Abstract

The invention discloses a dark blue-dark disperse dye composition with high dyeing rate, wherein the dye composition is composed of a component A shown in a structural formula (I), a component B shown in structural formula (II), a component C shown in structural formula (III), a component D shown in structural formula (IV), a component E shown in structural formula (V), a component F shown in structural formula (VI) and an assistant; according to the mass percent, the pass percent of the component A is 1-15%, the pass percent of the component B is 10-45%, the pass percent of the component C is 1-10%, the pass percent of the component D is 1-10%, the pass percent of the component E is 1-10%, and the pass percent of the component F is 1-10%; the rest is assistant. The sample cloth dyed by the dye composition has bright color and light, and is excellent in fastness to washing, fastness to rubbing, perspiration fastness, fastness to sun and degree of dyeing.

Description

technical field [0001] The invention relates to a disperse dye, in particular to a deep blue to black disperse dye composition with high color yield. Background technique [0002] After entering the 21st century, the competition in the world's textile market has become increasingly fierce. Southeast Asia's economy has become synonymous with low cost and high growth, and the textile industry business in Europe and the United States has also accelerated its transfer to Asia. In order to adapt to the situation of fierce competition in the textile market, it has become the common goal of textile enterprises to continuously reduce the production cost of textiles, continuously improve product quality, and continuously reduce environmental loads. [0003] Disperse dyes have very low solubility in water, very fine particles, and are dispersed in the dye solution. They are non-ionic dyes and are mainly used for polyester dyeing with high color fastness. [0004] For example, the Chi...
