A DRAWN POLYESTER YARN HAVING A HIGH TENACITY,A HIGH INITIAL MODULUS AND A LOW SHRINKAGE

摘要

The instant invention is directed to a drawn polyester yarn. This yarn is characterized by an initial secant modulus greater than 150 grams per denier/100%. The yarn may be further characterized by either a shrinkage of less than 8% or a tenacity of greater than 7.5 grams per denier. Alternatively, the yarn is characterized by a tenacity of at least 10 grams per denier, an initial modulus of at least 120 grams per denier/100% and a shrinkage of less than 8%.
