Disperse yellow brown dye composition with high dyeing degree

Abstract

The invention discloses a disperse yellow brown dye composition with a high dyeing degree. The composition comprises, by mass, 5-10% of a component A represented by structural formula (I), 5-25% of a component B represented by structural formula (II), 5-25% of a component C represented by structural formula (III), and the balance of an assistant. The dye composition only contains two components, so the preparation steps are greatly simplified; the composition contains no chlorine-containing components, so the environmental protection performance of the composition is greatly improved, preparation of the chlorine-containing components is avoided, and the production cost and the environmental protection cost are greatly reduced; and the use amounts of the component A and the component B are reduced, and a strong deep color effect exists, so the production cost of the dye composition is further reduced on the premise of guaranteeing the brilliant color, the washing fastness, the scrubbing fastness, the perspiration fastness, the light fastness and the dyeing degree of a dyed sample cloth dyed by using the dye composition.

Description

technical field [0001] The invention relates to a disperse dye, in particular to a disperse yellow-brown 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. For example, the Chinese patent app...

Problems solved by technology

[0007] However, the composition of the dye composition is relatively complicated, the preparation process is cumbersome, and the preparation cost is high; and the component B contains chlorine atoms, and polychlorophenols need to be used in the preparation process of component B, and polychlorophenols with high toxicity Chlorophenols are a great threat to human health and environmental safety
