Abstract

Process for the thermal binding of an unwoven fleece (6) comprising synthetic fibres, in which the fleece (6) is brought onto a forming cloth (1) consisting of plastic monofilaments having a melting temperature (t1) higher by at least 80 DEG C than the melting temperature (t2) of the synthetic fibres, hot gas is passed through the fleece (6) and the cloth (1), the temperature of the hot gas being selected as below the temperature (t1), characterised in that the monofilaments forming the cloth (1) consist of polyphenylene sulphide or polyether ether ketone. Cloth (1) for carrying out the method, consisting of monofilaments of polyether ether ketone or of polyphenylene sulphide. Improvement of the quality of the fleece (6) produced, easy use and improved lifetime of the cloth (1).
