Soaping enzyme, soaping method thereof and application of soaping enzyme in washed and dyed fabric

Abstract

The invention provides a soaping enzyme, a soaping method thereof and application of the soaping enzyme in washed and dyed fabric. The soaping enzyme comprises the following components in mass percentage: 40-65% of laccase, 5-20% of oxidase, 10-30% of fatty alcohol-polyoxyethylene ether, and 10-30% of isomeric alcohol polyoxyethylene ether. The soaping enzyme has decomposition and decoloration effects on hydrolyzed coloring matters in the solution and coloring matters adhered to fibers, and has no any influence to coloring matters combined with fibers via covalent bonds; meanwhile, washing and soaping procedures after dyeing can be shortened, water, energy and time are saved, production cost is lowered, and dyed fabric is enabled to acquire better washing fastness, perspiration fastness and rubbing fastness; moreover, the soaping enzyme is a biological agent, simple in use technology, easy to operation, more environmentally friendly, and safer in use.

Description

technical field [0001] The invention relates to the technical field of textile dyeing, in particular to a soaping enzyme, its soaping method and its application in cleaning dyed cloth. Background technique [0002] Due to the mature dyeing process and complete color spectrum of reactive dyes, especially in recent years, a series of dual reactive dyes with high fixation rate have been developed, so their applications are becoming more and more extensive. However, since the reactive dyes will be hydrolyzed while being dyed and fixed, the adsorption of the hydrolyzed dyes on the fibers will seriously affect the color fastness of the dyed products, so the reactive dyes must be soaped after dyeing. The main purpose of soaping is to remove hydrolyzed dyes, unfixed dyes and other impurities adhering to the fibers.

AI Technical Summary

Problems solved by technology

[0003] Traditional soaping agents such as acrylates, mainly through the complexation with hydrolyzed dyes, remove the floating color on the surface of the fabric, prevent the dyes in the lotion from re-sticking to the fabric, and improve the washing fastness of the fabric, but for dark colors Wet rubbing fastness of dyed fabrics is not obvious

In order to improve the color fastness of fabrics dyed with deep colors of reactive dyes, two times of high-temperature soaping and then strong washing with hot water are commonly used, or vat dyes with better fastness are used for dyeing. However, this method has a long production process and increases the consumption of water, electricity and steam. The absorbance of wastewater is deep, the discharge volume is large, the load of sewage treatment is large, and the production cost is high
