摘要：
The etherification agent 3-chloro-2-hydroxypropyltriethylammonium chloride was synthesized from triethylamine and epichlorohydrin. The quaternary ammonium type modified chitin (CCT) was synthesized by etherification reaction using chitin as raw material, and then deacetylated to obtain quaternary ammonium type cationic modified chitosan (CCTS). The chemical structure was characterized by FTIR and 13C NMR, and the physicochemical properties such as viscosity average molecular weight and solubility were measured by viscosity method and spectrophotometry. The antimicrobial activity of CCTS was determined by the minimal bacteriostatic method, and the minimum effective bacteriostatic concentration (MIC) of CCTS against Escherichia coli was 0.2g/L, which was better than the MIC value of natural chitosan. Using citric acid as crosslinking agent and sodium hypophosphite as catalyst, rabbit wool fabric was treated with CCTS to investigate its antibacterial effect and washing resistance. After 5 washes, the results showed that the antibacterial rate of CCTS against E. coli was above 99.9%, which was higher than that of CCT and natural chitosan. CCTS is a kind of natural macromolecule long - acting antibacterial finishing agent for animal wool fabric. © 2020, Chemical Industry Press. All right reserved.
