Problems solved by technology

At present, the blue disperse dyes with high wet fastness such as C.I. Disperse Blue 284 and Ciba high washing fastness disperse dyes (the disperse dyes described in patent CN1331730A and CN1234418A) also have deficiencies. When the ester group is prone to hydrolysis, the pH range of the dyeing bath is narrow and the dyeing reproducibility is poor
Second, the dyeing rate is low, and the color of the dyeing bath residue is deep
Third, some products are expensive, which also limits the scope of application

Abstract

The invention discloses a blue disperse dye mixture for printing and dyeing polyester materials, which is characterized by comprising the following components in percentage by weight: 5 to 20 percent of dye A, 3 to 28 percent of dye B, 12 to 30 percent of dye C, 0 to 25 percent of dye D, and 45 to 70 percent of dispersant. The blue disperse dye mixture has the characteristics of high dye uptake, good dyeing reproducibility, good leveling property, good fastness and the like, and particularly has excellent dye uptake and wet fastness, and wide dyeing pH range.

Description

Technical field: [0001] The invention relates to a blue dye mixture, in particular to a blue disperse dye mixture for printing and dyeing polyester materials. Background technique: [0002] In the printing and dyeing of polyester materials, disperse dyes with high dyeing uptake, excellent fastness and good dyeing reproducibility have always been the focus of development and research. In particular, disperse dyes with excellent dye uptake and wet fastness have become a hot spot for development. At present, the blue disperse dyes with high wet fastness such as C.I. Disperse Blue 284 and Ciba high washing fastness disperse dyes (the disperse dyes described in patent CN1331730A and CN1234418A) also have deficiencies. When the ester group is prone to hydrolysis, the pH range of the dyeing bath is narrow and the dyeing reproducibility is poor. Second, the dye uptake rate is low, and the color of the dye bath residue is deep. Third, some products are expensive, which also limits...
