Abstract (en)

[origin: EP0387395A2] This invention discloses a paper-maker's forming fabric wherein some of the yarns are melt-extruded monofilaments, that are a blend of 60 to 90% by weight of a polyethylene terephthalate, together with 40 to 10% by weight of a thermoplastic polyurethane, which may be an ester or ether-based type. Additionally, it is contemplated that the blend may contain up to 5% by weight of a hydrolysis stabilizer. The high abrasion resistance of these blended monofilaments makes them particularly advantageous for use in replacing the nylon-6 and nylon-66 monofilaments currently used in paper machine forming fabrics. The monofilaments disclosed comprising blends of polyethylene terephthalate and thermoplastic polyurethane are also a feature of this invention.
