PROBLEM TO BE SOLVED: To provide an artificial lawn having stable durability without being fibrillated over a long period of time.SOLUTION: In the artificial lawn, flat filament yarns, which are produced by uniaxially stretching crystalline plastics to give a crystal orientation of 0.75-0.90, are used as a pile 3 to be implanted in a base fabric 2. In another embodiment, when H represents a minor-axis-direction length of a cross-section of the pile 3 and W represents a major-axis-direction length thereof, an oblateness (W/H) of the pile 3 is in the range of 3.0-7.0, and an elastic modulus in tension of the pile 3 is in the range of 150-350 N/mm2. |
