[0002] In the printing and dyeing of polyester materials, most of the purple disperse dyes used in the market are darker 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 stains when printing, and the fineness of the printing pattern is not high

[0029] According to the data shown in Table 1, the original dye monomer A, dye monomer B, dye monomer C, and dye monomer D of the metering ratio are pre-dispersed and crushed, then add additives and warm water to stir, disperse and dissolve, and then grind continuously Repeat with filtration. After sanding to the end, it is sent to a spray drying tower through a pipeline for drying, and at the same time, it is evenly sprayed with dust-proof oil, and finally the finished product is packaged.

The invention belongs to the field of fine chemical engineering, specifically to a purple disperse dye composition for printing. The purple disperse dye composition is characterized by being preparedfrom the following components in percentage by weight: 1 to 20% of a dye monomer A, 3 to 15% of a dye monomer B, 5 to 30% of a dye monomer C and 0.01 to 15% of a dye monomer D as shown in a chemical formula (4). The purple disperse dye composition for printing provided by the invention does not contain forbidden aromatic amine components, is a green dye meeting environmental and ecological requirements prescribed in Oeko-Tex Standard 100, meets requirements prescribed in European Union Reach laws and regulations, is bright in color and luster, has excellent properties such as higher sublimation fastness, washing fastness and rubbing fastness and good compatibility, and particularly has more outstanding advantages in the aspect of lifting power. The fixation rate of the purple disperse dyecomposition is high; flooding generated in the printing process is greatly reduced; and the purple disperse dye composition is a high-performance dye meeting market development requirements.
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...
