Description

Specification

Foot sheet and insole for footwear using the same

Technical field

[0001] One aspect of the present invention relates to a foot sheet, and a foot tape, an insole for footwear, a toe sack, and footwear using the same.

[0002] Another aspect of the present invention relates to the prevention and disinfection of off-flavors in a living environment.

[0003] Still another aspect of the present invention relates to the structure of a tool for preventing cracks and tears generated near the soles.

Background art

[0004] With regard to one aspect of the present invention, the bacteria inside the shoe are proliferated immediately, and therefore, athlete's foot fungi (scabies fungi) are generated between the soles of the feet and the toes, and a bad odor is generated. . In order to prevent athlete's foot and bad odors, for example, Japanese Patent Publication No. 1 61041 discloses a shoe insole having a copper ion generating layer as an insole having antibacterial and deodorizing effects. In this copper ion generating layer, a metal sprayed layer made of zinc or aluminum is formed on the surface of the insole of the shoe, and a copper sprayed layer is further formed on the upper surface thereof. In addition, for example, utility model registration No. 3006612 discloses an insole for shoes in which a copper thin film foil that generates copper ions and has antibacterial and deodorizing properties is attached to the entire insole substrate. . This shoe insole can have a zinc thin film foil or an aluminum thin film foil bonded to the lower surface of the copper thin film foil.

[0005] With regard to another aspect of the present invention, socks, shoes, bags, etc. generate a strange odor during daily life. The skin other than this place is not noticeable by the person, but others often feel a strange odor. In order to prevent this, activated carbon is locally placed, special chemicals are sprayed locally, wiping, bathing, and frequently changing items are carried out. The masks are devised to prevent off-flavors, sterilization propagation and infection by putting activated carbon in the gauze layer or arranging antibacterial and antibacterial agents. The effect is temporary, and it is a daily occurrence that the mask feels unpleasant after wearing for a long time. In this regard, measures such as disinfection after washing and replacement with new ones are taken. As with masks, Ommut has not been as good as sterilization and odor generation. In particular The current status of Omutsu used by elderly caregivers is that it is good and has no methods other than frequent replacement. Pet huts, fresh flower water, kitchen sinks, kitchen wastewater outlets, cutting boards, refrigerators, humidifiers, etc. also produce odors during use. In these cases, deodorant is sprayed, activated carbon is placed, washed frequently, and copper and silver are placed locally to prevent the generation of off-flavors, but satisfactory results have not been obtained. It is in. The bath water also produces a strange odor when it is used repeatedly by boiling and circulating hot water. The current situation is that there is no better way to deal with this problem, but there is no choice but to redraw it. Rivers, lakes and seawater in the vicinity of cities become eutrophic due to domestic wastewater, and the generation of off-flavors due to microorganisms is increasing. This is also impossible for activated carbon, and there are currently only methods such as purifying inflowing domestic and industrial wastewater or diluting with clean water.

In addition, disinfectants are sprayed in public facilities, livestock facilities, aquaculture facilities, hydroponic cultivation facilities, etc. where an unspecified number of people come and go in order to maintain a good sanitary environment. There is a need for a better method that can only provide an effect.

[0006] Regarding yet another aspect of the present invention, cracks and scratches are skin tearing phenomena that occur on the soles of the feet. As a method for preventing this phenomenon, various external preparations are mainly used. In addition, it has been proposed to apply alkaline electrolyzed water. However, many people have little pain, and it is difficult to see because they are hidden behind shoes and socks. For example, the following documents are known as structures for preventing cracks and cracks. Japanese Patent Application No. 6-261946 (Japanese Patent Laid-Open No. 8-99860), Japanese Patent Application No. 7-34170 6 (Japanese Patent Laid-Open No. 9-176030), Japanese Patent Application No. 10-13284 (Japanese Patent Laid-Open No. 11-199470) ), Japanese Patent Application No. 7-175968 (Japanese Unexamined Patent Publication No. 9-25236), Utility Model Registration No. 3108 859

BEST MODE FOR CARRYING OUT THE INVENTION

[0016] First, a foot seat according to one aspect of the present invention will be described.

The present invention relates to a foot sheet worn on a foot. The foot sheet of the present invention includes at least two kinds of conductive materials.

[0017] In the foot sheet of the present invention, when an electrolyte is present between the conductive materials, it is preferable that a potential difference of 0.:! To 2V in absolute value occurs between the two types of conductive materials. The presence of an electrolyte between conductive materials forms a chemical battery, which is considered to cause a potential difference between the conductive materials. The potential difference generated between the conductive materials is preferably 0.3 to 1.8 V, and more preferably 0.6 to 1.5 V. The foot sheet of the present invention can kill bacteria that cause athlete's foot and the like due to the potential difference generated between the conductive materials contained in the foot sheet, and can also kill bacteria. Can prevent bad smell caused by bacteria. If the potential difference is less than 0.4, a sufficient bactericidal effect cannot be obtained, but if the potential difference is 0.:! To 2V, a sufficient bactericidal effect can be obtained.

[0018] Note that the conductive material preferably shows a potential difference within the above range stably in a state where an electrolyte is present between the conductive materials, but even in a short time or periodically, What is necessary is just to show the electric potential difference in the said range. Note that it is preferable that the potential difference itself always occurs between the conductive materials in the state where the electrolyte exists between the conductive materials.

[0019] The potential difference generated in the foot sheet containing the electrolyte can be measured, for example, by the following method. First, an electrolyte containing an electrolyte is impregnated between the conductive materials of the foot sheet. As the electrolytic solution, a buffer solution such as a phosphate buffer solution, an acetate buffer solution, a Tris buffer solution, a bicarbonate solution, or a salt solution can be used. Thereafter, the terminal of the potential difference measuring device is connected to the conductive material, and the potential difference between the conductive materials is measured. A commercially available voltmeter may be used as the potentiometer.

[0020] Further, as a simple method, an electrolyte is contained in the foot sheet, and one surface of the foot sheet; In some cases, a potential difference can be measured by connecting a terminal to the other surface.

[0021] The foot sheet exhibits a bactericidal effect when worn on the foot, for example, as a foot tape, an insole for footwear, a sack for toes, or footwear. It is preferable to wear the foot sheets mainly on the soles of the feet and between the toes, where the bacteria are likely to grow, and the bacteria that sweat and are quickly humid. When you wear it, you can wear it directly on your skin or wear it via socks or supporters. When wearing directly on the skin, wear socks, supporters, etc. on the foot sheet.

[0022] When the foot sheet is worn, sweat from the skin covered with the foot sheet or the surrounding skin is taken into the foot sheet. The incorporated sweat can act as an electrolyte because it contains electrolytes such as sodium chloride, urea, and lactic acid.

[0023] When the foot sheet of the present invention is worn on the foot, the absolute value between the two conductive materials is 0.

03- 1. It is preferable that a potential difference of 5V occurs. The potential difference generated between the conductive materials is preferably 0.1 to 1.0 V, and more preferably 0.2 to 0.6 V. If the potential difference is less than SO.03V, a sufficient bactericidal effect cannot be obtained, but if the potential difference is 0.03 to: 1.5V, a sufficient bactericidal effect is obtained.

[0024] It is preferable that the conductive material stably exhibits a potential difference within the above range when the foot sheet is worn on the foot. What is necessary is just to show the electric potential difference in the above-mentioned range. In addition, it is preferable that the potential difference itself is always generated between the conductive materials when the foot sheet is worn on the foot.

[0025] The potential difference generated in the foot sheet worn on the foot can be measured, for example, by the following method. First, the foot sheet prepared for the insole of the shoe is brought into contact with the sole, and then a supporter is put on the foot sheet to fix the foot sheet to the sole. After that, put your shoes on the supporter and spend several minutes for several hours. After a few minutes to several hours, take off your shoes and connect the terminal of the potentiometer to the conductive material while the foot sheet is fixed to the sole by the supporter to measure the potential difference between the conductive materials. . A commercially available voltmeter may be used as the potentiometer. Instead of using a supporter, foot tape can be fixed to the foot using commercially available adhesive tape.

[0026] Further, as a simple method, a foot sheet is worn on the foot, and one side of the foot sheet is connected to the other surface. In some cases, a potential difference can be measured by connecting a terminal to the other surface.

[0027] The foot sheet of the present invention can inhibit the development of ringworm. The fact that the sheet for foot of the present invention is a sheet capable of inhibiting the development of ringworm bacteria forms a halo (development zone) in the low test ClIS L 1902) using ringworm bacteria. It can be confirmed by whether or not.

[0028] In the present invention, it is considered that the bacteria are killed by the action of the potential difference generated between the conductive materials on bacteria such as ringworm that live on the feet such as the soles and toes. Therefore, it is preferable that the foot sheet has a form in which a potential difference generated between the conductive materials can act on the foot, that is, a form in which the conductive material and the foot are not insulated.

[0029] From the viewpoint of potential difference generation, the two kinds of conductive materials are preferably in contact with each other or close to each other. When close to each other, there may be a space between the two conductive materials, and other materials may exist between the two conductive materials as long as they do not interfere with the presence of the electrolyte. . Examples of other materials include an adhesive or pressure-sensitive adhesive, clay, water-soluble polymer, cloth, and paper.

[0030] Preferably, the foot sheet includes a conductive material A and a conductive material B having a lower electrode potential than the conductive material A as the two types of conductive materials.

Examples thereof include alloys containing the above metals, materials having a coating containing these metals, and carbon materials. As the conductive material A and the conductive material B, a combination in which the above-described potential difference is generated between the conductive material A and the conductive material B is selected and used from these materials. In addition to the conductive material A and the conductive material B, the foot sheet may further include any other conductive material.

[0031] The conductive material A is preferably a carbon material from the viewpoint of easily generating a high potential difference. Examples of the carbon material include graphite, carbon black, carbon fiber, activated carbon, and charcoal. Preferred is graphite or carbon black, and more preferred is carbon black. Graphite or carbon black is preferred as an industrial product because a large amount of high-quality, stable products can be supplied at low cost, and electrical conductivity is high. Used. Furthermore, if the graphite or carbon black is in powder form, it can be mixed with an adhesive or a pressure-sensitive adhesive to form a coating film, and if the adhesive or pressure-sensitive adhesive is hygroscopic, it is in a powder form. There is an advantage that an electrolyte is easily contained in the gap between graphite and carbon black. Since graphite is usually agglomerated, it often undergoes a pulverization step to make it into a powder form, but carbon black can obtain fine particles of 0.1 mm or less without going through a pulverization step. Carbon black is more preferably used. Furthermore, the surface of the carbon black is rich in activity and has excellent affinity with the electrolyte.

[0032] When the conductive material A is a carbon material, the conductive material B is selected from magnesium, aluminum, zinc, iron, titanium, nickel, tin, lead, copper, silver, and gold. Examples thereof include a metal, an alloy containing two or more metals selected from these metals, or a material having a coating containing these metals. Examples of the alloy include brass, stainless steel, and aluminum magnesium alloy. In addition, examples of the material having a film containing these metals include materials plated with these metals, specifically, tin and tin. The conductive material B is preferably a metal selected from magnesium, aluminum, zinc, iron, titanium, nickel, tin, lead, copper, silver, and gold, or two or more selected from these metals. An alloy containing a metal, more preferably aluminum or an aluminum alloy. Aluminum or an aluminum alloy is easily available and is a suitable metal for generating a potential difference.

[0033] The forms of the conductive material A and the conductive material B in the foot sheet are not particularly limited as long as the above-described potential difference can be generated between the conductive material A and the conductive material B. For example, a form in which a layer (a) containing conductive material A and a layer (b) containing conductive material B are laminated, a linear material containing conductive material A, and conductive material B Examples include a form in which a layer containing the conductive material A and the conductive material B is formed by knitting, weaving, or alternately arranging the linear material containing the material. In the present invention, the layer (a) containing the conductive material A and the layer (b) containing the conductive material B are preferably laminated.

In the present invention, the layer (a) containing the conductive material A is a carbon material-containing layer ( _a ′), and the layer (b) containing the conductive material B is an aluminum-containing layer (b ′). It is preferable that

[0035] The carbon material-containing layer (a ') is made of graphite, carbon black, carbon fiber, activated carbon, charcoal, etc. It is a layer containing a carbon material. In the present invention, a layer containing graphite or carbon black is preferable, and a layer containing carbon black is more preferable.

[0036] Examples of the carbon material-containing layer (a ') include a layer made of a sheet-like carbon material such as a graphite sheet, a carbon fiber sheet, and a charcoal sheet, and a fiber shape such as a long-fiber carbon fiber (roving). There are layers containing carbon materials such as graphite powder, carbon black, carbon fiber powder (fine fiber carbon fiber), activated carbon powder, charcoal powder and other layers containing powdered carbon material. The layer containing a powdery carbon material can be formed using, for example, a composition containing a powdery carbon material and an adhesive or a pressure-sensitive adhesive. In the present invention, a layer containing a powdery carbon material is preferable from the viewpoint that the specific surface area is large, which is advantageous for expression of a potential difference, and that a stable potential difference can be generated. The properties of the composition may be any of emulsion, paste, and bowl.

[0037] For example, when graphite powder is used, its particle size is preferably 60 mesh JIS Z 8801-1; standard sieve defined in 2000) or less. For example, when carbon black is used, the average secondary particle size (volume basis) is preferably 0.001 to 0.1 mm (laser diffraction particle size distribution measurement).

[0038] Examples of the adhesive include natural adhesives such as glue, starch, cellulose, raw rubber, and rosin, thermosetting resin adhesives such as phenol resin and epoxy resin, α-age refin resin, and acetic acid. Thermoplastic resins such as bur resin, aqueous isocyanate resin, synthetic rubber, polyurethane, attalinole resin, butyl acetate, vinyl chloride-vinyl acetate copolymer, ethylene monovinyl acetate copolymer (EVA), etc. Adhesives or these modified adhesives can be used. Examples of the pressure-sensitive adhesive include acrylic resin-based pressure-sensitive adhesives. Examples of the solvent contained in the adhesive or the pressure-sensitive adhesive include water, methanol, ethanol, acetone, methyl ethyl ketone (MEK), ester-based homogeneous 1J, or a mixed solvent thereof, preferably water. Or a mixed solvent of water and methanol, ethanol, acetone, methyl ethyl ketone (MEK) or an ester solvent.

[0039] In the present invention, a water-soluble or water-dispersible adhesive or pressure-sensitive adhesive is preferred, and an adhesive or pressure-sensitive adhesive containing a water-soluble polymer or hydrophilic polymer is preferably used. . Examples of water-soluble polymers or hydrophilic polymers include polyvinyl alcohol and polyacryl Polybulu compounds such as acid, polyacrylolamide, polybulumethyl ether, polybulur pyrrolidone, acetic acid bull, chlorinated bluic acid monoacetate bull copolymer, ethylene monoacetic acid bull copolymer (EVA) Examples include polyethers such as polyethylene oxide and polypropylene oxide, polyesters such as water-soluble alkyds, polysaccharides such as carboxymethylenocellulose, methylcellulose, ethylcellulose, and starch, polypeptides such as glue, gelatin, and casein, and rosin. It is done. A polybule compound is preferable. As a water-soluble or water-dispersible adhesive or pressure-sensitive adhesive, commercially available adhesives or pressure-sensitive adhesives can be used. For example, starch paste for shoji (made by Asahi Pen Co., Ltd.), Lua Mild (made by Yayoi Chemical Co., Ltd.) ), Bond CN series (manufactured by Konishi Co., Ltd.), Cemedine EM series (manufactured by Cemedine Co., Ltd.), Sdyne 7000 series (manufactured by Sekisui Chemical Co., Ltd.), Ivon (manufactured by Aika Kogyo Co., Ltd.) it can.

[0040] The content of the powdery carbon material in the adhesive or pressure-sensitive adhesive composition is preferably 30 to 70% by weight, preferably 40 to 60% by weight, based on the total weight of the composition. More preferably, it is 50 to 55% by weight. The content of the adhesive or pressure-sensitive adhesive in the composition is preferably 30 to 70% by weight, more preferably 40 to 60% by weight, and even more preferably 45 to 50% by weight. . When the content of the powdered carbon material is less than 30% by weight (when the content of the adhesive or the pressure-sensitive adhesive exceeds 70% by weight), the conductivity of the carbon material-containing layer (a ′) decreases. When the content of the powdered carbon material exceeds 70% by weight (when the content of the adhesive or pressure-sensitive adhesive is less than 30% by weight), the carbon material-containing layer (a ') There is a tendency for the strength to be insufficient or for the carbon powder to fall off.

[0041] The carbon material-containing layer ( _a ') may also contain clay. The clay contains, for example, kaolinite and montmorillonite, which preferably contains at least one mineral selected from force orinite, montmorillonite, talc, quartz, smectites and vermiculites. It is particularly preferred. As the clay, kaolin clay and bentonite are preferably used. When carbon material powder and clay are mixed, aggregation of carbon material powder can be prevented and dispersibility can be improved. As a result, the specific surface area of the carbon material powder increases and a large potential difference occurs. In addition, due to the ion exchange function of clay, electric double Since formation of a layer can be prevented, a stable potential difference can be generated over a long period of time. Furthermore, since clay has a moisturizing effect, it is also possible to add a function as a moisturizing agent to the foot sheet.

[0042] When the carbon material-containing layer (a ') contains clay, the carbon material-containing layer (a') is added to the composition containing the carbon material and an adhesive or a pressure-sensitive adhesive, and further added with clay. It can be formed using. The content of clay in the composition is preferably 0.:! To 40% by weight relative to the total weight of the composition: more preferably 3 to 5% by weight! % Is more preferable. If the clay content is less than 0.1%, the effect of using the clay tends to be difficult to obtain. If the clay content exceeds 40% by weight, the content of the carbon material powder is relatively reduced. Therefore, the generated potential difference tends to be small.

[0043] When the composition is used, for example, the carbon material-containing layer (a ') can be formed by applying the composition to a substrate such as cloth or paper and then drying the composition. The carbon material-containing layer (a ′) thus obtained contains a base material. The substrate is preferably a cloth from the viewpoint of moisture permeability. Cloth materials include cotton, wool, polyester, vinylon, urethane, nylon, acetate, acrylic, rayon and polyolefin. Examples of the fabric include woven fabric, non-woven fabric, and knitted fabric. Preferably, it is a woven fabric. The woven fabric has a texture due to its nature, and the texture is a space connecting the front surface and the back surface of the fabric, and the electrolyte can freely pass through this space. As the woven fabric, plain weave such as canvas, twill, mesh, fluff (pile) and the like can be used. Canvas (canvas) is a cotton fabric, and is preferably used because it is highly versatile and excellent in moisture retention, and has high strength and low price. In addition, since paper contains cellulose, it is a preferable material for generating a potential difference that has a high ability to retain an electrolyte having a high water absorption rate. As the paper, it is preferable to use high-density paper, resin-treated paper, mixed paper or the like from the viewpoint of strength.

[0044] For application of the composition to the substrate, a method of spreading the composition on the substrate using a spatula, a roll or the like, a method of impregnating the composition with the substrate, a screw-type continuous kneader ( For example, a method of extruding the composition and spreading it on a substrate while rolling with a roller, a method by printing such as gravure printing, offset printing, sinoleta screen printing, etc. can be used. . The coating amount is preferably 5 to 100 g / m ² and 10 to 60 g. It is still more preferred more preferred instrument 30 to 50 g / m ² is / m ^2. For drying the coated composition, for example, a method of leaving the coated composition at room temperature for 5 to 10 hours is preferably used. In addition, a method of heat drying (60 to 200 ° C., 3 to 20 minutes) using a tunnel type infrared dryer or a tunnel type hot air dryer can also be used.

[0045] Alternatively, the carbon material can be obtained by applying the composition to a temporary substrate such as a plate or film made of plastic, metal, or the like, drying the composition, and then peeling the composition layer from the temporary substrate. The containing layer (a ′) can be obtained.

[0046] Furthermore, the composition can be directly applied onto the aluminum-containing layer (b ') and dried to obtain the carbon material-containing layer (a').

[0047] Next, the aluminum-containing layer (b ') is a layer containing aluminum or an aluminum alloy. An example of the aluminum alloy is an aluminum magnesium alloy.

[0048] Examples of the aluminum-containing layer (b,) include a thin plate, foil, net, and a layer containing aluminum or aluminum alloy powder formed of aluminum or an aluminum alloy. The layer containing aluminum or aluminum alloy powder can be formed, for example, by the same method as the above-described layer containing a powdery carbon material. As the aluminum-containing layer (b ′), an aluminum foil is preferably used because it is flexible and can easily form foot sheets having various shapes.

Can be 10 to: 1,000 xm, preferably 30 to 500 111, and more preferably 50 to 200 μm. If the thickness is less than 10 μm, the layer (b) containing the conductive material 易 tends to break, and it tends to be difficult to use practically, and if it exceeds 1,000 zm, it is uneconomical. If the seat is used as an insole for footwear, it is easy to break.

It is preferable that From the viewpoint of potential difference generation, the layer (a) containing the conductive material A and the layer (b) containing the conductive material B are preferably in contact with each other or close to each other. Les. Therefore, the distance between the two layers is 0 to: 1,000 zm. The force S is preferable, and 0 to 800 xm is more preferable. Furthermore, it is preferably 0 to 500 mm 111, more preferably 0 to 300 zm, and even more preferably 0 to 150 xm. If one or both of the layer ( _a ) containing the conductive material Α and the layer (b) containing the conductive material B are distorted rather than flat, the distance between the two layers Are not necessarily uniform.

[0054] In the case where the layer (a) containing the conductive material A and the layer (b) containing the conductive material B are close to each other, a space may be used between the layers. Other materials may be present as long as they do not hinder their existence. When the layer (a) containing the conductive material A is in contact with the layer (b) containing the conductive material B, or when these two layers are close and have a space between them, it functions as an electrolyte. Sweat etc. can easily penetrate between the layers.

[0055] Further, the layer (a) containing the conductive material A and the layer (b) containing the conductive material B are close to each other, When other materials are present between the layers, the other materials are preferably hygroscopic and water-absorbing materials. Examples of such materials include water-soluble or water-dispersible adhesives or pressure-sensitive adhesives, water-absorbing polymers such as clay, polybulal alcohol monoacrylic acid copolymer, and the like.

[0056] When the layer (a) containing the conductive material A and the layer (b) containing the conductive material B are bonded using an adhesive or an adhesive, the area of the unbonded portion is: There is no particular limitation as long as it is adjusted depending on the type of adhesive used. In general, from the standpoint that an electrolyte is easily present between layers and preventing peeling of both layers, the area of the unbonded portion is 20 to 85% of the total area of the footsheet. More preferably, it is 50 to 75%, more preferably 60 to 70%. However, a foot sheet using a water-soluble or water-dispersible adhesive or pressure-sensitive adhesive absorbs sweat that acts as an electrolyte, and sometimes the adhesive or pressure-sensitive adhesive itself functions as an electrolyte. In order to emit light, a sufficient potential difference is generated even if the area of the unbonded portion is 0%. Therefore, when a water-soluble or water-dispersible adhesive or pressure-sensitive adhesive is used, the area of the unbonded portion is not sufficient from the viewpoint of preventing the peeling of the two layers and the ease of the manufacturing process. 0 to 50% of the total area of the sheet for use is preferably 0 to 30%, and more preferably 0%.

[0057] The layer (a) containing the conductive material A and the layer (b) containing the conductive material B can be pressed and bonded using a roll laminator or a flat plate type press machine. . In order to prevent delamination between the two layers, at the time of bonding, at least the outer periphery of the layer (a) containing the conductive material A and the outer periphery of the layer (b) containing the conductive material B are bonded. It is preferable to do. In this case, it is preferable to use a water-soluble or water-dispersible adhesive or pressure sensitive adhesive in consideration of permeation of electrolyte such as sweat. Further, a part or all of the outer peripheral portions may be fixed with cloth, paper, cellophane, a vinyl base adhesive tape or the like so as to wrap around the end portion of the foot sheet.

[0058] When the foot sheet of the present invention is worn on the foot, the potential difference generated in the foot sheet acts on the bacteria living in the foot and kills the bacteria. When the foot sheet is worn on the foot, the layer facing the foot may be either the layer (a) containing the conductive material A or the layer (b) containing the conductive material B. Preferably, it exhibits an excellent bactericidal effect From the viewpoint of being able to do so, the layer (a) containing the conductive material A having a high electrode potential is made to face the foot.

[0059] The thickness of the foot sheet can be appropriately set depending on the application, material, etc., and is preferably 0.3 to 7 mm or less, more preferably 0.3 to 5 mm. More preferably, it is 5 to 3 mm. If the thickness is less than 3 mm, the resistance to the flexion movement of the foot is insufficient and the life tends to be shortened, and if it exceeds 7 mm, the wearing feeling tends to be poor.

[0060] Depending on the mode of use, the foot sheet of the present invention has a first surface facing the sole and a second surface facing the ground (c), the first surface of the support. A layer (b) containing the conductive material B laminated thereon, and a layer (a) containing the conductive material A laminated on the layer (b) containing the conductive material B (b). It is preferable to use it. A foot sheet provided with such a support is preferably used as an insole for shoes. As the material for the support, for example, polyethylene terephthalate (PET), polycarbonate (PC), polypropylene (PP), polyethylene (PE), acrylic resin, vinyl chloride resin, natural or synthetic rubber, and leather can be used. The thickness of the support can be appropriately set depending on the application, and is preferably 0.:! To 2 mm. 0.:! To 1.5 mm is more preferable 0.3. 1 mm is more preferable. When the layer (b) containing the conductive material B is laminated on the first surface of the support, the layer (a) containing the conductive material A, the layer (b) containing the conductive material B, The adhesive or pressure-sensitive adhesive used when adhering can be used.

[0061] The foot sheet of the present invention may further include (d) a protective layer as long as it does not interfere with the bactericidal effect. (D) The protective layer can be preferably formed on the surface of the layer facing the foot. (D) The protective layer is preferably a breathable or moisture-permeable protective layer, for example, cotton, a woven fabric made of synthetic fiber, a mesh or a non-woven fabric made of a thermoplastic resin. The thickness of the protective layer is preferably 0.05 to 3 mm, more preferably 0 to 2.5 mm, and even more preferably 0.3 to 2 mm. If it is less than 0.05 μm, the protective layer effect may not be obtained. If it exceeds 3 mm, the foot sheet becomes thick, and when used as an insole for footwear, the comfort may be poor.

[0062] In order to adhere and fix the protective layer and the conductive material, a commercially available spray paste may be used as long as it does not interfere with the sterilization effect. In that case, the amount of spray paste applied is The amount is preferably 5 to 15 xm, and more preferably 7 to 10 zm. Examples of spray pastes include acrylic rubber-based spray paste (Saladun's spray spray, Paint Shop's IP light proof), acrylic emulsion-based spray paste (Sekisui Chemical Esdine, Konishi Bond CN series), Examples include polyurethane spray pastes (Nippon Polyurethane Coronate L, Zest Corp. U series) and rubber spray pastes (Chinese paint Rabax 1000 series).

[0063] The foot sheet can be used as a foot tape, an insole for footwear, a toe sack, or the like in the form of a tape, a sole type, a finger sack, or the like. In addition, the foot sheet can be used as a sole for footwear by making it into a sole shape. Examples of footwear include shoes, sandals, boots, slippers, socks, tabi, and supporters.

[0064] The foot sheet of the present invention can be preferably used as an insole for footwear. An insole for footwear is obtained by cutting a foot sheet into a sole mold. When foot sheets are used for insoles for footwear, a material that can withstand flexion movement of the sole as a material of the layer (a) containing the conductive material A and the layer (b) containing the conductive material B Is preferably selected. From such a viewpoint, a carbon material is a preferable material. In particular, it is possible not to wear both layers on the insole of the footwear that touches the joint at the base of the toes where the flexing movement is intense. That is, the insole for footwear can be used by cutting the toe portion, the base portion of the toe, and the heel portion, and laying only the toe portion and the heel portion in the footwear. In addition, as shown in FIG. 1 below, only the layer (a) containing the conductive material A and the layer (b) containing the conductive material B were cut, and the layer containing the cut conductive material A was cut. The layer (b) containing (a) and the conductive material B may be covered with a support and a protective layer.

An example of an insole for footwear is shown in FIG. The insole for footwear preferably includes a layer (a) 21 containing a conductive material A, a layer (b) 22 containing a conductive material B, and a support 23. Further, a protective layer 24 may be provided. In the figure, 25 is a space created by cutting an insole for footwear into a toe portion and a heel portion.

[0066] The insole for footwear of the present invention can be used in the same manner as a conventionally known insole.

The insole for footwear of the present invention can be used, for example, by laying on the inside of a shoe, the inside of a sock, or the sole of a supporter. [0067] The foot tape preferably has a size of 10 to 30111111 20 to 50111111, and can be used by sticking to the toes or sticking to the foot. The toe sack can be formed by using a foot sheet and can be used by covering the toe. Further, the foot sheet of the present invention can be cut into a foot mold and used as a part of the sole of footwear.

[0068] Conventionally, for the purpose of sterilization, a metal having a sterilizing action, for example, copper ions has been often used. However, when copper ions are used, coloring of the feet and footwear by the copper ions has been a problem. In addition, activated carbon or the like was often used for the purpose of deodorization, but there was a problem that the effect was not sustained. The foot sheet of the present invention is a sheet that can solve these problems by selecting an appropriate material. The foot sheet of the present invention is a sterilizing sheet that has excellent sterilizing power and can be used for a long period of time without using a material having a sterilizing action. Furthermore, the foot sheet of the present invention is a deodorizing sheet having an excellent deodorizing power due to an excellent sterilizing power. By using the foot sheet of the present invention, bacterial growth can be suppressed, so that athlete's foot can be prevented and treated, and further, malodor can be prevented and deodorized. The foot sheet of the present invention is preferably used as a disinfectant, an athlete's foot treatment tool, and a deodorant.

If coloring is not a problem, of course, copper can also be used as the conductive material in the present invention. In addition, it may be preferable to use a material having a bactericidal action as the conductive material because a synergistic effect with a bactericidal action due to a potential difference can be expected.

[0069] In addition, the foot sheet of the present invention generally has low air permeability and excellent moisture retention compared to thin socks and the like. Usually, in the environment of high humidity, various bacteria can easily propagate and easily generate bad odor. The foot sheet of the present invention has an excellent deodorizing and sterilizing effect, and thus can be moisturized and deodorized. For this reason, the foot sheet of the present invention can prevent and treat cracks, cracks and the like due to its excellent moisturizing power in a state in which malodors and germs are suppressed.

[0070] Furthermore, the foot sheet of the present invention generates a slight amount of heat due to the electrochemical reaction and diesel heat generated in the foot sheet, and thus has an excellent heat retaining effect. Its excellent heat retention can prevent and treat poor blood circulation and frost burn.

[0071] The foot sheet according to one aspect of the present invention uses a material that itself has a bactericidal action. It is a sheet that can be used for a long period of time even if it has excellent sterilizing power and deodorizing effect.

[0072] Next, the structure for sterilization prevention and sterilization, which is another aspect of the present invention, will be described.

When metals with different electrode potentials and their alloys are brought close to each other, electrons are transferred, and metals with low potentials are oxidized. The carbon material is not a metal, but has conductivity and an electrode potential is generated in the same manner as the metal, and the paired metal is oxidized. This phenomenon is promoted especially when a little moisture is present. Here, negatively charged electrons are generated near the surface of the metal to be oxidized and move toward the metal or carbon material. The oxidized metal gradually falls off, and negatively charged electrons are accumulated near the surface of both metals, and are discharged and disappear. This creates an environment in which microorganisms are difficult to propagate, and the generation of off-flavors caused by microorganisms is eliminated.

[0073] As a result of various experimental studies, arbitrarily selected two kinds of magnesium, aluminum, titanium, zinc, chromium, iron, nickel, tin, lead, copper, silver, noradum, platinum, gold, and alloys of these metals, It was found that when they were brought close to each other, microorganisms stopped breeding in the vicinity and some of the microorganisms disappeared. Amorphous carbon such as carbon fiber, graphite, and charcoal was also effective. Although it is not conductive, clay also has an electrode potential, and it was particularly effective when mixed with graphite material. Among the above materials, zinc, titanium, aluminum, iron, tin, copper, and carbon materials are preferable from the viewpoint of economy and hygiene. Platinum, gold, and silver are also suitable materials unless they are expensive. For the combination of the two materials, one material is selected from each of group A of zinc, titanium, aluminum, iron and copper and group B of iron, copper, silver, platinum, gold and carbon materials. The metals selected from Group B are combined so that the electrode potential is higher than the metals selected from Group A. Iron and copper have a coloring effect during use and should be avoided if you dislike it. Selecting three or more types of metals from these two groups is effective, but since electrons are exchanged mainly between the two substances with the largest potential difference, it is possible to combine at least two types of materials. This is a condition of the present invention. These two types of materials are easy to use in the form of foil, mesh, thin plate with small holes, fiber or cloth. When used in paint or paste form, powder. The two selected materials are in close proximity to form a composite. So For this method, a method of layering is simple. In addition, they may be twisted linearly to form a string, and finally finished into a net. The carbon material is made into a paste with an adhesive containing a moisturizing agent such as glue or gel, and is used by painting it on aluminum foil, etc. It may be covered with foil. At this time, if a cloth is interposed as a base material in the coating film, it is effective for reinforcing and helping moisture penetration and moisture retention. Carbon fiber can be used in the form of a sheet. When used in shoes, it is better to combine aluminum or zinc foil or net, perforated plate and stainless steel foil, fibrous or netted in layers. In order to provide breathability and flexibility, the mask and the ommu are preferably made by laminating a net-like, fiber-like, or cloth-like material. The cocoons should have a sticky carbon paste applied to aluminum foil. Compounding can be made into a cylindrical shape or bag shape according to the shape of the object. For example, the composite structure to be placed around the toes is shaped like a socks. Rings and chains that fit on fingers, arms, necks, etc. shall also be composite structures according to the local shape. As the fiber, a natural fiber or synthetic fiber with a metal arranged on the surface or a metal processed into a fiber shape can be used. When building composite structures, they are simply fixed mechanically so that they do not move easily. When using pressure-sensitive adhesives or adhesives, use as little glue or starch-based or vinyl-based synthetic resin pressure-sensitive adhesives or adhesives as possible. It is effective to include a water-retaining substance such as a gel. A small amount of water-insoluble adhesives and adhesives can be used. Foil-like objects are torn or disappear, so the thickness should be 0.1 to 0.3 mm. You can reinforce it with a plastic film. Materials other than foil are extremely wear-free and can be used semipermanently. For complex shapes such as door knobs in hospital rooms, etc., it is only necessary to combine tentacle components with two types of materials.

The interface between the laminated materials should be in contact with each other or with a state force close to contact, with a sheet-like material such as paper or cloth or a water-absorbing synthetic resin sheet in between. At this time, if a small amount of sodium chloride is included in the sheet material, the exchange of electrons is promoted, and the sodium chloride is partially changed to sodium hypochlorite to produce a disinfection and sterilization effect. The salt content may be 10% by weight or less based on the base material. 1 to 5% by weight is preferable. During use, these composites contain sweat from the human body, moisture that comes out with breathing during breathing, and skin coating agents. Water in the air, moisture in the air, and moisture at the time of excretion invade and oxidize group A metals. In the case of sink drains, rivers, lakes, and seawater, water near each odor source plays a role. Humidifiers play the role of moisture in the air coming out of the outlet.

[0075] The skin surface in the vicinity of the composite structure of the present invention has less sculpture of wrinkles, and effectively acts on this part that tends to become a microbial nest. The heels and cracks on the soles of the feet are almost invisible and the heels appear.

The end of the laminated composite may be protected by attaching a plastic pressing cover. In particular, in the case of a cloth-like or net-like composite, it is necessary to prevent fraying at the end. For articles such as socks, fibers or linear threads may be knitted to form a composite. In the case of a mask or omgu, a composite with a shape slightly smaller than the gauze, cloth or fiber forming the whole is inserted between the gauze, cloth or fiber.

[0076] In rivers, lakes and marshes with poor water flow, and in closed bays, microorganisms propagate and cause off-flavors due to water eutrophication. Attempts to adsorb nutrients with activated charcoal etc. The current situation is that it will soon saturate and not work well. The effect of the composite structure of the present invention is maintained because it prevents odors caused by microorganisms not by adsorption but by the properties of water in the vicinity of the composite. In the case of rivers, lakes, seas, etc., because the target area is wide, the composite structure must be designed based on the individual geographical situation. A simple method is to wrap charcoal in a group A metal such as aluminum or iron and let it flow. In the experiment, it was found that there was no adherence of algae and other nasty smells. With charcoal alone, algae grew over the entire surface of the charcoal and had little effect.

[0077] For the shoe sole, a method of attaching a composite in the shape of the sole to the shoe sole is preferable. A 0.3mm diameter aluminum wire and a stainless wire are twisted together, processed into a net, and attached to the inner bottom of the shoe. The pet shed is also larger in shape, but a similar composite structure is acceptable. For socks, put this in your socks. The shape is curved or a bag-like part is provided so that the composite structure comes into contact with the toes and heels.

The mask should be interposed between the gauze as a slightly smaller shape than the gauze, using a net-like composite of aluminum wire with a diameter of 0.1 mm and stainless steel wire. The heel is fixed to the heel by using the adhesiveness of the paste with aluminum foil coated with adhesive carbon paste on one side of a circle with a diameter of around 3cm. When this composite structure is used on the neck, face, etc. in addition to wrinkles, the wrinkles on the skin surface, which are rich in microorganisms, become smooth, and exhibits the effect of removing microorganisms. At this time, the carbon paste may be applied to the body and then the aluminum foil may be coated thereon.

The drainage outlet of a sink can be effective by simply placing a composite of charcoal in a copper or iron fence. The chopping board is good when stainless steel nets and charcoal are placed on the surface. There is no need to place charcoal on the entire surface, only one. For fresh flowers, there are two types of swordsman needles, brass and aluminum, and these needles are arranged alternately. The pedestal can be an insulator.

The humidifier is arranged in two layers of aluminum and stainless steel mesh at the outlet. This method can also be applied to air conditioners and ventilation fans. At this time, the negative ion effect is also expected due to the negative charge of the electrons.

The present invention is to prevent odor and sterilize by using a special environment in which two kinds of substances close to each other can exchange electrons. We believe that the effect is lasting and stimulates consumer cleanliness and is widely accepted by the market.

[0079] The composite structure according to another aspect of the present invention is effective in preventing odor generation and sterilization. In addition, according to the experience of the present inventor, athlete's foot athlete's foot also disappeared. The blood pressure increased from 80 to 90, increased to 105, and white blood cells increased from 3500 to 7500, improving anemia. It is presumed to be an effect related to body current. These health benefits will be confirmed by increasing the number of samples in the future. Negative ion effects of negatively charged electrons can also be expected. It has also been confirmed that it is difficult to see wrinkles on the skin, and a cosmetic effect can be expected.

[0080] Further, a structure for preventing cracks and scratches, which is still another aspect of the present invention, will be described.

When metals with different electrode potentials and their alloys are brought close to each other, electrons are transferred, and metals with low potentials are oxidized. At this time, heat is generated slightly. The carbon material is not a metal, but it has conductivity and the electrode potential is generated in the same way as the metal, and the paired metal is oxidized in close proximity. This phenomenon is promoted especially when even a small amount of moisture is present. Here, negatively charged electrons are generated near the surface of the metal to be oxidized, and the corresponding metal or carbon is generated. Move towards the raw material. The oxidized metal gradually falls off, and negatively charged electrons become abundant in the vicinity of both metal surfaces. When such an environment occurs near the skin of the sole, body fluid oozes out near the skin in combination with an increase in the temperature of the sole, resulting in a moist state. As a result of the experiment, two sheets of magnesium, anoleum, titanium, zinc, chrome, iron, nickelo, tin, lead, copper, silver, palladium, platinum, gold, and alloys of these metals were selected and combined into a composite sheet. When the structure was attached to the sole, it was found that the sole became damp and the cracks and cracks around it disappeared. Carbon materials such as carbon fiber, graphite, and charcoal were also effective. Among the above materials, a composite structure in which metals such as zinc, titanium, aluminum, iron, tin, alloys thereof, and carbon materials are preferable from the viewpoint of economy and hygiene. Platinum, gold, and silver are also suitable materials if they are not expensive. For the combination of the two materials, select one material each from Group A of zinc, titanium, aluminum, and iron and Group B of iron, silver, platinum, gold, and carbon materials. The materials selected from Group B are combined so that the electrode potential is higher than the material selected from Group A. Although copper is an effective material, it was removed because of its coloring effect. Effective force even when 3 or more types of metals are selected Since the transfer of electrons is performed substantially between the two substances with the largest potential difference, at least two types of materials selected from group A and B are placed close together It is necessary to make it. When this composite structure is attached to the sole, the area around it becomes damp due to the body fluid secreted from the sole, and the cracks and red spots disappear naturally. Conventional skin external preparations may be used in combination, but most of the cracks and reddening disappeared only by the moisturizing effect of the body fluid secreted by itself. However, to the extent that the subcutaneous tissue is exposed, it is necessary to apply the composite structure of the present invention after treatment by a specialist.

These two types of materials can be used as thin plates, foils, nets, thin plates with small holes, woven fabrics, non-woven fabrics, and powdered pastes. The combined thickness is preferably about lmm or less. The sole is uneven, and the vicinity of the thumb joint is bent so that it can follow the shape and movement of the sole. The bent part is dealt with by the flexibility of the composite, and the part is made with a simple hinge structure. For example, the structure near the thumb joint is cut back and forth

Reconnect the cut piece with a soft cloth tape. Carbon materials are flexible It is easy to follow the movement of the thumb joint that can be easily processed into paint or paste. The two selected materials are in close proximity to form a composite. The proximity distance is preferably about 1 mm or less. As the method, a layered method is simple. Wear this layered composite in the shape of a sole. A layered tape may be attached to the sole. In this case, use a thin material such as aluminum foil or stainless steel foil. In addition, a material having a net or a small hole may be combined in a layer. Compounding is performed by bringing them close to each other, but they may be close to each other or partially close. It is convenient that the bottom surface of the composite is perforated so that moisture can enter the adjacent portion as much as possible. In that sense, a thin plate with a small hole is suitable. The carbon material is made into a paste with an adhesive containing a moisturizing agent such as glue or gel, and is used by painting it on aluminum foil or applying it to an object such as skin. An aluminum foil may be covered. At this time, if a cloth is interposed as a base material in the coating film, it is effective to assist reinforcement and moisture retention. Carbon fiber is used in the same way as foil.

This composite structure is used by being fixed to a shoe in advance, used as an insole, or put in a sock for use on a sole. When fixing in shoes, it is convenient to embed the composite structure when molding the sole. The composite structure should be shaped like a ship bottom to match the shape of the soles. It is also possible to form a bag like a socks around the toes. A material in which a metal is arranged on the surface of natural fiber or synthetic fiber can also be used. In this case, a composite structure that is knitted into the sole of the sock is recommended. It is also possible to use a non-woven fabric in which two types of metal fibers are mixed to form a sheet. The two types of materials that are close together are fixed so that they cannot move easily. As a method for this, it is easy to use an adhesive tape that does not move. When using adhesives or adhesives for fixing, use as little as possible of synthetic resin adhesives such as glue, starch or vinyl. It is effective to include a water-retaining substance such as a gel. A small amount of water-insoluble adhesives and adhesives can also be used.

The foil must be 0.1 to 0.3 mm thick because it will tear or disappear. When using it as a bandage, it is possible to use a thinner one. At this time, it should be reinforced with a plastic film. Materials other than foil consume very little and are permanent Can be used for a long time. The interface of the layered materials can be in contact with each other or close to contact, or in a state where a sheet-like material such as paper or cloth or a water-absorbing synthetic resin sheet is interposed therebetween. The end of the composite structure is protected by attaching a plastic presser cover. In particular, it is necessary to prevent the fraying phenomenon at the edge of a cloth-like or net-like composite.

[0083] The present invention uses a special environment created by two kinds of materials close to each other to give and receive electrons to secrete their body fluids, and this moisture prevents cracking and tearing. We believe that the effect is sustainable, and it will be widely accepted by the market by stimulating people's cleanliness.

[0084] The composite structure according to still another aspect of the present invention exhibits remarkable effects in preventing cracks and scratches that are problems. Immediate effects, effectiveness, and sustainability that are not found in conventional external preparations for skin and alkaline electrolyzed water can be obtained. Moisture generated during use does not cause odor or sliminess.

Example

[0085] Hereinafter, the present invention will be described in more detail with reference to examples. However, the present invention is not limited to the following examples.

[0086] [Example 1]

Graphite powder (manufactured by Hitachi Powdered Metallurgy, Hitachi GP-60S) lOOg and acetic acid bur-based adhesive (manufactured by Chao Chemical Co., Ltd., Vinegar Vistil, Rua Mild) are taken on a stainless steel plate, kneaded with a pestle, and uniform in viscosity. A cocoon-shaped composition (hereinafter referred to as a composition) was obtained. The composition, key Yanbasu (Kinoshita materials manufactured, # 250D white) on one side of, and applied have use lm ² per 50 g, a spatula and roll, allowed to stand for 5 hours at room temperature, drying and curing, graphite powder A containing layer (thickness about 0.5 mm) was formed. Aluminum foil on the other side of the canvas (Nihon Foil Co., Ltd., 1N30, thickness 0.07mm) double-sided adhesive tape (Nitto Denko, acrylic adhesive tape, No. 500, thickness 0.015mm, width) 15 mm) to produce a two-layer composite. For shellfish occupancy, the two-layer composite is cut into a foot shape in a later step, and then the graphite powder-containing layer that becomes the cut end and the aluminum foil foil are bonded to each other with a double-sided adhesive tape. Went to. After that, on the surface of the graphite powder-containing layer that is not in contact with the aluminum foil, 10 g of spray paste based on acrylic rubber (Sala Dung, Gnolace Play) is applied per lm ^{2 and} made of polyester fiber. A 60-mesh net (Semitec, PET60, thickness of about 0.2 mm) was covered to make a composite.

[0087] Next, from the composite, a foot mold of size 24cmE (one each on the left and right) was cut off with a scissors to obtain an insole for footwear. The thickness of the insole for footwear was about lmm. The application area of the double-sided adhesive tape was 40% of the area of the foot sheet. The obtained insole for footwear was cut along a line connecting the thumb root joint and the little finger root joint. Then double-sided tape on the insole for the shoe so that the toe side of the insole is on the toe side of the shoe, the heel side of the insole is on the heel side of the shoe, and the aluminum foil surface is on the sole Fixed with. The shoe size used was 26 cmEE.

[0088] A patient whose foot and toes were affected by athlete's foot was wearing socks and wearing shoes with an insole on them, and a decrease in foot athlete's foot was observed after 2 days. In about one month, the athlete's foot between the soles and fingers, and the fingernails except for the thumbs disappeared, and the skin of the soles became smooth and shiny. Also, the smell of shoes and socks never occurred immediately after wearing the shoes.

[0089] The potential difference generated in the insole 10 minutes after the insole for footwear was laid inside the shoe and the patient put on the shoe was 200 to 400 mV.

[0090] In the examples, the potential difference was measured by the following method using an insole for footwear before being fixed to the shoe sole unless otherwise specified. First, the insole for footwear is brought into contact with the sole so that the layer (a) containing the conductive material A (the carbon-containing layer surface in Example 1) faces the sole, and then the footwear is being used. In order to fix the insole to the sole, a supporter was put on the insole for footwear. After that, I put on shoes on the supporter and spent a certain time (10 minutes in Example 1). After a certain period of time, the shoes are removed and the insole for footwear is fixed to the soles by the supporter. The conductive material is a tester (AP_ 5526, manufactured by A & D Co., Ltd., production number 1 050578640). Terminals were connected and the potential difference between the conductive materials was measured. The supporter and protective layer (60 mesh net made of polyester fiber in Example 1) had holes for terminal insertion. 5 measurement points (Measure the potential difference by touching the terminal to the front and back of the 2-layer laminate so that the terminals face each other across the 2-layer laminate for any 5 locations of the 2-layer laminate. The measurement time at each location is 5 seconds. The potential difference is the ( (Minimum value to maximum value) It was expressed as mV.

[0091] FIG. 2 shows an example of an insole for footwear fixed to a sole by a supporter. In the figure, 11 is a layer containing conductive material A (a) (in Example 1, a graphite powder-containing layer), 12 is a layer containing conductive material B (b) (in Example 1, aluminum foil), 13 Is a support (not used in Example 1), 14 is a protective layer (60 mesh net made of polyester fiber in Example 1), 15 is a space, and 16 is a supporter.

[0092] After 1 month, the color of the surface of the aluminum foil not in contact with the graphite powder-containing layer was slightly changed to white. This is considered to be because aluminum was oxidized.

[0093] [Comparative Example 1]

An insole for footwear containing no aluminum foil was prepared in the same manner as in Example 1 except that the aluminum foil and the double-sided adhesive tape for bonding the aluminum foil to the graphite powder-containing layer were not used. A patient whose foot and toes were affected by athlete's foot was wearing shoes with an insole for footwear, and no effect on athlete's foot disappeared after one month.

[0118] 2. Test method

(1) Test bacteria

Trichophyton rubrum TIMM 2659 (Trichophyton)

[0119] (2) Preparation of bacterial solution

The spore of the test bacterium obtained using the agar medium was suspended in a physiological saline supplemented with 0.05% polysorbate 80, and adjusted to 10 ⁶ to 10 ⁷ / mL to prepare a bacterial solution.

[0120] (3) Preparation of test plate medium

a) Method A

First, a specimen with the test surface (sheet surface) up was placed in the center of a plastic petri dish (diameter 90 mm). Sabouraud Agar (Eiken Chemical Co., Ltd.) 10 mL of the bacterial solution was added to 150 mL, and the mixture was added to the plastic petri dish so that it was poured around the sample (so that the agar did not come into contact with the sample surface).

[0121] (4) Judgment method

The test plate medium was cultured at 25 ° C. for 8 days, and after culturing, the presence or absence of a halo (growth inhibition zone) around the sample was determined by visual observation. The test was performed 3 times (n = 3) using 3 petri dishes for each specimen. In addition, the test was performed in the same manner on a test plate medium without a specimen.

[0122] The results are as follows.

In the non-specimen control, growth of ringworm was confirmed throughout the petri dish. When Sample A and Sample B were used, halo formation was not observed in all three Petri dishes in either Method A or Method B.

When Specimen C was used, small halos were observed in petri dishes in 2 of 3 with Method A and 1 out of 3 with Method B.

When specimen D was used, formation of a minimal halo was observed in all three petri dishes in both method A and method B (Fig. 4 (1) Method A and (2) Method.

When specimen E was used, formation of a clear halo circle around the specimen was observed in all three dishes in both method A and method B (Figure 4 (3) Method A, (4) Method .

[0123] Specimens A and B did not show any antibacterial effect. Considering the difference between Specimen C with and without halo formation, halo formation in the test using Specimen C is not due to the antibacterial effect of Specimen C alone. It is considered that the trace metals contained therein acted as the two kinds of conductive materials in the present invention and exhibited an antibacterial effect. Samples D and E showed antibacterial effects. In particular, the antibacterial effect superior to Specimen E was perceived.
