A kind of purple disperse dye composition for printing

Abstract

The invention belongs to the field of fine chemicals, and in particular relates to a purple disperse dye composition for printing, which is characterized in that the dye composition consists of the following components: a dye monomer A with a weight fraction of 1-20%, and a weight fraction of 3-20%. 15% of dye monomer B, 5-30% by weight of dye monomer C, and 0.01-15% by weight of dye monomer D of chemical formula (4). The purple disperse dye composition for printing provided by the present invention does not contain banned aromatic amine components, and becomes an environmentally friendly and ecological green dye conforming to Oeko-Tex Standard 100, meeting the requirements of EU Reach regulations, bright in 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. The high color fixing rate greatly reduces the floating color produced in the printing process. It is a high-performance dye that meets the requirements of market development.

Description

technical field [0001] The invention belongs to the field of fine chemicals, in particular to a purple disperse dye composition for printing. Background technique [0002] In the printing and dyeing of polyester materials, most of the purple disperse dyes used in the market are dull and not bright enough, such as C.I. Disperse Violet 93, C.I. Disperse Violet 33, C.I. Disperse Violet 77; Bright color can be obtained when polyester fiber is dyed, but its sublimation fastness is average, it is easy to produce white ground stains during printing, and the fineness of the printing pattern is not high. [0003] The present invention combines C.I. disperse violet 26 with other three azo and heterocyclic dyes to reduce the amount of C.I. disperse violet 26, improve printing performance, and achieve the same vividness as disperse violet 26. The mixed dye of the present invention complies with the environmental protection and ecological requirements of Oeko-Tex Standard 100 of the Eur...
