壳聚糖胍盐酸盐的制备及其在羊毛织物抗菌整理中的应用

采用微波辐射技术,以壳聚糖胍亚硫酸盐和浓盐酸为原料,合成了一种壳聚糖胍盐酸盐抗菌剂,通过红外光谱和核磁谱图对其结构进行表征。将壳聚糖胍盐酸盐用于羊毛织物的抗菌整理,通过研究整理剂质量浓度、焙烘温度、焙烘时间对整理后羊毛织物抗菌效果和物理力学性能的影响优化整理工艺。结果表明,在微波辐射条件下成功合成了壳聚糖胍盐酸盐抗菌剂,整理剂在羊毛织物上的较佳整理工艺为壳聚糖胍盐质量浓度10 g/L,焙烘温度130℃,焙烘时间5 min。

Preparation of chitosan guanidine hydrochloride and application thereof in antimicrobial finishing of wool fabric

Antimicrobial chitosan guanidine hydrochloride was synthesized by reacting chitosan guanidine sulfite with concentrated hydrochloric under microwave irradiation. The structures of guanidinylated chitosan were characterized by FT-IR and 13CNMR. Chitosan guanidine hydrochloride was applied to the antimicrobial finishing of  wool fabric and the the infouences of finishing conditions including antimicrobial agent mass concentration, curing temperature and curing time on the antimicrobial effect and physical mechanical properties were researched. The results show that antimicrobial chitosan guanidine hydrochloride was synthesized successfully under microwave irradiation. The optimal procedure parameters for finishing agent on wool fabric are as followed: mass concentration of chitosan guanidine hydrochloride of 10g/L, curing temperature of 130℃ and curing time of 5min.
