high-strength dispersed liquid dye of the energy-saving and pollution-reducing type, its manufacturing process and its use process

摘要

the present invention relates to a high strength dispersed liquid dye of the energy saving and pollution reducing type, the manufacturing process and the process for using it, the dispersed liquid dye being used to dye fabrics, especially for dyeing and printing polyester and fabrics mixed with it. based on the total weight, the dispersed liquid dye includes the following components: the percentage by weight of one or more raw dyes is in the range from 39.9% to 50%, auxiliaries 5% to 10.5%, and water 45 % to 54%; the weight ratio of auxiliaries to the dispersed crude dye is 0.1 to 0.25: 1. The dispersed liquid dye has the following advantages, low cost, energy saving and emission reduction, high resistance and good fluidity, does not precipitate easily, weak coloring in the residual dye liquid, low dqo and excellent color fastness performance.
