Preparation of ultra-high strength polyethylene fibres by gel-spinning/hot-drawing at high spinning rates

  • Published:
Polymer Bulletin Aims and scope Submit manuscript

Summary

The addition of 1 wt.% Al-stearate to the spinning-solution of ultra-high molecular weight polyethylene in paraffin-oil allows takeup speeds of the extrudate of 270 m/min. These as-spun filaments could still be hot-drawn, resulting in a tensile strength of 2.8 GPa. The overall draw ratio's encountered after spinning and hot-drawing are of the order of 1500 suggesting a resemblance between these flow phenomena and superplasticity.
