| 摘 要： | 为了解莲纤维的热学性能，采用热重和差热分析方法测试了莲纤维的热学特征，同时还测试了莲纤维热收缩率和极限氧指数。结果表明：随着温度升高，莲纤维的TG曲线有2个失重阶，在160℃左右开始热分解，主失重温度约为260℃；莲纤维的DSC曲线呈现出双熔融峰，较高熔融峰为324.7℃，较低熔融峰为377.7℃；莲纤维的沸水收缩率和干热空气收缩率分别为0.36%和0.3%，莲纤维的燃烧特征与棉、麻纤维类似，极限氧指数为17%-19%。

| Abstract: | TG and DSC was used to analyze the thermal property of lotus fiber. The heat shrinkage and limit oxygen index of the lotus fiber were also tested. The investigation showed that as the temperature increases, the lotus fiber's TG curves appear two weightloss bands. It begins to decompose at about 160 ℃, and the main weightloss temperature is about 260 ℃. The lotus fiber's DSC curve appears double melting peaks. The higher melting peak appears at 324. 7℃, and the lower one appears at 377.7℃. The heat shrinkages of lotus fibers in boiling water and hot air are 0. 36% and 0. 3% respectively. The combustion characteristics of the lotus fiber are similar with that of cotton and flax fiber, and the limit oxygen index of the lotus fiber is 17% - 19%. |
