Emission-reduction plasma dyeing and finishing process

Abstract

The invention discloses an emission-reduction plasma dyeing and finishing process which comprises the following steps: 1, putting polyester cotton cloth into a plasma treatment machine for plasma treatment; 2, padding the polyester cotton cloth in a disperse dye, and executing dyeing under the negative-pressure circulation condition; 3, cleaning the dyed cloth; 4, padding the cleaned cloth in a reducing cleaning solution, adding composite hydrogel into the reducing cleaning solution, and executing standing after the secondary padding process is still under the negative-pressure circulation condition, wherein the composite hydrogel is acrylamide / nano silicon dioxide hydrogel; 5, wrapping the cloth subjected to secondary padding with plastic film, and executing steaming with 100 DEG C watersteam for 2 minutes; 6, executing washing with water and ventilation, and then executing soap boiling and air-drying. Therefore, the dyeing of the dye can be more sufficient. Moreover, the composite hydrogel can coat the surface of the cloth in a standing process. Therefore, by adopting the emission-reduction plasma dyeing and finishing process, the cloth is difficult to fade after being infectedby acidic pollutants.

Description

technical field [0001] The invention relates to a dyeing and finishing process, in particular to a discharge-reducing plasma dyeing and finishing process. Background technique [0002] Polyester cotton refers to the general term for blended fabrics of polyester and cotton, which are woven with 65%-67% polyester and 33%-35% cotton blended yarns. [0003] Visually, the color of polyester-cotton is brighter than that of pure cotton; if it is calico, the color concentration contrast between the front and back of pure cotton will be greater, while the color of the front and back of polyester-cotton is closer. [0004] In terms of hand feeling, pure cotton cloth is soft but not smooth, and polyester cotton cloth feels a little slippery to the touch. [0005] Pure cotton is better for the skin, pure cotton, 100% cotton fabric, feels soft and comfortable. Polyester cotton is a mixture of polyester and cotton, which is not as comfortable as cotton. It is not as sweat-absorbent as ...

AI Technical Summary

Problems solved by technology

[0006] In the existing technology, most of them use the traditional process for dyeing and finishing, but the traditional method has a large amount of emissions. Therefore, in the continuous development, practical plasma is used to treat polyester cotton, and then dyeing and finishing, which will greatly reduce emissions. However, in the actual process, it is found that the polyester-cotton fabric treated with plasma only treats the surface of the fabric, so during the dyeing process, the dye cannot fully dye the fabric, so the actual product is exposed to some acid pollutants. Discoloration will occur after cleaning, such as after soy sauce, vinegar, chili oil, etc.
