Abstract
An artificial turf of the invention is disclosed in which tufts of artificial grass filaments are implanted on a backing structure to form a pile surface, and tufts of assist filaments, which are shorter than the artificial grass filaments, are implanted between the tufts of the artificial grass filaments. This construction prevents the artificial grass filaments from folding for a long period of time since the assist filaments support the artificial grass filaments, so that a soft and resilient feel resembling natural turf can be obtained. When using longer lengths of artificial grass filaments, it is possible to obtain an appearance similar to natural turf and to enhance sliding characteristics on a turf surface, whereby sliding actions in a soccer game or the like can be performed readily. Furthermore, in the case of providing a sand layer over the backing cloth with the tips of the artificial grass filaments projected from the surface of the sand layer, the obtained artificial turf maintains a softness suitable for use in courts, playgrounds or the like for a long period of time.
