Description

{Artificial Grass System Having Triple Layer Structure}

The present invention relates to an artificial turf system having a triple structure, and more particularly, to an artificial turf system having a triple structure, which has a restoring force, an elastic force and a binding force, and is easy to manufacture and improved in permeability and drainage, .

Artificial turf is a substitute for natural grass by making synthetic fiber such as polyvinylidene chloride, polyethylene, polypropylene, nylon, etc. as a material and having grass shape. Although artificial turf was first developed and used in the United States in 1956, it has a lower impact absorption rate than natural turf, absorbs heat to raise the temperature of the athletic field, and is disadvantageous in that it is non-environmental. Compared to natural grass, which requires a lot of complicated work such as weeding and lawn cutting, it is much easier to maintain and economical because it does not cost much to manage.

As shown in FIG. 1, synthetic grass such as polyvinylidene chloride, polyethylene, polypropylene, and nylon is commonly used as a synthetic fiber by a tufting method or a weaving method using a polypropylene The artificial turf pile A11 is formed and is installed on the ground of the hard base layer.

In addition, sand, silk, and rubber chips are stacked in the order of the artificial turf files, or they are mixed and filled in order to maintain the shape stability of the artificial turf pile, thereby preventing the user from being injured and providing appropriate elasticity.

In addition, the rubber chip prevents the sand or silica sand from hardening when used for a long period of time, and allows the elasticity of the floor to be maintained even if the sand or sand is hardened. Such rubber chips are often recycled by crushing waste tires.

However, when the rubber chip recycled from the waste tire is repeatedly used, it is crushed into fine powder. Such rubber powder can be accumulated in the human body through the respiratory apparatus. In addition, the rubber chip contains heavy metals and organic compounds above the reference value, It is often reported that students at the school that they have installed appeal for headaches, atopic dermatitis, and the like.

In addition, since artificial turf of the existing artificial grass often causes instability (flatness, elasticity, drainage, scouring) of the floor of the playground due to occurrence of frequent occurrence of loss and oysters, the artificial turf is often lost, It has been pointed out that the problem of injuring a person who becomes a fracture and irregular bounding of a ball cause loss of purpose.

Urethane coat is a form that the athlete is reluctant because of the heavy metal appearance and the impact on the knee elbow.

It is a triple structure artificial turf system made only of friendly human and environment-friendly material which is different from the existing one. It maintains the existing elasticity and also solves the existing problems through the prevention of scour, sinking, Purely developed infrastructure for man-made artificial turf systems.
