Abstract: The invention relates to grass yarn for artificial grass coverings being a monofilament. These grass yarns can be provided with ridges to reduce light reflection. The grass yarns can also have a sickle shaped cross section for increased strength. The invention further relates to artificial grass covering comprising a plurality of grass yarns according to the invention.

Abstract: Embodiments of the invention can provide systems and methods for providing an artificial grass system. One embodiment of the invention can provide an artificial grass system with a woven tubular-shaped fabric and tufted artificial turf yarn. For example, the woven tubular-shaped fabric can be made from at least two types of yarn with different shrink characteristics. Various embodiments of the invention can provide improved drainage, shock absorbency, load displacement, and dimensional stability characteristics for an artificial grass or turf system.
