【Abstract】 In this paper,the optical anisotropy of PET/PTT self-crimp fiber is observed and investigated using polarized optical microscopy(PLM).By the comparisons to PET and PTT single-component model fibers,the interference patterns and birefringence of PET/PTT fiber are analyzed and calculated with the aim to correlate to the crimp behavior of PET/PTT bicomponent fiber.更多还原
