Problems solved by technology

At present, the mainstream high-washing products in the market are concentrated on powder dyes, while liquid dyes are mainly concentrated on conventional dyes for wash-free printing and dip dyeing. These dyes have relatively poor washing fastness when used on ammonia-containing or ultra-fine fabrics. Sanding is relatively difficult for high-washing dyes, and there are basically no reports on liquid dyes that can be used in polyester-ammonia dyeing and obtain high washing fastness

Abstract

The invention discloses a nano liquid disperse dye with high washing fastness as well as a preparation method and application thereof, and belongs to the field of textile chemical industry. The nano liquid disperse dye with high washing fastness is prepared from the following components in percentage by mass: 10 to 60 percent of disperse dye, 4 to 16 percent of macromolecular anionic dispersant, 0.1 to 8 percent of traditional anionic dispersant, 0.1 to 5 percent of humectant, 0.05 to 1 percent of defoaming agent, 0.02 to 4 percent of thickening agent, 0.02 to 0.2 percent of preservative and the balance of water, wherein the polymeric dispersant is an anionic dispersant and comprises one or more of an alkylphenol polyoxyethylene ether anionic surfactant, a modified styrene polyoxyethylene ether anionic surfactant and a polycarboxylic acid hyperdispersant. The nano liquid disperse dye with high washing fastness provided by the invention avoids the problems of spray drying and chemical material dust pollution of conventional powdery commercialization, has high washing fastness, and is a novel functional dye processing mode.

Description

technical field [0001] The invention relates to a nanometer liquid disperse dye with high washing fastness and its preparation method and application, belonging to the field of textile chemical industry. Background technique [0002] The commercialization of disperse dyes is a process in which filter cakes, fillers, auxiliaries, etc. are dispersed by grinding, and then spray-dried. Excessive filling of auxiliaries in the commercial processing of dyes will hinder the dyeing on the one hand, and on the other hand, a large amount of auxiliaries will increase the COD of dyeing wastewater after dyeing is completed, causing environmental pollution. Unlike powder dyes, liquid dyes save the spray drying process and are an emerging dye processing technology. At the same time, liquid dyes can choose a wider range of dispersants and more diverse forms, and use less high-efficiency surfactants instead of traditional anionic dispersants (MF, CNF, etc.) to achieve good dispersion effects...
