Problems solved by technology

[0003] As far as yellow and orange disperse dyes are concerned, the performance of general monochrome dyes is relatively single. In order to obtain yellow disperse dyes with more complete and better color fastness, it is necessary to use a variety of monochrome dyes with good compatibility and their own strengths. compound

Abstract

The invention discloses a medium-low temperature environmental-friendly disperse dye composition, which comprises the following components in percentage by weight: 3-94 percent of dye compound A as shown in the formula (1), 3-55 percent of dye compound B as shown in the formula (2), 3-60 percent of dye compound C as shown in the formula (3) and 0-2 percent of dye compound D as shown in the formula (4). The dye composition has the advantages of bright color shade, good synchronism during dyeing, good reproducibility, and good leveling-dyeing property, coverage property and each fastness, and particularly has more remarkable advantages on compatibility among dyes and sublimation fastness; and moreover, the invention is environmental-friendly and overcomes the defect that environmental protection and good fastness property cannot be achieved at the same time in the prior art.

Description

technical field [0001] The invention relates to a medium-low temperature disperse dye composition, which is especially suitable for dyeing and printing polyester materials and acetate fiber materials. Background technique [0002] With the rapid development of polyester fiber in recent years and the continuous improvement of people's requirements for textiles, correspondingly higher requirements have been put forward for the dyeing performance, fastness performance and environmental protection performance of the dye itself. [0003] As far as yellow and orange disperse dyes are concerned, the performance of general monochrome dyes is relatively single. In order to obtain yellow disperse dyes with more complete and better color fastness, it is necessary to use a variety of monochrome dyes with good compatibility and their own strengths. compound. Although the performance of compound dyes is better than that of single dyes, the compatibility between the single color dyes dete...
