Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flexible sensing fabric, in particular to an integrated electromagnetic induction fabric and a preparation method thereof. BACKGROUND

[0002] At present, flexible sensing technology is developing rapidly and gradually applied to personal health monitoring, human-computer interaction and soft robot fields. However, this technology needs to be matched with external energy supply / storage devices (such as batteries), which limits its use range, service life and lightweight development. Therefore, self-energy supply of flexible sensing equipment is very critical.

[0003] The electromagnetic induction phenomenon refers to the phenomenon that the induced electromotive force occurs when the magnetic flux through the closed loop changes. This phenomenon was first discovered by Faraday, and self-generating devices based on electromagnetic induction have been gradually introduced, and have gradually become an important energy collection device. However, in the existing self-generating devices, the conductive coil and the magnet are mostly made of hard materials and are heavy, so they are not flexible and elastic, and thus it is difficult to combine them with flexible sensor devices.

[0004] In addition, the existing flexible sensor devices based on the electromagnetic induction phenomenon are mostly designed in a split type. For example, the patent with publication number CN111636130A provides a swing electromagnetic induction type power generation flexible fabric and its production method and application. The patent sets the magnetic yarn fabric and the conductive coil fabric on the surfaces of two opposite swing parts respectively, so as to convert the mechanical energy generated in the human body swing / walking process into electrical energy by using the electromagnetic induction effect of the human body. However, the magnetic fabric and the conductive coil fabric formed in this way are separated from each other, and can only be applied to two different surfaces that exist relative swing, so the actual application scenarios are limited.

[0005] Therefore, it is necessary to design an improved integrated electromagnetic induction fabric and a preparation method thereof to solve the above problems. SUMMARY

[0006] In view of the defects of the prior art, the purpose of the present application is to provide an integrated electromagnetic induction fabric and a preparation method thereof. The present application prepares a magnetic fiber with elasticity, and uses the magnetic fiber and the conductive fiber as weft yarn and the ordinary fiber as warp yarn for weaving, so that the magnetic fiber is arranged between the two conductive layers formed by the conductive fiber and the ordinary fiber along the weft direction, thereby realizing the integration of the magnetic fiber and the conductive fiber. The conductive fiber generates an induced electromotive force through stretching, patting, twisting, folding and other treatments of the fabric, and realizes the self-energy supply of the flexible sensing fabric.

[0007] To achieve the above purpose, the present application provides a preparation method of an integrated electromagnetic induction fabric, comprising the following steps:

[0008] S1, the pre-processed elastic polymer and magnetic particles are mixed according to a predetermined ratio, and then extruded, shaped and magnetized to obtain the magnetic fiber;

[0009] S2, the single conductive fiber is used as weft yarn and the ordinary fiber is used as warp yarn to weave the conductive layer;

[0010] S3, the magnetic fiber is arranged between the two conductive layers along the weft direction to obtain the integrated electromagnetic induction fabric.

[0011] As a further improvement of the present application, in step S1, the pre-treatment of the elastic polymer is to dissolve the elastic polymer pellets in a solvent; the mass ratio of the elastic polymer to the magnetic particles is 80:20-20:80.

[0012] As a further improvement of the present application, in step S1, the magnetization treatment is to magnetize the shaped fiber to be magnetized under a voltage of 1500-3000V for 1-2000ms to obtain the magnetic fiber.

[0013] As a further improvement of the present application, in step S1, the diameter of the magnetic fiber is 1-10mm.

[0014] As a further improvement of the present application, in step S2, in the conductive layer, the warp yarn density is 20-100 per 10cm, and the weft yarn density is 20-100 per 10cm.

[0015] As a further improvement of the present application, in step S3, in the integrated electromagnetic induction fabric, the arrangement density of the magnetic fiber is 1-30 per 10cm.

[0016] As a further improvement of the present application, in step S1, the elastic polymer includes any one of polyvinyl alcohol, polyurethane, polydimethylsiloxane, polymethylvinylsiloxane, polypropylene, polyolefin and styrene polymer.

[0017] As a further improvement of the present application, in step S1, the magnetic particles include any one of neodymium iron boron magnetic powder, neodymium nickel cobalt magnetic powder, iron oxide magnetic powder, chromium dioxide magnetic powder and cobalt-iron oxide magnetic powder.

[0018] As a further improvement of the present application, in step S2, the conductive fiber includes any one of carbon fiber, graphene fiber, carbon nanotube fiber, silver-plated fiber, copper-plated fiber, gold-plated fiber, aluminum-plated fiber, iron-plated fiber, copper fiber, silver fiber, gold fiber, aluminum fiber and iron fiber; the ordinary fiber includes any one of cotton fiber, wool fiber, polyester fiber and nylon fiber.

[0019] The application further provides an integrated electromagnetic induction fabric prepared by any of the above technical solutions, comprising a first conductive layer, a second conductive layer and a plurality of magnetic fibers arranged along the weft between the first conductive layer and the second conductive layer; the first conductive layer and the second conductive layer are consistent in structure.

[0020] The application has the following advantages:

[0021] 1. The integrated electromagnetic induction fabric provided by the application is prepared by mixing elastic polymers and magnetic particles to prepare magnetic fibers with elasticity, using the magnetic fibers and conductive fibers as weft yarns, using common fibers as warp yarns, and weaving according to a set structure, so that the magnetic fibers are arranged along the weft between the two conductive layers formed by the interweaving of the conductive fibers and the common fibers, realizing the integration of the magnetic fibers and the conductive fibers. Based on the structure of the integrated electromagnetic induction fabric, the conductive fibers generate induced electromotive force through stretching, patting, twisting, folding and other treatments of the fabric, realizing self-power supply of the flexible sensing fabric.

[0022] 2. On the one hand, the application fully enhances the magnetism of the magnetic fibers through magnetization treatment, improving the magnetic induction intensity of the fabric; on the other hand, by reasonably designing the composition of the magnetic fibers and the structure of the fabric, the magnetic fibers with elasticity are located in the hole structure formed by the two conductive layers, and after stretching the fabric along the warp direction, the magnetic fibers deform and displace, and at the same time, the conductive fibers cut the magnetic induction lines along the stretching direction of the fabric, so that the integrated electromagnetic induction fabric prepared by the application can generate sufficient electrical signal changes when deforming, so as to be used for sensing and monitoring and improve the sensitivity of monitoring.

[0023] 3. The integrated electromagnetic induction fabric provided by the application integrates the conductive fibers and the magnetic fibers, and by arranging the magnetic fibers between the two parallel conductive layers, the magnetic fibers can deform only by stretching the fabric, without directly stretching the magnetic fibers, so that the service life of the magnetic fibers can be prolonged; at the same time, the conductive layer arranged on the outside can also protect the magnetic fibers, further slowing down the wear of the magnetic fibers, so as to protect the elasticity and magnetic induction intensity of the magnetic fibers; and the magnetic fibers can also be disassembled and replaced as needed, effectively prolonging the service life of the fabric.

[0024] 4. The integrated electromagnetic induction fabric provided by the application integrates power supply and sensing on the fabric and clothing, and utilizes the flexibility of common fibers and the elasticity of magnetic fibers, so that it can be arbitrarily bent and rebounded, is convenient for human wearing, and does not need to use external power supply equipment such as batteries, but can generate electrical signals through the action and external force of the human body, so that it has a wide application prospect.

[0035] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in detail below with reference to the accompanying drawings and specific examples.

[0036] Here, it should also be noted that, in order to avoid the present application being obscured by unnecessary details, only the structures and / or processing steps closely related to the solutions of the present application are shown in the accompanying drawings, and other details not closely related to the present application are omitted.

[0037] In addition, it should also be noted that the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such a process, method, article or device.

[0038] The present application provides a preparation method of an integrated electromagnetic induction fabric, comprising the following steps:

[0039] S1, the pre-processed elastic polymer and magnetic particles are mixed in a predetermined ratio, and then extruded, shaped and magnetized to obtain magnetic fibers;

[0040] S2, a single conductive fiber is used as weft yarn, and ordinary fibers are used as warp yarn to weave a conductive layer;

[0041] S3, a plurality of magnetic fibers are arranged between the two conductive layers along the weft direction to obtain an integrated electromagnetic induction fabric.

[0042] In the above manner, the magnetic fibers obtained in step S1 have good elasticity and high magnetic induction strength. On this basis, by arranging the magnetic fibers between the two conductive layers and connecting the conductive fibers in the two conductive layers in series to form a closed circuit, the conductive fibers and the magnetic fibers are integrated, and by stretching, patting, twisting, folding and other treatments of the fabric, the elasticity of the magnetic fibers is utilized to deform and displace the magnetic fibers, the conductive fibers are cut to move along the magnetic induction lines, an induced electromotive force is generated, and the flexible sensing fabric is self-powered.

[0043] More preferably, the conductive layer specifically includes a conductive region and a non-conductive region. In the conductive region, a conductive fiber is interwoven with ordinary fibers as warp yarn along the weft direction in an S shape. In the non-conductive region, ordinary fibers are interwoven in the warp and weft directions. The non-conductive region is located outside the conductive region, which facilitates connection with other fabrics or garments as a connecting part, and stretching of the fabric by hand without direct stretching of the magnetic fibers, which is conducive to protecting the elasticity and magnetic induction strength of the magnetic fibers and prolonging the service life of the magnetic fibers.

[0044] In the preparation process of the fabric, the two conductive layers are combined in a mutually overlapping manner, and the upper and lower conductive layers are fixed at intervals to form a plurality of holes between the two conductive layers for the magnetic fibers to extend along the weft direction of the fabric. In this way, the magnetic fibers can be fixed between the two conductive layers, the integration of the magnetic fibers and the conductive fibers is achieved, the magnetic fibers are protected by the external conductive layer, and the magnetic fibers can be easily disassembled and replaced as needed, effectively prolonging the service life of the fabric.

[0045] More specifically, in step S1, the purpose of the pre-treatment operation of the elastic polymer is to form a liquid phase capable of being uniformly mixed with the magnetic particles, and the specific pre-treatment method includes dissolving the elastic polymer pellets in a solvent or preparing a polymer solution by mixing a base agent with a curing agent; the selection of the solvent, the base agent and the curing agent is determined according to the type of the elastic polymer, and the elastic polymer can be mixed with the magnetic particles to form a liquid phase, and the present application does not limit this. The shaping treatment method in step S1 can also be freely selected according to the type of the elastic polymer, and the polymer can be cured and shaped.

[0046] In step S1, the mass ratio of the elastic polymer to the magnetic particles is 80:20-20:80; the magnetization treatment is to magnetize the shaped fiber to be magnetized under a voltage of 1500-3000V for 1-2000ms to obtain the magnetic fiber. In this way, the magnetic fiber prepared can have good elasticity and high magnetic induction strength.

[0047] More specifically, in step S1, the diameter of the magnetic fiber is 1-10mm. In this way, it can be matched with the size of the fabric to ensure that the magnetic particles can be uniformly and effectively distributed in the fabric, while considering flexibility and lightness. If the magnetic fiber is too fine, the content of the magnetic particles is too small, and the strength of the magnetic field generated is insufficient; if the magnetic fiber is too thick, the mass is too heavy, which affects the weaving and hand feeling of the fabric.

[0048] In step S2, in the conductive layer, the warp density is 20-100 roots / 10cm, and the weft density is 20-100 roots / 10cm. The limitation of the warp density can effectively fix the relative position of the magnetic fiber and the wire, and ensure that the wire can respond to the deformation and relative displacement of the magnetic fiber with high efficiency during the process of beating, pressing, etc., to generate a stronger sensing signal. The limitation of the weft density can optimize the density of the wire while ensuring the flexibility and lightness of the fabric, thereby ensuring the strength of the sensing signal.

[0049] In step S3, in the integrated electromagnetic induction fabric, the arrangement density of the magnetic fiber is 1-30 roots / 10cm. Adjusting the arrangement density within this range can control the strength of the sensing signal and the weight and flexibility of the fabric, so that the fabric can be applied to more diversified scenarios.

[0050] Preferably, the elastic polymer comprises any one of polyvinyl alcohol, polyurethane, polydimethylsiloxane, polymethylvinylsiloxane, polypropylene, polyolefin and styrene polymer; the magnetic particle comprises any one of neodymium iron boron magnetic powder, neodymium nickel cobalt magnetic powder, iron oxide magnetic powder, chromium dioxide magnetic powder and cobalt-iron oxide magnetic powder. The conductive fiber comprises any one of carbon fiber, graphene fiber, carbon nanotube fiber, silver-plated fiber, copper-plated fiber, gold-plated fiber, aluminum-plated fiber, iron-plated fiber, copper fiber, silver fiber, gold fiber, aluminum fiber and iron fiber; the common fiber comprises any one of cotton fiber, wool fiber, polyester fiber and nylon fiber.

[0051] The application further provides an integrated electromagnetic induction fabric prepared by the above technical solution, a structural diagram of which is shown in the figure. Figures 1-3 The integrated electromagnetic induction fabric comprises a first conductive layer 10, a second conductive layer 30 and a plurality of magnetic fibers 20 arranged along the weft direction between the first conductive layer 10 and the second conductive layer 30; the first conductive layer 10 and the second conductive layer 30 are consistent in structure and are both knitted by conductive fibers 11 as weft yarns and common fibers 12 as warp yarns.

[0052] The integrated electromagnetic induction fabric and the preparation method thereof provided by the application will be described below in combination with specific examples.

[0053] Example 1

[0054] The application provides a preparation method of an integrated electromagnetic induction fabric, which comprises the following steps:

[0055] S1, according to the description in the instruction manual, mix solution A and B in a mass ratio of 10:1 to obtain uncured polydimethylsiloxane silicone elastomer, and add neodymium iron boron magnetic powder, extrude through a syringe needle tube, dry at 80℃ for 2 hours for curing and shaping treatment, magnetize the fiber to be magnetized after curing and shaping under a voltage of 2000V for 20ms to obtain magnetic fibers with a diameter of 5mm; wherein the mass ratio of polydimethylsiloxane to neodymium iron boron magnetic powder is 20:80.

[0056] S2, use a single conductive fiber (copper fiber with a diameter of 0.1mm) as weft yarn and common fiber with a diameter of 0.1mm as warp yarn to knit a conductive layer; in the conductive layer, the warp yarn density is 60 roots / 10cm and the weft yarn density is 60 roots / 10cm.

[0057] S3, arrange the magnetic fibers along the weft direction between the two layers of conductive layers at a preset arrangement density of 10 roots / 10cm to obtain an integrated electromagnetic induction fabric.

[0058] Comparative Examples 1-3

[0059] Comparative Examples 1-3 respectively provide a preparation method of an integrated electromagnetic induction fabric. Compared with Example 1, Comparative Example 1 does not perform the magnetization treatment operation in step S1, Comparative Example 2 directly winds the copper fiber around the magnetic fiber to form a closed loop (the structure diagram is shown in Figure 4 ), and Comparative Example 3 weaves the conductive fiber as the warp and the magnetic fiber as the weft (the structure diagram is shown in Figure 5 ). The remaining steps are consistent with Example 1 and will not be repeated here.

[0060] The voltage change of the integrated electromagnetic induction fabric prepared by Example 1 and Comparative Examples 1-2 with deformation is detected, and the detection result is shown in Figures 6-8 . The detection result shows that compared with the fabric without magnetization, the voltage change signal of the fabric after magnetization is expanded by one order of magnitude, and the magnetization treatment can significantly enhance the voltage signal strength, which is convenient for the detection, output and analysis of the rear-end signal. Compared with the simple winding series method in Comparative Example 2, the fabric organizational structure design of Example 1 can realize strong signal monitoring of multiple actions, and has significant superiority in capturing the signal of beating and bending action, so that it can adapt to more diverse application scenarios.

[0061] The wear resistance and friction pilling test of the integrated electromagnetic induction fabric prepared by Example 1 and Comparative Example 3 is carried out, and the test results are shown in Table 1, and Table 2 is the rating explanation. The detection result shows that the wear resistance of the fabric prepared by Example 1 is significantly better than that of Comparative Example 3, and the fabric morphology is still intact after 500 times of friction. This is because the organizational structure of Example 1 is tight, which can effectively prevent the structure from loosening due to friction and displacement. At the same time, the weaving structure of the commonly used fiber completely covers the side surface of the magnetic fiber, so that the magnetic fiber will not be directly worn and torn, prolonging the effective service life of the fabric and providing a guarantee for the practical application of the integrated electromagnetic induction fabric.

[0066] Examples 2-5

[0067] Embodiments 2-5 respectively provide a preparation method of the integrated electromagnetic induction fabric. Compared with Embodiment 1, in Embodiment 2, only the mass ratio of polydimethylsiloxane to neodymium-iron-boron magnetic powder is adjusted to 50:50, in Embodiment 3, only the mass ratio of polydimethylsiloxane to neodymium-iron-boron magnetic powder is adjusted to 80:20, in Embodiment 4, only the warp density and weft density distribution in the conductive layer is adjusted to 30 / 10 cm and 40 / 10 cm, and in Embodiment 5, only the arrangement density of the magnetic fibers in the fabric is adjusted to 5 / 10 cm, and the remaining steps are consistent with Embodiment 1, which will not be repeated here.

[0068] It is tested that the integrated electromagnetic induction fabrics prepared in Embodiments 2-5 can all generate relatively strong voltage changes with shape changes. Compared with Embodiment 1, due to the reduction of the content of magnetic particles, the magnetic field intensity generated by the magnetic fibers is reduced, and the electromagnetic induction electromotive force generated by the action trigger fabric is reduced, and the voltage signal intensity of Embodiments 2 and 3 shows a gradually decreasing trend. In Embodiment 4, the voltage change intensity is smaller than that of Embodiment 1. According to the electromagnetic induction law E = nBLv, the reduction of the weft density (i.e. the reduction of n) will directly affect the induced electromotive force. At the same time, the reduction of the warp density makes the fixed positions of the conductive fibers and the magnetic fibers in the fabric structure relatively loose, which reduces the effective power generation efficiency when the two relatively displace, and also affects the voltage size. Embodiment 5 reduces the arrangement density of the magnetic fibers, which directly causes the reduction of the magnetic field intensity, so the voltage change signal is obviously reduced.

[0069] In summary, the present application provides an integrated electromagnetic induction fabric and a preparation method thereof. The present application mixes the elastic polymer and the magnetic particles in a predetermined ratio, and then performs extrusion, shaping and magnetization treatment in sequence to prepare the magnetic fibers. Then, the magnetic fibers and the conductive fibers are used as weft, and the ordinary fibers are used as warp, and the fabric is woven according to the set structure, so that the magnetic fibers are arranged along the weft between the two conductive layers formed by the interweaving of the conductive fibers and the ordinary fibers, the integration of the magnetic fibers and the conductive fibers is realized, and the integrated electromagnetic induction fabric is obtained. The integrated electromagnetic induction fabric prepared by the above-mentioned method can generate an induced electromotive force after being subjected to stretching, patting, twisting, folding and other treatments, realizes self-power supply of the flexible sensing fabric, and can generate sufficient electrical signal changes by human action or external force without the need for external power supply equipment, so as to be used for sensing and monitoring.

[0070] The above embodiments are only used to illustrate the technical solutions of the present application rather than limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
