FLASH-SPINNING POLYMERIC PLEXIFILAMENTS |
摘要 |
An improved process is provided for flash-spinning plexifilamentary film-fibril strands of a fiber-forming polyolefin from a C4-7 hydrocarbon/co-solvent spin liquid that, if released to the atmosphere, presents a greatly reduced ozone depletion hazard, as compared to the halocarbon spin liquids currently-used commercially for making such strands. The resulting plexifilamentary film-fibril strands have increased tenacity and improved fibrillation compared to strands flash-spun from 100% hydrocarbon spin liquids.
