Abstract:
The invention refers to a cover nonwoven for an interior lining for a vehicle, comprising a nonwoven fabric consisting of at least two nonwoven layers, a first nonwoven layer and a second nonwoven layer, wherein a first outer surface of the nonwoven fabric is formed by a surface of the first nonwoven layer and a second outer surface of the nonwoven fabric is formed by a surface of the second nonwoven layer, and wherein the first nonwoven layer and the second nonwoven layer are inseparably bonded on the entire surface.
According to the invention, the first nonwoven layer is formed of a rough polypropylene spunlaced nonwoven and the second nonwoven layer is formed of a dense polypropylene spun-bonded nonwoven, wherein the first outer surface of the nonwoven fabric is suitable for the application of a pressure-sensitive adhesive, and wherein the second outer surface of the nonwoven fabric has hydrophobic properties.
