【Abstract】 The development of PET structure along the spinline in TCS process is investigated by establishing a mathematical model in this paper. Meanwhile, PET-TCS filaments are prepared in TCS spinning machine under the same process conditions as those of the mathematical model involved. The crystallinity and the birefringence of the lake-up yarns are measured by X-ray diffraction method and Senarmont method, respectively. The results show that the calculation results by tliis model are in agreement with the experimental data.更多还原
