Description

Technical Field

[0001] This utility model relates to the field of textile fabric technology, specifically to a self-heating insulating air layer fabric. Background Technology

[0002] Air-layer fabrics typically consist of a three-layer structure, including two outer layers and a relatively loose or air-filled air layer sandwiched between the two outer layers. The still air trapped in the air layer reduces heat transfer between the two outer layers, thus achieving a warming effect. In existing technologies, air layers can be formed through special textile processes or through multi-layer composite structures. The former produces a more seamless fabric, while the latter allows for the creation of different types of air layers by adjusting the structure of the middle layers, resulting in a wider range of product types.

[0003] Existing air-layer fabrics typically have a simple structure, consisting of only one layer of fabric. They lack a self-heating structure based on the temperature of human skin, resulting in limited functionality that fails to meet the diverse needs of today's consumers and hinders companies' market competitiveness. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a self-heating insulating air layer fabric.

[0005] The technical solution of this utility model is: a self-heating insulating air layer fabric, which is composed of a temperature response layer, a connecting layer and an insulating layer from bottom to top, bonded together by hot melt adhesive; the surface of the temperature response layer has several spaced structural layers, each structural layer consisting of multiple adjustment rails, double-layer fiber sensors that deform according to the temperature of the human body surface, and a button assembly disposed on one side of the surface of the temperature response layer for pulling each double-layer fiber sensor to slide within the adjustment rails. The adjustment rails are arranged parallel to each other on the surface of the temperature response layer, and the double-layer fiber sensors are disposed between every two adjacent adjustment rails. One side of the double-layer fiber sensor is connected to the adjustment rail through an elastic element, and the bottom of the double-layer fiber sensor is provided with a first friction plate that fits against the double-layer fiber sensor. A second friction plate is provided on the surface of the temperature response layer.

[0006] Furthermore, the two adjacent adjustment rails are staggered, and the double-layer fiber sensor has a parallelogram structure; Note: Conventional square and rectangular structures exhibit very small deformation during deformation, while parallelogram structures can significantly improve sensitivity.

[0007] Furthermore, the structural layer is woven from polyester warp yarns and Tencel weft yarns; Note: The above structure can effectively improve the overall tensile strength and breathability of the fabric.

[0008] Furthermore, each of the structural layers has at least two adjustment rails; Note: The above settings can further improve the friction self-heating efficiency by increasing the friction between the friction plate at the bottom of the adjustable track end point and the friction plate on the surface of the temperature response layer.

[0009] Furthermore, a polytetrafluoroethylene film is provided on the insulation layer; Note: Polytetrafluoroethylene film can make the surface fabric waterproof, breathable and downproof, and provide further insulation.

[0010] The beneficial effects of this utility model are: This invention utilizes an adjustable rail in the structural layer, a dual-layer fiber sensor that deforms according to the human body surface temperature, and a button to effectively adjust the structure of the first friction plate at the bottom of the dual-layer fiber sensor as the dual-layer fiber sensor expands and contracts. This adjusts the friction between the first friction plate and the second friction plate on the surface of the temperature-responsive layer. As the temperature rises, the deformation of the dual-layer fiber sensor reduces the contact area between the first and second friction plates, thus reducing friction. When the temperature decreases or remains constant, the friction between the first and second friction plates generates heat, better enabling the self-heating mechanism to be driven according to human body temperature.

Detailed Implementation

[0012] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0013] Example 1: As Figures 1-3 The self-heating insulating air layer fabric shown is composed of a temperature-responsive layer 1, a connecting layer 2, and an insulating layer 3, which are bonded together by hot melt adhesive from bottom to top. The surface of the temperature-responsive layer 1 has several spaced structural layers 11, including five horizontally spaced groups of structural layers 11. Each structural layer 11 consists of three adjustment rails 12, a double-layer fiber sensor 14 that deforms according to the temperature of the human skin, and a button assembly located on one side of the surface of the temperature-responsive layer 1 for sliding each double-layer fiber sensor 14 within the adjustment rails 12. The adjustment rails 12 are arranged parallel to each other on the surface of the temperature-responsive layer 1. The double-layer fiber sensor 14 is located between two adjacent adjustment rails 12. One side of the double-layer fiber sensor 14 is connected to the adjustment rail 12 via an elastic element, and the bottom of the double-layer fiber sensor 14 is provided with a connection to the double-layer fiber sensor. The sensor 14 is attached to a first friction pad 13, and a second friction pad 15 is provided on the surface of the temperature response layer 1. The elastic element is an elastic rope, which can be reset by the restoring force of the elastic rope after the double-layer fiber sensor 14 contracts. The first friction pad 13 is a thin film structure with a thickness of about 0.3 mm, which is laminated to the bottom of the fiber sensor 14 with a flexible adhesive. The first friction pad 13 is silicone rubber filled with 15% alumina to ensure that it is always in contact with the bottom of the double-layer fiber sensor 14. The second friction pad 15 is made of a hard material, such as nylon. The elastic element can reset the double-layer fiber sensor 14 after deformation for the next use, improving the practicality of the fabric. The bilayer fiber sensor 14 employs a previously disclosed technique of assembling a polymethyl methacrylate layer and a graphene layer together via dry spinning to create a reduced graphene oxide (rGO) / PMMA bilayer fiber thermal response sensor. By doping the graphene layer with TiO2 and TiN, the sensor can respond to light stimulation. The reduced graphene oxide (rGO) / PMMA bilayer fiber thermal response sensor prepared by chemically reducing graphene exhibits rapid response capabilities. When the relative temperature changes from 20°C to 50°C, the sensor's response time averages within 2 seconds, and the bidirectional curvature change rate of the fiber material can reach a maximum of 300%. As the temperature increases, the bilayer fiber structure bends towards the rGO side (the side with the smaller coefficient of thermal expansion). It should be noted that the button assembly consists of a button and a pull cord. The button is a pressure sensor that is woven or printed on the fabric. The pressure sensor 14 is electrically connected to the micro-drive module. One end of the pull cord is connected to the micro-drive module, and the other end is connected to each of the double-layer fiber sensors 14. The micro-drive module is a commercially available module used to pull the pull cord to make the double-layer fiber sensors 14 slide within the adjustment rail 12. It can be explained that, in this embodiment, the positional relationship between the reduced graphene oxide and PMMA is such that when the surface temperature of human skin rises, the opening of the double-layer fiber sensor 14 faces downward and does not contact or has little contact with the friction pad 13 on the surface of the temperature response layer 1. When the surface temperature of human skin remains unchanged or decreases, the double-layer fiber sensor 14 maintains its initial horizontal state and does not bend, so that friction can generate heat. The two adjacent adjustment rails 12 are staggered, and the double-layer fiber sensor 14 has a parallelogram structure. Specifically, the distance difference between the left and right ends of the two adjacent adjustment rails 12 is ±5cm. It can be understood that the arrangement is +5cm, -5cm, +5cm... The parallelogram structure enables the double-layer fiber sensor to better respond to changes in human body temperature. The structural layer is woven from polyester warp yarns and Tencel weft yarns; the weaving method is a three-dimensional crimp weaving method. The working principle of this embodiment is as follows: When the temperature rises, the double-layer fiber sensor 14 bends downwards, and the contact area with the bottom friction plate 13 decreases. When the temperature of the human skin surface remains unchanged or becomes cold, the double-layer fiber sensor 14 remains in its initial state. The drive button assembly pulls the double-layer fiber sensor 14 to slide in the adjustment rail 12. The first friction plate 13 at the bottom moves relative to the second friction plate 15 on the surface of the temperature response layer 1, which achieves the purpose of frictional heating.

[0014] Example 2: Unlike Example 1, which is not shown in the figure, the insulation layer 3 is provided with a polytetrafluoroethylene film; The working principle of this embodiment is basically the same as that of embodiment 1. The difference is that the polytetrafluoroethylene film can realize the waterproof, breathable and down-proof functions of the surface fabric, and play a further role in heat preservation.
