PRIMARY BACKING FOR ARTIFICIAL TURF, METHOD FOR ITS MANUFACTURE AND ARTIFICIAL TURF COMPRISING THE PRIMARY BACKING

摘要

A primary backing is provided comprising at least a first 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 optionally a third component having a front surface and a rear surface placed adjacent and plane-parallel to the second component, and wherein - the first component comprises a first two-dimensional material layer, wherein the first two-dimensional material layer comprises an extruded sheet, 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 further two-dimensional material layer comprises an extruded sheet, a non-woven fabric, a woven fabric and/or a two-dimensional layer of macroscopic fibers.
