Abstract
An imitation leather including a three-dimensional textile supporting material and a PVC-based covering that is applied to one side of the supporting material and includes three successively applied layers. The first layer of which is applied directly to the supporting material without an adhesion-promoting glue layer, the second layer of which is embodied as an intermediate layer and applied directly to the first layer and the third layer of which serves as a top layer and is applied directly to the second layer. This invention also discloses a method for producing such an imitation leather and an interior component of a motor vehicle having a visible surface that is composed of such an imitation leather.
Claims20
A method for producing an imitation leather, having a three-dimensional textile supporting material (1) and a covering (2) applied to one side of the supporting material (1), in which the covering (2) is polyvinyl chloride-based and has three successive layers (21), (22), (23) each comprising polyvinyl chloride, and including the steps of:
- applying the third layer (23) of the covering (2), which forms a subsequent top layer, in a paste form onto a removable backing and subsequent drying of the third layer (23);
- applying the second layer (22) of the covering (2) as an intermediate layer onto the dried third layer (23) and subsequent drying of the second layer (22);
- applying the first layer (21) of the covering (2) in the paste form onto the dried second layer (22);
- placing a crocheted spacer fabric as the textile supporting material (1) directly onto the first layer (21) while the first layer (21) is in the paste form and without interposition of an adhesive layer between the crocheted spacer fabric and the first layer (21), and subsequent drying of the first layer (21), the crocheted spacer fabric including a first fabric layer (10) spaced apart from and connected to a second fabric layer (12) by strands of pile yarn (11), and each of the first fabric layer (10) and the second fabric layer (12) having smooth-surfaced outsides without protruding threads;
- and
- detaching the third layer (23) from the backing.
