[0002] A temperature-sensitive color-changing fabric is a fabric that can change its color with the change of temperature. Its principle is based on temperature-sensitive dyes or pigments contained in the material. These dyes or pigments will change their molecular structures with the increase or decrease of temperature, thus causing color changes. When this fabric is applied in daily life, it can change color according to the body temperature, increasing the interest and sense of technology.
[0003] Currently, for temperature-sensitive color-changing fabrics, the temperature-sensitive color-changing materials are first made into filaments, and through the mixing of these filaments with fabric textile filaments, they are woven by a loom; when the above-mentioned existing temperature-sensitive color-changing fabrics are in use, the temperature-sensitive color-changing fabrics will have problems such as uneven changes or difficult-to-control color change rates, thus affecting the use effect. For the above reasons, it is necessary to design a temperature-sensitive color-changing fabric with high color change uniformity and capable of quickly changing its surface color. Summary of the Utility Model

[0005] To achieve the above purpose, the technical solution of the present utility model is as follows:

[0024] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the following further describes the embodiments of the present disclosure in a clearer and more detailed manner with reference to the accompanying drawings of the present embodiment. Note: The described embodiments are part of the embodiments of the present disclosure, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.
[0025] As shown in the attached Figure 1 to the attached Figure 3 As shown, the temperature-sensitive color-changing fabric provided by the embodiment of the present utility model is used for the uniform color change of the fabric and can quickly perform color change processing on the externally applied heat source; the temperature-sensitive color-changing fabric includes a fabric main body 1, and the fabric main body 1 includes interlaced textile warp threads 11, textile weft threads 12 and temperature-sensitive threads 13. Among them, the temperature-sensitive threads 13 are arranged on the same side as the textile warp threads 11 as the warp threads of the fabric, and the temperature-sensitive threads 13 are arranged on the same side as the textile weft threads 12 as the weft threads of the fabric. Then, heat-conducting wires 2 are interposed between adjacent warp threads and adjacent weft threads, and are applied to both the warp threads and weft threads of the fabric. Applying the textile technology of existing fabrics, the textile fabric will be processed by a textile machine. Through the interlacing of the three kinds of wires, namely the warp threads, the weft threads and the heat-conducting wires 2, the fabric can be woven; by using the heat-conducting wires 2, the uniform transfer of the heat source on the surface of the temperature-sensitive color-changing fabric can be realized, the heat transfer rate of the heat source can be increased, and the quick color change of the fabric is facilitated.
[0026] For better uniform color change of the temperature-sensitive color-changing fabric, as shown in Figure 2 As shown, the heat-conducting wires 2, the temperature-sensitive threads 13 and the warp threads and weft threads formed by the textile warp threads 11 and the textile weft threads can be woven into a plain weave structure by a textile machine. By applying the advantages of a plain weave fabric, such as many interlacing points, firm texture, scratch resistance, smooth surface, relatively light weight, good wear resistance and good air permeability, it is convenient for the heat source to quickly transfer heat to the surface of the fabric for color change use, and the use effect of the temperature-sensitive color-changing fabric is increased.
[0027] For better transferring body temperature to the temperature-sensitive color-changing fabric, as shown in Figure 3 As shown, the wires can be arranged in a double-strand manner to expand the contact area between the heat-conducting wires 2 and the heat source, increase the heat absorption rate of the temperature-sensitive color-changing fabric for heat, quickly transfer the heat to the temperature-sensitive threads 13, increase the color change uniformity of the fabric, and improve the temperature-sensitive color-changing effect of the fabric; and the uniform weaving of the heat-conducting wires 2 with the warp threads and weft threads is increased.
[0028] For better heat transfer and to ensure the elastic use of the heat-conducting wires 2 on the fabric, as shown in Figure 4As shown, the heat-conducting wire 2 can use a heat-conducting wire 21 and a textile thread 22. The two wires are twisted into a single wire body through a double-helix structure, which facilitates the textile production of subsequent textile machines; it increases the elasticity of the heat-conducting wire 2, realizes the integrity of the application and weaving of the heat-conducting wire 21 on the fabric, and improves the comfort and softness of the fabric surface.
[0029] Among them, it is worth noting that the heat-conducting wire 21 can use an aluminum-copper alloy material. The application of copper-aluminum alloy is simpler than other cast aluminum alloys, which is convenient for production and manufacturing. It has high thermal conductivity while having anti-corrosion function, is light and has high tensile strength, which is beneficial to the application on the temperature-sensitive color-changing fabric, facilitates the transfer of heat sources on the fabric, and improves the color-changing uniformity of the temperature-sensitive color-changing fabric.
[0030] To better facilitate the uniformity of color change on the temperature-sensitive color-changing fabric, as Figure 1 shown, a wear-resistant protective layer 3 can be set on the outside of the fabric body 1, which increases the wear resistance of the fabric, improves the wear of the fabric body 1, facilitates the transmission of heat source heat, and conducts color-changing applications; it extends the service life of the temperature-sensitive color-changing fabric, conducts protective treatment on the surface of the fabric, and increases the practicality of the temperature-sensitive color-changing fabric.
[0031] Among them, as Figure 5 shown, the wear-resistant protective layer 3 can include a PU coating 31 set on one side of the fabric body 1 and a PA coating 32 set on one side of the PU coating 31. The PU coating 31 is applied for its advantages of being soft, elastic, having good strength, thin layer, moisture permeability and air permeability; the PA coating 32 has good fastness to sunlight and climate, is not easy to turn yellow, has good transparency and compatibility, is beneficial to the production of colored coating products, has good washability, strong adhesion and low cost. The superposition setting of the two coatings inside and outside facilitates the combined use of the two coatings, increases the wear resistance and washability of the temperature-sensitive color-changing fabric, and is beneficial to the application of the temperature-sensitive color-changing fabric in the clothing field.
[0032] Of course, the above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches are also regarded as the protection scope of the present invention.
