    Abstract: The invention relates to a multi-layer, sound-absorbing lightweight component, in particular for motor vehicles. The object of the present invention is to create a sound-absorbing component for motor vehicles which is relatively light and at the same time has a high or even improved acoustic effectiveness compared to conventional components of this type. To achieve this object, a multi-layer component is proposed which has an air-permeable cover layer (17) and at least one air-permeable fleece layer (10″) of thermoplastic fibres, the cover layer (17) being coupled to the fleece layer (10″) in a sound-permissive manner. The component of the present invention is further characterized in that the fleece layer (10″) has a thickness in a range of 2 to 7 mm for a weight per area unit in a range of 500 to 1,500 g/m2 and is not connected or is only partially connected to a surface area of less than 20% of its surface facing the cover layer (17).

    Abstract: The present invention relates to an improved process for the production of artificial turf, and the improved artificial turf. In accordance with this process, fibers are treated via corona discharge, tufted into a primary backing to form a greige good, and a precoat is applied to the back surface the greige good. Suitable fibers are polyolefins, and suitable precoats are reactive polyurethane mixtures. The fibers may be treated by corona discharge either before they are tufted into the primary backing to form the greige good or after the are tufted into the primary backing. Artifical turfs of the present invention comprise a greige good having fibers tufted into a primary backing, with the fibers being treated by corona discharge either before or after being tufted into the primary backing, and a precoat which is attached by its face surface to the back surface of the greige good.
