PARTICULATE SUBSTANCE FOR FILLING ARTIFICIAL TURF AND ARTIFICIAL TURF STRUCTURE FILLED WITH THE PARTICULATE SUBSTANCE FOR FILLING ARTIFICIAL TURF

摘要

A recycling technique for long-pile artificial turfs is provided in which a spent artificial turf is recycled and formed into an elastic particulate substance suitable for use as a filler for long-pile artificial turfs. The particulate substance (5), with which the space among the piles (4) of an artificial turf (3) is filled, is obtained by using as a raw material an artificial turf comprising at least 50 wt.% thermoplastic resin, adding an elastomer to the raw material, and forming the resultant mixture into particles. The particulate substance (5) has a specific gravity regulated to 1.10 or higher and is used for the filling.
