Abstract
Disclosed is an artificial turf fiber comprising: 1.0 to 10.0 wt % of the fiber a modifier polymer material, the remainder of the fiber including a base polymer material and at least one additive, wherein the modifier polymer material is polyethylene selected from an ultra-low density polyethylene (ULDPE) or a low density polyethylene (LDPE) or a combination thereof, wherein the base polymer material is polyamide, or polyester, or a combination thereof, and wherein the at least one additive includes a compatibilizer.
Claims18
An artificial turf fiber comprising:
- a modifier polymer material in an amount of 1.0 to 10.0% by weight of the fiber,
- the remainder of the fiber including a base polymer material and at least one additive, wherein the modifier polymer material is polyethylene selected from an ultra-low density polyethylene (ULDPE) or a low density polyethylene (LDPE) or a combination thereof,
- wherein the base polymer material is polyamide, or polyester, or a combination thereof, and
- wherein the at least one additive includes a compatibilizer.
An artificial turf comprising an artificial turf backing, and an artificial turf fiber according to any of the previous claims incorporated into the artificial turf backing.
A method of manufacturing an artificial turf fiber, the method comprising the steps of:
- creating a polymer mixture, the polymer mixture comprising 1.0 to 10.0 % by its weight a modifier polymer material, the remainder of the polymer mixture including a base polymer material and at least one additive, wherein the modifier polymer material is polyethylene selected from an ultra-low density polyethylene (ULDPE) or a low density polyethylene (LDPE) or a combination thereof, wherein the base polymer material is polyamide, or polyester, or a blend of the polyamide and the polyester, wherein the at least one additive includes a compatibilizer, wherein the polymer mixture comprises domains of the modifier polymer material;
- extruding the polymer mixture into a monofilament;
- quenching the monofilament;
- reheating the monofilament;
- and
- stretching the reheated monofilament to reshape the domains of the modifier polymer into threadlike structures and to form the monofilament into an artificial turf fiber;
