Abstract

The invention relates to a low-temperature environment-friendly disperse dye, which comprises the following components in percentage by weight: 5-20 percent of monomeric dye A, 5-40 percent of monomeric dye B, 5-40 percent of monomeric dye C and auxiliary agent. The preparation of the low-temperature environment-friendly disperse dye has excellent dyeing property, especially good compatibility with other dyes, smooth dyeing curve, low dyeing temperature and wide range of PH adaptive values when dyeing, is suitable for rapid dyeing, helps a painting and dyeing enterprise realize energy saving and emission reduction and is especially suitable for painting and dyeing polyester materials and acetate fiber materials.

Description

technical field [0001] The invention belongs to the technical field of dyes and relates to a mixed disperse dye. Background technique [0002] Since the European Union listed disperse yellow RGFL as a prohibited dye, the search for substitutes that can replace disperse yellow RGFL has been carried out in China. Because the original disperse yellow RGFL has good application performance and a wide range of application bases, the varieties developed by various manufacturers are based on The shade close to RGFL is the standard, while paying attention to low-temperature dye uptake and compatibility with other low-temperature dyes. [0003] At present, the C.I. Disperse Yellow 23 products that have appeared on the market and have been used for a long time include Disperse Yellow SE-RGFL and Disperse Yellow SE-4RL produced by Zhejiang Shanyu Dye Chemical Co., Ltd., but the main problem of the above products is low temperature coloring The rate is poor, and it cannot adapt to the r...
