Description

Technical Field

[0001] This utility model relates to the technical field, specifically to an improved antistatic cotton cloth. Background Technology

[0002] Antistatic cotton fabric is a functional fabric based on a multi-layer composite structure. It uses cotton as a base and achieves antistatic performance through a composite conductive antistatic layer. The surface layer ensures skin-friendliness and breathability, the middle layer is a conductive functional layer that builds a charge conduction channel, and the bottom layer can be stacked with a reinforcement or moisture-absorbing layer to improve practicality. It quickly conducts and dissipates the static charge accumulated on the surface of the fabric through the middle layer, avoiding charge accumulation. The composite process often uses lamination and coating.

[0003] In the current technology, this cotton fabric is often used in clothing manufacturing. Although traditional cotton fabric has natural advantages such as softness, breathability, and moisture absorption, it is very easy to generate static electricity when it rubs against other materials or is in a special environment. In the past, auxiliary agents were often used to solve the static electricity problem of cotton fabric. However, this method has obvious defects. After multiple washes, the anti-static effect will be greatly reduced and it is difficult to play a stable role in the long term. At the same time, some existing anti-static fabrics are relatively simple in terms of functionality and cannot meet the comprehensive needs of waterproofing, heat insulation, moisture absorption and sweat wicking, and antibacterial properties in actual use. Utility Model Content

[0004] (a) Technical problems to be solved In view of the shortcomings of the existing technology, this utility model provides an improved antistatic cotton cloth, which solves the problem that traditional cotton cloth has relatively simple functions and cannot meet the comprehensive needs of waterproofing, heat insulation, moisture absorption and sweat wicking and antibacterial properties in actual use.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: it includes a surface protective layer, an antistatic charge distribution layer, a liquid blocking layer, a thermal insulation buffer layer, a moisture-wicking layer, and an antibacterial contact layer. The surface protective layer, the antistatic charge distribution layer, the liquid blocking layer, the thermal insulation buffer layer, the moisture-wicking layer, and the antibacterial contact layer are connected sequentially from top to bottom. A hot melt adhesive layer is provided on the side of the surface protective layer near the antistatic charge distribution layer. The liquid blocking layer and the thermal insulation buffer layer are connected by hot pressing.

[0006] Preferably, the surface protective layer has a protective coating on the side away from the hot melt adhesive layer, and the surface protective layer is made by weaving.

[0007] Preferably, the antistatic charge distribution layer comprises stainless steel fibers and carbon fibers, wherein the stainless steel fibers and carbon fibers are configured as a two-way mesh.

[0008] Preferably, a hydrophilic thermoplastic polyurethane film is disposed between the liquid blocking layer and the thermal insulation buffer layer, the hydrophilic thermoplastic polyurethane film being used to assist in the thermal pressing connection between the liquid blocking layer and the thermal insulation buffer layer.

[0009] Preferably, the thickness of the surface protective layer is 0.3 mm.

[0010] Preferably, the thermal insulation buffer layer comprises an aerogel nonwoven fabric, wherein the aerogel nonwoven fabric is configured with a nanoporous structure.

[0011] Preferably, the liquid blocking layer comprises an expanded polytetrafluoroethylene film, wherein the expanded polytetrafluoroethylene film is porous.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides an improved antistatic cotton cloth, which has the following beneficial effects: 1. This utility model features an antistatic charge distribution layer. During use, the antistatic charge distribution layer comprises stainless steel fibers and carbon fibers arranged in a bidirectional mesh. The stainless steel fibers provide extremely low and stable volume resistivity, while the carbon fibers supplement the conductive path and enhance the overall integrity of the material. Static charges generated at any point can be quickly captured and evenly distributed along the mesh, rather than forming high-voltage points. Finally, the charges are safely dissipated through grounding or air ion neutralization. This significantly enhances the antistatic performance of the cotton fabric during use. Furthermore, the surface protective layer protects the antistatic charge distribution layer, preventing wear and further improving the antistatic performance of the cotton fabric and extending its service life.

[0013] 2. This utility model, by setting a hydrophilic thermoplastic polyurethane film, ensures that the liquid blocking layer itself is non-adhesive during use. When pressing the liquid blocking layer and the thermal insulation buffer layer, the hydrophilic thermoplastic polyurethane film, which is a solid barrier when dry, becomes active in molecular chain movement upon contact with moisture, allowing water vapor to pass through. In actual use, this hydrophilic thermoplastic polyurethane film ensures the overall device's own air permeability while blocking external moisture, resulting in better performance during use.

[0016] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0017] This utility model provides a technical solution: Please see Figures 1-3 An improved antistatic cotton fabric, comprising the following technical solution to achieve the above-mentioned objectives: including a surface protective layer 1, an antistatic charge distribution layer 2, a liquid blocking layer 3, a thermal insulation buffer layer 4, a moisture-wicking layer 5, and an antibacterial contact layer 6, wherein the surface protective layer 1, the antistatic charge distribution layer 2, the liquid blocking layer 3, the thermal insulation buffer layer 4, the moisture-wicking layer 5, and the antibacterial contact layer 6 are connected sequentially from top to bottom; a hot melt adhesive layer 7 is provided on the side of the surface protective layer 1 closest to the antistatic charge distribution layer 2; the liquid blocking layer 3 and the thermal insulation buffer layer 4 are connected by hot pressing; a protective coating layer 8 is provided on the side of the surface protective layer 1 away from the hot melt adhesive layer 7; and the surface protective layer 1 is woven, with a thickness of 0.3 mm.

[0018] It should be noted that the surface protective layer 1 is made of high-performance nylon. During manufacturing, it is produced by spinning to form thick and tough filament fibers. Blending it with cotton balances the rigidity and dyeability of pure nylon, while introducing the hygroscopic properties of cotton to facilitate subsequent lamination and bonding. This results in surface protective layer 1 having good protective performance. The thickness of surface protective layer 1 is set to 0.3 mm. In actual use, the protective coating 8 added to the outside of surface protective layer 1 and the set thickness significantly enhance its abrasion resistance and tear resistance, allowing it to withstand friction and more severe impacts for longer periods. The surface protective layer 1 and the antistatic charge distribution layer 2 are connected by a hot melt adhesive layer 7, enabling surface protective layer 1 to better protect the antistatic charge distribution layer 2 during use, reducing damage to the antistatic charge distribution layer 2 and strengthening the antistatic performance of the cotton fabric.

[0019] The antistatic charge distribution layer 2 includes stainless steel fibers and carbon fibers, which are arranged in a two-way mesh.

[0020] It should be noted that the aforementioned antistatic charge distribution layer 2 is made of stainless steel fiber and carbon fiber. In practical use, stainless steel fiber and carbon fiber are blended in a two-way mesh. Stainless steel fiber provides extremely low and stable volume resistivity, while carbon fiber supplements the conductive path and enhances the overall integrity of the material. Static charges generated at any point can be quickly captured and evenly distributed along the mesh, rather than forming high voltage points. Finally, the charges are safely dissipated through grounding or air ion neutralization. The use of two conductive materials provides performance redundancy, so that if one fails, the other can still work, greatly improving reliability and making the cotton fabric perform better in use.

[0021] A hydrophilic thermoplastic polyurethane film 9 is provided between the liquid blocking layer 3 and the thermal insulation buffer layer 4. The hydrophilic thermoplastic polyurethane film 9 is used to assist in the hot-pressing connection between the liquid blocking layer 3 and the thermal insulation buffer layer 4.

[0022] It should be noted that since the liquid blocking layer 3 itself is not adhesive, the hydrophilic thermoplastic polyurethane film 9 added between the liquid blocking layer 3 and the thermal insulation buffer layer 4 can assist in the hot-pressing connection of the liquid blocking layer 3 and the thermal insulation buffer layer 4. Moreover, the hydrophilic thermoplastic polyurethane film 9 is a solid barrier when dry, and its molecular chain movement becomes active when it encounters water vapor, allowing water vapor to pass through. Compared with the prior art, the hydrophilic thermoplastic polyurethane film 9 itself is breathable, thus achieving breathable bonding.

[0023] The thermal insulation buffer layer 4 includes an aerogel nonwoven fabric, which is configured as a nanoporous structure.

[0024] It should be noted that the thermal insulation buffer layer 4 material mentioned above is aerogel nonwoven fabric. Due to its nanoporous structure and the fact that more than 90% of it is air, aerogel effectively suppresses the three heat transfer modes: weak air convection, heat convection, and heat radiation. The thermal insulation performance of the aforementioned aerogel nonwoven fabric does not depend on its thickness; an extremely thin layer can provide excellent thermal insulation. At the same time, its soft solid form also provides good cushioning and energy absorption performance.

[0025] The liquid blocking layer 3 includes an expanded polytetrafluoroethylene film, which is porous.

[0026] It should be noted that the liquid barrier layer 3 is made of expanded polytetrafluoroethylene film. In actual use, because the expanded polytetrafluoroethylene film is porous, liquid water cannot penetrate these pores. Breathability is achieved through concentration gradient. Water vapor molecules emitted by the body can freely diffuse to the outside through the micropores, achieving breathable protection. This makes the cotton fabric more breathable and solves the problem of traditional waterproof fabrics being non-breathable.

[0027] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
