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

摘要

A yarn for strands of an artificial turf ground cover, including a tape filament (4) having a core layer (8) and two outer layers (9) of a different material than the core layer (8), each on one of two opposite sides of the core layer. The core layer (8) contains at least polyester or polyolefin material, and the outer layers (9) contain high-density polyethylene. An artificial turf ground cover and a playing field including such a yarn and a method for producing such a yarn are also described. The high-density polyethylene has a relatively small coefficient of friction with the human skin and the yarn has a good shape recovery after deformation in spite of containing HDPE in outer layers.
