A method and system for processing and recycling infill material of artificial turf. The invention includes drying extracted infill material through a fluid bed dryer, the fluid bed dryer passes a process gas through a bed of solids via a perforated plate. The dried infill material is processed using a plurality of vibrating screens to remove excessively large or small particles from the infill material. The plurality of vibrating screens may be a set of progressively finer mesh screens. The processed infill material is separated by density. The density of the infill material may be determined by a high intensity, uniform sheet of laminar airflow. The separated infill material is discharged and is ready to be used again in another artificial turf. In one embodiment, the infill material includes at least one of graded sand, granulated styrene-butadiene rubber, cork, organic infill, thermoplastic elastomers, or ethylene propylene diene monomers.

The invention relates to a wear-resistant artificial turf fiber made of the following raw materials by weight: 60 to 95 parts of matrix resin, 1 to 10 parts of wear-resistant masterbatch, 1 to 10 parts of color masterbatch, and 2 to 5 parts of age resister; and the wear-resistant masterbatch contains silicone powder. The wear-resistant artificial turf fiber has a greatly improved wear resisting property, thereby being suitable for places such as schools and the like where the wear-resistant artificial turf fiber is required to be used frequently for a long time. The wear-resistant artificial turf fiber has the advantages that the preparation method is simple; and the cost is low.

The invention discloses an enhancing type artificial turf fibre and a preparing method thereof which belongs to the artificial turf technique field. Fibre intension and flexible of the enhancing type artificial turf fibre are increased greatly and is suitable for occasion with great intensity movement and vehement that can reduce probability of influencing movement caused by turf fibre hurting. The enhancing type artificial turf fibre is composed of matrix resin, enhancing master batch and functional material that each component has weight percentage as follows: 60-94% matrix resin, 5-30% enhancing master batch and 0.1-10% functional material.

Artificial turf for use with an artificial turf system, which may also include a base layer and a support layer. The artificial turf comprising a backing supporting pile tufts of between ¼″ to 4″ in length, in position on its upper surface. The backing may comprise a porous synthetic foam or backing sheet. A filler of particles shaped to have no sharp edges and of substantially equal size are interspersed over the backing and about the tufts up to at least half thick length. The artificial turf substantially retains its resiliency, porosity and equal density throughout.

The present invention provides an artificial turf runway surface suitable for supporting take off, landing and taxiing of aircraft. The turf system cures many of problems and pitfalls associated with natural sand or grass systems, such as rutting, bare spots, erosion, unevenness, standing water as well as other problems associated with natural grass airstrips. The synthetic surface also removes nesting materials and food and thereby dissuades birds and other animals from landing and congregating thereon. The system includes a synthetic covering, such as an artificial turf covering, one or more sheeting or flow through membranes, a compacted rock base suitable for supporting the aircraft when landing, tacking off and taxiing.

The invention provides a novel artificial turf, a method for manufacturing the same and a recycled material prepared from the artificial turf through recycling. The artificial turf comprises grass fiber, grass bottom part and back rubber, wherein the grass fiber and the grass bottom part are mainly made from polyethylene and polypropylene respectively; and the back rubber is made from ethylene vinyl acetate copolymer resin (EVA) as a main material together with a filler, tackifying resin, a conditioning agent, a plasticizer, an antioxidant and the like which are added into the main material. The artificial turf is made by adhering the back rubber to the grass bottom part provided with the grass fiber; and the adhesion can be achieved in two modes: the first mode is to make the back rubber into a thin film firstly and then adhere the back rubber to the grass bottom provided with the grass fiber; and the second mode is to make the back rubber into a thin film through casting and adhere the thin film to the grass bottom provided with the grass fiber simultaneously. The artificial turf can be recycled integrally to obtain a useful recycled composite material, so as to eliminate environmental pollution and reduce the recycling cost.
