Abstract

Abrasion-resistant polyester mixture with enhanced consistency of processing, monofilaments therefrom, and production and use thereof. Described is an abrasion-resistant polyester mixture with enhanced consistency of processing, comprising a thermoplastic polyester and a thermoplastic polyurethane with or without customary nonpolymeric additives, the mixture of said polyester and said polyurethane having a melting point between 200.degree. and 230.degree. C. as are monofilaments made of said mixture. Also described are the production of this abrasion-resistant polyester mixture, the production of monofilaments therefrom, and their use for producing paper machine wire cloths.
