Description

Technical Field

[0001] The utility model relates to the technical field of artificial turf, and more specifically, to a low-profile non-reverse artificial turf. Background Art

[0002] Artificial turf is usually woven separately from straight fibers or woven from a mixture of straight fibers and bent fibers. The straight fibers are linear and have good standing properties and are not easily bent. Due to subsequent mechanized unified processes, the straight fibers usually show a state of being straight and inclined in the tufting direction on the artificial turf carpet surface. Especially in artificial turf with a lower grass height, the single-inclination front-thorn phenomenon is particularly serious.

[0003] At the same time, in terms of the use performance of artificial turf, the single-direction inclination of the grass filaments will affect the direction trend of people walking and moving, showing a "slippery" feeling. In some sports fields, in order to meet the sports performance of artificial turf, due to a large amount of filling material, the height of the exposed top grass filaments is limited, greatly reducing the natural simulation effect of the lawn. Moreover, the single reverse also affects the sports performance.

[0004] Therefore, how to provide an artificial turf with a better simulation effect, which can meet the requirements of sports performance, and at the same time can improve the reverse property of the grass filaments is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0005] The utility model aims to solve at least one of the above technical problems in the prior art to a certain extent.

[0006] For this reason, an object of the utility model is to provide a low-profile non-reverse artificial turf.

[0007] In order to achieve the above object, the utility model adopts the following technical scheme:

[0008] A low-profile non-reverse artificial turf, comprising: grass filaments, a base cloth and a back glue. The grass filaments are fixed on the base cloth through the back glue. The grass filaments at least include one kind of low-profile straight filament fiber, and the low-profile straight filament fiber is used as the top grass filament layer and is fixed on the base cloth through the back glue.

[0009] Preferably, the arc radian range of the low-profile straight filament fiber is 30°-90°.

[0010] The beneficial effects of adopting the above technical scheme at least include: the arc radian of the low-profile straight filament fiber designed by the utility model can effectively control and ensure the falling form of the straight filament. Within its range, the top of the straight filament has a certain stretching effect, and at the same time, the root part also maintains a standing property at the connection with the bottom back.

[0011] Preferably, the number of weaving frames of the low-profile straight filament fiber is 50-200 stitches according to the size of the arc radian.

[0012] The beneficial effects of adopting the above technical solution include at least: weaving can give the straight wire a curved shape, and the size of the arc can be effectively adjusted by controlling the number of weaving needles, so that the straight wire can form patterns with different degrees of curvature.

[0013] Preferably, the low-gauze straight filament fiber is warp-knitted, and the length of the low-gauze straight filament fiber is greater than 0.9 compared with the original straight filament fiber.

[0014] The beneficial effects of adopting the above technical solution include at least: the low-yield straight wire fiber designed by the utility model retains the original straight wire height effect on the carpet surface as much as possible, uses low-radian bending arcs to form drooping in different directions, and the height limitation requires that the low-yield straight wire has a lower retraction and shrinkage rate.

[0015] Preferably, the original straight silk fiber is heat-treated and cooled and shaped to obtain the low-yield straight silk fiber.

[0016] Preferably, the low-yield straight filament fiber includes one or more materials selected from PP, PE, PA, POE or TPE.

[0017] Preferably, it further comprises: straight silk fibers and / or curved fibers, wherein the low-yield straight silk fibers and the straight silk fibers and / or curved fibers are tufted on the base fabric in a mixed weaving manner;

[0020] Preferably, the mixed weaving stitching method is straight stitch or Z stitch.

[0021] Preferably, the grass height of the grass yarn is 25-50 mm, the row spacing is 3 / 16-5 / 8 inch, and the needle spacing is 100-400 needles / meter.

[0022] The beneficial effects of adopting the above technical solution include at least: the low-yield straight silk fiber designed in the utility model requires that the grass height cannot be too low or too high, and the row spacing and needle spacing should not be too large, otherwise the upright stretching effect will be lost, and the space between clusters is too large and prone to collapse and sinking, affecting the overall effect.

[0023] Preferably, the cross-sectional shape of the low-yield straight filament fiber includes any one of a rhombus, a rectangle, a triangle, an S-shape, a C-shape, a U-shape, a W-shape, an Ω-shape, and a V-shape, or a combination of multiple thereof.

[0026] Beneficial effects:

[0027] 1) By subjecting the original straight filaments to heat treatment, the present utility model obtains low-profile straight filaments, making the original straight filaments have a low bending arc, and as the top layer of grass filaments, it weakens the regular orientation of the artificial turf, enabling the top layer of grass filaments to develop freely in multiple directions, and at the same time improving the influence of the filament orientation on the sports performance of the artificial turf;

[0028] 2) The low-profile straight filaments designed by the present utility model not only retain the supporting and covering functions of the original straight filaments, but also have a more natural shape;

[0029] 3) The low-profile straight filaments designed by the present utility model are not restricted by the grass filament gram weight, height, material hardness and softness, and shape design, and are a secondary shaping of the original straight filaments;

[0030] 4) The low-profile straight filaments designed by the present utility model can effectively offset the orientation after tufting and curling, and can stretch in multiple directions and fall naturally at the top of the lawn after combing;

[0031] 5) The non-oriented lawn provided by the present utility model can maintain an effective non-oriented effect regardless of whether it is filled or the height of the bottom support grass filaments;

[0032] 6) The non-oriented artificial turf provided by the present utility model has no filament orientation, which has a beneficial effect on improving anti-slip and ball rolling directionality. Description of the Drawings
