砂などの充填材を散布して、自然感を出せるようにして
いる。(Prior art and problems to be solved) Conventionally, as artificial grass, polypropylene, nylon, polyester, leaf members made of vinylidene chloride, etc. are planted with a tufting machine to project hair, and this is projected. BACKGROUND ART Artificial turf in which a backing coating layer such as rubber or vinyl chloride is bonded from the back side of a braided base fabric is known. In addition, when such artificial grass is used on a golf course,
A filler such as sand is sprayed to give a natural feeling.

など問題となっていた。However, in such a conventional artificial turf, the leaf member is made of a thermoplastic synthetic resin (flat yarn or the like) cut in a tape shape as it is or lightly twisted. Therefore, when the filler is sprayed, there is a problem that the filler cannot be sufficiently held by the leaf member. In addition, such a leaf member is inferior in durability such as repulsive force and abrasion resistance, and it is not possible to hold the leaf member almost upright by long-term use. There has been a problem that the number of parts is reduced due to cutting and wear.

れ、植毛される。FIG. 2 shows an enlarged cross-sectional view of the portion where the leaf member 2 is planted. As shown in FIGS. 3 and 4, the leaf member 2 before flocking is composed of a tape-shaped net member 8 (7000 to 30,000 denier) consisting of a linear portion 8a and an intersection portion 8b. The mesh member 8 is manufactured by extruding and stretching a thermoplastic synthetic resin, so that the intersections are fused. The method for manufacturing the mesh member itself is publicly known, and for example, it is already sold as a product under the trade name of Netron. And the mesh member 8
Before being applied to the tufting machine, the yarn is false twisted or squeezed through, for example, a voice used in the field of rope manufacturing to form a pile yarn having a small diameter as shown in FIG.

人工芝構造体の自然感が大きく改善される。In the above aspect, the leaf member 2 includes the linear portion 8a and the intersection portion 8b.
Since it is composed of the mesh member 8 composed of, the strength, wear resistance and repulsive force are greatly improved. Therefore,
The leaf member can be maintained in a substantially upright state for a long period of time, and the durability is improved by about 2 to 3 times as compared with the conventional one. Further, since the leaf member has a net-like structure, when it is filled with a filler such as sand, the leaf member itself is filled together with the gap between the leaf members, and the filler is retained therein for a long time. Note that, for example, when the mesh member is colored green, the hue is different between the linear portion and the intersection portion,
The natural feeling of the artificial grass structure is greatly improved.
