Description

 TECHNICAL FIELD [0001] The present invention relates to a micro-current generating cloth,

 The present invention relates to a micro-current generating fabric and a manufacturing method thereof, and more particularly, to a micro-current generating fabric which is fabricated to produce a micro-current capable of generating a micro-current even without a separate power supply device, .

 Electronic fabrics are commonly used in functional devices that can be embedded in clothing. The device combined with the fabric is applied to a portable electric device which is flexible for human wear, is not inconvenient to move, is light, and does not provide a hazardous environment such as generation of electromagnetic radiation which is dangerous to health.

 Wearable devices using electronic fabrics have been extensively studied, ranging from textile global positioning systems (GPS) to textile products that respond to biological signals and the surrounding environment.

 In order to improve the performance of electronic fabric, various researches have been carried out, but most of studies on the following two methods are under way.

 First, the bottom-up method is a method of weaving using conductive fibers or yarns to make electronic fabrics. Nanocarbon materials such as carbon nanotubes and graphenes having conductivity are often used as electronic fabric materials. Flexible electrodes may also be formed by weaving textiles in a polymer network.

Second, the up-to-bottom method is to use a coating film that is conductive to the basic fabric. Composites in the form of carbon nanotubes, graphenes, and nanotubes and graphene, which are materials used in coating films, have been studied as coating film materials because they have high conductivity and flexibility and are easy to process in solution. Currently, the up-to-bottom fabrics industry including nylon, cotton, and polyester is preferred over bottom-up. Therefore, usually electronic fabric is produced by up to bottom method.

Single-layer graphene thin films are advantageous in that they are transparent, flexible, durable and have high electrical conductivity. Therefore, the electronic fabric is manufactured by coating the graphene on the fabric, and the sheet resistance of the electronic fabric at this time is as high as about 1 k? / Square.

 Electron woven fabrics made with nitric acid treated graphene have a sheet resistance of about 700 Ω / square, but have a high sheet resistance for application in electronic systems. High sheet resistance is a significant limitation for wearable devices.

 On the other hand, when carbon nanotube ink is used, the sheet resistance of the electronic fabric is less than 1? / Square. However, when coated with carbon nanotube ink, the fabric becomes opaque and loses its original color and gloss. In particular, the use of the wearable optoelectronic device (for example, a solar cell or the like) or a display is limited.

 In addition, in the case of optoelectronic devices, fiber-based solar cells that are attached to clothes have been actively studied, but they have many problems in mass production of large-area solar fabrics and solar cells.

These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It should be understood that the various embodiments of the present invention are different, but need not be mutually exclusive.

 Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

 Products using micro currents can vibrate blood vessels using micro-currents (less than 1mA) similar to bioelectrons flowing in the body, effectively to stroke, urinary incontinence, prostate hypertrophy, pain relief, blood circulation or wrinkle improvement. Can be used in portable medical devices that repair damage to nerves, muscles, or tissues.

 However, existing products that can generate micro currents have disadvantages such as high volume and high cost, so that they can be utilized in products that can treat and prevent themselves from the stress and pain diseases of busy modern people. It is necessary to purchase a simple and low-cost product and to commercialize it so that it can be easily carried at home or at work.

 1 is a flow chart illustrating a method of fabricating a micro-current generating fabric according to an embodiment of the present invention.

 Referring to FIG. 1, a method of fabricating a micro-current generating fabric comprises the steps of first printing an electrically conductive paste composition on a fiber layer 100 having electrically insulator properties to form a '+' electrode and a ' An electrode layer 200 is formed so as to cross each other (S110).

 In one embodiment, the fiber layer 100 is not limited to materials such as face dyes, synthetic fabric fibers, carbon fibers, face mask materials, clothing, patches, etc., For example, 0.1 mm to 3 mm).

 In one embodiment, the electrode layer 200 is formed by printing a conductive paste composition on the top of the fiber layer 100 by a printing method, and includes an adhesive composition in the conductive paste composition to be printed on the top of the fiber layer 100, Can be prevented.

 Unlike the ink-jet ink, the pastes used in the screen printing method in the printing method, which is mainly applied to the electrode pattern formation of electronic products, disperse a large amount of conductive component in the polymer binder, print, dry and cure, .

 At this time, the conductive paste is required to have different physical properties depending on the application field. In addition to excellent electrical properties, the conductive paste is required to have uniform printing characteristics, adhesion to substrates, abrasion resistance against external friction, weather resistance (heat resistance or moisture resistance) And chemical resistance to the above.

 In the case of the paste for mounting wiring, the deterioration characteristics of the bonding strength are important, and the reproducibility of the resistance value and the like must be ensured.

 The adhesive force, abrasion resistance, weather resistance, and chemical resistance to the substrate are often controlled by a binder and a solvent. Electrical characteristics, uniform printing characteristics, and reproducibility of resistance values are determined by the type of conductive particles.

 Accordingly, the conductive paste according to the present invention includes particles of an electrically conductive material, which is a conductive metal, a non-metal or an oxide, a carbide, a boride, a nitride, a carbonitride powder thereof, Based carbon powder.

 The conductive paste particles include at least one material selected from the group consisting of gold, aluminum, copper, indium, antimony, magnesium, chromium, tin, nickel, silver, iron and titanium, Carbide, boride, nitride, or carbonitride.

 In this case, the shape of the particles is not particularly limited. For example, plate-like, fiber-like and nano-sized nanoparticle nanotubes can be used, and these conductive particles can be used alone or in combination.

 Unlike the conductive ink used in inkjet printing or the like, the conductive paste may further include a binder to improve adhesion with the substrate. In general, an epoxy resin, a phenol resin (phenol + formaldehyde) polyurethane resin, a poly An organic binder such as an amide resin, an acrylic resin, a urea / melamine resin, and a silicone resin can be used.

 Here, the content of the binder may generally be in the range of 10 to 50 parts by weight, and preferably in the range of 15 to 40 parts by weight, based on the content of the total paste composition, but is not limited thereto.

 Further, the binder serves as a cause for reducing the electrical conductivity of the electric wire layer including the conductive paste as described above.

 The viscosity of the conductive paste composition used in the present invention may be in the range of 10,000 cps to 100,000 cps as measured by HAKKE RHeoscope at 23 ㅀ C, 50 rpm, but is not limited thereto.

 In one embodiment, the adhesive composition is an adhesive composition comprising a topical and a curing agent, the subject of which comprises 30 to 90 parts by weight of an ethylene vinyl acetate (EVA) resin, 1 to 30 parts by weight of polyvinyl alcohol (PVA) 5 to 30 parts by weight of calcium carbonate, 0.1 to 1 part by weight of a surfactant, and 1 to 20 parts by weight of a thixotropic agent. The curing agent includes an isocyanate compound.

 The adhesive composition used in the present invention is a water-soluble two-component adhesive composition comprising a subject and a curing agent, and may be included in the conductive paste composition so as to assist the efficient printing of the conductive paste composition on the fiber layer 100.

 In addition, the adhesive composition used in the present invention is excellent in physical properties such as adhesiveness and heat resistance without polluting the environment, and can be used as an inorganic board such as a wood board or a magnesium board such as plywood, a sheet of various plastics such as PVC Lt; / RTI >

 Here, the subject basically comprises an ethylene vinyl acetate (EVA) resin, polyvinyl alcohol (PVA), water, calcium carbonate, a surfactant and a thixotropic agent, the ethylene vinyl acetate resin being the main component of the subject, The strength of the object to be manufactured can be kept constant.

 Conventionally, an epoxy resin is mainly used. When an epoxy resin is used, volatile organic compounds such as benzene toluene are released, which has harmful effects on the environment and human body.

 However, the adhesive composition of the present invention can solve problems such as environmental problems by excluding an epoxy resin.

 The polyvinyl alcohol (PVA) serves to improve heat resistance, water resistance and adhesiveness, and is preferably contained in an amount of 1 to 30 parts by weight based on 30 to 90 parts by weight of the ethylene vinyl acetate resin.

 When the amount of the polyvinyl alcohol is less than 1 part by weight, it is difficult to improve the heat resistance or the like, and when it exceeds 30 parts by weight, the relative content of ethylene vinyl acetate is decreased and the cohesive strength may be weakened.

 In addition, antimony oxide and zirconium oxide may be used together with polyvinyl alcohol to supplement the functionality of polyvinyl alcohol when used in an ondol floor or the like.

 Here, antimony oxide and zirconium oxide are materials capable of improving heat resistance, and they are preferably contained in an amount of 5 to 10 parts by weight per 30 to 90 parts by weight of the ethylene vinyl acetate resin. When the amount is less than the range, the effect of improving the heat resistance is insignificant , And it is uneconomical to exceed the range.

 Water is used as a solvent for the subject. It does not use a volatile organic solvent and has the effect of solving environmental pollution problem.

 Water is preferably contained in an amount of 10 to 30 parts by weight based on 30 to 90 parts by weight of the ethylene vinyl acetate resin. When the amount of water is less than 10 parts by weight, the ethylene vinyl acetate resin or the like can not be effectively dissolved. , It may become too thin and the strength may be lowered.

 Calcium carbonate is preferably contained in an amount of 5 to 30 parts by weight based on 30 to 90 parts by weight of the ethylene vinyl acetate (EVA) resin, to control the viscosity of the adhesive composition and reduce the shrinkage upon curing.

 When the amount of calcium carbonate is less than 5 parts by weight, sufficient shrinkage does not occur during curing and the hardness may become poor. When the amount of calcium carbonate exceeds 30 parts by weight, the viscosity may become too tight and productivity may be deteriorated.

 In addition, the adhesive composition according to the present invention may be substituted with calcium carbonate and used in various materials such as scouring and clay. For example, dolomite and / or talc may be used.

 At this time, it is preferable to mix dolomite and talc in a weight ratio of 1: 1 in order to improve mechanical properties. It is also preferable that the powder has a particle size of 150 to 200 mesh. When the powder is used to have a particle size of 150 to 200 mesh, it is mixed with other components such as ethylene vinyl acetate resin Can be improved.

 The surfactant is used to reduce the surface tension when mixing the adhesive composition and to improve the application property. The surfactant is preferably contained in an amount of 0.1 to 1 part by weight based on 30 to 90 parts by weight of the ethylene vinyl acetate resin.

 As the surfactant, known nonionic surfactants and anionic surfactants can be used, but in order to effectively reduce the surface tension, it is preferable to use a gemini type sulfonic acid type surfactant containing an alkyl chain of 8 to 14 carbon atoms.

 The thixotropic agent is to prevent the adhesive composition from flowing down by suppressing the separation phenomenon between the top and the curing agent when the electrode layer 200 containing the adhesive composition is attached to the fibrous layer 100. Examples of the thixotropic agent include silica, Various known materials can be used, but clay is preferably used.

 Clay is an aggregate of fine hydrated silicate minerals. It refers to a material that is mixed with water in an appropriate amount to produce plasticity when kneaded, rigidity when dried, and sintered when baked at high temperature.

 Specifically, at least one powder selected from the group consisting of kaolinite, fumed silica and bentonite may be used, but in order to obtain the best effect, it is preferable to use a mixture of fumed silica and bentonite in a weight ratio of 1: 1.

 The thixotropic agent is preferably contained in an amount of 1 to 20 parts by weight based on 30 to 90 parts by weight of the ethylene vinyl acetate resin. If the thixotropic imparting agent is less than 1 part by weight, the flowability can not be controlled sufficiently, and if the thixotropic imparting agent is more than 20 parts by weight, the flowability is excessively vanished and the productivity may be lowered.

 In addition, the subject may further comprise sodium silicate to improve adhesion. Unlike conventional adhesives, sodium silicate does not cause pollution and is environmentally friendly and has excellent adhesion.

 The sodium silicate is preferably contained in an amount of 3 to 7 parts by weight based on 30 to 90 parts by weight of the ethylene vinyl acetate resin based on the solid content. When the amount of sodium silicate is less than 3 parts by weight, the degree of improvement of the adhesion performance is insignificant. When the amount is more than 7 parts by weight, miscibility with other components may be deteriorated.

 In addition, the base may further contain molybdenum disulfide to improve wear resistance. Molybdenum disulphide (MoS2) is found in thin veins in minerals and is mined and used as a lubricant.

 Molybdenum disulfide (MoS2) has inherent properties of a hexagonal crystal structure in which shear is likely to occur, such as graphite, but the lubricating action is superior to that of graphite. The molybdenum disulfide is preferably contained in an amount of 1 to 5 parts by weight based on 30 to 90 parts by weight of the ethylene vinyl acetate resin based on the solid content.

 When the amount of the molybdenum disulfide is less than 1 part by weight, the abrasion resistance can not be improved effectively, and when it exceeds 5 parts by weight, the adhesion strength may be deteriorated. At this time, copper powder may be mixed with molybdenum disulfide.

 Further, the subject may further include a flame retardant agent to improve the flame retardancy. The flame retardant is preferably contained in an amount of 1 to 5 parts by weight based on 100 parts by weight of the ethylene vinyl acetate resin.

 When the amount of the flame retardant is less than 1 part by weight, the degree of improvement of the flame retardancy is insignificant. When the amount is more than 5 parts by weight, the flame retardant agent is not only economical but also has poor compatibility with other components.

 The flame retardant may be a white powder. Potassium alum (potassium aluminum sulfate, AlK (SO4) 2 12H2O) can be used for alum, and it can be obtained from natural alum.

 Concretely, it can be produced by dissolving alunculus in water and filtering it, then breaking it, and cooling it if irregularly shaped crystals are formed.

 In addition, the subject may further include aluminum hydroxide to improve antibacterial activity. It is preferable to use boehmite (AlOH (OH)) as the aluminum hydroxide. Boehmite can be any of γ-boehmite, α-boehmite and pseudo-boehmite. Of these, γ-boehmite excellent in crystallinity and excellent in thermal stability and chemical stability, structurally neutral, and excellent in antibacterial property is preferably used.

 The γ-boehmite can be prepared by supercritical synthesis of only water (pure water) and aluminum (Al). The aluminum hydroxide is preferably contained in an amount of 5 to 10 parts by weight based on 30 to 90 parts by weight of ethylene vinyl acetate. If the content of aluminum hydroxide is less than 5 parts by weight, it is difficult to exhibit the antimicrobial effect to be achieved. If the content is more than 10 parts by weight, the compatibility with other components may be impaired.

 As the curing agent, those containing an isocyanate compound can be used. The isocyanate compound has excellent solubility in water, and the curing agent can be uniformly mixed on the subject to maintain proper viscosity and hardness, thereby shortening the curing time and prolonging the pot life when mixing the curing agent and the curing agent, .

 The isocyanate compound is preferably a compound containing two or more isocyanate groups in one molecule, and is preferably a compound containing at least two isocyanate groups in a molecule, such as toluene-diisocyanate (TDI), hydrogenated TDI, trimethyl propane- Triisocyanate (TTI), diphenylmethane-4,4-diisocyanoate (MDI), hydrogenated MDI, or hexamethylene-diisocyanate (HDI) Is preferably used. The curing agent is preferably contained in an amount of 1 to 20 parts by weight based on 100 parts by weight of the subject.

 The above-mentioned adhesive composition is prepared by mixing a subject and a curing agent into a water-soluble two-component type, and if necessary, a part of the constituent component may be excluded or all of the constituent components may be used, and within the range not hindering the object of the present invention A dispersing agent, a defoaming agent, an antiseptic agent, a thickener, and the like, and may further include a coloring component to realize various colors.

 Hereinafter, the structure and effects of the present invention will be described in more detail with reference to specific examples and comparative examples. However, this embodiment is intended to explain the present invention more specifically, and the scope of the present invention is not limited to these embodiments.

 80 parts by weight of ethylene vinyl acetate, 20 parts by weight of polyvinyl alcohol, 25 parts by weight of water, 10 parts by weight of calcium carbonate, 1 part by weight of a surfactant and 5 parts by weight of a thixotropic agent were mixed to prepare a subject. Toluene-diisocyanate and 25 parts by weight of a curing agent containing toluene-diisocyanate (TDI) were mixed and cured to prepare an adhesive sheet or an adhesive.

 At this time, a gemini surfactant having 8 carbon atoms was used as a surfactant. The overall process of synthesis of the surfactant started with the reaction of diamine with 1-bromoalkane. 0.1 mole of N, N, N ', N'-tetramethyl-1,3-diaminopropane (N, N', N'- -bromooctane) was added to 300 g of acetonitrile and stirred for 30 minutes. The solution was refluxed at 353 K for 12 hours, and then the acetonitrile solvent was removed using a rotary evaporator. 500 g of diethylether was added to the resulting product to recrystallize the product. After filtering, it was washed with 500 g of diethyl ether and unreacted impurities were removed. The product thus obtained was treated in a 323 K vacuum oven for 12 hours to remove residual solvent to prepare a gemini surfactant.

[Example 2]

[Table 2]

 As can be seen from the above Table 2, in the Examples, yellowing portions were hardly observed unlike the Comparative Examples. As a result, it was found that the heat resistance of the example was very excellent as compared with the comparative example.

[Experimental Example 3: Evaluation of antimicrobial activity]

 The adhesive compositions of Example 3 and Comparative Examples were subjected to an antibacterial activity test (JIS Z 2801). Aspergillus niger ATCC 9642 (fungus) was used as the test strain and the antibacterial activity (antibacterial activity value) was evaluated and shown in Table 3 below.

The direct printing method may include a printing method such as screen printing, flexographic printing, rotary printing, gravure printing, offset printing, or dispenser. Conventionally known means may be used for each printing method. In the present invention, screen printing, gravure printing, or offset printing is preferable among the printing methods.

 On the other hand, in general, a circuit wiring implemented by printing a conductive paste on the fiber layer 100 has a high resistance and is not suitable for use as a circuit wiring due to poor conductivity. In addition, when a general solder paste is used, There is a problem. To solve this problem, a metal plating layer can be formed on the conductive paste wiring.

 In the present invention, the metal plating layer formed on the conductive paste wiring layer may be formed by electrolytic plating or electroless plating.

 When the metal layer 300 is formed in step S210, the fiber layer 100 on which the electrode layer 200 and the metal layer 300 are formed is inserted into the inner space of the wrapping paper 400 that can seal the inner space (S310 ).

 When the fibrous layer 100 is inserted into the inner space of the wrapping paper 400 in the above step S310, the fibrous layer 100 is inserted into the inner space of the wrapping paper 400 so as to ionize the metal layer 300, An electrolyte 500 (e.g., brine) is injected into the inner space of the electrode assembly (S140).

 When the electrolyte 500 is injected in the step S140, the electrolyte 500 is injected into the inner space of the wrapping paper 400, and the inner space of the wrapping paper 400 is sealed and vacuumed (S150).

 Here, the layer formed by the electrolyte (500) is formed by solidifying the gel (colloidal solution (sol)) to a certain concentration or more and forming a durable net structure. The layer is composed of a hydrogel such as agar, tofu, silica gel, The electrolyte 500 is injected into the inner space of the wrapping paper 400 at the same time as being vacuum packed and serves to ionize the metal layer 300 by oxidizing the metal layer 300 do.

 The micro-current generating fabrics manufactured by the method of fabricating micro-current generating fabrics having the above-described steps are characterized in that the brine battery principle (i.e., aluminum or the like is ionized as the metal layer 300 contacts the brine, The principle of generating electrons by being oxidized by being exposed to oxygen while being opened) can generate a current.

 At this time, it is preferable that the current generated by opening the packaging paper 400 and coming into contact with oxygen is 1 mA or less, and the duration is 10 to 20 minutes.

 The current amount and the duration of the current are determined by the concentration of the composition ratio of the material of the electrode layer 200 and the composition of the high-injection material. The interval between the electrodes formed by the electrode layer 200, Or the concentration of particles such as aluminum may be variously formed according to the desired value.

 3, the wrapping paper 400 is formed by inserting the fibrous layer 100, the electrode layer 200, the metal layer 300, and the electrolyte 500 into the inner space, and then, in order to prevent the inflow of oxygen from the outside, And a fiber layer 100 having an electrode layer 200 and a metal layer 300 formed thereon is inserted into an inner space and sealed and vacuum-packed.

 In one embodiment, the wrapping paper 400 may be formed of a vinyl wrapping paper so as not to be wet or torn by an electrolyte 500 formed of a liquid, but the material is not limited to vinyl, If it is possible to use the packaging, it can be used without being limited to the term.

 When oxygen is introduced into the inner space of the wrapping paper 400 due to thawing of the wrapping paper 400 and the like and the metal layer 300 is located in the inner space of the wrapping paper 400, the metal layer 300, the electrolyte 500 ) And the chemical action by oxygen (that is, by immersing two metals of different reactivity in an electrolyte and connecting the two metals by a lead, the current is generated due to the principle of the current flowing in the chemical cell).

 The electrolyte 500 is injected into the inner space of the wrapping paper 400 in a state where the fibrous layer 100 is inserted into the inner space of the wrapping paper 400 before the wrapping paper 400 is sealed so that the metal layer 300 can be ionized.

 In one embodiment, the electrolyte 500 may be formed of brine, which is generally used in a chemical cell, but may be any material capable of ionizing the metal layer 300, and is not necessarily limited to brine.

 The micro-current generating fabric 10 having the above-described configuration may further include at least one ionization controller 600 (see FIG. 4).

 The ionization control unit 600 is formed on the metal layer 300 and is formed of the same material as the metal layer 300 and is ionized by the electrolyte 500 to generate a current.

 In one embodiment, at least one ionization regulator 600 may be formed at a predetermined interval (for example, 1 mm to 10 mm, etc.) on the metal layer 300 corresponding to the amount of current to be produced additionally.

 In one embodiment, the ionization regulator 600 may include a frame portion 610 and a separator portion 620.

 The frame part 610 is formed of the same material as the metal layer 300 and is provided on the metal layer 300 (for example, by using the above-described adhesive composition or the like), and the separating part 620 is inserted A coupling groove 611 is formed in the upper portion in the longitudinal direction.

 The upper surface of the frame portion 610 is formed flat so that the contact area with the electrolyte 500 is minimized and the separating portion 620 is fastened to the fastening groove 620. [ 611, the area corresponding to the coupling groove 611 is increased, and the contact area with the electrolyte 500 is increased, so that the amount of current produced can also be increased.

 That is, when the separating unit 620 is fastened to the fastening groove 611, only the first area of FIG. 4 will be in contact with the electrolyte 500, but when the separating unit 620 is separated from the fastening groove 611 , An additional area corresponding to the second area is brought into contact with the electrolyte 500, which is further ionized as much as the additional area, so that more current will be generated.

 Therefore, when the user intends to increase the current production, the separator 620 may be separated from the frame portion 610 to further produce a desired amount of current.

  In one embodiment, the fastening groove 611 may be formed in a '+' shape or a '◇' shape in cross section to increase the area in contact with the electrolyte 500. However, the cross-section of the coupling groove 611 is not limited to the above-described shape, but may be formed in various shapes to increase the contact surface with the electrolyte 500.

 The separator 620 is formed of the same material as the metal layer 300 and is formed in a shape corresponding to the shape of the coupling groove 611 and is coupled to the coupling groove 611 or separated from the coupling groove 611.

 The micro-current generating cloth 10 having the above-described structure generates electric current through the oxidizing action by the salt water battery principle, so that a separate electronic device for generating electricity can be omitted, Fabrics can be made.

 In addition, a mask or gauze using a micro current can be produced through a fabric capable of generating electricity, so that it can be utilized for stroke, urinary incontinence, enlargement of the prostate gland, pain relief, blood circulation or wrinkle improvement, (Less than 1 mA) similar to bioelectrons flowing in the blood vessels, which can be used in portable medical devices for restoring damage to nerves, muscles, or tissues causing pain.
