Abstract: Monofilaments having high abrasion resistance and dimensional stability and low slide friction, textile fabrics composed thereof and use thereof Disclosed is a polyester monofilament comprising a) 60 to 85 wt.-% of a polyester raw material selected from the group of polyethylene terephthalate, of polyethylene naphthalate, of to polyethylene terephathalate modified with dicarboxylic acid, of polyethylene naphthalate modified with dicarboxylic acid, or of combinations thereof, b) 14.4 to 30 wt.-% of a thermoplastic elastomeric block copolymer, c) 0.05 to 10 wt.-% of a polycarbonate, and d) 0.1 to 10 wt.-% of a carbodiimide stabilizer, wherein the quantities are based on the total amount of the monofilament. The disclosed monofilaments can be preferably used for the manufacture of paper machine clothing and are distinguished by high hydrolytic stability, abrasion resistance and dimensional stability as well as by a very low slide friction.
