Abstract

The invention discloses disperse dye. The disperse dye comprises a component A represented by a structural formula (I), a component B represented by a structural formula (II), a component C represented by a structural formula (III), a component D represented by a structural formula (IV) and additives. On the basis of the mass fraction, the mass fraction of the component A is 2 to 15 percent, the mass fraction of the component B is 10 to 35 percent, the mass fraction of the component C is 5 to 10 percent, the mass fraction of the component D is 8 to 25 percent, and the balance is the additives. A cloth sample stained through the disperse dye has bright-colored light, excellent fastness to washing, fastness to rubbing, fastness to perspiration, color fastness to light and degree of dyeing.

Description

technical field [0001] The invention relates to the technical field of dyes, in particular to a disperse dye. 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] With the development of synthetic fibers, nylon and polyester have appeared one after another, especially polyester, because of its high alignment, less fiber voids, and strong hydrophobicity, it is necessary to expand the fiber with a carrier or under high temperature ...
