Description

Technical Field

[0001] The utility model relates to the technical field of artificial turf, and more particularly to a filling-free artificial turf. Background Art

[0002] In recent years, with the improvement of people's living standards, the use of artificial turf has become more and more widespread. Artificial turf can be used in sports events, such as football fields, tennis courts, golf courses, etc., and can also be used in environmental and landscaping, such as airports, apartment greening, public buildings, commercial areas and entertainment venues.

[0003] In order to increase the elasticity of artificial turf and make it closer to a good natural lawn, the surface of the artificial turf needs to be filled with quartz sand and elastic rubber particles during the construction of traditional artificial sports turf. As people's awareness of environmental protection increases, the European Commission has approved the proposal to "ban the sale of microplastic fillers in artificial grass systems". Once the ban takes effect, rubber particles will not be allowed to be added to artificial turf. Therefore, the research and development of artificial turf without filling has become a hot research and development hotspot in these areas.

[0004] CN215405410U discloses an infill-free artificial turf, which adopts straight wire weight of 9000D-13000D, curly wire weight of 4000D-5500D, grass tuft row spacing of 0.5-1.2cm, grass tuft height of 20-40mm, grass tuft density of 18000-28000 tufts / square meter, and is made by tufting or weaving. When this kind of artificial turf is actually used, the curly wire weight is low, the elastic effect is poor, and the curly wire has poor support effect on the straight wire, so the straight wire is easy to fall, resulting in a slippery lawn surface and athletes are easy to fall. CN219195543U discloses a non-filling artificial turf, which is made of broad-leaf curled monofilament fibers (weight of 8000Dtex-9000Dtex, height of 12-25mm) and fine-leaf curled fibers (weight of 5000Dtex-5500Dtex, height of 5-12mm), with a row spacing of 0.7-1.0cm and a density of 18000-40000 tufts / square meter. Since all the curled fibers are used in this artificial turf, the turf blanket surface is too flat, and the ball rolling resistance is too small and the rolling distance is too large in actual use, which causes athletes to consume more energy and get tired prematurely when exercising on such a field.

[0005] Therefore, how to provide a real filling-free artificial turf is a problem that the technical personnel in this field need to solve urgently. Utility Model Content

[0006] The utility model aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent.

[0007] Therefore, an object of the present invention is to provide an artificial turf without filling.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A filling-free artificial turf comprises: a base fabric layer, an adhesive layer and a grass fiber layer, wherein the adhesive layer is located at the bottom of the base fabric layer, the grass fiber layer is tufted on the top of the base fabric layer, and the grass fiber layer comprises two curved artificial turf fibers and at least one straight artificial turf fiber.

[0010] Preferably, the weight of the straight artificial turf fibers is 5500-15000 DTEX; the weight of the curved artificial turf fibers is 5500-10000 DTEX; and the cluster spacing of each row of grass fibers in the grass fiber layer is less than 0.8 cm.

[0011] Preferably, the straight artificial turf fibers are mesh artificial turf fibers and / or monofilament artificial turf fibers; and the curved artificial turf fibers are mesh curved artificial turf fibers and / or monofilament curved artificial turf fibers.

[0012] Preferably, the two types of curved artificial turf fibers include first curved artificial turf fibers and second curved artificial turf fibers;

[0013] The height of the straight artificial turf fibers is 20-50 mm; wherein the first curved artificial turf fibers account for 1 / 3-2 / 3 of the height of the straight artificial turf fibers, and the second curved artificial turf fibers account for 1 / 2-4 / 5 of the height of the straight artificial turf fibers.

[0014] More preferably, the height of the straight artificial turf fibers is 28-40 mm.

[0015] Preferably, both the first curved artificial turf fibers and the second curved artificial turf fibers are monofilament curved artificial turf fibers, and the first curved artificial turf fibers have 6-16 strands, and the second curved artificial turf fibers have 4-8 strands.

[0016] Preferably, the first curved artificial turf fibers have the same or different heights as the straight artificial turf fibers after being straightened.

[0017] Preferably, the grass silk layer is tufted on the top of the base fabric layer by means of same-cluster mixed weaving or row mixed weaving.

[0018] Preferably, the grass fiber layer is tufted on top of the base fabric layer in the order of a row of straight artificial turf fibers, a first curved artificial turf fiber, a second curved artificial turf fiber, and a row of first curved artificial turf fibers by mixed weaving in rows;

[0019] or,

[0020] The grass fiber layer is tufted on the top of the base fabric layer in the order of a row of straight artificial turf fibers and a second curved artificial turf fiber, and a row of first curved artificial turf fibers through a row-by-row mixed weaving method.

[0021] Preferably, the straight artificial turf fibers, the first curved artificial turf fibers and the second curved artificial turf fibers are tufted on the top of the base fabric layer in a co-tufted mixed weaving manner;

[0022] or,

[0023] The grass fiber layer is tufted on the top of the base fabric layer in the order of a row of straight artificial turf fibers and a second curved artificial turf fiber, and a row of first curved artificial turf fibers and a second curved artificial turf fiber through a row-by-row mixed weaving method.

[0024] Preferably, the cross-sectional shape of the grass fiber layer includes any one of a diamond shape, a triangle shape, an olive shape, an S shape, a V shape, etc., or a combination of multiple shapes.

[0029] Preferably, the infill-free artificial turf further comprises a glass fiber cloth layer; the glass fiber cloth layer is connected to the bottom of the base cloth layer; and the adhesive layer is arranged at the bottom of the glass fiber cloth layer.

[0030] Due to the high density and weight of the lawn fiber layer, the low-weight base fabric layer cannot support the lawn fiber layer, resulting in low lawn backing strength and poor dimensional stability. The glass fiber cloth layer can well meet the backing strength and dimensional stability issues due to its extremely high strength and low shrinkage characteristics.

[0032] 1. The first curved artificial turf fiber layer of the non-filling artificial turf provided by the utility model is 1 / 3-2 / 3 of the height of the entire non-filling turf, which is very thick and provides sufficient elasticity for the non-filling artificial turf, and can replace the use of traditional buffer elastic pads. In addition, a variety of curved artificial turf fibers are intertwined to support the straight artificial turf together, ensuring that the straight artificial turf fibers will not fall over during use. The straight artificial turf fibers and the second curved artificial turf fibers can cooperate to adjust the resistance required for the rolling of the ball, ensuring that athletes will not consume excess energy when exercising on the field and avoid fatigue;

[0033] 2. The non-filling artificial turf provided by the utility model adopts a high-weight base fabric and includes a glass fiber layer with greater strength and extremely low heat shrinkage performance, which ensures the dimensional stability of the non-filling artificial turf during use and will not cause quality problems such as bulging and shrinkage;

[0034] 3. The filling-free artificial turf provided by the utility model adopts a high-weight artificial turf fiber surface layer, which does not need to be filled with quartz sand and rubber particles at all, and has the advantages of easy production and convenient paving.
