Problems solved by technology

[0003] The substitutes currently on the market have better application effects. The most typical ones are SE-3R yellow from Wenzhou Kaiyuan Leather Co., Ltd. and E-RGFL yellow from Longsheng, but the compatibility of SE-3R yellow with 2BLN blue and 3B red is poor. , obviously asynchronous when dyeing; and the sublimation fastness of E-RGFL yellow is not ideal, especially when dyeing higher-grade polyester blended fabrics

Abstract

The invention discloses a low temperature environmental protection disperse yellow dye composition with good sublimation fastness and high lifting force, wherein the composition includes 15-35 percent dye monomer (1) as showed in formula(I), 2-19 percent dye monomer (2) as showed in formula (II), 0-5.9 percent dye monomer (3) as showed in formula(III), 0-10 percent dye monomer (4) as showed in formula (IV), and the rest are additives. The color light of the low temperature environmental protection disperse yellow dye composition of the invention is substantially close to C.I.23# yellow, and the performance of that is better than C.I.23# yellow. During dyeing, the invention has beautiful color light, high colorizing, good lifting force and high synchronism, and the sublimation fastness and exhaust dyeing rate are both better than C.I.23# yellow. The invention also has optimum compatibility with 2BLN blue and 3B red.

Description

technical field [0001] The invention relates to a dye composition, in particular to a low-temperature and environment-friendly disperse yellow dye composition, which is suitable for dyeing and printing of polyester and its blended fabrics, acetate fiber and nylon. Background technique [0002] With the promotion of the trend of the times, some colorful reds, oranges, yellows, etc. are widely used in the coloring of polyester and its blended fabrics, acetate fiber, and nylon. Among the yellow dyes, C.I. Disperse Yellow 23# (RGFL) is widely used in monochrome or color matching with 2BLN blue (C.I. Disperse Blue 56#) and 3B red (C.I. Disperse Red 60#). Under certain conditions, it will crack to produce carcinogens or aromatic amines that are harmful to the human body. It has been listed as a banned dye by Germany and other EU countries. Therefore, there is an urgent need in the market for a substitute that is similar to C.I. Disperse Yellow 23# in color light and performance, ...
