6. The artificial grass manufacturer fiber according to claim 4, wherein the polyester comprises polyethylene terephthalate and/or polytrimethylene terephthalate.
7. The artificial grass fiber according to claim 4, wherein the polyamide comprises co-polyamide (6/66) and/or polyamide-6.
8. The artificial grass fiber according to claim 1 wherein the artificial grass fiber comprises a core and a cladding, with the core and the cladding being made of different materials, the material for the core comprising one or more of polyesters, polypropylene, ethyl vinyl acetate, saturated styrene thermoplastic elastomer, polyamides, polyethylene compounds and copolymers of ethylene and acrylate, or combinations thereof.
9. The artificial grass fiber according to claim 8, wherein the material for the cladding is comprised of polyurethane, cellulose, cellulose derivatives, chitosan, polyvinyl alcohol and derivatives thereof, or a combination thereof.
10. The artificial grass fiber according to claim 9, wherein the derivatives of cellulose comprise viscose, ethyl cellulose, cellulose acetate butyrate, cellulose acetate propionate, cellulose (di)acetate, cellulose (tri)acetate and combinations thereof.
11. The artificial grass fiber according to claim 1 wherein a d-tex value for the overall artificial grass fibre ranges between 4000 and 20,000 dtex.
12. The artificial grass fiber according to claim 1 wherein the artificial grass fiber has a cross-section which exhibits a narrowing near the thickening of the wedge shape on both sides.
13. A method for producing an artificial grass fiber comprising extruding a material in an extruder wherein the material exiting the extruder is stretched to a degree of 1:3-1:7 and wherein the artificial grass fiber has an elongated cross-section that remains substantially constant along its longitudinal axis, wherein said cross-section is wedge-shaped, said wedge shape having a length A and a width B, the ratio A:B being in the 2-12.5 range.
14. An artificial lawn comprising artificial grass fibers according to claim 1.
17. The artificial grass manufacturer fiber according to claim 2 wherein the fiber comprises a material comprised of polyesters, polypropylene, ethyl vinyl acetate, saturated styrene thermoplastic elastomer, polyamides, polyethylene compounds and copolymers of ethylene and acrylate, or combinations thereof.
