Abstract

The invention relates to a polymeric decontamination color fixing agent for a fabric. The color fixing agent is copolymer formed by initiating 2-acrylamide-2-methylpropanesulfonic acid, acrylamide, dimethyl diallyl ammonium chloride, dimethyl diallylamine, high molecular weight polyvinyl pyrrolidone (PVP) and an emulsifier through an initiator, wherein preferably, the high molecular weight PVP is PVPK90-K95, the emulsifier is an ethylene oxide propylene oxide (EOPO) emulsifier, and the initiator is azobis(isobutylamidine hydrochloride); and preferably, the color fixing agent comprises 1g of 2-acrylamide-2-methylpropanesulfonic acid, 20g of dimethyl diallyl ammonium chloride, 5g of dimethyl diallylamine, 20g of acrylamide, 2g of high molecular weight PVP and 2g of emulsifier. The color fixing agent can enhance the hydrophilic breathability and decontamination capability of the fabric, improve the wet rubbing fastness of the fabric and effectively improve the content of formaldehyde in the fabric, is healthy and environmental-friendly, improves the quality and functions of the fabric, and has a wide market prospect.

Description

technical field [0001] The invention relates to the technology of hydrophilic, moisture-permeable and easy decontamination finishing of fabrics, and the improvement of wet rubbing fastness after dyeing, more specifically, the technical field of polymer decontamination and color-fixing agents for fabrics. Background technique [0002] After China's accession to the WTO, the quality requirements of textile products must be in line with international standards. The most important ones are the high requirements for the decontamination ability, color fastness, formaldehyde content, hydrophilic moisture permeability and other functions of functional fabrics. Foreign orders require that the formaldehyde content of underwear is less than 30mg / kg, and Wet rubbing fastness requires grade 2-3 or above. The European Union, the United States, Japan and other countries use these two indicators to limit the export of Chinese textiles and create technical barriers. In addition, the require...
