本文通过测定塑化曲线确定聚乙烯(PE)的毛细管挂丝温度范围,测试了挤出原丝和低温区域拉伸丝的力学性能和热收缩行为。结果表明,低压下的毛细管挤出工艺对PE 丝的力学性能影响很小,而低温区域拉伸能大幅度提高原丝的力学性能,产生自增强效应,但热收缩率明显增大。
Through measuring the thermal plastic deformation curve of polyethylene(PE),this paper determined the capillary extrusion temperature range of polyethylene,and measuredthe mechanical properties and heat shrinkage behavior of extruded raw fibres and low te
