Abstract

The invention discloses a waterless-dyeing dispersed liquid dye and a preparation method and application thereof. The waterless-dyeing dispersed liquid dye is prepared from, by mass, 1-60% of a dispersed dye, 0.05-60% of a polymeric dispersant and water, wherein the polymeric dispersant is selected from at least one of an isooctanol polyethenoxy ether dispersant, an acrylic copolymer dispersant, apolyoxyethylene-polypropylene oxide copolymer dispersant, a styrene maleic acid resin polyether dispersant, a propylene glycol block polyether dispersant and a butynediol dispersant. The method includes: weighing raw materials, quickly beating for dispersion, sanding in a sanding machine, filtering to obtain the liquid dispersed dye, adding a mixture of the preservatives, an antifoaming agent andwater, subjecting the liquid dispersed dye to standardization, re-filtering and packaging. The liquid dye is applied to fabric dyeing and is effective in dyeing and free of water washing and wastewater especially in application to a thermosol dyeing or waterless dyeing process of a setting machine.

Description

technical field [0001] The invention relates to an anhydrous dyeing disperse liquid dye and a preparation method thereof. The anhydrous dyeing disperse liquid dye is mainly used in the anhydrous dyeing of fabrics, especially in the water-free dyeing method of hot-melt dyeing and the anhydrous dyeing method of a setting machine. Background technique [0002] In recent years, with the increasingly serious environmental problems, the country has higher and higher requirements for environmental protection, and a large amount of wastewater is produced in the printing and dyeing process. Realizing the ecological recycling of printing and dyeing water resources, energy saving and emission reduction is crucial to the healthy and sustainable development of my country's textile printing and dyeing industry and even the entire textile industry in the future. However, if the textile printing and dyeing wastewater is not properly treated, it will become a bottleneck problem hindering the...
