric has different degrees. In particular, the impact of washing fastness is the most obvious problem. The present invention proposes a dark color disperse dye composition, which provides an economical disperse dye with good washing fastness on polyester fibers and polyester blended fabrics. dye composition
