Yarn for an artificial turf ground cover, artificial turf ground cover and playing field including such a yarn and method for producing such a yarn

An artificial turf ground cover including a substrate sheet and strands fastened to the substrate sheet and projecting upwardly from the substrate sheet, wherein

• the strands are formed of a yarn including a tape filament having a core layer and two outer layers of a different material than the core layer and co-extruded with the core layer, each on one of two opposite sides of the core layer,
• the core layer contains polyester and/or polyolefin material,
• the outer layers contain high-density polyethylene, and
• the material of the tape filament has been stretched in longitudinal direction.

A playing field including a ground layer and an artificial turf ground cover including a substrate sheet and strands fastened to the substrate sheet and projecting upwardly from the substrate sheet, wherein

• the strands are formed of a yarn including a tape filament having a core layer and two outer layers of a different material than the core layer and co-extruded with the core layer, each on one of two opposite sides of the core layer,
• the core layer contains polyester and/or polyolefin material,
• the outer layers contain high-density polyethylene, and
• the material of the tape filament has been stretched in longitudinal direction, the turf ground cover covering the ground layer.

A method for producing a yarn for forming strands of an artificial turf ground cover, including

• extruding a core layer of at least polyester or polyolefin material,
• extruding outer layers containing high density polyethylene,
• bringing the layers in a multilayer configuration with the core layer between two of said outer layers,
• stretching the material of the multilayer configuration in longitudinal direction at a stretching ratio of 1:3-1:6.
