Artificial Turf System

Abstract

The invention relates to an artificial turf system which includes a backing layer having in use a top side and a bottom side; a plurality of grass yarns tufted through the backing layer to extend at the top side of the backing layer; and a polymeric foam layer arranged on the top side of the backing layer. The plurality of grass yarns extend through the polymeric foam layer. The invention also relates to a method for manufacturing an artificial turf system.

1 . An artificial turf system comprising:
 a backing layer having in use a top side and a bottom side;   a plurality of grass yarns tufted through the backing layer to extend at the top side of the backing layer; and   a polymeric foam layer arranged on the top side of the backing layer,   wherein the plurality of grass yarns extend through the polymeric foam layer.   
     
     
         2 . The artificial turf system according to  claim 1 , wherein the polymeric foam layer comprises a gel foam. 
     
     
         3 . The artificial turf system according to  claim 1 , wherein the polymeric foam layer comprises embedded filler particles, such as rubber particles, fibers or plastic particles. 
     
     
         4 . The artificial turf system according to  claim 1 , wherein the thickness of the polymeric foam layer is between 1 mm and 40 mm. 
     
     
         5 . The artificial turf system according to  claim 1 , further comprising a plurality of secondary texturized fibers arranged on the top side of the backing layer. 
     
     
         6 . The artificial turf system according to  claim 1 , further comprising a coating layer arranged on the bottom side of the backing layer for fixating the grass yarns. 
     
     
         7 . The artificial turf system according to  claim 1 , further comprising a padding layer, such as a foam layer, arranged on the bottom side of the backing layer. 
     
     
         8 . A method for manufacturing an artificial turf system according to  claim 1 , wherein the method comprises the steps:
 providing a backing layer, for example a fabric web;   providing a continuous polymeric foam layer on one side of the backing layer; and   tufting grass yarns from the other side of the backing layer through the backing layer and through the continuous polymeric foam layer.   
     
     
         9 . The method according to  claim 8 , wherein the continuous polymeric foam layer is applied in a liquid state to the backing layer and subsequently polymerized.
