  Hereinafter, although the embodiment of the exothermic beauty pack of the present invention is described, the present invention is not limited to the following embodiment.

  The exothermic beauty pack of the present invention has a nonwoven fabric composed of nanofibers and a chemical exothermic layer. Nanofiber (nanofiber) is a fiber having an average diameter in the range of several nm to several thousand nm, and is usually defined as a fibrous substance having a diameter of 1 nm to 100 nm and a length of 100 times or more of the diameter. Has been. Since it is much thinner than ordinary fibers, the surface area per unit weight is extremely large. In the exothermic beauty pack of the present invention, nanofibers are arranged in a book-like form and used as a non-woven fabric, which is a cloth obtained by bonding fibers together by the fusing force of the fibers themselves or using an adhesive. The thickness of the nonwoven fabric is in the range of 1 μm to 100 μm.

  Since nanofibers are fine fibers, a nonwoven fabric composed of nanofibers is thin, light and soft, and can adhere to very small irregularities such as skin wrinkles. In addition, since the nanofiber has a very large surface area, the contact area with the skin is increased, and the skin cosmetics are also highly permeable to the skin.

  A nonwoven fabric composed of nanofibers can be produced by an electrospinning method. The electrospinning method is a method of forming a nonwoven fabric by discharging a polymer solution or a molten polymer from a number of nozzles while applying a high voltage, and depositing fibers on a long sheet. Since a polymer solution or a molten polymer is used as a raw material, almost all kinds of fiber materials can be used. In the exothermic beauty pack of the present invention, hydrophilic fibers are preferably used as the nanofibers in order to adhere to the skin. Examples of hydrophilic fibers include hydrophilic and hydrophilized materials such as hydrophilic polyurethane, hydrophilic polyvinylidene fluoride, polyvinyl alcohol, polyamide, silk, polylactic acid, and polycaprolactone.

  Of the exemplified materials, the preferred material is polyvinyl alcohol. Polyvinyl alcohol is produced by hydrolysis of polyvinyl acetate, but the solubility in water varies greatly depending on the degree of hydrolysis (saponification degree) and the degree of polymerization. Polyvinyl alcohols of different grades having different degrees of saponification and polymerization are commercially available. In addition, even when polyvinyl alcohol having a saponification degree of 100% is used as a raw material for spinning, a non-woven fabric of polyvinyl alcohol that is insoluble or hardly soluble in water or warm water by performing insolubilization treatment by acetalization when producing a nonwoven fabric composed of nanofibers Can be manufactured.

  It is considered that the adhesion required for the exothermic beauty pack is further enhanced by the fact that the surface of polyvinyl alcohol, which is a non-woven material, dissolves in water to some extent. Therefore, when using commercially available polyvinyl alcohol as the material for the nonwoven fabric, it is preferable to select from a grade having different saponification degree and polymerization degree in consideration of solubility in water.

  Further, insolubilization treatment by acetalization of polyvinyl alcohol is performed by, for example, electrospinning, using a material obtained by adding a crosslinking agent to a polyvinyl alcohol solution as a raw material, and discharging it from a number of nozzles while applying a high voltage to form a fiber on a long sheet Can be carried out by a process of treating with hydrochloric acid gas after depositing and forming a nonwoven fabric. The degree of insolubilization varies depending on the amount of crosslinking agent added and the treatment time with hydrochloric acid gas. As the crosslinking agent, for example, glutaraldehyde can be used. Unreacted glutaraldehyde can be removed using, for example, glycine.

The degree of insolubilization can be measured, for example, by a test method in which the solubility is measured by immersing in distilled water at room temperature for 1 hour. The solubility can be measured by weight reduction rate or visual inspection with a microscope. In a test for examining the degree of insolubilization using glutaraldehyde, the insolubility was insufficient when the addition amount of glutaraldehyde was 5% by weight with respect to polyvinyl alcohol and the treatment time with hydrochloric acid gas was 10 seconds. When the addition amount of glutaraldehyde was 10% by weight or more, preferably 15% by weight or more with respect to polyvinyl alcohol, and the treatment time with hydrochloric acid gas was 10 seconds, a preferable degree of insolubilization was obtained. The upper limit of the addition amount of the crosslinking agent is a theoretical amount for acetalizing all hydroxyl groups of polyvinyl alcohol with the crosslinking agent.
The insolubilization treatment of polyvinyl alcohol can also be performed by heat treatment (for example, conditions of 180 ° C. for 30 minutes).

  Some of the chemical heat generation layers use a chemical reaction that generates heat by causing an oxidation reaction with oxygen in the air, and some chemically generate heat by reacting with water to release heat of hydration. Forms include a film heating layer, a sheet shape in which a sponge is filled with a heat generating composition that chemically generates heat, and a bag-shaped heat generation in which a chemically generating heat generating composition is sealed in a flat packaging bag having air permeability. There is a body.

[Embodiment 1]
As shown in FIG. 1, the exothermic beauty pack 101 of Embodiment 1 has a structure in which a chemical heating layer 300 is laminated as a coating film heating layer 301 on a nonwoven fabric 200 made of nanofibers.

The chemical heat generation layer 300 of the coating film heat generation layer 301 constituting the exothermic beauty pack 101 of Embodiment 1 can be exemplified by a chemical composition of a heat generation composition that generates heat. As the exothermic composition, an exothermic substance, a carbon component, an oxidation assistant such as a metal chloride, and water as a main component can be used. As the exothermic substance, iron powder, zinc powder, aluminum powder, magnesium powder or an alloy powder composed of two or more of these metals that generate heat when oxidized by air, and further, two or more of these are mixed. Mixed metal powder etc. are used, but among these metal powders, iron powder that is most excellent in terms of safety, handleability, cost, storage stability and stability is used. desirable. Examples of the carbon component include carbon black, graphite or activated carbon. Examples of metal chlorides include alkali metal chlorides such as sodium chloride and potassium chloride, and alkaline earth metal chlorides such as calcium chloride and magnesium chloride.
The thickness of the coating heat generating layer 301 is preferably in the range of about 5 μm to 5 mm in order to maintain the calorific value without impairing the flexibility of the nonwoven fabric 200.

  The component ratio of the exothermic composition is preferably 40 to 75% by weight of the exothermic substance, 1 to 10% by weight of the carbon component, 1 to 10% by weight of metal chloride and 10 to 40% by weight of water. The exothermic composition may be blended in the paint as it is, or may be encapsulated in microcapsules to generate heat by breaking the wall film of the microcapsules during use.

  As a paint, since it is used for a human body, it is preferable to use a paint that is highly safe and can form a soft coating film that is oily and excellent in air permeability. For example, a paint using plant-derived vegetable oil and a natural solvent is preferably used.

  The exothermic beauty pack of Embodiment 1 in which the chemical exothermic layer 300 is laminated as the coating exothermic layer 301 on the non-woven fabric 200 composed of nanofibers by applying a paint mixed with the exothermic composition to the non-woven fabric. Can be manufactured. Although not shown in the drawings, since the heat generating layer 301 starts to generate heat when exposed to air, the exothermic beauty pack of the present invention is stored in an air-tight sealing bag and sealed when used. Remove from bag and use.

  The exothermic beauty pack 101 of Embodiment 1 is a beauty in which the non-woven fabric 200 composed of nanofibers has high adhesion to the face, good touch, is not easily removed, and has high absorption efficiency of skin cosmetics to the skin. It has the best features for the pack. The chemical heat generation layer 300 laminated on the nonwoven fabric 200 is the coating film heat generation layer 301. Since it is extremely thin, a large amount of heat generation cannot be expected, but it does not interfere with the adhesion of the nonwoven fabric 200 composed of nanofibers. A short-time thermal effect can be exhibited.

[Embodiment 2]
As shown in FIG. 2, the exothermic beauty pack 102 of Embodiment 2 is a sheet-like heating element 302 in which a sponge 200 is filled with a exothermic composition that chemically generates heat on a nonwoven fabric 200 composed of nanofibers. Have a laminated structure.

  The sponge is a porous body having open cells, and examples of the sponge include cellulose sponge, urethane sponge, polyethylene sponge, and rubber sponge. Since the porosity and the size of the voids depend on the production method, they can be appropriately selected. The exothermic composition can be filled in the gaps of the sponge by a method in which the exothermic composition is suspended in a solution, absorbed in the sponge, and then dried. Further, it can be produced by applying a paste-like exothermic composition onto a sponge. The thickness of the sponge is preferably in the range of about 0.2 to 5 mm in order to maintain the calorific value without impairing the flexibility of the nonwoven fabric 200. The exothermic beauty pack of Embodiment 2 can be manufactured by bonding the sheet-like heating element 302 filled with the exothermic composition to the nonwoven fabric 200 composed of nanofibers with an adhesive.

  The exothermic beauty pack 102 of Embodiment 2 is a beauty in which the non-woven fabric 200 composed of nanofibers has high adhesion to the face, good touch, is not easily removed, and has high absorption efficiency of skin cosmetics into the skin. It has the best features for the pack. The chemical heating layer laminated on the nonwoven fabric 200 is a sheet-like heating element 302 filled with a heating composition that chemically generates heat in the voids of the sponge, and is flexible and can secure a certain amount of heating. Therefore, the thermal effect can be exhibited without hindering the adhesion of the nonwoven fabric 200 composed of nanofibers.

[Embodiment 3]
As shown in FIG. 3, in the exothermic beauty pack 103 of Embodiment 3, a flat packaging bag is formed of a nonwoven fabric 200 composed of nanofibers and a breathable sheet 310, and powder is contained in the flat packaging bag. A bag-like heating element 303 in which a heat-generating composition 320 in the form of a bag is enclosed.

The sheet 310 having air permeability may be any sheet as long as it can supply air to the exothermic composition 320 and enclose the exothermic composition 320, and examples thereof include woven fabric and non-woven fabric. In order to form the non-woven fabric 200 composed of nanofibers and a flat packaging bag, the sheet 310 and the non-woven fabric 200 composed of nanofibers are cut into substantially the same shape, and the exothermic composition 320 is composed of nanofibers. The sheet 310 is stacked with a predetermined thickness, and the sheets 310 are overlapped, and the entire edges of the overlapping edges of the sheet 310 and the nonwoven fabric 200 are joined to each other. The joining method can be performed by sewing, an adhesive, heat welding, or ultrasonic welding. Since the exothermic composition 320 is sealed in a bag in this embodiment, in addition to the above-described exothermic agent that generates heat when oxidized by air, an exothermic agent that generates heat by hydration heat in contact with water is also used. be able to. For example, calcium oxide can be exemplified. When calcium oxide is used, at least the inner surface of the flat packaging bag needs to be impermeable.
The thickness of the bag-like heating element 303 is preferably in the range of about 100 μm to 5 mm in order to maintain the calorific value without impairing the flexibility of the nonwoven fabric 200.

  The exothermic beauty pack 103 of Embodiment 3 can enclose a relatively large amount of the exothermic composition 320 in a flat packaging bag. For example, the amount of the exothermic composition enclosed can be adjusted so that the temperature of the part in contact with the face can be heated at 35-50 ° C. for 20-40 minutes. Since a flat packaging bag in which powder is encapsulated is used as the heat generating layer, the flexibility is somewhat impaired, but since the amount of heat generation can be increased, a long-time heating effect can be expected. Therefore, the non-woven fabric composed of nanofibers has a large contact area with the skin, and can promote the function of the skin cosmetic material having excellent permeability to the skin.

[Embodiment 4]
As shown in FIG. 4, in the exothermic beauty pack of Embodiment 4, a chemical heating layer 300 is laminated on a nonwoven fabric 200 composed of nanofibers, and the microcapsule 400 is placed on the nonwoven fabric 200 composed of nanofibers. It has a woven structure. As the chemical heating layer 300, any of those used in Embodiments 1 to 3 can be used.

  Examples of the core substance of the microcapsule 400 include skin cosmetics such as moisturizing ingredients, perfumes, poultices, hot spring ingredients contained in hot springs, and the like. Among them, the moisturizing component is useful as a component that promotes the moisturizing effect due to the thermal effect. It can be used alone or in combination of two or more.

  The wall film of the microcapsule 400 is provided with a function of sealingly storing the core material and releasing the core material when necessary. For example, if the core substance is oil-soluble, it is possible to select a water-soluble material that dissolves in the skin lotion when liquid lotion is included in the nonwoven fabric composed of nanofibers. In addition, a temperature-sensitive material can be selected that dissolves when the chemical heating layer generates heat and is heated. Examples of such temperature sensitive materials include synthetic resins and waxes having a softening point at a low temperature of about 40 ° C., for example. When microcapsules that release a core substance when heated to a certain temperature can be used to supply chemicals, skin cosmetics, etc. when the thermal effect is enhanced, a high cosmetic effect can be exhibited. There are various manufacturing methods for microcapsules, such as a phase separation method, a melt dispersion cooling method, and an interfacial polymerization method, depending on the type of core material and the type of wall material.

  The particle size of the microcapsules is not particularly limited, and can be woven into a nonwoven fabric composed of nanofibers from several hundred nm to several hundred μm. In order to improve the permeability to the skin, a size called a nano-level nanocapsule of 300 to 700 nm is preferable. When it is a nanocapsule, it can reach the dermis layer through the stratum corneum and the epidermis of the skin. Therefore, the cosmetic effect can be enhanced as compared with the normal size microcapsules.

  As a method of weaving microcapsules into a non-woven fabric composed of nanofibers, when producing a non-woven fabric composed of nanofibers by electrospinning, the microcapsules are mixed into the raw polymer solution or molten polymer. And a method of weaving a raw material solution not containing microcapsules from a large number of nozzles while applying a high voltage, and weaving into a nonwoven fabric by spraying microcapsules when fibers are deposited on a long sheet There is.

  The exothermic beauty pack of the present invention can be formed into a patch type such as a circle, an ellipse, a rectangle, or a U shape, or a mask shape obtained by punching the mouth, eyes, or nose according to the shape of the face. When a large area is covered with one exothermic beauty pack of Embodiment 3, quilting may be performed so that the exothermic composition 320 in the flat packaging bag is not biased.

  The exothermic beauty pack of the present invention is generally distributed in a packaging bag that does not allow air to pass in order to store the exothermic composition. Take out from the bag at the time of use, soak the skin cosmetic into the non-woven fabric composed of nanofibers and affix it to the necessary part of the face. Affixed in close contact. Since nanofibers are extremely thin, they adhere to very small irregularities such as skin wrinkles and are difficult to fall off. In addition, since the nanofiber has a very large contact area with the skin, and the area through which the skin cosmetic penetrates the skin from the contact portion between the skin and the nanofiber is large, the permeation speed is high and the cosmetic effect is excellent. On the other hand, immediately after taking out from the bag, the exothermic composition starts to generate heat, warms the non-woven fabric composed of nanofibers and the skin cosmetics soaked in the non-woven fabric, and the thermal effect that warms the skin opens pores, As a result of the swelling of the skin due to the moisture effect, the skin cosmetic penetrates well into the skin. At this time, in the exothermic beauty pack of Embodiment 4, the core substance in the inside is released from the microcapsules woven into the nanofibers, and the cosmetic effect can be promoted.

  After a certain period of time, when the exothermic beauty pack is peeled from the face, the oil and fat on the skin and old keratin adhere to the nonwoven fabric composed of nanofibers and remove them from the skin, making the skin healthy be able to. Nanofiber is highly effective in removing these oils and fats and old keratin, and is excellent in cosmetic effect.

[Experimental example]
This experimental example is an experimental example showing that the degree of insolubilization in water of a nanofiber nonwoven fabric made of polyvinyl alcohol can be adjusted by adjusting the degree of insolubilization treatment by acetalization.

1. Sample preparation (1) Sample 1
Electrospinning by adding glutaraldehyde (concentration to polymer in final polymer solution for electrospinning: 35 wt%) to polyvinyl alcohol solution (PVA-217 of Kuraray Co., Ltd., solvent: distilled water, concentration: 10 wt%) A polymer solution was prepared. Then, electrospinning was performed using this polymer solution for electrospinning to produce a nanofiber nonwoven fabric (average fiber diameter: 500 nm). Then, the nanofiber nonwoven fabric was insolubilized by bringing it into contact with hydrochloric acid gas for 10 seconds to obtain a nanofiber nonwoven fabric according to Sample 1.

(2) Sample 2
A nanofiber nonwoven fabric was prepared in the same manner as Sample 1 except that the concentration of glutaraldehyde with respect to the polymer in the final polymer solution for electrospinning was changed to 5 wt%, and the nanofiber nonwoven fabric according to Sample 2 was obtained. .

2. Evaluation Method Each sample (Samples 1 and 2) was immersed in distilled water at room temperature for 1 hour, and then a scanning electron micrograph was taken for each sample.

3. Evaluation Results FIG. 5 is a view showing a scanning electron micrograph after each sample is immersed in distilled water. FIG. 5A is a diagram showing a scanning electron micrograph of Sample 1, and FIG. 5B is a diagram showing a scanning electron micrograph of the nanofiber nonwoven fabric of Sample 2. FIG.

  As can be seen from FIG. 5, in sample 2 (sample in which insolubilization treatment was not sufficiently performed), the degree of insolubility in distilled water is low, and the shape of the nanofiber is considerably collapsed, whereas sample 1 (insolubilization) It was found that in the case of a sufficiently processed sample, the degree of insolubility in distilled water was high, and the shape of the nanofiber was hardly broken.

  From this, it was found that the degree of insolubilization of the nanofiber nonwoven fabric in water can be adjusted by adjusting the degree of insolubilization treatment by acetalization for the nanofiber nonwoven fabric made of polyvinyl alcohol.

  Thereby, by adjusting the degree of insolubilization treatment by acetalization, it becomes possible to form a nonwoven fabric composed of nanofibers in a state where nanofibers are appropriately dissolved, and is composed of nanofibers and adhesion to the skin. It is possible to construct a heat-generating beauty pack that combines the effects of adopting a non-woven fabric (high adhesion to the face, good touch, difficult to fall off, and high absorption efficiency of skin cosmetics into the skin) It becomes.

  Unreacted glutaraldehyde can be removed using, for example, glycine.

  The exothermic beauty pack of the present invention is used for facial beauty and can be used in the beauty industry and the medical field.
