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.
Claims20
A method of making an artificial turf, comprising:
- delivering at least first, second, and third distinct yarn bundles from a creel assembly to each needle of a plurality of needles, wherein each one of the first, second, and third yarn bundles varies from the other yarn bundles of the first, second, and third yarn bundles of the tuft in at least one of material, color, texture, tuft denier, denier per filament, and cross-section
- using the plurality of needles to tuft a plurality of rows of individual tufts into a backing layer, wherein each tuft comprises at least first, second, and third distinct yarn bundles per tuft, wherein each one of the first, second, and third yarn bundles varies from the other yarn bundles of the first, second, and third yarns of the tuft in at least one of material, color, texture, tuft denier, denier per filament, and cross-section,
- wherein the first, second, and third yarn bundles of each tuft are not twisted together prior to tufting, and wherein the at least first, second, and third yarn bundles of each tuft are simultaneously delivered through the backing layer to produce the tuft.
The method of claim 15, wherein the bulk continuous filament yarn, the 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.
