Study on gel-spinning process of ultra-high molecular weight polyethylene
An ultra-high molecular weight polyethylene (UHMW-PE) fiber was prepared by gel spinning using general kerosene as the solvent and gasoline as the extraction solvent. The process of the phase separation of gel as-spun, spun under various spinning conditions, was investigated. Its extracting and drying process were also studied. The results reveal that the gel as-spun, spun under a lower spin draft and a lower spin quenching temperature, extracted in times and dried under free-shrinkage, exhibits a good afterdrawability that eventually endows the fiber with excellent mechanical behaviors.
