Description

  The present invention relates to the field of artificial turf, and more particularly to artificial turf combining artificial turf and natural turf.

  Artificial lawns are widely used in fields such as stadiums, leisure facilities, and decorations because of their advantages such as environmental friendliness, durability, ease of management, quick drainage, and low water consumption. On the other hand, the conventional artificial turf fixed the turf on the base fabric to the foundation layer with styrene butadiene latex or a PU-based adhesive, so the water permeability of the turf is not ideal and the drainage hole is provided , It can not be discharged immediately when a large amount of rainwater is accumulated. In addition, since the styrene butadiene latex or PU adhesive can not be reused by plasticization, the conventional artificial lawn can not be recovered and reused even after the predetermined useful life has expired, which results in wasting resources. Problems are inevitable. Currently, natural turf may be laid in a part of stadiums such as soccer and golf. In order to manage natural lawns, problems such as consumption of water resources, contamination with pesticides and fertilizers, hardening of the soil, weeding, waste removal, and mowing are not only inevitable, so management costs increase. Environmental pollution is also happening.

Applicants have investigated the prior art and have found that there is an artificial turf that combines artificial turf and natural turf, taking advantage of the advantages of natural turf and artificial turf.
For example, Patent Document 1 discloses "artificial turf in which artificial turf and natural turf are combined, and a method for producing the same." The artificial turf that combines the artificial turf and the natural turf includes an original soil layer and an improved layer disposed above the original soil layer, sowing seeds in the improved layer and planting the natural turf, and using a planting machine An artificial turf is planted between the natural turf and the bottom soil layer is compacted to form a raw soil layer. Next, a base layer consisting of 70% sand, 20% peat, and 10% porous ceramic balls is uniformly spread on the base soil layer to form an improved layer, and further, grass is applied to the improved layer at a predetermined density. The planting plant is used to sow the artificial turf, the planting machine is used to plant the artificial turf on the improved layer, or in the improved layer, the planting machine is used to plant the artificial turf, and the grass seed is manufactured so as to sow uniformly. In the patent, since the artificial turf is planted on the improved layer using a planting machine, the bottom of the artificial turf yarn can not be fixed firmly.

  Patent Document 2 discloses "artificial lawn and its manufacturing process". The artificial turf includes a soil base layer, a warp knitted mesh laid on the upper side of the soil base layer, and a fiber grass bundle woven into the warp knitted mesh, and the warp knitted mesh has a lattice structure woven with warp yarns and weft yarns. The natural turf is planted on the lattice formed in the warp-knitted mesh, the root part of the natural turf is planted in the soil base layer, and the warp and weft are both turf yarn bundles knitted by twisting fiber turf There is a bunch of turf yarn shaped like a fried candy called hemp flower in China. The root portion of the fiber grass bundle is woven into a bundle of turf yarn, the fiber grass bundle is formed by connecting at least two fiber turf threads, and the root portion of the fiber grass bundle is G-shaped , And uniformly woven into tufts of tufts, the stems of the tufts of fiber tufts are all located on the same side of the tufts of tufts, and the roots of the tufts of fiber tufts are one of the joints between the tufts of fibrous turf Inserted from the side and pulled out from the other side of the seam. In this patent, natural grass is inserted or planted in a lattice of a warp knitted mesh, and the root of the natural grass is below the warp knitted mesh so that it can not be effectively combined with the warp knitted mesh and the robustness is inferior. ing. In addition, since it is necessary to insert or plant natural turf into the lattice of the warp knit mesh, the manufacturing process is complicated. Furthermore, because of the complexity of the woven structure of the warp knitted mesh, it was difficult to fix the artificial turf yarn.

Chinese Patent No. 105993275 (Chinese Patent Application No. 201610498763.2) Chinese Patent No. 104264565 (Chinese Patent Application No. 201410564507.X)

  The present invention was made for the purpose of solving the drawbacks of the prior art, and combined artificial turf with natural turf to not only fix natural turf effectively but also to improve the robustness of the bottom of the entire turf Provide artificial grass.

The present invention made to achieve the above purpose is
An artificial turf that is a combination of artificial turf and natural turf, which is interwoven into a soil base layer, a lattice-like base layer laid on top of the soil base layer, and woven with warp yarns and wefts, and a lattice base layer The weft is arranged in an S-like shape, and the warp reciprocates up and down in the S-shaped arc of the weft to form a figure-like fixing knot, an artificial The turf yarn passes through the inside of the 8-shaped knot and is fixed between the warp and weft by being tightened by the warp.

  Furthermore, in the artificial grass combining artificial grass and natural grass according to the present invention, a soil layer for planting natural grass is spread on a lattice-like underlayer, and the height of the soil layer for planting natural grass is artificial The natural turf is planted in the soil layer for planting of natural turf, which is lower than the height of turf yarn, and the root part of the natural turf is entangled in a lattice-like underlayer.

  In the artificial grass combining artificial grass and natural grass according to the present invention, the height of the soil layer for planting natural grass is 30 to 80% of the height of the artificial grass yarn.

  In the artificial lawn in which the artificial turf according to the present invention and the natural turf are combined, the shape of the lattice in the lattice-like base layer is one or more selected from rice-like, rhombus, triangle and circle.

  The artificial grass combining artificial grass and natural grass according to the present invention has the following beneficial effects. In the artificial lawn according to the present invention, since the soil layer for planting natural grass is spread on the lattice-like foundation layer, natural grass can be easily planted in the soil layer for natural grass planting. When natural turf grows, its root entangles with a lattice-like base layer to not only fix natural turf effectively but also to improve the robustness of the bottom of the entire turf. In the artificial lawn according to the present invention, since the artificial turf yarn is woven into the lattice-like underlayer and firmly bonded, high tensile force can be obtained without using styrene butadiene latex, and it is woven Because there are many holes at the bottom of the foundation layer, the lawn has excellent water permeability and is hard to collect water. If the lattice-like basement hole is provided in a predetermined range, it can be used as a pet glass, animal excrement can be discharged directly from the hole, bacteria can not grow easily, and it is easy to clean. In addition, since it is only necessary to weave in artificial turf yarn, and it is not necessary to use styrene butadiene latex, it is also possible to recover and reuse the entire turf.

It is a figure showing roughly the structure of the artificial lawn concerning the present invention. It is a figure showing roughly the weaving structure by the warp, weft, and artificial turf in the lattice-like ground layer concerning the present invention.
