Description

Technical Field

[0001] This utility model relates to the field of artificial turf technology, and more specifically to a high-density, high-low grass artificial turf. Background Technology

[0002] Artificial turf is widely used in sports fields, landscaping, and home decoration due to its exquisite and neat 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, artificial turf produced is relatively uniform, with grass fibers typically tilted in one direction. The height and uprightness of the grass fibers tend to be consistent, making it appear rather stiff and lifeless compared to natural grass. Patent CN202110864538.7 proposes a method for manufacturing high-low grass artificial turf. This method uses grass fibers of different heights and materials, processed using a single-screw extruder, combined with a hot water tank and shaping rollers to form naturally draping high straight fibers and supporting low straight fibers. These are then combined with curved fibers through a paralleling process and fixed to a base fabric. After high-temperature heating, a layered, non-directional turf with varying heights is formed. However, this method has very strict requirements on the material of the grass fibers and the heat treatment process, resulting in low production efficiency and high control difficulty.

[0003] Therefore, how to provide a high-low grass artificial turf is a problem that urgently needs to be solved by experts in this field. Utility Model Content

[0004] This utility model aims to at least partially solve one of the aforementioned technical problems in the prior art.

[0005] Therefore, one objective of this utility model is to provide a high-density high-low grass artificial turf, which achieves one-time tufting through double-row tufting technology and grass fiber structure design. The height difference between the first and second fiber clusters can be adjusted as needed, and the turf fibers do not require special treatment, which greatly improves production efficiency and the simulation effect of the turf.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-density, high-low grass artificial turf comprises a base fabric layer, an adhesive layer, and a grass fiber layer. The adhesive layer is located at the bottom of the base fabric layer, and the grass fiber layer is formed by tufting the grass fibers onto the top of the base fabric layer in a single pass using double-row tufting needles, creating double rows of turf fibers.

[0067] As can be seen from the above technical solution, compared with the prior art, this utility model has the following technical effects:

[0068] The high-density, high-low grass artificial turf provided by this utility model achieves one-time tufting molding through double-row tufting technology and grass fiber structure design. This breaks the characteristic of traditional artificial turf that can only have equal row spacing. The turf fiber row spacing is arranged at unequal intervals. At the same time, it also breaks the characteristic of traditional turf tufting cutting that can only have equal fiber heights. The height difference between the first fiber tuft and the second fiber tuft can be adjusted within the range of 5-12mm. The unequal spacing and unequal height design results in clear turf layers, achieves a non-directional turf effect, and provides better turf simulation, making it closer to the appearance of natural grass.

[0069] This invention provides a high-density, high-low grass artificial turf that utilizes large-area tufting needles with threading holes, enabling the production of high-weight turf fibers. This breaks the limitations of traditional high-density artificial turf on fiber DTEX, significantly improving tufting production efficiency. By employing artificial turf fibers with different DTEX and types, both sports and leisure artificial turf can be achieved. Furthermore, because the artificial turf fibers in the second tufting needle are lower in height than those in the first tufting needle, this does not affect the cost of the artificial turf. It also effectively solves the problem of color difference on the carpet surface caused by protruding tufts in traditional artificial turf.

[0070] The high-density high-low grass artificial turf provided by this utility model can achieve the dense carpet effect of conventional high-DTEX turf production using low-DTEX artificial turf fibers, while being more cost-effective. Attached Figure Description
