The proposed material is produced using natural and/or man-made fibres and thermoplastic threads formed into a mat by carding and consolidated by the application of pressure and heat. The mat with the low melting point, thermoplastic, pref. poly-ethylene or poly-propylene, threads is worked by two or more carding machines to form a non-homogenous structure, with the highest concentration of low melting point threads in the top layer. The mat is then moved to a drying cabinet and the polymer threads are cut up by a hot air jet. The mat is then pressed and cut to size, or in some cases heated using infra-red radiation at approx. 140 deg. C. A decorative layer is added using a binder material and pressure. Alternatively the correctly sized mat is shaped in a press-tool
