甲壳素纤维的力学性能研究

Study on the Mechanical Property of Chitin Fiber

测试了甲壳素纤维基本力学性能,并与普通粘胶纤维进行对比,对其可纺性和服用性进行了分析。结果表明:甲壳素纤维强度和伸长率比粘胶纤维小,湿态下纤维力学性能降低程度没有粘胶大;甲壳素纤维比粘胶纤维的弹性好,相同定伸长,甲壳素纤维松弛所需时间更长,蠕变变形同粘胶。

The mechanical properties of chitin fiber were tested.The spinnability and wearability were analyzed compared with common viscose fiber.The results showed that the strength and elongation of chitin fiber were lower than viscose fiber,and the mechanical properties decreasing in wet state were lower than viscose fiber,but elastic recovery rate of chitin fiber was higher than viscose fiber.At the constant elongation,the relaxing time of chitin fiber was much longer and the creep deformation was similar with viscose fiber.
