METHOD FOR THE TREATMENT OF COVERING MATERIALS FOR INTERIOR FITTING PIECES IN PARTICULAR FOR VEHICLE INTERIORS AND INTERIOR FITTING PIECES
The invention relates to a method for the treatment of covering materials for vehicle interior fitting pieces in particular for pieces of trim or vehicle seats, whereby the moisture content of the coating material is temporarily increased, such that the fibres of the coating material are softened in a treatment chamber by the introduction of moisture and then smoothed by the action of a drawing force extending the covering material. The invention further relates to interior fitting pieces treated by the above method, in particular seats, roof linings and trim pieces for motor vehicles.
