ABSTRACT:
Carpet material with at least a proportion of uncleaned used carpets is shredded to form a fiber-like wooly mass. The carpet material contains a thermoplastic binder with a low melting point, for example polypropylene, which can be derived from the used carpets or be added. On at least one side of the carpet material, a cover layer of wood chips is provided. The carpet material, together with the layers of the adhesive-coated wood chips which form the cover layers, is compressed to form the molded part or panel, at a temperature which lies above the plasticizing point of the thermoplastic binder, but below the plasticizing point of any other thermoplastic components of the carpet material.
