Problems solved by technology

Due to the high processing cost and complicated links, it is difficult to apply in actual production
[0005] 2. Post-dyeing processing: In order to reduce the water consumption of natural protein fiber dyeing and processing, some enterprises directly add alkali agent to the residual dyeing bath for alkaline washing, so that the residual dye that has not been fixed on the fiber enters the residual dyeing bath , after the residual bath is discharged, two washings are carried out, which reduces the water consumption in the post-dyeing process, but the total water consumption of the dyeing process is still as high as 30 to 40 times the quality of the dyed fiber, which cannot fundamentally solve the dyeing of natural protein fibers. Processing high water consumption and high pollution problems
In the above process of separating and isolating waste dyestuffs, various components in the natural protein fiber dyeing post-processing auxiliary XAM can affect the rubbing fastness of dyed products when dyeing medium-dark products, thereby affecting the quality of the final product Effect

Abstract

The invention discloses an auxiliary agent for separating a dye and a fiber in protein fiber in-situ mineralization dyeing and an application thereof, wherein the auxiliary agent for separating the dye and the fiber in protein fiber in-situ mineralization dyeing is prepared from polyacrylamide, fatty amine polyoxyethylene ether, sodium hydroxide, sodium carbonate and purified water. The invention further discloses a preparation method of the auxiliary agent for separating the dye and the fiber in protein fiber in-situ mineralization dyeing and a method for separating the dye and the fiber in protein fiber in-situ mineralization dyeing by using the auxiliary agent for separating the dye and the fiber in protein fiber in-situ mineralization dyeing. According to the auxiliary agent for separating the dye and the fiber in protein fiber in-situ mineralization dyeing and the application thereof, dyeing processing can be free of subsequent soaping and water washing processing, dyeing residual liquid after in-situ mineralization treatment can be anew applied in subsequent dyeing processing, and used water of the whole dyeing processing and pollutant emissions are significantly reduced.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and specifically relates to an auxiliary agent for separating dyes and fibers in in-situ mineralization dyeing of protein fibers. A method for separating dyes from fibers in in situ mineralization dyeing of protein fibers. Background technique [0002] A certain amount of residual dyes and residual dyeing auxiliaries often exist in the dyeing residual bath of natural protein fibers after dyeing, and a certain amount of residual dyes also exist on the dyed fibers. In the traditional dyeing process of natural protein fibers, the above-mentioned dyeing residual bath must be discharged, which results in higher dyeing wastewater treatment costs and the hidden danger of environmental pollution. In addition, in order to ensure the color fastness of the dyed fiber, it is necessary to carry out soaping and water washing with the main purpose of removing floating color. Generally spe...
