摘要
采用熔融共混纺丝的方法 ,以易水解聚酯 (EHDPET)为一组分与 PP经单螺杆共混纺丝制得试样 ,测试了共混组分的流变性能。以 SEM为研究手段 ,通过改变喷丝孔长径比及纺丝温度 ,讨论了熔体弹性对共混纤维相转变的影响规律。加大喷丝孔长径比 ,适当提高纺丝温度有利于使
Easy hydrolytic degradation polyester(EHDPET) and PP were melt\|spun with a single screw. The rheological behavior of PP/EHDPET blends was determined by means of SEM. The effect of melt elasticity on phase inversion of blend fibers was discussed at different spinneret L/D ratio and spinning temperature. Higher L/D ratioes and spinning temperatures was helpful for the formation of PP disperse phase at higher composition ratioes.
