By the way, health products that emit negative ions become more expensive because they contain grains or powder that emit negative ions. However, health products are often used while being exposed to ultraviolet rays, and there is a risk that they may deteriorate due to the ultraviolet rays and cannot be used for a long period of time.

The present invention has been made in view of the above circumstances, and an object of the present invention is to realize a health product that emits negative ions and is less susceptible to deterioration due to ultraviolet rays.

In order to solve the above-mentioned problems, the first invention is a health article used by humans or animals such as pets, comprising at least a part of the article and containing particles or powder that emit negative ions. An article comprising an article constituent material contained or attached as an ion-releasing material, and a fine particle coating composed of a large number of fine particles having photocatalytic activity and self-bonded to the surface of the article constituent material. It is a health product.

In a second invention, in the first invention, the article constituent material is a resin that is a main component and an ion-releasing material is blended therein.

In a third invention, in the second invention, the content of the ion-releasing material is 8% by weight or more and 15% by weight or less with respect to the total weight of the article constituent materials.

A fourth invention is the second invention, wherein the content of the ion-releasing material with respect to the total weight of the article constituent material is 10% by weight or more, and the main component resin of the article constituent material is a transparent silicone resin and a black color. Silicone resin is also used.

In a fifth invention based on the first invention, the article constituent material is made of fabric to which an ion-releasing material is attached.

A sixth invention is a health article used by humans or animals such as pets, which constitutes at least a part of the article and contains particles or powder that emit negative ions with respect to a resin that is the main component. The article comprises an article constituent material blended as an ion-releasing material and a fine particle coating composed of a large number of fine particles having photocatalytic activity that are self-bonded to the surface of the article constituent material. The content of the ion-releasing material relative to the weight is 8% by weight or more and 15% by weight or less.

In the present invention, a fine particle coating having photocatalytic activity is applied to the surface of an article component that releases an ion-releasing material. Therefore, ultraviolet rays are absorbed by the particulate coating, reducing the amount of ultraviolet rays that reach the article components. Therefore, it is possible to realize health products that are not easily deteriorated by ultraviolet rays.

Embodiments of the present invention relate to health articles and the like that are worn, worn, held in the hands, worn on the feet, or carried around by humans or animals such as pets. Health goods include, for example, accessories (necklaces, bracelets, pet accessories (collars, etc.), etc.), clothes, hats, personal items (umbrellas, bags, portable toiletry cases, etc.), and bedding (for humans or pets). ).

Embodiments of the present invention will be described in detail below with reference to the drawings. Note that the following embodiments are examples of the present invention, and are not intended to limit the scope of the present invention, its applications, or its uses.

<First embodiment>
The health article according to this embodiment is a necklace 10 that a person wears around their neck, as shown in FIG. As shown in FIG. 2, the necklace 10 includes a string-like necklace body 11 and a fine particle coating 12 applied to the surface of the necklace body 11. A pendant top 13 is attached to the necklace body 11 as a decoration. Further, both ends of the necklace main body 11 are provided with fasteners (not shown) that connect the both ends. Note that the necklace main body 11 corresponds to an article constituent material that constitutes at least a part of a health article.

The necklace body 11 is a stretchable string-like body whose main component is resin such as silicone resin. The necklace main body 11 contains powder (or grains) that emits negative ions as an ion-releasing material. Specifically, the necklace main body 11 is made of silicone resin mixed with an ion-releasing material. As a result, pollen and fine particulate matter (PM2.5) in the surrounding area become negatively charged and become adsorbed to the body surface or become heavy and fall, making it difficult for them to be absorbed through the nostrils. As the raw material for the ion-releasing material, materials that have an ionizing effect by radiation of ions and far infrared rays (for example, ores such as tourmaline, ceramics, etc.) can be used.

Here, the necklace 10 is used at a position close to the face. Therefore, negative ions can be expected to have the effect of alleviating hay fever. However, if the content of the ion-releasing material is low, the measured value of negative ions will be low, and a sufficient effect on hay fever cannot be expected. Therefore, the content of the ion-releasing material is set to 8% by weight or more based on the total weight of the necklace main body 11 so that a sufficient effect on hay fever can be expected. Note that this content is preferably 10% by weight or more.

On the other hand, it has been found that when the content of the ion-releasing material exceeds 15% by weight, the elasticity of the necklace main body 11 decreases, and there is a possibility that the strength of the necklace main body 11 may be insufficient against a tensile load. It was also found that when this content exceeds 15% by weight, the measured value of negative ions does not increase significantly. Therefore, in this embodiment, the content of the ion-releasing material with respect to the total weight of the necklace main body 11 is set to 15% by weight or less. In addition, in order to obtain sufficient strength against tensile load, this content is preferably 12% by weight or less.

The fine particle coating 12 is composed of fine particles having photocatalytic activity. As the fine particles, for example, titanium-based fine particles such as titanium dioxide or titanium hydroxide can be used. In this case, titanium dioxide or titanium hydroxide alone may be used, or titanium dioxide and titanium hydroxide may be used in combination.

The titanium-based fine particles have a maximum particle size of 100 nm or less. Usually, photocatalytic coatings using titanium dioxide or the like use a binder containing particles of titanium dioxide or the like. In this case, many particles are buried in the binder and a sufficient photocatalytic effect is not exhibited. On the other hand, in this embodiment, since the titanium-based fine particles are ultrafine particles, the titanium-based fine particles have self-bonding properties due to intermolecular forces, and can self-bond to the surface of the necklace main body 11 without using a binder. adhere to. The fine particle coating 12 does not use a binder, and as shown in FIG. 2, most of the titanium-based fine particles are exposed, so it exhibits an excellent photocatalytic effect.

[Necklace manufacturing method]
The method for manufacturing the necklace 10 includes a main body manufacturing step of manufacturing the necklace main body 11 and a coating step of applying the fine particle coating 12 to the necklace main body 11 in this order.

In the main body manufacturing step, a blending step of blending an ion-releasing material into a resin such as a silicone resin, and a molding step of molding the resin blended with the ion-releasing material into a string shape are performed in this order.

Here, when attempting to manufacture the black necklace body 11 and blending black toner in the blending process, if the content of the ion-releasing material exceeds 10% by weight, the necklace body 11 will be damaged due to the influence of the ion-releasing material. , it turned gray instead of black. That is, when increasing the content of the ion-releasing material in order to enhance the pollen reduction effect, a black necklace body 11 could not be obtained if a black toner was blended in the blending step. Therefore, in this embodiment, the black necklace main body 11 is manufactured by using a transparent silicone resin and a black silicone resin together without using toner for coloring. Note that if the blending ratio of black silicone resin is increased, there is a risk that color transfer to the user will occur. Therefore, the amount of black silicone resin is set at 5% by weight or more and 15% by weight or less (for example, 10% by weight) with respect to the total weight of the transparent silicone resin and the black silicone resin.

In the coating step, a pulverization step of making titanium dioxide into fine particles, a dispersion step of dispersing fine particles of titanium dioxide in an aqueous solution to obtain a water-soluble coating agent, and a step of spraying the water-soluble coating agent onto the necklace body 11 to form a necklace body. The spraying step of coating No. 11 is performed in this order.

In the atomization step, titanium tetrachloride as a raw material is reacted with an aqueous solution of a water-soluble alcohol at room temperature, for example, to obtain fine particles of titanium dioxide having a maximum particle size of 100 nm or less. In this reaction, titanium tetrachloride reacts with water to produce fine particles of titanium dioxide. At that time, the water-soluble alcohol becomes an aqueous solution, which prevents the reaction between titanium tetrachloride and water molecules from occurring rapidly and continuously, so the reaction products aggregate together and grow larger. This can be avoided. Note that in the atomization step, fine particles of titanium hydroxide may be generated.

Regarding the composition of the aqueous solution of water-soluble alcohols, it is desirable that the proportion of water-soluble alcohols be in the range of 50% by volume or more and 80% by volume or less. When the proportion of water-soluble alcohols is less than 50% by volume, the reaction between titanium tetrachloride and water proceeds rapidly, and the amount of titanium dioxide, which is a reaction product, becomes excessive in the aqueous solution, causing fine particles to aggregate and aggregate with each other. This causes the particle size to increase. On the other hand, if the proportion of water-soluble alcohol exceeds 80% by volume, there will be a shortage of water, resulting in variations in particle size, making it impossible to uniformly disperse the fine particles.

Further, the amount of titanium tetrachloride added is preferably 10% by volume or less based on the total volume of the aqueous solution of water-soluble alcohols. This is because if the amount of titanium tetrachloride added exceeds 10% by volume, the amount of titanium dioxide, which is a reaction product, becomes excessive in the aqueous solution, causing fine particles to associate and aggregate with each other, resulting in an increase in particle size.

In the spraying step, for example, the water-soluble coating agent obtained in the dispersion step is sprayed onto the necklace main body 11 in a suspended state. The water-soluble coating agent is sprayed onto the necklace main body 11 from a plurality of directions. Then, after the surface of the necklace main body 11 is dried after the spraying process, the pendant top 13 and the fastener are attached, thereby completing the necklace 10 according to the present embodiment.

[Effects of this embodiment, etc.]
In this embodiment, a fine particle coating 12 having photocatalytic activity is applied to the surface of a necklace main body 11 containing an ion-releasing material. Here, negative ions are said to have the effect of sterilizing the surrounding area by utilizing the oxidizing power of the generated radicals. On the other hand, it is said that photocatalysts have a sterilization effect by utilizing oxidizing power. Therefore, in terms of the sterilization effect, there is no need to combine a photocatalyst with the ion-releasing material. In this embodiment, we deliberately focus on ultraviolet absorption as an effect of the photocatalyst, and employ the above-mentioned fine particle coating 12. According to this embodiment, the amount of ultraviolet rays that reach the necklace main body 11 is reduced, and it is possible to realize a necklace 10 that is not easily deteriorated by ultraviolet rays.

<Second embodiment>
This embodiment is a health article 10 using a fabric 11 to which an ion-releasing material is attached (referred to as "ion-releasing fabric"). The health article 10 may be clothing, a hat, bedding, or the like using the ion-emitting fabric 11. As shown in FIG. 2, the health article 10 includes an ion-releasing fabric 11 that is a component of the article, and a fine particle coating 12 applied to the surface of the ion-releasing fabric 11. Note that clothes and the like may be for pets instead of for humans.

According to this embodiment, as in the first embodiment, the ion-emitting fabric 11 is less likely to deteriorate due to the fine particle coating 12 having photocatalytic activity. Furthermore, according to the present embodiment, ultraviolet rays passing through the ion-emitting fabric 11 are reduced by the fine particle coating 12, so that sunburn on the wearer of the clothes or hat can be suppressed.

Note that the health article 10 may be an umbrella in which an ion-emitting fabric is used as the umbrella fabric 11 attached to the bone member. According to this umbrella, it is possible to prevent the user of the umbrella from getting sunburned.

A pollen removal performance test was conducted on the necklace main body 11, which is made of a silicone resin mixed with an ion-releasing material. The content of the ion-releasing material with respect to the total weight of the necklace main body 11 was 10% by weight.

The measurement was carried out using pollen (cedar pollen or cypress pollen) at a concentration of 7,500 particles/cc for each case where the necklace body 11 was placed in a 60 liter (50 cm x 40 cm x 30 cm) box and when the necklace body 11 was not placed. ) and measured the pollen concentration over time. As a device for measuring this concentration, a DC110 Pro B model manufactured by DYDOS CORPORATION was used. Table 1 shows changes in pollen concentration with the initial concentration being 100%.

According to the pollen removal performance test, it was found that this example was effective in reducing the concentration of both cedar pollen and cypress pollen.
