摘　　要：采用声速法、X射线衍射、沸水收缩率、密度分析等分析检测手段,研究了湿纺凝固浴浓度和温度对初生纤维聚集态取向和性能的影响。研究表明:凝固浴浓度为70%,凝固浴温度为50℃,初生纤维的总体取向、晶区和非晶区取向较大,并且具有圆形的截面、较大的体密度。The effect of coagulation bath concentration and temperature on the congregating structure and properties of PAN nascent fibers were systematically analyzed by means of the sonic velocity method, X-ray diffraction, the boiling-water shrinkage ratio, density analysis and so on. The results showed that the nascent fibers could be produced with better properties, including bigger overall and crystalline region orientation, higher noncrystalline region orientation, bulky density, circular cross-section.
