Description

  The present invention relates to clothing and parts to be worn on the body, and more particularly to a body wear tool having functions such as fatigue recovery and blood circulation promotion.

Activated charcoal such as charcoal and bamboo charcoal is known for its effects such as odor absorption, dehumidification and antibacterial effects, and has been used for these purposes for a long time. In addition, activated carbon has been found to have various health effects on a living body represented by far-infrared radiation, and its utilization is attracting attention.
The following Patent Document 1 discloses that the utility of the activated carbon can be enhanced by using a charcoal made from a woven fabric made of Japanese paper as a raw material.

  On the other hand, negative ions have been reported to be effective in relieving fatigue. Negative ions are generated not only in various health products such as wrist rings using tourmaline ore, but also in household appliances such as dehumidifiers and air conditioners. Features have been developed. In addition to the tourmaline, ores such as barleystone are known as substances that generate negative ions. A product in which these ores are powdered and contained in a resin has been developed.

JP2003-306850 "Carbide and sheet product thereof"

However, in the configuration in which fine particles that generate negative ions are encapsulated in the resin, there is a problem that the action of the negative ion generating material becomes weak.
Further, it is recognized that the carbide of Patent Document 1 has a higher effect of making use of charcoal than using charcoal products such as charcoal as it is, but this is the effect of activated carbon, and the amount of negative ions generated from the activated carbon is negative ions. It is considered that the effect of the generation of negative ions is hardly expected with the carbide of Patent Document 1 because the amount is much smaller than that of a substance specialized for generation.

  In order to add the effect of activated carbon in addition to the effect of generating negative ions to this problem, it is conceivable to mix fine activated carbon powder into the resin composition containing the negative ion generating substance. There is a problem that the contact area between the activated carbon surface and air, gas, etc. becomes extremely low, and the characteristics of the activated carbon cannot be fully utilized.

This invention is made | formed in view of the said subject, and the objective of this invention is providing the body wearing tool which can solve the said subject.
An example of a specific purpose is as follows.
(A) Provided is a body wearing device that can obtain an effect such as a hot spring bath in addition to a preferable effect on a living body of activated carbon.
(B) To provide a body wearing device capable of increasing the amount of negative ions emitted.
(C) To provide a body wearing tool that can be easily worn even in places where it is difficult to attach ankles or arches to a health article using the sheet-like material, and can have a favorable influence on the body.
(D) To provide a body wearing tool for a joint that can easily obtain effects such as blood circulation promotion and pain relief even at a joint with a large body movable range.
The problems of the invention other than those described above and the means for solving them will be described in detail in the description in the specification to be described later.

Although the present invention can be expressed in many ways, for example, typical ones are configured as follows.
The body wearing device of the first invention is formed by knitting yarn made of natural bast fibers, and arranging a carbonized fabric layer obtained by carbonizing a fabric spread in a planar shape and fine ore particles containing radioactive material in a planar shape. It is comprised from the sheet-like material containing the radioactive substance layer which processed, The said sheet-like material was processed into the shape which can be mounted | worn with a body, It is characterized by the above-mentioned.
The body wearing device of the second invention is a radioactive material in which a fabric carbonized material layer obtained by knitting a thread made of Japanese paper and carbonizing a fabric spread in a planar shape and a fine granule of ore containing a radioactive substance is disposed in a planar shape. It is comprised from the sheet-like material containing a substance layer, The said sheet-like material was processed into the shape which can be mounted | worn with a body, It is characterized by the above-mentioned.
The body wearing device according to the third aspect of the present invention is a carbonaceous material layer formed by spreading a activated carbon of a plant into particles having a particle diameter of 1 μm to 1 mm and then spreading into a planar shape, and a fine ore granular material containing a radioactive substance in a planar shape. It is comprised from the sheet-like material containing the radioactive substance layer arrange | positioned in this, The said sheet-like material was processed into the shape which can be mounted | worn with a body, It is characterized by the above-mentioned.

According to a fourth invention, in the invention according to any one of the first to third inventions, the radioactive material layer has a formation part and a non-formation part in a plane, and the area of the formation part occupying the entire area The ratio is 0.3 to 0.6, and the air permeability is improved by the non-formed part.
According to a fifth invention, in the invention according to any one of the first to fourth inventions, the radioactive material layer is fixed to one surface side of the base material having good air permeability, and the carbonization is performed on the other surface side of the base material. A material layer is formed.

A sixth invention is the invention according to any one of the first to fifth inventions, wherein the first base material to which the carbide layer is fixed and the second base material to which the radioactive substance layer is fixed, The carbonized material layer and the radioactive material layer are present so as to face each other.
A seventh invention is characterized in that, in the invention according to any one of the first to sixth inventions, the sheet-like material is covered with a fabric having good air permeability.

The eighth invention is characterized in that the sheet-like material according to any one of the first to seventh inventions is formed in a band shape and a detachable engaging portion is provided.
The ninth invention is characterized in that, in the eighth invention, the width and length of the belt portion are set so that the belt-shaped portion can be wound around the sole and ankle portion of the foot.

Hereafter, each structure of the said 1st invention-9th invention is demonstrated.
In the first invention, examples of natural bast fibers include cocoon, mitsumata, and ganpi. These natural fiber materials are used for the Japanese paper described in the second invention. Natural bast fibers consist of phloem fibers, cortical fibers, etc. located outside the formation layer of the stem. Another plant with well-developed bast fibers is hemp and flax.
“Yarn made of natural bast fibers” includes the case of twisting hemp to make it like a rope. Hemp contains abundant bast fibers, and it is possible to produce the “woven carbon material layer” according to the present invention without using the “Japanese paper” described above.

The reason why charcoal's far-infrared radiation, deodorization, and antibacterial action are enhanced by using a woven carbonized material layer made by knitting yarn made of natural bast fibers and carbonizing the fabric spread in a plane is certain I don't know, but the possible reasons are as follows.
(1) By using natural bast fiber, which is a special fiber, as charcoal, far-infrared radiation, deodorization, and antibacterial action can be enhanced as compared with general Bincho charcoal and bamboo charcoal.
(2) By carbonizing the yarn made of natural bast fibers, the internal structure of the yarn-shaped charcoal becomes hollow, and the area in contact with air and gas can be increased in the hollow portion.
(3) Since the knitted yarn is charcoal, the entire charcoal structure is also a three-dimensional structure, and the contact area increases.

  The woven carbonized material of the woven carbonized material layer is used in a state of being attached to a base material such as a woven fabric or a non-woven fabric using a natural adhesive or the like so as not to be destroyed. A wide range of commercially available materials can be used as long as the woven or non-woven fabric to be attached has a certain level of air permeability.

  In relation to the second invention, in general, “Japanese paper”, in the narrowest sense, is made from fibers extracted from cocoons, mitsumata, ganpi, etc. and their waste paper as raw materials. In some cases, it refers to hand-made paper that incorporates a Japanese paste technique called “Nori”, which is mixed with a sticky “Neri” extracted from the roots of Toro-Aoi and barley.

In the present specification, the “Japanese paper” described in the second invention refers to a machine-made Japanese paper that has been produced from the latter half of the Meiji period, including the most narrowly-defined Japanese paper. And Japanese paper in a broad sense, that is, paper that is longer than Western paper and intertwined with fibers, and that is thick, thin, and tough. However, as the Japanese paper used as the woven carbon material layer, it is preferable to use the most narrowly-defined Japanese paper or machine-paste Japanese paper.
On the other hand, what is called western paper is mainly made of wood balp, and non-woody materials such as bamboo, which is the mainstream of Chinese paper, are used as raw materials, and paper fibers are shorter than bast fibers. It ’s not tenacious.

Of the three types of materials described above, the longest fiber is generally about 10 to 20 mm, and is easily entangled, and the fibers are connected to each other like a mesh and are the strongest. The fiber of the scab is shorter and shorter than 5mm, but it is translucent, glossy, sticky, smooth and smooth. Three-legged fiber is also short, like scabbard, but it has a characteristic that it can be obtained with a soft waist and elegant paper.
In the “carbonized material layer” described in the fifth to ninth inventions, a layer made of a carbonized material obtained from a natural plant mentioned in the first and second inventions and a fabric carbonized material layer mentioned in the third invention is also included. Used to include.

As the radioactive substance, for example, a substance contained in hot spring water can be suitably used. Examples of such a radioactive substance include radon (Rn: ²²² Rn), radium ( ²²⁶ Ra), and throne (Tn) which is a radioactive isotope of radon. : ²²⁰ Rn), actinone (An: ²¹⁹ Rn) and the like.
Examples of “the ore containing radioactive material” include, for example, mozanite. Also, if necessary, ores that emit a small amount of radiation erupted in hot springs can be used.

  Although it is harmful to the human body when exposed to high radiation, it is known that weak radiation has a positive effect on the human body, as hot springs have long been used for treatment. The present invention obtains effects such as blood circulation promotion, antibacterial action, and fatigue recovery by generating such weak radiation that has a beneficial effect on the human body from the radioactive substance layer. Although it has not been clarified scientifically what kind of effect the weak radiation has on the human body, one reason is as follows.

Since the absorption of radiation is absorbed by water that occupies 70% of the living body, it is necessary to investigate the chemical action after radiation has passed through moisture in the atmosphere or human body. It is known that when radiation passes through water (H ₂ O), H, —OH, e ^- _aq , H ₂ , H ₂ O ₂ , and H ₃ O ⁺ are generated. Among them, the active oxygen species such as —OH and H ₂ O ₂ function as so-called negative ions. Negative ions are known to have antibacterial and deodorizing effects. In addition, reactive oxygen species generated by radioactive substances and their decay products are expected to exert complex biochemical effects on the cells and tissues of the body and activate the functions of various organs. These actions are considered to be basically the same as those caused by radioactive hot spring water.
The effects are clinical medical effects such as sedation of autonomic nerves, adjustment of hormonal and metabolic abnormalities, and analgesia. In addition, weak α rays have the effect of calming nerve cells, and it is said that radioactive substances have the effect of relieving pain such as rheumatism, arthritis, and muscle pain. It has also been reported that weak radiation from radioactive substances increases the secretion of corticosteroids that have a significant effect on human immunity.

Examples of the activated carbon of the plant used in the third invention include Bincho charcoal and bamboo charcoal. The body wearing device according to the third invention is inferior in the generation of far-infrared rays compared to the first and second inventions, but due to the synergistic effect due to the radiation effect of the radioactive material layer, The blood circulation promoting action and the like can be increased as compared with the constructed body wearing device.
As described in the fourth invention, the form in which the radioactive substance layer is arranged in a planar shape is not particularly limited as long as the radioactive substance is arranged almost uniformly per unit area. For example, the radioactive material layer may be formed including not only a case where the entire surface is formed as a single sheet of paper or a sheet, but also a non-formed portion where the radioactive material layer is not formed, such as a lattice shape.

The body wearing device according to any one of the first to ninth inventions can be applied as various wearing devices such as a waist wearing device in addition to a belt-shaped wearing device and a shoulder wearing device.
In the fifth invention, as a method of “forming a carbide layer on the other surface side of the base material”, there is a method of fixing the carbide layer on the other surface side of the base material.
In particular, when the base material is made of a fabric such as a woven fabric or a non-woven fabric, the radioactive material layer is fixed to the fabric. Therefore, the fabric holding the woven carbon material layer is shared with the fabric holding the radioactive material layer. In addition, the thickness of the sheet-like material can be reduced, and the rate at which radiation, far-infrared rays, etc. reach the body can be increased.

  In the eighth aspect of the invention, for example, by attaching the band-shaped wearing tool to the joint portion of the human body so as to intersect the approximately 8 character shape, effects such as blood circulation promotion and pain relief are ensured while ensuring smooth movement of the joint portion. Can be obtained.

The effects of each invention will be described below.
If it is 1st invention and 2nd invention, it has the following peculiar effects.
(B) Negative ions are generated by the weak radiation emitted by the radioactive material layer. Therefore, it is possible to obtain both the preferable action of activated carbon such as generation of far infrared rays by the carbonized carbon material layer and the preferable action of generation of negative ions.
(B) Since the radioactive material layer is arranged in a planar shape, it can exert an effect of generating negative ions in a wide range and can supply radiation uniformly to the fabric carbonized material layer spreading in a planar shape, synergistically to the body A favorable effect can be amplified.

If it is 3rd invention, it has the following peculiar effects.
(C) Negative ions are generated by the weak radiation emitted by the radioactive material layer. Accordingly, it is possible to obtain both the preferable action of activated carbon such as generation of far infrared rays by the carbonized material layer and the preferable action of both negative ion generation.
(D) Since the radioactive material layer is arranged in a plane, it can exert an effect of generating negative ions in a wide range and can supply radiation uniformly to the carbonized material layer spreading in a plane, which is synergistically favorable for the body The effect can be amplified.

  If it is 4th invention, the said radioactive substance layer is provided with the formation part and the non-formation part planarly, The ratio of the area of the formation part which occupies for the whole area is 0.3-0.6, Since the air permeability is improved by the formation part, even if the radioactive material layer is formed, the air permeability in the direction passing through the sheet-like material can be improved, so the air reaching the carbonized material layer from the radioactive material layer side The amount of gas can be increased, and the effect of negative ion generation can be enjoyed without reducing the preferable effect of activated carbon.

According to the fifth aspect of the invention, since the radioactive material layer can be arranged on one side and the woven carbonized material layer can be arranged on the other side with only the base material having good air permeability interposed therebetween, a preferable mutual relationship between the radioactive material and the carbonized material is possible. The effect can be enhanced.
According to the sixth invention, the thickness of the sheet-like material can be reduced, and the radioactive substance layer and the carbonized material layer are disposed in close proximity to each other, so that a preferable interaction between the radioactive substance and the carbonized material can be enhanced. .

  If it is the seventh invention, by covering the sheet-like material with a fabric with good breathability, it is possible to prevent the carbonized material from being damaged by contacting an external object, and with a fabric with good breathability, The negative ion generation and the effect of the carbonized material can be enjoyed without reducing the contact with air, gas, or the like.

According to the eighth aspect of the invention, the sheet-like material is formed in a band shape and provided with a detachable engagement portion, so that it can be wound around a body arm, foot, ankle or the like, and is easy to wear.
If it is the ninth invention, since the width and length of the belt part are set so that the belt part intersects and winds the sole and the ankle part, the ankle and the arch part are mounted without hindering the movement of the ankle. can do.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a longitudinal sectional view of a body wearing tool showing a first embodiment of the present invention.
In addition, the following 1st Embodiment-3rd Embodiment has shown the sheet-like material 10 used for a body wearing tool.
A sheet-like material 10 shown in FIG. 1 is made by knitting a thread made of natural bast fibers, and carbonizing a fabric carbonized material layer 1 carbonized in a woven fabric spread in a planar shape, and a fabric fabric to which the fabric carbonized material layer 1 is fixed. And the like, a radioactive material layer 4 containing a radioactive material such as radon, and a second underlying material 3 such as a woven fabric to which the radioactive material layer 4 is fixed.

The natural bast fibers used in the woven carbon material layer 1 have a configuration in which bast fibers extracted from cocoons, cocoons, husks, and the like and hemp bast fibers are mixed. By using hemp bast fiber, the price per unit area can be reduced.
An adhesive is applied to the first base material 2 to such an extent that the air permeability is not impaired, and the woven carbon material layer 1 is attached, thereby integrating the woven carbon material layer 1 with the first base material 2 and activated carbon. Will be able to be used in the same way as ordinary fabrics.

  The radioactive material layer 4 is a natural ore of 0.1 μm to 1000 μm. Preferably, it is formed by applying a finely pulverized component pulverized to about 1 μm to 30 μm to the second base material 3 with a roller or the like. The basis weight may be set within a range in which the radioactive substance does not peel off from the base material such as a fabric even when used for a long period of time and can be used as a flexible sheet material. The amount of radiation and the amount of negative ions emitted by the radiation material described later are more important than the basis weight. If the amount of radioactive elements contained in the natural ore is large, the basis weight may be small, and if the amount of radioactive elements contained in the natural ore is small, a large amount is needed.

The first base material 2 and the second base material 3 can be made of synthetic fibers such as polyester, nylon, and polypropylene, as well as woven and non-woven fabrics such as natural fibers such as silk.
By attaching the first base material 2 to which the woven carbon material layer 1 is fixed and the second base material 3 to which the radioactive substance layer 4 is fixed with an adhesive, it can be used as a single sheet-like material 10. become.
The thickness of the sheet-like material 10 is a very thin structure of about 2 mm to 5 mm.

  The method of making one sheet-like material is not limited to the above method. For example, by applying an adhesive to both inner surfaces of the first base material 2 and the second base material 3 so as not to impair air permeability, and sandwiching the woven carbon material layer 1, the front and back surfaces are the first base material 2, Even if the method of forming the radioactive substance layer 4 on at least one surface of the front surface and the back surface of the sheet material 10 after manufacturing one sheet material 10 covered with the second base material 3 is adopted. good.

The method for forming the radioactive material layer 4 includes various methods such as applying with a roller or the like, stamping a coating liquid with a stamp member, spraying the radioactive material with a spray, and impregnating the base material with the radioactive material. Can be manufactured.
Further, in the configuration shown in FIG. 1, a protective material (for example, a fabric) made of fibers such as polyester, nylon, and polypropylene that covers the surface of the radioactive substance layer 4 so that the radioactive substance layer 4 is not directly exposed may be provided. .

(Second Embodiment)
FIG. 2 is a longitudinal sectional view of a sheet-like material showing a second embodiment of the present invention.
The second embodiment is different from the first embodiment in that the radioactive material layer 4 formed on the second base material 3 includes a forming portion 6 and a non-forming portion 7 in a plane, and the non-forming portion. The presence of 7 improves the air permeability in the direction passing through the sheet-like material 10.

3A to 3D are plan views of the radioactive material layer as viewed from above.
FIG. 3A shows a configuration in which the formation portions 6 and the non-formation portions 7 of the radioactive material layer 4 are formed in a square shape and arranged alternately, and FIG. 3B shows the formation portions 6 arranged at regular intervals. FIG. 3C shows a configuration in which the forming portion 6 is formed by a plurality of thick lines that intersect vertically and horizontally, and FIG. 3D shows a configuration in which the forming portion 6 is fixed. It is the structure formed with the specific pattern repeated with the rule of.

  3A to 3D, the ratio (s1 / S) of the area s1 of the forming portion 6 to the total area S of the sheet-like material is 0.1 to 0.9, preferably 0.3 to 0. .6, more preferably 0.4 to 0.6. If the area of the non-formed part 7 is s2, S = s1 + s2.

With the configuration of the second embodiment, the air permeability can be improved as compared with the case where the radioactive substance layer 4 is formed on the entire surface.
Thus, the radioactive substance layer 4 does not need to be formed on the entire surface of the base material, and the effect can be improved if it is arranged with a certain density. This is because the higher the air permeability, the easier the effects of the activated carbon of the woven carbon material layer 1, such as odor absorption, dehumidification and antibacterial properties. In addition to the shape shown in FIG. 3D, various specific patterns such as a honeycomb shape (octagon) can be adopted as the specific pattern repeated with a certain rule.

(Third embodiment)
FIG. 4 is a longitudinal sectional view of a sheet-like material showing a third embodiment of the present invention.
In the third embodiment, the first ground material 2 to which the fabric carbonized material layer 1 is fixed and the second ground material 3 to which the radioactive material layer 4 is fixed are combined with the fabric carbonized material layer 1 and the radioactive material layer 4. It is characterized in that it can be used as a single sheet-like material 10 by bonding using a method such as an adhesive or stitching so that the two face each other.
With this configuration, the thickness of the sheet-like material 10 can be reduced, and the radioactive substance layer 4 and the woven carbon material layer 1 can be arranged in direct proximity.

As shown in FIG. 5, the sheet-like material 10 described in the first to third embodiments is formed into a band shape, and its peripheral portion. Is stitched at the edge portion 14. In this embodiment, a pair of detachable engaging portions 8 are formed on at least both ends of the belt-shaped mounting tool 9. In this embodiment, a magic tape is employed as such a set of engaging portions 8.

  FIG. 5 shows an example in which one engaging portion 8 is formed at each end of the band-shaped wearing device 9, but one engaging portion 8 is attached to the front and back of both ends, and the band-shaped mounting is performed. It is good also as a structure which has four engaging parts in the tool 9 whole. Further, the engagement portion 8 may be formed on the entire surface of the belt-shaped mounting tool 9 by a method such as attaching a magic tape to the entire surface of the belt-shaped mounting tool 9.

  FIG. 6A is a perspective view showing a use state after the belt-shaped wearing device is wound around both ankles. Although the method of winding the belt-shaped wearing tool 9 around the foot can be considered as appropriate, for example, as shown in FIG. 6 (B), one footstep is placed on the belt-shaped wearing tool 9, and FIG. As shown in FIG. 6 (D), the pair of engaging portions are arranged so as to intersect the tip of the other end and the top of the foot. It can be installed by stopping with Velcro.

If it is this belt-shaped wearing tool 9, it is possible to attach the sheet-like material to the foot without interfering with the movement of the ankle and foot, improve blood circulation by far infrared rays, negative ion effect, numbness of the foot, In addition to relieving pain, anti-bacterial and deodorant effects can eliminate the unpleasant smell in shoes and socks.
The band-shaped wearing device 9 may feel that the effect is reduced when used every day, but at that time, it is exposed to direct sunlight for about 2 to 3 hours and dried to restore air permeability. It becomes possible to return the woven carbonized material to a state where the effect is exhibited.

(Fifth embodiment)
FIG. 7 is a perspective view for explaining a fifth embodiment according to the present invention.
The body wearing tool 11 in this embodiment is configured as a shoulder pad 12. The shoulder pad 12 shown in FIG. 7 is characterized in that the body wearing device described in the first to sixth inventions is formed in a short waistcoat shape covering at least the shoulder.
With this shoulder pad 12, even a person with a stiff shoulder can improve blood circulation by the far-infrared ray and negative ion effect, and can relieve stiff shoulders and pain. Moreover, since it is comprised by the very thin sheet-like material like 1st Embodiment-3rd Embodiment, for example, it should wear | wear easily by reducing the feeling of layering and an uncomfortable feeling on underwear, such as a shirt. Can do.

Specific examples will be described below.
(Example 1)
A sheet was produced by sandwiching both sides of a woven carbonized material obtained by knitting Japanese paper yarn and carbonizing a woven fabric spread in the shape of a sheet, with two polyester fibers. A radioactive material layer was formed on one surface of the sheet by printing using a radioactive material coating solution. The radioactive material layer was configured in the pattern of FIG. 3D, and the ratio of the formation part was set to 0.6.

The radioactive substance used was a mixture of 30 parts by weight of ore such as mozzanite crushed to 5 μm, 65 parts by weight of a ceramic material, and 5 parts by weight of a viscosity modifier. For the measurement of the amount of negative ions, an ion tester EB-13 manufactured by Eco Hollis Tech Co., Ltd. was used. The ion tester EB-13 converts the intensity of radiation into the amount of negative ions. The amount of negative ions in Example 1 was 1220.
The intensity of the radiation detected when used as a body wearing tool varies depending on the estimated time of wearing on the body, but is 0.05 μSV to 0.3 μSV, preferably 0.1 μSV to 0.2 μSV (microsheet Belt) grade. The amount of negative ions is 500 to 5000, preferably 500 to 2000, as measured by an ion tester EB-13.

As a measurement of the effect of the body wearing device, the five bandaged wearing devices shown in FIG. 5 and FIG. 6 were attached to one of the ankles (for example, the right ankle) for five testers who cooled their ankles for 30 minutes. A dummy that cannot be expected to have both far-infrared and radiation effects was attached to the other ankle (for example, the left ankle) for 30 minutes, and a body sensation survey was conducted to determine which ankle feels warmer. Also, in order to ensure that there is no difference between the senses of the left and right ankles, the left and right ankles of the five experimenters were cooled for 30 minutes, and then the experiment was performed by replacing the wearers on the left and right ankles. It was.
The dummy product does not contain ore containing radioactive material, and the coating liquid is composed only of ceramic material and the carbonized material layer is not used. Instead, it is replaced with a black woven fabric. I was not different.

  The level of the experimenter's sensation was tabulated as “feel very warm” as ◎, “feel warm” as ◯, “slightly warm” as △, “do not change” as −, and “feel cold” as x. Note that it is not clear to the five experimenters on which ankles the first and second examples, the first and second comparative examples, and the dummy product are attached. The results are shown in Table 1 below.

(Example 2)
The same radioactive material layer was formed except that the fabric carbonized material in Example 1 was replaced with a material obtained by crushing Bincho charcoal to about 20 μm and sandwiching it with polyester fibers. The amount of negative ions in Example 2 was 840.
(Comparative Example 1)
A sheet sandwiched with the carbonized fabric material of Example 1 was used as it was, and the coating liquid was printed only with the ceramic material to form a belt-shaped wearing tool. The negative ion amount of Comparative Example 1 was 120.

(Comparative Example 2)
A belt-shaped wearing tool was constructed by printing a coating solution with only a ceramic material on a material in which Bincho charcoal was pulverized to about 5 μm and layered between polyester fibers. The negative ion amount of Comparative Example 2 was 42.
(Dummy product)
As described above, the coating liquid is composed only of ceramic material without containing ore containing radioactive material, and the carbonized material layer is replaced with a black woven fabric, so that the appearance is almost the same as the band-shaped mounting device of the example product. Configured. The amount of negative ions of the dummy product was 5 (error range).

As can be seen from Table 1, Example 1 with a layer containing a radioactive material and a layer containing a fabric carbonized material, Example 2 with a layer containing a radioactive material and a layer containing a carbonized material, compared to other configurations, It turns out that blood circulation improves and a warm experience can be obtained.
In addition, in the case where particles containing radioactive material and particles containing carbonized material are mixed, only the warm feeling of the same degree as in Comparative Example 1 can be obtained, as in the first to third embodiments. It seems that there is a remarkable effect by arranging a layer containing a radioactive substance and a layer containing a carbonized material in layers.
Although it is not exactly known what causes this effect, the layer containing the radioactive material and the layer containing the fabric carbonized material are arranged in a plane, so that the layer containing the radioactive material and the fabric carbonized material are separated. It was confirmed that the synergistic action of the containing layer was larger than expected.
