Title:
ARTIFICIAL TURF
Document Type and Number:
WIPO Patent Application WO/1995/009949
Kind Code:
A1
Abstract:
An artificial turf according to the invention is constructed such that tufts of turf-shaped filaments are planted in a ground structure in a manner to form piles and tufts of subsidiary filaments which are shorter than the turf-shaped filaments are planted between the tufts of turf-shaped filaments. With such arrangement, the turf-shaped filaments are supported by the subsidiary filaments to be prevented from being laid flat over a long period of time, thus providing a good elasticity and a soft feeling of touch similar to natural turf. In addition, when long turf-shaped filaments are used, the artificial turf provides an appearance close to that of natural turf, and a sliding performance is improved on the surface of the artificial turf to facilitate play involving sliding in a game such as soccer and the like. In addition, in the case where a sand layer is provided on a base cloth with tip ends of the turf-shaped piles projecting above the surface of the sand layer, the elasticity of the subsidiary piles prevents the sand layer from being packed when trod, so that the artificial turf can preserve softness which is desired for a court or playground in a long-time use.
