| 摘 要： | 拉伸取向是合成纤维生产过程中的重要环节,几乎所有的合成纤维都须要经过拉伸过程。至目前为止,对高聚物本体结晶过程的研究已有了很多的工作,但有关拉伸取向后的纤维结晶过程却研究得很少.聚对苯二甲酸乙二酯的分子链比较刚性,当它从熔融状态骤冷淬火时容易得到完全透明的非晶态聚合物(薄膜或纤维).有许多工作业已证实,

| Abstract: | The kinetics of crystallization of undrawn and drawn (300%) polyethylene tereph-thalate fibres has been studied dilatometrically. The experimental curves conform to Avrami's equation, with n equal to 2.8 and 1.2 for the undrawn and drawn fibres respectively. The crystallization rate is significantly decreased by stretching and the rate is slower, the greater is the molecular chain orientation in the fibre. |
