Actions of Temperature on the Structure and Properties of Hemp Fibre
Abstract:
As to demonstrate the effect of treatment temperature on hemp fibre, this article recorded and compared the change of supramolecular structure and properties of hemp fibre under different processing temperature (150°C and -30°C). The result shows: the change of processing temperature can affect the crystallinity of hemp fibre, with the rise of treatment time, the crystallinity of fiber increases at high temperature and is contrary at low temperature. Meantime, the degree of thermodynamic change is higher at low processing temperature than that of high temperature. Furthermore, with the rise of treatment time, the moisture regain of fibre fluctuates under high temperature and rises under low temperature.
