Study on HOY Process of Ultra High-speed Spinning

In the paper, characteristics of HOY spinning process was studied, the effect of primary processing parameters on spinning was discussed, and the mechanism of fibers formation and super-molecule structure were researched. The results indicated that the quality of PET chips and the processes of drying, temperature of spinning and hot zone, speed of spinning, total denier and dpf etc, had bigger influence on the spinnability, mechanical property and super-molecule structure.
