Embodiment 1

[0020] Component A of 90 grams of formula (I), component B of 2 grams of formula (II), component D of 8 grams of formula (IV), 150 grams of dispersant MF, 30 grams of sodium lignosulfonate, add water 720 After blending, grind and disperse with a grinder, and spray dry to obtain the finished product. The dye can provide red color with excellent fastness properties to fabrics.

Abstract

The invention relates to one disperse red dye composition and dye products, disperse red dye composition is prepared from three or four of component A, component B, component C and compounded D of compounded products, dye product comprises dye and auxiliary two sorts and is mixed prepared. Dye composition is widely used in hydrophobic fiber materials such as polyester fiber and superfine polyester dyeing, especially suitable for the dyeing of polyester / polyurethane elastic fabric with high requirements on fabric color fastness.

Description

technical field [0001] The invention belongs to the field of dye compositions, in particular to a disperse red dye composition and dye products suitable for printing and dyeing textile fiber materials, especially hydrophobic fiber materials. Background technique [0002] From the perspective of environmental and ecological requirements, it is inevitable to develop new high-performance disperse dyes to replace allergic disperse dyes and toxic disperse dyes. Due to the slow development of new structures of disperse dyes, a lot of work has turned to the application performance of dyes, the research on the compounding and synergy between dyes and dyes and auxiliaries. But from the existing composite disperse red dye, its lifting power and dyeing depth are not high, such as published patents CN1827705, CN1861697 and the like. [0003] The present invention uses specific components to form a new disperse dye composition through research on compounding synergies of disperse dyes, ...
