Definitions

  • the following invention relates to a fiber for artificial turf, being of the type of fibers utilized in the manufacturing of artificial turf carpets, by weaving the fibers, such that the essential object is to obtain a fiber with some resilient characteristics which make it recover its vertical position after being compressed, occasionally or temporarily, maintaining its original appearance for a long time.
  • the extruded monofilament fiber manufactured with polyolefins in polyethylene has a certain cross section, and the height of the fibers forming the turf carpets present a certain length.
  • the fibers forming the artificial turf carpet are allowed to recover their vertical position after being subjected to successive loads.
  • a fiber for artificial turf is described, of special application in manufacturing artificial fiber carpets for turf in the installation of fields for different sports, such as soccer, golf, rugby, or hockey.
  • the fiber for artificial turf is equally applied to other uses, such as gardens, access roads, or decoration.
  • the monofilament fibers should have high resilience which makes them recover their vertical position after having been occasionally or temporarily compressed over time, preventing the fibers staying tilted over the ground.
  • a synthetic turf having a substrate and a plurality of turf filaments made of synthetic polymer anchored to the substrate, said filaments having a diamond-shaped cross section, with a longitudinal axis along from one end to another end, and a lateral axis located in the middle, so that the thickness of the filament gradually decreases from said lateral axis, substantially, symmetrically and smoothly over the longitudinal axis toward each end.
  • a synthetic turf comprising a turf carpet and some knots projecting therefrom, the knots comprise individual filament strands and at least one shredded strand and, at least, a number of said strands consists essentially of a mixture of high density polyethylene and low density linear polyethylene.
  • an artificial turf filament wherein the filament has, in cross section, a central area and two wing areas in the opposite sides of said central area, and with a divergent orientation, such that an outward protruding head is formed at one side of the divergent areas of the central area, and at the far side from the divergent areas, the central area, has a face which is essentially aligned in the place of said central area and which is merged to the adjacent faces of each wing area.
  • a fiber for artificial turf being of the type of monofilament fibers utilized in the manufacturing of artificial turf carpets, by weaving the fibers and which are obtained by extrusion in polyethylene or another material, such that the fiber for artificial turf presents a flat rectangular cross section with its shorter sides rounded, in the central part of one of its longer faces being provided with a curved-convex projection, and in its other longer face is provided with a pair of projections, equally curved-convex, in a symmetrical position with respect to its central axis.
  • the fiber for artificial turf has a width of approximately 1400 ⁇ m.
  • the fibers for artificial turf which form the carpets have a height of approximately 60 mm.
  • the thickness of the fiber for artificial turf in the central part of the curved-convex projections is the same for all of them, such that in a preferred implementation the thickness of the fiber for artificial turf in the central part of the curved-convex projections is of approximately 270 ⁇ m.
  • FIG. 1 Shows a perspective view of a segment of a fiber for artificial turf, being able to observe the cross section thereof.
  • FIG. 2 Shows a detailed perspective view of some weaved fibers forming the corresponding carpet for artificial turf.
  • FIG. 3 Shows a results table of the recovery index of the fibers, with different cross sections, to be analyzed, with a height of 60 mm, according to the elapsed time of 1, 30 and 240 minutes from its release from a compressive load.
  • FIG. 4 Shows an evolution table of the fibers in their recovery over time of 1, 30 and 240 minutes after their release from a compressive load, according to the recovery index of the analyzed fibers with a height of 60 mm.
  • FIG. 5 Shows a classification table of the analyzed fibers according to a height of 60 mm, according to the elapsed time of 1, 30 and 240 minutes, after their release from a compressive load.
  • the section of the fiber object of the invention has been subjected to an analysis together with three more samples of different sections, so that the cross section of the fiber 1 object of the invention (corresponding to the sample of section 3 ) presents a flat rectangular general shape with its shorter sides rounded, in the central part of one of its longer faces being provided with a curved-convex projection 2 , and in its other longer face is provided with a pair of curved-convex projections 3 in a symmetrical position with respect to its central axis.
  • the special section of the sample 3 based on the curved-convex projections of its longer faces confer it with high resilience, in which the height of the fiber forming the artificial turf carpets collaborates.
  • the fiber 1 for forming artificial turf carpets has a width “D” of approximately 1400 ⁇ m.
  • the thickness “d” of the fiber for artificial turf in the central part of the curved-convex projections is the same in all of them, such that in a preferred implementation is of approximately 270 ⁇ m.
  • fibers 1 forming the weaved bundles of the artificial turf carpet will have a height preferably of 60 mm, although, logically, the height could be another one.
  • the method is specified based on applying to the samples a constant compressive load of 1400 kg during 72 hours, such that, once said time is elapsed, the load is released and images of the same zone are captured after 1, 30 and 240 minutes. Before applying the compressive load, an image has also been taken in order to know and define the total area occupied by the fibers, this value corresponding to 100% of the fibers in their state of equilibrium.
  • the captured images are analyzed for each one of the times and the area occupied by the fibers is calculated, assigning 100% recovery to the initial area occupied by the fibers before applying the load, such that calculating the recovery index is carried out applying the following ratio
  • the results of the recovery index have been obtained for the carpets formed of some fibers with a height of 60 mm, shown in the table of FIG. 3 , after a time of 1, 30 and 240 minutes of being released from the load, being able to observe how the sample of section 3 presents a recovery index of 100% already at 30 minutes of releasing the load.
  • FIG. 4 of the designs the classification of the result obtained from the four analyzed samples is depicted, being able to observe how the fibers of the sample 3 object of the invention are the ones that recover more, having logically, higher resilience.
  • FIG. 5 of the designs the evolution of the recovery index of the four analyzed samples is depicted at a fiber height of 60 mm, being able to observe how the sample 3 object of the invention is the one having a greater recovery index.

  • the fiber 1 for forming artificial turf carpets has a width “D” of approximately 1400 ⁇ m.
  • the thickness “d” of the fiber for artificial turf in the central part of the curved-convex projections is the same for all of them, such that in a preferred implementation is of approximately 270 ⁇ m.
