摘要
基于壳聚糖季铵盐良好的抑菌性和水溶性,将2,3-环氧丙基三甲基氯化铵与壳聚糖合成了壳聚糖季铵盐。采用最小抑菌浓度法测定和比较了壳聚糖及壳聚糖季铵盐的抗菌性,并将其用于桑蚕丝织物的抗菌整理,采用振荡烧瓶法对处理前后的丝织物进行抗菌性测试。结果表明:壳聚糖及其季铵盐对金黄色葡萄球菌和大肠杆菌均有显著的抑菌性,且壳聚糖季铵盐的抑菌效果优于壳聚糖;经壳聚糖及其季铵盐处理后,桑蚕丝织物对金黄色葡萄球菌和大肠杆菌的抑菌率均明显提高,且壳聚糖季铵盐的抑菌效果更好。
Quaternary ammonium salt of chitosan（HTCC） was prepared with 2,3-epoxypropyltrimethyl ammonium chloride and chitosan due to the good biocidal property and water-solubility.The antibacterial activities of chitosan and HTCC were tested and compared by minimal inhibitory method,and they were respectively applied to the antibacterial finishing of Bombyx mori silk fabrics.The antibacterial activities of silk fabrics before and after treatment were tested by oscillation flask method.The results showed that the biocidal properties of chitosan and HTCC to staphylococcus and coli were both significant,and HTCC was better than chitosan.The biocidal properties of silk fabrics to staphylococcus and coli were both significantly improved after treatment with chitosan and HTCC,and the biocidal property of silk fabric with HTCC treatment was better than that of chitosan.
