BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below. The structure used in the present invention, polyester-based, polyamide-based, polyacrylonitrile-based, polyethylene-based, polypropylene-based, polybutylene terephthalate-based, polytetramethylene terephthalate-based, polyurethane-based, polyphenylene sulfide-based synthetic fibers, rayon, Chemical fibers such as acetate, cotton, hemp,
It is a structure composed of a knitted fabric, a woven fabric, a non-woven fabric, a fleece or the like made of natural fibers such as silk, wool, and feathers, or a mixed material thereof.

The highly hygroscopic particles (also referred to as highly hygroscopic / water-absorbing exothermic particles) of the present invention are not particularly limited in terms of chemical structure as long as they are particles that exhibit exothermicity when absorbing moisture or absorbing water. . For example, various organic type fine particles such as inorganic type or hygroscopic polyurethane type such as hygroscopic silica, polyamide type, polyester type and polyacrylate type can be applied, but high hygroscopic / water absorbing exothermic organic fine particles are particularly preferable. . For example, a polystyrene-based, polyacrylonitrile-based, polyacrylic acid ester-based, or polymethacrylic acid ester-based vinyl polymer having at least one of a sulfonic acid group, a carboxylic acid group, a phosphoric acid group, or a metal salt thereof. Crosslinked polymer microparticles having certain hydrophilic groups and crosslinked with either divinylbenzene, triallyl isocyanate or hydrazine are preferred.

The particle size of the highly hygroscopic fine particles is preferably as small as possible from the viewpoint of moisture absorption / water absorption heat generation rate / heat generation efficiency, uniform adhesion and texture, and an average particle diameter of less than 2 μm is more preferable.

Examples of the method for applying the highly hygroscopic fine particles of the present invention include a method of directly kneading into a fiber, a film and / or a resin layer, and a method of adhering to the surface layer of a knitted fabric, a woven fabric, a non-woven fabric and a fleece via a binder resin. However, moisture absorption /
From the viewpoint of water absorption heat generation rate / heat generation efficiency, the latter adhesion method via a binder resin is preferable.

As the binder resin, a usual impregnation method,
Silicone, urethane, acrylic, polyester, polyamide, polyethylene oxide, and other resins applicable to the padding method, coating method, and spray method include, but are not particularly limited to, hydrophilicity, that is, hygroscopicity, water absorption, A type that has excellent moisture permeability, does not impair the hygroscopicity and water absorption of the highly hygroscopic / water-absorbing exothermic particles, and has an excellent binder function that can effectively bond and fix the highly hygroscopic / water-absorbing exothermic particles and the structure. preferable. As a particularly preferable hydrophilic resin binder, as the hydrophilic segment, polyalkylene oxide addition type, sulfonate,
Polar hydrophilic group type such as carboxylate, hydrophilic silicone resin with amide modification, hydrophilic urethane resin,
Examples thereof include hydrophilic polyamide resins and hydrophilic polyethylene oxide resins, which have high hygroscopicity and moisture permeability of the resin itself and do not impair water absorption. The moisture permeability of the resin as used herein means the moisture permeability in a non-porous film state. Even in the case of a resin having a high moisture permeability expressed in a microporous film, a binder resin having a low hygroscopicity and a low water absorptivity of the resin itself masks and lowers the excellent moisture absorption / heat absorption heat generation property of the high moisture absorption / water absorption heat generation fine particles. Further, in order to improve durability in the system of these highly hygroscopic / water-absorbing exothermic particles and hydrophilic resin binder,
Isocyanate-based, methylol-based, ethyleneimine-based,
Various crosslinking agents such as polyfunctional aziridinyl-based and metal salt-based crosslinking agents may be used in combination within a range that does not reduce the original moisture absorption / water absorption.

The compounding ratio of the highly hygroscopic / water-absorbing exothermic fine particles and the hydrophilic resin in the present invention and the amount of these adhering greatly affect the hygroscopic / water-absorbing exothermicity. The compounding ratio of the highly hygroscopic / water-absorbing exothermic fine particles and the hydrophilic resin is slightly different depending on the hydrophilic level of the hydrophilic resin, but normally, the compounding ratio of 1/1 to 19/1 is preferably used, and more preferably 10/1 to 19/1. The mixing ratio of
More preferably, the smaller the compounding ratio of the hydrophilic resin, such as the compounding ratio of 15/1 to 19/1, the better the moisture absorption /
Water absorption and exothermicity can be exhibited. However, when the hydrophilic resin is extremely small, or when the hydrophilic resin is not used together, the abrasion resistance of the highly hygroscopic / water-absorbing exothermic particles adhered to the surface of the structure is lowered and the particles easily fall off. On the other hand, if the blending ratio of hydrophilic resin is high, even in the case of hydrophilic resin, there are many cases where the original moisture absorption / water absorption of high heat-absorption / water-absorption exothermic particles is obstructed. The heat generation rate and heat generation amount are extremely reduced. When the moisture absorption / water absorption of the hydrophilic resin is equal to or higher than that of the high moisture absorption / water absorption exothermic particles, the compounding ratio of the hydrophilic resin can be increased.

The exothermicity of the moisture-absorbing / water-absorbing exothermic structure of the present invention is based on the heat of adsorption reaction generated when the substance absorbs moisture or absorbs water, and the highly hygroscopic / water-absorbing fine particles and the combined hydrophilic resin contained in the structure. It depends on the hygroscopic ability and / or the water absorbing ability of the binder and the adhered amount. That is, the higher the moisture absorption / water absorption fine particles and the finer the hydrophilic resin binder having a higher moisture absorption and water absorption level, the greater the heat generation due to the adsorbed moisture, the faster the heat generation rate, and the longer the heat generation retention time. In addition, since moisture absorption / water absorption is possessed by the structure base material alone, in order to realize more effective moisture absorption / water absorption exothermicity,
The hygroscopicity of the water-absorbing exothermic particles is preferably 25% or more, more preferably 40% or more. Further, the combined hydrophilic resin preferably has at least 3 to 50% hygroscopicity which does not impair the hygroscopicity / water absorption of the above-mentioned hygroscopic / water-absorbing exothermic particles as much as possible. That is, in order to obtain effective moisture absorption / water absorption exothermicity, the structure having a high degree of moisture absorption / water absorption exothermicity of the present invention has a low moisture absorption rate as much as possible, and more preferably a state close to complete drying (absolute dryness). Moreover, it is important to store it in a closed state with no air permeability. On the other hand, the structure that has adsorbed moisture at a saturated moisture absorption rate or higher and has completed heat generation is cooled by heat radiation and drops to the initial temperature, but if it is dried again to remove the adsorbed water, the original excellent moisture absorption / It is possible that the water absorption exothermicity is re-developed.

The moisture absorption exothermicity in the gas phase heats up at an appropriate rate and maintains the exothermicity for a relatively long time, while the water absorption exothermicity in the liquid phase gives a rapid exothermicity, while the adsorbed water If the amount is too large, the remarkable heat generation effect may not be obtained, so it is important to control the amount of attached water. In particular, the water absorption and heat generation function of the present invention is effective when rapid heating is desired as in the use of acupuncture and moxibustion of the present invention.

In the moisture-absorbing / water-absorbing exothermic acupuncture treatment patch of the present invention, it is preferable to interpose a metal sheet having a pressure-sensitive adhesive and a protrusion on the surface in contact with the skin. This is because when heating acupuncture and moxibustion / water absorption, in the heating patch fabric for exothermic acupuncture and moxibustion treatment, water is dripped, but when the dripped water directly touches the skin, stuffiness or the like occurs, This is because comfort is reduced. The type of metal sheet is not particularly limited, but an aluminum sheet is preferable because it has good thermal conductivity, is lightweight, and metal allergy is unlikely to occur. Any adhesive may be used as long as it is less likely to cause skin irritation. Further, as for the protrusion, it is for further stimulating the pot and improving the therapeutic effect. For the material,
A thermoplastic resin or the like may be used, but it is preferably made of metal. The size of the protrusion is preferably 1.0 mm or less in diameter and 2 mm or less in length. this is,
When the diameter is 1.0 mm or more and the length is 2 mm or more, the protrusions are too large and the skin may be damaged more than necessary.

According to the present invention, the type of highly hygroscopic / water-absorbing exothermic fine particles and the amount of adhesion are optimized, and the structure adhered through a proper hydrophilic resin binder has a maximum temperature rise of 3 ° C. during moisture absorption and / or water absorption. As described above, preferably 4 ° C. or higher, more preferably 5 ° C. or higher, or the maximum temperature rise during water absorption is 8 ° C. or higher, and the heat generation retention time during moisture absorption is 3
Moisture absorption / water absorption heat generation rate, such as 0 minutes or more, heat generation retention time during water absorption is 30 seconds or more, more preferably 1 minute or more,
In terms of total heat generation performance such as heat generation amount and heat retention time, it is possible to obtain a medical heating patch material having excellent moisture absorption / water absorption exothermic properties which has never been seen before and which is suitable for acupuncture and sprain treatment.
