Description

[Detailed Description of the Invention] [Industrial field of application] The present invention utilizes a heat retaining property of aluminum to attach it to a muscle sore part of the body and warm it to heat it to accelerate recovery and a heat retaining sheet. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat retaining tool for clothing and footwear that has a storage part that contains a sheet-like material.

[Conventional technology]

Aluminum foil with a thin coating of aluminum with a thickness of several tens of μ, aluminum foil laminated on plastic film, or aluminum powder vapor-deposited aluminum adhesive tape warms the sore muscles of the body to relieve pain and accelerate recovery. It is used as a heat insulating material.

This is a high heat-retaining power due to the heat-reflecting property of aluminum, which alleviates the pain of muscle pains (hereinafter referred to as affected parts) such as low back pain, shoulder pain, and elbow pain caused by coldness of the body and overuse of muscles. This is because it is effective.

However, since the aluminum foil is thin and easy to tear as it is, if you apply it directly on the skin of the affected area, sweat will accumulate and the affected area will cool rather, so attach the aluminum foil to the cloth and apply the cloth surface to the affected area. I was doing.

Also, in the case of the aluminum adhesive tape, the cloth surface was similarly applied to the affected area after being adhered to the cloth.

[Problems to be solved by the device]

With the above-mentioned conventional aluminum foil, even if you are careful when sticking it on the backing cloth, it is easy to tear, it fails and wastes,
It was hard to stick and it took a lot of time to worry about it. Moreover, when I moved my body when using it, it made a jarring sound and was uncomfortable.
Further, if the aluminum foil is torn during use, the heat retention performance will eventually decrease, and the desired therapeutic effect may not be exhibited.

On the other hand, although it is hard to tear with aluminum adhesive tape,
After all, since the tape width of the commercial product is not made for this purpose, it is too narrow to cover the affected area, and it is inconvenient and time consuming to cut and paste several times. It was

An object of the present invention is to solve the above-mentioned conventional problems, to be easily attached to an affected area, to be excellent in wearing feeling during use, to be free from discomfort during use, and to be able to maintain heat retention performance for a long time. An object of the present invention is to provide a heat-retaining tool for clothing and footwear, which has a sheet-like article for use and a storage section containing the sheet-like article for heat retention.

[Means for Solving the Problems]

The above-mentioned purpose is to apply a resin coating in which aluminum powder or fine aluminum foil pieces are dispersed on one surface of a thermoplastic resin sheet, and to bond the coated surface and a base material having elasticity and moisture permeability to heat insulation. The heat-insulating sheet-like article, the heat-insulating sheet-like article in which the aluminum vapor deposition layer is interposed between the thermoplastic resin sheet and the base material having elasticity and moisture permeability.

Further, the above-mentioned object is to provide a warming tool for clothing having a storage section in which each of the above-mentioned warming sheet-like objects is built-in and a heat-retaining tool for footwear having a warming section in which each of the above-mentioned warming sheet-like objects is built-in. To be achieved.

[Action]

When using the heat insulating sheet of the present invention, cut the heat insulating sheet according to the size of the affected area so that the base material side having elasticity and moisture absorption is directly contacted with the affected area. To do. Therefore, it is not necessary to perform a labor-intensive and time-consuming operation before attaching the heat-insulating sheet material to the affected area.

The affected part perspires due to the heat retention of the aluminum powder, the fine aluminum foil pieces, or the aluminum vapor deposition layer. At this time, since the base material has a moisture-absorptive property, it absorbs sweat and prevents the affected part from being cold. Moreover, since the base material has elasticity, the heat-insulating sheet-like material attached to the affected area can respond to the movement of the body.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

1 to 5 are cross-sectional views showing examples of the heat insulating sheet material of the present invention.

In FIG. 1, a resin coating material 6 in which aluminum powder or aluminum foil pieces 3 are dispersed is applied to one surface of a thermoplastic resin sheet 5, and the coating material surface and a base material 1 having elasticity and moisture permeability are adhesive. It is laminated via layer 2.

Examples of the stretchable and moisture-absorptive material that constitutes the substrate 1 include materials such as knits, woven fabrics, non-woven fabrics, papers, and plastic sheets, and can be arbitrarily selected according to the application. Here the plastic sheet is non-foamed,
Either closed cell or open cell foam can be employed.

The composition of the adhesive constituting the adhesive layer 2 should be arbitrarily selected depending on the respective components of the base material 1 and the resin coating material 6. For example, when the base material 1 is a woven fabric such as a knitted fabric. , Vinyl chloride-vinyl acetate copolymer resin-based paint is effectively used.

When the adhesive layer 2 is formed, any of known coating methods such as a gravure roll coating method, a bar coating method, a doctor knife coating method, and a rebase roll coating method can be used for the base material 1.

The average particle size of the aluminum powder or aluminum foil pieces mixed in the resin coating material 6 is preferably about 5 to 150 μm.

If the average particle size is smaller than 5 μ, the heat reflectivity by aluminum is poor, while if the average particle size is larger than 150 μ, the aluminum powder and the fine aluminum foil pieces 3 are evenly applied to the resin coating 6 surface. Difficult to distribute. The amount of aluminum powder or aluminum foil pieces mixed in the resin coating 6 depends on the heat retention performance and the resin coating 6
Considering workability in coating and the like, it is desirable that the content ratio in the solid content of the resin coating material 6 is 10 to 50% by weight.

Content of aluminum powder or aluminum foil piece 3 is 1
When the content is less than 0% by weight, the heat retention performance is not sufficient, while when the content of the aluminum powder or the aluminum foil piece 3 is more than 50% by weight, the viscosity of the coating liquid of the resin coating 6 is too high and the coating workability is high. Deteriorates, and it becomes difficult to form the desired 6 layers of resin paint.

The thickness of the resin coating 6 is preferably in the range of 0.5 μ to 100 μ. When the thickness of the resin coating 6 is less than 0.5 μ, it becomes difficult to uniformly distribute the aluminum powder or the aluminum foil pieces 3 on the surface of the layer, and it becomes difficult to exhibit desired heat retention performance. When the thickness of the resin coating 6 is thicker than 100 μ, the resin layer combined with the thermoplastic resin sheet 5 becomes thick as a whole, and the weight of the heat-insulating sheet-like material becomes large, resulting in insufficient feeling of attachment to the affected area. Becomes

The thermoplastic resin sheet 5 plays a role of protecting the resin coating 6 containing the aluminum powder or the aluminum foil pieces 3, and when forming a layer of the resin coating 6, a paste-like liquid is applied to the thermoplastic resin sheet 5. Since it is applied, it is necessary to have a thickness that does not hinder this work process. Therefore, it is desirable to reduce the thickness of the thermoplastic resin sheet 5 within a range in which physical properties such as strength sufficient to maintain this workability are maintained.

The thermoplastic resin sheet 5 is formed by a method such as a calendering method, an extrusion method, or a coating method. A pigment is appropriately selected and attached according to the application of the heat insulating sheet material, and a desired color,
For example, it can also be used by coloring it to the skin color.

Laminate the aluminum vapor deposition film 7 via
An example is shown in which the base material 1 and the aluminum vapor deposition film are laminated on the base material 1 with the adhesive layer 2 previously formed by subbing. In this embodiment, it is desirable that the thickness of the aluminum vapor deposition film 7 is approximately 1 μm to 5 μm.

The aluminum vapor-deposited film 7 can be formed into an extremely thin film by vapor deposition, has relatively flexibility, and is laminated in a state of being interposed inside the heat-insulating sheet-like material. Less likely to break like aluminum foil. In this embodiment, it is preferable to use polyester-based, acrylic-based and vinyl acetate-based adhesives for the adhesive layers 2 and 2 located on both sides of the aluminum vapor deposition film 7 in consideration of adhesiveness to aluminum.

The heat insulating sheet shown in FIG. 3 is laminated with the base material 1 on which the aluminum vapor deposition layer 8 is formed by directly vapor-depositing aluminum on one surface of the thermoplastic resin sheet 5, and the adhesive layer 2 is previously formed by subbing. It was done. The thickness of the aluminum vapor deposition layer 8 in this embodiment may be the same as the thickness of the vapor deposition film 7 in FIG.

FIG. 4 shows a large number of small holes 9 formed in the thickness direction of the heat insulating sheet. In FIG. 4, the small holes 9 are formed in the heat-insulating sheet-like article provided with the thermoplastic resin sheet 4 in which the aluminum powder or the aluminum foil pieces 3 are dispersed. The same can be applied to the sheet material in the figure. It is desirable that the inner diameter of the small hole 9 is about 10 μ to 100 μ.

In the heat insulating sheet having the small holes 9 formed as described above, the air permeability is extremely high, and for a person with a large amount of sweating, when the heat insulating sheet is pasted on the affected area, the heat insulating sheet is prevented from becoming uneven. It becomes possible.

FIG. 5 shows the pressure-sensitive adhesive layer 10 on the surface of the base material 1 side of the heat insulating sheet.
It shows an example in which the release material 11 is laminated via the.
As the release material 11, in addition to so-called release paper, a release material film made of polyester resin or the like can be used.

Further, to the pressure-sensitive adhesive layer 10, a soothing agent containing so-called salicylic acid, methyl salicylate, glycol salicylate or the like, and if necessary a poultice containing an auxiliary agent such as menthol may be added.

In the case of the heat-insulating sheet-like material shown in FIG. 5, the release material 11 may be peeled off from the heat-insulating sheet-like material when it is attached to the affected area, and the surface of the adhesive layer 10 may be attached to the affected area. In this case, the pressure-sensitive adhesive layer 10 ensures that the heat-retaining sheet-like material is attached to the affected area, and there is less risk that it will separate from the affected area during use. When the pressure-sensitive adhesive layer 10 contains a poultice, the therapeutic effect on the affected area is improved by the synergistic effect of the active ingredient of the drug and the heat retaining effect.

Further, the pressure-sensitive adhesive layer may be provided on the thermoplastic resin sheet side instead of the substrate surface side.
