Description

Technical Field

[0001] This utility model relates to the field of fabric technology, specifically to a cold expansion fabric with autonomous temperature sensing function. Background Technology

[0002] Self-sensing temperature expansion fabric is a type of fabric that can thicken in low-temperature environments by utilizing the aerogel layer inside the fabric to shrink when it gets cold, thereby achieving a heat-insulating effect. In existing technologies, the aerogel layer of self-sensing temperature expansion fabric is bonded to other layers, making it difficult for air to circulate, thus resulting in less than ideal breathability of the fabric.

[0003] For example, patent publication number CN222610643U describes a cold-expanding fabric with self-sensing temperature function, comprising a support layer, an adhesive layer, an aerogel layer, a filling layer, and a protective layer arranged sequentially from the outside to the inside. Multiple aerogel layers are intermittently distributed between the adhesive layer and the filling layer. A connecting layer is located between two aerogel layers, also situated between the adhesive layer and the filling layer. By incorporating aerogel layers into the fabric, the fabric thickness is increased to enhance its thermal insulation performance by utilizing the aerogel's shrinkage upon cooling. This allows for adaptive adjustment based on the external environment, making it highly adaptable. However, this self-sensing cold-expanding fabric suffers from the problem that the aerogel layers adhere to other layers, hindering air circulation and resulting in insufficient breathability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a cold-expansion fabric with self-sensing temperature function, which solves the problem that the aerogel layer of the cold-expansion fabric with self-sensing temperature function is bonded to other layers, making it difficult for air to circulate and thus resulting in insufficient breathability of the fabric.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a cold expansion fabric with autonomous temperature sensing function, comprising a high-elastic bottom layer, a high-elastic top layer on top of the high-elastic bottom layer, an aerogel mechanism between the high-elastic bottom layer and the high-elastic top layer, and an adhesive layer between the high-elastic bottom layer, the high-elastic top layer and the aerogel mechanism.

[0006] The aerogel structure includes an aerogel layer with an air cavity inside. Support protrusions are fixedly connected to the top and bottom of the aerogel layer. Air permeable channels are left between the top and bottom of the aerogel layer and the high-elastic bottom and top layers. A sealing layer is fixedly connected to the top and bottom surfaces of the aerogel layer. Magnetic powder is added inside the sealing layer. Magnetic attraction areas are provided inside the high-elastic bottom and top layers. Air perforations are provided inside the magnetic attraction areas.

[0007] Preferably, both the high-elastic top layer and the high-elastic bottom layer are made of spandex material, which gives the high-elastic top layer and the high-elastic bottom layer excellent elasticity.

[0008] Preferably, the number of the support protrusions is set to four, and the support protrusions are integrally formed with the aerogel layer, so that the support protrusions and the aerogel layer can be mass-produced.

[0009] Preferably, the aerogel layer supports the high-elastic bottom layer and the high-elastic top layer through multiple supporting protrusions to form a breathable channel, and the breathable channel is connected to the breathable hole, so as to improve the breathability.

[0010] Preferably, the sealing layer is bonded to the aerogel layer, and the sealing layer is made of spandex material, so that the sealing layer can be used as a carrier of magnetic powder, and the sealing layer can deform synchronously with the deformation of the aerogel layer.

[0011] Preferably, the magnetic powder is added inside the magnetic attraction area, so that when the magnetic attraction area and the sealing layer are close together, they can be magnetically attracted to each other, thereby increasing the sealing effect.

[0012] Preferably, the high-elastic top layer includes a high-elastic layer, and the outer surface of the high-elastic layer is coated with an anti-ultraviolet coating. The anti-ultraviolet coating uses ultraviolet absorbers such as benzotriazole and benzophenone, which absorb ultraviolet energy through molecular structure and convert it into harmless heat energy or fluorescence, thus playing a good role in resisting ultraviolet rays.

[0013] This invention provides a cold-expansion fabric with autonomous temperature sensing function. Compared with the prior art, it has the following advantages:

[0014] 1. This cold-expansion fabric with self-sensing temperature function shrinks and thickens at low temperatures through an aerogel mechanism, and seals the pores to improve the heat preservation effect. It returns to its original shape at normal temperature, and the pores and ventilation channels are connected to improve breathability.

[0015] 2. This cold-expansion fabric with self-sensing temperature function uses ultraviolet absorbers such as benzotriazole and benzophenone in the anti-ultraviolet coating to absorb ultraviolet energy through molecular structure and convert it into harmless heat energy or fluorescence, thus playing a very good role in resisting ultraviolet rays.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 This utility model provides a technical solution: a cold expansion fabric with self-sensing temperature function, including a high-elastic bottom layer 1, a high-elastic top layer 3 on top of the high-elastic bottom layer 1, the high-elastic top layer 3 as the outer layer and the high-elastic bottom layer 1 as the inner layer, both the high-elastic top layer 3 and the high-elastic bottom layer 1 are made of spandex material, so that the high-elastic top layer 3 and the high-elastic bottom layer 1 have good elasticity, an aerogel mechanism 2 is provided between the high-elastic bottom layer 1 and the high-elastic top layer 3, and an adhesive layer 4 is provided between the high-elastic bottom layer 1 and the high-elastic top layer 3 and the aerogel mechanism 2, which can shrink and thicken the fabric at low temperature through the aerogel mechanism 2, and seal the vent holes 205 to improve the heat preservation effect, and return to its original shape at room temperature. The vent holes 205 are connected to the vent channels 202 to improve the breathability.

[0023] The aerogel structure 2 includes an aerogel layer 201 with an air cavity 203 inside. The air cavity 203 is filled with air and can play a role in heat insulation. Supporting protrusions 208 are fixedly connected to the top and bottom of the aerogel layer 201. The number of supporting protrusions 208 is set to four, and the supporting protrusions 208 are integrally formed with the aerogel layer 201, allowing for mass production of the supporting protrusions 208 and the aerogel layer 201. Breathable channels 202 are left between the top and bottom of the aerogel layer 201 and the high-elastic bottom layer 1 and the high-elastic top layer 3. The aerogel layer 201 supports the high-elastic bottom layer 1 and the high-elastic top layer 3 through the multiple supporting protrusions 208, forming the breathable channels 202. The breathable channels 202 are connected to the vents 205, improving breathability. A sealing layer 206 is fixedly connected to the bottom surface. Magnetic powder 207 is added inside the sealing layer 206. The sealing layer 206 is bonded to the aerogel layer 201 and is made of spandex material, allowing it to serve as a carrier for the magnetic powder 207. The magnetic powder 207 is mixed into the spandex fiber, facilitating its bonding with the sealing layer 206 and enabling the sealing layer 206 to deform synchronously with the aerogel layer 201. Both the high-elastic bottom layer 1 and the high-elastic top layer 3 have magnetic attraction areas 204 inside. The magnetic powder 207 is added inside the magnetic attraction areas 204, allowing them to magnetically attract each other when they are close to the sealing layer 206, increasing the sealing effect. Each magnetic attraction area 204 has ventilation holes 205 inside to increase air permeability.

[0024] Please see Figure 1 and Figure 4 The high-elastic top layer 3 includes a high-elastic layer 301. The outer surface of the high-elastic layer 301 is coated with an anti-ultraviolet coating 302. The anti-ultraviolet coating 302 uses ultraviolet absorbers such as benzotriazole and benzophenone. It absorbs ultraviolet energy through its molecular structure and converts it into harmless heat energy or fluorescence, thus playing a good role in resisting ultraviolet rays.

[0025] During operation, at low temperatures, the aerogel layer 201 contracts, causing the internal air cavity 203 to bulge. After the air cavity 203 bulges, it drives the upper and lower sealing layers 206 to approach the high-elastic bottom layer 1 and the high-elastic top layer 3 respectively. The sealing layer 206 uses the internal magnetic powder 207 to be attracted to the magnetic attraction area 204, so that the sealing layer 206 is in contact with the high-elastic bottom layer 1 and the high-elastic top layer 3. The sealing layer 206 blocks the vent 205, so that the vent 205 is disconnected from the vent channel 202, and the thickness of the entire fabric is increased, improving the heat preservation effect.

[0026] At room temperature, the aerogel layer 201 returns to its original state, causing the sealing layer 206 to separate from the high-elastic bottom layer 1 and the high-elastic top layer 3. The supporting protrusions on the aerogel layer 201 provide support for the high-elastic bottom layer 1 and the high-elastic top layer 3. The high-elastic bottom layer 1 and the high-elastic top layer 3 use their own elastic recovery principle to reform the breathable channel 202, allowing the breathable channel 202 to connect with the breathable hole 205, effectively improving the breathability.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
