Abstract

The invention relates to a macromolecular wet friction fastness promoting agent, which is a copolymer formed by 2-acrylamide-2-methylpropane sulfonic acid, acrylamide, diallyldimethylammonium chloride, diallyldimethylammonium, high molecular PVP and an emulsifier initiated by an initiating agent, preferably, the high molecular PVP is PVPK90-K95, the emulsifier is an EOPO emulsifier, the initiating agent is azodiisobutylamidine hydrochloride, the range of the dosage of the raw materials is 0.1mol-3mol, the inventive macromolecular wet friction fastness promoting agent has excellent performance and can better promote the wet friction fastness of fabrics, meanwhile, the invention effectually lowers the content of formaldehyde in the fabrics, is quite environmentally-friendly, improves the quality of the fabrics and has extensive market prospect.

Description

technical field [0001] The invention relates to the technical field of fabric wet rubbing fastness improvement, more specifically, to the technical field of fabric wet rubbing fastness improving agent, in particular to a polymer wet rubbing fastness improving agent. 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 of these are the requirements for formaldehyde content and color fastness on fabrics. The European Union, the United States, Japan and other countries attempt to use these two indicators to limit the export of Chinese textiles, resulting in technical barriers. Foreign orders have very strict requirements on color fastness, wet rubbing fastness should be above grade 2-3, and underwear with formaldehyde content should be lower than 30mg / kg. At present, it is difficult for my country's printing and dyeing factories to complete such high-dema...
