聚苯撑苯并二噻唑的纺丝工艺研究

Studies on the spinning technology of Poly-(p-phenylenebenzothiazole) fibers

对聚苯撑苯并二噻唑（PBZT）的纺丝采用了“干喷湿纺”新技术，连续纺出了高强度、高模量的PBZT纤维。研究了PBZT的溶液浓度、PZT分子量、纺丝时空气层高度、纺丝温度和拉伸比对所纺出PBZT纤维力学性能的影响，找到了最佳纺丝工艺条件。

The high strength and high modulus fibers of poly (p-phenylenebenzothiazole )(PBZT) had been spinned by the dry-jet wet-spinning technology The factors that affect the mechanics properties of PBZT fibers had been studied.
