摘要: 采用甲醛甲酸法合成N,N,N-三甲基壳聚糖(TMC),再用三氯均三嗪与TMC反应,合成带有可与纤维反应的水溶性O-一氯均三嗪-N,N,N-三甲基壳聚糖(MCT-TMC)。采用FTIR、XRD、热重和元素分析等对产物进行表征,并测试其抗菌性能。将产物对羊毛织物进行抗菌整理,研究整理时间和浓度等工艺条件对抗菌性能的影响。结果表明,TMC和MCT-TMC具有较好的抗菌性能;将其用于羊毛织物抗菌整理的最佳工艺条件为:整理时间60min,整理浓度分别为3%(owf)和2%(owf);经TMC整理的织物对E.coliS.aureus的抑菌率分别为97.8%和99.2%,MCT-TMC整理的织物对E.coliS.aureus的抑菌率分别为98.6%和99.8%。MCT-TMC整理羊毛织物的耐洗涤性能比TMC有显著提高,洗涤后抑菌率仍达到90%以上。

Abstract: N,N,N-trimethyl chitosan(TMC) were synthesized by the formaldehyde-formic acid method,which was then reacted with cyanuric chloride to prepare fiber reactive and water soluble O-monochlorotrazinyl-N,N,N-trimethyl chitosan(MCT-TMC). FTIR,XRD,TG and elemental analysis were used to characterize the products,and their antibacterial properties were also tested. Wool fabrics were treated by the products. The antibacterial properties of the fabrics were measured to investigate the impact of the treatment time and concentration. The results confirmed that the synthesized products have good antibacterial activity. The best treatment time for wool fabric of TMC and MCT-TMC is 60min,and the optimum concentration of TMC and MCT-TMC are 3%(owf) and 2%(owf),respectively. Inhibition rates of fabric treated by TMC against E. coli and S. aureus are 97.8% and 99.2%,while those by MCT-TMC are 98.6% and 99.8%,respectively. The washing resistance of wool fabric treated by MCT-TMC is significantly higher than that by TMC,which is still up to 90% after washing.
