Description

Technical Field

[0001] This invention belongs to the technical field of textile products, and specifically relates to temperature-regulating fabric.

Background Art

[0002] Conventional temperature-regulating fabrics mainly achieve temperature regulation through drug impregnation, surface coating, and post-finishing processes. However, the drug coating method has the following drawbacks. That is, the fabric has problems such as poor washability, poor texture, lack of breathability, and unstable temperature regulation effect during actual wearing and long-term use.

Summary of the Invention

[0003] The purpose of this invention is to provide a temperature-regulating fabric, which incorporates phase-change temperature-regulating microcapsules within the fabric fibers. By utilizing the phase-change principle of the phase-change temperature-regulating microcapsules to achieve intelligent temperature regulation, it solves problems such as insufficient washability, poor texture, poor breathability, and instability of the temperature regulation effect of temperature-regulating fabrics in the prior art. Thereby, it automatically adjusts the temperature according to the temperature difference between the human body and the environment, forms a stable constant-temperature microclimate near the comfortable temperature of the human body, and realizes a continuous comfort that is neither too hot nor too cold.

[0004] To achieve the above object, this invention adopts the following technical means.

[0005] This invention provides a temperature-regulating fabric including fiber yarns and formed by weaving the fiber yarns. Phase-change temperature-regulating microcapsules are provided within the fiber yarns. The phase-change temperature-regulating microcapsules include a capsule coating layer and an inner-layer phase-change heat storage core material, and the inner-layer phase-change heat storage core material is provided within the capsule coating layer.

[0006] When the temperature rises above a preset value, the inner-layer phase-change heat storage core material converts from a solid substance to a liquid substance.

[0007] Preferably, the capsule coating layer is a polymer coating layer.

[0008] Preferably, the phase-change temperature-controlled microcapsules are encapsulated inside the fiber yarn.

[0009] Preferably, the fiber yarn is a cotton fiber yarn.

[0010] Preferably, the fiber yarn is a synthetic fiber yarn.

[0011] Preferably, the chemical fiber yarn is nylon yarn, polyester yarn, rayon yarn, polyethylene yarn, polyurethane yarn, or acrylic yarn.

[0012] Preferably, the temperature-regulating fabric is formed by knitting or weaving the fiber yarn.

[0013] Preferably, the phase-change temperature-controlled microcapsule is spherical, ellipsoidal, cubic, or irregularly shaped.

[0014] Preferably, multiple phase-change temperature-controlled microcapsules are provided in the fiber yarn and are uniformly distributed.

[0015] Preferably, the temperature-regulating fabric is a pile fabric or a napped fabric.

[0016] By employing the above technical means, this invention has the following effects.

[0017] 1. The temperature-regulating fabric provided by this invention uses fibers as a carrier and incorporates phase-change temperature-regulating microcapsules within the fiber base material. As a result, the fabric itself has the ability to autonomously sense temperature. Consequently, the fabric automatically regulates its temperature in response to the temperature difference between the human body and the environment, forming a stable constant-temperature microclimate near the human body's comfortable temperature, achieving sustained comfort that is neither too hot nor too cold.

[0018] 2. The temperature-regulating fabric provided by this invention is highly breathable, less prone to stuffiness, and less likely to stick to the skin. Its internal fiber structure maintains openness, allowing for the normal release of moisture and sweat. This avoids the blockage of pores in the fabric, as can occur with coated fabrics. Furthermore, when body temperature is high, it absorbs heat to cool down while maintaining a dry and breathable state. As a result, stuffiness and sweat buildup are less likely to occur during exercise or sleep, providing a more natural wearing experience.

[0019] 3. In the temperature-regulating fabric provided by this invention, the phase change process of the inner phase-change heat-storage core material in the phase-change temperature-regulating microcapsule is a physical change, and the heat absorption-heat storage-heat release process can be carried out in a cyclical manner. Therefore, the temperature-regulating effect does not diminish with increasing use of the fabric, and thus its temperature-regulating function is stable and reversible, and can be used repeatedly over a long period of time. The fabric can be used throughout the four seasons, mitigating temperature differences in spring and autumn, being less stuffy in summer, and exhibiting higher heat retention in winter. Home textile products using this fabric can achieve comfortable performance throughout the four seasons.

[0020] 4. In the temperature-regulating fabric provided by this invention, the phase-change temperature-regulating microcapsules are not coated on the surface but are uniformly embedded within the fibers. In other words, the fibers themselves possess temperature-regulating elements, so they do not peel off or flake due to washing, friction, or exposure to sunlight. As a result, the temperature-regulating function of the fabric lasts for a longer period, is washable, and is less prone to functional degradation. Even after repeated machine washing, it maintains stable heat absorption and release capabilities. Its service life is almost identical to the lifespan of the fabric itself, achieving truly long-term, sustained temperature regulation.

[0021] 5. The temperature-regulating fabric provided by this invention achieves more uniform and stable temperature regulation. Because the phase-change temperature-regulating microcapsules are uniformly distributed within each fiber, the uniformity of temperature regulation throughout the fabric is high, and localized overheating or overcooling can be avoided. Its heat absorption and heat release response is more sensitive and more stable. As a result, a stable microclimate can be formed near the human body's comfortable temperature range.

[0022] 6. The temperature-regulating fabric provided by this invention is safe, environmentally friendly, odorless, and does not shed powder. The phase-change temperature-regulating microcapsules are completely sealed by a capsule coating layer formed of a polymer wall material, thus avoiding direct contact with the skin and preventing peeling, shedding, or migration of the coating. As a result, it does not release odors or harmful substances even at high temperatures or during perspiration. This allows it to meet safety standards for underwear and fabrics for infants.

[0023] 7. In the temperature-controlled fabric provided by this invention, the fibers containing phase-change temperature-controlled microcapsules can be woven into pile or napped fabrics, thereby promoting the industry's shift to a technology that directly adds phase-change temperature-controlled microcapsules during the fiber spinning stage, and developing the temperature-controlled function from surface-adhered to fiber-embedded. This maintains the flexible and comfortable properties of pile or napped fabrics while achieving continuous, uniform, and stable autonomous temperature control, making it truly suitable for long-term use of home textile products.

[0024] 8. The temperature-regulating fabric provided by this invention does not have a surface coating, and therefore fully retains the original feel of the fabric. Its texture is soft and does not impair the original texture of the pile or napped material. The pile maintains its bulkiness, breathability, and elasticity, while the napped material is flexible and smooth, not hardening or clumping. As a result, it feels good and comfortable against the skin even when worn directly, without any feeling of a film or foreign body. It is particularly suitable for loungewear, sleepwear, blankets, and infant products.

[0025] 9. The temperature-regulating fabric provided by the present invention has high compatibility with pile fabrics or fleece fabrics. Since the pile and fleece fabrics themselves are thick and three-dimensional, and have a rich air layer, the combination of the phase-change temperature-regulating microcapsules built into the fibers and the thick structure of the pile or fleece makes it easy to realize a double heat-insulating function and a dynamic temperature-regulating function. Thereby, heat is dissipated for heat preservation at low temperatures, and heat is absorbed to ensure breathability at high temperatures. Thereby, while maintaining the lightness and thinness of the fabric, an excellent constant temperature effect is realized, and the bulkiness and the feeling of stuffiness are eliminated.

All other embodiments that can be conceived by those skilled in the art based on the embodiments of the present invention without any special creative effort all belong to the protection scope of the present invention.

[0028] In this description of the present invention, the directions or positional relationships indicated by terms such as "up," "down," "front," and "back" are based on the directions or positional relationships shown in the drawings and are merely for the purpose of describing the present invention and simplifying the description.

The arrows in the figures indicate the direction of liquid flow. In this description of the present invention, unless otherwise explicitly specified or limited, terms such as "assembly," "installation," and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection. It may be a mechanical connection or an electrical connection. It may be a direct connection, an indirect connection via an intermediate mediator, or internal communication between two components. A person skilled in the art will be able to understand the specific meaning of the above terms in this invention depending on the specific situation.

[0029] The embodiments of this invention will be described in detail below with reference to the drawings.

[0030] Examples Referring to Figures 1 and 2, the temperature-regulating fabric according to this embodiment includes fiber yarn and is formed by knitting the fiber yarn 1.

[0031] A phase-change temperature-controlled microcapsule is provided within the fiber yarn 1, and the phase-change temperature-controlled microcapsule includes a capsule coating layer 201 and an inner layer phase-change heat storage core material 202, with the inner layer phase-change heat storage core material 202 provided within the capsule coating layer 201.

[0032] The inner phase-change heat storage core material 202 transforms from a solid substance 204 to a liquid substance 203 when its temperature rises above a preset value.

[0033] As shown in Figure 2, in the temperature-regulating fabric according to this embodiment, when the external ambient temperature rises or when excess heat is generated in the human body, the inner layer phase-change heat-storage core material 202 inside the phase-change temperature-regulating microcapsules in the fiber yarn 1 quickly absorbs the heat, converts from a solid substance 204 to a liquid substance 203 to store heat, suppresses a rapid rise in body surface temperature, and maintains the body in a cool and breathable state. When the ambient temperature drops and the human body feels cold, the inner layer phase-change heat-storage core material 202 returns from a liquid substance 203 to a solid substance 204, releasing the previously stored heat to continuously warm the human body and regulate the microclimate around the human skin, thereby maintaining the body surface at a temperature range close to the human body's comfortable range at all times. As a result, the phase-change temperature-regulating microcapsules act like a miniature smart air conditioner for the fabric, allowing the fabric to actively regulate the perceived temperature rather than passively responding to changes in temperature. Moreover, the entire process of heat absorption, heat storage, and heat release is a physically reversible process and can be carried out in a cyclical manner, which is advantageous for the fabric to maintain its temperature-regulating function over a long period of time.

[0034] Referring to Figures 1 and 2, specifically, the capsule coating layer 201 is a polymer coating layer. As shown in Figure 1, specifically, the phase-change temperature-controlled microcapsule is enclosed inside the fiber yarn 1.

[0035] Specifically, fiber yarn 1 is a cotton fiber yarn.

[0036] Specifically, fiber yarn 1 is a synthetic fiber yarn. Furthermore, the synthetic fiber yarn is nylon yarn, polyester yarn, rayon yarn, polyethylene yarn, polyurethane yarn, or acrylic yarn.

[0037] Specifically, the temperature-regulating fabric is formed by knitting or weaving fiber yarn 1.

[0038] Referring to Figures 1 and 2, specifically, the phase-change temperature-controlled microcapsules are spherical, ellipsoidal, cubic, or irregularly shaped.

[0039] Specifically, multiple phase-change temperature-controlled microcapsules are provided within the fiber yarn 1 and are uniformly distributed.

[0040] Specifically, the temperature-regulating fabric is either pile fabric or brushed fabric.

[0041] Finally, it should be noted that the embodiments described above are merely for illustrating the technical means of the present invention and do not limit the present invention. Although the present invention has been described in detail with reference to the embodiments described above, those skilled in the art should understand that further modifications can be made to the technical means described in each of the embodiments, or that some of their technical features can be substituted. These modifications or substitutions do not cause the essence of the corresponding technical means to deviate from the spirit and scope of the technical means relating to each embodiment of the present invention.
