摘　　要：以N-甲基吗啉-N-氧化物(NMMO)为溶剂溶解纤维素浆粕制备纺丝液,再通过气流溶喷纺工艺制备纤维素溶喷非织造材料。探讨纺丝过程中预凝固水雾距离与牵伸距离对纤维素溶喷非织造材料结构性能的影响。试验结果显示,适度增大预凝固水雾距离与牵伸距离,能够减小纤维素溶喷非织造材料的纤维直径,提高其结晶度,使非织造材料结构更蓬松,透气性能与吸液性能更好。Cellulose pulp was dissolved in N-methylmorpholine-N-oxide(NMMO)solvent to prepare the spinning solution,and then cellulose solution-blown nonwovens were prepared by air-jet solution-blown spinning process.The influence of pre-coagulation water mist distance and drafting distance on the structure and properties of cellulose solution-blown nonwovens during spinning process was investigated.The experimental results indicated that increasing the pre-coagulation water mist distance and drafting distance could reduce the fiber diameter,improve the crystallinity of the nonwoven,and make the structure of the nonwoven more fluffy with better permeability and liquid absorption.
