A kind of red disperse dye composition for printing

Abstract

The invention belongs to the field of fine chemicals, and in particular relates to a red disperse dye composition for printing, comprising dye monomer A with a weight fraction of 0-20%, dye monomer B with a weight fraction of 0.01-10%, and a weight fraction of 0.01 -20% of dye monomer C, 0.01-15% of dye monomer D by weight, and the balance is composed of auxiliary agents. The red disperse dye composition for printing provided by the present invention does not contain prohibited aromatic amine components, and becomes a green dye that complies with Oeko-Tex Standard 100 environmental protection and ecology, meets the requirements of EU Reach regulations, has bright color, and has higher sublimation fastness, Excellent properties such as washing fastness, rubbing fastness and good compatibility, especially the advantages in lifting force are more prominent, and the color fixing rate is high, which greatly reduces the floating color produced in the printing process. It is a kind of product that meets the requirements of market development. High performance dyes.

Description

technical field [0001] The invention belongs to the field of fine chemicals, in particular to a red disperse dye composition for printing. Background technique [0002] In the printing and dyeing of polyester materials, the brilliance, pH sensitivity, sublimation fastness, washing fastness, rubbing fastness, and improvement rate of hot-melt dyeing of most of the red disperse dyes used cannot be considered mutually. Although the C.I. Disperse Red 92 can obtain bright color and good light fastness when dyeing polyester fibers, its printing coloring rate is very low, the dyeing cost is high, and the amount of pollution in the production process is large. [0003] The present invention combines C.I. disperse red 92 with other three azo and heterocyclic dyes to reduce the amount of C.I. disperse red 92, improve dyeing performance, and achieve the effect of compounding and solubilization. The mixed dye of the present invention complies with the environmental protection and ecolog...
