Zusammenfassung: | 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.
Un proceso para preparar hilos de múltiples filamentos de poli(alfa-olefina) de peso molecular ultra elevado (UHMWPO) que tienen propiedades mejoradas de tensión a productividad elevada. El proceso incluye estirar un hilo de solución, luego estirar un hilo de gel y luego estirar un hilo seco continuamente en secuencia para formar un hilo parcialmente orientado, enrollar el hilo parcialmente orientado, desenrollar el hilo; estirar el hilo parcialmente orientado para formar un hilo altamente orientado, enfriar el hilo altamente orientado bajo tensión y enrollar el hilo altamente orientado. |
