[0031] The exemplary embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0032] Figure 1 is a schematic diagram of a smart textile in an exemplary embodiment of the present disclosure.

[0033] refer to Figure 1The embodiment of the present disclosure provides a smart textile 100, which may include a first conductive yarn 101 woven along the weft direction, a thermochromic yarn 102 woven along the weft direction, and a polymer optical fiber (Polymeric Optical Fibres, POFs) 103 woven along the weft direction.

[0034] 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 a positive electrode and a 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.

[0035] 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 into the yarn. Thermochromic material 102 can indicate changes in the heating temperature of the textile. Usually, the thermochromic yarn 102 changes color obviously in a light environment, but not 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.

[0036] In some embodiments, when the first conductive yarn 101 is heated, the temperature of the smart textile 100 increases; when the temperature of the smart textile 100 rises to a preset temperature, the color of the thermochromic yarn 102 begins to change to indicate that the smart textile 100 is being heated; wherein the preset temperature and the color of the thermochromic yarn can be set according to actual needs. For example, when the smart textile 100 is below 30°C, the thermochromic yarn 102 is purple; when the smart textile 100 is heated to above about 30°C, the thermochromic yarn 102 gradually changes from purple to pink to indicate that the fabric is being heated.

[0037] 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, wherein 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.

[0038] For example, the edges of the polymer optical fibers can be bundled together, the visible light of the target color emitted by the light source device can be transmitted along the axial direction of the polymer optical fiber, and the visible light of the target color in the polymer optical fiber is refracted from the radial direction of the polymer optical fiber, so that the textile presents the target color. The turning on and off of the light source device can be controlled by the control device, and the color of the visible light emitted by the light source device can also be controlled by the control device.

[0039] 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; because 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 a light environment and a dark environment, that is, the visualization effect can adapt to any lighting conditions to intuitively indicate the current temperature of the smart textile.

[0040] In the smart textile provided by the embodiment of the present disclosure, the electrode of the first conductive yarn generates heat when power is supplied to the electrode, so that the temperature of the textile changes; the thermochromic yarn can present different colors according to the change of the temperature of the textile when the light intensity is greater than a preset value, and the polymer optical fiber can present light of different colors according to the temperature of the textile more obviously when the light intensity is less than a preset value; the smart textile can generate heat, and under any lighting conditions, the whole textile can display different colors according to the temperature of the smart textile, thereby indicating the current temperature of the textile more intuitively, so as to more obviously 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.

[0041] 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.

[0042] In some embodiments, the smart textile 100 also includes insulating yarns woven along the warp direction, and the insulating yarns can be made of any non-conductive material, for example, 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.

[0043] In some embodiments, after the weaving process, the conductive yarn can be embroidered on the smart textile along the warp direction as the above-mentioned electrode; that is, the above-mentioned electrode can be the conductive yarn embroidered on both ends of the smart textile along the warp direction. To distinguish it from the first conductive yarn woven along the weft direction, the conductive yarn serving as the electrode can be called the second conductive yarn, wherein the first conductive yarn and the second conductive yarn can both be silver-plated conductive yarns.

[0044] 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 lower 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.

[0045] In the disclosed embodiment, the conductive yarn is embroidered on the textile along the warp direction through an embroidery process, which replaces the process of manufacturing a pair of electrodes, can save the time of electrode manufacturing 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 the 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.

[0046] In some embodiments, the smart textile may be a double-sided textile, the front side of which includes a first conductive yarn and a thermochromic yarn woven in a weft direction, and the back side of which includes a first conductive yarn and a polymer optical fiber woven in a weft direction.

[0047] The smart textile provided by the embodiment of the present disclosure is a double-sided structure. Compared with a single-sided structure, the double-sided structure can allow more yarns to be woven into the fabric at the same fabric size. The increase in the number of silver-plated conductive yarns, thermochromic yarns and polymer optical fibers not only improves the energy efficiency of heating, but also makes the color changes of thermochromic yarns and polymer optical fibers have a visual effect; in addition, the front side is conductive yarn and thermochromic yarn, and the back side is conductive yarn and polymer optical fiber, which can achieve a better balance effect in terms of heating and color indication.

[0048] Figure 2 It is a schematic diagram of the weaving structure and yarn introduction sequence of the smart textile in an exemplary embodiment of the present disclosure.

[0049] refer to Figure 2 , the left side shows the weaving patterns of the front side (Face) and the back side (Back) of the double-sided textile, the middle shows the weaving pattern fed into the weaving machine, the right side shows the yarn insertion order of the first conductive yarn, thermochromic yarn and polymer optical fiber in the double-sided textile, and the numbers on the lower right side represent the yarn insertion order on the loom.

[0050] The smart textile in the embodiment of the present disclosure can adopt a double-layer fabric structure and be woven at the same time; the textile can adopt Figure 2 The diamond pattern shown gives a long float structure for the insertion of 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; while most of the thermochromic yarns and silver-coated 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 when the fabric is heated.

[0051] Figure 3 Schematic diagram of connecting a smart textile with a control device and other devices in an exemplary embodiment of the present disclosure.

[0052] refer to Figure 3 The first electrode 1061 and the second electrode 1062 of the smart textile 100 can be connected to the anode and the cathode of the power supply device 201 respectively. The power supply device 201 is used to supply power to the first electrode 1061 and the second electrode 1062. The power supply device 201 can use a 12V power supply, for example; the power supply device 201 can be connected to the motor driver 202 to receive the signal sent by the motor driver 202.

[0053] 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.

[0054] 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, and 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.

[0055] 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.

[0056] 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 may 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 may be an LED controller, and the power supply of the light source device controller 2031 may be provided by the power bank 204; the microcontroller 2032 may use an ESP32 microcontroller, and the microcontroller 2032 may be connected to the light source device controller 2031, the motor driver 202 and the computer 2033 respectively, and the computer 2033 may be, for example, a PC (Personal Computer) for processing data sent by the microcontroller 2032.

[0057] In the embodiment of the present disclosure, the control device 203 may 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 .

[0058] 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 acquired 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 gender and age of the user.

[0059] 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.

[0060] 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 comfortable temperature based on the ambient humidity and the ambient air flow rate, or predict the target comfortable 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 comfortable temperature to the microcontroller 2032, wherein the target comfortable 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 The thermal comfort evaluation index PMV (predicted mean perceived temperature) determines the user's optimal preferred temperature, takes the PMV value of 0 as the optimal comfort point, and the temperature point corresponding to the optimal comfort point as the user's optimal preferred temperature.

[0061] Specifically, 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, Artificial Neural Network) to obtain the target comfort temperature (°C) of the target object.

[0062] Figure 4 It is a structural diagram of an artificial neural network model according to an example.

[0063] refer 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 and air flow rate of the environment, 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.

[0064] In the disclosed embodiment, 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 data set, and the thermal comfort data set includes comfort levels corresponding to different ages, different genders, different temperatures, different humidities, 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.

[0065] In the disclosed embodiment, the training process of the artificial neural network model may include: obtaining multiple groups of training data, each group of training data includes user age, user gender, humidity, air flow rate and target temperature, wherein the target temperature refers to the temperature that makes the comfort level highest when the user age, user gender, humidity and air flow rate are determined; using the target temperature in each group of training data as a training label, inputting the user age, user gender, humidity and air flow rate in each group 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.

[0066] 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.

[0067] refer to Figure 3 When the current temperature of the smart textile 100 is lower than the target comfort temperature, the control device 203 is used to increase the power supply of the power supply device 201, so that the heat generation of the first conductive yarn 101 increases, so as to increase 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 used to decrease the power supply of the power supply device 201, so that the heat generation of the first conductive yarn 101 decreases, so as to reduce the current temperature of the smart textile 100.

[0068] Specifically, the computer 2033 can compare the current temperature of the smart textile 100 collected by the temperature sensor 107 and 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 increases, 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 decreases, thereby reducing the temperature of the smart textile 100.

[0069] The intelligent 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, which can avoid safety problems caused by excessive temperature and improve the reliability of the textile; at the same time, it can avoid waste of resources due to excessive temperature and save energy.

[0070] Figure 5 is a schematic diagram showing the relationship between ambient relative humidity, air flow rate, predicted temperature and actual temperature of textiles according to an example.

[0071] In the embodiment of the present disclosure, the user's age input into the artificial neural network model is 20 years old and the gender is female. Figure 5 It can be seen that the relative humidity remained basically unchanged during the test, and the predicted temperature (℃) increased moderately with the gradual increase of air speed (m / s). The patterns of the curves of the predicted temperature (℃) and the actual temperature (℃) were different from those of the curves of the predicted temperature (℃) to the actual temperature (℃) within 0 to 14 seconds; the fluctuations of the curves of the air speed (m / s), predicted temperature (℃) and actual temperature (℃) were roughly the same within 14 to 37 seconds. This indicates that the prediction model has a high correlation with the actual temperature of the fabric after 14 seconds, that is, the artificial intelligence system reaches stability within 14 seconds after power-on.

[0072] Figure 6 is a schematic diagram of a smart textile in a light environment and a dark environment according to an example.

[0073] refer 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. Due to the 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 a light environment and a dark environment, that is, the visualization effect can adapt to any lighting conditions to intuitively indicate the temperature of the smart textile.
