Artificial turf and method for producing a turf of this type

Abstract

The present invention relates to an artificial turf ( 1 ) and a method for producing an artificial turf ( 1 ) comprising a ground fabric made from synthetic ground warp yarns and synthetic weft yarns and a number of plastic blades of grass ( 2 ) protruding from the ground fabric in the shape of pile burls which succeed one another in the warp direction and which each comprise two pile legs ( 2 a ), in which at least three and at most nine weft yarns ( 3 ) are inserted between two successive pile legs ( 2 a ). In particular, each pile leg ( 2 a ) is tied up around a different weft yarn ( 3 ) which are both situated between the two pile legs. As the distance between the two pile legs of a pile burl is only half that of the distance between the pile legs during tufting, the material consumption in terms of plastic grass blade yarn will be greatly reduced. In addition, artificial turf ( 1 ) of this type has the advantage that the pile burls and in particular the plastic blades of grass are evenly distributed across the fabric.

1 . An artificial turf ( 1 ) comprising a ground fabric made from synthetic ground warp yarns and synthetic weft yarns and a number of plastic blades of grass ( 2 ) protruding from the ground fabric in the shape of pile burls which succeed one another in the warp direction (K) and which each comprise two pile legs ( 2   a ), wherein at least three and at most nine weft yarns ( 3 ) are inserted between two successive pile legs ( 2   a ). 
   
   
       2 . The artificial turf ( 1 ) as claimed in  claim 1 , characterized in that the plastic blades of grass ( 2 ) protruding from the ground fabric are tied up into the ground fabric by means of a W weave. 
   
   
       3 . The artificial turf ( 1 ) as claimed in  claim 1 , characterized in that, for each pile burl, the plastic blade of grass ( 2 ) is tied up over at least two weft yarns ( 3 ) which are situated between the pile legs ( 2   a ) of this pile burl on the side of the artificial turf of the fabric. 
   
   
       4 . The artificial turf ( 1 ) as claimed in  claim 1 , characterized in that, for each pile burl, the plastic blade of grass ( 2 ) is tied up over three weft yarns ( 3 ) which are situated between the pile legs ( 2   a ) of this pile burl on the side of the artificial turf of the fabric. 
   
   
       5 . The artificial turf ( 1 ) as claimed in  claim 1 , characterized in that the pile legs ( 2   a ) of adjacent rows of piles are offset with respect to one another. 
   
   
       6 . The artificial turf ( 1 ) as claimed in  claim 1 , characterized in that said turf ( 1 ) is woven according to a face-to-face weaving method. 
   
   
       7 . A method for producing an artificial turf ( 1 ) comprising a ground fabric and a number of plastic blades of grass ( 2 ) protruding from the ground fabric, characterized in that a bottom and a top fabric are woven according to a face-to-face weaving method, in which the fabrics are made from synthetic weft yarns ( 3 ), synthetic ground warp yarns and grass blade-forming pile warp yarns ( 2 ) by means of which pile burls with in each case two pile legs ( 2   a ) are formed alternately in both fabrics, in which, in each fabric, each pile leg in a row in the warp direction (K) is separated by at least three and at most nine weft yarns ( 3 ) from the next pile leg of a plastic blade of grass ( 2 ) in this row. 
   
   
       8 . The method as claimed in  claim 7 , characterized in that the purpose of said method is to produce an artificial turf ( 1 ) as claimed in  claim 1 .
