Abstract

Provided are artificial turf with which a temperature alleviation effect can be sustained over an extended period and which is easily maintained, and an artificial turf facility wherein the artificial turf is laid. A first pile ( 41 ), and a second pile ( 42 ) which comprises a water absorbent void therein which absorbs water, which configure the artificial turf, are placed mixed among each other in a base fabric ( 31 ) at a prescribed proportion.

First claim

The invention claimed is:

1. Artificial turf comprising a primary backing and piles implanted in the primary backing, the piles comprising at least a first pile and a second pile, wherein the first pile is made of polypropylene or polyethylene, and the second pile is made of fibers of an acrylic hydrophilic resin having hydrophilized voids in the inner part thereof, said voids including extremely fine open-cells formed to be thin and elongated along the fiber elongation direction with said open-cells having an average pore size of 10 nm; the first and second piles being implanted as a mixture in the primary backing with the second pile implanted so as to satisfy the relationship: B/(A+B)=10 to 30% by volume, wherein A represents the implanted amount of the first pile and B represents the implanted amount of the second pile.

2. The artificial turf according to claim 1 , wherein the space between the piles is further filled with a filler.

3. The artificial turf according to claim 1 , wherein the primary backing has a mass of 100 to 200 g/m 2 and comprises a plain weave cloth made of a synthetic resin of polypropylene or polyethylene.
