High-strength liquid disperse dye with low energy-saving emission and its production method and application

摘要

The present invention relates to a high-strength liquid disperse dye with reduced energy consumption, a method for producing the same, and an application thereof. The liquid disperse dye comprises, based on the total weight of the liquid disperse dye, the following components: one or more disperse dye base dyes having a total weight percent of 36% to 50%, 4.1% by weight. １１11% of an auxiliary, water having a weight percentage of 45% to 55%; the weight ratio of the auxiliary to the disperse dye base dye is 0.1 元 0.25: 1. This kind of energy-saving discharge-reduced high-strength liquid disperse dye is low in price, reduces energy-saving discharge, has high dye strength, high fluidity, is difficult to precipitate, has low chromaticity of residual dyeing solution, and has low COD. The robustness of each item is excellent.
