Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial turf structure suitable for laying on a walking path or a walking path of a golf course, a mat of a driving range, a park, a playground or the like.

[0002]

[Technical Technology] Conventionally, as artificial grass, for braided base cloth,
Fiber bundles such as polypropylene, flat yarns made of polyethylene, nylon, polyester, vinylidene chloride, etc. are flocked by a tufting machine, and this is projected,
An artificial turf is known in which an adhesive layer made of rubber, latex or the like and a reinforcing base fabric made of nylon or the like are sequentially bonded from the back side of a braided base fabric.

However, in such a conventional artificial turf, there are a large number of flock holes formed by flocking of fiber bundles, and therefore, abrasion resistance, durability such as tensile strength and tear strength are not sufficient. It was In particular, when it is used as a walking path on a golf course, it must be sufficiently resistant to the spikes of frequently-going golfers. Further, in recent years, electromagnetic induction type carts have been widely used in many golf courses, but it is possible that the artificial turf may be damaged early due to the violent movement of the wheels when the cart starts and stops. It was a problem. Therefore, there has been a strong demand for an artificial turf structure that is more durable than before.

In order to solve the above-mentioned problems that occur when a cart is used, the applicant of the present invention, in an artificial turf in which a plurality of fiber bundles are planted on a braided base cloth, has a durable reinforcement on the fiber bundle. We devised an artificial turf structure in which the road material was sewn in a pressed state, and filed a utility model registration application (Practical application Hei 1-1338).
No. 15). According to the above invention, the durability of the artificial turf is considerably improved, but when the reinforcing material is sewn to the braided base cloth in the above invention, it is pressed from above the fiber bundle, so that it is pressed. It has been found that it is not always easy to accurately sew a reinforcing material, for example, a durable reinforcing base cloth such as nylon cloth, at a predetermined position due to the repulsive action of the fiber bundle.

Further, the artificial turf structure of the above invention is considered only for durability when using a cart. Prior to the present invention, the artificial turf structure is used for a walking path of a golf course, a walking path, a golf course practice mat, etc. No attempt has been made to improve the durability of the artificial grass structure.
