| Remarks： |
Abstract: According to the basic principle of melt spinning，the dynamic model of flat fiber was deduced in detail. The effect of spinning technology conditions on fiber shaped degree was simulated by using the established model. The simulation results show that the shaped degree is decreasing when the spinning temperature and intrinsic viscosity are increasing；the spinning speed has little effect on the shaped degree when the pump mass throughput is constant; the shaped degree is increasing with the increasing of pump mass throughput when the spinning speed is constant; the cross air blow conditions have much effect on the shaped degree; the scope of shaped degree is increasing when the aspect ratio of spinneret hole is increasing; the shaped degree has obvious decreasing tendency in the small zone of spinning path and this decreasing became gently when the pump mass throughput is increasing.
