Study on the influencing factors of crystallinity of PETG polyester film
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.
