摘要
用羟甲基化和醚化等方法制备了改性壳聚糖羟甲基壳聚糖和羟乙基乙基醚壳聚糖。在中性条件下它们溶解于水。实验显示 ,改性壳聚糖具有较好的抑菌作用和吸湿保湿性能。对织物进行的后整理实验发现 ,羟乙基乙基醚壳聚糖适用于对棉布的整理加工 ,羟甲基壳聚糖适用于对真丝绸的整理加工。经整理后的织物具有较好的抗菌性 ,且吸湿、透湿、染色性能较优。研究表明改性壳聚糖可作为优良的功能性天然“绿色”
Carboxymethyl chitosan and Hydroxyethyl ethyl ether chitosan were made with the carboxymethylation reaction and the etherification reaction, respectively. The experimental results show that these modified chitosans could be dissolved in water. They had better antibiotic activity, the abilities of moisture absorption and remained moisture. Being used as fabric finish, Hydroxyethyl ethyl ether chitosan is found to be suitable for cotton fabric and carboxymethyl chitosan suitable for silk fabric.
