Prior art of compositions having both negative ion health maintenance action and antibacterial and deodorant properties, and photocatalytic functional materials capable of obtaining deodorant action and antibacterial action by sunlight are available in patent applications or on the market. Typical examples of these are as follows.
Patent No. 3035279 Resin composition that emits far infrared rays at the same time as emitting a negative ion containing a polymer compound that is not easily charged with static electricity, a rare element, and at least one of tourmaline or far infrared radiation ceramics . [Patent Document 1] Japanese Unexamined Patent Publication No. 2000-110062 (1) For a stretch woven or knitted fabric, a polymer base material that is not easily charged with static electricity and a single powder of mineral containing rare earth, or a mineral containing rare earth and tourmaline or far-infrared ceramic powder A multifunctional stretch woven or knitted fabric obtained by subjecting a resin composition obtained by mixing a mixed powder containing any one of the bodies to a surface treatment or a stripe or mesh coating or printing treatment .

(3) Elastic supporters, socks and underwear woven and knitted with a knitting and knitting machine, at least on the entire surface or part of the front and back, a polymer substrate that is not easily charged with static electricity, minerals containing rare earths, tourmaline, or far-infrared rays A multi-function characterized in that a resin composition obtained by mixing a mixture containing any one of ceramics is printed in the form of a dot, stripe, mesh, or pattern, or dipped. Sex supporters, socks and underwear. [Patent Document 1] Japanese Patent Application Laid-Open No. 10-195564 An inorganic fine particle-adhered fabric in which inorganic fine particles that emit energy that generates negative ions in the air are adhered to the surface of fibers constituting the fabric. JP, 10-212456, A Coating composition for textile materials characterized by including a low molecular weight polypeptide aqueous solution manufactured by hydrolyzing silk fibroin, and an aqueous binder hardened at 120 ° C or less. When several to several hundreds of nanometers of titanium oxide called photocatalyst hits ultraviolet rays of sunlight, electrons are excited by the photoelectric effect, electrons and holes are generated, and the electrons reduce oxygen in the air to superoxide ions. Holes oxidize surface moisture and turn them into hydroxyl radicals. The superoxide ion and hydroxyl radical exhibit strong oxidizing power, and when an organic substance adheres to the titania surface in this state, the superoxide ion decomposes the organic substance carbon and the hydroxyl radical takes hydrogen. Such a self-cleaning action is a mechanism that becomes an antibacterial action and a deodorizing action.

  In addition to the above documents, for example, JP-A-6-184808 discloses a permanent electrode fiber in which fine powdered tourmaline powder is blended with recycled fiber or synthetic fiber, and tourmaline crystals are highly oriented and distributed on the fiber surface. Alternatively, Japanese Patent Application Laid-Open No. 7-85861 discloses a coating fabric such as clothing that can improve the constitution and improve health by wearing underwear, and further, Japanese Utility Model Publication No. 5-22579 discloses a micronized electric A fiber product constructed as a material for artificial fibers containing a large number of stone crystals, or Japanese Utility Model Publication No. 7-3135, coating fabrics such as clothes, utility model registration No. 3017444, Functional fiber products having dielectric electrodes have been proposed. However, since negative ions emitted from tourmaline itself are weak, there is a problem that the effect cannot be expected so much. Further, Japanese Patent Application Laid-Open No. 7-149956 discloses a tourmaline-carrying rubber composition showing an electrode reaction in which tourmaline fine powder is kneaded and uniformly dispersed in a rubber elastic body having a specific volume resistivity. However, in most cases, the function is limited to a single function, and there is no suggestion about the convergence or the corresponding effect as well as the description of multiple or multi-functionality.

  Further, the document 1 emits a far infrared ray at the same time as emitting a negative ion containing a high molecular compound that is not easily charged with static electricity, a mineral containing rare elements, and at least one of tourmaline or a far infrared radiation ceramic. In the above-mentioned resin composition and the above-mentioned document 2, the stretchable woven or knitted fabric has a polymer base material that is not easily charged with static electricity, a single powder of mineral containing rare earth, or a mineral containing rare earth and tourmaline or distant. Disclosed is a multifunctional stretch woven or knitted fabric obtained by subjecting a resin composition obtained by mixing a mixed powder containing any one of infrared ceramic powders to surface processing or stripe or mesh coating processing or printing processing. Therefore, it is possible to use a far infrared ray that emits a large amount of negative ions and emits simultaneously. However, even if these have both antibacterial and deodorant functions, the action is weak and a special effect cannot be expected.

  In the above-mentioned document 3, an inorganic fine particle that generates negative ions on the fiber surface of the fabric is attached and processed using a binder resin, and a processed cloth that generates negative ions and its method. A coating composition that imparts the properties of silk to the above-mentioned fiber material and a fiber material imparted with the properties of silk by the application thereof are described.

  The document 3 is one in which a fabric is dipped in a processing liquid of fine inorganic particles, squeezed, and then dried and heat-treated. In the document 4, it is used as a binder for fixing a low molecular weight polypeptide. There is no explicit description or suggestion about the special knowledge about the binder resin in No. 2, and there is a lack of how to generate a large amount of negative ions. And also in the said literatures 3 and 4, both antibacterial and deodorant functions cannot be expected equally.

  The problem to be solved in the present invention is known to have an antibacterial effect and a deodorizing effect utilizing negative ions in recent research and the like. In the above-mentioned document 2, regarding the multifunctional woven and knitted fabrics and secondary products, especially when finding the effect of antibacterial action or deodorant action such as supporters, socks, underwear, and further antibacterial action, For garments such as these, an effect closer to sterilization than antibacterial is required. In addition, a high deodorizing effect is required in the deodorizing effect, in the underwear for elderly care facilities, and in the foul odor caused by the sock foot stuffiness.

  In view of the above-mentioned problems, a high molecular compound that is not easily charged with static electricity, a mineral containing rare elements, and a negative ion containing at least one of tourmaline or far-infrared ceramic are simultaneously emitted, and at the same time, far-infrared radiation is emitted. Focusing on the resin composition that has been added and mixed with the photocatalytic functional material to the resin composition to increase the antibacterial action and deodorant action, processing the supporter, socks, and underwear with the resin composition applied and fixed to the woven or knitted fabric The secondary product is able to exert health maintenance and antibacterial and deodorant effects by the simultaneous action of sustained release of negative ions and far infrared radiation, and further increase the antibacterial and deodorant effects by photocatalysis, We have arrived at knitted and knitted fabrics and secondary processed products that can be found in places where they are not exposed to sunlight and that have a multifunctional function that can be effective even at night.
