Abstract

The invention discloses a performance-improved disperse yellow dye mixture, which is prepared by mixing a dye part and an auxiliary part. The mixture is characterized in that the dye part is prepared by mixing at least dyes with the following two structures: one dye has a chemical structural formula (I) and accounts for 5-95% of the total mass of the dye part; and the other dye has a general chemical structural formula (II) and accounts for 5-95% of the total mass of the dye part; and in the formula (II), X is hydrogen or bromine.

Description

technical field [0001] The invention relates to a disperse yellow dye mixture, in particular to a performance-improving disperse yellow dye mixture suitable for dyeing polyester fibers or fabrics. This disperse yellow dye mixture can be used as one of the basic three primary colors to form a group of three primary color dyes with disperse red dyes and disperse blue dyes with the same or similar properties for color matching, and can also be used directly as a single dye for dyeing. Background technique [0002] For more than ten years, the following three types of disperse yellow dyes are usually used as one of the basic three primary colors in the color-blocking application of medium and light-colored medium-low temperature dyes for polyester fibers or fabrics, and C.I. Disperse Red 60 and C.I. Disperse Blue 56 ( Domestic product name: Disperse Blue 2BLN) for color matching: [0003] 1. Low-temperature single-structure disperse bright yellow dyes, such as C.I. Disperse Yel...
