Description

Technical Field

[0001] The present invention relates to a technology using plus and minus charged particles of nanodiamond, and particularly relates to a clothing which contains nanodiamond in the clothing, and by wearing it, it can exert the effect of promoting blood flow by improving bioelectric current and maintain and improve health.

Background Art

[0002] In recent years, wearables for the purpose of maintaining health and recovery have attracted attention. The present invention relates to a clothing which is affected by plus and minus charged particles of nanodiamond on nerve transmission between cells and blood flow, and can exert effects such as promoting blood flow by improving bioelectric current and has an effect on maintaining and enhancing health. In the present invention, the clothing is not limited to clothes, but is defined as all items worn on the body such as hats, accessories, watches, shoes, belts, etc.

[0003] In the human body, a weak bioelectric current of several μA to several tens of μA flows. The bioelectric current is greatly related to the movement of the heart, breathing, and metabolism. When the bioelectric current flows normally, the blood flow is stabilized, the cells are stimulated, and metabolism is carried out.

[0004] Each cell has positive ions and negative ions. In a normal state, negative ions are inside the cell and positive ions are outside the cell, and the balance of ions inside and outside the body is maintained. When the plus-minus balance is disrupted, the flow of bioelectric current is disturbed, the blood flow is not stabilized, and the metabolism deteriorates.

[0005] When the metabolism deteriorates, the energy metabolism deteriorates, resulting in a shortage of energy (ATP adenosine triphosphate). The shortage of energy leads to the deterioration of the original body functions, and various physical discomforts such as stiff shoulders, stiff necks, low back pain, knee pain, and other muscle pains occur due to unnecessary substances, waste products, blood and body fluid stains accumulated in the body. (Patent Document 1)

[0006] Effective clothing for these symptoms includes compression underwear and sports compression wear, which are said to promote blood flow and reduce muscle fatigue by applying a certain amount of pressure. There are also products that use special materials that emit far-infrared rays to raise body temperature and promote blood flow.

[0007] However, excessive compression from compression garments can actually hinder blood flow. Especially when worn for extended periods, it can cause poor circulation and potentially have adverse health effects.

[0008] Because compression garments fit tightly against the skin, friction and pressure can cause skin irritation, itching, and rashes. Those with sensitive skin should be especially careful.

[0009] Furthermore, if compression garments or similar garments are too tight, they can restrict freedom of movement, narrowing the range of motion of joints and muscles during exercise. This not only affects performance but also increases the risk of injury.

[0010] In addition, compression garments can be difficult to put on and take off, which can be a significant burden, especially for the elderly and those with limited physical strength. Wearing them for extended periods can cause discomfort and pain due to the compression, so caution is advised when wearing them during sleep or other activities that may cause discomfort.

[0011] Furthermore, if compression underwear or sportswear is not the correct size, it may not only be ineffective but could also have adverse effects on health. Both excessive and insufficient compression can be problematic.

[0012] Excessive compression over a long period of time may increase the risk of blood clots (venous thromboembolism), and caution is especially necessary for those with a history of this condition.

[0013] Furthermore, special materials that emit far-infrared rays specifically contain minerals. However, natural minerals often contain trace amounts of heavy metals and impurities, which can be irritating to people with sensitive skin. Similarly, prolonged contact can affect the skin. In both cases, symptoms such as redness, itching, eczema, rashes, and dryness may appear.

[0014] In other words, compression underwear and sports compression wear that utilize the technology described in Reference 1 (Patent No. 6347441), which takes advantage of the properties of nanodiamonds, contain the aforementioned risk factors.

[0015] Reference 1 discloses a technical information regarding a patch-type therapeutic device characterized in that a release sheet having holes with a diameter of 1.0 to 5.0 mm and a depth of 50 to 200 μm is attached to the center of the adhesive surface of an adhesive sheet, fine particles of amber are injected into the holes and fixed to the adhesive surface of the adhesive sheet, and further nanodiamonds with a basic particle size of 3 to 10 nm having an activation energy level of 0.1 to 1.0 eV that generate charged particles at human body temperature and emit far-infrared rays are loaded into the holes, and the nanodiamonds are attached to the gaps and surface of the amber.

[0016] However, these adhesive therapy devices utilizing nanodiamonds inherently contain health risks and dangers due to the pressure they exert, and therefore cannot be said to offer a fundamental solution as a health-promoting therapy device for the human body.

[0017] Reference Document 2 (Patent No. 5761597) describes an allergic dermatitis treatment agent comprising dispersing and mixing nanodiamonds having an activation energy level of 0.1-1.0 eV and a particle size of 5-300 nm in a solution or oil at a concentration of 0.0005-3.0 wt%. Claim 2 discloses a technical information regarding an allergic dermatitis treatment agent comprising dispersing and mixing nanodiamonds having an activation energy level of 0.1-1.0 eV and a particle size of 5-300 nm in a solution at a concentration of 0.0005-3.0 wt% and attaching this mixture to a textile fabric by spraying, printing, or melt spinning.

[0018] However, the technology disclosed in Reference 2, like Reference 1, contains the aforementioned health hazards and risks in a patch therapy device utilizing nanodiamonds, and cannot be said to offer a fundamental solution as a health-promoting therapy device for the human body. In addition, the technology disclosed in Reference 2 limits its effectiveness to allergic dermatitis treatment agents only, and does not even mention it as a broad-ranging health-promoting therapy device like the present invention.

[0019] [Patent Document 1] Patent No. 6347441 [Patent Document 2] Patent No. 5761597 [Patent Document 3] Patent application No. 2017-221330 [Overview of the project] [Problems that the invention aims to solve]

[0020] This invention relates to clothing and other garments that incorporate positively and negatively charged nanodiamond particles into fibers, thereby stabilizing bioelectric currents without compression and promoting blood flow in the wearer. The positive and negative charges of the nanodiamonds stabilize the wearer's bioelectric currents, promote blood flow, facilitate metabolism, and reduce muscle fatigue. Furthermore, since nanodiamonds are artificial minerals made of carbon and contain almost no heavy metals or impurities, they do not affect the skin.

[0021] An overview of the method for producing an aqueous dispersion of nanodiamonds will be described. The detonation nanodiamonds, which are the nanodiamonds of the present invention, can be obtained by dissolving the product obtained when a mixed explosive of trinitrotoluene (TNT) and hexogen (RDX) is exploded in an inert medium such as carbon dioxide gas or water with hot nitric acid. The obtained detonation nanodiamond crude product is a powdery substance with strong cohesiveness and a size of 3 to 50 micrometers. By subjecting this powdery substance to wet grinding or the like to perform wet pulverization (disintegration), an aqueous dispersion of nanodiamonds with nanosized particles can be obtained.

[0022] The above aqueous dispersion of nanodiamonds contains impurity components derived from the manufacturing process. The aqueous dispersion of nanodiamonds can be obtained by subjecting it to electrorefining to remove compounds containing metals and metal elements, which are impurities derived from the production of nanodiamonds (Japanese Patent Application No. 2017-221330). As the dispersion medium used for the aqueous dispersion of nanodiamonds, a liquid capable of dispersing detonation nanodiamond particles is preferable. The dispersion medium is preferably water or an aqueous solvent.

[0023] The definition of the nanodiamond solution according to the present invention is a solution in which nanodiamonds are blended in a weight ratio of 0.0005 wt% to 3.0 wt% with respect to the solvent. The solvent is not limited to water solubility or oiliness, but in the description of this application, a nanodiamond solution with pure solvent as the solvent will be described and explained.

[0024] The following description is disclosed in Cited Document 2 (Japanese Patent Application No. 2017-221330).

[0025] Human skin tissue is roughly divided into a three-layer structure. The outermost layer (facing the outside world) is the "epidermis", the layer beneath it is the "dermis", and the bottommost layer is the "subcutaneous tissue". Among them, the "epidermis" is composed of four layers in order from the outermost layer (facing the outside world): the "stratum corneum", the "stratum granulosum", the "stratum spinosum", and the "stratum basale". Here, the stratum corneum, which is the outermost layer of cells in the human body, plays an important role as the boundary between the inside and outside of the human body. One is to prevent the invasion of chemical substances, ultraviolet rays, bacteria, etc. from the outside, and the other is to prevent the escape of body fluid components such as moisture from the body to the outside. This is called the barrier function of the stratum corneum. It is considered that the barrier function in the stratum corneum is mainly played by the intercellular lipids in the stratum corneum cells. Therefore, even if chemical substances such as cosmetic active ingredients try to penetrate from the skin, it is difficult to penetrate deep into the skin tissue due to the barrier function in the stratum corneum. Thus, simply applying a cosmetic containing active ingredients to the skin results in low absorption efficiency from the epidermis, and it is difficult to penetrate even into the dermis.

[0026] The present invention aims to solve the above problems and develop and provide an effective method for skin application and patch application that is not affected by the penetration avoidance function of the barrier function in the skin stratum corneum and can penetrate deep into the skin tissue. The objective and also the problem is to develop an effective method that has high absorption efficiency from the epidermis and can penetrate even into the dermis by simply applying or patching a component containing active ingredients to the skin.

[0027] In addition, the problem of the present invention is to develop and provide clothing and other apparels that can affect intercellular neurotransmission and blood flow by the plus and minus charged particles of nanodiamond, exhibit effects such as promoting blood flow by improving bioelectric current, and have an effect on maintaining and enhancing health.

[0028] Specifically, the objective of the present invention is to develop and provide clothing and fibers that can, based on a principle different from that of conventional products, eliminate disturbances in bioelectric current, normalize blood flow, increase and activate blood flow inside the skin, improve the body fluid circulation function in the body, and have a more remarkable effect than conventional products in eliminating various physical discomfort such as stiffness in the shoulders and neck and muscle pain. [Means for solving the problem]

[0029] "Claim 1" To solve the above problems, the nanodiamond-containing garment according to the present invention is characterized in that a nanodiamond solution is attached to the body-contacting side, back side, or both sides of the garment by inkjet printing, silkscreen printing, letterpress printing, adhesive pressing, iron-on transfer, handwriting, brush writing, or impregnation dyeing.

[0030] In other words, the nanodiamond-containing garment according to the present invention is made by printing a nanodiamond solution onto the surface, back, or part or all of both sides of a garment such as a shirt using a printing method such as inkjet printing, silkscreen printing, letterpress printing, adhesive lamination, or iron-on transfer. Similarly, the nanodiamond solution may be hand-painted with a brush or other pen, or the garment may be dyed using a dyeing method that incorporates nanodiamonds.

[0031] “Claim 2” Furthermore, the nanodiamond-containing garment according to the present invention is also characterized in that the nanodiamond solution is a solvent in which nanodiamonds are blended in a weight ratio of 0.0005 wt% to 3.0 wt%.

[0032] "Claim 3" Furthermore, the nanodiamond-containing garment according to the present invention is also characterized in that the impregnation dyeing method is a direct dyeing method, a reaction dyeing method, a vat dyeing method, a color development dyeing method, a mordant dyeing method, or a disperse dyeing method.

[0033] In other words, the nanodiamond-containing garment according to the present invention becomes a nanodiamond garment when dyed by mixing a nanodiamond solution, whether by the impregnation dyeing method described above, the direct dyeing method, the reaction dyeing method, the vat dyeing method, the color development dyeing method, the mordant dyeing method, or the disperse dyeing method. However, it goes without saying that this application is not limited to the above dyeing methods, and other similar dyeing methods are also possible.

[0034] "Claim 4" Furthermore, the nanodiamond-containing garment according to the present invention is also characterized in that the inkjet printing, silkscreen printing, letterpress printing, seal pressing, iron-on transfer method, handwriting, brush writing, or impregnation dyeing method is performed using a pigment or dye obtained by mixing the nanodiamond solution with a pigment binder solution, which is an aqueous or oil-based pigment solution.

[0035] In other words, the nanodiamond-containing garment according to the present invention can be made using either a water-soluble nanodiamond solution or an oil-based nanodiamond solution, and can be mixed and dispersed in a pigment solution or dye. By attaching the nanodiamond solution to the garment using the dyeing method already described, a nanodiamond-containing garment is obtained.

[0036] "Claim 5" In addition, the nanodiamond-containing garment according to the present invention is characterized in that, in inkjet printing, silkscreen printing, letterpress printing, seal pressing, iron-on transfer method, handwriting, or brush writing, the surface of the support plate (corresponding to a backing plate) that supports the printing surface, which is the surface to which the nanodiamond solution is attached, is charged with a negative or positive charge, thereby arbitrarily adjusting the front-to-back charge of the nanodiamonds contained in the garment to a positive or negative charge.

[0037] In other words, the nanodiamonds in the nanodiamond-containing garment according to the present invention exist as individual or clustered microparticles, but the surface of these particles is polarized with weak positive and negative charges. Nanodiamond particles in a nanodiamond solution can be said to have surface charges of partially positive and negative charges on their surfaces. These individual or clustered nanodiamond particles are freely dispersed and diffused within the nanodiamond solution, but after being attached to the garment by printing or dyeing as described above and then dried and fixed, they become fixed in a certain position. Therefore, the positive and negative polarization directions of the nanodiamond particles are also freely dispersed and fixed.

[0038] However, in the inkjet printing, silkscreen printing, letterpress printing, adhesive pressing, iron-on transfer method, handwriting, or brush writing methods, by charging the surface of the support plate (for example, a member corresponding to a backing plate) that supports the printed surface, which is the surface on which the nanodiamond solution is attached to the garment, with a negative or positive charge, the front-to-back charge of the nanodiamonds contained in the garment can be adjusted to a positive or negative charge. This makes it possible to arbitrarily adjust the charge of the surface of the nanodiamond-containing garment that comes into contact with, for example, human skin, to a positive or negative charge.

[0039] As already mentioned, the surface of human skin is said to have a weak positive charge. However, by adjusting the charge of the nanodiamond particles on the surface of the nanodiamond coating according to the present invention in a specific direction, it becomes possible to provide effective electrical stimulation that penetrates deep into the skin tissue without being affected by the penetration-avoidance function of the barrier function in the stratum corneum of the skin. This weak charge can even penetrate to the dermis.

[0040] When positively or negatively charged nanodiamond particles come into contact with the skin without pressure, a bioelectric current is generated. This bioelectric current expands and promotes blood flow just beneath the skin, thus exhibiting a therapeutic effect on muscle pain such as stiff shoulders and neck, lower back pain, and knee pain, as well as headaches. Even greater effects can be expected if it is applied to an acupoint.

[0041] "Claim 6" The present invention relates to a method for manufacturing a nanodiamond-containing garment, which involves attaching and incorporating a nanodiamond solution to the human body contact side, back side, or both sides of the garment by inkjet printing, silkscreen printing, letterpress printing, seal pressing, iron-on transfer, handwriting, brush writing, or impregnation dyeing, and is characterized by performing the process in a manner in which the surface of a support plate (for example, a member corresponding to a backing plate) that supports the printed surface of the garment, which is the surface to which the nanodiamond solution is attached, is charged with a negative or positive charge, thereby allowing the front-to-back charge of the nanodiamonds contained in the garment to be arbitrarily adjusted to a positive or negative charge.

[0042] In other words, the above is presented as an independent claim for a method of adjusting the surface charge of a nanodiamond-containing garment to a constant positive or negative charge.

[0043] The nanodiamond-containing garment according to the present invention has been described above, but the present invention is not limited to the embodiments described above, and can be implemented with various modifications without departing from the spirit of the invention. All suitable forms for different applications are included in the technical concept of the present invention. Furthermore, we assert that all equivalent methods using prior art are also included in the technical concept of the present invention. [Effects of the Invention]

[0044] The nanodiamond-containing garment according to the present invention incorporates positively and negatively charged nanodiamond particles into the fibers, stabilizing bioelectric currents without compression and promoting blood flow in the wearer. The positive and negative charges of the nanodiamonds stabilize the wearer's bioelectric currents, promote blood flow, facilitate metabolism, and reduce muscle fatigue. Furthermore, since nanodiamonds are artificial minerals made of carbon and contain almost no heavy metals or impurities, they do not affect the skin.

[0045] The nanodiamond-containing garment according to the present invention can develop and provide an effective skin application or contact method that penetrates deep into skin tissue without being affected by the penetration-avoidance function of the barrier function in the stratum corneum of the skin. It can also develop and provide an effective method that allows for high absorption efficiency from the epidermis and further penetration into the dermis simply by applying, contacting, or patching the active ingredient to the skin.

[0046] In addition, the nanodiamond-containing garments according to the present invention influence nerve transmission between cells and blood flow through the positively and negatively charged nanodiamond particles, exhibiting effects such as improved bioelectricity and enhanced blood flow, making it possible to develop and provide clothing and other garments that are effective in maintaining and improving health.

[0047] Specifically, we can develop and provide clothing and textiles that can produce more significant effects than conventional products in resolving disruptions in bioelectric currents, normalizing blood flow, increasing and activating blood flow within the skin, improving the internal circulation of bodily fluids, and alleviating various physical ailments such as stiff shoulders and neck, and muscle pain.
