Abstract
A process for preparing ultra-high molecular weight poly(alpha-olefin) (UHMWPO) multi-filament yarns having improved tensile properties at higher productivity. The process includes drawing a solution yarn, then drawing a gel yarn and then drawing a dry yarn continuously in sequence to form a partially oriented yarn, winding up the partially oriented yarn, unrolling the yarn, drawing the partially oriented yarn to form a highly oriented yarn, cooling the highly oriented yarn under tension and winding up the highly oriented yarn.
