壳聚糖双胍盐酸的合及其在羊毛织物上多功能性的应用研究

利用壳聚糖和双氰胺成功地合成了一种壳聚糖双胍盐酸盐(CGH),对合成反应条件进行了讨论,并应用红外光谱确认了CGH的结构.将合成的CGH对羊毛织物进行处理,借助扫描电子显微镜SEM分析羊毛纤维整理前后的表面形态和结构,结果表明,羊毛织物经水溶性的CGH预处理后,可提高织物的吸湿性和抗皱性,再利用兰纳素活性染料进行轧染微波固色,可大大提高活性染料对羊毛织物的上染百分率.

Synthesis of chitosan biguanidine hydrochloride and application on wool fabric with multifunctional properties

Chitosan biguanidine hydrochloride (CGH) had been synthesized by the guanidinylation reaction of chitosan with dicyandiamide. Its synthetic condition was discussed. The structures of CGH were characterized by FT -IR. Water soluble CGH was prepared with a view to develop a multifunctional finish on wool. Results showed that treated wool had improved hygroscopicity and wrinkle resistance,the wool fabric treated CGH could obtain higher K/S value during dyeing with lanasol reactive dyes.
