摘要
Disclosed is a method of forming multifilament polyolefin yarns and yarns formed according to the disclosed method. The yarns can be polypropylene yarns and can exhibit any of a high modulus, high tenacity, and a unique crystalline structure for multifilament polyolefin yarns. The process can generally include extruding a polymeric melt including the polyolefin at a relatively high throughput and low spinline tension and quenching the filaments in a liquid bath prior to drawing the fiber bundle at a relatively high draw ratio, for example greater than 10, in some embodiments.
