摘　　要：莲纤维是一种新型天然纤维,其性能和应用还有待于探索,在工业化应用中突出莲纤维特性,研究其化学和热学性能将为其化学及染整加工提供依据。对2种不同方法制备的莲纤维物理机械性能、耐酸和碱、氧化性进行测试和分析,采用差示扫描量热法(DSC)进行热学性能测试,结果表明:莲纤维在强酸、强碱环境下溶解,在强氧化剂环境下发生部分溶解,扫描量热法测出抽丝莲纤维的失重率为42.7%,脱胶莲纤维的失重率为66.6%,抽丝莲纤维的热学性能优于脱胶莲纤维。Lotus fiber is a new type of natural fiber,its performance and application still need to be explored.Highlighting the characteristics of lotus fiber in industrial application and studying its chemical and thermal properties will provide a basis for its chemi-cal and dyeing and finishing processing.The physical and mechanical properties,acid and alkali resistance and oxidation resistance of lotus fiber prepared by two dfferent methods were tested and analyzed,and the thermal properties of lotus fiber were tested by differ-ential scanning calorimetry(DSC).The results showed that the lotus fiber was dissolved in strong acid and alkali environment,and partially dissolved in strong oxidant environment.By scanning calorimetry,the weight loss rate of lotus fiber was 42.7%and the weight loss rate of degummed lotus fiber was 66.6%.The thermal properties of the silk lotus fiber are better than that of the de-gummed lotus fiber.
