摘　　要：为改善大麻织物的柔软性能,使用环氧型有机硅油对大麻织物进行整理.借助扫描电镜、红外光谱、热重、差示扫描量热和X射线衍射测试技术分析了大麻纤维的结构,并测试了大麻织物的拉伸、硬挺和白度性能.结果表明,有机硅中的环氧基团和纤维素羟基发生了酯化反应;整理后的大麻纤维耐高温性能有所增强,分解率下降;晶粒尺寸基本没有改变,结晶度增加,取向度减小.整理后的大麻织物拉伸性能下降明显,柔软性提高,白度变化不大.In order to improve the stiffness,hemp fabric was treated using epoxy silicone oil,and then was investigated by means of SEM,FT-IR,TG,DSC and XRD.The properties of tensile,stiffness and whiteness were also measured according to GB3923—83,GB/T18318—2001 and ISO105/J02—1987,respectively.The results show that the active groups of epoxy silicone oil react with the hydroxyl group of hemp cellulose.The thermal stability of treated hemp fiber is improved,and the temperature at the maximum endothermic peak increased.The degree of crystallization increases,but the degree of orientation decreases.The size of crystal grain does not change.The tensile property of treated hemp fabric degrades.Treated hemp fabric becomes more softness,and the whiteness changes little.
