Description

Technical Field

[0001] This invention relates to the field of flexible electronic materials and their fabrication technology, specifically to colored pulsed fabric electrodes, their fabrication methods, and their applications. Background Technology

[0002] In the field of medical rehabilitation, pulse therapy devices have become common physical therapy equipment. The performance of their core component—the pulse electrode—directly affects the treatment effect and the patient's experience. Compared with traditional rigid metal electrodes and conductive film electrodes, fabric electrodes, due to their excellent flexibility, breathability, comfort, and skin compatibility, can closely fit the complex curves of the human body, effectively reducing discomfort caused by prolonged treatment, and are gradually becoming the mainstream development direction for pulse therapy device electrodes. However, existing conductive fabrics are generally black or metallic in color, and research has generally neglected the need for colored electrodes.

[0003] Therefore, developing a method for preparing pulse fabric electrodes that combines excellent water resistance, electrical stability, comfortable skin feel, and colorful appearance is of urgent practical significance for improving the user experience and clinical applicability of pulse therapy devices. Summary of the Invention

[0004] In view of this, the technical problem to be solved by the present invention is to provide a colored pulse fabric electrode, its preparation method and application. The colored pulse fabric electrode obtained by the method provided by the present invention not only has uniform color, but also has high water washability and stable conductivity.

[0005] A first aspect of the present invention provides a colored pulsed fabric electrode, comprising a fabric body having a plain weave structure formed by multiple warp yarns and multiple weft yarns interwoven together, wherein the warp yarns and weft yarns independently comprise colored cellulose fiber yarns and metal-plated yarns with a cross-linked film on their surface; the cross-linked film comprises copper powder, an antioxidant, a polymer, and a cross-linking agent; in the multiple warp yarns, each colored cellulose fiber yarn is spaced apart by one metal-plated yarn with a cross-linked film on its surface; in the multiple weft yarns, each colored cellulose fiber yarn is spaced apart by one metal-plated yarn with a cross-linked film on its surface.

[0006] In the colored pulse fabric electrode provided by the first aspect of the present invention, the crosslinking film comprises copper powder, an antioxidant, a polymer, and a crosslinking agent. Preferably, the polymer is selected from one or more of PVA or polyurethane. Preferably, the polymer is selected from polymers with a degree of hydrolysis ≥99%. Preferably, the polymer is selected from one or more of type 2099 PVA or polyurethane. More preferably, by mass fraction, the polymer comprises 0.1%~0.3% copper powder, 0.1%~2% antioxidant, 2%~7% PVA with a degree of hydrolysis ≥99%, and 3%~15% crosslinking agent. Even more preferably, by mass fraction, the polymer comprises 0.1%~0.3% copper powder, 2.5%~3.5% antioxidant, 4%~7% type 2099 PVA, and 3%~15% crosslinking agent. The colored pulse fabric electrode provided in the first aspect of the present invention is based on a cross-linked film on the surface of a metal-plated yarn, which not only has uniform color but also high water resistance and stable conductivity.

[0007] In the colored pulse fabric electrode provided by the first aspect of the present invention, the warp and weft yarns independently include colored cellulose fiber yarns and metal-plated yarns with cross-linked films on their surfaces. That is, colored cellulose fiber yarns and metal-plated yarns with cross-linked films on their surfaces are used as warp yarns, and colored cellulose fiber yarns and metal-plated yarns with cross-linked films on their surfaces are used as weft yarns.

[0008] In the colored pulse fabric electrode provided by the first aspect of the present invention, the metal-plated yarn with a cross-linked film on its surface specifically includes a base yarn, a metal plating layer disposed on the surface of the base yarn, and a cross-linked film disposed on the surface of the metal plating layer. The cross-linked film is a polymer cross-linked film; the base yarn is selected from polyester fiber yarn, polyamide fiber yarn, or cotton fiber yarn; and the metal plating layer is selected from one or more mixed plating layers selected from silver plating, copper plating, and nickel plating.

[0009] More specifically, the thickness of the cross-linked film in the metal-coated yarn with a cross-linked film on the surface described in this invention is 0.1 μm to 5 μm. The yarn count of the conductive metal-coated yarn in the metal-coated yarn with a cross-linked film on the surface described in this invention is 40D to 200D; the line resistance of the conductive metal-coated yarn is ≤10 Ω / cm.

[0010] In the colored pulse fabric electrode provided by the first aspect of the present invention, the colored cellulose fiber yarn is selected from a blend of one or more fibers selected from Tencel yarn, cotton yarn, bamboo fiber, viscose fiber, linen yarn, and Lyocell yarn; the yarn count of the colored cellulose fiber yarn is 60S to 100S; and the moisture regain of the cellulose fiber yarn is 8% to 12%. Cellulose fibers possess the functions of moisture absorption, breathability, providing a soft touch, and carrying dyes. When interwoven with conductive yarns, they can significantly improve the overall comfort of the fabric electrode.

[0011] Specifically, the colored cellulose fiber yarn of this invention is obtained by dyeing cellulose fiber yarn, and more specifically by dyeing and finishing cellulose fiber yarn. The dyeing is performed using a dyeing solution with a liquid content of 63%–68%, comprising a dye concentration of 1 g / L–50 g / L and a fixing alkali concentration of 10 g / L–50 g / L. The dye is selected based on the target color using a cold-dyeing reactive dye. Precise dyeing using this cold-dyeing reactive dye allows for the fabrication of colored pulse fabric electrodes, meeting the aesthetic requirements of flexible electronic devices. Specifically, the cold-dyeing reactive dye is a vinyl sulfone type or a dual-reactive-group reactive dye. The cross-linked film on the metal-plated conductive yarn in the fabric base of this invention forms a selective permeation barrier, ensuring that the dye acts only on the cellulose fiber yarn and does not penetrate to the metal plating surface, thus ensuring stable line resistance of the conductive yarn after dyeing. The finishing process uses a softener with a liquid content of 70%–75%. In some embodiments of this invention, the softener is preferably a non-silicone softener, more preferably a biodegradable non-silicone softener.

[0012] The colored pulse fabric electrode provided in the first aspect of this invention has a plain weave structure formed by multiple warp and weft yarns interlacing together. The plain weave structure, with each cellulose fiber yarn spaced between a metal-plated yarn with a cross-linked film on its surface, has numerous interlacing points, a tight structure, and good stability. The colored pulse fabric electrode provided in the first aspect of this invention, through the hydrophobic barrier effect of the cross-linked film on the surface of the metal-plated yarn, combined with the specific weaving structure of the colored cellulose fiber yarns, results in a conductive fabric that is not only uniformly colored but also has high washability and stable conductivity.

[0013] A second aspect of the present invention provides a colored pulsed fabric electrode, comprising a fabric body including a front layer and an inner layer joined together; the front layer and the inner layer independently have a plain weave structure formed by multiple warp yarns and multiple weft yarns interwoven with each other, wherein the warp yarns and weft yarns independently include colored cellulose fiber yarns and metal-plated yarns with a cross-linked film on their surface; the cross-linked film includes copper powder, an antioxidant, a polymer, and a cross-linking agent; in the multiple warp yarns, each colored cellulose fiber yarn is spaced apart by one metal-plated yarn with a cross-linked film on its surface; in the multiple weft yarns, each colored cellulose fiber yarn is spaced apart by one metal-plated yarn with a cross-linked film on its surface.

[0014] In the colored pulse fabric electrode provided in the second aspect of the present invention, the warp and weft yarns independently comprise colored cellulose fiber yarns and metal-plated yarns with a cross-linked film on their surfaces. That is, colored cellulose fiber yarns and metal-plated yarns with a cross-linked film on their surfaces are used as warp yarns, and colored cellulose fiber yarns and metal-plated yarns with a cross-linked film on their surfaces are used as weft yarns. The colored cellulose fiber yarns and metal-plated yarns with a cross-linked film on their surfaces are the same as described above and will not be repeated here.

[0015] In the color pulse fabric electrode provided by the second aspect of the present invention, the main body of the fabric includes a front layer and an inner layer that are joined together. Specifically, the joining method of the present invention is an "upper-to-lower" joining method, which achieves structural integration through the interlacing of the front warp (referred to as the upper warp yarn or surface warp) and the inner weft (referred to as the lower weft yarn or inner weft). More specifically, the joining method is a fabric weaving cycle method in which the warp yarn of the surface layer sinks at a set joining point position and interlaces with the weft yarn of the inner layer to form a joining structure connecting the surface layer and the inner layer; each weaving cycle is provided with 2 joining points to ensure that the two layers are stably bonded without affecting the flatness of the fabric. More specifically, the joining method is a fabric weaving pattern in which the warp yarns of the outer layer sink once to interweave with the weft yarns of the inner layer every three warp yarns of the outer layer, forming a joining structure connecting the outer layer and the inner layer. In addition, every three warp yarns of the outer layer, one warp yarn of the outer layer sinks once to interweave with the weft yarns of the inner layer, forming a joining structure connecting the outer layer and the inner layer.

[0016] In the colored pulse fabric electrode provided by the second aspect of the present invention, the cross-linking film is the same as that provided by the colored pulse fabric electrode in the first aspect, and will not be described again. In the colored pulse fabric electrode provided by the second aspect of the present invention, on the one hand, based on the cross-linking film on the surface of the metal-coated yarn, it not only has uniform color but also high water resistance and stable conductivity; on the other hand, based on the fact that the outer and inner layers of the fabric body independently have a plain weave structure formed by multiple warp yarns and multiple weft yarns interwoven together, and each cellulose fiber yarn is separated by one metal-coated yarn with a cross-linking film on its surface, the plain weave double-layer bonding structure not only has many interlacing points, a tight structure, and good stability, but also allows the metal-coated yarn with the cross-linking film on its surface and the colored cellulose fiber yarn to be spatially alternately arranged, with a constant spacing between the conductive points of the conductive yarns, ensuring uniform current density, establishing a continuous and stable conductive network, and ensuring stable fabric surface resistance. The colored pulse fabric electrode provided in the second aspect of the present invention, through the hydrophobic barrier effect of the cross-linked film on the surface of the metal-plated yarn, combined with the specific weaving structure of the colored cellulose fiber yarn, results in a conductive fabric that is not only uniform in color, but also has high water washability and stable conductivity.

[0017] The colored pulsed fabric electrodes provided in the first and second aspects of this invention have a point resistance of <0.5Ω / cm, a point resistance of <0.6Ω / cm after 20 washes, an air permeability of >500 mm / s, and a tensile strength of >350N. The colored pulsed fabric electrodes provided in the first and second aspects of this invention meet the diverse aesthetic requirements of flexible electronic devices.

[0018] The colored pulse fabric electrode provided in both the first and second aspects of this invention further includes a conductive connection portion disposed on the fabric body. Specifically, the conductive connection portion is a conductive buckle, conductive snap, or conductive fabric strip sewn or riveted to the fabric body. The conductive connection portion of this invention can be used to connect core components of medical products. In some embodiments of this invention, the conductive connection portion is used to connect a pulse generator.

[0019] This invention also provides a method for preparing a colored pulsed fabric electrode, comprising the following steps:

[0020] S1) The metal-plated conductive yarn is treated with a treatment solution and cured to obtain the treated metal-plated conductive yarn.

[0021] The treatment solution comprises: copper powder, antioxidant, polymer, crosslinking agent and water;

[0022] S2) The treated metal-plated conductive yarn and cellulose fiber yarn obtained in step S1) are used as warp and weft yarns, and are woven in a plain weave with one treated metal-plated yarn every other cellulose fiber yarn to obtain the fabric base.

[0023] S3) Dye the fabric base obtained in step S2), and then perform post-treatment to obtain a colored pulse fabric electrode.

[0024] The method for preparing a colored pulsed fabric electrode provided by this invention uses a metal-plated conductive yarn as the base yarn. After forming a cross-linked film on its surface to construct a hydrophobic barrier, a specific weave is performed to achieve differentiated dyeing and color development of the conductive fabric. The resulting conductive fabric not only has uniform color but also high washability and stable conductivity. The cross-linked film formed by this invention is the same as the cross-linked film described in the colored pulsed fabric electrodes provided in the first and second aspects above, and will not be repeated here.

[0025] This invention first treats a metal-plated conductive yarn with a treatment solution to form a cross-linked film on the surface of the yarn, thereby constructing a hydrophobic barrier. The polymer in the treatment solution is selected from one or more of PVA or polyurethane. Preferably, the polymer is selected from a polymer with a degree of hydrolysis ≥99%. More preferably, the polymer is selected from one or more of type 2099 PVA or polyurethane. More preferably, by mass fraction, the treatment solution comprises: 0.1%~0.3% copper powder, 0.1%~2% antioxidant, 2%~7% PVA with a degree of hydrolysis ≥99%, 3%~15% cross-linking agent, and the balance being water. Even more preferably, by mass fraction, the treatment solution comprises: 0.1%~0.3% copper powder, 0.1%~2% antioxidant, 2%~7% type 2099 PVA, 3%~15% cross-linking agent, and the balance being water.

[0026] This invention treats the metal-coated conductive yarn with a processing solution, specifically by: impregnating the metal-coated conductive yarn with individual yarns; the impregnation speed is 30 m / min to 100 m / min; the impregnation tension is 250 N to 350 N. More specifically, the metal-coated conductive yarn is dried after impregnation; the drying temperature is 60℃ to 100℃. The metal-coated conductive yarn of this invention is selected from one or more of silver-plated polyester yarn, silver-plated nylon yarn, silver-plated aramid yarn, copper-plated nylon yarn, and nickel-silver composite nylon yarn; the yarn count of the metal-coated conductive yarn is 40D to 200D; the line resistance of the metal-coated conductive yarn is ≤10 Ω / cm.

[0027] This invention involves treating a metal-plated conductive yarn with a treatment solution followed by curing to obtain the treated metal-plated conductive yarn. The curing temperature is 120℃~180℃, and the curing time is 1 min~8 min. The curing process enables the treatment solution impregnated on the surface of the metal-plated conductive yarn to form a continuous and dense cross-linked film without affecting the yarn's conductivity.

[0028] After obtaining the treated metal-plated conductive yarn, this invention uses the treated metal-plated conductive yarn and cellulose fiber yarn as warp and weft yarns, respectively, and weaves them in a plain weave pattern with one treated metal-plated yarn every other cellulose fiber yarn to obtain a fabric base. Specifically, the treated metal-plated conductive yarn and cellulose fiber yarn are used as warp yarns, and the treated metal-plated conductive yarn and cellulose fiber yarn are used as weft yarns, woven in a plain weave pattern with one treated metal-plated yarn every other cellulose fiber yarn to obtain a fabric base. The weaving speed of this invention is 400 r / min to 600 r / min; the warp tension is 15 cN / yarn to 25 cN / yarn; and the weft tension is 15 cN / yarn to 25 cN / yarn. In some embodiments of this invention, the weaving is performed using an air-jet loom.

[0029] Preferably, in this invention, the obtained treated metal-plated conductive yarn and cellulose fiber yarn are used as warp and weft yarns, respectively. A double-layer fabric base is obtained by weaving in a plain weave pattern with one treated metal-plated yarn between each cellulose fiber yarn. The double-layer weaving described in this invention is an "upper-to-lower" weaving, where the structure is integrated through the interlacing of the outer warp (referred to as the upper warp or surface warp) and the inner weft (referred to as the lower weft or inner weft), ensuring a stable bond between the two layers without affecting the fabric's smoothness. More specifically, the double-layer weaving involves a cyclic weaving pattern where the surface warp yarns sink at designated weaving points and interlace with the inner weft yarns to form a connecting structure between the surface and inner layers. Two weaving points are set within each weaving cycle to ensure a stable bond between the two layers without affecting the fabric's smoothness. More specifically, the double-layer weaving is a cyclic weaving structure in which the warp yarns of the outer layer sink down once to interweave with the weft yarns of the inner layer every three warp yarns of the outer layer, and every three warp yarns of the outer layer, one warp yarn of the outer layer sinks down once to interweave with the weft yarns of the inner layer.

[0030] The speed, warp tension, weft tension, and weaving equipment used in the double-layer weaving described in this invention are the same as those in the aforementioned weaving, and will not be repeated here.

[0031] The cellulose fiber yarn described in this invention is the same as the cellulose fiber yarn described in the color pulse fabric electrode provided in the first and second aspects above, and will not be described again.

[0032] This invention produces a fabric base cloth woven in a plain weave with one treated metal-plated yarn between each cellulose fiber yarn. The plain weave has many interlacing points, a tight structure, and good stability. In particular, by splicing double-layer weaving, the treated metal-plated conductive yarn and the skin-friendly cellulose fiber yarn are arranged alternately in space. The spacing between the conductive points of the conductive yarns is constant, ensuring uniform current density and establishing a continuous and stable conductive network, thus ensuring stable fabric surface resistance.

[0033] After obtaining the fabric base, the present invention dyes the obtained fabric base. Specifically, the obtained fabric base is immersed in a dyeing solution with a liquid content of 63% to 68%, and then piled for dyeing at 25°C to 40°C for 8 to 12 hours. The dyeing solution described in the present invention is the same as the dyeing solution described in the color pulse fabric electrode provided in the first and second aspects above, and will not be described again.

[0034] The present invention dyes the obtained fabric base and then performs post-treatment on the dyed fabric base to obtain a colored pulse fabric electrode. Specifically, the dyed fabric base is impregnated with a softener at a liquid content of 70% to 75%; wherein the softener is the same as the softener described in the colored pulse fabric electrode provided in the first and second aspects above, and will not be described again.

[0035] The preparation method provided by this invention cleverly solves the multiple requirements of pulse fabric electrodes through a carefully designed and irreversible process sequence (yarn film formation → weaving → overall dyeing). A specific treatment solution is used to modify the surface of the metal-plated conductive yarn, forming a dense and stable cross-linked film structure on the yarn surface. This film serves as both a waterproof barrier, protecting conductivity, and a dyeing isolation layer, ensuring that the dye only colors the cellulose fibers and does not corrode the metal-plated conductive yarn. During weaving, the treated metal-plated conductive yarn and cellulose fiber yarn are interwoven in a plain weave with one treated metal-plated yarn between every one cellulose fiber yarn. This ensures stable fabric surface resistance and enhances the comfort of the pulse fabric electrode by leveraging the moisture-wicking and breathable properties of cellulose fibers. Finally, the selected reactive dyes for cold dyeing primarily form covalent bonds with the cellulose fibers, minimizing the impact on the conductive portion already encapsulated by the cross-linked film during the dyeing process. This achieves rich colors in the fabric without significantly sacrificing conductivity.

[0036] The present invention also provides a medical product comprising a core component and an electrode; the electrode is selected from any of the color pulse fabric electrodes described above or color pulse fabric electrodes obtained by any of the preparation methods described above. Preferably, the medical product is a low-frequency pulse, medium-frequency pulse, and medium-low frequency mixed pulse therapy device.

[0037] This invention provides a colored pulsed fabric electrode, its preparation method, and its applications. The preparation method includes a process flow of "matrix yarn pretreatment → water-wash resistance enhancement treatment → drying and curing → double-layer pulsed fabric electrode weaving → pulsed fabric electrode dyeing → finishing." Based on the technical principles of four core mechanisms—carefully designed and irreversible process sequence, material interface modification, textile structure optimization, and precise dyeing control—this invention achieves a synergistic improvement in performance and function, providing a colored pulsed fabric electrode that combines high reliability, high comfort, and high aesthetics. It can be dyed in a variety of colors, allowing the electrode to blend more naturally into everyday clothing or fashion designs, meeting aesthetic and concealment requirements. It not only has uniform color but also high water-wash resistance, stable conductivity, obvious effects, simple operation, and easy production control. It can be directly applied to clothing for low-frequency, medium-frequency, and medium-low frequency mixed pulsed therapy devices. Attached Figure Description

[0043] This invention discloses a colored pulsed fabric electrode, its preparation method, and its application. Those skilled in the art can refer to the content of this document and appropriately modify the process parameters to achieve the desired result. It should be particularly noted that all similar substitutions and modifications are obvious to those skilled in the art and are considered to be included in this invention. The methods and applications of this invention have been described through preferred embodiments, and those skilled in the art can clearly modify or appropriately change and combine the methods and applications described herein without departing from the content, spirit, and scope of this invention to realize and apply the technology of this invention.

[0044] A first aspect of the present invention provides a colored pulsed fabric electrode, comprising a fabric body having a plain weave structure formed by multiple warp yarns and multiple weft yarns interwoven together, wherein the warp and weft yarns independently comprise colored cellulose fiber yarns and metal-plated yarns with a cross-linked film on their surface; in the multiple warp yarns, each colored cellulose fiber yarn is spaced apart by one metal-plated yarn with a cross-linked film on its surface; the cross-linked film comprises copper powder, an antioxidant, a polymer, and a cross-linking agent; in the multiple weft yarns, each colored cellulose fiber yarn is spaced apart by one metal-plated yarn with a cross-linked film on its surface. Figure 1 As shown, Figure 1 This is a schematic diagram of a partial weft cross-sectional structure of the colored pulse fabric electrode provided in the first aspect of the present invention, where 101 is the warp yarn, and 201, 202, 203, and 204 are all weft yarns. The line thickness is for illustrative purposes only and does not reflect the actual thickness. Figure 2 As shown, Figure 2 This is a schematic diagram of a partial three-dimensional structure of a colored pulse fabric electrode provided in the first aspect of the present invention, wherein 101, 102, 103 and 104 are warp yarns, and 201, 202, 203 and 204 are weft yarns. The thickness of the lines is only for illustration and does not reflect the actual thickness.

[0045] A second aspect of the present invention provides a colored pulse fabric electrode, comprising a fabric body including a front layer and an inner layer connected by a bonding layer; the front layer and the inner layer independently have a plain weave structure formed by multiple warp yarns and multiple weft yarns interwoven with each other, wherein the warp yarns and weft yarns independently include colored cellulose fiber yarns and metal-plated yarns with a cross-linked film on their surface; the cross-linked film includes copper powder, an antioxidant, a polymer, and a cross-linking agent; among the multiple warp yarns, each colored cellulose fiber yarn is spaced apart by one metal-plated yarn with a cross-linked film on its surface; among the multiple weft yarns, each colored cellulose fiber yarn is spaced apart by one metal-plated yarn with a cross-linked film on its surface, wherein the bonding method is an "upper-to-lower" bonding method, specifically, the structure is integrated by interweaving the front warp (referred to as the upper layer warp or surface warp yarn) and the inner weft (referred to as the lower layer weft or inner layer weft yarn), with two bonding points set in each weave cycle to ensure stable bonding between the two layers without affecting the flatness of the fabric. More specifically, the joining method is a fabric weaving pattern in which the surface warp yarns sink once every three surface weft yarns to interweave with the inner weft yarns, forming a joining structure connecting the surface and inner layers. Furthermore, every three surface warp yarns, one surface warp yarn sinks once to interweave with the inner weft yarn, forming another joining structure connecting the surface and inner layers. For example... Figure 3 As shown, Figure 3This is a schematic diagram of a partial weft cross-sectional structure of the colored pulse fabric electrode provided in the second aspect of the present invention, wherein 111 is the inner warp yarn, 112 is the outer warp yarn, 211, 212, 213 and 214 are all inner weft yarns, 221, 222, 223 and 224 are all outer weft yarns, 301 is a knotting structure, and the line thickness is for illustrative purposes only and does not reflect the actual thickness.

The thickness of the lines is only for illustration and does not reflect the actual thickness.

[0046] In a specific embodiment of the present invention, the preparation of a double-layer colored pulse fabric electrode is carried out according to the production process flow of "construction of a hydrophobic barrier of conductive yarn → integrated weaving → differentiated dyeing and color development → finishing". Specifically, the process includes the following steps:

[0047] Construction of hydrophobic barrier for conductive yarn: The conductive yarn with metal coating is immersed in the treatment solution, and then the yarn is impregnated and dried on a sizing machine at a speed of 30 m / min to 100 m / min, with the tension adjusted to 250 N to 350 N and the drying temperature to 60 ℃ to 100 ℃. The treatment solution contains copper powder, antioxidant, type 2099 PVA, and crosslinking agent.

[0048] Curing: The impregnated conductive yarn is cured at 120℃~180℃ for 1 min~8 min to form an antioxidant layer and a hydrophobic protective layer on the surface of the conductive yarn;

[0049] Integrated weaving: Conductive yarns with antioxidant and hydrophobic protective layers are used as warp and weft yarns, and combined with hydrophilic cellulose fiber yarns, they are integrally formed into a double-layer fabric base on an air-jet loom using a 1-space-1 plain weave structure. Figure 5 As shown, Figure 5 The image shows the weaving pattern for preparing the double-layer colored pulsed fabric electrode of this invention. Yellow represents knot nodes, and the actual pattern represents weft weft nodes. The double-layer pulsed fabric electrode is woven using an air-jet loom at a weaving speed of 400-600 r / min. The warp tension is controlled at 15 cN / thread to 25 cN / thread, and the weft tension is controlled at 15 cN / thread to 25 cN / thread.

[0050] Differential dyeing and color development: The double-layer fabric base is cold-batch dyed using an aqueous dyeing solution. A dual-reactive-group or dual-functional-group reactive dye is selected according to the target color. The dyeing solution is prepared with a dye concentration of 1 g / L to 50 g / L, and 10 g / L to 50 g / L of fixing alkali is added. The pulse fabric electrode is then immersed in the dyeing solution with a liquid retention rate of 63% to 68%. The dyeing is carried out at 25℃ to 40℃ for 8 to 12 hours, followed by washing, low-temperature soaping, washing again, and drying. The hydrophilicity of the cellulose fiber yarn is utilized to color it, while a hydrophobic protective layer on the surface of the conductive yarn blocks dye adhesion, thus preserving the natural color of the conductive yarn and coloring the cellulose fiber yarn.

[0051] Post-treatment: The dyed fabric is impregnated with a biodegradable non-silicone softener with a liquid retention rate of 70%~75%, and then dried to obtain a double-layer colored pulse fabric electrode.

[0052] The present invention will be further described below with reference to the embodiments:

[0053] Example 1

[0054] 100D silver-plated nylon yarn was selected as the base yarn. A treatment solution with a mass fraction of 0.2% copper powder, 3% antioxidant, 5% 2099 type PVA, and 12% crosslinking agent was selected, with the balance being water. The base yarn was immersed in the treatment solution and then subjected to single-yarn impregnation and drying on a sizing machine at a speed of 60 m / min, a tension of 300 N, and a drying temperature of 80℃. The yarn was then cured at 160℃ for 3 min.

[0055] The treated 100D silver-plated nylon yarn was used as both warp and weft yarns, along with 60-count Tencel yarn. The base fabric was a double-layered fabric woven on an air-jet loom, with both upper and lower layers being plain weave with a 1-interval, 1-strand pattern. Specifically, two types of yarns were configured in both the warp and weft directions: Group A was non-conductive 60-count Tencel, and Group B was 100D silver-plated nylon yarn. The warp yarns were arranged in a (2A2B) * n cycle, with 2A yarns passing through one front warp heald and one back warp heald. Combined with the double-layered fabric structure, the fabric presented an effect where the front warp or front weft yarns showed a (1A 1B) * n cycle when viewed individually. The weft yarns were also arranged in a 2A 2B sequential weft insertion pattern. With the "jointed double-layered structure," the conductive yarns were embedded into the fabric at preset intervals, forming regular conductive grids or stripes, thus achieving a precise alternating arrangement of conductive and non-conductive yarns. The weaving speed is 500 r / min, the warp tension is controlled at 20 cN / thread, and the weft tension is controlled at 20 cN / thread.

[0056] The woven double-layer pulse fabric electrode is dyed. Specifically, the woven double-layer pulse fabric base is cold-batch dyed with an aqueous dyeing solution. A dual-reactive-base dye is selected according to the target color, and a dyeing solution is prepared with a dye concentration of 30 g / L. 34 g / L of fixing alkali is added, and the pulse fabric electrode is immersed in the dyeing solution with a liquid retention rate of 65%±3%. It is piled and dyed at 30℃ for 12 h, followed by water washing, low-temperature soaping, water washing, and drying.

[0057] The dyed double-layer pulse fabric electrode is post-finished by impregnating the dyed fabric with a biodegradable non-silicone softener with a liquid retention rate of 70%±3% and then drying it to obtain a double-layer colored pulse fabric electrode.
