Abstract

A paper machine dryer fabric in which at least a portion of the component yarns are monofilaments comprised of a copolymer of dimethylolcyclohexane, terephthalic acid, and isophthalic acid, and an effective amount of a hydrolysis stabiliser. The molar ratio of terephthalic acid to isophthalic acid used in preparing the copolymer is about 83:17, and the copolymer has an intrinsic viscosity which is greater than about 0.75 dL/g. The copolymer imparts to the monofilaments an increased resistance to hydrolytic degradation and improved knot properties, in comparison to other known polymers used in dryer fabrics. Low density polyethylene may optionally be added to the copolymer to increase the resistance of the monofilaments to surface contamination and soiling.
