摘　　要：在芝麻纤维素碱消晶的溶胀状态下，于碱纤维素的经基上接技阳离子基团，以阻碍纤维素分子链的重新靠近形成氢键，而避免纤维素分子的重结晶，起到继续保持消晶的溶胀效果。文中选用十二烷基二甲基辛基氯化按（1227）作为阳离子化改性剂的主要成分，在赋予改性芝麻纤维的特种功能，如抗静电、抗菌、优良染色性能以及柔韧而有弹性等方面取得了较好的效果。The rande fiher was modified with grafting 0f cationic - gnup and decrystallization in the swelled state of soda celluIose. Cationic - group was grafed on the hydroxyl of soda - cellulose blocking the formati0n of hydrogen bonds between the molecular - chain to prevent cellul0se recrystallization. It is important t0 select special functi0nal cationic - group with low ratio -resistance, bacteria resistant, fungistatic, sofness and heatproof in the process of grafing and decrystallization. The modified ramie fiber have better static electricity resistance, dyeability, high break - function, and have bend - p0int stretch curve which made it pliable and tough e1asic.
