Description

Technical Field

[0001] This utility model relates to the field of turf technology, specifically to an artificial turf and turf system for competitive sports. Background Technology

[0002] Artificial turf is widely used in various places such as sports fields, fitness centers, school playgrounds, landscaping, and home decoration due to its exquisite and uniform appearance, excellent performance, long service life, low maintenance costs, and immunity to weather conditions. With the development of artificial turf, the requirements for its appearance and performance are becoming increasingly stringent. Because of its industrialized production model, the artificial turf fibers are relatively uniform; existing turf clumps all have a linear, straight fiber structure, and the height and uprightness of the fibers tend to be consistent. After being transported in tightly compressed packaging such as rolls or blocks, the fibers typically bend and tilt in one direction.

[0003] During on-site installation, insufficient thickness of the infill material, loss of infill material during sports activities and extreme rain or snow, and untimely or substandard replenishment of the infill material can lead to the grass fibers lying flat in the same direction. This can cause obstacles and tripping hazards for athletes when moving or turning, as well as slipping and falling in the same direction. Uneven grass fiber lying makes the turf surface uneven, severely limiting the ball's rolling speed and distance. Because the existing grass clumps are arranged in a linear, straight fiber pattern, this arrangement prevents the grass clumps from forming a cross-network pattern. After installation and infilling, the grass fiber distribution on the turf surface will be uneven and uneven, affecting the sports experience and fairness. Straight fibers lying flat will also accelerate wear, seriously affecting the quality of the turf.

[0004] Therefore, we need a type of lawn to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention proposes an artificial turf and turf system for competitive sports, which solves the problem of loose grass clumps affecting turf quality in related technologies.

[0006] The technical solution of this utility model is as follows:

[0007] An artificial turf for competitive sports includes a base fabric layer, a grass tuft layer, and an adhesive layer. The adhesive layer is located at the bottom of the base fabric layer, and the grass tuft layer passes through the base fabric layer. The bottom of the grass tuft layer and the adhesive layer form a protrusion, and a plurality of the protrusions are continuously distributed along a curved direction.

[0008] As a further technical solution, the grass clump layer includes,

[0009] The woven clusters are numerous and distributed along a curved direction on the base fabric layer.

[0010] Braided yarns pass through the braided clusters, and several of the braided clusters are connected by the braided yarns.

[0011] As a further technical solution, the woven cluster includes a plurality of curved filaments and woven fabric, wherein the plurality of curved filaments are all connected to the woven fabric, the plurality of woven fabrics are connected through the woven filaments, the plurality of curved filaments are curved, and the plurality of curved filaments are interwoven with each other.

[0012] As a further technical solution, the height of the knitted cluster is 8-80mm, the row spacing is 1 / 10-3 / 4 inch, and the stitch count is 80-500 stitches / meter.

[0013] As a further technical solution, the braided cluster also includes a number of straight filaments, which are connected to the braided fabric, and the number of curved filaments are distributed interlaced with the straight filaments.

[0014] As a further technical solution, the materials of the curved filament and the straight filament are one or two of new material polymers such as PP, PE, TPU or nylon.

[0015] As a further technical solution, the height of the bent wire is 0.3 to 0.4 times the height of the straight wire, and the maximum outer diameter of the bent wire is not greater than the maximum outer diameter of the straight wire after it is spread out.

[0016] As a further technical solution, it includes any type of artificial turf for sports competitions, an infill layer, and a shock-absorbing pad layer distributed from top to bottom, wherein the shock-absorbing pad layer is in contact with the ground.

[0017] As a further technical solution, the filling layer includes a quartz sand layer and a particle layer, which are distributed vertically from top to bottom and are evenly distributed between the grass clumps.

[0018] The working principle and beneficial effects of this utility model are as follows:

[0019] In order to solve the above-mentioned technical problems, this utility model proposes an artificial turf and turf system for competitive sports, including a base fabric layer, a grass tuft layer and an adhesive layer. The adhesive layer is located at the bottom of the base fabric layer. The grass tuft layer passes through the base fabric layer, and the grass tuft layer and the adhesive layer form protrusions. Several protrusions are continuously distributed along a curved direction. The base fabric layer is used for installation on the ground. The grass tuft layer is woven into the base fabric layer, and the bottom of the grass tuft layer is connected by the adhesive layer, making the connection more secure. The bottom of the grass tuft layer passes through the adhesive layer to form protrusions. The protrusions are distributed along a curve, so that the woven tufts of the grass tuft layer are distributed along a curve, thereby making the spacing between the grass tuft layers smaller and the distribution more reasonable. The protrusions can also be arranged in a linear direction, but the linear arrangement is not as good as the curved arrangement, which is more compact.

[0020] Beneficial Effects: The grass fibers utilize a unique, naturally curled, and non-directional cross-weaving process. This process ensures an extremely smooth surface, providing athletes with a stable and comfortable playing surface. A variety of weaving patterns are employed between the grass tufts and the backing fabric, including Z, ─, W, M, S, ∽, and ≈, among others. This results in a highly natural distribution of the grass tufts, making the entire field highly realistic, as if one were on a natural lawn. Simultaneously, this weaving method greatly enhances the pull-out force of the grass fibers, making them stronger and significantly improving durability. It can withstand high-intensity use for extended periods, and the surface grass fibers exhibit a delicate, naturally curled, and cross-woven structure. Even if athletes fall during rapid movements, this special grass fiber structure effectively prevents straight grass fibers from puncturing the skin or eyes, ensuring comprehensive safety for athletes.

[0021] The mesh-like, non-directional structure of the surface grass fibers plays a crucial role, especially in rainy or snowy weather. This structure facilitates the rapid infiltration of rainwater and snowmelt, preventing water accumulation on the surface and significantly reducing the risk of athletes slipping and falling, thus ensuring that the competition can be conducted safely and smoothly under various weather conditions.

[0022] Thanks to the non-directional cross-grass fibers and the naturally flat mesh surface, the turf performs exceptionally well in ball sports. The ball's rebound, rolling speed, and rolling distance all precisely meet the standards stipulated for international competitions, providing athletes with a top-level competitive sports experience and ensuring both the competitiveness and spectator appeal of the game.

[0023] The grass fibers have a coiled, spring-like structure, giving them excellent resilience. Even after prolonged trampling, the grass fibers can still return to their original state thanks to this unique structure, maintaining the lawn's excellent performance and providing athletes with consistent and stable motion feedback.

[0024] The coiled spring mesh structure of the surface grass fibers provides excellent mechanical properties. It can quickly and efficiently disperse, absorb, and reduce the impact force generated by each foot strike, exerting a superior shock absorption and cushioning effect. It's like equipping the athlete's feet with a reliable "protective pad," effectively preventing sports injuries and allowing athletes to fully immerse themselves in intense competition without any worries.

[0025] The lawn uses a multi-layer composite base fabric and corrosion-resistant adhesive material. This high-quality material combination greatly extends the overall lifespan of the lawn and reduces the cost and resource consumption caused by frequent lawn replacement. From a long-term perspective, it has a high cost-performance ratio.

[0026] In addition, the turf and shock-absorbing pads are installed and used in accordance with standards, strictly following the relevant standards for domestic and international competition-level venues. This ensures that the entire venue system, from basic construction to actual use, perfectly meets the stringent requirements of various high-level competitive events, laying a solid foundation for the successful hosting of the events.

[0039] Example 1

[0040] Reference Figures 1-6 This is the first embodiment of the present invention, which proposes an artificial turf for competitive sports, including a base fabric layer 1, a grass tuft layer 2 and an adhesive layer 3. The adhesive layer 3 is located at the bottom of the base fabric layer 1, the grass tuft layer 2 passes through the base fabric layer 1, and the bottom of the grass tuft layer 2 forms a protrusion with the adhesive layer 3. Several of the protrusions are continuously distributed along the curved direction.

[0041] In order to solve the above-mentioned technical problems, this utility model proposes an artificial turf and turf system for competitive sports, including a base fabric layer 1, a grass tuft layer 2, and an adhesive layer 3. The adhesive layer 3 is located at the bottom of the base fabric layer 1. The grass tuft layer 2 passes through the base fabric layer 1, and the grass tuft layer 2 and the adhesive layer 3 form a protrusion. Several protrusions are continuously distributed along the curve direction. The base fabric layer 1 is used to install on the ground. The grass tuft layer 2 is woven onto the base fabric layer 1. The bottom of the grass tuft layer 2 is then connected by the adhesive layer 3, making the connection more secure. The bottom of the grass tuft layer 2 passes through the adhesive layer 3 to form a protrusion. The protrusion is distributed along the curve, so that the woven tufts 4 of the grass tuft layer 2 are distributed along the curve, thereby making the spacing between the grass tuft layers 2 smaller and the distribution more reasonable, reducing the risk of separation between the grass tuft layer 2 and the base fabric layer 1.

[0042] Example 2

[0043] Compared to Embodiment 1, the grass tuft layer 2 further includes several woven tufts 4, which are distributed along a curved direction on the base fabric layer 1. The woven yarns 401 pass through the woven tufts 4, and the several woven tufts 4 are connected by the woven yarns 401. Each woven tuft 4 includes several curved yarns 403 and woven fabric 402. The curved yarns 403 are all connected to the woven fabric 402, and the woven fabric 402 is connected by the woven yarns 401. The curved yarns 403 are curved and interlaced. The height of the woven tuft 4 is 8-80 mm, the row spacing is 1 / 10-3 / 4 inch, and the stitch count is 80-500 stitches / meter. The woven tuft 4 also includes several straight yarns 404, which are connected to the woven fabric 402, and the curved yarns 403 are interlaced with the straight yarns 404. The bent filament 403 and the straight filament 404 are made of one or two of new material polymers such as PP, PE, TPU, or nylon. The height of the bent filament 403 is 0.3 to 0.4 times the height of the straight filament 404, and the maximum outer diameter of the bent filament 403 is not greater than the maximum outer diameter of the straight filament 404 after it is spread out.

[0044] In this embodiment, the grass tuft layer 2 includes a woven tuft 4, which is woven into shape and woven on the base fabric layer 1. The woven fabric 402 at the bottom of the woven tuft 4 is used to connect with the base fabric layer 1. The curved yarn 403 is curved and the straight yarn 404 is linear. The straight yarn 404 can increase the friction between the grass tuft layer 2 and the sole of the person's shoe, while the curved yarn 403 can increase the aesthetics of the grass tuft layer 2 and reduce wear. The curved yarn 403 and the straight yarn 404 are distributed alternately, which can also increase the friction between them and reduce the damage to the grass tuft layer 2.

[0045] Example 3

[0046] Compared to Embodiments 1-2, this embodiment further provides a sports artificial turf system, comprising, from top to bottom, a structurally robust turf as described in Embodiment 1 or 2, an infill layer 5, and a shock-absorbing pad layer 6, with the shock-absorbing pad layer 6 in contact with the ground. The infill layer 5 includes a quartz sand layer 501 and a granular layer 502, which are distributed vertically from top to bottom and are evenly distributed between the turf clumps 2. The quartz sand particles in the quartz sand layer 501 are of uniform size, and the granular layer 502 uses rubber granules, providing good elasticity and cushioning performance for the entire turf system.

[0047] In practical applications, this tightly structured turf and turf system, due to the special design of the grass tuft layer 2, no longer features grass fibers that are neatly tilted in one direction like traditional artificial turf. The height and uprightness of the grass fibers are no longer uniform, thus reducing hindrance to athletes' movement and lowering the risk of falls. Furthermore, the grass tufts are evenly and densely distributed, reducing wear and tear and significantly improving the quality and lifespan of the turf. Whether in sports fields, landscaping, or home decoration, it exhibits excellent performance and a beautiful appearance.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
