The elastic fiber layer 2 is fixedly connected to the outside of the tear-resistant base layer 1, the composite fireproof layer 3 is fixedly connected to the outside of the elastic fiber layer 2, and the antibacterial layer 4 is fixedly connected to the outside of the composite fireproof layer 3. The outer surface of the fabric body 5 is fixedly connected with elastic fiber lines 6 at equal intervals. The elastic fiber lines 6 are arranged in a wavy shape, and the elastic fiber lines are arranged as aramid fiber lines. The design of the elastic fiber lines 6 can further improve the overall tensile resistance and elasticity of the fabric, and also increase its surface friction, thereby improving the overall functionality of the fabric.

[0024] The composite fireproof layer 3 includes an elastic heat-insulating layer 31, which is fixedly connected to the outer side of the elastic fiber layer 2, and a flame-retardant fiber layer 32 is fixedly connected to the outer side of the elastic heat-insulating layer 31, and a heat-resistant fiber layer 33 is fixedly connected to the outer side of the flame-retardant fiber layer 32, and the outer side of the heat-resistant fiber layer 33 is fixedly connected to the inner side of the antibacterial layer 4, and the tear-resistant base layer 1 ensures the strong tear resistance of the fabric, making it not easy to be damaged during use and more durable; the elastic fiber layer 2 gives the fabric good elasticity and stretchability to ensure comfortable and free wearing or use, the elastic heat-insulating layer 31 in the composite fireproof layer 3 effectively insulates, the flame-retardant fiber layer 32 is excellent in flame retardancy, and the heat-resistant fiber layer 33 can withstand high temperatures, which jointly improve the fireproof and heat-resistant properties of the fabric, and the antibacterial layer 4 has a high-efficiency antibacterial effect, inhibiting the growth of bacteria, and each layer is tightly connected and synergistic. While having multiple functions such as fire prevention and antibacterial, it can also maintain good elasticity and adapt to various tensile deformations. It can be widely used in multiple fields and bring people a better use experience.

[0025] refer to Figure 1-Figure 3 The elastic fiber layer 2 is set as a polyester fiber layer, and the tear-resistant base layer 1 is set as an elastic aromatic polyamide fiber. The polyester fiber has good elasticity and resilience, which can make the fabric have good stretch performance, allowing the fabric to fit the body shape better and move freely during wearing or use. At the same time, the polyester fiber also has certain strength and wear resistance, which helps to improve the durability of the fabric.

[0026] refer to Figure 1-Figure 3 The heat-resistant fiber layer 33 is set as a polyimide fiber layer, and the flame-retardant fiber layer 32 is set as a ceramic fiber layer. The polyimide fiber has very high heat resistance and can remain stable in a high temperature environment, so that the fabric is not easily damaged or deformed when facing high temperature conditions, which broadens the use range of the fabric. It also has good mechanical properties and enhances the strength and durability of the fabric. There is also a significant advantage in setting the flame-retardant fiber layer 32 as a ceramic fiber layer. Ceramic fiber has excellent flame retardant effect and can effectively prevent the spread of fire when encountering a fire source, thereby improving the fire safety of the fabric. Moreover, ceramic fiber also has good chemical stability and corrosion resistance, which further improves the overall performance and quality of the fabric. The combination of the two makes the fabric perform better in heat resistance and flame retardancy, ensuring the safety and reliability of use.

[0027] refer to Figure 1-Figure 3The elastic thermal insulation layer 31 is set as a superelastic cellulose aerogel layer, and the thickness of the elastic thermal insulation layer 31 is 0.13cm-0.17cm. The superelastic cellulose aerogel layer has excellent elasticity and recoverability, can maintain the stability of the structure under large strain, and can quickly return to its original state after unloading. This enables the fabric to better adapt to the movement and deformation of the human body during use, providing a comfortable wearing experience. The aerogel has extremely low thermal conductivity and can effectively prevent the transfer of heat. The thermal insulation performance of the superelastic cellulose aerogel layer can help reduce heat loss and improve the thermal insulation performance of the fabric. Cellulose is a natural polymer material with the characteristics of being renewable and biodegradable. The use of a superelastic cellulose aerogel layer as the elastic thermal insulation layer 31 is in line with the concept of environmentally friendly and sustainable development. The thickness of the elastic thermal insulation layer 31 is between 0.13cm-0.17cm. This thickness range can provide good thermal insulation performance while maintaining the softness and breathability of the fabric. A thinner thickness can reduce the weight and thickness of the fabric and increase the comfort of wearing; while a thicker thickness can provide better thermal insulation effect, which is suitable for occasions with high requirements for warmth.

[0028] refer to Figure 2-Figure 4 The antibacterial layer 4 includes a first antibacterial layer 41, which is fixedly connected to the outside of the heat-resistant fiber layer 33, and a second antibacterial layer 42 is fixedly connected to the outside of the first antibacterial layer 41, and a third antibacterial layer 43 is fixedly connected to the outside of the second antibacterial layer 42. The first antibacterial layer 41 is set as a silver ion antibacterial layer, the second antibacterial layer 42 is set as a copper ion fiber spandex blended layer, and the third antibacterial layer 43 is set as a spandex light yarn layer, which is specifically a bamboo charcoal fiber and spandex blended layer, and the thickness of the spandex light yarn layer is 0.10cm-0.12cm. The silver ion antibacterial layer of the first antibacterial layer 41 has a high-efficiency antibacterial effect, can strongly inhibit the growth of bacteria, and protect the health of users. The copper ion fiber spandex blended layer of the second antibacterial layer 42 further enhances the antibacterial performance, and synergizes with the first antibacterial layer 41 to enhance the overall antibacterial effect. The bamboo charcoal fiber and spandex blended layer of the third antibacterial layer 43 increases the texture of the fabric while maintaining good antibacterial properties. The thickness of the spandex yarn layer is between 0.10cm and 0.12cm, which can ensure a certain antibacterial function without making the fabric too heavy, maintaining a certain lightness and breathability. Such an antibacterial layer 4 has a reasonable structure and excellent antibacterial performance, can provide users with a safe and comfortable use experience, and can play a good role in different scenarios.

[0029] Usage principle and advantages: The tear-resistant base layer 1 adopts elastic aromatic polyamide fiber, which ensures that the fabric has extremely strong tear resistance and elasticity, making it not easy to be damaged during use, more durable and tough. The elastic fiber layer 2 is set as a polyester fiber layer, which gives the fabric good elasticity and allows the fabric to rebound quickly after stretching, ensuring comfort and freedom when wearing or using. The elastic insulation layer 31 in the composite fireproof layer 3 is a super elastic cellulose aerogel layer, which plays a good insulation role and can effectively block heat transfer; the ceramic fiber layer of the flame retardant fiber layer 32 has excellent flame retardant properties and can prevent the spread of fire when encountering open flames. The polyimide fiber layer of the heat-resistant fiber layer 33 can withstand higher temperatures, further improving the fireproof and heat-resistant capabilities of the fabric. At the same time, the above materials are all elastic materials and can maintain good elastic properties. The first antibacterial layer 41 of the antibacterial layer 4, namely the silver ion antibacterial layer, has a high antibacterial effect and can effectively inhibit the growth of bacteria. The copper ion fiber spandex blended layer of the second antibacterial layer 42 enhances the antibacterial properties. The bamboo charcoal fiber and spandex blended layer of the third antibacterial layer 43 increases the texture of the fabric while maintaining the antibacterial properties. The elastic advantage of the entire fabric mainly comes from the reasonable matching and synergy between the elastic fiber layer 2 and the various layer structures. The polyester fiber The elasticity of the layer enables the fabric to adapt to different stretching and deformation requirements. At the same time, the other layer structures, on the basis of ensuring their own functions, also work closely with the elastic fiber layer 2 to ensure the excellent elastic performance of the fabric, so that users can feel comfortable and at ease in daily activities or special environments. In short, this high-elastic knitted fabric has great application value and advantages in many fields due to the unique role of its various layer structures and excellent elasticity. The elastic fiber layer 2 is set as a polyester fiber layer. Polyester fiber has good elasticity and stretchability, which can provide basic elasticity guarantee for the fabric. Secondly, the tear-resistant base layer 1 adopts The elastic aromatic polyamide fiber also has a certain elasticity, and cooperates with the elastic fiber layer 2 to further enhance the elastic properties of the fabric. Furthermore, the layers are tightly combined through fixed connections, which ensures their respective functions while also working synergistically. The fabric has multiple properties such as fire prevention and antibacterial, while the overall structure can still adapt to stretching and deformation, thereby ensuring good elasticity. For example, although the elastic thermal insulation layer 31 in the composite fireproof layer 3 mainly plays a thermal insulation role, it also has a certain elasticity and will not hinder the elastic performance of the fabric. The same is true for the antibacterial layer 4. Each antibacterial layer can adapt to the elastic changes of the fabric while playing an antibacterial role.
