In this paper, the effect of the jet stretch ratio on the extrusion die-swell effect (Barus effect) of polyacrylonitrile spinning dope and the aggregating structure and properties of the protofibers was systematically analyzed.
研究了凝固负拉伸对聚丙烯腈(PAN)纺丝液的膨胀效应、初生纤维聚集态结构和性能的影响,初步揭示了膨胀效应和凝固取向的产生机理及其对初生纤维结构与性能的影响;指出溶剂与水之间的传质速率差是控制初生纤维结构进而控制其性能的最关键因素,它决定了原液细流表面凝固层的组成及结构,而凝固速率反映了凝固层的生长速度。
