[0012]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described. The tourmaline-containing undergarment 1 of the present invention uses the tourmaline-containing fiber Q as a part of the fiber (see FIG. 1).

That is, the tourmaline-containing fiber Q contains 0.05 to 2.0% by weight of tourmaline fine particles t having a particle diameter of 2.0 μm or less uniformly dispersed in the spinning solution of the fiber material (FIG. 3). reference). Since tourmaline has spontaneous permanent polarizability, it is more effective if it is made into fine particles. Therefore, in the present invention, particles having a particle size of 2.0 μm or less, preferably 0.5 μm or less, more preferably 0.3 μm or less are used, and particularly particles having a particle size of 0.2 μm or less and an average particle size of 0.15 μm or less are also used. Are more preferable because they emit more active electrons. The content of the particulate tourmaline is selected in the range of 0.05 to 2.0% by weight based on the fiber. If the content is less than 0.05% by weight, the amount of active electrons emitted is too small to exert the effect of the present invention sufficiently, and if it exceeds 2.0% by weight, the effect is improved relative to the amount. Not be done, but rather economically disadvantageous. From the standpoint of the balance between the amount of active electrons emitted and the economical efficiency, the fine particle tourmaline content is preferably 0.05 to 1.0% by weight based on the fiber. Examples of the tourmaline-containing fiber Q include regenerated fibers such as rayon and cupra, semi-synthetic fibers such as acetate, and synthetic fibers such as polyacrylic, polyvinyl alcohol, polyester, polyamide, and polyurethane.

In addition to tourmaline, other ceramics may be contained in the tourmaline fine particle-containing fiber Q of the present invention at a ratio of usually 10% by weight or less with respect to the fiber, if desired. Other ceramics preferably include, for example, far-infrared radiation materials such as cordierite mainly composed of alumina and silicic acid, β-spodumene, zirconia, zircon, magnesia, and aluminum titanate. Further, a transition metal compound such as manganese dioxide, iron oxide, chromium oxide, cobalt oxide, or copper oxide, or silicon nitride or silicon carbide may be contained.

Further, as the tourmaline-containing fiber Q, in addition to the tourmaline fine particles t, a fiber to which an antibacterial agent and a deodorant are added is used. These fibers are prepared by adding tourmaline fine particles t to a spinning dope and, if necessary, diluting with water to prepare a spinning dope having an appropriate concentration and viscosity. To this stock solution, an antibacterial agent and a deodorant may be added, and if necessary, a fungicide may be added. Then, the spinning solution is spun to obtain tourmaline-containing fibers Q. At this time, the following are examples of use of antibacterial agents and deodorants. -Antibacterial agent, deodorant agent-Antibacterial zeolite, synthetic zeolite (aluminosilicate of alkali or alkaline earth metal) part of the ion-exchangeable metal is antibacterial metal ions such as Ag, Cu, Zn Has been replaced. Silicone quaternary ammonium salt type, diphenyl ether type, triclosan type, trichlorocarbamide type, alkylpyridinium salt type cation type, chitin / chitosan type.

As the fabric composition of the undergarment 1 of the present invention, for example, 31% nylon is used for the outer material 3, 27% tourmaline-containing fiber Q is used for the inner material 2, 27% is polynosic cotton, and 15% is FTY (polyurethane / nylon). To do. In this way, the content ratio of the tourmaline-containing fiber Q is 20 to 40% of the whole dough.

The tourmaline used in the present invention is represented by a composition formula: MX ₃ B ₃ Al ₃ (Al SI ₂ O ₉ ) ₃ (O, OH, F) ₄ M = Na, Ca X = Al, Fe, Li, Mg , Mn.

Pure tourmaline is used as a gem, and it is now possible to artificially synthesize crystals. In the present invention, the tourmaline includes the artificial tourmaline. This tourmaline is a substance with permanent spontaneous electric polarization, and does not change the polarization vector due to the effect of an external electric field. In addition, tourmaline has the strongest permanent polarization property among minerals, and the amount of far-infrared radiation is also recognized. In addition, a piezoelectric effect in which the ion crystal causes dielectric polarization in response to a stress caused by an external force, and a pyroelectric effect in which electric charges appear on the surface when a part of the crystal is heated are observed.

Further, it has already been confirmed that active electrons are emitted from the fine particles of tourmaline contained in the fiber. -Example of activity test of tourmaline-containing fiber-In Example A, 350 parts by weight of an aqueous solution of caustic soda having a concentration of 20% per 100 parts by weight of pulp were added, and the mixture was stirred at room temperature for 2 hours according to a conventional method. Is prepared. Next, 30 parts by weight of carbon disulfide is added to the alkali cellulose and stirred at room temperature for 3 hours to obtain a solution of sodium cellulose xanthogenate. Then, this was diluted with a caustic soda aqueous solution to prepare a spinning solution (8.7% by weight of cellulose, 6.0% by weight of total alkali content, 2.4% by weight of total sulfur content), and the particle size obtained by the water granulation method was 0.2 μm. The following, and the tormaline fine particles having an average particle diameter of 0.15 μm were uniformly mixed with the fiber at a ratio of 0.05, 0.1, 0.2, 0.3, 0.5, 1.0, 2.0, 3.0, 5.0, and 7.0% by weight, respectively. .

The spinning dope containing tourmaline fine particles thus obtained was used with a spinneret having a pore diameter of 0.08 mm and a pore number of 50, and at a spinning speed of 60 m / min, 120 g / l sulfuric acid and 280 g / sodium sulfate were used. After being spun in a spinning bath containing 1 g of zinc sulfate and 15 g / l of zinc sulfate at a temperature of 50 ° C., it was drawn by an ordinary two-bath tension spinning method to obtain 10 kinds of samples of rayon fibers containing fine particles of tourmaline having a fineness of 15 d.

Using the tourmaline fine particle-containing rayon fiber obtained in Example A, active electrons were generated as described below, and the change in electric conductivity of water was measured.

The electrical conductivity was measured by indirectly measuring the active electrons of each sample by contacting air passing through the fiber with water and measuring the change in electrical conductivity of water. That is, FIG. 4 is a schematic diagram of an experimental apparatus for investigating the generation state of active electrons, in which each sample is mounted on the sample mounting unit 13 provided inside the sample activator 12 in the sample activating apparatus. From the blower pump 11, clean air subjected to treatment such as decarbonization is introduced into the sample activator 12 at a rate of 100 ml / min. At this time, the sample in the sample mounting section 13 is kept at 35 ° C. by a heating element such as ceramics provided in the sample activator 12. For this temperature control, the sample activator 12 is equipped with a thermometer 15 and a temperature sensor 16.

The air that has passed through the sample mounting portion 13 has a surface of distilled water 20 (which is kept at 21 ° C. by the constant temperature bath 18 and has an electric conductivity of 1.7 μS / cm 2 at 21 ° C.) stored in the beaker 19. Sprayed on. A platinum rod 21 was inserted into the distilled water 20, and the change in the electric conductivity was measured by an electric conductivity meter 22 (Precision LCR meter 4285A, manufactured by Hewlett-Packard Company). Reference numeral 17 denotes a power supply. The relationship between the electrical conductivity and the tourmaline content 3 hours after the start of the measurement is shown as a graph curve A in FIG.

In Example B, 10 kinds of samples were obtained in the same manner as in Example A by using tourmaline fine particles having a particle diameter of 1.0 μm or less and an average particle diameter of 0.8 μm.

The relationship between the electrical conductivity and the tourmaline content after 3 hours from the start of measurement is shown as a graph curve B in FIG.

As can be seen from FIG. 5, the electrical conductivity (curve B) of the tourmaline fine particle-containing rayon fiber having a particle size of 1.0 μm or less is a value of 2.08 to 2.17 μS / cm, which is a comparative sample containing no tourmaline. The value is higher than that of 1.84 μS / cm, indicating that a large amount of active electrons are emitted, but there is almost no change even when the content is 0.05 to 2.0% by weight.

On the other hand, the electrical conductivity (curve A) of the tourmaline fine particle-containing rayon fiber having a particle diameter of 0.2 μm or less (curve A) increases from the content of 2.0% by weight to the electrical conductivity of 0.2% and 0.2% by weight. It reaches a peak at 0.3% by weight, and decreases when the content is further reduced. That is, as compared with Example B, the electric conductivity shows a remarkably high value. In particular, it shows that an extremely large amount of active electrons are emitted in the range of 0.05 to 1.0% by weight with respect to the fiber. .

As shown in Japanese Patent Application No. 8-47463 and Japanese Patent Application No. 8-272486 filed by the present inventors, the skin temperature by thermography shows a correlation with electrical conductivity. , It was found that the skin temperature by thermography rises in conjunction with the increase in electrical conductivity due to the emission of active electrons.

The tourmaline-containing fiber Q used in the present invention is used by spirally wrapping around the waste yarn R (see FIG. 2). That is, after the tourmaline-containing fiber Q is entangled in a spiral shape, the waste thread R is removed to form a spiral thread S 1 having a hollow portion. When the lining is formed with such a spiral thread S, the heat insulating effect of the contact surface is enhanced, and the air permeability is improved to prevent stuffiness during use.

At this time, as the waste yarn R, a water-soluble yarn is used. That is, in the method of forming the spiral yarn S, a tourmaline-containing fiber Q (for example, rayon fiber is used) is spirally wound around a water-soluble yarn (for example, Nichibi Co., Ltd., trade name Solbron) (Fig. 2 ( B)). Next, after forming the dough in this state, the waste yarn R is melted (for example, it is melted with hot water of 60 degrees), and the waste yarn R is removed from the dough (see FIG. 2B). As a result, an empty cloth is formed by spirally winding the rayon fiber containing tourmaline.

27% of fiber Q having a hollow material formed by spirally winding the rayon fiber containing tourmaline as described above, 27% of polynosic cotton, 15% of FTY (polyurethane / nylon), 31% of nylon Figure 1 shows the same fiber composition as underwear except that rayon fibers containing no tourmaline were used for comparison with the underwear b of the present invention, which is a long-sleeved shirt using fibers using A long-sleeved shirt for comparison underwear (not shown) was made, and each of them was worn by a healthy person (32-year-old male), undressed after 10 minutes, and immediately measured the body surface temperature with a thermometer. However, in comparative underwear b, only a part of the back of the head has a slight red color, and most of the other part is a light blue color. Minutes also become red and spread over a wide area, and the temperature rises from 0.6 ℃ to 1.8 ℃, depending on the site. It is clear that this gives a good activating effect to living cells and promotes blood circulation.

Further, FIG. 6 shows a MV (microvibration) pattern test, and FIG. 6A shows MV test values immediately after wearing the comparative underwear b for 8 minutes. ) Is the MV test value immediately after wearing the underwear b of the present invention for 8 minutes. As shown in FIG. 6A, the amplitude in the β-wave band is large and the sympathetic nerve is dominant, but immediately after wearing the undergarment of the present invention in FIG. 6B for 8 minutes, the amplitude in the β-wave band decreases and the α-wave band decreases. It shows a state of becoming a band-dominant state, which indicates that feelings are relaxing and hypnotic effects are also exerting.
