Dynamics Model and Simulation of Polyethylene Terephthalate (PET) Hollow Fiber

On the basis of melt-spinning, the dynamics model of polyethylene terephthalate (PET) hollow fiber is established. The effects of spinning conditions on hollow ratio are discussed and verified. Because of the different quenching conditions, there exist differences of the hollow ratio and the vitrification distances between different cycles.The important role of the quenching conditions on the meltspinning of PET hollow fiber is also mentioned.
