Fiber for artificial turf

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.

1 . A fiber for artificial turf, being of the type of monofilament fibers utilized in the manufacturing of artificial turf carpets and which are obtained by extrusion in polyethylene or another material, the fiber comprising:
 a flat rectangular general cross section with shorter sides thereof rounded;   a central part of one of longer faces of the fiber comprising a curved-convex projection, and a second of the longer faces comprising a pair of curved-convex projections in a symmetrical position with respect to a central axis of the fiber.   
     
     
         2 . The fiber for artificial turf, according to  claim 1 , wherein the fiber forming the carpets for artificial turf has a height of approximately 60 mm. 
     
     
         3 . The fiber for artificial turf, according to  claim 1 , wherein the fiber forming the carpets for artificial turf has a width of approximately 1400 μm. 
     
     
         4 . The fiber for artificial turf, according to  claim 1 , wherein the thickness of the fiber forming the carpets for artificial turf in the central part of the curved-convex projections is the same for all fibers in the central part. 
     
     
         5 . The fiber for artificial turf, according to  claim 1 , wherein the thickness of the fiber forming the carpets for artificial turf in the central part of the curved-convex projections is of approximately 270 μm. 
     
     
         6 . The fiber for artificial turf, according to  claim 4 , wherein the thickness of the fiber forming the carpets for artificial turf in the central part of the curved-convex projections is of approximately 270 μm.
