  • Split resistant fibre
    Patent number: 11939730
    Abstract: A fibre for use in artificial turf has an elongate cross-sectional shape defining a first face and a second face that meet at side edges of the fibre. The first and second faces having respective first and second ridges that are offset with respect to each other, such that the cross-sectional shape is 2-fold rotationally symmetric with no reflectional symmetry. The fibre may be an extruded monofilament and shows improved resilience over symmetrical fibres of similar dimensions.
    Type: Grant

  • Artificial turf system
    Patent number: 10844553
    Abstract: An artificial turf system comprises a resilient layer, an artificial grass layer comprising a substrate and pile fibers 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 fibers. The smooth, hard granules provide improved characteristics in terms of foot release.
