我国在20世纪60年代开始由上海合成纤维研究所率先采用干法纺丝工艺小批量生产聚酰亚胺纤维,其用途主要是电缆的防辐射包覆、耐辐射的降落伞绳和带等,不久由于市场原因停产。在70年代中期,上海合成纤维研究所也曾开展了一段聚酰亚胺纤维的研究工作,但该项工作并没有持续下去。国内东华大学和四川大学也开展了聚酰亚胺纤维的研究,但目前仍处于初期阶段。 China began in the 1960s by the Shanghai Institute of Synthetic Fiber took the lead in the use of dry spinning small batch production of polyimide fibers, its use is mainly cable radiation coating, radiation-resistant parachute rope and belt, and soon Discontinued due to market reasons. In the mid-1970s, the Shanghai Synthetic Fiber Research Institute also conducted a research work on polyimide fibers, but the work did not last. China Donghua University and Sichuan University also carried out the study of polyimide fibers, but is still in its infancy.
