Artificial Turf And Associated Devices And Methods For Making Same

Abstract

Implementations herein describe an artificial turf having a backing layer and a plurality of rows of individual tufts tufted into the backing layer. Each tuft comprises at least three yarns per tuft and each one of the at least three yarns varies in at least one of material, color, texture, denier and cross-section. Each row of individual tufts is substantially similar to each adjacent tufted row and adjacent tufts on a given row are spaced apart at a predetermined gauge.

We claim: 
     
         1 . An artificial turf article comprising:
 a backing layer; and   a plurality of rows of individual tufts extending through the backing layer, wherein each tuft comprises at least first, second, and third distinct yarns per tuft, wherein each one of the first, second, and third yarns varies from the other yarns of the first, second, and third yarns of the tuft in at least one of material, color, texture, denier, denier per filament, or cross-section,   wherein the first yarn is a texturized yarn, wherein the second yarn is a slit tape yarn, and wherein the third yarn is a monofilament yarn.   
     
     
         2 . The artificial turf article of  claim 1 , where the plurality of rows of individual tufts comprise a plurality of cut tufts. 
     
     
         3 . The artificial turf article of  claim 1 , wherein the at least first, second, and third distinct yarns per tuft further comprises a wrap yarn. 
     
     
         4 . The artificial turf article of  claim 1 , further comprising an infill material dispersed in between the tufts of the plurality of rows of individual tufts, wherein the second yarn folds over at a face surface of the artificial turf article, wherein the second yarn is configured to reduce splash of the infill material when the face surface of the artificial turf article is impacted, and wherein the first yarn is configured to trap infill and reduce infill migration. 
     
     
         5 . The artificial turf article of  claim 4 , wherein the infill material comprises at least one of rubber particles, sand, or natural materials. 
     
     
         6 . The artificial turf article of  claim 1 , wherein at least one of the first, second, and third yarns of each tuft comprises a material selected from the group consisting of LDPE, MDPE, Nylon, PP, PET, PLA, and co-extruded biomaterials thereof. 
     
     
         7 . The artificial turf article of  claim 1 , wherein the texturized yarn, the slit tape yarn, and the monofilament yarn each comprise a respective material selected from the group consisting of LDPE, MDPE, Nylon, PP, PET, PLA, and co-extruded biomaterials thereof. 
     
     
         8 . The artificial turf article of  claim 7 , wherein the texturized yarn comprises polyethylene. 
     
     
         9 . The artificial turf article of  claim 7 , wherein the tape yarn comprises polyethylene. 
     
     
         10 . The artificial turf article of  claim 8 , wherein the tape yarn comprises polyethylene. 
     
     
         11 . The artificial turf article of  claim 7 , wherein the monofilament yarn is selected from the group consisting of nylon, polyethylene, and polypropylene. 
     
     
         12 . The artificial turf article of  claim 11 , wherein the monofilament yarn comprises nylon. 
     
     
         13 . The artificial turf article of  claim 11 , wherein the monofilament yarn comprises polyethylene. 
     
     
         14 . The artificial turf article of  claim 11 , wherein the monofilament yarn comprises polypropylene. 
     
     
         15 . The artificial turf article of  claim 10 , wherein the monofilament yarn is selected from the group consisting of nylon, polyethylene, and polypropylene. 
     
     
         16 . The artificial turf article of  claim 15 , wherein the monofilament yarn comprises nylon. 
     
     
         17 . The artificial turf article of  claim 15 , wherein the monofilament yarn comprises polyethylene. 
     
     
         18 . The artificial turf article of  claim 15 , wherein the monofilament yarn comprises polypropylene. 
     
     
         19 . The artificial turf article of  claim 1 , wherein the first, second, and third distinct yarns have respective deniers ranging from 100 to 7,500, wherein the first, second, and third distinct yarns have a combined denier of 10,800 to 16,600, and wherein the combined denier is equal to a total of the respective deniers of the first, second, and third distinct yarns. 
     
     
         20 . A method of making the artificial turf article of  claim 1 , comprising:
 delivering at least the first, second, and third distinct yarns from a creel assembly to each respective needle of a plurality of needles;   threading the first, second, and third distinct yarns through an eye of each respective needle of the plurality of needles; and   using the plurality of needles to tuft the plurality of rows of individual tufts into the backing layer,   wherein the first, second, and third yarns of each tuft are simultaneously delivered, by a single needle of the plurality of needles, through the backing layer to produce the tuft.
