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.
