A primary backing having a component having a front surface and a rear surface, a second component having a front surface and a rear surface placed adjacent and plane-parallel to the first component, and an optional third component having a front surface and a rear surface placed adjacent and plane-parallel to the second component, wherein the first component comprises a two-dimensional material layer, an extruded sheet, and a non-woven fabric and/or a woven fabric. The second component comprises a three-dimensional structure, wherein the three-dimensional structure is build-up from macroscopic thermoplastic fibers, the fibers cross one another at crossing points and are thermally bonded to one another at their crossing points, and the third component comprises a further two-dimensional material layer, wherein the material layer comprises an extruded sheet, a non-woven fabric, a woven fabric and/or a two-dimensional layer of macroscopic fibers.
A primary backing comprising
A process according to claim 20, wherein the further two-dimensional structure of the third component is manufactured by
The process according to claim 20, wherein the three-dimensional structure of the second component and the two-dimensional structure of macroscopic fibers of the third component are formed simultaneously in an integrated process step (ips I).
