Abstract
Description
Technical Field
[0001] This utility model belongs to the field of artificial turf technology, specifically relating to an artificial turf made entirely of PE material. Background Technology
[0002] Existing artificial turf uses different materials for the grass fibers and the backing fabric. This multi-material mixing requires separation during recycling, leading to high costs and a decline in the quality of recycled materials. Furthermore, to prevent grass fibers from detaching, this type of artificial turf requires an adhesive backing on the back of the backing fabric. The presence of this adhesive layer not only hinders turf recycling but also makes the grass fibers prone to shedding after long-term use due to aging of the adhesive layer. Additionally, because the adhesive layer completely seals the backing fabric, extra perforation is required, making the process cumbersome and prone to clogging. Utility Model Content
[0003] The purpose of this invention is to provide an artificial turf made entirely of PE material to solve the problem of high recycling costs for artificial turf.
[0004] The artificial turf made entirely of PE material according to this utility model is achieved as follows:
[0005] An artificial turf made entirely of PE material includes a warp-knitted base layer and a grass fiber layer woven onto the warp-knitted base layer by warp knitting, wherein the warp-knitted base layer and the grass fiber layer are woven together in one piece;
[0006] The warp-knitted base mesh layer and the grass fiber layer are both woven from 100% PE yarn;
[0007] The warp-knitted bottom layer is either a permeable mesh type or a dense mesh type;
[0008] The grass fiber layer comprises a plurality of grass fibers fixed on the warp-knitted base layer by a weaving method.
[0009] Furthermore, the permeable mesh type warp-knitted bottom layer is provided with a number of mesh holes, the mesh hole diameter being 2mm-50mm.
[0010] Furthermore, the mesh openings are square, rhomboid, or hexagonal.

[0012] Furthermore, the warp-knitted bottom layer of the dense mesh type has a chain-knitted structure with a porosity of <5%.
[0013] Furthermore, the roots of the grass fibers are fixed to the braided structure by means of mechanical locking with coils.
[0014] Furthermore, the warp-knitted bottom layer is woven from 500-1500D composite yarn.
[0015] Furthermore, the grass fibers are flat fibers with a width of 0.5mm-2mm and a height of 10mm-40mm.
[0016] Furthermore, the grass fibers are straight fibers, curved fibers, or a combination of both.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0029] Example 1
[0030] like Figure 1-3 As shown, an artificial turf made entirely of PE material includes a warp-knitted base mesh layer 1 and a grass fiber layer 2 woven onto the warp-knitted base mesh layer 1 by warp knitting. The warp-knitted base mesh layer 1 and the grass fiber layer 2 are woven together in one piece. The warp-knitted base mesh layer 1 and the grass fiber layer 2 are both woven from 100% PE yarn. The warp-knitted base mesh layer 1 has a permeable mesh type. The grass fiber layer 2 includes a number of grass fibers 3 fixed onto the warp-knitted base mesh layer 1 by weaving.
[0031] Among them, 100% PE yarn refers to fiber yarn made entirely from polyethylene resin through processes such as melt spinning and drawing.
[0032] During the weaving process, double combs (i.e., ground comb and mesh comb) are used to weave the warp-knitted base layer 1. The ground comb weaves an open chain weave to form a longitudinal skeleton, while the mesh comb weaves the weft to form the mesh boundary. The grass fibers 3 are woven by the third comb onto the nodes of the mesh 4 in a weft-weaving manner.
[0033] To ensure the permeability of the warp-knitted base layer 1, a number of mesh holes 4 are provided on the permeable mesh type warp-knitted base layer 1, with the mesh hole diameter of 4 being 2mm-50mm.
[0034] In this embodiment, the mesh 4 is square.
[0035] The roots of grass fibers 3 are woven and fixed onto the mesh structure.
[0036] The warp-knitted bottom layer 1 is woven from 500-1500D composite yarn.
[0037] Grass fiber 3 is a flat wire with a width of 0.5mm-2mm and a height of 10mm-40mm.
[0038] Grass fibers 3 can be straight fibers 31, curved fibers 32, or a combination of the two types of grass fibers 3.
[0039] In this embodiment, the grass fibers 3 are a combination of straight fibers 31 and curved fibers 32, which can increase the elasticity of the artificial turf.
[0040] Specifically, in this embodiment, 1000D PE composite yarn is used to weave the warp-knitted base layer 1, and 1.2mm (width) * 25mm (height) PE flat yarn is selected as the grass fibers 3, which are woven in one go. After weaving, a heat-setting treatment is performed, with the temperature controlled at 120°-135° to stabilize the size of the artificial turf, prevent the grass fibers 3 from lying down, and enhance the pull-out force of the grass fibers 3. Finally, a nano-level PE-based hydrophobic coating can be applied to the surface of the artificial turf to improve its stain resistance, water resistance, and corrosion resistance.
[0041] The artificial turf disclosed in this embodiment has a water permeability of 980L / (㎡*s), a grass fiber pull-out force of 126N, and can be machine washed more than 50 times in 40° water.
[0042] Therefore, it can be seen that the artificial turf of this utility model has good water permeability, the grass fibers 3 are firmly fixed and there will be no problem of grass fibers 3 falling off, it is easy to clean, and the recycling method is simple and low cost.
[0043] Example 2
[0044] Based on Example 1, this example also provides an artificial turf made entirely of PE material, wherein the warp-knitted bottom mesh layer 1 is a dense mesh bottom type, and the dense mesh bottom type warp-knitted bottom mesh layer 1 has a chain structure with a porosity of <5%.
[0045] The three grass fibers are fixed to the chain structure by means of mechanical locking with coils.
[0046] During the weaving process, the three guide bars are fully woven, with two guide bars forming a dense base mesh (warp plain weave), and the third guide bar forming a loop on the base mesh, which is then fixed to the base mesh by a mechanical locking method using loops.
[0047] Among them, the mechanical locking of the coil is one of the important characteristics of warp-knitted fabrics. That is, during the warp knitting process, the bottom net coil and the grass fiber 3 coil are fixed and hooked together by mechanical force, thereby improving the firmness of the grass fiber 3, preventing the grass fiber 3 from falling off, and improving the strength and durability of the entire artificial turf.
[0048] The artificial turf produced in this embodiment can be permeable to water through the gaps in the warp-knitted bottom layer 1, with a permeability rate >1L / (㎡*s). Compared with other dense artificial turf, its permeability is greatly improved, effectively solving the problem of water accumulation in dense turf.

[0053] like Figure 5 As shown, based on Example 1, this example also provides an artificial turf made entirely of PE material, whose structure is roughly the same as that of Example 1, except that...
[0054] The shape of mesh 4 is hexagonal.
[0055] The shape of mesh 4 is not limited to square, rhombus or hexagon; the shape of mesh 4 can be selected according to needs.
[0056] The artificial turf provided by this invention uses a single PE material, which can be directly melted and recycled. Compared with artificial turf made of other mixed materials, the recycling cost is reduced by more than 60%. Furthermore, its one-piece warp-knitting method effectively ensures the pull-out force of the grass fibers 3, guaranteeing the strength of the grass fibers 3 without the need for backing adhesive. The manufacturing process is simple and low-cost. In addition, this invention allows for the selection of permeable mesh or dense mesh artificial turf according to application needs, making it suitable for various scenarios such as pet waste disposal, sports and leisure, and landscaping, thus offering greater versatility.
