Problems solved by technology

However, due to the easy hydrolysis of reactive dyes, in the traditional process, there are problems of low dyeing rate and fixation rate
In order to ensure the color fastness, it is necessary to remove the hydrolyzed and unfixed dyes. Therefore, a post-treatment process that takes a long time, consumes a lot of energy, and consumes a lot of water is often required. In addition, the post-treatment process also brings serious pollution to the color of wastewater. And it is easy to cause disadvantag

Abstract

The invention discloses a clean type post-processing additive for a reactive dyeing cotton fabric. A method for preparing the clean type post-processing additive includes that firstly waste chicken feathers are used for preparing protein powders, then a sodium hydroxide solution is prepared, the chicken feather protein powders are dissolved with the sodium hydroxide solution, then a modifier WLS is prepared, and the chicken feather protein powders dissolved with the sodium hydroxide solution and the WLS are placed in a three-neck flask in a certain proportion and stirred at a certain temperature for some time to obtain the clean type reactive dyeing cotton fabric post-processing additive. The prepared post-processing additive has the advantages that preparing raw materials are sufficient, the price is low, biodegradation can be achieved, and the preparation is simple and convenient. According to a test, the dyed cotton fabric which is processed by the post-processing additive has the advantages that an effective color fixation can be achieved, the floating color content on the fabric is reduced, staining on white cloth is remarkably reduced during soaping, further the water consumption and the chroma pollution during floating color removing are reduced, water and energy are saved, and color fixation effect is good.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and relates to a post-processing auxiliary for fabric dyeing, in particular to a preparation method of a cleaning post-processing auxiliary for reactive dye dyed cotton fabric. Background technique [0002] At present, reactive dyes are an important class of dyes for dyeing cellulose fibers, and their applications are very extensive. However, due to the easy hydrolysis of reactive dyes, in the traditional process, there are problems of low dyeing rate and fixation rate. In order to ensure the color fastness, it is necessary to remove the hydrolyzed and unfixed dyes. Therefore, a post-treatment process that takes a long time, consumes a lot of energy, and consumes a lot of water is often required. In addition, the post-treatment process also brings serious pollution to the color of wastewater. And it is easy to cause disadvantages such as staining on the white background of ca...
