摘　　要：本文对PETG聚酯薄膜的结晶度的影响因素展开了研究,提供了一种DSC测试相对结晶度的比较方法。研究结果表明:随着PETG薄膜中PET含量的提升,薄膜的相对结晶度升高;随着拉伸温度、拉伸比、定型温度的升高和冷却速率的降低,薄膜的结晶度升高。In this paper,the influencing factors of crystallinity of PETG polyester film were studied,and a comparative method of relative crystallinity measured by DSC was provided.The results show that the relative crystallinity of PETG films increases with the increase of PET content.With the increase of drawing temperature,drawing ratio and setting temperature,and the decrease of cooling rate,the crystallinity of the film increases.

关 键 词：拉伸工艺 定型温度 冷却速率 相对结晶度
