[0039] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.
[0040] The following English abbreviations have the following meanings:
[0041] PP: Polypropylene;
[0042] PE: Polyethylene.
[0043] The utility model discloses an artificial turf with high resilience, which is used to solve the technical problems that the existing artificial turf has poor resilience, cannot provide people with a more comfortable stepping feeling, and cannot reduce the impact force on joints during exercise, resulting in easy joint damage.
[0044] See also Figure 1 An embodiment of the utility model provides an artificial lawn with high resilience, comprising: a base fabric 3 and grass fibers;
[0045] At least one row of first grass lines 1 and at least one row of second grass lines 2 are woven on the base fabric 3, and the first grass lines 1 and the second grass lines 2 are arranged in alternate rows;
[0046] The first grass line 1 is composed of at least one monofilament 11 and at least one straight mesh wire 12;
[0047] The second grass line 2 is composed of at least one curved wire 21 and at least one curved mesh wire 22;
[0048] The grass height of the second grass line 2 is less than the grass height of the first grass line 1 .
[0049] It should be noted that the monofilament 11 is a monolithic structure, the straight mesh wire 12 is a mesh straight seedling structure, the curved mesh wire 22 and the curved wire 21 are a curled structure, the first grass line 1 is composed of at least one monofilament 11 and at least one straight mesh wire 12, and the second grass line 2 is composed of at least one curved wire 21 and at least one curved mesh wire 22. Since the first grass line 1 and the second grass line 2 are arranged in alternate rows, the grass height of the second grass line 2 is less than the grass height of the first grass line 1. Therefore, when people step on the lawn, the grass wires of the first grass line 1 will press on the grass wires of the second grass line 2, and the grass wires of the second grass line 2 will compress and support the grass wires of the first grass line 1 for buffering, thereby reducing the impact force on the joints when people exercise; when people's feet leave the lawn, the grass wires of the second grass line 2 rebound, so that the supported first grass line 1 quickly stands up, which improves the resilience of the lawn and ensures the stiffness of the lawn, and can provide a more comfortable stepping feeling.
[0050] As a further improvement, the grass height of the curved wire 21 is smaller than the grass height of the curved mesh wire 22 .
[0051] It should be noted that the grass height of the curved wire 21 is smaller than the grass height of the curved mesh wire 22. Therefore, the grass height of the second grass line 2 has two levels. The curved wire 21 is used to support the curved mesh wire 22 to play a role in buffering and rebounding. The curved mesh wire 22 is used to support the monofilament 11 and the straight mesh wire 12. It is divided into two height levels to support the higher monofilament 11 and straight mesh wire 12, which further improves the stiffness, resilience and wear resistance of the lawn.
[0052] As a further improvement, the grass height of the monofilament 11 and the straight mesh wire 12 is 25-45 mm;
[0053] The grass height of Qusi 21 is 14-24 mm;
[0054] The grass height of the curved mesh wire 22 is 15-25 mm.
[0055] As a further improvement, the first grass line is composed of 4-8 monofilaments and 1 straight mesh wire, the denier value of the monofilament is 1000-1800D, the denier value of the straight mesh wire is 5000D-10000D, and the film width of the straight mesh wire is 8-12 mm;
[0056] The second grass line is composed of 6-10 curved wires and 1 curved mesh wire. The denier value of the curved wire is 300-800D, the denier value of the curved mesh wire is 5000D-7500D, and the membrane width of the curved mesh wire is 8-12 mm.
[0057] As a further improvement, the row spacing between the first grass line and the adjacent second grass line is 3 / 16-3 / 8 inches;
[0058] The number of needles of the first grass thread and the second grass thread is the same, both 180-280 needles / m.
[0059] It should be noted that tufting density = number of rows × number of needles. When the row spacing between the first grass line 1 and the adjacent second grass line 2 is 3 / 16 inches, in 1m 2 There are 210 rows of grass threads on the base fabric 3, and the number of needles of the first grass thread 1 and the second grass thread 2 is the same, both 180 needles / m, and the tufting density is 37800 needles / m 2 .
[0060] As a further improvement, the curved yarn 21 is a one-step PP curved yarn.
[0061] It should be noted that the one-step PP curved wire has a lower shrinkage rate than PE curved wire, better elasticity, can play a more effective supporting role, has better overall stiffness and resilience, is relatively hard, and has a higher cost, making it a high-end product.
[0062] As a further improvement, the material of the monofilament 11, the straight mesh wire 12 and the curved mesh wire 22 is PE.
[0063] See also Figure 2 As a further improvement, the base fabric 3 includes an adhesive layer 31 and a barrier layer 32 stacked in sequence from bottom to top;
[0064] The adhesive layer 31 is coated with an adhesive;
[0065] The warp and weft density of the barrier layer 32 is greater than the warp and weft density of the adhesive layer 31 , and the barrier layer 32 is used to prevent the adhesive from seeping out of the top of the base fabric 3 .
[0066] It should be noted that when the grass yarns are woven and assembled on the base fabric 3, adhesive is applied mechanically on the bottom of the base fabric 3, and then dried and solidified, so that the grass yarns and the adhesive layer 31 are bonded into a whole. The warp and weft density of the barrier layer 32 is greater than the warp and weft density of the adhesive layer 31, so the adhesive cannot penetrate to the top of the base fabric 3 (i.e., the top of the barrier layer 32), thereby playing the role of fixing and protecting the grass yarns.
[0067] The adhesive is preferably styrene-butadiene latex.
[0068] See also Figure 2 As a further improvement, the adhesive layer 31 includes a mesh cloth 311 and a base cloth 312 stacked in sequence from bottom to top, and the warp and weft density of the mesh cloth 311 is less than the warp and weft density of the base cloth 312.
[0069] It should be noted that the adhesive layer 31 includes a mesh cloth 311 and a base cloth 312 stacked in sequence from bottom to top, and the warp and weft density of the mesh cloth 311 is smaller than that of the base cloth 312, so that the adhesive applied to the bottom of the base cloth 3 can penetrate from the mesh cloth 311 to contact the base cloth 312, and the grass fibers are fixed in two layers, thereby better fixing the grass fibers;
[0070] In addition, the mesh cloth 311 can facilitate positioning when installing the lawn.
[0071] As a further improvement, the warp density of the mesh cloth 311 is 31±5 strands / 10 cm, the weft density of the mesh cloth 311 is 25±5 strands / 10 cm, and the gram weight of the mesh cloth 311 is 50±10 g / m 2 ;
[0072] The warp density of the base fabric 312 is 110±5 strands / 10 cm, the weft density of the base fabric 312 is 45±5 strands / 10 cm, and the gram weight of the base fabric 312 is 97±10 g / m 2 ;
[0073] The warp density of the barrier layer 32 is 110±5 strands / 10 cm, the weft density of the barrier layer 32 is 63±5 strands / 10 cm, and the gram weight of the barrier layer 32 is 120±10 g / m 2 .
[0074] The technical solution of the present invention is further described in detail below in conjunction with specific embodiments and drawings. It should be understood that the following embodiments are only used to explain the present invention and are not used to limit the present invention.
