Disperse deep blue dye color paste and preparation method thereof

Abstract

The invention discloses disperse deep blue dye color paste and a preparation method thereof. The disperse deep blue dye color paste is prepared from disperse deep blue dyes, a reverse salt, a water-soluble nonionic surface active agent, a nonionic thickening agent, an oil-soluble nonionic surface active agent, ethyl alcohol, starch, acetic acid vinyl ester, acrylic acid, emulgator, urea, a corrosion remover, a dispersing agent, glacial acetic acid and chitosan, and further is prepared from a penetrating agent, a levelling agent and a migration inhibitor. According to the disperse deep blue dyecolor paste and the preparation method thereof, the dispersing agent and the disperse deep blue dyes are mixed evenly, the water-soluble nonionic surface active agent and the oil-soluble nonionic surface active agent are added to be ground to 50-700 nm, the obtained color paste is good in stability, moderate in viscosity, capable of being dispersed in water for a long time and not prone to sediment, does not need water washing, achieves energy saving, environmental protection and emission reduction, has good dye transmissibility and permeability, and has high transfer rate and good washing fastness.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a disperse dark blue dye paste and a preparation method thereof. Background technique [0002] Disperse dyes have the characteristics of complete color spectrum, bright color, high fastness and not easy to decompose. They are widely used in dyeing and printing of polyester, nylon, acetate fiber and other synthetic fibers. At present, the water dyeing method commonly used in the domestic printing and dyeing industry for the printing and coloring of polyester and chemical fibers, and the traditional disperse dyes are granular, with a particle size of more than microns, and there are many disadvantages: 1. High temperature steaming is required to develop color, wasting a lot of steam Energy; 2. The utilization rate of the dye agent is low, the floating color is large, and the utilization rate of the dye is 65%-70%; 3. Due to the large particle size, although it can be dispersed in water for a sh...

At present, the water dyeing method commonly used in the domestic printing and dyeing industry for the printing and coloring of polyester and chemical fibers, and the traditional disperse dyes are granular, with a particle size of more than microns, and there are many disadvantages: 1. High temperature steaming is required to develop color, wasting a lot of steam Energy; 2. The utilization rate of the dye agent is low, the floating color is large, and the utilization rate of the dye is 65%-70%; 3. Due to the large particle size, although it can be dispersed in water for a short time, it will precipitate after a long time, and the traditional Disperse dyes need to be washed many times during the dispersion process, which wastes water resources and easily produces sewage, which needs to be treated and wastes resources.

[0003] And because the main ways of polyester printing are direct printing, paint printing, heat transfer printing, and direct printing is the main way of printing at present. It is a kind of printing paste with a certain viscosity prepared from commercially available dyes, pastes and additives. Then carry out the traditional processing technology of printing, drying, steaming and multi-channel water washing; with the development of synthetic thickeners with high viscosity and low solid content, the amount of synthetic thickeners in printing pastes can be reduced, but due to Existing disperse dyes have poor compatibility with synthetic thickeners. In order to obtain a printing paste with a certain viscosity, it is still necessary to configure a synthetic thickener printing paste with a high solid content (such as 5-6%) to prevent printing Decrease in the viscosity of the medium
