摘　　要：通过改变碱浓度对棉秆皮纤维进行改性处理,对碱处理前后棉秆皮纤维的长度、细度、可挠度、断裂强力及断裂伸长等性能进行测试.实验得到,随着碱浓度的提高,纤维的强度、长度、细度减小,纤维的可挠度增加.The cotton bast fiber was treated by various alkali concentrations,and the length,fineness,flexibility,breaking strength and breaking elongation were tested.Experimental results show that the strength,length and fineness of the modified cotton bast fibers decreased,and flexibility of modified cotton bast fibers increased with the increase of alksli concentartion.
