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%.
