The present invention relates to a triple structure and quadratic artificial turf for a soccer field, and more specifically, the bottom surface of the fiber foam contacting the ground drainage layer is coated with latex or polyurethane, and the polypropylene or polyethylene material is coated on the fiber foam. Single compressed monofilament fiber made of plywood with non fibrillation properties and pile B file with fibrillation properties made of polyethylene Piles are tufted alternately at regular intervals, and either one of the outer grass A file and the outer grass B file or the outer grass A file and the outer grass B file are monofilaments made of polypropylene or polyethylene. Grass pile piles are tufted together, and silica sand is filled between the grass piles on the fiber cloth. The upper part of the silica sand is angled to 3 relates to a medium-section and medium-4 crude synthetic turf for football fields, it characterized in that the chip is filled with the EPDM or SBR chip.

Conventionally, artificial turf for soccer field is made of polyethylene fiber and weaved grass pile with 50-55mm length (height) with fine fiberization (fibrillation, fibrillation) characteristics, and grass pile with single structure It is composed of grass only) or double structure (consisting of grass and inner grass), and then SBR (Styrene Butadiene Rubber) is installed between grass piles.However, the conventional artificial grass has only one branched fiber made of polyethylene. By using it as a grass, 2-3 years after construction, the grass pile is fibrillation, that is, it breaks down like a thread, which not only reduces the resilience of the grass pile significantly, but also causes the grass pile to be easily worn or broken. I had a problem. In addition, the fiber of single structure is about 15.88mm between the pile of the grass pile, which is wider than the double structure, so the fiber needs to be cut more thinly to cover the large space. Due to the shortened life.

The present invention uses only a fiber having a splitting property (fine fiberization, fibrillation) in order to overcome the problems of conventional monostructure or dual structure artificial turf which is poor in durability and playability, such as wear resistance and restoring force, Combining fibers with different characteristics and shapes into a triple or quadruple structure (combining outer grass A file, outer grass B file and inner grass file) to play comfortably and safely as well as natural grass It is to provide a triple structure and quadratic artificial turf for the football field with similar playability, resilience, and durability.

The present invention relates to a triple structure and quadratic artificial turf for a soccer field, and more specifically, to a artificial turf for a soccer field, which is composed of a fiber material, a grass fiber pile formed on the fiber foam paper, and a filler filled between the grass fiber piles. In this case, the bottom surface of the fiber base paper 3 in contact with the ground drainage layer 1 is coated with latex or polyurethane (2), and on the fiber base paper 3 as a single compressed monofilament fiber made of polypropylene or polyethylene material. The outer grass A pile 7 having non-fibrillation characteristics and the outer grass B pile 8 having fibrillation characteristics made of polyethylene are alternately tufted at intervals of 7.94-9.53 mm. The outer grass A file 7 and the outer grass B file 8 or the outer grass A file 7 and the outer grass B file 8 may be formed of polypropylene or polyethylene. Soil grass pile 6, which is a nofilament fiber, is tufted together, and between the grass piles on the fiber base paper 3, silica sand 4 having a particle diameter of 0.3-1.0 mm is filled and filled silica sand It relates to a three- and four-structure artificial turf for the football field, characterized in that the upper portion is filled with EPDM chip or SBR chip 5 of 0.6-2.5 mm in diameter.

Referring to the configuration of the present invention in detail with reference to Figures 1 to 3 as follows.

The ground drainage layer (1) of the tri- and quadruple artificial grass of the present invention is a commonly used method such as pitcher cone, ascone, asconcrete, aggregate aggregate finishing, and the slope of the ground drainage layer (sub base) is required by FIFA. It should be 0.6-1.0% gradient free of water and 80% of rainwater should be natural drainage and 20% permeability when artificial turf is constructed. Fibrous base paper (3) in contact with the ground drainage layer (1) is made of polypropylene (PP), it uses a double or triple reinforced, the lower surface is a latex coating or polyurethane coating (2) to the fiber base paper ( Let 3) receive strength. After coating, the holes are punched out at intervals of 9 cm x 5 cm to form 20% water permeability. The silica sand (4) to be used as a filler should contain more than 85% of silicon dioxide (SiO ₂ ), and use a diameter of 0.3-1.0㎜ and round silica sand to prevent injury of athletes during the game. The upper part of the silica sand is filled with an elastic chip (rubber chip), specifically, an SBR chip or an EPDM chip. In case of filling EPDM (Ethylene Propylene Diene Monomer) chip on top of silica sand, EPDM chip used should have more than 25% of EPDM content. On the other hand, the particle size of the SBR chip or EPDM chip used as a filler should be 0.6-2.5㎜, and use green, gray, and other colors that absorb less heat so as to lower the temperature in the football field. (Rubber chip) is used. In terms of gameability, EPDM chips have more elasticity than SBR chips, resulting in better ball rolling, bounds, shock absorption, friction, recovery, and elasticity, as well as outer grass A file (7), grass B file (8), and grass file. (6) Settled in a short time, and helps a lot in game performance. In addition, EPDM has no problem that the ball does not get dirty when there is no dust, and there is no phenomenon that the filler does not move when bound, and it is relatively heavier than SBR, so there is no phenomenon of floating in rainy weather. The filler is not biased. On the other hand, the height 10 of the filled silica sand layer is about 16 mm, and the height 11 of the EPDM chip or SBR chip layer is about 32 mm.

The fiber of the grass pile (6) is used in the triple structure and quadruple structure of the grass pile, polyolefin (PO) material such as polypropylene (PP) or polyethylene (PE) is used. The fiber is a monofilament type that is tough like a fishing line and performs heat treatment to have an irregular twisted shape (for example, irregular spring or spiral shape) to hold the movement of the filled elastic chip (rubber chip). Do it. The fibers of the inner grass pile 6 are tufted and woven into 8 strands so that the 16 strands of the inner grass 6 twisted into irregular shapes play a role as the inner grass in natural grass.

The outer grass A pile 7 is a single compressed monofilament fiber made of polyethylene (PE) or polypropylene (PP) material and has a characteristic of non-longitudinal splitting (non fibrillation). The use of fibers having non-fibrillation properties as the material of the outer grass A pile 7 compensates for the shortcomings of the conventional artificial turf that splits finely with long-term use, and improves the turf resilience and abrasion resistance. And to improve the playability.

Turfgrass B pile 8 having cracking properties (fibrillation) and turfgrass A pile 7 having non-cracking characteristics (non-fibrillation) are alternately tufted at intervals of 7.94-9.53 mm. In the case of the three-layer artificial turf, weaving the outer grass A pile (7) or the outer grass B pile (8) and the inner grass pile (6) together, and in the case of the four-layer artificial turf The inner grass file 6 is tufted together and woven into the outer grass A file 7 and the outer grass B file 8, respectively. That is, when constructing a three-layer artificial turf, the inner grass file 6 is woven together with the outer grass file of either the outer grass A file 7 or the outer grass B file 8, and the outer grass A file The spacing 9 between (7) and the outer grass B pile (8) is 7.94-9.53 mm tufted. In the case of the artificial turf having a quadruple structure, the inner grass file 6 is woven together with each of the outer grass files (surface A and outer grass B), and the outer grass A file 7 and the outer grass B file 8 The spacing of 9) is tufted to 7.94-9.53 mm.

Before tufting the inner grass pile 6 together with the outer grass pile on the fiber base paper 3, the inner grass pile 6 is heat-treated in advance to have an irregular spring shape or a spiral shape. The length (height) of the outer grass A pile (7), the outer grass pile (8) and the inner grass pile (6) is 55-65 mm, of which the inner grass pile (6) has a length of 55-65 mm. By heat-treating the fibers having the (height) to give a wave to be dried in an irregular spring form or spiral shape, the grass file (6) has a irregularly dried form as shown in the drawing as the height It should be less than 50mm. That is, when the artificial turf pile 6 is formed to have a height of 50 mm or less due to curling in an irregular shape, the maximum height is 55-65 mm. Soil grass pile (6) having an irregularly dried shape as described above prevents the movement of the elastic chip (rubber chip) filled between the grass piles, adjusts the bounds of the ball evenly, and the elastic chip (rubber) when rolling the ball It prevents the movement of chips so that you can play soccer with the feeling of natural grass.

The height 13 of the outer grass B pile is about 55-65 mm, and the length 12 of the upper end of the artificial turf is about 12 mm after fibrillation.

In the present invention, weaving a grass pile into three or four structures by weaving a combination or blend of fibers having three different characteristics and shapes (Outer Grass A Pile, Outer Grass B Pile, Inner Grass Pile) is conventional artificial turf. Complementing the disadvantages of inferior durability by using only the fibers having a splitting property in the game, not only can play comfortably and safely, but also triple and quadruple structures for soccer fields that have similar playability, resilience, and durability to natural grass. To provide artificial turf.

The present invention is not only able to play safely by weaving artificial turf into a triple structure or quadruple structure using three kinds of fibers with different characteristics, but also provides playability similar to that of natural grass. It has an excellent effect of providing artificial turf for soccer field with improved resilience and durability. In addition, the filling material is filled with a color EPDM chip or SBR chip having a variety of colors, it is also possible to provide a soccer field of the best conditions to play more comfortable and safe football.
