Description

Artificial turf for football field {An artificial turf for football ground}

The present invention relates to an artificial turf for a soccer field having similar functionality to that of natural grass. More specifically, the present invention relates to an artificial turf for a soccer field having slip and pile stability such as natural grass.

Conventionally, artificial turf for soccer field is formed of polypropylene or polyamide fibers with a release pile made of polypropylene or polyamide fibers on a fiber bubble 1 of polypropylene having a length of 12 to 20 mm, and sand (cushion material) between the piles. ) Filled products have been widely used.

However, since the piles of the artificial turf for the conventional soccer field are made of polypropylene or polyamide fibers having a high coefficient of friction, slippage of the artificial turf is poor. As a result, a soccer player could not effectively perform techniques such as sliding and tackle, and there was a problem in which an injury of a player occurred frequently.

In addition, the conventional turf artificial turf has a problem in that the shape stability of the pile (pile) is bad because the length of the pile (pile) to maintain a similar level to 12 ~ 20mm. Specifically, when the artificial grass pile (pile) fell down, there was a problem that the elastic recovery lacked again. This made it difficult for players to demonstrate their skills such as tackle.

The present invention to solve the problems of the conventional artificial turf for the football field, to provide an artificial turf for the football field with good sliding and pile stability like the natural grass. Another object of the present invention is to provide an artificial turf for a football field that can allow a soccer player to fully exercise his skill and reduce the injury of a player to the level of natural turf during a game.

※ Explanation of Codes of Major Parts

1: Fiber bubble 2: Long pile 3: Shot pile

4: rubber chip 5: sand 6: ground

The artificial turf for the soccer field of the present invention for achieving the above problems is in the artificial turf for the soccer field consisting of the fiber bubble (1), the pile formed on the fiber bubble and the cushioning material filled between the pile, on the fiber bubble (1) Long piles (2) of flat yarns made of polyethylene or copolyethylene and short piles (3) of crimp yarns made of polyamide are formed alternately between the piles (2,3). It is characterized in that the cushion material composed of sand (5) or sand (5) and the rubber chip (4) is filled.

Hereinafter, the present invention will be described in detail.

First, the present invention is made of alternating long piles (2) of flat yarn made of polyethylene or copolyethylene and short piles (3) of crimp yarn made of polyamide on the fiber bubble (1). have.

As a method of forming the long pile (2) and the short pile (3) on the fiber bubble (1), a method of manufacturing the fiber bubble and the pile (2,3) at the same time by moket weaving may be used, A method of tufting the piles 2, 3 onto the fiber bubble 1 may be used.

It is preferable to use polypropylene fiber as a raw material of the fiber bubble 1. The yarn for the long pile 2, which is a flat yarn, is produced by a slitting or splitting method in which a resin sheet is produced and then longitudinally torn. Yarn for short pile (3) is produced by producing a circular yarn from polyamide, and then processing it by a known crimping process.

Since the long piles 2 are made of polyethylene or copolyethylene yarns having a low coefficient of friction, they have good sliding properties as natural grass. In addition, the long pile (2) is composed of a flat yarn so that players can feel the artificial turf during the soccer game.

The short files 3 are located between the long files 2 and serve to support the long files 2. In other words, the short file (3) serves to support the long file (2) to improve the shape stability to the external pressure of the long file (2). Since the short pile 3 of the present invention is made of a crimp yarn with good elasticity, it can perform the above role more effectively.

The length of the long pile 2 is 25-60 mm, and the length of the short pile 3 is 12-30 mm. The fineness of the piles 2, 3 is preferably in the range of 4000 to 8000 denier.

Next, the present invention is characterized in that the cushion material consisting of sand 5 or sand 5 and rubber chips 4 is filled between the piles 2 and 3. It is more preferable that the cushion material is filled at a level of 2/3 to 3/4 of the length of the long pile 2.

In addition, using the sand (5) and the rubber chip (4) together, rather than using the sand (5) alone as a cushioning material, more preferably at a level of about 1: 2 to improve the cushioning and sliding properties More preferred. The size of the sand 5 is 4 to 5, the diameter (π) of the rubber chip 4 is preferably 1.0 to 3.0mm.

As described above, the artificial turf for the soccer field of the present invention is composed of a fiber material having a low coefficient of friction and a flat yarn having a structure similar to that of natural turf. In addition, the present invention is formed by alternating short piles 3 of the crimp yarn having good elasticity between the long pile (2), the shape stability of the pile against external pressure is very excellent.

Therefore, the present invention allows athletes to easily exert skills such as tackle and sliding, and can reduce injuries to natural turf levels during the game.

The present invention has the slipperiness and pile stability like natural grass, so that football players can easily exert their skills such as tackle and minimize injuries during the game.
