Problems solved by technology

The current problem is that either the single auxiliary agent used in the pretreatment has low processing performance due to structural reasons, or the performance of the compound auxiliary agent is poor due to improper selection of the type of auxiliary agent used in the compounding or improper ratio between the components. Some improvement but not significant

Abstract

The invention belongs to the field of textile printing and dyeing industry, and discloses a compound auxiliary agent for one-step high-efficiency pretreatment of pure cotton fabrics and a preparation method thereof. The compound auxiliary agent is composed of polyoxyethylene ether nonionic surfactant, sulfonate anionic Two or three kinds of surfactants and sulfate anionic surfactants are blended and processed. The compound additive also contains phosphate or organic carboxylic acid sodium salt water softener. The above components are mixed and Stir at a temperature of 20-45°C for 15-60 minutes to make it evenly mixed. The invention is used as a compound auxiliary agent for one-step high-efficiency pretreatment of pure cotton fabrics, which has alkali resistance, oxidation-reduction agent resistance, hard water resistance and excellent penetration, emulsification, cleaning and other properties, and is especially suitable for the one-step process of pulp-containing pure cotton fabrics. Simplified treatment processes such as desizing, refining and bleaching have high practical significance for realizing high-efficiency and low-wastewater processing of pure cotton and cotton-type fabrics.

Description

technical field [0001] The invention relates to a composite auxiliary agent for one-step high-efficiency pretreatment of pure cotton fabrics, belonging to the field of textile printing and dyeing industry. Background technique [0002] The pretreatment process of pure cotton textiles is one of the key processes in the textile printing and dyeing process. The oil and other impurities attached to it make the fiber fully show its excellent quality, make the fabric white, soft, and have good permeability, so as to meet the wearing requirements, and provide qualified semi-finished products for the back-end processes of fabric dyeing, printing, and finishing. [0003] In the pretreatment process of cotton fabric, under the action of alkali, oxidant and other substances such as pulp, cotton fiber symbiosis or impurities, natural pulp, synthetic pulp and other material molecules are caused to swell or degrade, resulting in the separation between them and fibers. The adhesion is red...
