This invention describes a drawn multifilament yarn having high modulus and high tenacity properties. The drawn multifilament yarn has at least three filaments, each filament including a polyolefin and each filament having a denier of less than about 300 grams/9000 meters, the drawn multifilament yarn having been drawn at a draw ratio of greater than about 6 and the drawn multifilament yarn having a modulus greater than about 40 grams/denier, wherein at least one of the filaments possesses greater than about 80% crystallinity according to WAXS measuring techniques. |
