Contamination-proof detergent washing agent for textile dyeing printing process

Abstract

The invention relates to an assistant agent used for dyeing and printing a textile, particularly a cleaning agent used for preventing a contaminant during the soaping process after the textile is dyed and printed, and belongs to the textile dyeing technology field. The assistant agent comprises the following components by mass percentage: 2% to 15% of N-vinyl pyrrolidone / acrylamide / vinyl alcohol terpolymer, 2% to 15% of maleic acid / acrylic copolymer, 0 to 10% of sodium polyacrylate, 2% to 15% of aliphatic amine polyethenoxy ether, 2% to 15% of fatty alcohol polyoxyethylene ether, and water in balancing amount. The assistant agent has the advantages that: the components meet the standard of ecological textiles and the environmental protection requirements, the assistant agent has a certain cationic nature, thus having good affinity for the anionic dye used for conventional dyeing and printing, is conducive to washing and removing the dye which is attached to the textile, and meanwhile, has protective colloidal properties, thus allowing the removed dye to be stably existing in a washing solution, so as to prevent second contamination.

Description

technical field [0001] The invention relates to an auxiliary agent for textile dyeing and printing, in particular to a cleaning agent used for anti-pollution in the soaping process after textile dyeing and printing, and belongs to the technical field of textile dyeing and finishing. Background technique [0002] In the textile printing and dyeing industry, fabric printing processing mainly includes the following processes: pattern making, color paste preparation, printing, drying, washing, post-treatment and other processes. The purpose of the washing process is to wash away unfixed dyes and dyes on the fabric. Use the finished size and other printing and dyeing auxiliaries to improve color fastness, restore hand feeling, and obtain printed fabrics with bright and clear patterns. The general requirement for the cleaning agent used is that it can effectively wash away unfixed dyes and sizing, and no longer stick to the surface of the fiber, without excessive stripping; no dam...

AI Technical Summary

Problems solved by technology

But so far, the high polymers used in compound soaping agents are mainly anionic, and the effect on dyes mainly depends on the adsorption and dispersion of high molecular compounds. The force is not strong enough, and the ability to remove floating color is insufficient, affecting Fastness and quality of dyed fabrics

In the Chinese invention patent "Textile White Ground Anti-staining Detergent" (CN 1302174C), the chemicals used, such as alkylphenol polyoxyethylene ether, alkylbenzene sulfonate, etc., along with the ecological textile regulations and environmental protection requirements Improvement, the use has been restricted, at the same time, the methylpyrrolidone and vinylpyrrolidone used are low-molecular compounds, which have low affinity for dyes and poor anti-staining effect
