Abstract: Infill material for turf having at least one biodegradable biopolymer, at least one vegetable component and at least one plasticizer.

Abstract: A fiber for artificial turf is of the type of monofilament fibers utilized in the manufacturing of artificial turf carpets and which are obtained by extrusion with polyolefins, in polyethylene or another material. The fiber forming the carpets for artificial turf includes a flat rectangular general cross section with its shorter sides rounded. A central part of one of the longer faces of the fiber includes a curved-convex projection, and its other longer face includes a pair of curved-convex projections in a symmetrical position with respect to its central axis, with which a fiber is obtained for artificial turf with high resilience which facilitates its recovery against successive occasional or temporary loads, maintaining its original appearance for a longer time.

Abstract: A method for determining the recovery grade in artificial fiber carpets, such as artificial turf, including obtaining samples of the artificial fiber carpets to be examined in order to capture an image, by a camera and lightbulb under conditions of controlled exposure, of the area of the fibers which will subsequently be subjected to supporting a load. In a certain area of the fibers, in a vertical compressive manner, a load of known mass during a predetermined time is applied, for once the load is released, capturing elevational images, according to the same area of the fibers subjected to the load, at predetermined time intervals. The recovery index of the fibers subjected to analysis based on the area occupied by the fibers is determined before being subjected to the load and after the different predetermined time intervals.
