Abstract:
A process for drawing essentially diluent-free gel-spun polyethylene multi-filament yarns in a forced convection air oven and the drawn yarns produced thereby, The process conditions of draw ratio, stretch rate, residence time, oven length and feed speed are selected in specific relation to one another so as to achieve enhanced efficiency and productivity. The drawn yarns are useful in armor, composites, fishing line, ropes, sutures, fabrics and other applications.
