Description

Technical Field

[0001] This utility model relates to the field of fabric technology, and in particular to a textile fiber fabric. Background Technology

[0002] Carbon fiber cloth, also known as carbon fiber cloth or carbon fiber cloth, plays an important role in the field of reinforcement. It is a commonly used reinforcement material that can be applied to the reinforcement and repair of various materials such as building structures, bridges, pipelines, ships, and concrete. Specifically, it is a cloth woven from carbon fiber yarns. Carbon fiber is a fibrous material composed of carbon elements, which has the characteristics of high strength, high modulus, and low density.

[0003] Currently used carbon fiber cloth has poor fire resistance during use, making it easy to burn or melt in the event of a fire. It cannot effectively prevent the spread of fire, resulting in a faster and more difficult-to-control fire. In high-temperature environments, carbon fiber cloth with poor fire resistance can also experience thermal instability, leading to a reduction in its strength and stiffness. This makes the load-bearing structure unable to withstand the design load, thus causing the risk of structural damage or collapse. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a textile fiber cloth.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a textile fiber cloth, including a fiber cloth base layer, wherein the fiber cloth base layer is woven from high temperature resistant composite fibers, and a polyimide film is provided on both sides of the fiber cloth base layer.

[0006] By adopting the above technical solutions, the composite fiber has good high temperature resistance, enabling the fiber cloth base layer to work continuously in high temperature environments. The polyimide film has good chemical corrosion resistance, electrical insulation, high temperature resistance, and good mechanical properties. The polyimide film is chemically stable and can prevent combustion without the addition of flame retardants. This gives the textile fiber cloth good high temperature resistance, chemical corrosion resistance, and flame retardant properties, reducing the probability that the carbon fiber cloth will rapidly destabilize due to heat in the event of a fire.

[0007] Furthermore, the composite fiber comprises carbon fibers and polypropylene fibers twisted together.

[0008] By adopting the above technical solutions, carbon fiber possesses properties such as high temperature resistance, wear resistance, corrosion resistance, and tensile strength, and can withstand temperatures up to 2000℃. Polypropylene fiber has excellent properties such as lightweight, wear resistance, antibacterial properties, crack resistance, impermeability, and abrasion resistance. Carbon fiber and polypropylene fiber are twisted together to form composite fibers, which are then used to weave fiber cloth, giving the fiber cloth excellent properties such as high temperature resistance, wear resistance, corrosion resistance, tensile strength, antibacterial properties, crack resistance, and impermeability.

[0009] Furthermore, the composite fiber also includes aramid fiber, which is twisted together with carbon fiber and polypropylene fiber to form the composite fiber.

[0010] By adopting the above technical solutions, aramid fibers have excellent properties such as high strength, high modulus, high temperature resistance, light weight, and flame retardancy. The long-term service temperature of aramid fibers can reach 204℃, and the instantaneous temperature resistance can reach 240℃. The addition of aramid fibers enhances the strength, high temperature resistance, and flame retardancy of the fiber cloth.

[0011] Furthermore, the composite fiber also includes glass fiber, which is twisted together with carbon fiber, polypropylene fiber and aramid fiber to form the composite fiber.

[0012] By adopting the above technical solutions, glass fiber has excellent properties such as strong heat resistance, good corrosion resistance, and high mechanical strength. Glass fiber has excellent stability at high temperatures and can maintain the basic stability of its physical and chemical properties in a high-temperature environment of 250℃. The addition of glass fiber enhances the mechanical strength and corrosion resistance of the fiber cloth.

[0013] Furthermore, the fiber cloth base layer and the polyimide film are bonded together by an adhesive layer.

[0014] Furthermore, the fiber cloth base layer and the polyimide film are stitched together with a suture thread.

[0015] Furthermore, the suture is a thread made of multiple twisted glass fibers.

[0016] Furthermore, each side of the fiber cloth base layer has two stitches, located near the edge of the fiber cloth base layer.

[0017] By adopting the above technical solution, the stability of the connection between the fiber cloth base layer and the polyimide film is ensured.

[0018] Furthermore, the bottom surface of the polyimide film is uniformly coated with a fire-retardant coating layer.

[0019] By adopting the above technical solutions, the flame retardant properties of textile fiber fabrics have been further enhanced.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. In this application, the composite fiber has good high temperature resistance, which enables the fiber cloth base layer to work continuously in a high temperature environment. The polyimide film has good chemical corrosion resistance, electrical insulation, high temperature resistance and good mechanical properties. The polyimide film has stable chemical properties and can prevent combustion without adding flame retardants. Thus, the textile fiber cloth has good high temperature resistance, chemical corrosion resistance and flame retardant properties.

[0022] 2. In this application, polypropylene fiber has excellent properties such as light weight, wear resistance, antibacterial properties, crack resistance, seepage prevention, and abrasion resistance. Carbon fiber and polypropylene fiber are twisted together to form composite fiber, which is used to textile fiber cloth, so that the fiber cloth has excellent properties such as high temperature resistance, wear resistance, corrosion resistance, tensile strength, antibacterial properties, crack resistance, and seepage prevention.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] Example 1

[0031] like Figure 1-5As shown in the embodiment of this application, a textile fiber cloth is disclosed, including a fiber cloth base layer 1, which is woven from high temperature resistant composite fibers 2, and polyimide films 3 are provided on both sides of the fiber cloth base layer 1.

[0032] Composite fiber 2 possesses excellent high-temperature resistance, enabling the fiber cloth base layer 1 to operate continuously in high-temperature environments. Polyimide film 3 exhibits good chemical resistance, electrical insulation, high-temperature resistance, and good mechanical properties (in existing technology, the Upilex S film in polyimide film 3 can withstand temperatures above 500℃). Polyimide film 3 is chemically stable and can prevent combustion without the addition of flame retardants. This gives the textile fiber cloth good high-temperature resistance, chemical resistance, and flame retardancy, reducing the probability of rapid instability of carbon fiber 21 cloth due to heat in the event of a fire. Carbon fiber 21 possesses high-temperature resistance, wear resistance, corrosion resistance, and tensile strength, and can withstand temperatures up to 2000℃.

[0033] The composite fiber 2 comprises carbon fiber 21, polypropylene fiber 22, aramid fiber 23, and glass fiber 24 twisted together. Carbon fiber 21 possesses properties such as high temperature resistance, wear resistance, corrosion resistance, and tensile strength. Polypropylene fiber 22 exhibits excellent properties such as lightweight, wear resistance, antibacterial properties, crack resistance, impermeability, and abrasion resistance. Aramid fiber 23 possesses excellent properties such as high strength, high modulus, high temperature resistance, light weight, and flame retardancy. Glass fiber 24 possesses excellent properties such as strong heat resistance, good corrosion resistance, and high mechanical strength. The composite fiber 2, formed by twisting carbon fiber 21, polypropylene fiber 22, aramid fiber 23, and glass fiber 24 together, is used to weave fiber cloth, giving the fiber cloth excellent properties such as high temperature resistance, wear resistance, corrosion resistance, tensile strength, antibacterial properties, crack resistance, impermeability, and flame retardancy.

[0034] In this embodiment, the fiber cloth base layer 1 and the polyimide film 3 are bonded together by an adhesive layer 4. The bottom surface of the polyimide film 3 is uniformly coated with a fire-retardant coating layer 31. When using textile fiber cloth for reinforcement, the fire-retardant coating layer 31 is located on the side away from the object being reinforced.

[0036] like Figure 1-4 As shown, the difference between this embodiment and embodiment 1 is only that: in order to enhance the connection stability between the layers of the textile fiber cloth, the fiber cloth base layer 1 and the polyimide film 3 are connected by stitching thread 5. The stitching thread 5 is a thread made of multiple glass fibers twisted together. There are two stitching threads 5 on each side of the fiber cloth base layer 1, and they are located near the edge of the fiber cloth base layer 1.
