Fiber structure development of poly(ethylene terephthalate-co-isophthalate) copolymer polymer,245:124708 2022(Mar. 04) Author:Ren Tomisawa, Mako Okazaki, Toshifumi Ikaga, KyoungHou Kim, Yutaka Ohkoshi, Kazuyuki Okada, Taizo Kabe, Toshiji Kanaya, Hiroo Katsuta, Yoshitsugu Funatsu Abstract:Isophthalic acid copolymerization is generally used to control the properties of polyethylene terephthalate fiber.
To investigate the controlling mechanism, the effects of copolymerization on orientation-induced crystallization
behavior and smectic phase formation after necking were analyzed by acquiring X-ray diffraction images during
the continuous drawing process. Isophthalic acid copolymerization suppressed orientation-induced crystallization
during the spinning and drawing processes. It also decreased the d-spacing and apparent thickness of the
smectic phase, while the integrated intensity and length of the smectic phase were not affected. Furthermore, the
melting point and crystallinity decreased, and the thermal shrinkage of drawn fibers increased, while the birefringence
and tensile strength were unchanged. Almost no change in the molecular orientation and microfibril
