[0032] The embodiments of the present disclosure provide a smart textile that can display different colors according to the temperature of the smart textile under any lighting conditions, thereby more intuitively indicating the current temperature of the textile, and more clearly reminding the user of the current temperature of the textile, avoiding safety issues caused by overheating of the textile, thereby improving the safety of the textile.

[0033] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0034] FIG1 is a schematic diagram of a smart textile according to an exemplary embodiment of the present disclosure.

[0035] 1 , an embodiment of the present disclosure provides a smart textile 100 , which may include a first conductive yarn 101 woven along a weft direction, a thermochromic yarn 102 woven along a weft direction, and a polymer optical fiber (POFs) 103 woven along a weft direction.

[0036] The first conductive yarn 101 can be a silver-plated conductive yarn or a conductive yarn made of other materials; electrodes extending along the warp direction are embroidered on both ends of the first conductive yarn 101, that is, a first electrode 1061 is embroidered on one end of the first conductive yarn 101, and a second electrode 1062 is embroidered on the other end of the first conductive yarn 101. The first electrode 1061 and the second electrode 1062 can serve as the positive electrode and the negative electrode, respectively; the first conductive yarn 101 generates heat when the electrodes are energized, causing the temperature of the smart textile 100 to change.

[0037] Thermochromic yarn 102 is a yarn that can change color according to temperature changes. It can be obtained by adding thermochromic substances or other color-changing materials to the yarn. The thermochromic material 102 can indicate changes in the heating temperature of the textile. Under normal circumstances, the thermochromic yarn 102 changes color obviously in a light environment and does not change obviously in a dark environment. Therefore, when the light intensity on the surface of the smart textile 100 is greater than a preset value, the thermochromic yarn 102 can be used to present different colors according to changes in the temperature of the smart textile 100.

[0038] In some embodiments, when the first conductive yarn 101 generates heat, the temperature of the smart textile 100 increases. When the temperature of the smart textile 100 reaches a preset temperature, the color of the thermochromic yarn 102 begins to change, indicating that the smart textile 100 is being heated. Both the preset temperature and the color of the thermochromic yarn can be set as needed. For example, when the smart textile 100 is below 30°C, the thermochromic yarn 102 is purple. When the smart textile 100 is heated above approximately 30°C, the thermochromic yarn 102 gradually changes from purple to pink, indicating that the fabric is being heated.

[0039] The two ends of the polymer optical fiber 103 are respectively collected into bundles 104 and connected to the light source device 1051 and the light source device 1052, where the light source device can be, for example, an LED (Light-Emitting Diode) light source or other light sources; the color of the light emitted by the light source device can be determined according to the current temperature of the smart textile. For example, a temperature and color mapping table can be set, and the color of the light can be determined according to the temperature of the textile through programming; the polymer optical fiber can present the color of the light emitted by the light source device, that is, the color of the light emitted by the light source device is the same as the color presented by the polymer optical fiber, and the color presented by the polymer optical fiber changes with the change of the color of the light emitted by the light source device, so as to intuitively display the current temperature of the smart textile.

[0040] For example, the edges of the polymer optical fibers can be bundled together, and visible light of a target color emitted by a light source device can be transmitted along the axial direction of the polymer optical fiber. The visible light of the target color within the polymer optical fiber is refracted radially out of the polymer optical fiber, causing the textile to exhibit the target color. The light source device can be turned on and off by a control device, and the color of the visible light emitted by the light source device can also be controlled by the control device.

[0041] In the embodiment of the present disclosure, the light source device can be always in the on state, that is, the polymer optical fiber 103 can be always in the luminous state; the light source device can also be in the on state when the light intensity on the surface of the smart textile 100 is less than or equal to a preset value, that is, the polymer optical fiber 103 can be in the luminous state when the light intensity on the surface of the smart textile 100 is less than or equal to a preset value; since the thermochromic yarn 102 changes color obviously in a light environment, and the polymer optical fiber 103 glows more obviously in a dark environment, the smart textile provided by the embodiment of the present disclosure can display color according to the temperature of the smart textile in both light and dark environments, that is, the visualization effect can adapt to any lighting conditions to intuitively indicate the current temperature of the smart textile.

[0042] The smart textile provided by the embodiment of the present disclosure has a first conductive yarn whose electrode generates heat when energized, causing the temperature of the textile to change; the thermochromic yarn can present different colors according to the change in the temperature of the textile when the light intensity is greater than a preset value, and the polymer optical fiber can more obviously present different colors of light according to the temperature of the textile when the light intensity is less than a preset value; the smart textile can generate heat, and the entire textile can display different colors according to the temperature of the smart textile under any lighting conditions, thereby more intuitively indicating the current temperature of the textile, so as to more clearly remind the user of the current temperature of the textile, avoid safety problems caused by overheating of the textile, and thus improve the safety of the textile.

[0043] In the embodiment of the present disclosure, POF yarn with a diameter of 0.25 mm, 150D / 2 thermochromic yarn and 3 strands of 40D silver-plated heating yarn can be used for weaving, and yarns of other thicknesses can also be used, which is not limited in the present disclosure.

[0044] In some embodiments, the smart textile 100 further includes insulating yarns woven along the warp direction, which can be made of any non-conductive material, such as polyester fiber; the first conductive yarns, thermochromic yarns, and polymer optical fibers woven along the weft direction are all interwoven with the insulating yarns woven along the warp direction to form the smart textile 100.

[0045] In some embodiments, after the weaving process, conductive yarns can be embroidered on the smart textile along the warp direction as the above-mentioned electrodes; that is, the above-mentioned electrodes can be conductive yarns embroidered on both ends of the smart textile along the warp direction. To distinguish them from the first conductive yarns woven along the weft direction, the conductive yarns serving as electrodes can be called second conductive yarns, wherein the first conductive yarn and the second conductive yarn can both be silver-plated conductive yarns.

[0046] Specifically, the second conductive yarn is embroidered as a pair of electrodes on the smart textile along the warp direction to form a fabric with a larger fabric density. This can avoid the stretching of the electrode area during the embroidery process due to the low fabric density (for example, 60 stitches per inch). For example, the fabric density can be 120 stitches per inch, and the resulting fabric has a relatively stable structure.

[0047] In the disclosed embodiment, conductive yarns are embroidered on the textile along the warp direction through an embroidery process, which replaces the process of manufacturing a pair of electrodes, can save electrode manufacturing time, and improve the manufacturing efficiency of the textile; at the same time, the direction of the embroidery needle is consistent with the warp direction, which can ensure close contact between the interweaving point and the conductive weft yarn (that is, the conductive yarn extending along the weft direction), thereby improving the heating efficiency of the textile.

[0048] In some embodiments, the smart textile may be a double-sided textile, the front side of which includes the first conductive yarn and the thermochromic yarn woven in the weft direction, and the back side of which includes the first conductive yarn and the polymer optical fiber woven in the weft direction.

[0049] The smart textile provided by the disclosed embodiments is a double-sided structure. Compared to single-sided structures, this allows for more yarns to be woven into the fabric at the same fabric size. The increased number of silver-coated conductive yarns, thermochromic yarns, and polymer optical fibers not only improves the energy efficiency of heating but also visually changes the color of the thermochromic yarns and polymer optical fibers. Furthermore, with conductive yarns and thermochromic yarns on the front and conductive yarns and polymer optical fibers on the back, a better balance between heating and color indication can be achieved.

[0050] FIG2 is a schematic diagram of a weaving structure and yarn insertion sequence of a smart textile in an exemplary embodiment of the present disclosure.

[0051] Referring to Figure 2, the left side shows the weaving patterns of the front (Face) and back (Back) of a double-sided textile, the middle side shows the weaving pattern fed into a weaving machine, and the right side shows the yarn insertion sequence of the first conductive yarn, thermochromic yarn, and polymer optical fiber in the double-sided textile. The numbers on the lower right side represent the yarn insertion sequence on the loom.

[0052] The smart textile in the embodiment of the present disclosure can adopt a double-layer fabric structure and be woven simultaneously; the textile can adopt the diamond pattern shown in Figure 2, providing a long float structure for inserting polymer optical fibers; the polymer optical fibers are woven on the back of the textile, so that the back of the textile has a satisfactory lighting effect; and most of the thermochromic yarns and silver-plated conductive heating yarns are displayed on the front of the fabric. The thermochromic yarn can be inserted three times in a row, which can increase the coverage of the thermochromic yarn on the fabric and improve the color-changing effect of the fabric when heated.

[0053] FIG3 is a schematic diagram showing the connection between the smart textile and a control device and other devices in an exemplary embodiment of the present disclosure.

[0054] 3 , the first electrode 1061 and the second electrode 1062 of the smart textile 100 may be connected to the anode and cathode of a power supply device 201 , respectively. The power supply device 201 is configured to supply power to the first electrode 1061 and the second electrode 1062 . The power supply device 201 may, for example, use a 12V power supply. The power supply device 201 may be connected to a motor driver 202 to receive signals sent by the motor driver 202 .

[0055] In the embodiment of the present disclosure, after the power supply device 201 supplies power to the first electrode 1061 and the second electrode 1062 , the first conductive yarn 101 is heated, and the temperature of the smart textile 100 gradually increases.

[0056] The smart textile 100 in the embodiment of the present disclosure may further include a temperature sensor 107, which may be embedded in the smart textile 100 and used to collect the current temperature of the smart textile 100 in real time; the temperature sensor 107 may be communicatively connected to the control device 203, and the temperature sensor 107 transmits the collected current temperature of the smart textile 100 to the control device 203. The control device 203 may control the color of the light emitted by the light source device according to the current temperature of the smart textile 100.

[0057] In some embodiments, the control device 203 can control the light source device to emit light of different colors when the current temperature is in different temperature ranges; for example, when the temperature is lower than 30°C, the light source device emits blue light, so that the polymer optical fiber appears blue; when the temperature is between 30 and 36°C, the light source device emits yellow light, so that the polymer optical fiber appears yellow; when the temperature is higher than 36°C, the light source device emits red light, so that the polymer optical fiber appears red.

[0058] Specifically, the control device 203 may include a light source device controller 2031, a microcontroller 2032 and a computer 2033, wherein the light source device controller 2031 can receive the current temperature of the smart textile collected by the temperature sensor 107, and control the light source device 1051 and the light source device 1052 to emit light of different colors according to the current temperature. The light source device controller 2031 can be an LED controller, and the power supply of the light source device controller 2031 can be provided by the power bank 204; the microcontroller 2032 can use an ESP32 microcontroller, and the microcontroller 2032 can be connected to the light source device controller 2031, the motor driver 202 and the computer 2033 respectively. The computer 2033 can be, for example, a PC (Personal Computer) for processing data sent by the microcontroller 2032.

[0059] In the embodiment of the present disclosure, the control device 203 can be connected to the humidity sensor 206 and the air flow rate sensor 207 , and the control device 203 is used to receive the ambient humidity measured by the humidity sensor 206 and the ambient air flow rate measured by the air flow rate sensor 207 .

[0060] In some embodiments, the control device 203 can predict the target comfort temperature based on the ambient humidity and the ambient air flow rate, or the control device 203 can predict the target comfort temperature of the target object based on the basic information of the target object, the ambient humidity and the ambient air flow rate, wherein the basic information of the target object is obtained by the control device 203, and the target object is a user using the smart textile, and the basic information of the target object may include the user's gender and age.

[0061] In the disclosed embodiment, the user's target comfort temperature can be predicted, and the temperature of the textile can be adjusted according to the predicted target comfort temperature, that is, the temperature can be adjusted according to the user's preference, thereby improving the user's comfort.

[0062] Specifically, the microcontroller 2032 is connected to the temperature sensor 205 for measuring the ambient temperature, the humidity sensor 206 for measuring the ambient relative humidity, and the air flow rate sensor 207 for measuring the ambient air flow rate. The microcontroller 2032 receives the ambient temperature measured by the temperature sensor 205, the ambient relative humidity measured by the humidity sensor 206, and the ambient air flow rate measured by the air flow rate sensor 207, and sends the ambient temperature, ambient relative humidity, and ambient air flow rate to the computer 2033. The computer 2033 can display the ambient temperature on the screen for the user to view in real time. The computer 2033 can predict the target comfort temperature based on the ambient humidity and ambient air flow rate, or predict the target comfort temperature of the target object based on the basic information of the target object, the ambient humidity, and the ambient air flow rate, and send the target comfort temperature to the microcontroller 2032. The target comfort temperature refers to the temperature that makes the target object feel most comfortable under the conditions of specific ambient humidity and specific air flow rate. The target object is a user using the smart textile. The temperature that the target object feels most comfortable can be called the user's optimal preferred temperature. For example, PMV (Predicted Mean Average) can be used. The thermal comfort evaluation index PMV (Predicted Mean Perceived Temperature) determines the user's optimal preferred temperature, and the PMV value of 0 is taken as the optimal comfort point, and the temperature point corresponding to the optimal comfort point is taken as the user's optimal preferred temperature.

[0063] Specifically, the computer 2033 can obtain the user's basic information (age and gender), and input the user's basic information, ambient humidity (%RH) and air flow rate (m / s) into an artificial neural network model (ANN) to obtain the target comfort temperature (°C) of the target object.

[0064] FIG4 is a schematic diagram showing the structure of an artificial neural network model according to an example.

[0065] Referring to Figure 4, the artificial neural network model may include an input layer, a hidden layer 1, a hidden layer 2, and an output layer, wherein the input layer is used to input the user's age, gender, relative humidity of the environment, and air flow rate, the number of neurons in the hidden layer 1 may be 145, the number of neurons in the hidden layer 2 may be 4, and the output layer is used to output the predicted target comfort temperature.

[0066] In the embodiment of the present disclosure, during the training process of the artificial neural network model, training data can be obtained from the ASHRAE Global Thermal Comfort Database, which includes a thermal comfort dataset, which includes comfort levels corresponding to different ages, different genders, different temperatures, different humidity, and different air flow rates; calculations are performed using the machine learning tool Scikit-Learn in Python; a Sigmoid activation function and a mean square error (MSE) can be used as a loss function.

[0067] In an embodiment of the present disclosure, the training process of the artificial neural network model may include: obtaining multiple sets of training data, each set of training data including user age, user gender, humidity, air flow rate and target temperature, wherein the target temperature refers to the temperature that maximizes comfort when the user age, user gender, humidity and air flow rate are determined; using the target temperature in each set of training data as a training label, inputting the user age, user gender, humidity and air flow rate in each set of training data into the artificial neural network model to be trained, obtaining a predicted comfort temperature, adjusting the model parameters of the artificial neural network model according to the difference between the target temperature and the predicted comfort temperature, so that the difference between the predicted comfort temperature obtained by the artificial neural network model and the target temperature meets the preset conditions, and completing the training of the artificial neural network model.

[0068] In some embodiments, after the control device predicts and obtains the target comfort temperature, the power supplied by the power supply device may be adjusted according to the target comfort temperature and the current temperature of the smart textile, thereby adjusting the temperature of the smart textile.

[0069] 3 , when the current temperature of the smart textile 100 is lower than the target comfort temperature, the control device 203 is configured to increase the power supplied by the power supply device 201, thereby increasing the heat generated by the first conductive yarn 101 and thereby raising the current temperature of the smart textile 100. When the current temperature of the smart textile 100 is higher than the target comfort temperature, the control device 203 is configured to decrease the power supplied by the power supply device 201, thereby reducing the heat generated by the first conductive yarn 101 and thereby lowering the current temperature of the smart textile 100.

[0070] Specifically, the computer 2033 can compare the current temperature of the smart textile 100 collected by the temperature sensor 107 with the target comfort temperature predicted by the computer 2033. When the current temperature of the smart textile 100 is lower than the target comfort temperature, the computer 2033 sends a control signal to the microcontroller 203, and the microcontroller 203 increases the power supplied by the power supply device 201 to the smart textile through the motor driver 202, so that the heat generated by the first conductive yarn 101 in the smart textile 100 is increased, thereby increasing the temperature of the smart textile 100. When the current temperature of the smart textile 100 is higher than the target comfort temperature, the computer 2033 sends a control signal to the microcontroller 203, and the microcontroller 203 decreases the power supplied by the power supply device 201 to the smart textile through the motor driver 202, so that the heat generated by the first conductive yarn 101 in the smart textile 100 is reduced, thereby lowering the temperature of the smart textile 100.

[0071] The smart textile provided by the embodiments of the present disclosure can adjust the temperature of the textile according to the current temperature of the textile and the predicted target comfort temperature, without the need for manual temperature adjustment, thereby improving the convenience of use; at the same time, automatic temperature adjustment can keep the textile within a certain temperature range, which helps to extend the service life of the textile; when the current temperature of the textile is greater than the predicted target comfort temperature, the control device reduces the power supply of the power supply device, thereby reducing the heat generated by the conductive yarn, thereby lowering the temperature of the textile, avoiding safety problems caused by excessive temperature, and improving the reliability of the textile; at the same time, it can avoid the waste of resources caused by excessive temperature and save energy.

[0072] FIG5 is a diagram illustrating the relationship among ambient relative humidity, air flow rate, predicted temperature, and actual temperature of a textile according to an example.

[0073] In the disclosed embodiment, using the artificial neural network model input of a user's age of 20 and gender of female as an example, as shown in Figure 5, the relative humidity remained essentially constant during the test, while the predicted temperature (°C) increased moderately with increasing air velocity (m / s). From 0 to 14 seconds, the curves of the predicted temperature (°C) and the actual temperature (°C) exhibited different patterns; from 14 to 37 seconds, the fluctuations of the air velocity (m / s), predicted temperature (°C), and actual temperature (°C) curves were roughly the same. This indicates that the prediction model has a high correlation with the actual fabric temperature after 14 seconds, indicating that the artificial intelligence system reaches stability within 14 seconds of powering on.

[0074] FIG6 is a schematic diagram showing a smart textile in a light environment and a dark environment according to an example.

[0075] Referring to Figure 6, the silver-plated conductive yarn in the textile is being heated. In a light environment, the thermochromic yarn on the front of the textile will change color according to the heating temperature of the textile. At the same time, there may be a small amount of thermochromic yarn on the back of the textile, which will also change color according to the heating temperature of the textile. The POF on the back of the textile presents the color of the light emitted by the LED. The color of the light emitted by the LED is determined according to the heating temperature of the textile. Since it is a light environment, the light presented by the POF is not obvious. In a dark environment, the POF on the back of the textile presents the color of the light emitted by the LED. At this time, the light presented by the POF is obvious. Therefore, the smart textile provided by the embodiment of the present disclosure can display color according to the temperature of the smart textile in both light and dark environments, that is, the visualization effect can adapt to any lighting conditions to intuitively indicate the temperature of the smart textile.

[0076] The smart textiles provided by the embodiments of the present disclosure can be applied to multiple fields, such as clothing, heating, automobiles, medical equipment, aerospace, etc.; in the clothing field, smart textiles can be used as clothing to provide personalized and comfortable heating for individuals in cold weather conditions, which is especially useful for outdoor workers, athletes and people who need to keep warm; in the heating field, smart textiles can be integrated into home and building heating systems, which can reduce energy consumption and costs while providing greater comfort for occupants; in the medical equipment field, smart textiles can be used in medical devices such as heating pads, blankets and clothes to provide personalized and comfortable heating for patients with medical conditions that require warmth; in the aerospace field, smart textiles can be used in aerospace applications such as space suits and spacecraft insulation to provide personalized and efficient heating for astronauts.
