Problems solved by technology

Although the black disperse dye mixture made of C.I. Disperse Orange 61 overcomes this problem, its dependence on dyeing conditions and level dyeing are not as good as C.I. Disperse Orange 76 and the cost is higher. In addition, with the development of the economy, suede Velvet fabrics are becoming more and more popular for sofa home textiles, shoe uppers, and car decoration. The use of suede fabrics determines the required properties of dyes, such as higher requirements for dry rubbing fastness and perspiration fastness. Therefore, the developed Novel, environmentally friendly and low-cost dyes suitable for dyeing suede fabrics are an inevitable trend

Abstract

The invention provides a disperse dye composition, a disperse dye and a preparation method and a use thereof. The disperse dye is suitable for superfine fibers and is especially suitable for dyeing and printing suede fabrics.

Description

technical field [0001] The invention relates to a disperse dye composition, a disperse dye and a preparation method and use thereof. The disperse dye is suitable for the dyeing and printing of superfine fibers, especially the dyeing and printing of suede fabrics. Background technique [0002] The traditional black disperse dye mixture made of C.I. Disperse Orange 76 has good levelness and fastness. However, because C.I. Disperse Orange 76 will crack allergenic dyes under certain conditions, it has been banned by various countries. Although the black disperse dye mixture made of C.I. Disperse Orange 61 overcomes this problem, its dependence on dyeing conditions and level dyeing are not as good as C.I. Disperse Orange 76 and the cost is higher. In addition, with the development of the economy, suede Velvet fabrics are becoming more and more popular for sofa home textiles, shoe uppers, and car decoration. The use of suede fabrics determines the required performance of dyes, su...
