摘　　要：为提高传统共混工艺制备的阻燃粘胶纤维的耐水洗性,通过在阻燃粘胶液中加入自制硅烷偶联剂,间接地将纤维素和阻燃剂结合起来,减少水洗过程中阻燃剂的流失,考察了偶联剂用量、成膜温度及成膜时间对水洗后阻燃粘胶膜的极限氧指数(LOI)的影响。极限氧指数测试和能谱分析表明,硅烷偶联剂的适量加入有效减缓了阻燃粘胶膜LOI的下降。In order to improve the washing durability of fire-resistant viscose fiber which was prepared by blending technology,self-made silane coupling agents were added into the fire-resistant viscose solution in the experiment,affer which the cellulose was connected with the flame retardants indirectly,and the flame retardants loss in the process of washing was decreased.The effects of coupling agents＇content,coagulation bath＇s temperature and residence time in coagulation bath on flame-resistant of viscose film after washing were investigated respectively.The results of LOI and EDS show that the falling rate of LOI for flame-retardant viscose fiber is slowed down effectively with suitable amount of silane coupling agents.
