Description

Technical Field

[0001] This utility model belongs to the field of artificial turf processing technology, specifically relating to an infill-free artificial turf with a coiled fiber buffer structure. Background Technology

[0002] When artificial turf is manufactured using a tufting process, grass fibers are implanted into a base fabric in a tufted manner to form the turf surface. An adhesive backing is then applied to the back of the base fabric to secure the grass fibers and prevent them from falling off. Artificial turf produced using this traditional method has poor cushioning performance, requiring the filling of the gaps between the grass fibers with cushioning quartz sand or rubber granules to increase its cushioning capacity. This results in environmental hazards and high maintenance costs associated with artificial turf. Utility Model Content

[0003] The purpose of this invention is to provide an infill-free artificial turf with a coiled fiber buffer structure to solve the problem of poor buffering performance of artificial turf without infill.

[0004] The present invention provides a non-fillable artificial turf with a coiled fiber buffer structure, which is achieved as follows:

[0005] An infill-free artificial turf with a coiled cushioning structure includes a base fabric layer, a grass fiber layer woven on the base fabric layer, and an adhesive layer coated on the back of the base fabric layer.

[0006] The grass fiber layer includes straight grass fibers and coiled curly fibers. The coiled curly fibers are closed loops and are arranged in a continuous S-shape or wavy shape.

[0007] Furthermore, the height of the coiled filaments is 1 / 3 to 1 / 2 of the height of the straight filaments.

[0008] Furthermore, the height of the straight grass fibers is 15-60mm.

[0009] Furthermore, the height of the coiled filament is 8-25mm.

[0010] Furthermore, the diameter of the closed loop formed by the coiled filament is 5-20 mm.

[0011] Furthermore, the straight grass fibers are made of PE or PP blends.

[0012] Furthermore, the coiled filaments are made of TPE elastic material.

[0013] Furthermore, the looped filaments pass through the base fabric layer in the form of continuous coils, and their weaving density is 8000-12000 bundles / ㎡.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0015] This invention, through its circular curved filament design, not only ensures good cushioning performance of artificial turf with zero filling and improves its environmental friendliness, but also disperses stress, reduces the breakage of straight filaments, and lowers the probability of damage and maintenance costs of artificial turf.

[0021] 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.

[0022] 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.

[0023] Example 1

[0024] like Figure 1-2As shown, an infill-free artificial turf with a coiled cushioning structure includes a base fabric layer 1, a grass fiber layer 2 woven on the base fabric layer 1, and an adhesive layer 3 coated on the back of the base fabric layer 1; the grass fiber layer 2 includes straight grass fibers 21 and coiled filaments 22, the coiled filaments 22 being closed loops and in a continuous S-shape.

[0025] The looped filaments 22 have certain elastic deformation characteristics. That is, they absorb impact force through the expansion and contraction of the looped structure, so that the artificial turf has spring-like cushioning performance. Furthermore, arranging the looped filaments 22 in a continuous S-shape can not only ensure the cushioning performance of the artificial turf, but also disperse the stress on the artificial turf and reduce the probability of the straight filaments 21 breaking.

[0026] In this embodiment, both straight grass fibers 21 and looped filaments 22 are woven onto the base fabric layer 1 using a tufting method. The straight grass fibers 21 are normally formed into linear grass fibers through tufting and cutting using tufting needles, hooks, and cutters. The looped filaments 22 can be formed into loops using tufting needles and hooks, but without the need for cutting with a cutter, directly forming a looped structure. After weaving, the fibers undergo heat treatment in a drying tunnel, causing the looped grass fibers to shrink and form the looped filaments 22.

[0027] In the above processing, since the coiled wire 22 does not need to be cut, the cutting loss of the coiled wire 22 can be saved, reducing the raw material consumption of the coiled wire 22 by about 20%.

[0028] To ensure the cushioning effect of the artificial turf, the height of the coiled filaments 22 is 1 / 3 to 1 / 2 the height of the straight filaments 21.

[0029] Preferably, the height of the straight grass fibers 21 is 15-60mm.

[0030] In artificial turf, straight grass fibers 21 play a supporting role. Selecting straight grass fibers 21 of this height can provide the artificial turf with an upright appearance and ensure its wear resistance.

[0031] Preferably, the height of the coiled wire 22 is 8-25mm.

[0032] The use of looped filaments 22 within this height range provides additional elastic deformation space, effectively ensuring the cushioning performance of the artificial turf. Furthermore, testing shows that the artificial turf of this embodiment offers over 40% better cushioning performance compared to traditional artificial turf.

[0033] To ensure the elastic deformation space of the coiled wire 22, the diameter of the closed loop formed by the coiled wire 22 is 5-20mm.

[0034] Straight grass fiber 21 is a PE or PP blend material with a hardness ≥90 Shore D.

[0035] The coiled filament 22 is a TPE elastic material with a hardness of 60-80 Shore A and an elastic modulus ≤500MPa, exhibiting excellent elastic properties.

[0036] To ensure the cushioning performance of the artificial turf, the looped filaments 22 pass through the base fabric layer 1 in the form of continuous loops, and their weaving density is 8000-12000 bundles / ㎡.

[0037] The root of the straight grass filament 21 is connected to the root of the coiled filament 22. Since the coiled filament 22 is not cut off, the firmness of the straight grass filament 21 can be guaranteed to a certain extent.

[0038] Example 2

[0039] like Figure 3 As shown, based on Example 1, this embodiment also provides an infill-free artificial turf with a coiled fiber buffer structure. Its structure is roughly the same as that of Example 1, except that...

[0040] The coiled filaments 22 are arranged in a wavy pattern.

[0041] The artificial turf of this invention, through the design of the looped filaments 22, can improve its cushioning performance by more than 40%, and eliminates the need for filling with rubber granules or other fillers, thus avoiding environmental hazards. At the same time, the looped filaments 22 can also disperse the stress on the artificial turf, reduce the breakage of straight filaments, lower the probability of damage and maintenance costs. In addition, the looped filaments 22 do not require cutting during weaving, which can save the waste caused by cutting, reduce the amount of raw materials used for the looped filaments 22, and lower processing costs.

[0042] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
