Description

Technical Field

[0001] This utility model relates to the field of coated textile fabric technology, specifically a high-temperature resistant coated textile fabric. Background Technology

[0002] Plastic-coated textile fabrics are special materials in which plastic is coated onto the surface of textile fabrics. This treatment can give the fabric additional properties, such as waterproofing, windproofing, breathability, and flame retardancy. The production process of plastic-coated fabrics usually includes two main steps: coating and post-treatment.

[0003] While there are many types of textile fabrics on the market, they often fall short when it comes to the protection required in high-temperature environments. Traditional textile fabrics are usually made of natural or synthetic fibers, which are prone to deterioration or even melting under certain temperature conditions. This limits the application of textile fabrics in certain special industries.

[0004] Currently, the industry generally adopts the method of adding coatings or other chemical treatment agents to ordinary textile fabrics to improve their heat resistance in order to solve this problem. However, such methods generally have the following problems: First, the coating thickness is difficult to control precisely, which leads to a decrease in the breathability of the fabric; second, the coating is easy to fall off after long-term use, thus losing its original protective function; finally, the production process is complex and costly. Therefore, a high-temperature resistant coated textile fabric has been proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-temperature resistant coated textile fabric, which has advantages such as improved adaptability of textile fabric to high-temperature environments. It solves the problems of difficulty in accurately controlling the coating thickness leading to decreased fabric breathability, easy coating peeling after long-term use resulting in loss of original protective function, and complex and costly production process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant coated textile fabric, comprising an upper surface layer covering the outermost layer and a lower surface layer in close contact with human skin, wherein an intermediate layer that provides core protection is provided on the opposite side of the upper and lower surface layers, and a composite layer that enhances the overall strength and stability and promotes tight bonding between multiple layers is provided on the side of both the upper and lower surface layers facing the intermediate layer, wherein an auxiliary cooling mechanism is provided on the lower surface of the lower surface layer for assisting in cooling.

[0007] The auxiliary cooling mechanism includes a cloth bag formed by hot pressing an upper surface layer, a lower surface layer, a middle layer, and a composite layer. Reinforcing ribs are fixed at the four corners of the inner cavity of the cloth bag. A partition cloth is sewn to the left end between the opposite sides of the inner top wall and the inner bottom wall of the cloth bag. A battery is placed in the cavity formed by the cloth bag and the partition cloth on the left side. A miniature fan is fixed in the cavity formed by the cloth bag and the partition cloth on the right side. A fastening cloth is sewn to the top of the front of the cloth bag. A first Velcro fastener is fixed to the lower surface of the fastening cloth. A second Velcro fastener is fixed to the lower surface of the cloth bag.

[0008] By adopting this technical solution, a multi-layered composite structure is used to form a multifunctional composite material that combines aesthetics and practicality. Through the selection and optimization of each component and its reasonable layout, an ideal combination of lightweight, flexibility and excellent physical properties is achieved, enabling the new fabric to not only continue to operate under extreme climatic conditions, but also to maximize the user's experience.

[0009] Furthermore, the upper surface layer is made of high molecular weight polyethylene film, and the thickness of the upper surface layer is 0.05 mm.

[0010] By adopting this technical solution, the upper surface layer is used to resist external high temperature attacks.

[0011] Furthermore, the lower surface layer is made of a cotton-linen blend material, and the thickness of the lower surface layer is 0.2mm.

[0012] By adopting this technical solution, the lower surface layer ensures the wearer's comfort while also wicking away moisture and perspiration.

[0013] Furthermore, the intermediate layer is a glass fiber mesh, and the thickness of the intermediate layer is 0.1 mm.

[0014] By adopting this technical solution, glass mesh serves as a highly efficient insulating and heat-insulating interlayer, further reducing the impact of temperature fluctuations.

[0015] Furthermore, the composite layer is a mesh structure woven from aramid fibers, and polyurethane resin is added to the aramid fibers. The upper surface layer, lower surface layer, middle layer and composite layer are fixed by hot pressing.

[0016] By adopting this technical solution, the composite layer enhances the entire system's ability to resist tearing damage.

[0017] Furthermore, a water-blocking layer is fixed on the upper surface of the intermediate layer, and the water-blocking layer is a microporous PTFE film.

[0018] By adopting this technical solution, the effect of both blocking rainwater and freely releasing water vapor can be achieved.

[0019] Furthermore, the bag is shaped like a cuboid with a hollow interior and a missing front panel, and the size of the fastening fabric is larger than the size of the inner cavity at the notch on the front of the bag.

[0020] By adopting this technical solution, it is ensured that the fastening fabric can block the gap and prevent the battery from falling out of the bag.

[0021] Furthermore, the size of the battery is adapted to the size of the cavity formed on the left side of the bag and the partition cloth, and the micro fan is electrically connected to the battery via a wire.

[0022] By adopting this technical solution, it is ensured that the battery can be inserted and removed, avoiding it from falling out due to its small size.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This high-temperature resistant coated textile fabric adopts a multi-layered composite structure. From the outside in, the fabric includes a wear-resistant and heat-resistant outer cover made of high-density PE film, a high-efficiency insulating and heat-insulating interlayer based on silicone-modified epoxy resin, a comfortable inner lining made of cotton and linen blend yarn for skin-friendly breathability, and a strong and stable frame attached to both the inner and outer sides. This forms a multi-functional composite material that combines aesthetics and practicality. Through the selection and optimization of each component and the rational arrangement of the layout, an ideal combination of lightweight, flexibility and excellent physical properties is achieved. This allows the new fabric to not only continue to operate under extreme climatic conditions, but also to maximize the user's experience. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1 to 2 This embodiment of a high-temperature resistant coated textile fabric includes an upper surface layer 1 covering the outermost layer and a lower surface layer 2 in close contact with human skin. The upper surface layer 1 is mainly used to resist external high temperature attacks. The high molecular weight polyethylene film has extremely high tensile strength and abrasion resistance. The lower surface layer 2 ensures the wearer's comfort while also wicking away moisture and perspiration. An intermediate layer 3 that plays a core protective role is provided on the opposite side of the upper surface layer 1 and the lower surface layer 2. A composite layer 4 that enhances the overall strength and stability and promotes tight bonding between multiple layers is provided on the side of both the upper surface layer 1 and the lower surface layer 2 facing the intermediate layer 3. An auxiliary cooling mechanism 5 for assisting in cooling is provided on the lower surface of the lower surface layer 2.

[0032] The upper layer 1 is made of high molecular weight polyethylene film with a thickness of 0.05mm. The lower layer 2 is a cotton-linen blend material with a yarn ratio of 60% cotton and 40% linen, which is soft and has a good skin-friendly feel. The thickness of the lower layer 2 is 0.2mm. The middle layer 3 is a fiberglass mesh cloth, which is impregnated and cured with silicone rubber solution to form a dense protective barrier, thereby effectively blocking heat transfer. The thickness of the middle layer 3 is 0.1mm.

[0033] In this embodiment, the composite layer 4 is a mesh structure woven from aramid fibers. This material has excellent mechanical properties due to its unique three-dimensional mesh structure. Polyurethane resin is added to the aramid fibers. The upper surface layer 1, the lower surface layer 2, the middle layer 3 and the composite layer 4 are fixed by a hot pressing process.

[0034] Understandably, when the outside temperature rises, the PE film on the upper surface 1 comes into contact first. It can quickly react and reduce the rate at which heat is conducted inward. Then, the glass fiber inside exerts its heat insulation advantage, further reducing the impact of temperature fluctuations. The cotton and linen blend fabric that is closest to the skin is responsible for quickly wicking away moisture and keeping the skin dry. The reinforcing mesh that runs through the entire system enhances the system's ability to resist tearing damage.

[0035] In addition, a water-blocking layer is fixed on the upper surface of the middle layer 3. The water-blocking layer is a microporous PTFE film, which can both block rainwater and freely release water vapor, making the fabric breathable and rainproof.

[0036] The production steps of this high-temperature resistant coated textile fabric are as follows: prepare raw materials and cut them to the predetermined size. Place the cut PE film on top and lay it flat. Place the pre-treated fiberglass cloth and the pre-moistened PU foam sheet on the bottom. Then place a thin layer of cotton and linen fabric as a backing. The bottom layer is an impregnated aramid mesh curtain. After all layers are stacked, send them into a special hot press for shaping and processing. After the finished product is completely cooled, it can enter the packaging stage.

[0037] The design of the upper surface layer 1, lower surface layer 2, middle layer 3, and composite layer 4 greatly improves the adaptability of textile fabrics to high-temperature environments, enabling them to maintain their integrity in environments exceeding 200°C. This is significantly superior to similar competing products on the market. The scientific and reasonable layer distribution effectively balances the conflict between protection level and ventilation, giving the product a wider range of application potential. The adoption of a more environmentally friendly and sustainable production process reduces environmental pollution and lowers production costs.

[0038] Please see Figures 3 to 4 In order to operate continuously under extreme climatic conditions, the auxiliary cooling mechanism 5 in this embodiment includes a cloth bag 51 formed by hot pressing an upper surface layer 1, a lower surface layer 2, a middle layer 3 and a composite layer 4. Reinforcing ribs 52 are fixed at the four corners of the inner cavity of the cloth bag 51. The reinforcing ribs 52 can improve the strength of the cloth bag 51 and thus protect the service life of the cloth bag 51. A partition cloth 53 is sewn to the left end between the opposite sides of the inner top wall and the inner bottom wall of the cloth bag 51. A battery 54 is placed in the cavity formed on the left side of the cloth bag 51 and the partition cloth 53. A miniature fan 55 is fixed in the cavity formed on the right side of the cloth bag 51 and the partition cloth 53. The plug of the miniature fan 55 is connected to the battery 54, so that the battery 54 can provide power to the miniature fan 55. A fastening cloth 56 is sewn to the top of the front of the cloth bag 51. A first Velcro 57 is fixed to the lower surface of the fastening cloth 56 and a second Velcro 58 is fixed to the lower surface of the cloth bag 51, which can facilitate the replacement of the battery 54 and ensure the normal operation of the miniature fan 55 during use.

[0039] In this embodiment, the bag 51 is a cuboid with a hollow interior and a missing front side. The size of the fastening cloth 56 is larger than the size of the inner cavity at the notch on the front side of the bag 51. The size of the battery 54 is adapted to the size of the inner cavity formed by the bag 51 and the partition cloth 53 on the left side. The miniature fan 55 is electrically connected to the battery 54 through a wire.

[0040] It should be noted that the auxiliary cooling mechanism 5 can be used to generate forced convection for auxiliary cooling in particularly harsh working environments by means of an embedded micro fan 55 driven by electricity.

[0041] The working principle of the above embodiments is as follows:

[0042] (1) The upper layer 1 is made of high molecular weight polyethylene film with a thickness of 0.05 mm. It is mainly used to resist external high temperature attack. The high molecular weight polyethylene film has extremely high tensile strength and wear resistance. The lower layer 2 is made of cotton and linen blend material with a thickness of about 0.2 mm. It ensures the wearer's comfort while also absorbing moisture and sweat. The cotton and linen blend yarn ratio is 60% cotton and 40% linen. It is soft and has a good skin feel. The middle layer 3 is made of glass fiber mesh cloth as the base material with a thickness of about 0.1 mm. It is impregnated and cured with silicone rubber solution to form a dense protective barrier, thereby effectively blocking heat transfer. The composite layer 4 is made of aramid fiber woven into a mesh structure and reinforced with an appropriate amount of polyurethane resin. This material has excellent mechanical properties due to its unique three-dimensional mesh structure. When the external temperature rises, the PE film on the upper surface layer 1 comes into contact first. It can quickly react to reduce the rate of heat conduction inward. Then, the glass fiber set inside exerts its heat insulation advantage to further reduce the impact of temperature fluctuations. The cotton and linen blended fabric closest to the skin is responsible for quickly wicking away moisture and keeping the skin dry. The reinforcing mesh that runs through the entire system enhances the system's ability to resist tearing damage.

[0043] (2) The auxiliary cooling mechanism 5 can be set to provide forced convection cooling for particularly harsh working environments by means of the embedded miniature fan 55 and the electric drive of the fan blades. The reinforcing rib 52 can improve the strength of the cloth bag 51 and thus protect the service life of the cloth bag 51. When in use, the plug of the miniature fan 55 is connected to the battery 54 so that the battery 54 can provide power to the miniature fan 55. The fastening cloth 56, the first Velcro 57 and the second Velcro 58 can facilitate the replacement of the battery 54 and ensure that the miniature fan 55 operates normally during use.
