Abstract

Processes for preparing ultra-high molecular weight polyethylene (“UHMW PE”) filaments and multi-filament yarns, and the yarns and articles produced therefrom. Each process produces UHMW PE yarns having tenacities of 45 g/denier to 60 g/denier or more at commercially viable throughput rates.
