摘要

The relation between the microstructural changes in uniaxially stretched polyester (PET) fibers, caused by heat treatment, and quenched in coarse-grain ice were studied. The developing macrostructure was determined using double-beam interferometry. The results clarify the effect of annealing time and temperature with different draw ratios on the structure of PET fibers. Further, the optical results were used to calculate an optical orientation function and an optical orientation angle of drawn, quenched PET fibers.
