Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a powder for infrared weak energy radiation and a synthetic fiber mixed with the powder.

<Prior Art> The existence of ceramics as a “functional material” that emits infrared weak energy (also called far infrared rays) is known, but these emit infrared weak energy to cause some change in physical properties of a target object. There is still a lot of uncertainty about what kind of target object and what kind of change in physical properties is expected, although a common understanding is made as what causes it. Therefore, it has not been known what kind of component is suitable as the ceramic as the "functional material".

Generally, infrared weak energy is radiant heat like solar rays, and can directly heat the target object without heating the gas or liquid between them, and it penetrates into the target object like microwave oven using microwave, so surface temperature is unnecessary. The inside can be heated without increasing the temperature. Therefore, while being widely used as a so-called heater for stoves, stoves, kotatsu, etc., when the stone is heated like stone-baked potato, infrared weak energy emitted from the stone burns the inside of the potato to make it warm and familiar. Has been used since ancient times.

However, it has become known that the infrared weak energy has not only a function as a heater but also many advantages such as aging of foods, shelf life, improvement of taste, ionization of atmosphere, and the like. Although the mechanism is largely unknown, experiments by the present inventor have revealed that infrared weak energy is effective not only for industrial applications but also for food and consumer products.

Although the weak infrared energy tends to be used more and more in the future as described above, on the other hand, the effect cannot be expected so much unless the weak infrared energy is irradiated / emitted in the wavelength range suitable for the target object (substance). Are known. For this purpose, it is preferable to use ceramics as an "infrared weak energy radiator" which has a large wavelength range and can radiate a sufficient amount of infrared weak energy, and it is easy to use any component as a material for such ceramics. Development was desired.

Therefore, in view of such conventional demands, the present inventor has previously proposed a powder for far-infrared radiation, which has a large wavelength range and can radiate a sufficient amount of infrared weak energy (Japanese Patent Application No. Hei 1 (1999) -135242).
-328396 (see Japanese Patent Publication No. 5-45637)).

<Problems to be Solved by the Invention> Since the powder according to the above proposal is very useful, it is desired to develop another powder capable of radiating the same effective infrared weak energy as the above proposal. It was

<Means for Solving the Problems> The present invention was developed in response to the above-mentioned demand, and uses palladium in place of the previously proposed platinum. Specifically, the gist is that the powder for infrared weak energy radiation is formed by adding palladium as an additive of alumina and titanium. Titanium is an essential substance in the present invention, and when it is lacking, it has a large wavelength range and cannot radiate a sufficient amount of infrared weak energy.

<Operation> When the powder having the above composition is subjected to the secondary processing and the tertiary processing and applied to the target object, the energy ratio in the wavelength region is high (wavelength 4 μm or more), and the temperature is relatively low (up to 700 ° K) and Sufficient energy radiation is obtained in both the relatively high temperature range (700-1300 ° K). It is generally effective in the wavelength range of 3 to 12 μm and can be applied to many applications.

Further, when the powder is mixed in a synthetic fiber such as nylon in a dispersed state, infrared weak energy is emitted from the entire fiber. Therefore, stockings, underwear, etc. using this synthetic fiber are very warm and effective for chilliness and joint pain due to cold.

<Examples> As described above, the present invention provides a powder for emitting infrared weak energy, which powder is obtained by adding palladium as an additive to alumina and titanium. As "alumina", 30 to 45% of sintered alumina having a purity of 99.9% or more in a powder state having a particle size of 1 µ or less is added. "Titanium" is also powdered to the same level 55 ~
Add 70%. And the particle size of "palladium" is 7-40Å
It is used in the form of a colloid having a fine diameter, and is added in the expectation of so-called colloid activation when oxygen and hydrogen are adsorbed. Furthermore, by adding silicon nitride having a grain size of 0.34 μm or less in addition to the above components, a more suitable powder can be obtained. This silicon nitride improves the function of hydrogen, and restricts the movement direction of hydrogen ions in a certain direction. The addition amount of such silicon nitride is preferably about 2.3%. This powder can be used as it is, but it is also possible to use it by forming it into a polymer pellet or a sheet.

Here, when the infrared weak energy radiation amount of the 0.3 mm thick sheet was examined, the energy ratio in the wavelength region was high (wavelength 4 μm or more) and the temperature range was relatively low (up to 700 ° K).
[See Fig. 1], relatively high temperature range (700-1300 ° K)
It has been found that a sufficient amount of energy radiation can be obtained in both [see FIG. 2].

Further, the powder according to this example is mixed by a known means with synthetic fibers such as nylon, vinylon, ester, acrylic and urethane in a dispersed state, and various products as described below can be produced by using the fibers.

Clothes such as pantyhose and underwear The weak infrared energy radiated from the fibers that make up pantyhose and underwear penetrates into the body, promoting blood circulation and providing an excellent heating effect. 100 fibers containing the powder of the present invention
%, It is not necessary to perform spinning, and it is also effective to use a blended fiber with ordinary fibers. In addition, it is effective for symptoms such as coldness and arthralgia just by using the fiber mixed with the powder only in the knees and elbows. As described above, the reason why the fibers are healthy is that the weak infrared energy emitted from the fibers is absorbed deep under the skin of the human body and activates the movement of water molecules in the cells. That is, the activated water molecule activates the cells of the human body tissue, and activates metabolism such as discharging the waste that has stagnated inside the cells to the outside of the body. Then, the flow of blood and body fluid improves, oxygen and nutrients spread throughout the body, and the cells become healthy.

Bedding such as blankets and duvets When a bedding such as a futon, a blanket, and a pillow is made of the fiber of the present invention, not only there is a heat retention effect and blood circulation promotion like the above clothing, but also deodorizing effect by infrared weak energy emitted by itself. Or, there is also an effect such as constantly obtaining a fluffy dry state, and using three types of futons, a duvet, a woolen duvet, and the temperature distribution after 30 minutes of sleep, Since the feathers and the wool show excellent heat retaining ability, the futon made of the fiber of the present invention has obtained good results. In particular,
As a result of investigating the human body temperature distribution map of Thermo Eye Vision, it was confirmed that the body temperature of the case where the futon according to the present invention was used was higher than that of the case where the duvet of the present invention was used. Also, although the amount of radiation is not so large, the infrared weak energy is also radiated from the human body, so the infrared weak energy from the futon and the infrared weak energy from the human body radiate and absorb each other, and the infrared weak energy is amplified. Therefore, the effect of the infrared weak energy is further enhanced.

Packaging material made of fibers If a non-woven fabric is made of fibers mixed with the powder according to the present invention, and this non-woven fabric is used for packaging fresh food,
Excellent freshness fiber effect. In other words, since meat and fish are made up of 70% or more of water, the more the molecular movement of water is activated, the more fresh the cells of meat and fish are kept. The infrared weak energy emitted from the fiber gives resonance and resonance motion to water molecules in the tissues of meat and fish, and as a result, the hydrogen ion and hydroxide ion molecular groups (clusters) of water molecules become smaller while strengthening their bonds. By promoting enzyme activation in cell tissues and strongly suppressing free water on the surface of meat and fish, it is possible to suppress aerobic fungal reproduction and metometosis (browning phenomenon).

In order to prove the above, the size of each water molecule group of the water content of fish using the non-woven fabric according to the present invention and the water content of fish using the conventional non-woven fabric is shown in FIG. 3 by NMR spectroscopy (nuclear magnetic resonance). The results of comparative experiments by spectroscopy are shown below. The results show that the size A of the water molecule group of water to which the infrared weak energy is applied according to the present invention is smaller than the size B of the water molecule group of water to which the infrared weak energy is not applied. That is, the water molecular groups of water are artificially destroyed by the infrared weak energy and become smaller. In other words, the fact that the water molecule population of water becomes small in other words means that the activated water molecules again trap the dissolved oxygen in the molecule population, which causes a structural change of water and causes bacteria such as bacteria. Fungi result in the suppression of their reproduction.

<Effects of the Invention> As described above, the powder for infrared weak energy radiation according to the present invention is easy to use as a material for forming an infrared weak energy radiator, and can be used in pellet form, sheet form, or powder form as it is. Since it can be formed in any shape according to the shape, structure, material, etc. of the object and is easy to use, it has a large wavelength range as infrared weak energy and a sufficient energy radiation amount can be obtained. There is an advantage that it can be expanded.

Further, the synthetic fibers mixed with the powder in a dispersed state,
It is suitable for clothing, bedding, etc., and it is possible to obtain both a heat effect for the body and a health promoting effect by the weak infrared energy emitted from the entire fiber. In addition, when a packaging material is made from this synthetic fiber, it has excellent freshness fiber effect and antibacterial effect on meat and fish.
