| 摘 要： | 聚对苯二甲酸丙二醇酯 (PPT)是一种全新的高分子材料。本文采用偏振衰减全反射红外光谱法 ,对不同拉伸工艺条件下的PPT纤维进行了取向研究。结果表明 ,PPT纤维的二向色性比和取向函数都随拉伸速度提高而增大 ,但当拉伸速度高于 2 5 0 0m·min- 1 以后二向色性比基本不变。

| Abstract: | Poly (trimethyleneterephthalate) is a new polymer material. Using polaroid and horizontal ATR accessories combining FTIR spectrometer, the orientation of PPT fiber undergoing different drawing rate was studied. The dichroic ratio and orientation function were determined. The results show that both the dichroic ratio and the orientation function increased with drawing rate, but for dichroic ratio, there was a plateau when drawing rate was above 2,500 m.min-1. |
