Artificial turf with opaque face yarn and translucent thatch yarn fibers

Abstract

An artificial turf includes translucent thatch yarn fibers and opaque face yarn fibers that are integrated in a carrier.

1 . An artificial turf comprising:
 a carrier;   translucent thatch yarn fibers integrated in the carrier; and   opaque face yarn fibers integrated in the carrier.   
     
     
         2 . The artificial turf of  claim 1 , wherein the length of the thatch yarn fibers is smaller than the length of the face yarn fibers. 
     
     
         3 . The artificial turf of  claim 1 , wherein the translucent thatch yarn fibers are transparent. 
     
     
         4 . The artificial turf of  claim 1 , wherein the artificial turf comprises two or more subregions, wherein all face yarn fibers contained in a subregion have the same color, which is different from the color of the face yarn fibers contained in all subregions adjacent to that subregion. 
     
     
         5 . The artificial turf of  claim 1 , wherein the two or more subregions form a color pattern being selected from a group including:
 a logo of an organization;   field markings and regions defined by the field markings;   symbols of a game; and   a pattern representing a text or an image.   
     
     
         6 . The artificial turf of  claim 1 , wherein the face yarn fibers includes one or more pigments. 
     
     
         7 . The artificial turf of  claim 1 , wherein the thatch yarn fibers are free of pigments. 
     
     
         8 . The artificial turf of  claim 1 , wherein the thatch yarn fibers and/or the face yarn fibers are selected from a group comprising including polyethylene fibers, polyamide fibers, and polypropylene fibers. 
     
     
         9 . The artificial turf of  claim 1 , wherein the thatch yarn fibers and/or the face yarn fibers are texturized. 
     
     
         10 . The artificial turf of  claim 1 , wherein the thatch yarn fibers include a nucleating agent and the face yarn fibers are free of the nucleating agent or include a smaller amount of the nucleating agent than the thatch yarn fibers. 
     
     
         11 . The artificial turf of  claim 10 , wherein the nucleating agent is an organic acid, an organic acid ester or organic acid salt. 
     
     
         12 . The artificial turf of  claim 10 , wherein the nucleating agent is a salt of hexahydrophthalic acid, sorbic acid or salicylic acid, in particular a calcium salt of hexahydrophthalic acid. 
     
     
         13 . A layered surface structure comprising:
 a display layer; and   an artificial turf including translucent fibers, the artificial turf being placed on top of the display layer; wherein the display layer includes one or more display elements adapted to emit light signals toward the artificial turf.   
     
     
         14 . The layered surface structure of  claim 13 , the artificial turf being an artificial turf including:
 a carrier;   translucent thatch yarn fibers integrated in the carrier; and   opaque face yarn fibers integrated in the carrier.   
     
     
         15 . A method of manufacturing an artificial turf comprising:
 providing a carrier;   integrating translucent thatch yarn fibers in the carrier; and   integrating opaque face yarn fibers in the carrier.   
     
     
         16 . A method of manufacturing a layered surface structure comprising:
 providing a display layer including one or more display elements;   placing an artificial turf including translucent fibers on top of the display layer;   wherein the display elements are adapted to emit light signals toward the artificial turf.
