ABSTRACT OF THE DISCLOSURE A high temperature copolyester monofilament exhibits enhanced knot tenacity and is formed from the extrusion of a polymer blend of a copolyester resin and a fluoropolymer resin. Additives such as thermal stabilizers may be added tothe polymer blend. The polymer blend may be extruded in the presence of other additives such as a hydrolytic stabilizer. The monofilament exhibits a higher average knot tenacity, a higher minimum knot tenacity, a narrower knot tenacity range and lower standard deviation as compared to standard high temperature copolyester monofilaments. A dryer fabric comprises a plurality of woven copolyester monofilaments having enhanced knot tenacity, the monofilaments comprising a polymer blend of copolyester resin and fluoropolymer resin, and may further include thermal stabilizers and hydrolytic stabilizers.
