反应性壳聚糖季铵盐的合成及其改性棉织物的抗菌性能
Synthesis of reactive chitosan quaternary ammonium salt and antibacterial properties of modified cotton fabric
摘要
Abstract
In order to improve the water- solubility of chitosan and strengthen its binding force with the cotton fiber, 2- hydroxypropyltrimethyl ammonium chloride chitosan (HTCC) was synthesized using chitosan and 2,3- epoxypropyltrimethyl ammonium chloride, then HTCC was reacted with N- (hydroxymethyl)- acryl⁃amide, and the water- soluble O- methyl acrylamide quaternary ammonium salt of chitosan (NMA- HTCC) with fiber reactive groups was synthesized. FT- IR and 1H- NMR were used to characterize the synthesized NMA- HTCC, which was then applied on the antibacterial finish of cotton fabrics. The antibacterial properties of cotton fabrics before and after treatment were tested by oscil ation flask method to explore the optimum process conditions of cotton fabric treated with NMA- HTCC. The results showed that when the concentration of NMA- HTCC was 7 g/L, the mass fraction of NaHCO3 was 2%, treated at 60 ℃ for 50 min, cured at 160 ℃for 3 min, the inhibition rate of cotton fabrics to Staphylococcus aureus and Escherichia coli were the best and stil higher than 90%after 30 times of soaping.关键词
