Silk/wool fiber dyeing method and post-dyeing sewage treatment device thereof

Abstract

The invention discloses a silk / wool fiber dyeing method and a post-dyeing sewage treatment device thereof, and the method comprises the following steps: pre-drying silk / wool blend fibers, and then carrying out plasma pretreatment; dyeing the wool in an acid bath; dyeing silk in an alkaline bath; soaping under a weakly alkaline condition, and then washing with water; the treatment device comprises a treatment pond, a plurality of water flow channels are formed in the treatment pond, a plurality of water treatment assemblies perpendicular to the flowing direction of water flow are rotationally connected into the water flow channels, the water treatment assemblies are partially exposed out of the water surface, a filter plate is arranged below the water flow channels, and an air flotation device is arranged below the filter plate; a slag scraper is arranged between the filter plate and the water flow channel, a plurality of scraping plates are arranged on the slag scraper, V-shaped hooks are arranged at the bottoms of the scraping plates, and bristles are arranged at the ends of the V-shaped hooks. The method has the characteristics that the dyeing cochromaticity of the silk / wool mixed fiber is improved, the sewage discharge amount is reduced, and the pollution to the environment is reduced.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a silk / wool fiber dyeing method and a sewage treatment device after dyeing. Background technique [0002] Mixed fibers are made by blending or blending two or more different fibers, such as cotton and linen, cotton wool, cotton polyester, silk wool, etc. The characteristics of mixed fibers are the integration of the advantages of different fibers, such as wrinkle resistance, lightness, warmth, flame retardant, etc. , to overcome the inherent shortcomings of single fiber such as fluff and wrinkle, poor warmth retention, poor hygroscopicity, and flammability. Silk / wool mixed fiber is a fiber that is blended with silk and wool, which not only has the fluffy and warm properties of wool, but also has the strength and luster of silk. In the dyeing process of silk / wool mixed fibers, because of the existence of a hydrophobic dense scale layer on the surface of wool fibers, which hinders the ...

AI Technical Summary

Problems solved by technology

Due to the different dyeing conditions of silk and wool, the color obtained during dyeing is different, and it is difficult to dye the same color of silk / wool mixed fibers, and generally needs to use a variety of dyes and auxiliaries during dyeing, and the amount of sewage generated after dyeing is large, polluting A lot of things, difficult to deal with, great pollution to the environment
