Abstract

The invention discloses a disperse dye composition with high washing fastness. The disperse dye composition is composed of component A represented by structural formula (I), component B represented by structural formula (II), and structural formula (III). Component C shown, component D shown in structural formula (IV), component E shown in structural formula (V), component F shown in structural formula (VI), component G shown in structural formula (VII), Component H shown in the structural formula (Ⅷ) and auxiliary agents are composed; by mass fraction, the mass fraction of the component A is 2 to 10%, and the mass fraction of the component B is 3 to 10%. The mass fraction of component C is 5-10%, the mass fraction of said component D is 8-25%, the mass fraction of said component E is 4-15%, and the mass fraction of said component F is 2 ~10%, the mass fraction of the component G is 3-18%, the mass fraction of the component H is 3-9%, and the rest are auxiliary agents. The invention has excellent washing fastness, rubbing fastness, perspiration fastness, light fastness and coloring rate.

Description

technical field [0001] The invention relates to the technical field of dyes, in particular to a disperse dye composition with high washing fastness. 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 wi...
