青蒿改性粘胶纤维结构与性能研究

Study on Structure and Property of Artemisia Annua Modified Viscose Fiber

探讨青蒿改性粘胶纤维的结构与性能。研究了青蒿改性粘胶纤维的结构、物理性能、染色性能和抗菌性能,并与普通粘胶纤维进行对比。结果表明:青蒿改性粘胶纤维形貌和组成与普通粘胶纤维相似,结晶度、机械性能、回潮率、上染率和固色率略低于普通粘胶纤维,但K/S值高于普通粘胶纤维;青蒿改性粘胶纤维对大肠杆菌和金黄色葡萄球菌的抑菌率高达99%以上,对白色念珠菌的抑菌率达到91%。认为:青蒿改性粘胶纤维具有良好的抗菌性。

Structure and property of artemisia annua modified viscose fiber were discussed.Structure,physical property,dyeing property and antibacterial property of artemisia annua modified viscose fiber were studied and compared with ordinary viscose fiber. The results showed that morphology and composition of artemisia annua modified viscose fiber were similar to that of ordinary viscose fiber,and its crystallinity,mechanical property,moisture regain,dyeing rate and fixation rate were slightly lower than that of ordinary viscose fiber,but the K/S value was higher than that of ordinary viscose fiber.Bacteriostatic rate of artemisia annua modified viscose fiber to escherichia coli and staphylococcus aureus were above 99% and bacteriostatic rate to candida albicans was reached91%.It is considered that artemisia annua modified viscose fiber has better antibacterial property.
