Definitions
- the present invention relates to a sheet to which various desired functions such as emission of a relatively low level of radiation and photocatalysis are added (as described herein, a sheet to which a desired function is added as described above).
- the term “functional sheet” is referred to as “functional sheet”, and the other term “functionality ⁇ ” refers to the “object” indicated by the word of the second element inserted in the “ ⁇ ” part. ) Is used for the purpose of obtaining, for example, health promotion effects, relaxation effects, antibacterial effects, deodorization effects, etc. obtained by irradiation of relatively low levels of radiation or generation of negative ions.
- far-infrared ceramics generate far-infrared rays and, for example, irradiate the far-infrared rays to the human body to add functions such as improvement of stiff shoulders and chills due to promotion of blood circulation.
- Carrying force Far-red ceramics generate a small amount of far-infrared rays when no thermal energy is applied, and their effects are limited. Therefore, even if far infrared ceramics are used alone, no significant effect can be expected.
- tourmaline generates negative ions, also called tourmaline, and is used to generate negative ions which are added or supported for the purpose of adding functions such as a relaxation effect and improvement of biological functions. Need to be vibrated.
- a functional fiber that emits radiation by kneading a powder of an ore (for example, monazite) containing a radioactive rare earth element such as thorium (Th) into a fiber material of a synthetic fiber product. Products have also been developed, and such functional fiber products can emit radiation without burning off the energy of external forces.
- an ore for example, monazite
- Th thorium
- photocatalytic substances such as titanium oxide are known as substances having a function of generating negative ions and decomposing harmful substances in the air.
- Functional fiber products have also been developed in which a powder of a substance is carried on a fiber product to provide functions such as generating negative ions and decomposing and removing harmful substances.
- a general photocatalytic substance is called anatase type, and when irradiated with light, reacts with ultraviolet components of the substance to generate negative ions and perform photocatalytic functions such as decomposition of harmful substances. It does not react in the visible light region, and thus does not exhibit the above-mentioned effects indoors or in a dark place. As a result, the uses for which it is used are limited.
- a photocatalytic substance that exhibits a photocatalytic function in response to not only ultraviolet rays but also electromagnetic waves having a longer wavelength light such as ⁇ -rays, X-rays, ultraviolet rays, visible rays, infrared rays, and radio waves.
- electromagnetic waves having a longer wavelength light such as ⁇ -rays, X-rays, ultraviolet rays, visible rays, infrared rays, and radio waves.
- a metal film having a gradient structure in which oxygen bound from the surface to the inside gradually decreases referred to as “oxygen-deficient gradient structure” in this specification
- a photocatalytic substance formed on the surface of the product to be treated has also been developed (Patent Document 1).
- the prior art document information of the present invention includes the following.
- Patent Document 1 Japanese Patent Laid-Open No. 2002-85981
- Non-patent document 1 “Development of products with negative ion fibers” published in Senken Shimbun (June 12, 2001)
- external heat or vibration energy may be applied to the generation of far infrared rays and the generation of negative ions, such as bincho charcoal, far-red ceramics, and tourmaline.
- negative ions such as bincho charcoal, far-red ceramics, and tourmaline.
- functional fiber products that carry the necessary powder If, for example, clothing, such as underwear, is manufactured and worn for the purpose of promoting blood circulation in the body, these functional fiber products are used in a state where they are shielded from the outside by outerwear worn on them. Therefore, only limited energy such as body temperature can be used, and the effect cannot be fully exerted.
- the photocatalytic substance in the photocatalytic substance provided with an oxide film having an oxygen-deficient gradient structure shown in Patent Document 1 described above, the photocatalytic substance exhibits a photocatalytic function in response to an electromagnetic wave having a wavelength longer than that of ultraviolet light. Even when used in a state where external forces are blocked by outerwear, etc., the photocatalytic reaction can be caused by irradiation with electromagnetic waves transmitted through the outerwear. In some cases, the reaction cannot be performed sufficiently.
- a metal powder to be an oxide film is coated on the surface of a product to be treated such as a ceramic ball by a blast method or the like. Since the above-mentioned oxidized film is formed on the surface of the article to be treated by spraying, the shape and size of the photocatalyst material to be produced are restricted by the shape and size of the article to be treated. In addition, it is difficult to form an oxide film on a minute object such as a powder, which is to be treated, and the resulting photocatalytic substance has a relatively large size.
- an object of the present invention is to solve the above-mentioned drawbacks in the prior art, and it is possible to exhibit a desired function with high efficiency to a powder carried without input of external energy.
- the purpose of the present invention is to provide a functional sheet that can be made and is not easily restricted by use conditions.
- the functional sheet 1 of the present invention has a photocatalytic function by oxidation.
- a photocatalyst powder 10 formed by oxidizing a metal powder that exerts a structure in which the bond with oxygen gradually decreases as it enters the surface force;
- a carrier 30 such as non-woven fabric or paper
- the photocatalyst powder 10 exhibits a photocatalytic function by oxidation, for example, titanium (Ti), tin (Sn), zinc (Zn), zirconium (Zr), and titanium.
- a powder of a metal such as tungsten (W) is injected with a compressed gas and collides with a collision target made of a metal or ceramic having a melting point equal to or higher than that of the metal powder, or a mixture thereof, thereby causing acidity. It is possible to use the one that has been made (claim 2).
- the carrier 30 has a laminated structure, and the photocatalyst powder 10 and the radioactive powder 20 are sandwiched between the layers (31, 32) of the carrier 30 in a mixed state, whereby this is sandwiched. It may be carried (see claim 3; FIG. 1), or
- the carrier 30 may have a laminated structure of three or more layers, and the photocatalyst powder 10 and the radioactive powder 20 may be separately sandwiched between the layers of the carrier 30 to support them. Item 4; see Figures 2 and 3).
- the particle diameter of the photocatalyst powder 10 and the radioactive powder 20 is preferably # 46 (420 m
- the particle diameter includes both the particle diameter of the photocatalyst powder and the particle diameter of the radioactive powder. Specific surface area) can be increased. In addition, if it is less than # 46, it is inappropriate because it causes pain when it comes into direct contact with the skin, and if it exceeds # 220, the texture of the nonwoven fabric leaks out.
- the radioactivity is adjusted so that the weight ratio of the thorium to the total weight of the obtained functional sheet 1 is 0.1 to 2.0 wt%.
- the amount of thorium is determined by the total weight of the "functional sheet" completed as described above [support ( Weight of nonwoven fabric) + weight of photocatalytic powder + weight of radioactive powder]. As will be described later, the concentration of the radioactive substance in the obtained functional sheet 1 can be suppressed to a solid level of 370 Bq / g or less, which is a legal regulation in Japan.
- the invention's effect is determined by the total weight of the "functional sheet" completed as described above [support ( Weight of nonwoven fabric) + weight of photocatalytic powder + weight of radioactive powder].
- the functional sheet 1 of the present invention has the following remarkable effects.
- the photocatalyst powder 10 described above also reacts to an electromagnetic wave having a wavelength longer than that of ultraviolet light to exhibit the function of a photocatalyst.
- a photocatalytic reaction occurs, and even when used in a use environment where the input of external energy is limited, a sufficient photocatalytic reaction can be caused, and this photocatalytic reaction can be performed.
- the desired effect could be obtained with high efficiency even when only a relatively small amount of the radioactive powder 20 was carried without risk of radiation damage.
- the metal powder injected together with the compressed gas is caused to collide with an object to be oxidized to oxidize the metal powder into the above-described oxygen-deficient gradient structure, thereby preventing electromagnetic waves having a wavelength longer than that of ultraviolet rays.
- the photocatalyst powder 10 which responded to the above was relatively easily obtained.
- the carrier 30 is formed in a laminated structure, and the photocatalyst powder 10 and the radioactive powder 20 are sandwiched between the layers of the carrier 30 in a mixed state or separately, so that the carrier 30
- the functional sheet 1 having a simple structure and extremely easily manufactured could be provided.
- the specific surface area of the photocatalyst powder 10 could be increased, and the photocatalytic reaction could be easily caused.
- the radiation dose can be reduced. Obstacle It could be out of the applicable range of the Hazard Control Law (concentration in solids is 370Bq / g or less).
