It can also integrate sensors and other devices to monitor human health data. It can also be used to make hot compress therapy products, such as hot compress pads, waist supports, knee supports, etc., to relieve muscle pain and promote blood circulation. It can also be applied to medical heat preservation equipment, such as infant incubators, etc.

[0004] The existing carbon nanotube electric heating textile cloth has a complex heating structure, making it difficult to use in the later stage and prone to failure. Therefore, a carbon nanotube electric heating textile cloth is proposed to solve the above problems. SUMMARY

[0008] The carbon nanotube electric heating textile cloth of the utility model is set between the copper film and the cloth, coated with conductive silver paste to increase the conductive contact and reduce the contact resistance, then dried at high temperature to solidify the conductive silver paste, the cloth is tightly combined with the copper film through the conductive silver paste to form an electrode, and the wire is pressure-welded to the power source using the fixing nail; when a corresponding voltage direct current is input, a current path is formed, electric energy is converted into heat energy, the cloth realizes the heating function, and the structure is simple and convenient to use in the later stage.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] like Figure 1 As shown, a carbon nanotube electrothermal textile fabric includes a carbon nanotube fabric 1, a conductive copper film 2, and a conductive silver paste 3. The carbon nanotube fabric 1 is connected to the conductive copper film 2, and the carbon nanotube fabric 1 is connected to the conductive copper film 2 through the conductive silver paste 3. It also includes two fixing nails 4, two wires 5, and a power source 6. Each end of the conductive copper film 2 has a through hole 7, and each of the two through holes 7 is connected to a fixing nail 4. Each of the two fixing nails 4 is connected to a wire 5, and the two wires 5 are connected to the power source 6.

[0014] Specifically, carbon nanotube fabric 1 contains carbon nanotube slurry. The carbon nanotube slurry is mainly a separation liquid containing carbon nanotubes and is an aqueous material. The fabric is immersed in the carbon nanotube slurry to fully combine the carbon nanotube molecules with the fiber structure. Then, the excess slurry is squeezed out to control the carbon nanotube composite concentration on the fabric. After the separation liquid in the fabric has completely evaporated, the remaining carbon nanotubes are tightly combined with the fabric fibers to form a carbon nanotube-fiber composite fabric.

[0015] Specifically, since the entire fabric needs to be heated evenly, electrodes need to be made to optimize the current distribution and achieve uniformity of the overall current density. Here, conductive copper film 2 and conductive silver paste 3 are used to make electrodes. At the same time, considering that the wire 5 is a rigid material and the fabric is a soft material, conductive copper film 2 is used for bonding to achieve a rigid-flexible connection. The front of the conductive copper film 2 is conductive copper and the back is conductive adhesive.

[0016] Specifically, since the copper film is a connecting intermediate material, the contact resistance between the copper film and the cloth is large, in order to reduce the contact resistance, the conductive silver paste 3 is used to connect the copper film and the cloth; the conductive silver paste 3 is in a liquid state when it is not solidified, and can be well attached and penetrated to the surface and inside of the cloth, and the two sides of the conductive silver paste are connected with the soft material (cloth) and the hard material (conductive copper film) respectively. Between the copper film and the cloth, the conductive silver paste is coated to increase the conductive contact and reduce the contact resistance, and then high-temperature drying is performed until the conductive silver paste is solidified, the cloth is tightly combined with the copper film through the conductive silver paste, and an electrode is formed.

[0017] Specifically, in order to connect the wire and the power supply, a hard connection mode is adopted, and a fixed nail is used to press the wire and the power supply; after the manufacturing is completed, a corresponding voltage direct current is input, a current path is formed, electric energy is converted into heat energy, and the cloth realizes the heating function.

[0018] The carbon nanotube electric heating textile cloth is set between the copper film and the cloth, the conductive silver paste is coated to increase the conductive contact and reduce the contact resistance, and then high-temperature drying is performed until the conductive silver paste is solidified, the cloth is tightly combined with the copper film through the conductive silver paste, an electrode is formed, the fixed nail is used to press the wire and the power supply, a corresponding voltage direct current is input, a current path is formed, electric energy is converted into heat energy, and the cloth realizes the heating function, and the structure is simple and convenient to use in the later period.
