DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tourmaline nonwoven fabric having fine tourmaline particles fixed and supported on the fiber surface of the nonwoven fabric.

[0002]

2. Description of the Related Art Tourmaline (also called tourmaline) is a polar crystal,
Since it has useful functions such as a negative ion generating function, a far-infrared ray generating function, an electromagnetic wave absorbing function, an antibacterial function, and a deodorizing function, its various uses have recently been promoted. Above all, it is known that the effect of generating negative ions based on the electrostatic polarization of tourmaline increases as finer the powder. The fine particles of tourmaline can be said to be a mixture of minute permanent batteries.Therefore, for example, in order to effectively generate hydroxyl ions as negative ions by acting with moisture or water in the air, it is necessary to use water clusters. And (+)
Unless the (-) tourmaline counter electrode approaches, hydroxyl ions (negative ions), which are the result of weak electrolysis, are not efficiently generated. In addition, the relationship between the particle size of the tourmaline and the effect is as follows.
It has an electrostatic field of KV / mm, but if the particle size is large, the electrostatic field drops rapidly, and the tourmaline effect does not increase even if the medium is applied many times to a large particle size.

[0003] Since handling in the form of fine powder is difficult, it is used as a product mixed with other materials and having a porous and gas-liquid contact area. For example, in the application of water treatment, a porous ceramic plate or ceramic ball kneaded with clay and sintered at a temperature of 1050 ° C. or less, a macaroni-shaped porous ceramic material, and the like are often used. However, tourmaline, for example, at 950 ° C. or higher, loses the above-mentioned negative ion generating function, so that fired ceramics cannot expect an effect based on the function. Furthermore, in existing tourmaline ceramic balls, the tourmaline action is only at an electrostatic field at a distance of 50 μm from the surface. Therefore, in the tourmaline ceramic ball, if the (+) and (-) pairs of the tourmaline fine electrode do not clearly appear on the surface, there is no effect if the tourmaline submerges in the material,
The tourmaline hidden inside did not work. In addition, in the mixed product of tourmaline fine particles (powder) and binder,
Since the surface of the tourmaline fine particles is covered with the binder and the surface area in contact with the gas-liquid is reduced, the effects based on the various functions are reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The antibacterial effect of tourmaline by generating far-infrared rays and negative ions, the deodorant effect, the physiological effect on the human body, and the electromagnetic wave shielding effect are well known. Since the tourmaline fine particles are fixed and carried on the surface of each fiber of the nonwoven fabric, and a part of each particle is in contact with the fiber surface side, the non-fixed portion of the remaining tourmaline fine particles is in free contact with gas and liquid. The product has a large tourmaline surface area per unit volume. The tourmaline fine particles are obtained by pulverizing tourmaline crystals with a pulverizer and sieving, and preferably have a particle size of 0.5 μm to 3 μm.

[0007] Nonwoven fabrics are usually produced by arranging fibers in a web shape and bonding the fibers together with an adhesive. The fibers include rayon, acetate, nylon, and the like.
Plastic fibers such as polyester, cotton fibers, glass fibers, carbon fibers and the like are used alone or in combination (blended). As the adhesive, acrylic, EVA
(Ethylene-vinyl acetate copolymer), various synthetic resins such as vinyl chloride copolymer, nitrile rubber latex, urethane rubber latex, emulsion of synthetic rubber such as SBR (styrene-butadiene rubber), natural rubber latex and the like are used. In the production of the tourmaline nonwoven fabric of the present invention, After dipping or spraying the web in an adhesive solution, Remove excess adhesive by squeezing with a mangle or the like. After drying and heat treatment, By sprinkling or spraying the tourmaline fine particles on the one that has just finished, the tourmaline fine particles are applied to each fiber surface (the adhesive layer on the fiber surface), and only a part of each of the particles is applied to the fiber surface. Is fixed and carried in contact with the adhesive layer of As a result, as shown in FIG. 2 in an enlarged view of the nonwoven fabric carrying fine particles of tourmaline shown in FIG. 1 and a partially enlarged view including a partial cross-sectional view thereof, the adhesive layer 4 covering the fiber material 3 of the nonwoven fabric is formed. On the surface, the tourmaline fine particles 2 are fixed and supported with a part thereof bonded to the adhesive layer 4. As shown in FIGS. 1 and 2, the nonwoven fabric 1 has a uniform finish with little fraying and clogging, and the fine particles 2 of tourmaline are finely dispersed almost uniformly on the surface of the fiber material 3. The particles are secured by an adhesive layer 4 of fibers so that most of the particles are exposed.

[0008] The tourmaline nonwoven fabric of the present invention as described above is excellent in air permeability and water permeability, and since most of the fine particles of tourmaline are exposed, the tourmaline effect against gas-liquid contact is high. Demonstrated with efficiency. When the gas or liquid to be contacted is food or drink, a material harmless to the human body is selected and used as the bonding agent. Preferred examples of the use of the trimarin nonwoven fabric of the present invention include the following. (1) Filter for air purification (for example, in air conditioners, air purifiers, etc.). (2) Functional drinking water production medium (for producing drinking water with high negative ion or wave value). (3) For agriculture (for example, to increase negative ions in indoor air of a plant growing greenhouse). (4) For fisheries (for example, for aquaculture water reforming). (5) For electromagnetic wave shielding (for example, in CRT frames, anechoic chambers, etc.). (6) For indoor walls (for example, for the production of a healthy living room with a large amount of negative ions). (7) For lightweight quilted clothing components. (8) For health and medical equipment. (9) For producing modified water for producing a water / oil mixed emulsion.
