| 摘 要： | In this paper the influences of the drawing temperature on physical structures and properties of PET filaments have been studied. The results show that the temperatures of the first-stage drawing will have significant effects on birefringence development of filaments during the second stage drawing, as well as the oriented amorphous filaments change to crystanine-oriented filaments after heat treatment. Increasing temperature of the second-stage drawing can be greatly increasing the crystallinity and decreasing the dry heat shrinkage of the filaments.
