High tenacity, oblong cross-section monofilaments having a modification ratio of at least 4.4

摘要

A monofilament of oriented thermoplastic polymer having an oblong cross-section defining a width-to-thickness ratio for the monofilament greater than about 2.0 and a modification ratio not less than 4.4, a denier greater than about 1000, a tenacity of greater than about 7.5 g/d, and a modulus greater than about 45 g/d.
