The invention relates to recyclable textile floor coverings for motor vehicles with a multi-layer structure and processes for their preparation. In particular, recyclable textile floor coverings for motor vehicles with a multi-layer structure include a foam layer, a separation layer, a heavy layer, and a textile carpet, wherein the adhesiveness of the separation layer with respect to the heavy layer is different than the adhesiveness of the separation layer with respect to the foam layer. In another embodiment, the separation layer is separably bonded to the heavy layer by spot bonding and/or is separably bonded to the foam layer by spot bonding. The separation layer allows separate recycling of the foam layer on one hand and the textile carpet including the heavy layer on the other hand.

The subject matter of the present invention is a process for producing decorable moulded parts made of plastic materials, whereby an extrudable thermoplastic material is injected or pressed behind a non-dried or non-cured flat decorative layer or paint layer. In a preferred embodiment, the decorative layer or paint layer is powder coated, whereby the support film, the paint layer and the thermoplastic material are coextruded together. This process allows decorable moulded parts having complex geometrical shapes to be manufactured.

A process for the preparation of a textile floor covering for a motor vehicle includes the steps of wiper blade coating a mixture (2) of foam off-cuts and a self-curing binder in a matrix form (1) of a floor panel of a motor vehicle in a desired layer thickness profile; pressing onto the mixture a textile carpet (4) provided with a heavy layer (3) thereby adjusting the desired density of the foam off-cuts; and curing the binder during the pressing to form an absorption foam backing layer and to bond the backing layer to the heavy layer. In an alternative embodiment, the absorption foam backing layer is first formed and then adhesively bonded to the heavy layer. By means of the invention a strong bond between the backing layer and heavy layer, and a uniform density and distribution of the foam off-cuts is obtainable, whereby a high degree of acoustic dampening efficiency is achieved.
