Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fabric, especially a novel fabric. BACKGROUND

[0002] Protective clothing in high-risk industries such as fire fighting and chemical industry is an important equipment to protect the safety of workers, especially in extreme working environments such as fire, high temperature, and chemical leakage. The existing protective clothing fabric mostly has the problem of single protection function. For example, although the existing fireproof clothing can prevent flame invasion, it lacks effective heat insulation function; and the fabric that prevents chemical leakage cannot consider other protection needs such as fireproof and heatproof. In addition, the existing protective clothing fabric often ignores the comfort of wearing when providing protection performance, which leads to discomfort of the wearer when working for a long time due to high temperature, poor air permeability, and other problems, and in severe cases, it will also affect work efficiency and health.

[0003] In addition, the existing protective clothing mostly uses single material, and the interlayer connection stability of the fabric is poor. In high temperature, strong chemical exposure or high pressure environment, the different functional layers are prone to falling off, separation and other problems, thereby affecting the overall protection effect. Therefore, the durability and structural stability of the existing protective clothing are insufficient, which cannot meet the requirements of long-term and high-intensity use in special industries. At the same time, the existing fabric lacks comprehensive protection capability and cannot meet the multiple protection requirements of fireproof, chemical penetration prevention, and antistatic, which leads to the fact that it cannot provide all-round protection in complex working environment.

[0004] Therefore, the present application provides a novel fabric. CONTENT OF THE UTILITY MODEL

[0005] The purpose of the present application is to provide a novel fabric, which at least solves the problem of insufficient functionality of the existing protective clothing fabric, and the deficiencies in comfort, interlayer connection stability and durability.

[0006] To solve the above technical problems, the utility model provides the following technical scheme:

[0007] The present application provides a novel fabric, which comprises an outermost fireproof layer, a second layer of heat insulation layer hot-pressed on the fireproof layer, a chemical penetration prevention layer connected to the heat insulation layer, an inner layer sewn to the chemical penetration prevention layer, and an antistatic layer fixedly connected to the inner layer. The heat insulation layer is connected to the chemical penetration prevention layer by an adhesive, and the inner layer is connected to the antistatic layer by conductive fibers.

[0010] In a further aspect, the thermal barrier layer comprises one of aerogel, a silica gel coating, or a fiberglass material layer.

[0011] In a further aspect, the thermal barrier layer has a thickness of 0.3 mm to 1.5 mm.

[0012] In a further aspect, the chemical resistant layer comprises one of a polyurethane coating, a fluorinated polymer coating, or a polyethylene film layer.

[0014] In a further aspect, the inner layer comprises one of a polyester layer or a cotton fiber layer.

[0015] In a further aspect, the inner layer has a thickness of 0.1 mm to 0.5 mm.

[0016] In a further aspect, the adhesive comprises one of an epoxy resin glue, a phenol formaldehyde resin glue, or a polyurethane glue.

[0017] The utility model has the following beneficial effects compared with the prior art:

[0018] By effectively integrating multiple functions such as fireproofing, thermal insulation, chemical resistance, and anti-static, a comprehensive protection solution is provided. By using excellent fireproof materials such as aramid fiber or carbon fiber, thermal insulation materials such as aerogel or silica gel, and chemical resistant materials such as polyurethane or fluorinated polymer, and connecting the anti-static layer through conductive fibers, the fabric can provide comprehensive safety protection for the wearer in extreme working environments such as high temperature, fire, and chemical leakage. The connection between the layers through efficient heat pressing, adhesive, and stitching process ensures the stability and comfort of the fabric. The thickness design of different layers is reasonable, which can ensure the protection performance without affecting the freedom and comfort of the wearer. The fabric is widely used in high-risk industries such as fire fighting and chemical industry, which can effectively improve the safety, comfort, and work efficiency of the wearer.

[0025] In order to make the technical problems, technical solutions and beneficial effects of the utility model clearer and more understandable, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and do not limit the utility model.

[0026] The application provides a novel multi-layer composite fabric suitable for protective clothing in high-risk industries such as firefighting and chemical industry. The fabric effectively integrates various protective functions such as fireproofing, thermal insulation, chemical permeation resistance, and antistatic properties through multi-layer structure design, thereby providing comprehensive protection for wearers in extreme working environments.

[0027] As shown in Figure 1 The multi-layer composite fabric of the application is composed of five main layers, including the outer fireproof layer 1, thermal insulation layer 2, chemical resistant layer 3, inner layer 4, and antistatic layer 5. The selection and thickness design of each layer of material are targeted at specific functional requirements, and different connection processes are used to ensure the overall stability and functionality of the fabric.

[0028] The outermost layer of the fabric is the fireproof layer 1, which mainly uses materials such as aramid fiber or carbon fiber with excellent fireproof performance. Aramid fiber (such as Kevlar) and carbon fiber not only have high strength and high temperature resistance, but also can effectively prevent the invasion of fire and heat, thereby protecting the wearer from the threat of fire. The thickness of the fireproof layer 1 ranges from 0.5 mm to 2 mm, which can ensure sufficient fireproof performance while avoiding the rigidity and discomfort caused by excessive thickness.

[0029] Under the fireproof layer 1 is the thermal insulation layer 2, which is mainly used to prevent high-temperature conduction and ensure that the wearer is not burned in a high-temperature environment. The thermal insulation layer 2 usually uses aerogel, silicone coating, or glass fiber materials, which have very low thermal conductivity and can effectively block heat conduction to the inner layer 4. Aerogel, as a thermal insulation material, has excellent thermal insulation effect and light weight, which can provide extremely high thermal insulation performance while ensuring comfort. The thickness of this layer is 0.3 mm to 1.5 mm to ensure good thermal insulation effect and avoid excessive weight of the overall fabric.

[0030] The chemical-resistant layer 3 is below the thermal insulation layer 2, which is used to prevent the penetration of harmful chemicals. The chemical-resistant layer 3 uses impermeable materials such as polyurethane coating, fluorinated polymer coating, or polyethylene film, which can effectively prevent the penetration of chemicals such as acids, bases, and organic solvents, thereby protecting the wearer's safety in a chemical leakage environment. The thickness of this layer is usually 0.2 to 1 millimeters, and the thickness is relatively thin to maintain the flexibility of the fabric while achieving sufficient chemical protection effect.

[0031] The inner layer 4 is mainly used to provide comfort, which can use materials such as polyester fiber or cotton fiber. Polyester fiber has good air permeability and moisture absorption, which can keep the skin dry and reduce the discomfort when wearing. Cotton fiber is suitable for long-term contact with the skin due to its natural softness and comfort. The thickness of the inner layer 4 is usually 0.1 to 0.5 millimeters to ensure the comfort of the wearer during long-term wear, and will not cause a stuffy feeling due to excessive thickness.

[0032] As shown in Figure 2 The antistatic layer 5 is located below the inner layer 4, usually connected with the inner layer 4 through conductive fibers 7 such as carbon fibers. The role of the antistatic layer 5 is to prevent static electricity accumulation, thereby avoiding sparks or explosions caused by static electricity. Especially in the environment of handling flammable substances, the elimination of static electricity is crucial. The thickness of the antistatic layer 5 is generally between 0.05 and 0.3 millimeters, which can effectively conduct electricity without affecting the flexibility of the fabric.

[0033] In terms of connection between layers, different connection settings are adopted to ensure that each layer of the fabric has sufficient bonding strength and durability, while maintaining the overall flexibility and comfort of the fabric.

[0034] The fireproof layer 1 and the thermal insulation layer 2 are connected by hot pressing process. This connection method can make the two layers tightly combined without affecting the performance of the fireproof layer 1, providing better stability and anti-peeling. Hot pressing process combines the two layers of materials firmly through high temperature and pressure, ensuring reliability in high temperature environment.

[0035] The thermal insulation layer 2 and the chemical-resistant layer 3 are connected by high-temperature adhesive 6, usually using epoxy resin adhesive or polyurethane adhesive, etc. These adhesives 6 have strong adhesion and can maintain stable performance in high temperature and chemical environment, preventing interlayer separation.

[0036] The connection between the chemical-resistant layer 3 and the inner layer 4 uses a stitching setting to avoid using too much chemical adhesive 6, thereby maintaining the air permeability and comfort of the inner layer 4. The stitching process ensures the firm connection between the layers, while not affecting the function of the inner layer 4.

[0037] The inner layer 4 is connected to the antistatic layer 5 via conductive fibers 7. The conductive fibers 7 create effective current channels within the fabric, preventing static electricity buildup. The selection of conductive fibers 7 ensures the electrical conductivity of the antistatic layer 5 while also guaranteeing its stability and comfort.

[0038] like Figure 2 As shown, the adhesive 6 used in the bonding between layers is selected based on the properties of the materials and the application environment. Specifically, the adhesives 6 used include epoxy resin adhesives, polyurethane adhesives, and phenolic resin adhesives. These adhesives 6 exhibit excellent bonding performance in environments with high temperature, humidity, and chemical contact, ensuring the long-term use of multilayer composite fabrics in extreme environments.

[0039] Multi-layer composite fabrics have broad application prospects. Especially in protective clothing for industries such as firefighting, chemical engineering, military, and aerospace, this fabric effectively blocks flames, provides heat insulation, prevents chemical penetration, and eliminates static electricity, offering comprehensive protection for workers. Furthermore, the fabric's excellent comfort and flexibility allow wearers a high degree of freedom of movement during tasks, improving work efficiency.

[0040] In summary, through the aforementioned multi-layer composite structure design and meticulous interlayer connection, the fabric of this application not only possesses multiple functions such as fire resistance, heat insulation, chemical penetration resistance, and antistatic properties, but also ensures the fabric's comfort and durability. These innovative technical solutions enable this fabric to provide effective protection in complex, high-risk working environments, and it has broad application potential.

[0041] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
