[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a puncture-proof fabric with heat preservation performance, comprising a skin-friendly layer 1, a heat-insulating layer 2 and a puncture-proof layer 3. The puncture-proof fabric is composited by the skin-friendly layer 1, the heat-insulating layer 2 and the puncture-proof layer 3. The skin-friendly layer 1 is arranged on the bottom surface of the heat-insulating layer 2. The skin-friendly layer 1 is the innermost layer and directly contacts the skin. The material of the skin-friendly layer 1 is bamboo fiber, which ensures the comfort and skin health of the wearer. The heat-insulating layer 2 is located between the skin-friendly layer 1 and the puncture-proof layer 3, and its main function is heat insulation and warmth preservation. A waterproof and breathable membrane 11 is arranged between the skin-friendly layer 1 and the heat-insulating layer 2. The waterproof and breathable membrane 11 is between the skin-friendly layer 1 and the heat-insulating layer 2. Its function is to prevent external moisture from penetrating into the inner layer, while allowing water vapor discharged from the body to pass through, so as to keep dry and maintain breathability. The puncture-proof layer 3 is arranged on the surface of the heat-insulating layer 2. The puncture-proof layer 3 is used to provide physical protection to prevent sharp objects or other sharp objects from penetrating the fabric and causing injury.

[0028] Reference Figure 1 - Figure 3 The thermal insulation layer 2 includes a plurality of parallel thermal insulation fibers 21, which are connected in a mesh-like manner by connecting fibers 22. The thermal insulation fibers 21 are aerogel fibers, and the connecting fibers 22 are polyester fibers. Aerogel fibers are known for their extremely low thermal conductivity, which means that they can effectively prevent heat from being lost through the fibers, thereby maintaining temperature, while polyester fibers provide structural strength and durability, so that the thermal insulation layer 2 can maintain its shape and function even under frequent use or extreme conditions. A honeycomb micro-nanoporous layer 23 is provided on the bottom surface of the thermal insulation fibers 21 and the connecting fibers 22. The micro-nanoporous chambers of the honeycomb structure can capture air, further preventing heat from passing through, while also enhancing the overall air permeability of the material to prevent the wearer from feeling stuffy. A floating yarn layer 24 is provided on the bottom surface of the honeycomb micro-nanoporous layer 23, and down 25 is provided on the bottom surface of the floating yarn layer 24. The floating yarn layer 24 is used to increase the softness and air permeability of the overall fabric, and the down 25 provides additional warmth retention.

[0029] Reference Figure 1 - Figure 2The puncture-proof layer 3 includes high-tenacity fibers and puncture-proof fibers, which are woven with seamless technology. The high-tenacity fibers and puncture-proof fibers provide protection against sharp objects and have high puncture resistance. The surface of the puncture-proof layer 3 is coated with a waterproof coating 31, which not only enhances the waterproofness of the fabric, but also helps resist external liquid pollution, so that the fabric can remain dry and comfortable in a variety of environments.

[0030] Working principle: When the wearer puts on clothing made of this fabric, the first thing he feels is the softness and comfort of the skin-friendly layer 1. The presence of the waterproof and breathable membrane 11 effectively prevents external moisture from entering, while allowing moisture in the body to be discharged, thereby ensuring that the clothing is dry and breathable. Next, the thermal insulation layer 2 begins to play its key role. The thermal insulation fiber 21 composed of aerogel fibers effectively reduces heat loss with its low thermal conductivity. At the same time, the connecting fiber 22 of polyester fibers ensures the structural strength and durability of the entire thermal insulation layer 2. The addition of the honeycomb micro-nanoporous layer 23 further enhances the thermal insulation effect by capturing air, and also helps to maintain the breathability of the fabric. The superposition of the floating yarn layer 24 and the down 25 further enhances the overall thermal insulation performance, allowing the wearer to feel warm and comfortable even in a cold environment.

[0031] The puncture-proof layer 3 provides physical protection for the wearer. The seamless weaving of high-tenacity fibers and puncture-proof fibers makes the fabric highly resistant to puncture and can effectively resist the invasion of sharp objects. The addition of the waterproof coating 31 not only enhances the waterproof performance of the fabric, but also makes it easier to clean and maintain.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
