Description

Technical Field

[0001] This application belongs to the field of fiber textile technology, specifically relating to a thermal fabric that can regulate body surface temperature based on humidity. Background Technology

[0002] In the field of functional textile materials, the balance between lightweight and warmth has always been a challenge. Traditional methods often improve insulation by increasing the number or thickness of fabric layers, but this inevitably leads to the fabric becoming heavy and stiff, thus reducing wearing comfort and skin feel.

[0003] Graphene fiber, due to its superior far-infrared receiving and emitting capabilities, has been widely used in thermal fabrics. It can resonate with the hydrogen-oxygen bonds in water molecules within the human body, efficiently converting absorbed radiant energy into molecular heat within biological tissues. This property not only enhances the material's warmth retention but also allows for a significant reduction in fabric thickness without sacrificing warmth, thereby increasing the lightness and comfort of clothing.

[0004] Patent application number 202321062206.8 discloses a self-heating fabric containing graphene fibers. The fabric structure comprises five functional layers arranged from the inside out: a contact layer, a heat transfer layer, a graphene layer, a thermal insulation layer, and a protective layer. This self-heating fabric not only utilizes the far-infrared function of the graphene layer to resonate with the human body, achieving internal heat circulation, but also uses the heat transfer layer to conduct the heat from the graphene layer to the skin surface, creating a combined internal and external heating effect. While improving warmth retention, it reduces the overall thickness of the fabric, enhancing its lightweight and comfort. However, this design has certain limitations in practical applications. Especially after the wearer sweats profusely, the sweat is absorbed by the contact layer and accumulates on the skin surface. At this time, the far-infrared radiation energy of the graphene layer is trapped by the large amount of sweat absorbed by the contact layer, thus reducing the overall heating effect of the fabric, and the wearer's perceived temperature drops significantly after exercise. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides a thermal insulation fabric, which is achieved through the following technical solution:

[0006] A thermal insulation fabric includes a sweat-absorbing layer, a far-infrared receiving and emitting layer, and a protective layer arranged sequentially; the far-infrared receiving and emitting layer contains graphene; the thermal insulation fabric further includes: a heat storage layer disposed between the sweat-absorbing layer and the far-infrared receiving and emitting layer, containing a plurality of heat storage chambers; a moisture-wicking interface including a moisture delivery end connected to the sweat-absorbing layer, a support section for forming the inner wall of the heat storage chamber, a far-infrared enhancement section connected to the far-infrared receiving and emitting layer, and water-absorbing and water-draining sections distributed on the outside of the protective layer; the moisture-wicking interface realizes bidirectional conduction of moisture between the sweat-absorbing layer and the outside of the protective layer based on its own capillary effect.

[0007] Preferably, the far-infrared enhancement section includes a dehumidification line for connecting to the absorbent and draining section, and an enhancement line with one end connected to the dehumidification line and the other end built into the far-infrared receiving and emitting layer and connected to the graphene.

[0008] Preferably, the number of synergistic lines on the side of the dehumidification line closer to the protective layer is greater than the number of synergistic lines on the other side of the dehumidification line.

[0009] Preferably, the heat storage chamber is also filled with a filling material.

[0010] Preferably, the heat storage chamber is further provided with a moisture-barrier membrane layer to prevent the filling material from getting wet.

[0011] Preferably, the heat storage chamber is also provided with a barrier layer to prevent the far-infrared receiving and emitting layer from coming into contact with the sweat absorbing layer.

[0012] Preferably, the barrier layer covers the surface of the support section.

[0013] Preferably, the thermal insulation fabric further includes a humidifying surface disposed on the surface of the protective layer, wherein the humidifying surface is connected to the moisture-wicking interface in a segmented manner for both absorption and drainage.

[0014] Compared with the prior art, this application has the following beneficial effects:

[0015] This application establishes a heat storage chamber between the sweat absorption layer and the far-infrared receiving and emitting layer. Through the design of the moisture-conducting interface and its location, after the body sweats, the sweat flows along the moisture transport end to the far-infrared enhancement section. The increased moisture in the far-infrared enhancement section causes the graphene material to heat up, enhancing its far-infrared emission function and strengthening the body's temperature sensation. Furthermore, the moisture in the far-infrared enhancement section flows to the absorption and drainage section under capillary action, evaporating on the outer layer of the protective layer. This reduces the interception of far-infrared emission energy caused by excessive moisture in the sweat absorption layer, collectively increasing the body's surface temperature.

[0016] This application increases the contact area between the moisture on the surface of the dehumidification line and the graphene by setting an enhancement line that is unidirectionally connected to the far-infrared enhancement section, thereby increasing the heating effect of the graphene material, enhancing the heat energy received by the graphene material, further increasing its far-infrared emission function, and raising the body surface temperature.

[0017] This application incorporates more synergistic lines on the side of the moisture-wicking line closest to the protective layer. When the external environment around the protective layer is humid and the skin is relatively dry, moisture is transported from the absorbent / drained section to the moisture-carrying end via capillary action at the moisture-wicking interface. During this process, more moisture is trapped in the far-infrared synergistic section by these synergistic lines, increasing the temperature of the graphene, enhancing its heat absorption, and thus increasing its far-infrared emission function. The sweat-absorbing layer absorbs less moisture, reducing the interception of far-infrared emission energy.

[0018] This application achieves heat preservation by designing a heat storage chamber that can store the temperature of graphene material after it heats up upon contact with water. Furthermore, by placing a filler inside and covering it with a moisture-barrier film layer, the temperature of the heat storage chamber can be further increased without blocking far-infrared emissions, thus enhancing the material's heat preservation effect.

[0019] This application avoids direct contact between the far-infrared emitting layer and the sweat-absorbing layer by placing a barrier layer between them and covering the surface of the support section, thus controlling the temperature rise caused by the graphene material contacting water. Furthermore, the stable heat storage chamber stores the temperature rise of the graphene material upon contact with water, achieving heat retention.

[0020] This application enhances the moisture absorption effect of the absorbent and draining segments outside the protective layer by setting a moisture-wicking interface on the surface of the protective layer and connecting it to the absorbent and draining segments. This also enhances the infrared emission enhancement effect of graphene in the far-infrared receiving and emitting layer. Furthermore, it provides a higher perceived temperature when the external humidity is high and the skin surface is relatively dry. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see the appendix Figures 1-3 This embodiment provides a thermal insulation fabric, including a sweat-absorbing layer 100 arranged sequentially for direct contact with the skin surface, made of wool; a heat storage layer 400 containing a plurality of heat storage chambers 410; a far-infrared receiving and emitting layer 200 made of graphene nylon; and a protective layer 300, the outermost layer of the thermal insulation fabric. Viewing along the protective layer 300 towards the sweat-absorbing layer 100, the heat storage chambers 410 are visible. Figure 2 The honeycomb structure shown is isolated. It is understood, of course, that in other embodiments, the heat storage chamber 410 may also present... Figure 3 The honeycomb pattern shown.

[0032] In this embodiment, the thermal insulation fabric further includes a moisture-wicking interface 500. One end of the moisture-wicking interface 500 is connected to the sweat-absorbing layer 100, and the other end sequentially passes through the heat storage layer 400, the far-infrared receiving and emitting layer 200, and the protective layer 300. Specifically, the moisture-wicking interface 500 includes a moisture delivery end 510 connected to the sweat-absorbing layer 100, a support section 520 for forming the inner wall of the heat storage chamber 410, a far-infrared enhancement section 530 connected to the far-infrared receiving and emitting layer 200, and water-absorbing and draining sections 540 distributed on the outside of the protective layer 300. The moisture-wicking interface 500 achieves bidirectional moisture conduction between the sweat-absorbing layer 100 and the outside of the protective layer 300 based on its own capillary effect.

[0033] To enhance the heat storage effect of the heat storage chamber 410, in this embodiment, a filler 411 is also provided inside the heat storage chamber 410. A moisture-barrier film layer 412 is also provided inside the heat storage chamber 410 to prevent the filler 411 from becoming wetted.

[0034] In this embodiment, during actual wear, when the body sweats, the sweat-absorbing layer 100 directly absorbs the sweat. Then, the moisture-wicking interface 500's moisture-transporting end 510, through capillary action, draws the sweat from the sweat-absorbing layer 100, which then flows sequentially through the support section 520 and the far-infrared enhancement section 530 to the water-absorbing section 540. The moisture in the water-absorbing section 540 dries under external conditions, reducing the moisture content of the sweat-absorbing layer 100. Furthermore, the moisture in the far-infrared enhancement section 530 comes into contact with the graphene in the far-infrared receiving and emitting layer 200, heating it up, increasing the graphene's far-infrared reception, enhancing its far-infrared emission, and increasing the perceived warmth on the skin.

[0035] Example 2

[0036] The difference between this embodiment and Embodiment 1 is that: firstly, looking along the protective layer 300 towards the sweat absorption layer 100, the heat storage chamber 410 presents... Figure 5The triangle shown. Secondly, no filler 411 and moisture-blocking membrane layer 412 are provided; however, in this embodiment, a barrier layer 600 is also provided on the heat storage chamber 410 to prevent the far-infrared receiving and emitting layer 200 from contacting the sweat absorbing layer 100. The barrier layer 600 covers the surface of the support section 520. Finally, to increase the far-infrared enhancement effect of graphene, the far-infrared enhancement section 530 in this embodiment includes a moisture-wicking line 531 for connecting to the water absorption and drainage section 540, and an enhancement line 532 with one end connected to the moisture-wicking line 531 and the other end built into the far-infrared receiving and emitting layer 200 and connected to the graphene. Furthermore, the thermal insulation fabric also includes a moisture-enhancing surface 700 disposed on the surface of the protective layer 300, and the moisture-enhancing surface 700 is connected to the water absorption and drainage section 540 of the moisture-wicking interface 500. Correspondingly, the amount of enhancement line 532 on the side of the dehumidification line 531 closest to the protective layer 300 is greater than the amount of enhancement line 532 on the other side of the dehumidification line 531.

[0037] In actual wear, when the body surface is dry and the outside is cold and damp, the absorbent section 540 will absorb the moisture captured by the moisturizing surface 700 and transport it to the moisture delivery end 510. When the moisture is transported to the far-infrared enhancement section 530, a large amount of moisture is trapped by the enhancement line 532 and sent to the far-infrared receiving and emitting layer 200. The graphene heats up when it comes into contact with water, increasing the far-infrared receiving amount of graphene and enhancing the far-infrared emitting amount of graphene, thereby increasing the body surface temperature sensation.
