摘要

<正> In this paper

the microstructure change of one step-draw PET fiber has been studied byvarious methods

such as

Laser Raman Microscope

Wide-angle X-ray

Density-gradient andPolarizing Microscope. The computer has been used to resolve overlapped bands in the Ramanspectra. Then the band changes have been correlated with trans

gauche and stressed trans-conformations indicated by a conformational index. Based on these indices

the relationshipbetween the conformation change of glycol units in the fiber structure and the macromechanicalproperties of fiber is expounded.
