Abstract
An artificial turf that includes a first face yarn, a second face yarn, and a stitch-in yarn. The second face yarn is textured in some embodiments, for at least the reason of creating a zone such as a textured zone. A knot is formed by knitting the first face yarn, the second face yarn, and the stitch-in yarn together. A row of knots is also formed in this manner. A backing is formed when a lay-in yarn is extended between at least two rows of the knots and knitted to hold the at least two rows of knots together. A coating is coupled to the backing to prevent, among other things, detachment of the yarns after extended use of the artificial turf. An underlayment is positioned beneath the backing such that a stable base is provided for the artificial turf.
Claims29
An artificial turf comprising:
- a first face yarn and a second face yarn, the second face yarn being textured;
- a backing that is formed by knitting the first face yarn, the second face yarn, a stitch-in yarn, and a lay-in yarn such that the first face yarn appears to be longer than the second face yarn;
- a coating coupled to the backing to prevent, among other things, detachment of the yarns after extended use of the artificial turf;
- and
- an underlayment positioned beneath the backing such that a stable base is provided for the artificial turf.
An artificial turf comprising:
- a first face yarn, a second face yarn, and a stitch-in yarn, the second face yarn being textured;
- a knot that is formed by knitting the first face yarn, the second face yarn, and the stitch-in yarn together, wherein a row of knots is formed;
- a backing that is formed when a lay-in yarn is extended between at least two rows of the knots and knitted to hold the at least two rows of knots together;
- a coating adhered to the backing to enhance longevity of the knot;
- and
- an underlay positioned beneath the backing such that a stable base is provided for the artificial turf.
A method for creating an artificial turf comprising:
- extruding a pellet through a spinneret to form an extended ribbon;
- knitting the extended ribbon into a blend of other ribbon, that has been textured, and stitch-in yarn to form knots;
- cutting the extended ribbon to create a flat face yarn that has a length of approximately one inch;
- forming rows of knots from the extended ribbon, the other ribbon, and the stitch-in yarn;
- and
- knitting a lay-in yarn into the rows of knots to combine the rows of knots and create a backing for the artificial turf while the combination also creates a textured zone on top of the backing and the flat face yarn extends upwardly from the textured zone.
An artificial turf comprising:
- a first face yarn and a second face yarn;
- a backing that is formed by knitting the first face yarn, the second face yarn, a stitch-in yarn, and a lay-in yarn such that the first face yarn appears to be longer than the second face yarn;
- a coating coupled to the backing to prevent, among other things, detachment of the yarns after extended use of the artificial turf;
- and
- an underlayment positioned beneath the backing such that a stable base is provided for the artificial turf.
