AI Technical Summary
The existing artificial turf base cloth is prone to heat deformation during the high-temperature setting process, mainly due to the insufficient high-temperature resistance of PP flat wires and uneven heat conduction.
High-temperature resistant flat wires are used which are alternately stacked with M-layer PET film layer and N-layer thermally conductive layer. The PET film layer has better weather resistance and high-temperature resistance. The thermally conductive layer such as metal foil or graphite products can uniformly transfer heat to avoid deformation caused by local excessive temperatures.
By using this high-temperature resistant flat wire braid, thermal deformation is avoided in the heating furnace, ensuring better tufting effect of artificial turf, and improving the high-temperature resistance of the base cloth.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of artificial turf, and in particular relates to a high temperature resistant flat yarn for a tufted base fabric of an artificial turf. Background Art
[0002] Artificial turf is divided into a base fabric and artificial grass filaments tufted on the base fabric. The base fabric in the prior art is generally woven by PP flat yarn according to the plain weave method. However, after the existing base fabric is tufted and coated with adhesive, it will enter the heating furnace for high-temperature shaping, and the base fabric will be deformed due to heat. There are many reasons for this defect. On the one hand, PP, as the material of the flat yarn, has average weather resistance and high temperature resistance. On the other hand, when the heating furnace heats and shapes the base fabric, the base fabric itself is heated unevenly, and there is a situation where the temperature is too high locally. Therefore, a high-temperature resistant flat yarn is needed as the weaving material of the artificial turf base fabric. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a high temperature resistant flat yarn for artificial turf tufting base fabric, which is used to solve the technical problems that the PP flat yarn in the prior art has poor high temperature resistance and its heat conduction capacity cannot meet the production conditions.
[0004] The utility model solves the above technical problems with the following technical solutions: A high temperature resistant flat yarn for artificial turf tufting base fabric, comprising:
[0005] M PET film layers, M≥2;
[0006] N heat-conducting layers, N≥1, the heat-conducting layers are arranged at intervals between adjacent PET film layers;
[0007] The PET film layer and the heat conductive layer are bonded by glue;
[0008] MN=1.
[0009] The flat yarn of the utility model is formed by alternately stacking PET film layers and heat-conducting layers. Firstly, the PET film layers themselves have better weather resistance and high temperature resistance than PP materials, and the heat-conducting layers can also distribute heat evenly. Especially when in a heating furnace, the heat-conducting layer can quickly transfer local excessively high temperatures to other relatively low-temperature areas, thereby preventing the base cloth woven by the flat yarn of the utility model from being thermally deformed due to excessively high local temperatures in a heating furnace.
[0010] Furthermore: the width range of the high temperature resistant flat wire is 1mm±0.2mm, and the thickness range is 0.05mm±0.01mm.
[0011] The beneficial effect of this step is that since the base fabric is woven in a plain weave method, the flat yarn is used as the warp yarn and needs to be folded and calculated, so the thickness of the warp yarn after folding is actually about 0.1mm; the base fabric woven with the flat yarn of this size as the warp yarn has a suitable yarn density and a good tufting effect.
[0012] Furthermore: the bottom surface of the bottom PET film layer is also provided with protrusions or indentations.
[0013] The beneficial effect of this step: the bumps or indentations are to increase the bottom surface area and friction, so that more adhesive can be applied and the adhesive has stronger adhesion.
[0014] Furthermore: the heat conducting layer is a metal foil.
[0015] The beneficial effect of adopting this step is that the metal foil has good thermal conductivity.
[0016] Furthermore: the heat conducting layer is a graphite product.
[0017] The beneficial effect of adopting this step: Graphite products also have good thermal conductivity and can transfer local high temperature to other relatively low temperature places.
[0018] The beneficial effects of the utility model are:
[0019] The flat yarn in the present application not only changes its material from PP to PET with better weather resistance and high temperature resistance, but also adds a heat-conducting layer between the PET film layers. The heat-conducting layer is used to transfer the local high temperature in the heating furnace to other relatively low temperature areas, so as to avoid deformation of the base cloth woven by the flat yarn of the present application in the heating furnace, so as to ensure a better tufting effect of the artificial turf.

The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.
[0025] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.
[0026] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0027] In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically limited.
[0028] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0029] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0030] Example
[0031] like Figure 1 As shown, the utility model provides a high temperature resistant flat yarn for artificial turf tufting base fabric, comprising:
[0032] M layers of PET film layer 1, M≥2;
[0033] N layers of heat-conducting layers 2, N≥1, the heat-conducting layers 2 are arranged between adjacent PET film layers 1 at intervals;
[0034] The PET film layer 1 and the heat conductive layer 2 are bonded by glue;
[0035] MN=1.
[0036] In the conventional method, the flat wire is first formed into a large-area film and then obtained by die-cutting. Therefore, the PET film layer 1 in the present application is also first independently stretched into a film, and the thermal conductive layer 2 can be sandwiched in the PET film layer, or sprayed onto the surface of the PET film layer 1. The specific preparation method can be selected according to the specific material of the thermal conductive layer 2 (for example, the metal foil is stacked in an interlayer, and the thermal conductive layer 2 cured by spraying a thermal conductive liquid adopts a spraying process). In this way, the film with an overall composite structure can be die-cut to become the flat wire in the present application.
[0037] The flat yarn of the utility model is formed by alternately stacking a PET film layer 1 and a heat-conducting layer 2. Firstly, the PET film layer 1 itself has better weather resistance and high temperature resistance than the PP material, and the heat-conducting layer 2 can also distribute the heat evenly. Especially when in a heating furnace, the heat-conducting layer 2 can quickly transfer the local excessively high temperature to other relatively low temperature places, so that the base cloth woven by the flat yarn of the utility model can be prevented from being thermally deformed due to the excessively high local temperature in the heating furnace.
[0038] On the basis of the above technical solution, the width range of the high temperature resistant flat wire is 1mm±0.2mm, and the thickness range is 0.05mm±0.01mm.
[0039] Since the base fabric is woven in plain weave, the flat yarn is used as the warp yarn and needs to be folded and calculated, so the thickness of the warp yarn after folding is actually about 0.1mm; the base fabric woven with the flat yarn of this size as the warp yarn has a suitable yarn density and a good tufting effect.
[0040] On the basis of the above technical solution, the bottom surface of the bottom PET film layer 1 is further provided with protrusions or indentations.
[0041] The protrusions can be convex points or bosses, and the grooves can be glue grooves or pits. The protrusions or indentations are to increase the area and friction of the bottom surface so that more adhesive can be applied and the adhesive adhesion is stronger.
[0042] Based on the above technical solution, the heat conductive layer is a metal foil, and the metal material can be a metal with good thermal conductivity such as aluminum, copper or silver. The metal foil has good ductility and is not easily damaged during the weaving process as the heat conductive layer 2 of the flat wire.
[0043] Based on the above technical solution, the heat conducting layer is a graphite product.
[0044] The graphite product can be a graphite thermal conductive sheet or a thermal conductive agent doped with graphite particles, etc., which can be sandwiched between the PET film layers 1 or sprayed between the PET film layers 1 and cured to form a thermal conductive layer 2; the graphite product also has good thermal conductivity and can transfer local high temperature to other relatively low temperature areas.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
