Abstract
This invention relates to an article of paper machine fabric used in a papermaking machine which is essentially a fibrous structure comprising monofilament yarns wherein the monofilament yarns comprise a polyester comprising from about 85 to 100 mole % of 2,6-naphthalenedicarboxylic acid and about 85 to 100 mole % of ethylene glycol or 1,4-cyclohexanedimethanol, based on the total mole percentage for the glycol portion and for the acid portion of the polyester each equalling 100 mole %. This invention provides good resistance to hydrolytic and dry heat degradation, good dimensional thermal stability, and good resistance to deformation.
