Embodiment 1

[0030] figure 1 A cross-section of a conventional artificial turf system 1 is shown, comprising a stable base 2 , a base plate 4 , pile fibers 6 and a filling 8 formed of elastomeric rubber particles and a sand layer 7 . Substrate 4 and fluff fibers 6 are from Greenfields TM Slidemax 60 TM Tufted grass system and DS XWR TM Down fiber6. The sand layer 7 is 15mm and the fill 8 has an undefined shape with a Shore A hardness of 60-65 and a grain size of 0.8mm-2.5mm. Turf System 1 of Example 1 is believed to represent the best state of the art artificial turf systems currently available for foot release and slide performance purposes.

Embodiment 2

[0032] figure 2 A cross-section of an artificial turf system 10 according to one embodiment of the invention is shown. The turf system 10 includes a stable base 12 , a resilient layer 13 , a substrate 14 with fluff fibers 16 , a granule layer 17 and a fill layer 18 . According to an embodiment, the elastic layer 13 is Ecocept TM 40mm layer, containing 60% rubber and 40% recycled plastic granules with 14wt.% PU binder. The artificial grass layer was Woven Carpet MX from Greenfields, 50 mm Trimension fibers with fibers of diamond cross section. The fine grain layer 17 is 10mm sand filling, grade 0.2-1.0mm, with 15kg / m 2 Coverage. The packing layer is composed of PE fine particles at a depth of 25mm, with a Shore D hardness of 40, good roundness, with medium sphericity, 3.8mm average diameter and 12.5kg / m 2 Coverage.

Abstract

An artificial turf system comprises a resilient layer,an artificial grass layer comprising a substrate and pile fibres upstanding from the substrate and an infill layer. The infill layer comprises smooth, hard granules having a mean size of between 1.8 mm and 10 mm disposed on the substrate and interspersed between the pile fibres. The smooth, hard granules provide improved characteristics in terms of foot release.

Description

technical field [0001] The present invention relates to artificial turf systems, and more particularly to turf systems provided with an infill imparting improved playing characteristics. The invention also relates to an improved padding material and the use of this padding material to achieve improved lateral foot release properties. Background technique [0002] Artificial turf systems are well known for a variety of athletic and aesthetic purposes and have evolved to their current form over many generations. In general, while perhaps surpassing in some respects, such systems manage to achieve the same properties as their natural counterparts, at least in terms of behavioral predictability. [0003] A typical third generation turf system includes a substrate layer having an upper surface and a fill layer of soft granules disposed between fibers. The backing layer may consist of a woven fabric in which tufts adorn the artificial grass fibers to provide the pile fibers orie...
