摘　　要：采用磷酸/多聚磷酸为溶剂溶解纤维素,制备了具有液晶性能的纺丝原液,相对于粘胶法大大缩短了纤维素溶解时间;并采用液晶纺丝工艺,制得了强度为2.04cN/dtex、模量为90.72cN/dtex的纤维素纤维。Liquid crystalline solutions are made by using the phosphorie/polyphosphoric acid blends as solvent, the dissolving process is more simple than the traditional process. High performance cellulose fibers are made by liquid crystal spinning, fiber strength is up to 2.04 cN/dtex, and fiber modulus is 90.72 cN/dtex.
