Technical Field
[0001] The present application relates to the technical field of heat-generating clothing, and in particular to a heat-generating fabric and a method for making the same. Background Art
[0002] Keeping warm is one of the most important functions of clothing. In order to enhance the ability of traditional clothing to keep warm, the prior art has the following methods, such as putting a heating element similar to a hand warmer into clothing, or using a carbon fiber membrane or other heating element to fit the inside of clothing to achieve heating. However, it is difficult to flexibly produce according to actual patterns during the production process. Some methods use multiple coupled fiber strands for weaving, such as the document disclosed in application number "CN201980045402.4". Although it provides a production method different from traditional heating fabrics, the production process is complicated and has high requirements for the production process. Summary of the invention
[0003] The purpose of this application is to provide a heat-generating fabric and a method for manufacturing the same, so as to solve at least one of the above-mentioned technical problems.

[0006] Wherein, the heating element is suitable for generating heat after being powered on;
[0007] In the above implementation process, this solution cleverly uses the screen printing process to form the heating element. The screen printing process forms a conductive path while forming the heating element. When the heating element is connected to an external power supply, it can convert electrical energy into thermal energy to achieve heating of the fabric. The screen printing process is combined with fabric production. Screen printing itself can flexibly and quickly generate various patterns according to different needs. At the same time, there is no need to use a complicated weaving process to promote the formation of the heating element. It is only necessary to form a conductive heating element through screen printing, which is simpler to produce.
[0008] Preferably, the substrate layer is provided with two layers, and the heating element is provided between the two substrate layers;

[0016] In the above implementation process, multiple heating elements are independently controlled by the switch control unit, and multiple heating elements can realize heating in different areas respectively, so that users can make flexible adjustments according to actual needs. For example, if higher warmth retention performance is needed, multiple heating elements are turned on at the same time, otherwise, a small number of heating elements are turned on or all are turned off; in some usage scenarios, local heating can also be achieved by controlling some heating elements to turn on, which is convenient and flexible to use while also saving energy.
[0017] Preferably, the fabric layer is made of one or more materials selected from the group consisting of cotton, linen, silk, wool and chemical fiber.

[0047] Example
[0048] Keeping warm is one of the most important functions of clothing. In order to enhance the ability of traditional clothing to keep warm, the prior art has the following methods, such as putting a heating element similar to a hot pack into clothing, or using a carbon fiber membrane or other heating membrane to fit the clothing to achieve heating. It is difficult to flexibly produce according to the actual pattern during the production process; some methods use multiple coupled fiber strands for weaving, such as the document disclosed in the application number "CN201980045402.4", which provides a production method different from traditional heating fabrics, but the production process is complicated and has high requirements for the production process; in order to solve the above technical problems, this embodiment provides the following counting method:
[0049] For details, see Figure 1-4, this embodiment provides a heat-generating fabric, comprising a fabric layer 11 and at least one substrate layer 21; the substrate layer 21 is disposed on the fabric layer 11;
[0050] Specifically, a heating element 22 is provided on the substrate layer 21, and the heating element 22 is formed on the substrate layer 21 by a screen printing process, and the heating element 22 establishes a conductive path and forms at least one electrical contact for an external power source;
[0051] Wherein, the heating element 22 is adapted to generate heat after being powered on;
[0052] In the above scheme, the present scheme cleverly utilizes the screen printing process to form the heating element 22. The screen printing process forms a conductive path while forming the heating element 22. When the heating element 22 is connected to an external power supply, the electrical energy can be converted into thermal energy to achieve heating. The screen printing process is combined with fabric production. Screen printing itself can flexibly and quickly generate various patterns according to different needs. At the same time, there is no need to adopt a complicated weaving process to promote the formation of the heating element 22. It is only necessary to form a conductive heating element through screen printing, which is simpler to produce.
[0053] It is understandable that the heating element 22 is connected to the external power supply through its electrical contacts; in some embodiments, the connection between the electrical contacts and the power supply can be achieved by connecting wires; further, the connection guide can be embedded in the fabric layer 11 by sewing to achieve concealment, and of course it is understandable that the wires can also be directly led out.
[0054] It should be noted that the screen printing process is a well-known technology for those skilled in the art. It can be achieved by printing specific patterns made of specific materials on a certain substrate. For example, in the present embodiment, a heating element 22 is printed. The heating element 22 can be a heating electrode or other element that can generate heat by conducting electricity. In this regard, the present embodiment does not further elaborate on the specific method steps and principles of how the screen printing process forms the heating element 22.
[0055] For details, see Figure 2 In some embodiments, the substrate layer 21 has two layers, and the heating element 22 is disposed between the two substrate layers 21;
[0056] In the above solution, the heating element 22 is disposed between the two substrate layers 21 to fully protect the heating element 22 , effectively extending the service life of the heating element 22 while also protecting the user during use.
[0057] For details, see Figure 1 In some embodiments, the fabric layer 11 is provided with a layer; that is, in practical applications, the base material layer 21 may be provided close to the human body, or the fabric layer 11 may be provided close to the human body;
[0058] Furthermore, an attachment mechanism is provided on a side of the fabric layer 11 away from the substrate layer 21 and / or on the outermost side opposite to the fabric layer 11;
[0059] In the above scheme, the practicality of the heatable fabric provided in the present application can be further improved by setting up an attachment mechanism, that is, the heatable fabric can be connected to the object to be heated through the attachment mechanism, such as quickly attaching the heatable fabric to clothing through the attachment mechanism, and in some applications it can also be attached to a seat cushion, etc.
[0060] Further, the attachment mechanism includes, but is not limited to, connecting lines, zippers, buttons, Velcro, straps or tape;
[0061] Taking Velcro as an example, in some implementations, a male sticker may be provided on a seat cushion, and a corresponding female sticker may be provided on the heatable fabric, so as to achieve a quick connection between the heatable fabric and the seat cushion; of course, the above is only one example, and this embodiment does not limit this.
[0062] Specifically, in some embodiments, when only one fabric layer 11 is provided, the attachment mechanism may be provided on the base material layer 21 opposite to the fabric layer 11; of course, it is understandable that the attachment mechanism may still be provided on one side of the fabric layer 11, and it may also be provided only on a partial area of the fabric layer 11.
[0063] Specifically, the substrate layer 21 is made of one or more materials selected from polytetrafluoroethylene, polyphenylene sulfide, polyester and polyimide;
[0064] In the above scheme, this scheme selects the above material as the substrate layer 21, and utilizes its high temperature resistance and insulation characteristics to fully ensure that the heating element 22 can achieve stable heating. At the same time, the above material also has flexibility, so it can be more adapted to the characteristics of the fabric and ensure the softness of the fabric.
[0065] In other embodiments, the substrate layer 21 may be made of one or more materials selected from the group consisting of cotton, wool, silk, linen, and chemical fiber fabrics. It is understandable that in some embodiments, the substrate layer 21 may not be provided. For example, when the fabric layer 11 itself already has sufficient protective density to achieve a function similar to that of the substrate layer 21, the substrate layer 21 may be omitted and the heating element 22 may be directly printed on the fabric layer 11.
[0066] Specifically, the fabric layer 11 is made of one or more materials selected from the group consisting of cotton, linen, silk, wool, and chemical fiber.
[0067] Further, the thickness of the substrate layer 21 is 0.03-0.05 mm;
[0068] It has been found through experiments that the substrate layer 21 with this thickness can fully guarantee its insulation protection performance while ensuring lightness and thinness.
[0069] For details, see Figure 3 , further comprising a switch control unit 31 electrically connected to the heating element 22, the switch control unit 31 being used to control the opening or closing of the heating circuit of the heating element 22;
[0070] In the above solution, further providing a switch control unit 31 can achieve more flexible control over the heating element 22, thereby improving the user's convenience and experience.
[0071] Furthermore, a plurality of heating elements 22 are provided and are respectively distributed in different areas of the fabric layer 11 , and the plurality of heating elements 22 are independently controlled by the switch control unit 31 ;
[0072] In the above scheme, multiple heating elements 22 are independently controlled by the switch control unit 31, and the multiple heating elements 22 can respectively realize heating in different areas, so that users can flexibly adjust according to actual needs. For example, if higher warmth retention performance is required, multiple heating elements 22 are turned on at the same time, otherwise, a small number of heating elements 22 are turned on or all are turned off; in some usage scenarios, local heating can also be achieved by controlling some of the heating elements 22 to be turned on, which is convenient and flexible to use while also saving electricity.
[0073] It should be noted that the principle of the switch control unit 31 realizing the opening or closing of the heating circuit of the heating element 22, or independently controlling the opening or closing of multiple heating circuits of the heating elements 22, is a relatively mature technology in the prior art, so this solution will not be further elaborated on this.
[0074] Furthermore, the switch control unit 31 may adopt FPC to meet the flexibility requirements of the scarf; of course, adopting FPC is only one of the preferred methods, and it may also adopt a hard circuit board, which is not limited in this embodiment.
[0075] Furthermore, in some other embodiments, a signal control module is also included, which includes but is not limited to a Bluetooth module, a wifi module, etc.; wherein the signal control module is electrically connected or signal-connected to the switch control unit 31; that is, the user can flexibly control the switch control unit 31 through a remote control or a mobile phone or other device.
[0076] Specifically, a first pattern is formed on the fabric layer 11, and a second pattern is formed on the heating element 22, and the first pattern is the same as the second pattern;
[0077] In other embodiments, the second pattern pattern has the same hollowed-out portion as the first pattern pattern so that the second pattern pattern complements the first pattern pattern;
[0078] In the above scheme, when a pattern is formed on the fabric layer 11 by knitting or other means, since the heating element 22 in this scheme can be formed by a printing process, a corresponding pattern can be generated in conjunction with the pattern on the fabric layer 11. This can provide a new production idea for the production of fabrics with decorative patterns, which is both interesting and practical.
[0079] Specifically, in some implementations, the heatable fabric provided in this embodiment may further include a power source body 23; that is, the fabric has a certain energy storage capacity;
[0080] Furthermore, the power source body 23 may be a flexible sheet-shaped lithium battery; the use of a flexible sheet-shaped lithium battery can better fit the soft characteristics of the fabric, avoiding the fabric surface appearing too abrupt or affecting the flexibility of the fabric after the battery is installed.
[0081] Specifically, this embodiment also provides a method for making a heat-generating fabric, which includes the following steps:
[0082] S1, printing the printing ink in a designated pattern on the substrate layer 21 by screen printing process;
[0083] S2, allowing the printing ink forming a designated pattern to solidify on the substrate layer 21 to form the heating element 22;
[0084] S3, fixing the base material layer 21 and the fabric layer 11, wherein the fixing method includes sewing or heat pressing.
[0085] Further, in step S2, the curing method step of the printing ink includes exposing to radiation or applying electrical energy or adding chemical reagents;
[0086] The methods of exposure to radiation include but are not limited to ultraviolet rays, light pulses, lasers, plasma, microwaves, etc.
[0087] Specifically, the printing ink includes a solvent in which nano-metal or nano-metal oxide particles are dispersed; or a solvent in which carbon nanotubes are dispersed;
[0088] Furthermore, in some embodiments, the solvent in which nano-metal or nano-metal oxide particles are dispersed may be aqueous silver ink in which nano-silver particles are dispersed, or aqueous nano-gold ink, aqueous nano-copper ink, etc.
[0089] Specifically, in step S3, the fixing method of the substrate layer 21 and the fabric layer 11 includes sewing or hot pressing;
[0090] In one embodiment, the base material layer 21 and the fabric layer 11 are connected by sewing; further, in some application scenarios, the sewing thread used to fix the base material layer 21 and the fabric layer 11 can be a conductive wire (which may be coated with an insulating material), which is inserted into the electrical contact of the heating element 22 and then led out; subsequently, the wire is connected to a power source to achieve energy supply.
[0091] In another embodiment, the base material layer 21 and the fabric layer 11 are connected by heat pressing. In some application modes, a hot pressing adhesive with adhesive properties may be further provided between the base material layer 21 and the fabric layer 11. During subsequent heat pressing, the hot pressing adhesive with adhesive properties melts and adheres the fabric layer 11 and the base material layer 21 together to achieve connection between the two.
[0092] In some embodiments, when the substrate layer 21 is not provided, the heating element 22 may be directly printed on the fabric layer 11 in step S1.
[0093] It should be noted that the printing process includes thermal transfer, thermal sublimation, screen printing, digital printing, four-color printing, etc., and this solution selects the screen printing process and combines it with fabric production, and further combines it with heat-generating fabrics, making full use of the characteristics of screen printing and fabric fabrics. While retaining the softness of the fabric, it also achieves the effect of flexibly setting the pattern of the heating element 22 according to different pattern requirements, providing a new production idea for the production of heat-generating fabrics.
[0094] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.
[0095] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application are within the scope of the technical solution of the present application.
