[Technical field]

[0001] The present invention relates to an iodine compound-supported organic polymer material which supports an iodine compound and has excellent durability when stored in an air atmosphere and when washed with water. [Background technology]

[0002] Conventionally, various anti-pathogenic textile products and anti-pathogenic plastic products have been proposed that have anti-pathogenic properties that kill or suppress the pathogenic ability of pathogens that have adverse effects on the human body, such as germs, viruses, molds, and bacteria.

[0003] As anti-pathogenic agents that confer anti-pathogenic properties against pathogens, various anti-pathogenic agents such as iodine compounds, pyridine compounds, phenolic compounds, silver compounds, copper compounds, and the like have been proposed, and products containing these anti-pathogenic agents have also been proposed.

[0004] As anti-pathogen agents, in particular, iodine compounds are known. For example, iodine tincture, made by dissolving iodine and potassium iodide in ethanol, is a dark reddish-brown liquid (described in the 15th revised Japanese Pharmacopoeia) and is commonly used as a disinfectant for human skin. Povidone-iodine, a complex of 1-vinyl-2-pyrrolidone polymer and iodine, is a dark reddish-brown powder that dissolves easily in water or ethanol (described in the 15th revised Japanese Pharmacopoeia), and liquids containing dissolved povidone-iodine are commonly used as disinfectants for the skin and mucous membranes and for disinfecting bacterially infected skin surfaces.

[0005] As an example of a fiber containing an iodine compound that has antibacterial or antifungal effects, Japanese Patent Application Laid-Open No. 6-192962 (Reference 1) discloses an antibacterial and antifungal processed polyester fiber obtained by imparting Nn-butylcarbamic acid 3-iodo-2-propynyl ester to a polyester fiber, and discloses that the fiber exhibits excellent antibacterial effects in antibacterial tests. Japanese Patent Application Laid-Open No. 2003-166155 (Reference 2) discloses a nonwoven fabric made of fibers including synthetic fibers such as polyester fibers, polyamide fibers, and polyolefin fibers to which antifungal agents such as organic iodine compounds, quaternary ammonium salts, and pyridine derivatives have been attached, and the nonwoven fabric is disclosed to have excellent antifungal properties.

[0006] On the other hand, for textile products containing antibacterial agents other than iodine compounds, the following antibacterial fibers have been proposed. Japanese Patent Application Laid-Open No. 2008-223182 (Reference 4) discloses antibacterial polyester long fibers containing an antibacterial agent mainly composed of silver zirconium phosphate.

[0008] Regarding antibacterial resin moldings, for example, Japanese Patent Laid-Open Publication No. 9-316355 (Reference 8) discloses a method for obtaining antibacterial resin moldings by mixing an antibacterial dry color with a natural resin and injection molding the mixture, the antibacterial dry color being composed of silica gel particles carrying a silver thiosulfato complex and pigment particles. JP2018-501412A (Reference 9) discloses a method for producing an antibacterial fabric, which includes the steps of immersing a fabric in an aqueous solution of an antibacterial metal salt such as copper iodide, copper sulfate, or copper chloride, and simultaneously irradiating the solution with ultrasonic waves.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, the method for producing an iodine-supported organic polymer material of the present invention and the iodine-supported organic polymer material will be described in terms of the mode for carrying out the invention. The method for producing an iodine-supported organic polymer material of the present invention is a method for producing an iodine-supported organic polymer material in which an iodine compound is supported on an organic polymer material, and in which desorption of the iodine compound from the organic polymer material is suppressed during washing with water and storage in an air atmosphere, and is characterized in that it comprises: (a) a step of supplying at least one organic polymer material selected from a chemically synthesized organic polymer material and a natural organic polymer material, wherein the organic polymer material has a nitrogen element in its chemical structural formula; (b) a step of preparing an iodine-comprising solution by dissolving an iodine compound in a solvent; (c) a step of contacting the iodine-comprising solution with the organic polymer material, thereby preparing an iodine-supported organic polymer material intermediate material containing the iodine compound; and (d) a step of removing the solvent from the iodine-supported organic polymer material intermediate material, thereby preparing an iodine-supported organic polymer material in which the iodine compound is supported on the organic polymer material. This manufacturing method has the effect of [Method effect A: an effect that an iodine-loaded organic polymer material can be easily manufactured by a simple and economically advantageous method, and that an iodine-loaded organic polymer material having long-term iodine-loading durability can be obtained by suppressing desorption of iodine compounds over a long period of time]: by the simple and economically advantageous method of "preparing an iodine-loaded organic polymer material intermediate material containing an iodine compound by contacting an iodine-containing solution obtained by dissolving an iodine compound in a solvent with an organic polymer material, and then removing the solvent from the iodine-loaded organic polymer material intermediate material", "the iodine-loaded organic polymer material can be easily manufactured by suppressing desorption of the supported iodine compound from the iodine-loaded organic polymer material during washing with water and storage in an air atmosphere at room temperature for a long period of time".

[0020] The iodine-supported organic polymer material of the present invention comprises (A) at least one organic polymer material selected from the group consisting of chemically synthesized organic polymer materials and natural organic polymer materials, and (B) an iodine compound, wherein the organic polymer material has a nitrogen element in its chemical structural formula, the iodine compound is supported by the organic polymer material, and desorption of the iodine compound from the organic polymer material is suppressed during washing with water and storage in an air atmosphere. This configuration provides the following effect: [Configuration effect A: Effect of having long-term iodine-loading durability with iodine compounds prevented from being released over a long period of time]: [Iodine compounds are firmly supported by the nitrogen elements of an organic polymer material containing nitrogen elements through some kind of chemical interaction, and an iodine-loaded organic polymer material is obtained in which iodine compounds are prevented from being released from the organic polymer material when washed with water and stored in an air atmosphere at room temperature for a long period of time].

[0021] The inventors have discovered the configuration and effects of the present invention through various experiments, and have found that "an iodine-loaded organic polymer material can be obtained in which, due to some interaction between the nitrogen element of an organic polymer material having a nitrogen element in its chemical structural formula and an iodine compound, desorption of the iodine compound from the iodine-loaded organic polymer material which loads the iodine compound is suppressed when the material is washed with water and stored in an air atmosphere at room temperature for a long period of time." The reason for the phenomenon that "the release of iodine compounds from iodine-loaded organic polymer materials that support iodine compounds is suppressed" is unclear, but it is thought to be due to the phenomenon that "the iodine compounds are firmly supported by the nitrogen element (chemical symbol: N) of the organic polymer material that contains the nitrogen element through some kind of chemical interaction."

[0022] In the above-mentioned method for producing an iodine-loaded organic polymer material and the above-mentioned iodine-loaded organic polymer material of the present invention, preferably, the above-mentioned "organic polymer material having a nitrogen element in the chemical structural formula is an "NH" bond or an "NH 2 " bond. This makes it possible to more significantly exert the aforementioned "Method Effect A" and "Configuration Effect A".

[0023] In the above-mentioned method for producing an iodine-supported organic polymer material of the present invention, it is possible to carry out a method for producing an iodine-supported organic polymer material having the following configuration. "The step (c) is a step of compounding the iodine compound in the iodine compound-containing solution with the nitrogen element of the organic polymer material through chemical interaction, thereby preparing an iodine-loaded organic polymer material intermediate material containing the iodine compound."

[0024] In the above-mentioned iodine-supported organic polymer material of the present invention, it is possible to preferably provide an iodine-supported organic polymer material having the following configuration. "The nitrogen element of the organic polymer material and the iodine compound are chemically interacted and complexed through ionic bonds, complex bonds, covalent bonds, or van der Waals bonds, and desorption of the iodine compound from the organic polymer material is suppressed during washing with water and storage in an air atmosphere." "The iodine compound supported on the polymer material has a form in which the iodine compound is supported on the polymer material by contact between the organic polymer material and an iodine compound-containing solution in which the iodine compound is dissolved in a solvent, and the iodine compound and the nitrogen element of the organic polymer material are complexed by chemical interaction, and desorption of the iodine compound from the organic polymer material is suppressed during washing with water and storage in an air atmosphere."

[0025] This configuration provides the above-mentioned [Method Effect A] and [Configuration Effect A], and further provides the following [Method Effect Aa] and [Configuration Effect Aa]. [Constituent Effect Aa]: The iodine compound dissolved in the solvent has a form such as iodine ion, iodine metal complex ion, iodine radical, iodine molecule, etc., and is considered to have a form that allows the iodine compound to be easily supported by the organic polymer material through some chemical interaction with the nitrogen element of the nitrogen-containing organic polymer material. For example, the iodine compound chemically interacts with the nitrogen element of the nitrogen-containing organic polymer material to obtain an iodine-supported organic polymer material in which the iodine compound and the nitrogen element are chemically complexed through chemical interactions such as ionic bonds, complex bonds, van der Waals bonds, covalent bonds, etc. [Method effect Aa]: The iodine-loaded organic polymer material having the above-mentioned "structural effect Aa" and long-term iodine-loading durability can be easily produced by a simple and economically advantageous method.

[0026] The iodine-loaded organic polymer material, which is a composite of an iodine compound and a nitrogen element through chemical interaction, is prevented from desorbing the loaded iodine compound from the iodine-loaded organic polymer material when washed with water and stored in an air atmosphere at room temperature for a long period of time, thereby achieving the effect of having iodine loading durability for a long period of time. For example, when potassium iodide and iodine molecules are dissolved in a solvent, iodine takes the form of a polyiodine ion consisting of a triiodide ion and an iodine molecule, and this polyiodine ion is formed as a counter ion adduct of the nitrogen element of the organic polymer material, and it is conceivable that an iodine-loaded organic polymer material is formed by complexing the polyiodine with the nitrogen element of the organic polymer material through chemical interaction. In addition, when povidone-iodine is dissolved in a solvent, the iodine in the povidone-iodine has the form of a polyiodine ion, and this polyiodine ion is formed as a counter ion adduct of the nitrogen element of the organic polymer material, and it is thought that an iodine-loaded organic polymer material is formed by complexing the polyiodine and the nitrogen element of the organic polymer material through chemical interaction. Polyiodide ions are, for example, [I 3 - ] is said to be the case.

[0027] In the method for producing the iodine-supported organic polymer material of the present invention, the step (c) preferably includes the following step (c-1), step (c-2), or step (c-3). (c-1) A step of immersing the organic polymer material in the solution containing the iodine compound, and then removing the organic polymer material from the solution containing the iodine compound, thereby preparing an iodine-loaded organic polymer material intermediate containing the iodine compound. (c-2) A step of applying the iodine compound-containing solution to the organic polymer material by showering, misting or spraying, thereby preparing an iodine-carrying organic polymer material intermediate material containing the iodine compound. (c-3) A step of contacting the organic polymer material with a brush, cloth material, or sponge material retaining the iodine compound-containing solution, thereby preparing an iodine-carrying organic polymer material intermediate material containing the iodine compound.

[0028] This configuration provides the effect of easily producing, by a simple, convenient, and economically advantageous method, an iodine-loaded organic polymer material having the aforementioned "Method Effect A" and "Method Effect Aa," which has a long-term iodine-loaded durability in which iodine compounds are prevented from being released from the organic polymer material when washed with water and stored in an air atmosphere, by providing a process in which an iodine-compound-containing solution and an organic polymer material are brought into contact with each other by means of "immersion," "showering, misting, or spraying," or "contact with a brush, cloth, or sponge material."

[0029] In the method for producing the iodine-loaded organic polymer material of the present invention, the steps (c) and (d) preferably include the following steps (cd), (cd-1), (cd-2), or (cd-3): (cd) step: in the (c) step, the temperature of the iodine compound-containing solution is about 30°C or less, and / or the time for which the iodine compound-containing solution and the organic polymer material are brought into contact with each other is about 5 minutes or less, thereby preparing an iodine-loaded polymer intermediate material in which the iodine compound is loaded into the polymer material, and in the (d) step, the solvent is removed from the iodine-loaded polymer intermediate material at a temperature of 30°C or less, thereby preparing an iodine-loaded polymer material in which the iodine compound is loaded on the organic polymer material. (cd-1) step: in the step (c), the organic polymer material is immersed in an iodine-containing solution having a temperature of about 30°C or less, in which the iodine compound is dissolved in a solvent, for a time period of about 5 minutes or less, thereby preparing an iodine-supported organic polymer material intermediate material in which the iodine compound is contained in the organic polymer material, and in the step (d), the solvent is removed from the iodine-supported organic polymer material intermediate material at a temperature of 30°C or less, thereby preparing an iodine-supported polymer material in which the iodine compound is supported on the organic polymer material. (cd-2) step: in the step (c), an iodine-compound-containing solution having a temperature of about 30°C or less, in which the iodine compound is dissolved in a solvent, is applied to the organic polymer material by showering, misting or spraying for a time period of about 5 minutes or less, thereby preparing an iodine-supported organic polymer material intermediate material in which the iodine compound is contained in the organic polymer material, and in the step (d), the solvent is removed from the iodine-supported organic polymer material intermediate material at a temperature of 30°C or less, thereby preparing an iodine-supported organic polymer material in which the iodine compound is supported on the organic polymer material. (cd-3) step: in the (c) step, a brush, cloth material, or sponge material holding the iodine compound-containing solution having a temperature of about 30°C or less is brought into contact with the organic polymer material for a time of about 5 minutes or less, thereby preparing an iodine-loaded polymer intermediate material in which the iodine compound is contained in the organic polymer material, and in the (d) step, the solvent is removed from the iodine-loaded polymer intermediate material at a temperature of 30°C or less, thereby preparing an iodine-loaded polymer material in which the iodine compound is loaded on the organic polymer material.

[0030] Particularly preferably, in the step (cd), the step (cd-1), the step (cd-2), or the step (cd-3), the temperature of the iodine compound-containing solution is preferably "a temperature of about 10°C to about 30°C."

[0031] This configuration provides the effect of easily producing an iodine-loaded organic polymer material having long-term iodine-loading durability, which has the above-mentioned "Method Effect A" and "Method Effect Aa", in a more remarkable, simple, and economically advantageous manner by a method in which an iodine-compound-containing solution and an organic polymer material are "contacted," "immersed," "attached by showering, misting, or spraying," or "contacted by brush, cloth, or sponge material" under conditions of "a temperature of about 30°C or less" and / or "a time of about 5 minutes or less."

[0032] The present invention has discovered that even when the temperature of the iodine compound-containing solution and the organic polymer material is about 30°C or lower and the contact time between the iodine compound-containing solution and the organic polymer material is within 5 minutes, the iodine compound and the organic polymer material form a complex through some kind of chemical interaction to form an iodine-loaded organic polymer material, and that this iodine-loaded organic polymer material has the property that desorption of the iodine compound from the organic polymer material is suppressed when washed with water and stored in an air atmosphere. In particular, "a temperature of about 10°C to about 30°C or less" refers to a temperature near or near room temperature without heating or cooling, and in particular, there is no need to heat or cool the iodine-compound-containing solution and / or the organic polymer material. By contacting the iodine-compound-containing solution and the organic polymer material with each other at a temperature near or near room temperature, an iodine-supported polymer intermediate material containing an iodine compound in a polymer material can be prepared, and an iodine-supported organic polymer material can be produced in which desorption of the iodine compound from the organic polymer material is suppressed during washing with water and storage in an air atmosphere. If the temperature of the iodine compound-containing solution is less than about 10° C., a step of cooling the iodine compound-containing solution is required, and the cost of the cooling step becomes high, which tends to result in high production costs.

[0033] Furthermore, even if the contact time between the iodine compound-containing solution and the organic polymer material is within 5 minutes, the iodine compound and the organic polymer material can form a complex through some kind of chemical interaction, thereby forming an iodine-loaded organic polymer material having the property of suppressing desorption of the iodine compound from the organic polymer material.

[0034] Particularly preferably, in the step (cd), the step (cd-1), the step (cd-2), or the step (cd-3), the time for which the iodine compound-containing solution and the polymeric material are brought into contact with each other is within about 30 seconds.More preferably, the time for which the iodine compound-containing solution and the polymeric material are brought into contact with each other is within about 10 seconds.

[0035] This configuration provides the effect of easily producing an iodine-loaded organic polymer material having long-term iodine-loading durability, which has the above-mentioned "Method Effect A" and "Method Effect Aa", by a method in which an iodine compound-containing solution and an organic polymer material are "contacted", "immersed", "attached by showering, misting or spraying", or "contacted by brush, cloth or sponge material" under the condition of "a time of about 30 seconds or less", in a simpler, more economically advantageous manner. The inventors have found through various experiments that the iodine compound can be easily supported on the organic polymer material even if the time for which the iodine compound-containing solution and the organic polymer material having a nitrogen element in its chemical structural formula are brought into contact with each other is within about 30 seconds. For example, it has been found that an iodine-loaded organic polymer material carrying an iodine compound can be easily prepared by the following methods: "immersing an organic polymer material in an iodine compound-containing solution for about 10 seconds or less," "showering or spraying the iodine compound-containing solution onto an organic polymer material for about 1 to 3 seconds, and then maintaining the iodine compound-containing solution attached to the organic polymer material for about 10 seconds or less without removing the solvent," or "contacting an organic polymer material with the iodine compound-containing solution for about 1 to 3 seconds using a brush, sponge, or the like, for about 1 to 3 seconds, and then maintaining the iodine compound-containing solution attached to the organic polymer material for about 10 seconds or less without removing the solvent."

[0036] <Chemically synthesized organic polymer materials> The above-mentioned method for producing an iodine-supported organic polymer material and the iodine-supported organic polymer material of the present invention preferably have the following configuration. "The chemically synthesized organic polymer material having a nitrogen element in its chemical structural formula is polyamide, polyurethane, polyacrylonitrile, polyimide, polyaramid, polyamideimide resin, urea resin, melamine resin, amine-containing epoxy resin, acrylonitrile-butadiene copolymer, acrylonitrile-styrene copolymer, acrylonitrile-butadiene-styrene copolymer, quaternary ammonium group-containing polymer, amide group-containing acrylic polymer, copolymer of quaternary ammonium group-containing polymer and other vinyl monomer, or copolymer of amide group-containing acrylic monomer and other vinyl monomer." "Moreover, it is particularly preferable that the chemically synthesized organic polymer material is a chemically synthesized organic polymer material having an amide group or a urethane group in its chemical structural formula."

[0037] The above-mentioned method for producing an iodine-supported organic polymer material has the above-mentioned [Method effect A] and [Method effect Aa], and also has the following [Method effect Ab]. [Method effect Ab: the effect of "obtaining an iodine-loaded organic polymer material that can be easily produced by a simple and economically advantageous method and has long-term iodine-loading durability in which iodine compound release is suppressed for a long period of time" as described above in the Method effect A is further significantly achieved.] In addition, these chemically synthesized organic polymer materials are mass-produced and widely used materials in the market, and can be supplied at low cost. From the viewpoint of industrial applicability, they have the advantage of being easily and inexpensively manufacturable.

[0038] The above-mentioned configuration of the iodine-supported organic polymer material provides the above-mentioned [Configuration Effect A] and [Configuration Effect Aa], and also provides the following effect [Configuration Effect Ab]. [Constituent effect Ab: the effect of "having long-term iodine-carrying durability with suppressed release of iodine compounds for a long period of time" of the aforementioned Constituent effect A is more significantly exhibited.] In addition, these chemically synthesized organic polymer materials are mass-produced and widely used in the market, and can be supplied at low cost, which is an advantage from an industrial point of view.

This configuration provides [constituent effect Ad: the aforementioned "constituent effect A" can be obtained, and an iodine-loaded organic polymer material can also exhibit the aforementioned "constituent effect Aa", "constituent effect Ab", and "constituent effect Ac" more significantly].

[0063] In the present invention, an iodine compound refers to a compound having an iodine element, the chemical symbol [I], in its chemical structure. Iodine refers to an element. As the iodine compound to be constituted, at least one iodine compound selected from the group consisting of iodine molecule (iodide), hydroiodic acid, potassium iodide, sodium iodide, silver iodide, copper iodide, potassium iodate, sodium iodate, and povidone iodine can be preferably used.

[0064] The properties of each iodine compound will be briefly described below.

[0065] The iodine molecule has the chemical formula [I 2 ] It is a purple-black solid with a melting point of 114 degrees and is highly soluble in aqueous potassium iodide solution. Potassium iodide has the chemical formula [KI], is a colorless solid with a melting point of 680°C, and is easily soluble in water. Iodine potassium iodide solution, in which iodine molecules are dissolved in potassium iodide aqueous solution, has a purple-black color and is commonly called iodine solution. In iodine potassium iodide solution, iodine is converted into triiodide ions [I 3 - It is said that the metal dissolves into water. Hydroiodic acid is an aqueous solution in which hydrogen iodide (boiling point -35°C) with the chemical formula [HI] is dissolved in water. Approximately 57% hydroiodic acid aqueous solution is widely used and has a reddish brown to yellow color.

[0066] Silver iodide, with the chemical formula AgI, is a yellow crystalline solid that dissolves in aqueous solutions of sodium thiosulfate or alkali metal iodides by forming complexes. Copper iodide has the chemical formula [CuI] and is a slightly yellow solid that has the property of forming a complex and dissolving in aqueous solutions of iodide salts such as potassium iodide or sodium iodide. Dilute iodine tincture, a dark reddish-brown liquid made by dissolving 30 g of iodine and 20 g of potassium iodide in 70 vol% ethanol (total volume 1000 mL), is a medicine listed in the Japanese Pharmacopoeia. Iodine tincture is commonly used as a disinfectant for human skin.

[0067] Potassium iodate has the chemical formula [KIO 3 Sodium iodate is a white powder with a melting point of 560°C and dissolves in potassium iodide solution. 3 ], it is a white powder with a melting point of 425°C and a solubility in water of 9.5g / 100ml.

[0068] Povidone iodine is a complex of polyvinylpyrrolidone (a polymer of 1-vinyl-2-pyrrolidone) and iodine, and is a medicinal drug (iodine preparation) listed in the Japanese Pharmacopoeia. It is a dark reddish-brown powder. Aqueous solutions of povidone iodine are clear brown in color, have antibacterial properties, and are commonly used as a disinfectant for the skin and mucous membranes and for disinfecting bacterially infected skin surfaces.

[0069] As described above, iodine compounds are known to have anti-pathogenic properties such as antibacterial properties, antiviral properties, and antifungal properties, and it is conceivable that an iodine-loaded organic polymer material in which an iodine compound is loaded onto an organic polymer material will have anti-pathogenic properties. The inventors conducted various experiments focusing on iodine compounds that have anti-pathogenic properties. As a result, they found that "organic polymer materials having a nitrogen element in their chemical structure have the property of easily supporting iodine compounds." They also found that "using the organic polymer material having the nitrogen element and an iodine compound, an iodine-supported organic polymer material that supports an iodine compound and has long-term iodine support durability to such an extent that elimination of iodine compounds from the organic polymer material is suppressed even when washed with water and stored in an air atmosphere can be produced by an industrially advantageous and easy method." As described above, the reason for the phenomenon that "the detachment of the iodine compound from the iodine-loaded organic polymer material that loads the iodine compound is suppressed" is not clear, but it is thought to be due to the phenomenon that "the iodine compound is firmly loaded onto the nitrogen element (chemical symbol: N) of the organic polymer material containing the nitrogen element through some kind of chemical interaction".

[0070] The inventors have confirmed through various experiments that "an iodine-supported organic polymer material in which an iodine compound is supported on an organic polymer material generally exhibits a light yellow, yellow, brown, reddish brown or dark brown color." In the present invention, the meanings of the terms brown, reddish brown, dark brown, etc., mean blackish brown, blackish deep red, blackish deep yellow, etc., and there is no clear difference between these brown colors. It is known that the content of iodine supported in an iodine-supported organic polymeric material can be measured by an oxidation-reduction titration method using an aqueous sodium thiosulfate solution. For example, the content of iodine as an oxidizing agent can be measured by an oxidation-reduction titration method using an aqueous sodium thiosulfate solution as a reducing agent and starch as an indicator. In the present invention, the content of iodine supported in the organic polymeric material is measured by this oxidation-reduction titration method to confirm the support of iodine.

There are a wide variety of woven fabrics depending on the type of thread, thickness, structure of the weave, density of the weave, and purpose. There are several types of weaving: plain weave, in which warp and weft threads are alternately crossed to form a tight weave; satin weave, in which either the warp or weft threads are left floating long on the surface of the fabric; and twill weave, in which three or more warp and weft threads are combined vertically and continuously to create diagonal lines (twill weave) on the surface of the fabric. Woven fabrics are also called woven cloth. Knitted fabrics are fabrics formed by combining threads into loops to form a flat surface, and are also called knit.

[0073] Nonwoven fabrics are sheet-like fabrics in which short or long fibers are entangled without being woven. Examples of nonwoven fabrics using short fibers include chemically bonded nonwoven fabrics in which fibers are entangled using an adhesive, thermally bonded nonwoven fabrics in which fibers are entangled using heat-fusible fibers, needle-punched nonwoven fabrics in which fibers are entangled using special needles, and spunlace nonwoven fabrics in which fibers are entangled using a high-pressure water stream. Examples of nonwoven fabrics using long fibers include spunbonded nonwoven fabrics made by spinning raw resin and then entangling the fibers through self-fusion, and meltblown nonwoven fabrics made by extruding raw resin at high pressure and blowing it away with hot air to form ultrafine nonwoven fabrics. The fiber aggregate is a fiber product having cushioning and heat insulating properties, in which short fibers and / or long fibers are aggregated without using a binder. For example, wool aggregates used as stuffing or filler for bedding and cold weather gear can be used.

The iodine-supported organic polymer intermediate material was taken out from the iodine compound-containing solution, and the taken out iodine-supported organic polymer intermediate material was placed in a 1-liter beaker, and 1000 mL of purified water at about 25°C was added to the beaker, and the mixture was stirred for 5 minutes to wash it, and then the iodine-supported organic polymer intermediate material was pressed between stainless steel wire mesh to remove the moisture. This washing experiment was repeated 5 times. Thereafter, the iodine-supported organic polymer material was placed on a wire net in a hot air dryer at about 30° C. for 24 hours or more to completely remove moisture and dry it. In this manner, the solvent contained in the iodine compound-containing solution was removed from the iodine-supported organic polymer material intermediate material by washing with water / drying, and each iodine-supported organic polymer material was prepared.

[0138] (Experiment 1a-e): Photographs were taken showing the appearance of the organic polymer material before contact with the iodine compound-containing solution, and the appearance of the iodine-loaded organic polymer material after contact with the iodine compound-containing solution. For each of the organic polymer materials used, photographs were taken to show the appearance of the organic polymer material before contact with the iodine compound-containing solution and the appearance of the iodine-loaded organic polymer material after contact with the iodine compound-containing solution obtained in "Experiments 1a-d." These photographs are shown in Figures 1 and 2.

[0139] In Figures 1 and 2, (Aa) is a photograph of a polyamide fiber woven fabric. (Ab) is a photograph of a blended fabric of polyurethane fiber and cotton fiber.

(Am) is a photograph of a polyethylene fiber woven fabric. (Ap) is a photograph of a polyester (polyethylene terephthalate) fiber woven fabric. (Ar) is a photograph of a cotton fiber woven fabric. (Aq) is a photograph of a rayon woven fabric. In the photographs for each sample, the left photograph is a photograph of the appearance of the organic polymer material before contacting it with the iodine compound-containing solution, and the right photograph is a photograph of the appearance of the iodine-loaded organic polymer material after it was contacted with the iodine compound-containing solution, washed with water to remove the solvent, and dried. (Aa), (Ab), (Abe), (Ad), and (Ae) are organic polymer materials that have a nitrogen element in their chemical structural formula, and (Am), (Ap), (Ar), and (Aq) are organic polymer materials that do not have a nitrogen element in their chemical structural formula.

[0140] In FIG. 1, the appearance of the iodine-loaded organic polymer material samples (Aa), (Ab), (Abe), (Ad), and (Ae) is yellow to brown, indicating that the iodine compound is loaded thereon. In contrast, the appearance of the organic polymer material after contact with the iodine compound-containing solution for each of the samples (Ae), (Am), (Ar), and (Aq) in Figure 2 is the same color as the appearance of the organic polymer material before contact with the iodine compound-containing solution, and it is clear that the iodine compound is not supported.

[0141] <Exemplary Example 1b> For each of the iodine-loaded organic polymer materials prepared in Typical Example 1a, the amount of iodine loaded on each of the organic polymer materials was measured and calculated by "iodine back titration" in the following experiment. (Experiment 1b-a): Preparation of starch indicator. Starch (1 g) and cold water (10 mL) were ground in a mortar with a pestle, and the resulting mixture was poured into boiling water (200 mL) while stirring, mixed, and then allowed to stand at room temperature to prepare a starch indicator. (Experiment 1b-b): Preparation of sodium thiosulfate solution. As a reagent, a 0.02 mol / L aqueous solution of sodium thiosulfate was provided and prepared by a reagent manufacturer. (Experiment 1b-c): Preparation of iodine solution. As a reagent, a 0.01 mol / L iodine solution was provided and prepared by a reagent manufacturer. (Experiment 1b-d): Preparation of sample solutions. For each of the iodine-supported organic polymer materials (rectangles 4 cm long and 5 cm wide) prepared in Typical Example 1, one iodine-supported organic polymer material was placed in an Erlenmeyer flask, and a 0.02 mol / L sodium thiosulfate aqueous solution (50 mL) was further added, and the iodine-supported organic polymer material was immersed in the sodium thiosulfate aqueous solution. As a result, the iodine-supported organic polymer material exhibited a bleached color.

[0142] (Experiments 1b-e): Measurement of iodine content by iodine back titration. Starch indicator (2 mL) was placed in a container, and then the sample solution (10 mL) prepared in "Experiment 1b-d" was added and mixed and stirred. This sample solution containing the starch indicator was titrated with 0.01 mol / L iodine solution, and the end point of the titration was the iodine solution that turned pale purple. The amount of iodine supported on the organic polymer material was calculated from the amount of iodine solution required to turn pale purple.

[0143] For each organic polymer material used, the amount of iodine supported in the iodine-loaded organic polymer material was measured and calculated by "iodine back titration" similar to "Experiment 1b-e". The measured and calculated "amount of iodine supported in the iodine-loaded organic polymer material after contact with the iodine compound-containing solution" is shown in Table 1 as the amount of iodine supported after the first washing.

[0144] Exemplary Example 1c A washing / drying experiment was carried out on each of the iodine-loaded organic polymer materials prepared by the above-mentioned "Typical Example 1a", in which washing and drying were repeated, and the amount of iodine loaded on each of the organic polymer materials after repeated washing / drying was measured and calculated by "iodine back titration". (Experiment 1c-a): Repeated washing / drying experiment of iodine-loaded organic polymer material (a). Among the iodine-loaded organic polymer materials prepared by the above-mentioned "Typical Example 1a", the remaining iodine-loaded organic polymer material used in the iodine back titration was placed in 1000 mL of purified water at about 25°C in a beaker, stirred for 5 minutes, and washed. The iodine-loaded organic polymer material was then pressed between stainless steel wire mesh to remove moisture. The iodine-loaded organic polymer material was then placed on a wire mesh in a hot air dryer at about 30°C for 12 hours or more to completely remove moisture and dry. In this way, a washed / dried iodine-loaded organic polymer material was prepared. This washing / drying experiment was repeated five times. This experiment was carried out on the following samples carrying iodine compounds: (Ab: mixed woven fabric of polyurethane fiber and cotton fiber), (Abe: mixed woven fabric of polyurethane fiber and polyester fiber), (Ad: wool fiber woven fabric), and (Ae: silk fiber woven fabric).

[0145] (Experiment 1c-b): Measurement of the amount of iodine supported on an iodine-loaded organic polymer material after five washing / drying cycles. For each of the iodine-loaded organic polymer materials prepared by the above "Experiment 1c-a", the amount of iodine loaded in the iodine-loaded organic polymer material was measured and calculated by "iodine back titration" similar to the above-mentioned "Typical Example 1b" using one piece of iodine-loaded organic polymer material. The calculated "amount of iodine loaded in the iodine-loaded organic polymer material after contact with the iodine compound-containing solution" is shown in Table 1 as the amount of iodine loaded after the fifth washing.

[0146] (Experiment 1c-c): Repeated washing / drying experiment of iodine-loaded organic polymer material (c). Of the iodine-loaded organic polymer materials prepared in the above "Experiment 1c-a", the iodine-loaded organic polymer materials, except for the iodine-loaded organic polymer material used in the iodine back titration, were placed in 1000 mL of purified water at about 25°C in a beaker, stirred for 5 minutes, and washed. After that, the iodine-loaded organic polymer materials were pressed between stainless steel wire mesh to remove moisture. The iodine-loaded organic polymer materials were then placed on a wire mesh in a hot air dryer at about 30°C for 12 hours or more to completely remove moisture and dry. In this way, each iodine-loaded organic polymer material after washing / drying was prepared. This washing / drying experiment was repeated five times, i.e., 10 washing / drying cycles in total were performed, including the five washing / drying cycles in the above experiment 1c-a and the five washing / drying cycles in this experiment.

[0147] (Experiment 1c-d): Measurement of the amount of iodine supported on the iodine-loaded organic polymer material after it was washed and dried 10 times. For each of the iodine-loaded organic polymer materials prepared in the above "Experiment 1c-c", one iodine-loaded organic polymer material was used to measure and calculate the amount of iodine loaded in the iodine-loaded organic polymer material by "iodine back titration" similar to the above "Typical Example 1b". The measured and calculated "amount of iodine loaded in the iodine-loaded organic polymer material" is shown in Table 1 as the amount of iodine loaded after the 10th washing / drying.

[0148] <Exemplary Example 1d> For each of the iodine-loaded organic polymer materials prepared by "Typical Example 1a", one iodine-loaded organic polymer material was stored in a room temperature atmosphere of 25°C and a relative humidity of 40 to 90% RH for 15 days, and the amount of iodine loaded in each organic polymer material after storage was measured and calculated by "iodine back titration". This experiment was carried out on the following samples carrying iodine compounds: (Ab: mixed woven fabric of polyurethane fiber and cotton fiber), (Abe: mixed woven fabric of polyurethane fiber and polyester fiber), (Ad: wool fiber woven fabric), and (Ae: silk fiber woven fabric). The measured and calculated "amount of iodine carried in the iodine-loaded organic polymer material" is shown in Table 1 as the amount of iodine carried after storage at room temperature for 15 days. In the "Iodine-supported or unsupported" column in Table 1, organic polymer materials that support iodine compounds are marked with an "O" mark, and organic polymer materials that do not support iodine compounds are marked with an "X" mark.

[0149] [Table 1]

[0150] In Table 1, the "amount of iodine supported per unit area" of the iodine-supported organic polymer material of each sample (Aa), (Ab), (Abe), (Ad), and (Ae) after the first cleaning was 0.06 mg / cm. 2 The "iodine loading per unit weight" was 3 mg / mg or more. In contrast, the "amount of iodine supported per unit area" of the iodine-supported organic polymer materials for each of the samples (Ae), (Am), (Ar), and (Aq) is 0.01 mg / cm. 2 and the "iodine loading per unit weight" was less than 1 mg / mg. In other words, it is understood that the organic polymer materials (Aa), (Ab), (Abe), (Ad), and (Ae), which are organic polymer materials having a nitrogen element in their chemical structural formula, form iodine-loaded organic polymer materials that load iodine, whereas the organic polymer materials (Am), (Ap), (Ar), and (Aq), which are organic polymer materials not having a nitrogen element in their chemical structural formula, do not load iodine.

[0151] The experimental result in typical Example 1b was the same as that in typical Example 1a described above, that is, "The iodine-supported organic polymer material samples (Aa), (Ab), (Abe), (Ad), and (Ae) shown in FIG. 1 were colored yellow to brown, indicating that they supported iodine compounds, whereas the appearance of the iodine-supported organic polymer material samples (Ae), (Am), (Ar), and (Aq) shown in FIG. 2 was the same color as the appearance of the organic polymer material before contact with the iodine compound-containing solution, indicating that no iodine compound was supported."

[0152] In Table 1, in the iodine-loaded organic polymer materials of the samples (Aa), (Ab), (Abe), (Ad), and (Ae), the amount of iodine loaded after the fifth washing and / or the amount of iodine loaded after the tenth washing remained at about 80% or more compared to the amount of iodine loaded after the first washing. In addition, the amount of iodine supported after storage for 15 days in a room temperature atmosphere of 25°C was almost unchanged compared to the amount of iodine supported after the first washing. The difference in the measured values ​​of the amount of iodine supported is thought to be due to the difference in measurement error. In other words, it is understood that each of the iodine-loaded organic polymer materials (Aa), (Ab), (Abe), (Ad), and (Ae) has the above-mentioned [constituent effect A: effect of having long-term iodine-loaded durability with iodine compounds suppressed from being released over a long period of time: effect of suppressing the release of the supported iodine compounds from the iodine-loaded organic polymer material during washing with water and storage in an air atmosphere at room temperature for a long period of time, thereby obtaining an iodine-loaded organic polymer material in which the iodine compounds are supported in the organic polymer material for a long period of time]. It is also understood that the above-mentioned [Method effect A: the effect of obtaining an iodine-loaded organic polymer material that can be easily produced by a simple and economically advantageous method and has long-term iodine-loading durability in which release of iodine compounds is suppressed] can be obtained.

[0153] <Exemplary Example 2a> In the following experiments, several types of iodine-supported organic polymer materials in the form of nonwoven fabric using fibers were prepared. (Experiment 2a-a): Prepare an organic polymer material in the form of a nonwoven fabric using fibers.

[0160] In FIG. 3, the appearance of the iodine-supported organic polymer material of the sample (Ba) is yellow to brown, and it is apparent that an iodine compound is supported. In contrast, the appearance of the organic polymer material of each of the samples (Bs), (Bp), (Bq), and (Bt) after contact with the iodine compound-containing solution was the same color as the appearance of the organic polymer material before contact with the iodine compound-containing solution, and it is clear that no iodine compound was supported on the organic polymer material.

[0161] <Exemplary Example 2b> For each of the iodine-loaded organic polymer materials prepared by Typical Example 2a, the amount of iodine loaded on each of the organic polymer materials was measured by the "iodine back titration" method similar to that of the above-mentioned "Typical Example 1b".

[0162] For each organic polymer material used, the amount of iodine supported in the iodine-loaded organic polymer material was measured and calculated by "iodine back titration" similar to the above-mentioned "Experiment 1b-e". The calculated "amount of iodine supported in the iodine-loaded organic polymer material after contact with the iodine compound-containing solution" is shown in Table 2 as the amount of iodine supported after the first washing.

[0163] Exemplary Example 2c For each of the iodine-loaded organic polymer materials prepared by "Typical Example 2a", a repeated washing experiment was carried out by a method similar to that of the above-mentioned "Typical Example 1c", and the amount of iodine loaded on each of the organic polymer materials after repeated washing was measured and calculated by "iodine back titration".

[0164] <Exemplary embodiment 2d> For each of the iodine-loaded organic polymer materials prepared by "Typical Example 2a", one iodine-loaded organic polymer material was stored for 15 days in a room temperature atmosphere of 25°C and a relative humidity of 40 to 90%RH, and the amount of iodine loaded in each organic polymer material after storage was measured and calculated by "iodine back titration". The measured and calculated "amount of iodine loaded in the iodine-loaded organic polymer material" is shown in Table 2 as the amount of iodine loaded after storage at room temperature for 15 days.

[0165] [Table 2]

[0166] In Table 2, the "amount of iodine carried per unit area" of the iodine-loaded organic polymer material of sample (Ba) is 0.16 mg / cm 2 The "amount of iodine carried per unit weight" was 39.6 mg / mg or more. In contrast, the "amount of iodine carried per unit area" of the iodine-loaded organic polymer material for each of the samples (Bs), (Bp), (Bq), and (Bt) is 0.01 mg / cm. 2 and the "iodine loading per unit weight" was less than 1 mg / mg. In other words, it is understood that (Ba), an organic polymer material having a nitrogen element in its chemical structural formula, forms an iodine-loaded organic polymer material that loads iodine, whereas (Bs), (Bp), (Bq) and (Bt), which are organic polymer materials not having a nitrogen element in their chemical structural formula, do not load iodine.

[0167] The experimental result in "Typical Example 2b" was the same as that shown in FIG. 3 in "Typical Example 2a" described above, in which "the iodine-loaded organic polymer material of sample (Ba) was colored yellow to brown, indicating that it carried iodine compounds, whereas the appearance of the iodine-loaded organic polymer material of each of samples (Bs), (Bp), (Bq), and (Bt) was the same color as the appearance of the organic polymer material before contact with the iodine compound-containing solution, indicating that no iodine compounds were carried."

[0168] In Table 2, in the iodine-loaded organic polymer material of sample (Ba), the amount of iodine loaded after the fifth washing was almost unchanged compared to the amount of iodine loaded after the first washing. The amount of iodine loaded after the tenth washing slightly decreased, but remained at about 80% or more. In addition, the amount of iodine supported after storage for 15 days in a room temperature atmosphere of 25°C was almost unchanged compared to the amount of iodine supported after the first washing. The difference in the measured values ​​of the amount of iodine supported is thought to be due to the difference in measurement error. That is, it is understood that the iodine-loaded organic polymer material (Ba) has the above-mentioned [constituent effect A: effect of having long-term iodine-loaded durability with iodine compounds suppressed from being released for a long period of time: effect of suppressing the release of the supported iodine compounds from the iodine-loaded organic polymer material during washing with water and storage in an air atmosphere at room temperature for a long period of time, thereby obtaining an iodine-loaded organic polymer material in which the iodine compounds are supported in the organic polymer material for a long period of time].

The measured and calculated "amount of iodine loaded in iodine-loaded organic polymer material" is shown in Table 3 as the amount of iodine loaded after storage at room temperature for 15 days.

[0180] [Table 3]

[0181] In Table 3, the "amount of iodine supported per unit area" of the iodine-supported organic polymer material for each of the samples (Ca), (Cb), and (Ch) is 0.05 mg / cm 2 The "iodine loading per unit weight" was 7.78 mg / mg or more. In contrast, the "amount of iodine carried per unit area" of the iodine-loaded organic polymer material of each sample (Cm) and (Cp) is 0.01 mg / cm 2 and the "iodine loading per unit weight" was less than 1 mg / mg. That is, it is understood that each of the samples (Ca), (Cb), and (Ch), which are organic polymer materials having a nitrogen element in their chemical structure, forms an iodine-loaded organic polymer material that loads iodine, whereas each of the samples (Cm) and (Cp), which are organic polymer materials not having a nitrogen element in their chemical structure, does not load iodine.

[0182] The experimental result in typical Example 3b was the same as that shown in FIG. 4 in typical Example 3a described above, in which "it is apparent that the iodine-loaded organic polymer materials of the samples (Ca), (Cb), and (Ch) are colored yellow to brown, indicating that they load iodine compounds, whereas the appearance of the organic polymer materials of the samples (Cm) and (Cp) after contact with the iodine compound-containing solution was the same color as that of the organic polymer materials before contact with the iodine compound-containing solution, indicating that no iodine compounds are loaded."

[0183] In Table 3, for the iodine-loaded organic polymer materials of samples (Ca), (Cb), and (Ch), the amount of iodine loaded after the fifth wash was almost unchanged compared to the amount loaded after the first wash. The amount of iodine loaded after the tenth wash was slightly reduced, but remained at about 80% or more. In addition, the amount of iodine loaded after storage for 15 days in a room temperature atmosphere of 25°C was almost unchanged compared to the amount of iodine loaded after the first wash. The difference in the measured values ​​of the amount of iodine loaded is thought to be due to differences in measurement errors.

[0190] In FIG. 5, after each of the samples (Dba) and (Dbb) was brought into contact with a solution containing an iodine compound, the appearance of each of the iodine-supported organic polymer materials was yellow to brown, indicating that the iodine compound was supported. In contrast, the appearance of the organic polymer material after each of the samples (Dv) and (Dw) not shown in the figure was brought into contact with the iodine compound-containing solution was the same color as the appearance of the organic polymer material before contact with the iodine compound-containing solution, confirming that the iodine compound was not supported.

[0191] Exemplary Example 4b For each of the iodine-loaded organic polymer materials prepared by "Typical Example 4a", the amount of iodine loaded on each of the organic polymer materials was measured by the "iodine back titration" method similar to that of the above-mentioned "Typical Example 1b".

[0192] For each of the organic polymer materials used, the amount of iodine carried in the iodine-loaded organic polymer material after contact with the solution containing an iodine compound, as measured by iodine back titration, is shown in Table 4.

[0193] Exemplary Example 4c For each of the iodine-loaded organic polymer materials prepared by "Typical Example 4a", a washing / drying repeat experiment was carried out by a method similar to that of the above-mentioned "Typical Example 1c", and the amount of iodine loaded on each of the organic polymer materials after the repeated washing / drying was measured and calculated by "iodine back titration". The measured and calculated "amount of iodine carried by the iodine-loaded organic polymer material" is shown in Table 4 as the amount of iodine carried after the fifth washing and the amount of iodine carried after the tenth washing.

[0194] <Exemplary embodiment 4d> For each of the iodine-loaded organic polymer materials prepared by "Typical Example 4a", one iodine-loaded organic polymer material was stored for 15 days in a room temperature atmosphere of 25°C and a relative humidity of 40 to 90%RH, and the amount of iodine loaded in each organic polymer material after storage was measured and calculated by "iodine back titration". The measured and calculated "amount of iodine loaded in the iodine-loaded organic polymer material" is shown in Table 4 as the amount of iodine loaded after storage at room temperature for 15 days.

[0195] [Table 4]

[0196] In Table 4, the "iodine loading per unit area" of the iodine-loaded organic polymer material of each sample (Dba) and (Dbb) is 0.06 mg / cm 2 The "amount of iodine carried per unit weight" was 6 mg / mg or more. In contrast, the "amount of iodine carried per unit area" of the iodine-loaded organic polymer material of each sample (Dv) and (Dw) is 0.01 mg / cm 2 and the "iodine loading per unit weight" was less than 1 mg / mg. In other words, it is understood that the organic polymer materials (Dba) and (Dbb), which have a nitrogen element in their chemical structural formula, form iodine-loaded organic polymer materials that load iodine, whereas the organic polymer materials (Dv) and (Dw), which do not have a nitrogen element in their chemical structural formula, do not load iodine.

[0197] The experimental result in typical Example 4b was the same as that shown in FIG. 5 in typical Example 4a described above, in which "after each of the samples (Dba) and (Dbb) was brought into contact with the iodine compound-containing solution, the iodine-supported organic polymer material was colored brown, indicating that the iodine compound was supported thereon. In contrast, the appearance of each of the samples (Dv) and (Dw) after contact with the iodine compound-containing solution was the same color as the appearance of the organic polymer material before contact with the iodine compound-containing solution, indicating that the iodine compound was not supported thereon."

[0198] In Table 4, in each of the iodine-loaded organic polymer materials (Dba) and (Dbb), the amount of iodine loaded after the fifth washing and / or the amount of iodine loaded after the tenth washing remained at about 80% or more compared to the amount of iodine loaded after the first washing. In addition, the amount of iodine supported after storage for 15 days in a room temperature atmosphere of 25° C. was almost unchanged compared to the amount of iodine supported after the first washing. In other words, it is understood that each of the iodine-loaded organic polymer materials (Dba) and (Dbb) has the above-mentioned [constituent effect A: effect of having long-term iodine-loaded durability with iodine compounds suppressed from being released over a long period of time: effect of suppressing the release of the supported iodine compounds from the iodine-loaded organic polymer material during washing with water and storage in an air atmosphere at room temperature for a long period of time, thereby obtaining an iodine-loaded organic polymer material in which the iodine compounds are supported in the organic polymer material for a long period of time]. It is also understood that the above-mentioned [Method effect A: the effect of obtaining an iodine-loaded organic polymer material that can be easily produced by a simple and economically advantageous method and has long-term iodine-loading durability in which release of iodine compounds is suppressed] can be obtained.

[0199] Exemplary Example 5a In the following experiments, an iodine-potassium iodide-containing solution containing iodine and potassium iodide was used as the iodine compound-containing solution to prepare several types of iodine-supported organic polymer materials in the form of a woven fabric, a film, and a foam using fibers. (Experiment 5a-a): Prepare organic polymer materials in the form of fiber-based fabrics, films, and foams. The following various organic polymer materials were prepared, which are in the form of a woven fabric, film, or foam using fibers, and which have a nitrogen element in their chemical structure, and which do not have a nitrogen element in their chemical structure. Each organic polymer material was cut to prepare rectangular test pieces measuring 4 cm in length and 5 cm in width. Six test pieces were prepared for each organic polymer material.

[0202] (Experiment 5a-b): Prepare an iodine-potassium iodide solution as a solution containing iodine compounds. As the iodine potassium iodide solution, "0.01 mol / L iodine aqueous solution" manufactured by Fujifilm Wako Pure Chemical Industries, Ltd. was prepared. This 0.01 mol / L iodine solution contains 0.26 wt% iodine and 0.8 wt% potassium iodide. The iodine potassium iodide solution has a transparent dark reddish brown color. Purified water was added to 79 mL of the 0.01 mol / L iodine solution to prepare a total of 200 mL of iodine aqueous solution.

[0203] (Experiment 5a-c): Preparation of an iodine-loaded organic polymer material intermediate by contacting an organic polymer material with a solution containing an iodine compound. At room temperature of about 25°C, the iodine compound-containing solution (200 mL) prepared in Experiment 6-b was placed in a glass beaker, and each organic polymer material (size: length 4 cm, width 5 cm) prepared in Experiment 5-a was immersed in the iodine compound-containing solution for 3 minutes. During immersion, the iodine compound-containing solution was stirred and the organic polymer material was pressed with tweezers to bring the organic polymer material into sufficient contact with the iodine compound-containing solution. In this way, each iodine-loaded organic polymer material intermediate was prepared.

[0204] (Experiments 5a-d): Using a method similar to that of the above-mentioned "Examples 1a-d," the solvent contained in the iodine compound-containing solution was removed from the iodine-loaded organic polymer material intermediate material by washing with water and drying, and then each iodine-loaded organic polymer material was prepared by drying.

[0205] (Experiments 5a-e): For each of the organic polymer materials used, photographs were taken to show the appearance of the organic polymer material before contact with the iodine compound-containing solution and the appearance of the organic polymer material after contact with the iodine compound-containing solution obtained in "Experiments 5a-d." These photographs are shown in Figures 6 and 7.

[0206] In FIG. 6, after each of the samples (Ad), (Aa), (Ca), (Dba), and (Ae) was contacted with a solution containing an iodine compound, the appearance of the organic polymer material was yellow to brown, indicating that the iodine compound was supported thereon. In contrast, as shown in FIG. 7, the appearance of the organic polymer material after contacting each of the samples (Ap), (Cm), (Cp), (Dv), (Ar), and (Bs) with the iodine compound-containing solution was the same color as the appearance of the organic polymer material before contacting with the iodine compound-containing solution, confirming that the iodine compound was not supported.

[0207] Exemplary Example 5b For each of the iodine-loaded organic polymer materials prepared by "Typical Example 5a", the amount of iodine loaded on each of the organic polymer materials was measured by the "iodine back titration" method similar to that of the above-mentioned "Typical Example 1b".

[0208] For each of the organic polymer materials used, the amount of iodine carried in the iodine-loaded organic polymer material after contact with the solution containing an iodine compound, as measured by iodine back titration, is shown in Table 5.

[0209] Exemplary Example 5c For each of the iodine-loaded organic polymer materials prepared by "Typical Example 5a", a washing and drying repeat experiment was carried out by a method similar to that of the above-mentioned "Typical Example 1c", and the amount of iodine loaded on each of the organic polymer materials after the washing / drying repeat experiment was measured and calculated by "iodine back titration". The measured and calculated "amount of iodine loaded in the iodine-loaded organic polymer material" is shown in Table 5 as the amount of iodine loaded after the fifth washing and the amount of iodine loaded after the tenth washing.

[0210] <Exemplary Example 5d> For each of the iodine-loaded organic polymer materials prepared by "Typical Example 5a", one iodine-loaded organic polymer material was stored in a room temperature atmosphere of 25°C and a relative humidity of 40 to 90% RH for 15 days, and the amount of iodine loaded in each organic polymer material after storage was measured and calculated by "iodine back titration". The calculated "amount of iodine carried in the iodine-loaded organic polymer material" is shown in Table 5 as the amount of iodine carried after storage at room temperature for 15 days.

[0211] [Table 5]

[0212] In Table 5, the "amount of iodine carried per unit area" of the iodine-loaded organic polymer materials (Ad) fabric, (Aa) fabric, (Ca) film, (Dba) foam, and (Ae) fabric is 0.09 mg / cm. 2 The "amount of iodine carried per unit weight" was 20 mg / mg or more. In contrast, the "amount of iodine carried per unit area" of each of the iodine-loaded organic polymer materials, (Ap) textile, (Cm) film, (Cp) film, (Dv) foam, (Ar) textile, and (Bs) nonwoven fabric, is 0.01 mg / cm. 2 and the "iodine loading per unit weight" was less than 1 mg / mg. In other words, it is understood that the (Ad) woven fabric, (Aa) woven fabric, (Ca) film, (Dba) foam, and (Ae) woven fabric, which are organic polymer materials having a nitrogen element in their chemical structural formula, form iodine-loaded organic polymer materials that load iodine, whereas the (Ap) woven fabric, (Cm) film, (Cp) film, (Dv) foam, (Ar) woven fabric, and (Bs) nonwoven fabric, which are organic polymer materials not having a nitrogen element in their chemical structural formula, do not load iodine.

[0213] The experimental result in "Typical Example 5b" was the same as the experimental result shown in FIG. 6 in "Typical Example 5a" described above, which shows that "the iodine-loaded organic polymer materials of (Ad) fabric, (Aa) fabric, (Ca) film, (Dba) foam, and (Ae) fabric were colored yellow to brown, indicating that they loaded iodine compounds, whereas the appearance of the organic polymer materials after contacting each of the samples of (Ap) fabric, (Cm) film, (Cp) film, (Dv) foam, (Ar) fabric, and (Bs) nonwoven fabric with the iodine compound-containing solution shown in FIG. 7 was the same color as the appearance of the organic polymer materials before contacting with the iodine compound-containing solution, indicating that no iodine compounds were loaded."

[0214] In Table 5, in each of the iodine-loaded organic polymer materials, namely, (Ad) woven fabric, (Aa) woven fabric, (Ca) film, (Dba) foam, and (Ae) woven fabric, the amount of iodine loaded after the fifth washing and / or the amount of iodine loaded after the tenth washing remained at about 80% or more compared to the amount of iodine loaded after the first washing. In addition, the amount of iodine supported after storage for 15 days in a room temperature atmosphere of 25° C. was almost unchanged compared to the amount of iodine supported after the first washing. In other words, it is understood that each of the iodine-loaded organic polymer materials, namely, (Ad) fabric, (Aa) fabric, (Ca) film, (Dba) foam, and (Ae) fabric, has the above-mentioned [Constituent Effect A: Effect of having long-term iodine-loaded durability with long-term iodine compound desorption suppressed: effect of suppressing desorption of the supported iodine compounds from the iodine-loaded organic polymer material during washing with water and storage in an air atmosphere at room temperature for a long period of time, thereby obtaining an iodine-loaded organic polymer material in which the iodine compounds are supported in the organic polymer material for a long period of time]. It is also understood that the above-mentioned [Method effect A: the effect of obtaining an iodine-loaded organic polymer material that can be easily produced by a simple and economically advantageous method and has long-term iodine-loading durability in which release of iodine compounds is suppressed] can be obtained.

[0215] <Typical Example 6> The amount of iodine compounds carried in iodine-loaded organic polymer materials prepared using 100% povidone-iodine solution, 50% methanol solution, or 100% methanol solution was compared. (Experiment 6a-a) The organic polymer materials used were the wool fiber fabric (Ad) and polyamide fiber fabric (Aa) used in "Typical Example 1a", the polyamide film (Ca) used in "Typical Example 3a", and the polyurethane foam (Dba) used in "Typical Example 4a".

[0216] A 100% aqueous solution of povidone-iodine was prepared in the same manner as in "Experiment 1a-b" of "Typical Example 1a" above.

[0217] (Experiment 6a-ba): A povidone-iodine solution (50% methanol / 50% water solvent) was prepared as a solution containing an iodine compound. At room temperature of about 25°C, 2 g of povidone-iodine powder and 100 mL of methanol were weighed out and placed in a glass beaker, and the povidone-iodine was dissolved in methanol by stirring to prepare a methanol solution, and purified water was added to the methanol solution to prepare a total volume of 200 mL of povidone-iodine solution. In this way, a transparent dark reddish brown povidone-iodine solution (50% methanol / 50% water solvent) containing about 1% by weight of povidone-iodine (available iodine: 0.2 mg / mL) was prepared. (Experiment 6a-bb): A povidone-iodine solution (100% methanol solvent) was prepared as a solution containing an iodine compound. At room temperature of about 25°C, 2 g of povidone-iodine powder and 100 mL of methanol were weighed out and placed in a glass beaker, and the povidone-iodine was dissolved in methanol by stirring to prepare a methanol solution. Further methanol was added to the methanol solution to prepare a total volume of 200 mL of povidone-iodine solution. In this way, a transparent dark reddish brown povidone-iodine solution (100% methanol solvent) containing about 1% by weight of povidone-iodine (available iodine: 0.2 mg / mL) was prepared.

[0218] (Experiment 6a-c): Preparation of an iodine-loaded organic polymer material intermediate by contacting an organic polymer material with a solution containing an iodine compound. By a method similar to that of the above-mentioned "Examples 1a to 1c", each of the organic polymer materials was made to carry an iodine compound-containing solution, thereby preparing each of the iodine-supported organic polymer material intermediate materials.

[0219] (Experiment 6a-d): Preparation of iodine-loaded organic polymer material by removing the solvent from the iodine-loaded organic polymer material intermediate. In a manner similar to that of the above-mentioned "Examples 1a to 1d", the solvent was removed from the intermediate material of the iodine-supported organic polymer material to prepare the iodine-supported organic polymer material.

[0220] (Experiment 6a-e): Photographs were taken showing the appearance of the organic polymer material before contact with the iodine compound-containing solution, and the appearance of the iodine-loaded organic polymer material after contact with the iodine compound-containing solution. For each of the organic polymer materials used, photographs were taken to show the appearance of the organic polymer material before contact with the iodine compound-containing solution and the appearance of the iodine-loaded organic polymer material obtained in “Experiments 6a-d” after contact with the iodine compound-containing solution, and these photographs are shown in Figure 8.

[0221] Exemplary Example 6b For each of the iodine-loaded organic polymer materials prepared by "Typical Example 6a", the amount of iodine loaded on each of the organic polymer materials was measured by the "iodine back titration" method similar to that of the above-mentioned "Typical Example 1b". For each of the organic polymer materials used, the amount of iodine carried in the iodine-loaded organic polymer material after contact with the solution containing an iodine compound, as measured by iodine back titration, is shown in Table 6.

[0222] [Table 6]

[0223] The results of this experiment show that an iodine-supported organic polymer material that supports iodine can be obtained regardless of whether the iodine compound-containing solution is an aqueous solution, a methanol solution, or an aqueous ethanol solution. However, depending on the type of solvent in which povidone-iodine is dissolved, the amount of iodine compound carried by organic polymer materials such as wool fiber fabrics, polyamide fiber fabrics, polyamide films, and polyurethane foams varies slightly.

[0224] When the organic polymer material was a wool fiber woven fabric, an iodine compound-containing solution containing water as a solvent carried a larger amount of iodine compound than an iodine compound-containing solution containing a mixed solvent of water and alcohol or an alcohol solvent.

[0225] When the organic polymer material was a polyamide fiber fabric, a polyamide film, or a polyurethane foam, no significant difference in the amount of iodine carried was observed in the iodine compound-containing solutions containing water, water and alcohol, or alcohol as the solvent, but there was a tendency for the amount of iodine compounds to increase slightly as the alcohol content increased.

[0226] That is, when the organic polymer material is a natural organic polymer material such as a wool fiber woven fabric, an iodine compound-containing solution containing water as a solvent carried a larger amount of iodine compound than an iodine compound-containing solution containing a mixed solvent of water and alcohol or an alcohol solvent. Furthermore, when the organic polymer material was a chemically synthesized organic polymer material such as a polyamide fiber woven fabric, a polyamide film, or a polyurethane foam, no significant difference in the amount of iodine carried was observed, but there was a tendency for the amount of iodine compounds to increase slightly as the alcohol content increased.

[0227] <Exemplary Example 7> As the iodine compound-containing solutions, a 10% povidone-iodine solution containing 10% povidone-iodine and a 1% povidone-iodine solution containing 1% povidone-iodine were used to prepare iodine-loaded organic polymer materials in the form of woven fabrics using fibers. (Experiment 7a-a) The organic polymer materials used were the wool fiber fabric (Ad) and polyamide fiber fabric (Aa) used in "Typical Example 1a", the polyamide film (Ca) used in "Typical Example 3a", and the polyurethane foam (Dba) used in "Typical Example 4a".

[0228] (Experiment 7a-b): Prepare a 10% povidone-iodine solution as a solution containing an iodine compound. A 10% povidone-iodine solution was prepared as an iodine compound-containing solution by dissolving an iodine compound in a solvent as described below. At room temperature of about 25°C, 20g of povidone-iodine powder and 10mL of purified water were weighed out and mixed in a glass beaker to dissolve povidone-iodine in purified water to prepare an aqueous solution, and purified water was further added to the aqueous solution to prepare a total of 200mL of povidone-iodine solution.In this way, a povidone-iodine solution containing 10% by weight of povidone-iodine was prepared.The povidone-iodine powder used had a dark reddish brown color, and the prepared povidone-iodine solution had a transparent dark reddish brown color, and it was confirmed that the povidone-iodine powder was completely dissolved in purified water.In this way, a 10% iodine compound-containing solution was prepared.

[0229] (Experiment 1a-b): Prepare a 1% povidone-iodine solution as a solution containing an iodine compound. A 1% povidone-iodine solution was prepared in the same manner as in "Experiment 1a-b" above.

[0230] Using the respective iodine compound-containing solutions, 3% iodine compound solution and 1% povidone-iodine solution, iodine-loaded organic polymer materials were prepared by methods similar to those described above in "Examples 1a-c," "Examples 1a-d," and "Examples 1a-d."

[0231] Exemplary Example 7b For each of the iodine-loaded organic polymer materials prepared by "Typical Example 7a", the amount of iodine loaded on each of the organic polymer materials was measured by the "iodine back titration" method similar to that of the above-mentioned "Typical Example 1b".

[0232] For each of the organic polymer materials used, the amount of iodine carried in the iodine-loaded organic polymer material after contact with the solution containing an iodine compound, as measured by iodine back titration, is shown in Table 7.

[0233] [Table 7]

[0234] In Table 7, for each of the iodine-loaded organic polymer materials, (Ad) fabric, (Aa) fabric, (Ca) film, and (Dba) foam, the samples that came into contact with a 10% povidone-iodine solution (samples immersed in a 10% povidone-iodine solution) had a greater amount of iodine loaded than the samples that came into contact with a 1% povidone-iodine solution (samples immersed in a 1% povidone-iodine solution). That is, it is understood that when the iodine concentration of the iodine compound-containing solution is high, an iodine-supported organic polymer material having a larger amount of iodine supported can be obtained than when the iodine concentration of the iodine compound-containing solution is low.

[0235] <Exemplary Example 8> An iodine-loaded organic polymer material was prepared by impregnating a polyamide fiber fabric with a 10% povidone-iodine aqueous solution. The material was washed with water 30 times, and the appearance of the iodine-loaded organic polymer material after the repeated washing with water was observed and the amount of iodine loaded was measured.

[0236] (Experiment 8a-a): Aa (polyamide fiber fabric, manufactured by WAVOU Co., Ltd., SMD-FR30, colorless) bolt was cut to prepare a polyamide fiber fabric having a width of 110 cm and a length of 100 cm. (Experiment 8a-b): 500 g of povidone-iodine powder was added to a polyethylene beaker containing 5 L of purified water and stirred to prepare a transparent, brown iodine-containing solution (10% povidone-iodine aqueous solution).

[0237] (Experiment 8a-c): The polyamide fiber fabric prepared in "Experiment 8a-a" was immersed for 3 minutes in the povidone-iodine aqueous solution prepared in "Experiment 8a-b" so that the entire polyamide fiber fabric was sufficiently in contact with and infiltrated by the povidone-iodine aqueous solution, thus preparing an iodine-loaded organic polymer material intermediate.

[0238] (Experiment 8a-d): The iodine-carrying organic polymer intermediate material was taken out from the iodine compound-containing solution, and the taken out iodine-carrying organic polymer intermediate material was placed in a 22 L polyethylene container, and 20 L of purified water at about 25°C was added to the polyethylene container, and the mixture was stirred for 5 minutes to wash it, and then the iodine-carrying organic polymer intermediate material was pressed between stainless steel wire mesh to remove moisture. The iodine-carrying organic polymer intermediate material was then placed on the wire mesh in a hot air dryer at about 30°C for 24 hours or more to completely remove moisture and dry it. In this way, a polyamide fiber woven fabric carrying an iodine compound was prepared as an iodine-loaded organic polymer material having a width of 110 cm and a length of 100 cm. The prepared polyamide fiber woven fabric had a brown color. This polyamide fiber woven fabric carrying the iodine compound was cut to prepare a plurality of iodine-carrying organic polymer materials carrying the iodine compound, each of which was 15 cm long and 15 cm wide.

[0239] Exemplary Example 8b For one of the multiple iodine-loaded organic polymer materials prepared by "Typical Example 8a", the amount of iodine loaded on each organic polymer material was measured by the "iodine back titration" method similar to that of the above-mentioned "Typical Example 1b".

[0240] Exemplary Example 8c A number of pieces of iodine-loaded organic polymer materials prepared by "Exemplary Example 8a" were washed with tap water containing a neutral detergent for 5 minutes while stirring in a washing machine, then dehydrated by centrifugal dehydration in the washing machine, further washed with tap water, dehydrated, and then dried with hot air. This washing procedure was repeated for multiple iodine-loaded organic polymer materials 1, 5, 10, 15, 20, 25, and 30 times. Photographs of the appearance of each iodine-loaded organic polymer material after repeated washing are shown in Figure 9. It can be seen from FIG. 9 that the appearance of the iodine-supported organic polymer material changes from brown to yellow and then to pale yellow by repeating washing / drying.

[0241] Furthermore, the amount of iodine supported on each organic polymer material after 1, 5, 10, 20, and 30 washing / drying cycles was measured and calculated by "iodine back titration." The measured and calculated "amount of iodine supported on iodine-supported organic polymer material" is shown in Table 8. In addition, one iodine-loaded organic polymer material was stored for 15 days in a room temperature atmosphere at 25°C and a relative humidity of 40 to 90%RH, and the amount of iodine loaded in each organic polymer material after storage was measured and calculated by "iodine back titration." The calculated "amount of iodine loaded in iodine-loaded organic polymer material" is shown in Table 8 as the amount of iodine loaded after storage at room temperature for 15 days.

[0242] [Table 8]

[0243] In Table 8, the amount of iodine carried by the iodine-loaded organic polymer material after 10 cycles of washing / drying was slightly reduced compared to the amount of iodine carried by the first washing, but remained at about 80% or more. Furthermore, the amount of iodine carried by the iodine-loaded organic polymer material after 30 cycles of washing and drying remained at approximately 50% or more compared to the amount of iodine carried after the first washing. In addition, the amount of iodine supported after storage for 15 days in a room temperature atmosphere of 25°C was almost unchanged compared to the amount of iodine supported after the first washing. The difference in the measured values ​​of the amount of iodine supported is thought to be due to the difference in measurement error. In other words, it can be seen that the iodine-loaded organic polymer material prepared by immersing an organic polymer material in a high-concentration 10% povidone-iodine aqueous solution can obtain the above-mentioned [Constituent Effect A: Effect of having long-term iodine-loaded durability with long-term iodine compound release suppressed: when washed with water and stored in an air atmosphere at room temperature for a long period of time, release of the supported iodine compounds from the iodine-loaded organic polymer material is suppressed, resulting in an iodine-loaded organic polymer material in which the iodine compounds are supported by the organic polymer material for a long period of time], just like the iodine-loaded organic polymer material prepared by immersing the organic polymer material in a low-concentration 1% povidone-iodine aqueous solution.

[0244] <Exemplary Example 9> The amount of the iodine compound supported in the iodine-supported organic polymer material produced by changing the contact time between the organic polymer material having nitrogen atoms and the solution containing the iodine compound was measured. As the organic polymer materials, the wool fiber woven fabric (Ad) and polyamide fiber woven fabric (Aa) used in "Typical Example 1a", the polyamide fiber nonwoven fabric (Ba) used in "Typical Example 2a", the polyamide film (Ca) used in "Typical Example 3a", and the polyurethane foam (Dba) used in "Typical Example 4a" were used. As the iodine compound-containing solution, the povidone-iodine solution used in "Typical Examples 1a to 4a" was used.

[0245] In the experiment of "Preparation of iodine-supported organic polymer material intermediate material by contacting organic polymer material with iodine compound-containing solution" which is a method similar to "Typical Example 1a to Typical Example 4a", an iodine compound-containing solution (200 mL) was placed in a glass beaker at room temperature of about 25°C, and an organic polymer material (size: length 4 cm, width 5 cm) was immersed in the iodine compound-containing solution for a predetermined time (10 seconds, 5 minutes, 15 minutes). During immersion, the iodine compound-containing solution was stirred and the organic polymer material was pressed with tweezers to sufficiently contact the organic polymer material with the iodine compound-containing solution. In this way, each iodine-supported organic polymer material intermediate material was prepared. Using each of the iodine-supported organic polymer material intermediates thus prepared, each of the iodine-supported organic polymer materials was prepared in a manner similar to that of "Typical Example 1a to Typical Example 4a."

[0246] The amount of iodine supported on each of the iodine-loaded organic polymer materials prepared above was measured by the "iodine back titration" method similar to that of the above-mentioned "Typical Example 1b". For each of the organic polymer materials used, the "amount of iodine supported on the iodine-loaded organic polymer material after contact with the iodine compound-containing solution" measured by "iodine back titration" is shown in Table 9.

[0247] [Table 9]

[0248] In Table 9, when the wool fiber fabric (Ad) was immersed in the iodine compound-containing solution for a given time (10 seconds, 5 minutes, 10 minutes), the amount of iodine supported was almost the same. When the polyamide fiber woven fabric (Aa) was immersed in the iodine compound-containing solution for a predetermined time (10 seconds, 5 minutes, and 10 minutes), the amount of iodine supported was almost the same. When the polyamide nonwoven fabric (Ba) was immersed in the iodine compound-containing solution for a given time (10 seconds, 5 minutes, and 10 minutes), the amount of iodine supported was almost the same. When the polyamide film (Ca) was immersed in the iodine compound-containing solution for a given time (10 seconds, 5 minutes, and 10 minutes), the amount of iodine supported was almost the same. When the polyurethane foam (Dba) was immersed in the iodine compound-containing solution for a given time (10 seconds, 5 minutes, and 10 minutes), the amount of iodine supported was almost the same.

[0249] In other words, the amount of iodine supported when the organic polymer material was immersed in the iodine compound-containing solution for 10 seconds was almost the same as that when it was immersed in the iodine compound-containing solution for 15 minutes. From this experimental result, it is understood that it is possible to produce an iodine-supported organic polymer material in which an iodine compound is supported in an organic polymer material by contacting the iodine compound-containing solution with the organic polymer material for at least 10 seconds.

[0250] <Exemplary Example 10> The amount of the iodine compound supported in the iodine-supported organic polymer material produced by changing the temperature of the iodine compound-containing solution during contact between the organic polymer material having nitrogen atoms and the iodine compound-containing solution was measured. As the organic polymeric materials, the wool fiber woven fabric (Ad) and polyamide fiber woven fabric (Aa) used in "Typical Example 1a", the polyamide fiber nonwoven fabric (Ba) used in "Typical Example 2a", the polyamide film (Ca) used in "Typical Example 3a", and the polyurethane foam (Dba) used in "Typical Example 4a" were used. As the iodine compound-containing solution, the povidone-iodine solution used in "Typical Examples 1a to 4a" was used.

[0251] In the experiment of "Preparation of iodine-supported organic polymer material intermediate material by contacting organic polymer material with iodine compound-containing solution" which is a method similar to "Typical Example 1a to Typical Example 4a", (i) iodine compound-containing solution (200 mL) placed in a glass beaker and cooled to 5°C in a refrigerator, (ii) iodine compound-containing solution (200 mL) placed in a glass beaker and warmed to 30°C in a warming cabinet, and (iii) iodine compound-containing solution (200 mL) placed in a glass beaker and warmed to 40°C in a warming cabinet were prepared, and a specific organic polymer material was immersed in each iodine compound-containing solution for 10 seconds. During the immersion, the iodine compound-containing solution was stirred and the organic polymer material was pressed with tweezers to sufficiently contact the organic polymer material with the iodine compound-containing solution. In this manner, each iodine-supported organic polymer material intermediate material was prepared. Using each of the iodine-supported organic polymer material intermediates thus prepared, each of the iodine-supported organic polymer materials was prepared in a manner similar to that of "Typical Example 1a to Typical Example 4a."

[0252] The amount of iodine supported on each of the iodine-loaded organic polymer materials prepared above was measured by the "iodine back titration" method similar to that of the above-mentioned "Typical Example 1b". For each of the organic polymer materials used, the "amount of iodine supported on the iodine-loaded organic polymer material after contact with the iodine compound-containing solution" measured by "iodine back titration" is shown in Table 10.

[0253] [Table 10]

[0254] In Table 10, when the wool fiber fabric (Ad) was immersed in the iodine compound-containing solutions at the specified temperatures (5° C., 30° C., 40° C.), the amount of iodine supported was almost the same. When the polyamide fiber woven fabric (Aa) was immersed in an iodine compound-containing solution at a predetermined temperature (5° C., 30° C., 40° C.), the amount of iodine supported was almost the same. When the polyamide nonwoven fabric (Ba) was immersed in solutions containing an iodine compound at respective prescribed temperatures (5° C., 30° C., 40° C.), the amount of iodine supported was almost the same. When the polyamide film (Ca) was immersed in an iodine compound-containing solution at a specific temperature (5°C, 30°C, 40°C), the amount of iodine supported was almost the same. When the polyurethane foam (Dba) was immersed in an iodine compound-containing solution at a predetermined temperature (5° C., 30° C., 40° C.), the amount of iodine supported was almost the same.

[0255] That is, the amount of iodine supported was almost the same when the organic polymer material was immersed in an iodine compound-containing solution at 5° C. as when it was immersed in an iodine compound-containing solution at 40° C. From this experimental result, it is understood that it is possible to produce an iodine-supported organic polymer material in which an iodine compound is supported on an organic polymer material by contacting an iodine compound-containing solution and an organic polymer material with an iodine compound-containing solution at 30° C. or less.

[0256] <Typical Example 11> An iodine compound-containing solution was applied to an organic polymer material having nitrogen atoms by showering, thereby producing an iodine-supported organic polymer material containing the iodine compound. The amount of the iodine compound supported in the iodine-supported organic polymer material was measured. As the organic polymer materials, the wool fiber woven fabric (Ad) and polyamide fiber woven fabric (Aa) used in "Typical Example 1a", the polyamide fiber nonwoven fabric (Ba) used in "Typical Example 2a", the polyamide film (Ca) used in "Typical Example 3a", and the polyurethane foam (Dba) used in "Typical Example 4a" were used. As the iodine compound-containing solution, the povidone-iodine solution used in "Typical Examples 1a to 4a" was used.

[0257] In a method similar to "Typical Example 1a to Typical Example 4a", in an experiment of "Preparation of an iodine-supported organic polymer material intermediate by contacting an organic polymer material with an iodine compound-containing solution", At room temperature of about 25°C, a given organic polymer material (4 x 5 cm rectangle) was placed on a stainless steel wire net placed at a height of about 5 cm in a glass beaker with a diameter of 10 cm, with its flat surface facing upward. Separately, an iodine compound-containing solution (200 mL) at about 25°C was prepared in a spray container. The iodine compound-containing solution (200 mL) was sprayed onto the surface of the organic polymer material placed in the beaker for about 10 seconds, so that the iodine compound-containing solution came into contact with the organic polymer material. In this way, each iodine-loaded organic polymer material intermediate was prepared. Using each of the iodine-supported organic polymer material intermediates thus prepared, each of the iodine-supported organic polymer materials was prepared in a manner similar to that of "Typical Example 1a to Typical Example 4a."

[0258] The amount of iodine supported on each of the iodine-loaded organic polymer materials prepared above was measured by the "iodine back titration" method similar to that of the above-mentioned "Typical Example 1b". For each of the organic polymer materials used, the "amount of iodine supported on the iodine-loaded organic polymer material after contact with the iodine compound-containing solution" measured by "iodine back titration" is shown in Table 11.

[0259] [Table 11]

[0260] The amount of iodine supported on each of the organic polymer materials in Table 11 is approximately equal to the amount of iodine supported on the iodine-loaded organic polymer material prepared by immersion deposition shown in Table 8 of the above-mentioned typical example 8. In other words, it can be seen that an iodine-supported organic polymer material produced by showering an iodine compound-containing solution onto an organic polymer material having nitrogen atoms has approximately the same amount of iodine compound supported as an iodine-supported organic polymer material produced by attachment by immersion.

[0261] Exemplary Example 12a In the following experiment, an iodine-loaded organic polymer material was prepared using feathers. (Experiment 12a-a): Feather E: Goose feathers, goose down stuffed in feather duvets manufactured by Nishikawa Co., Ltd. was prepared.

[0262] (Experiment 12a-b): A povidone-iodine solution was prepared as an iodine compound-containing solution by dissolving povidone-iodine in a solvent in the same manner as in the above-mentioned "Typical Example 1-b".

[0263] (Experiment 12a-c): Using a method similar to that of the above-mentioned "Example 1a-c", feathers as an organic polymer material were contacted with a "povidone-iodine solution" to prepare an iodine-loaded organic polymer material intermediate material carrying an iodine compound.

[0264] (Experiments 12a-d): Using a method similar to that of the above-mentioned "Examples 1a-d," the solvent contained in the iodine compound-containing solution was removed from the iodine-loaded organic polymer material intermediate material by washing with water and drying, and then each iodine-loaded organic polymer material was prepared by drying.

[0265] (Experiment 12a-e): Repeated washing / drying experiment of iodine-loaded organic polymer material. Each of the iodine-loaded organic polymer materials prepared by the above "Experiment 12a-d" was placed in 1000 mL of purified water at about 25°C in a beaker, stirred for 5 minutes, and washed. After that, the iodine-loaded organic polymer material was pressed between stainless steel wire mesh to remove moisture. The iodine-loaded organic polymer material was then placed in a breathable bag and placed in a hot air dryer at about 40°C for more than 1 hour to completely remove moisture and dry. In this way, a washed / dried iodine-loaded organic polymer material was prepared. This washing / drying experiment was repeated 10 times.

[0266] (Experiments 12a-f): For the organic polymer materials used, photographs were taken to show the appearance of the organic polymer materials before they were brought into contact with the iodine compound-containing solution, the appearance of the iodine-loaded organic polymer materials obtained in "Experiments 12a-e" after they were washed with water and dried 10 times, and the appearance of the iodine-loaded organic polymer materials obtained in "Experiments 12a-e" after they were stored in a room temperature atmosphere for 15 days. These photographs are shown in Figure 10.

[0267] In FIG. 10, the feathers had a colorless appearance before contacting with the povidone-iodine solution, and the iodine-loaded organic polymer material had a yellow appearance after contacting the feathers with the povidone-iodine solution. In addition, after the iodine compound was supported on the organic polymer material, the iodine-supported organic polymer material was washed with water 10 times and then dried, and the appearance of the iodine-supported organic polymer material maintained its yellow color. Furthermore, the appearance of the iodine-loaded organic polymer material maintained its yellow color after storage in a room temperature atmosphere for 15 days.

[0268] Exemplary Example 12b In the following experiment, an iodine-loaded organic polymer material was prepared using feathers. This example is an iodine-supported organic polymer material prepared by using an "iodine potassium iodide aqueous solution" instead of the povidone-iodine solution as the iodine compound-containing solution in the above "Typical Example 12a".

[0269] (Experiment 12b-a): Feather E (goose feathers, goose down stuffed in duvets manufactured by Nishikawa Co., Ltd.) was prepared.

[0270] (Experiment 12b-b): In the same manner as in "Experiment 5a-b" of the above-mentioned "Typical Example 5a", an iodine-potassium iodide solution was prepared as an iodine compound-containing solution obtained by dissolving iodine and potassium iodide in a solvent. Purified water was added to 79 mL of 0.01 mol / L iodine solution to prepare a total of 200 mL of iodine-potassium iodide solution.

[0271] (Experiment 12b-c): Using a method similar to that of the above-mentioned "Example 1a-c", feathers as an organic polymer material were contacted with an "iodine potassium iodide solution" to prepare an iodine-loaded organic polymer material intermediate material carrying an iodine compound.

[0272] (Experiments 12b-d): Using a method similar to that of the above-mentioned "Examples 1a-d," the solvent contained in the iodine compound-containing solution was removed from the iodine-loaded organic polymer material intermediate material by washing with water and drying, and then each iodine-loaded organic polymer material was prepared by drying.

[0273] (Experiment 12b-e): Repeated washing / drying experiment of iodine-loaded organic polymer material. Each of the iodine-loaded organic polymer materials prepared in the above "Experiments 12b-d" was repeatedly washed and dried in the same manner as in the above "Experiments 12a-e". In this way, the iodine-loaded organic polymer materials after washing and drying were prepared. This washing / drying experiment was repeated 10 times.

[0274] (Experiments 12a-f): Photographs were taken of the appearance of the organic polymer material used before it was brought into contact with the iodine compound-containing solution, the appearance of the iodine-loaded organic polymer material obtained in "Experiments 12b-e" after it was washed with water and dried 10 times, and the appearance of the iodine-loaded organic polymer material after it was stored in a room temperature atmosphere for 15 days. These photographs are shown in Figure 10.

[0275] In FIG. 10, the feathers had a colorless appearance before contacting with the iodine-potassium iodide solution, and the iodine-loaded organic polymer material had a yellow appearance after contacting the feathers with the iodine-potassium iodide solution. In addition, after the iodine compound was supported on the organic polymer material, the iodine-supported organic polymer material was washed with water 10 times and then dried, and the appearance of the iodine-supported organic polymer material maintained its yellow color. Furthermore, the appearance of the iodine-loaded organic polymer material maintained its yellow color after storage in a room temperature atmosphere for 15 days.

[0276] That is, it is understood that in "Typical Example 12a" and "Typical Example 12b", the above-mentioned [Constituent Effect A: Effect of having long-term iodine-loaded durability with iodine compounds prevented from being desorbed for a long period of time: the effect of obtaining an iodine-loaded organic polymer material in which iodine compounds are supported in the organic polymer material for a long period of time by preventing the supported iodine compounds from being desorbed from the iodine-loaded organic polymer material during washing with water and storage in an air atmosphere at room temperature for a long period of time] can be obtained. It is also understood that the above-mentioned [Method effect A: the effect that an iodine-loaded organic polymer material that can be easily produced by a simple and economically advantageous method and has long-term iodine-loading durability in which desorption of iodine compounds is suppressed over a long period of time can be obtained] can be obtained.

[0277] Exemplary Example 13a A commercially available general-purpose polyamide sheet Fa (nylon sheet, 1 mm thick, 4 cm long, 5 cm wide) was used as the organic polymer material, and a 1% povidone-iodine solution prepared by a method similar to that in "Experiment 1a-b" of the above-mentioned "Typical Example 1" was used as the iodine compound-containing solution to prepare a polyamide sheet carrying an iodine compound.

[0278] The polyamide sheet Fa was immersed in a povidone-iodine solution for 10 seconds to prepare an iodine-carrying polyamide sheet intermediate as an iodine-carrying organic polymer material intermediate, and the iodine-carrying polyamide sheet intermediate was dried in a hot air dryer at 30°C for about 5 minutes to remove the moisture in the solvent, thereby preparing an iodine-carrying polyamide sheet as an iodine-carrying organic polymer material. The prepared iodine-carrying polyamide sheet had a yellow color.

[0279] The yellow iodine-supported polyamide sheet was placed in a beaker and washed by running tap water into the beaker for about 1 minute, after which the iodine-supported polyamide sheet was removed from the beaker and dried for about 5 minutes in a hot air dryer at 30° C. This washing / drying process was repeated 10 times. After the repeated washing / drying, the iodine-supported polyamide sheet maintained the same yellow color as before the repeated washing / drying.

[0280] FIG. 11 shows a photograph of the appearance of the polyamide sheet Fa before immersion in the iodine compound-containing solution, and a photograph of the appearance of the iodine-loaded polyamide sheet after repeated washing / drying. In addition, the appearance of the iodine-loaded polyamide sheet after storage at room temperature of 25° C. for 15 days maintained exactly the same yellow color as the iodine-loaded polyamide sheet before storage at room temperature.

[0281] Exemplary Example 13b A commercially available general-purpose polyamide molded block Fb (length 4 cm, width 5 cm, height 1 cm) was used as the organic polymer material, and a 1% povidone-iodine solution prepared by a method similar to "Experiment 1a-b" of the above-mentioned "Typical Example 1" was used as the iodine compound-containing solution to prepare a polyamide molded block carrying an iodine compound.

[0282] Using the polyamide molded block Fb and 1% povidone-iodine solution, an iodine-loaded polyamide molded block loaded with an iodine compound was prepared in a manner similar to that of the above-mentioned "Typical Example 13a". The prepared iodine-loaded polyamide molded block had a yellow color.

[0283] This yellow iodine-carrying polyamide molded block was placed in a beaker and washed by running tap water through the beaker for about 1 minute. Thereafter, the iodine-carrying polyamide molded block was removed from the beaker and dried in a hot air dryer at 30°C for about 5 minutes. This washing / drying was repeated 10 times. After the repeated washing / drying, the iodine-loaded polyamide molded block maintained the same yellow color as before the repeated washing / drying.

[0284] A photograph of the appearance of the blocked polyamide molded product Fb before immersion in the iodine compound-containing solution and a photograph of the appearance of the blocked iodine-loaded polyamide molded product Fb after repeated washing / drying are shown in Fig. 11. In addition, the appearance of the iodine-loaded polyamide sheet after storage at room temperature of 25°C for 15 days maintained exactly the same yellow color as the iodine-loaded polyamide sheet before storage at room temperature.

[0285] That is, it can be seen that in "Exemplary embodiment 13a" and "Exemplary embodiment 13b", the above-mentioned [Configuration effect A] and the above-mentioned [Method effect A] can be obtained.

[0286] <Product Examples> The following describes examples of products in which an iodine-supported organic polymer material, in which an iodine compound is supported on an organic polymer material having nitrogen atoms, is applied to specific products.

[0287] <Product Example 21a> An iodine-loaded organic polymer material loaded with an iodine compound was prepared by the following manufacturing method using a roll of polyamide fiber woven fabric Aa (polyamide fiber woven fabric, manufactured by WAVOU Co., Ltd., SMD-FR30, colorless). (Experiment 21a-a): A polyamide fiber woven fabric (WAVOU Co., Ltd., SMD-FR30, width 110 cm, length 5 m, colorless) was lightly folded to prepare an organic polymer material with a width of 27.5 cm and a length of 25 cm. Three pieces of this polyamide fiber woven fabric were prepared.

[0288] (Experiment 21a-c): An iodine compound-containing solution (1% povidone-iodine aqueous solution) was prepared in the same manner as in "Experiment 1a-b" of the above-mentioned "Typical Example 1a." 20 L of an iodine compound-containing solution (1% povidone-iodine aqueous solution) was placed in a 22 L polyethylene container, and the above two sheets of organic polymer material (lightly folded polyamide fiber woven fabric) were immersed in the iodine compound-containing solution for 3 minutes while moving them up and down and left and right. In this way, an iodine-loaded organic polymer material intermediate was prepared.

[0289] (Experiment 21a-d): Preparation of iodine-loaded organic polymer material by removing the solvent from the iodine-loaded organic polymer material intermediate. The iodine-carrying organic polymer intermediate material was removed from the iodine compound-containing solution and placed in a 22 L polyethylene container. 20 L of purified water at about 25°C was added to the polyethylene container and stirred for 5 minutes to wash the iodine-carrying organic polymer intermediate material. Thereafter, the iodine-carrying organic polymer intermediate material was pressed between stainless steel wire mesh to remove moisture. Thereafter, the intermediate material of the iodine-loaded organic polymer material was placed on a wire net in a hot air dryer at about 30° C. for 24 hours or more to completely remove moisture and dry it. In this manner, a polyamide fiber woven fabric loaded with an iodine compound and having a long roll shape with a width of 110 cm and a length of 5 m was prepared as the iodine-loaded organic polymer material.

[0290] The polyamide fiber woven fabric prepared in this manner had the same yellow color as the iodine compound-supported polymer material (Aa: polyamide fiber woven fabric) in Fig. 1. In other words, the yellow color of the polyamide fiber woven fabric prepared in this manner indicates that it is an iodine-supported organic polymer material (iodine-supported polyamide fiber woven fabric) that supports an iodine compound.

[0291] <Product Example 21ab> Using two pieces of iodine-loaded polyamide fiber fabric having a width of 110 cm and a length of 5 m prepared according to the above Product Example 21a, a gown, pants, and a hat for medical staff were prepared by sewing. The prepared medical gowns, trousers and hats were yellow in colour, indicating that they contained iodine compounds.

[0292] <Product Example 21abc> The long roll of iodine compound-supported fabric prepared by "Product Example 21a" and the gown, trousers and hat prepared by "Product Example 21ab" were washed in a 22 L polyethylene container with running tap water for 3 minutes, then dehydrated by a rotary centrifugal spin-drying machine, and then dried by blowing air at room temperature with an electric fan. This washing and drying process was repeated five times. The long roll of cloth, gown, trousers, and hat carrying the iodine compound maintained the same yellow color as before washing even after such washing, that is, it was confirmed that the gown, trousers, and hat carrying the iodine compound maintained the state of carrying the iodine compound even after washing.

[0293] The long rolls of fabric carrying the prepared iodine compounds, as well as the gown, trousers, and hat, maintained the same yellow color as before storage even when stored for 15 days in a room temperature atmosphere at a temperature of 20 to 35°C and a relative humidity of 40 to 90% RH. In other words, it was confirmed that the gown, trousers, and hat carrying the iodine compounds maintained the state of carrying the iodine compounds even after long-term storage at room temperature.

[0294] <Product Example 21b> A gown, trousers, and hat were sewn using the same polyamide fiber fabric (WAVOU Corporation, SMD-FR30, colorless) as in "Product Example 21a" above, and an "iodine-potassium iodide solution" prepared in the same manner as in "Experiment 5a-b" of "Typical Example 5a" above was used instead of the "1% povidone-iodine aqueous solution" as the iodine compound-containing solution, to prepare an iodine-loaded organic polymer material (iodine-loaded polyamide fiber fabric) in the form of a gown, trousers, and hat in a manner similar to that of "Product Example 21a" above. The medical gowns, trousers and hats prepared in this manner were brown in colour, indicating that they contained iodine compounds.

[0295] The gown, trousers, and hat thus prepared were washed and dried five times in the same manner as in Example 21a. It was confirmed that the gown, trousers, and hat carrying the iodine compound maintained the same brown color as before washing even after washing, and maintained the state in which the iodine compound was carried even after washing.

[0296] The products carrying the iodine compounds thus prepared maintained the same brown color as before storage even when stored for 15 days in a room temperature atmosphere at a temperature of 20 to 35°C and a relative humidity of 40 to 90% RH. In other words, it was confirmed that the gowns, trousers, and hats carrying the iodine compounds maintained the state in which the iodine compounds were carried even after long-term storage at room temperature.

[0297] <Product Example 21c> (Experiment 21c-a): Using the same polyamide fiber fabric (WAVOU Corporation, SMD-FR30, colorless) as in "Product Example 21a" above, a gown, pants, and a hat for medical staff were prepared as organic polymer materials by sewing. (Experiment 21c-c): An iodine compound-containing solution (1% povidone-iodine aqueous solution) was prepared in the same manner as in "Experiment 1a-b" of the above-mentioned "Typical Example 1a." 20 L of an iodine compound-containing solution (1% povidone-iodine aqueous solution) was placed in a 22 L polyethylene container, and the organic polymer materials (gown, trousers, hat) were immersed in the iodine compound-containing solution for 3 minutes while moving them up and down and left and right. In this way, an iodine-containing gown intermediate material, an iodine-containing trouser intermediate material, and an iodine-containing hat intermediate material were prepared as iodine-containing organic polymer material intermediate materials.

[0298] (Experiment 21c-d): Iodine-carrying organic polymer material intermediates (iodine-carrying gown intermediate, iodine-carrying trouser intermediate, and iodine-carrying hat intermediate) were removed from the iodine compound-containing solution, and the removed iodine-carrying organic polymer material intermediates were placed in a 22 L polyethylene container, and 20 L of purified water at approximately 25°C was added to the polyethylene container, stirred for 5 minutes, and washed, and then the iodine-carrying organic polymer material intermediates were pressed between stainless steel wire mesh to remove moisture. Thereafter, the iodine-loaded organic polymer intermediate material was placed on a wire net in a hot air dryer at about 30° C. for 24 hours or more to completely remove moisture and dry it. In this manner, polyamide fiber woven fabrics loaded with iodine compounds (iodine-loaded gown, iodine-loaded trousers, and iodine-loaded hat) were prepared.

[0299] The polyamide fiber woven fabric thus prepared had the same yellow color as the iodine compound-supported polymer material in FIG. 1 (Aa: polyamide fiber woven fabric). In other words, the polyamide fiber fabrics prepared in this manner (iodine-loaded gown, iodine-loaded trousers, and iodine-loaded hat) have a yellow color, and therefore are understood to be iodine-loaded organic polymer materials (iodine-loaded polyamide fiber fabrics) that load iodine compounds.

[0300] The iodine-loaded organic polymer materials thus prepared (iodine-loaded gown, iodine-loaded trousers, and iodine-loaded hat) were placed in a 22 L polyethylene container, washed with running tap water for 3 minutes, then dehydrated by a rotary centrifugal spin-drying machine, and then dried by blowing air with a fan at room temperature. This washing and drying process was repeated five times. The iodine-loaded organic polymer materials carrying iodine compounds maintained the same yellow color as before cleaning even after such cleaning. In other words, it was confirmed that the iodine-loaded organic polymer materials carrying iodine compounds (iodine-loaded gown, iodine-loaded trousers, and iodine-loaded hat) maintained the state of carrying iodine compounds even after cleaning.

[0301] The products carrying the iodine compounds thus prepared maintained the same yellow color as before storage even when stored for 15 days in a room temperature atmosphere at a temperature of 20 to 35°C and a relative humidity of 40 to 90% RH. In other words, it was confirmed that the gowns, trousers, and hats carrying the iodine compounds maintained the state in which the iodine compounds were carried even after long-term storage at room temperature.

[0302] <Product Example 21d> A gown, trousers, and hat were sewn using the same polyamide fiber fabric (WAVOU Corporation, SMD-FR30, colorless) as in "Product Example 21a" above, and an "iodine-potassium iodide solution" prepared in the same manner as in "Experiment 5a-b" of "Typical Example 5a" above was used instead of the "1% povidone-iodine aqueous solution" as the iodine compound-containing solution, to prepare an iodine-loaded organic polymer material (iodine-loaded polyamide fiber fabric) in the form of a gown, trousers, and hat in a manner similar to that of "Product Example 21c" above. The medical gowns, trousers and hats prepared in this manner were brown in colour, indicating that they contained iodine compounds.

[0303] The gown, trousers, and hat thus prepared were washed and dried five times in the same manner as in Example 21a. It was confirmed that the gown, trousers, and hat carrying the iodine compound maintained the same brown color as before washing even after washing, and maintained the state in which the iodine compound was carried even after washing.

[0304] The products carrying the iodine compounds thus prepared maintained the same brown color as before storage even when stored for 15 days in a room temperature atmosphere at a temperature of 20 to 35°C and a relative humidity of 40 to 90% RH. In other words, it was confirmed that the gowns, trousers, and hats carrying the iodine compounds maintained the state in which the iodine compounds were carried even after long-term storage at room temperature.

[0305] <Product Example 21e> Using the same rolls of polyamide fiber fabric Aa (polyamide fiber fabric, manufactured by WAVOU Co., Ltd., SMD-FR30, colorless) as in "Product Example 21a" above, gowns, trousers and hats for medical staff were prepared by sewing. Thereafter, at room temperature, an iodine compound-containing solution (1% povidone-iodine aqueous solution) prepared in the same manner as in "Experiment 1a-b" of "Typical Example 1a" above was sprayed onto the entire surfaces of the gown, trousers and hat while still attached to the hanger. After about 5 minutes had passed, the gown, trousers and hat were placed in a warm air dryer at 30° C. to remove moisture and dry them. In this way, a gown, pants, and hat carrying a yellow iodine compound were prepared. The gown, trousers and hat prepared in this manner were yellow in colour, indicating that they were products carrying an iodine compound.

[0306] The gown, trousers, and hat thus prepared were washed and dried five times in the same manner as in the above-mentioned Product Example 21a. It was confirmed that the gown, trousers, and hat carrying the iodine compound maintained the same yellow color as before washing even after washing, and maintained the state in which the iodine compound was carried even after washing.

[0307] The products carrying the iodine compounds thus prepared maintained the same yellow color as before storage even when stored for 15 days in a room temperature atmosphere at a temperature of 20 to 35°C and a relative humidity of 40 to 90% RH. In other words, it was confirmed that the gowns, trousers, and hats carrying the iodine compounds maintained the state in which the iodine compounds were carried even after long-term storage at room temperature.

[0308] <Product Example 22a> A long polyamide film Ca (Sevix YON, YON-25, colorless, 25 μm thick, 50 cm wide, 200 cm long, colorless, manufactured by Unitika Ltd.) was prepared. A portion of a commercially available 4000 m long Sevix YON manufactured by Unitika Ltd. was cut out and used.

[0309] An iodine compound-containing solution (1% povidone-iodine aqueous solution) was prepared in the same manner as in "Experiment 1a-b" of the above-mentioned "Typical Example 1a." The iodine compound-containing solution was held in a polyethylene sponge material. At room temperature of 25°C, the entire front and back surfaces of the polyamide film were contacted with a polyethylene sponge material holding an iodine compound-containing solution (1% povidone-iodine aqueous solution) to prepare an iodine-loaded organic polymer material intermediate for the polyamide film. After about 5 minutes had elapsed, the long polyamide film was dried at room temperature of about 25° C. by applying air from an electric fan to remove moisture. In this way, a long polyamide film carrying an iodine compound having a yellow color was prepared. The long polyamide film thus prepared is yellow in color, and therefore it is understood to be a polymer material carrying an iodine compound.

[0310] <Product Example 22ab> A portion of the long polyamide film carrying the iodine compound prepared in "Product Example 22a" was used to prepare a gown and disposable gloves for medical staff by using an adhesive. The medical gowns and disposable gloves prepared in this manner are yellow in color, indicating that they contain an iodine compound.

[0311] <Product Example 22abc> A portion of the long polyamide film prepared according to "Product Example 22a" and a gown and disposable gloves prepared according to "Product Example 22ab" were washed and dried five times in the same manner as in Product Example 21a. It was confirmed that the gown and disposable gloves carrying the iodine compound maintained the same yellow color as before washing even after washing, and maintained the state in which the iodine compound was carried even after washing.
