PURPOSE: To obtain a product useful for door trims etc. of a car by kneading and molding carpet scraps comprising fiber component and packing resin component at the melting temperature or less of the fiber component and at the melting temperature or more of the packing resin component.

CONSTITUTION: Scraps or defectives of the carpet composed of fibers of polypropylene, nylon, etc. packed by thermoplastic synthetic resin such as polyethylene etc. is used as material. If necessary, the above-mentioned material is broken into meshes of 3W100mm. If further necessary, it is preheated to 100W 160°C. Then, kneading shall be performed as the most important process. The above-mentioned regenerated material is kneaded at the fiber component melting temperature or lower and at the melting temperature of the thermoplastic resin as packing material or more. It is kneaded by a Banbury mixer, a kneading double roll. The kneaded material is formed in calender rolls or a press into the sheet form.
