Synthetic Sports Turf Having Lowered Infill Levels

Abstract

A durable and wear resistant synthetic sports field having a plurality of strips having a plurality of fibrillated polypropylene strands tufted within a multilayer backing material. The strands are tufted in a wide variety of pile heights, patterns, gauges, and stitch patterns depending upon end use. A particulate matter infill is introduced onto the strips at a depth between about 10% and 50% of the overall height of the strands.

1 . A synthetic turf field comprising:
 a substrate;   a plurality of strips of synthetic turf laid onto said substrate, each of said plurality of strips including a plurality of synthetic strands tufted through a backing layer and extending a predetermined height above said backing layer; and   a layer of particulate matter infill coupled onto said plurality of strips and interspersed within said plurality of synthetic strands, wherein the depth of said layer is between about 10% and about 50% of said predetermined height.   
     
     
         2 . The synthetic turf field of  claim 1 , further comprising:
 a shock resistant layer coupled between said substrate and said backing layer.   
     
     
         3 . The synthetic turf field of  claim 1 , wherein said layer of particulate matter comprises hard particles. 
     
     
         4 . The synthetic turf field of  claim 1 , wherein said layer of particulate matter comprises resilient particles. 
     
     
         5 . The synthetic turf field of  claim 1 , wherein said layer of particulate matter comprises a mixture of hard particles and resilient particles. 
     
     
         6 . A synthetic turf field, comprising:
 a substrate;   a plurality of strips of synthetic turf disposed on said substrate, each of said plurality of strips including a plurality of synthetic strands tufted through a backing layer and extending a predetermined height above said backing layer;   a shock resistant layer coupled between said substrate and said backing layer; and   a layer of particulate matter infill interspersed between said plurality of synthetic strands and disposed on said backing layer, wherein the depth of said layer is between about 10% and about 50% of said predetermined height;   wherein said layer has increased density that is sufficient to support said plurality of synthetic strands.
