Artificial turf

Abstract

The object of the invention is to provide an artificial turf which no longer requires the application of a coating on the back of the ground fabric in order to secure the plastic blades of grass. The object of the invention is achieved by providing an artificial turf comprising a ground fabric and a number of plastic blades of grass protruding from the ground fabric in which said turf, as a result of the weave structure, has a pile fixation of at least 15 N.

1 . An artificial turf comprising a ground fabric made from synthetic ground warp yarns and synthetic weft yarns and a number of plastic blades of grass protruding from the ground fabric, wherein said turf, as a result of the weave structure, has a pile fixation of at least 15 N. 
   
   
       2 . The artificial turf as claimed in  claim 1 , characterized in that said turf, as a result of the weave structure, has a pile fixation of at least 30 N. 
   
   
       3 . The artificial turf as claimed in  claim 1 , characterized in that the plastic blades of grass protruding from the ground fabric are tied up in the ground fabric by a W weave in which the plastic blade of grass is tied up at least twice over an intermediate weft yarn between two upright legs of a pile burl. 
   
   
       4 . The artificial turf as claimed in  claim 1 , characterized in that the plastic blades of grass protruding from the ground fabric have a density of at least 1000 tex. 
   
   
       5 . The artificial turf as claimed in  claim 1 , characterized in that the plastic blades of grass protruding from the ground fabric are monofilament yarns which comprise at least six filaments. 
   
   
       6 . The artificial turf as claimed in  claim 1 , characterized in that the plastic blades of grass protruding from the ground fabric protrude at least 20 mm above the ground fabric. 
   
   
       7 . The artificial turf as claimed in  claim 1 , characterized in that said ground fabric comprises binding and tension warp yarns and in that the protruding plastic blades of grass are pile warp yarns. 
   
   
       8 . The artificial turf as claimed in  claim 1 , characterized in that said turf has a fabric density of at least 120 warp yarn portees per meter in the weft yarn direction. 
   
   
       9 . The artificial turf as claimed in  claim 8 , characterized in that each warp yarn portee comprises two tension warp yarns per ground fabric. 
   
   
       10 . The artificial turf as claimed in  claim 9 , characterized in that said two tension warp yarns are situated on either side of at least one pile warp yarn for each warp yarn portee. 
   
   
       11 . The artificial turf as claimed in  claim 9 , characterized in that pile warp yarns are situated between said two tension warp yarns for each warp yarn portee. 
   
   
       12 . The artificial turf as claimed in  claim 9 , characterized in that only pile warp yarns are situated between said two tension warp yarns for each warp yarn portee. 
   
   
       13 . The artificial turf as claimed in  claim 1 , characterized in that said turf has a weft yarn density of at least 3 weft yarns per cm. 
   
   
       14 . The artificial turf as claimed in  claim 7 , characterized in that said turf, in addition to the grass blade-forming pile warp yarns, also comprises supporting pile warp yarns. 
   
   
       15 . The artificial turf as claimed in  claim 7 , characterized in that said turf, in addition to the grass blade-forming pile warp yarns, also comprises filler yarns. 
   
   
       16 . The artificial turf as claimed in  claim 15 , characterized in that the filler yarns extend mainly in the ground fabric. 
   
   
       17 . The artificial turf as claimed in  claim 1 , characterized in that said turf is woven according to a face-to-face weaving method.
