Soaping agent and soaping process for high-density patterned pure cotton figured cloth

Abstract

The invention belongs to the technical field of dyeing and finishing, and specifically relates to a soaping agent and a soaping process for high-density patterned pure cotton figured cloth. The soaping agent for high-density patterned pure cotton figured cloth is prepared from the following raw materials: N-vinyl pyrrolidone, sodium lauryl sulfate, delta-laminated sodium metasilicate, dodecyl dimethyl betaine, etidronic acid, maleic anhydride, polyacrylic acid, compound soaping enzyme, octadecyl amine ethoxylate ether, secondary alkyl sodium sulfonate and thiourea dioxide, wherein the compound soaping enzyme is composed of laccase, lipopenic enzyme, Eurolan RP soaping enzyme and EOQ soaping enzyme. The soaping agent has less foam and short foaming time when used in soaping high-density patterned pure cotton figured cloth; the soaped pure cotton figured cloth can not fade or change color; dyed fabric of the high-density patterned pure cotton figured cloth processed by the soaping agent combined with the soaping process basically has no color difference and strong loss; and compared with the traditional soaping process, the color fastness is higher, working procedures are reduced, and time and energy are saved.

Description

technical field [0001] The invention belongs to the technical field of dyeing and finishing, and in particular relates to a soaping agent for high-density patterned pure cotton cloth and a soaping process thereof. Background technique [0002] Reactive dyes, direct dyes, acid dyes, disperse dyes, etc. must be washed and soaped after dyeing, and soaping agents are needed. After pure cotton fabrics are dyed with reactive dyes, appropriate soaping agents need to be selected for soaping to improve product quality. quality and reduce energy consumption. [0003] In the dyeing and printing process of reactive dyes, reactive dyes endow dyed and printed fabrics with excellent color fastness through covalent bonding, but reactive dyes are prone to hydrolysis under alkaline conditions, forming hydrolyzed dyes that cannot react with fibers, and Part of the dye is adsorbed on the surface of the fiber without participating in the covalent reaction. It must be cleaned in the post-treatme...

Problems solved by technology

[0006] The purpose of the present invention is to provide a solution for the problem that the current soaping agent has a high pH value and a high temperature during the soaping process, resulting in bond breakage of reactive dyes and a lot of foam in the lotion, which consumes a large amount of water and is not conducive to environmental protection. Soaping agent and its soaping process for high-density flower-type pure cotton cloth, the soaping agent has less foam and short foaming time when soaping high-density flower-type pure cotton cloth; It will not fade and change color; and the dyed fabric of the high-density patterned cotton cloth after the soaping agent is combined with the soaping process mentioned above has basically no color difference and loss of strength. Compared with the traditional soaping process, the color fastness is higher , and reduce the process, save time and energy
