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.
Claims19
A method of making an artificial turf, comprising:
- delivering at least 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 a plurality of rows of individual tufts into a backing layer, wherein each tuft comprises at least the 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, second, and third yarns of each tuft are not twisted together prior to threading through the eye of each needle of the plurality of needles, and wherein the at least 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,
- 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.
