Abstract: The present application relates to an artificial turf system, comprising an elastic substrate layer, an artificial turf carpet applied on the elastic substrate layer, and a first filler material which is filled into the artificial turf carpet, wherein the first filler material comprises a hydrophobic sand, and the use thereof as sports artificial turf.

Abstract: A device for twisting a flat, fibrillated strip for producing artificial turf is disclosed. The device includes a hollow shaft having a central axis of rotation, a deflecting element that is mounted on the hollow shaft and that has a swing region, and a limiting element that is disposed on the hollow shaft. The hollow shaft allows the strip to be continuously passed through a hollow space of the hollow shaft. The deflecting element includes a swing pivot that is offset from the central axis. When the hollow shaft is rotated around its central axis, the swing region of the deflecting element is swung outward from the central axis to a swung-out position. As a result, the strip is rested against the swing region. When the deflecting element is in its swung-out position, the strip is rested against the limiting element that limits the outward deflection of the strip.

Abstract: An artificial turf has a base layer, a multiplicity of blades fixed to and projecting upward from the base layer, and a mass of infill between the blades and on the base layer. The infill is formed of elongated plastic fibers each having a longitudinally extending inner part of a predetermined first plastic and a longitudinally extending outer part bonded to the inner part and of a predetermined second plastic different from the first plastic.

Abstract: A filament for use in an artificial grass field, wherein the filament has a front and a back surface and at least one of the front surface and back surface includes a plurality of adjacent concave indentations extending generally from a first end to a second end.

Abstract: A method of making a fiber for use in association with an artificial turf system, as well as an artificial turf system having such a fiber. The fiber is made by extruding a fiber, fibrillating the fiber, and storing the fiber, wherein the fiber is not cut longitudinally between the step of extruding the fiber and storing the fiber. After being extruded the fiber may be folded and wrapped with a wrapping yarn.

Abstract: Artificial turf has a base layer, a multiplicity of blades fixed in and projecting upward from the base layer, and a mass of damping material on the base layer and through which the blades project. Each of the blades is at least partially formed of a polyester of terephthalic acid made from waste. The polyester is polyethylene terephthalate (PET) or polybutylene terephthalate (PBT), both from waste. The base layer is a flat primary layer, preferably a textile and preferably consists of plastic, a polyolefin and/or a polyester of terephthalic acid, preferably a polyester of terephthalic acid from waste.
