Mode for Carrying Out the Invention
[0013] The quaternary ammonium ion is a monovalent cation in which four carbon bonds are directly bonded to a nitrogen atom, and is known to have antibacterial and antiviral properties. It is said that the strength of antibacterial and antiviral properties, and the antibacterial spectrum and antiviral spectrum vary depending on the group bonded to the nitrogen atom. In addition, it has been found that the antibacterial spectrum and antiviral spectrum also differ depending on the type of counter ion of the quaternary ammonium ion. It is considered that this is because the degree of ionic dissociation of the quaternary ammonium salt changes according to the type of the counter ion, and the activity against the membranes of bacteria and viruses is different.
[0014] In the present embodiment, at least two types of quaternary ammonium salts are used. Thereby, the antibacterial spectrum and the antiviral spectrum can be broadened. Further, a metal salt is used in combination with at least two types of quaternary ammonium salts. In addition to exhibiting strong cationicity, metal ions have a small ionic radius, so they act strongly on the membranes of bacteria and viruses. As a result, the potential on the membrane surface changes, the cationicity increases, and an electrical repulsion occurs. Therefore, it is considered that the distance between the proteins constituting the membrane widens, the nucleus is exposed, and bacteria and viruses are easily destroyed.
[0015] In addition, in this embodiment where a metal salt is used in combination with at least two types of quaternary ammonium salts, the metal salt is used such that its content becomes excessive compared to the total content of the quaternary ammonium salts. Generally, it is said that quaternary ammonium salts act on enveloped viruses, but have almost no antiviral property against non-enveloped viruses. By adding an excessive amount of the metal salt, antiviral property is exhibited even against non-enveloped viruses. Thereby, it is considered that the antibacterial spectrum and the antiviral spectrum are further broadened.
[0016] [Processing agent] The processing agent according to this embodiment contains a specific metal salt and at least two types of quaternary ammonium salts. This processing agent has a broad antibacterial spectrum and antiviral spectrum, and high antibacterial and antiviral properties. Therefore, the processing agent according to this embodiment can function as an "antibacterial processing agent", function as an "antiviral processing agent", and function as an "antibacterial and antiviral processing agent". In particular, the processing agent according to this embodiment is useful as an "antiviral processing agent".
[0017] The processing agent is preferably aqueous, and more preferably an aqueous solution. Being aqueous means that each component is present in an aqueous medium. At this time, each component may be dissolved in the aqueous medium or dispersed in the aqueous medium. Examples of the aqueous medium include pure water, distilled water, ion-exchanged water, and tap water. The processing agent may contain an organic solvent as necessary.
[0018] The metal salt is formed from at least one metal ion selected from the group consisting of Fe (iron), Co (cobalt), Ni (nickel), Cu (copper), Zn (zinc), Pt (platinum), Ag (silver) and Au (gold), and at least one anion selected from the group consisting of chloride ion, bromide ion, fluoride ion, iodide ion, sulfate ion, hydroxide ion, nitrate ion and acetate ion. The quaternary ammonium salt contains a first quaternary ammonium salt and a second quaternary ammonium salt different from the first quaternary ammonium salt.
[0019] The ratio of the content mass M of the metal salt to the total content mass A of the quaternary ammonium salt: M / A is from 20 / 1 to 1.2 / 1. When the content mass M of the metal salt is in excess of the total content mass A of the quaternary ammonium salt, the antibacterial spectrum and the antiviral spectrum are further broadened. The ratio: M / A is preferably from 17.5 / 1 to 1.6 / 1, and particularly preferably from 15 / 1 to 2 / 1.
[0020] (Quaternary ammonium salt) The quaternary ammonium salt is a salt of a quaternary ammonium ion and its counter ion (anion). The quaternary ammonium salt contains at least a first quaternary ammonium salt and a second quaternary ammonium salt. The first quaternary ammonium salt is a salt of a first quaternary ammonium ion and a first counter ion. The second quaternary ammonium salt is a salt of a second quaternary ammonium ion and a second counter ion.
[0021] The first quaternary ammonium salt and the second quaternary ammonium salt are different compounds. The first and second quaternary ammonium salts differ in the groups bonded to the nitrogen atoms of the first and second quaternary ammonium ions and / or the first and second counter ions are different. Among them, it is preferable that at least the first and second counter ions are different in terms of easily obtaining a broad antibacterial spectrum and antiviral spectrum while maintaining high antibacterial and antiviral properties.
[0022] Examples of the first and second counter ions include chloride ion, bromide ion, fluoride ion, iodide ion, hydroxide ion, phosphate ion, nitrate ion, sulfate ion, and other molecular ions (polyatomic ions).
[0023] Among them, from the viewpoint of antibacterial property, it is preferable that the first counter ion is chloride ion and the second counter ion is phosphate ion. That is, it is preferable that the first quaternary ammonium salt is ammonium chloride and the second quaternary ammonium salt is ammonium phosphate. Ammonium chloride is known to have the highest bactericidal activity among quaternary ammonium salts. On the other hand, excessive ammonium chloride may corrode metals. By using ammonium phosphate together with ammonium chloride, it becomes easier to suppress the influence on metals while maintaining high antibacterial property.
[0024] In terms of the antibacterial spectrum and antiviral spectrum being more likely to be broadened, the ratio of the mass content A1 of ammonium chloride to the mass content A2 of ammonium phosphate: A1 / A2 is preferably from 1 / 20 to 20 / 1. The ratio: A1 / A2 is more preferably from 1 / 15 to 15 / 1, still more preferably from 1 / 10 to 10 / 1, and particularly preferably from 1 / 10 to 1 / 1. Further considering the stability of the processing agent, the ratio: A1 / A2 is preferably from 1 / 20 to 1 / 1.2, more preferably from 1 / 15 to 1 / 1.6, and particularly preferably from 1 / 10 to 1 / 2. When the ratio: A1 / A2 is within the above range, the pH of the processing agent is less likely to fluctuate due to the buffering action of phosphate ions, and the stability of the processing agent is improved. When the stability of the processing agent is high, the ammonium cation is more likely to adsorb to the proteins of bacteria and viruses. As a result, the effect of the processing agent is more likely to be exerted.
[0025] The structures of the first and second quaternary ammonium ions are not particularly limited. From the viewpoints of antibacterial property and antiviral property, at least one of the first quaternary ammonium ion and the second quaternary ammonium ion is represented by the following formula (I):
[0026] [Chemical formula] (In formula (I), R1 and R3 are each independently an alkyl group having 1 to 6 carbon atoms, a hydroxyalkyl group having 1 to 4 carbon atoms, or an alkylene oxide group having 1 to 4 carbon atoms, and R2 and R4 are each independently a hydrocarbon group having 6 to 20 carbon atoms.) Preferably, it is represented by the following formula. Among them, it is preferable that both the first quaternary ammonium ion and the second quaternary ammonium ion are represented by the above formula (I). The groups bonded to the nitrogen atoms of the first and second quaternary ammonium ions may all be the same, some may be the same, or all may be different.

Specific examples of R1 and R3 which are hydroxyalkyl groups having 1 to 4 carbon atoms include, each independently, a hydroxymethyl group, a hydroxyethyl group, a hydroxy n-propyl group, a hydroxyisopropyl group, a hydroxy n-butyl group, and the like. Specific examples of R1 and R3 which are alkylene oxide groups having 1 to 4 carbon atoms include, each independently, an ethylene oxide group, a propylene oxide group, a butylene oxide group, and the like. Among them, from the viewpoints of antibacterial property and antiviral property, R1 and R3 are each independently preferably an alkyl group having 1 to 6 carbon atoms, more preferably an alkyl group having 1 to 4 carbon atoms, and particularly preferably both are methyl groups.
[0028] R2 and R4 are each independently a hydrocarbon group having 6 to 20 carbon atoms, which may have an aromatic ring and / or a substituent. Specifically, as R2 and R4, each independently, a linear alkyl group having 6 to 20 carbon atoms, a branched alkyl group having 6 to 20 carbon atoms, a hydrocarbon group having one or more carbon-carbon double bonds having 6 to 20 carbon atoms, a phenyl group, a benzyl group, etc. may be mentioned. Examples of the substituent that R2 and R4 may have include a hydroxy group, a carbonyl group, etc. Among them, from the viewpoints of antibacterial and antiviral properties, R2 is preferably a hydrocarbon group having 6 to 20 carbon atoms having one or more aromatic rings, and may be a benzyl group. From the same viewpoints, R4 is preferably an alkyl group having 8 to 18 carbon atoms, may be a linear alkyl group having 8 to 18 carbon atoms, and may be a linear alkyl group having 12 to 16 carbon atoms.
[0029] In particular, in the first quaternary ammonium ion, it is preferable that both R1 and R3 are methyl groups, R2 is a benzyl group, and R4 is a linear alkyl group having 12 to 16 carbon atoms. In the second quaternary ammonium ion, it is preferable that both R1 and R3 are methyl groups, R2 is a benzyl group, and R4 is a linear alkyl group having 8 to 18 carbon atoms or. In this case, the quaternary ammonium ion has a benzalkonium skeleton and an appropriate long-chain alkyl group. Therefore, the antibacterial and antiviral properties are further improved. Such a quaternary ammonium ion is also preferable in terms of production cost, etc.
[0030] The processing agent may contain a quaternary ammonium salt formed from quaternary ammonium ions other than those represented by the above formula (I), and a quaternary ammonium salt formed from counterions other than chloride ions and phosphate ions (hereinafter collectively referred to as other quaternary ammonium salts).

[0032] The total concentration of the quaternary ammonium salt is not particularly limited and may be appropriately set in consideration of the viscosity of the processing agent, the method of attaching the processing agent to the article to be processed, the use of the processed article, etc. From the viewpoints of easy preparation, excellent stability and handleability, the total concentration of the quaternary ammonium salt in the processing agent is preferably 0.005% by mass or more, more preferably 0.01% by mass or more, further preferably 0.05% by mass or more, particularly preferably 0.075% by mass or more, and most preferably 0.1% by mass or more.

When the processing agent is attached to the article to be treated by an impregnation method, for example, it is used after diluting the processing agent with an aqueous medium. The dilution ratio is not particularly limited and is appropriately set according to the form and material of the article to be treated. The dilution ratio is preferably 1000 times or less.
[0034] The source of the quaternary ammonium salt is not particularly limited. The source of the quaternary ammonium salt may be contained in, for example, a commercially available processing agent or treatment agent for other uses (for example, dye fixing).
[0035] (Metal salt) The metal salt (hereinafter sometimes referred to as the first metal salt) is composed of at least one metal ion selected from the group consisting of Fe (iron), Co (cobalt), Ni (nickel), Cu (copper), Zn (zinc), Pt (platinum), Ag (silver) and Au (gold), and at least one anion selected from the group consisting of chloride ion, bromide ion, fluoride ion, iodide ion, sulfate ion, hydroxide ion, nitrate ion and acetate ion. The first metal salt is used alone or in combination of two or more. The first metal salt may be added to the processing agent as a hydrate. Among them, from the viewpoints of antibacterial and antiviral properties, copper, zinc and silver are preferable, and copper is more preferable.
[0036] The counter ion (anion) of the metal ion is at least one selected from the group consisting of chloride ion, bromide ion, fluoride ion, iodide ion, sulfate ion, hydroxide ion, nitrate ion and acetate ion. Among them, from the viewpoints of production cost and the like, at least one selected from the group consisting of sulfate ion, hydroxide ion, nitrate ion and acetate ion which are polyatomic ions is preferable, and at least one selected from the group consisting of sulfate ion, nitrate ion and acetate ion is more preferable.
[0037] As the first metal salt, at least one selected from the group consisting of copper sulfate, copper chloride, copper acetate, zinc sulfate, zinc nitrate, zinc acetate, iron sulfate and silver nitrate is preferably exemplified.

[0040] The concentration of the first metal salt is not particularly limited and may be appropriately set in consideration of the viscosity of the processing agent, the method of attaching the processing agent to the article to be processed, the use of the processed article, etc. From the viewpoints of easy preparation, excellent stability and handleability, the concentration of the first metal salt in the processing agent is preferably 0.06% by mass or more, more preferably 0.09% by mass or more, further preferably 0.12% by mass or more, and particularly preferably 0.5% by mass or more.

Examples of the other components include a softening agent for improving the texture of the article to be treated, a dye fixing agent, an antistatic agent, and a water repellent. The other components are preferably those that are difficult to destabilize the metal ions generated by the dissociation of the first metal salt or those that are difficult to form a chelate with the metal ions, and more preferably those that do not form a chelate with the metal ions.
[0043] [Treatment agent] The treatment agent according to the present embodiment contains the above-described processing agent and a binder resin. As a result, the first metal salt and the two kinds of quaternary ammonium salts are fixed to the article to be treated via the binder resin, so that antibacterial and antiviral properties are likely to be exhibited over a long period of time. "Fixation" means being more firmly attached than "adhesion". The treatment agent according to the present embodiment can function as an "antibacterial treatment agent", can function as an "antiviral treatment agent", and can function as an "antibacterial and antiviral treatment agent". In particular, the treatment agent according to the present embodiment is useful as an "antiviral treatment agent".
[0044] (Binder resin) The binder resin is not particularly limited, and examples thereof include an acrylic resin, polyvinyl alcohol, an ethylene-vinyl acetate resin, a polyurethane resin, a polyamide resin, a polyester resin, a silicone resin, and a fluororesin.
[0045] The blending amount of the binder resin is not particularly limited, and may be, for example, 1% by mass or more and 50% by mass or less of the treatment agent. The binder resin may be contained in any form. For example, a commercially available agent containing the binder resin may be mixed with a processing agent containing the first metal salt, the two kinds of quaternary ammonium salts, an aqueous medium, and the like.
[0046] [Processed article] The processed article according to this embodiment includes a workpiece, a metal salt adhering to the workpiece, and two or more kinds of quaternary ammonium salts.

The metal salt, two or more kinds of quaternary ammonium salts, and the binder resin are derived from the above treatment agent. These processed articles also have a broad antibacterial spectrum and antiviral spectrum, and high antibacterial and antiviral properties.
[0047] When using the above treatment agent, the metal salt (first metal salt) and two or more kinds of quaternary ammonium salts are adhered (fixed) to the workpiece via the binder resin.
[0048] The adhesion amount of the first metal salt and two or more kinds of quaternary ammonium salts is not particularly limited and may be appropriately set according to the usage form of the processed article and the like. In terms of being likely to exhibit antibacterial and antiviral properties, the total adhesion amount (mass) of the metal salt and two or more kinds of quaternary ammonium salts is preferably 0.01% or more, more preferably 0.025% or more, and particularly preferably 0.04% or more of the mass of the workpiece. From the perspective of cost and the like, the total adhesion amount of the metal salt and two or more kinds of quaternary ammonium salts may be 8% or less, 5% or less, or 2% or less of the mass of the workpiece. The preferable adhesion amount of the metal salt and two or more kinds of quaternary ammonium salts is 0.01% or more and 8% or less of the mass of the workpiece.
[0049] (Workpiece) The article to be processed is not particularly limited. The article to be processed includes, for example, at least one selected from the group consisting of natural fibers, regenerated fibers, semi-synthetic fibers, and synthetic fibers. Natural fibers are roughly classified into plant fibers and animal fibers. Examples of plant fibers include cotton, hemp, pulp, etc. Examples of animal fibers include feathers, silk, animal hair (wool, angora, cashmere, mohair, camel hair, rabbit hair, horse hair, llama hair), etc. Examples of regenerated fibers include rayon, polynosic, cupra, solvent-spun cellulose fibers, etc. Examples of semi-synthetic fibers include acetate, triacetate, etc. Examples of synthetic fibers include polyester, polyolefin, polyamide, polyurethane, acrylic, etc.
[0050] The article to be processed may contain animal fibers, particularly animal hair, and more particularly wool. When the article to be processed contains animal fibers, it is difficult for the antibacterial and antiviral properties of the processed article to decrease. That is, it exhibits excellent durability. The processed article containing animal fibers has, for example, high washing durability. The processed article containing animal fibers exhibits high washing durability even when, for example, no binder resin is used. The reason for this is not clear, but it is considered that the side chains of amino acids constituting the protein contained in animal fibers are ionically bonded to the metal ions or quaternary ammonium ions contained in the processing agent or treatment agent.
[0051] Animal hair (particularly wool) is easy to make into yarn and easy to form into fabrics (woven fabrics, knitted fabrics, non-woven fabrics) among animal fibers. Since the processing agent or treatment agent can be easily fixed on the surface of the fabric, antibacterial and antiviral properties are easily exhibited, and durability is also easily improved.
[0052] The mass ratio of the animal fiber in the article to be processed may be 10% by mass or more, may be 20% by mass or more, and may be 30% by mass or more. In one aspect, the mass ratio of the animal fiber in the article to be processed is 10% by mass or more and 100% by mass or less.
[0053] The mass ratio in the processed article of wool may be 10% by mass or more, may be 20% by mass or more, and may be 30% by mass or more. In one aspect, the mass ratio in the processed article of wool is 10% by mass or more and 100% by mass or less.
[0054] The processed article may be the fiber itself, may be a yarn obtained by twisting at least one of the above fibers, or may be a fiber structure formed by the above fiber or yarn.
[0055] The yarn may be a monofilament yarn, a multifilament yarn, or a spun yarn. The fiber or its yarn can be used, for example, as a filling for pillows, futons, jackets, coats, etc. The fineness and length of the fiber or yarn are not particularly limited and are appropriately set according to the application, etc.
[0056] Examples of the fiber structure include woven fabrics, knitted fabrics, non-woven fabrics, and granulated cotton (also called ball-shaped cotton or granular cotton) in which fibers or yarns are aggregated in a granular form. As described above, in terms of being likely to exhibit antibacterial and antiviral properties and being likely to improve durability, the fiber structure may be a fabric such as a woven fabric, a knitted fabric, or a non-woven fabric. The fiber structure is used, for example, as bedding supplies such as futon covers, bed sheets, and pillow covers, bedding fillings, nightgowns (pajamas), outerwear, underwear, sweaters, cut shirts, suits, school uniforms, etc. for general clothing, clothing fillings, curtains, carpets, wallpapers, tablecloths, etc. for interior decoration supplies, hand towels, bath towels, foot wiping mats, etc. for bathroom supplies, and sanitary materials such as anti-infection masks, gauze, and bandages.
[0057] Specific examples of the processed article will be described. As the processed article, non-woven fabric is suitable for disposable applications. The form of the non-woven fabric is not particularly limited, and examples include short fiber non-woven fabric, long fiber non-woven fabric, and laminates thereof. In particular, from the viewpoints of preventing penetration of the treatment agent and preventing processing troubles, the basis weight (mass per unit area) of the non-woven fabric is preferably 10 g / m 2 or more, and preferably 15 g / m 2The above is particularly preferred. In the case of disposable applications, from the viewpoints of cost, handleability, etc., the basis weight of the nonwoven fabric is 150 g / m 2 or less is preferred, and 100 g / m 2 or less is particularly preferred. The type of nonwoven fabric is not particularly limited. Examples of the type of nonwoven fabric include thermal bonded nonwoven fabrics (such as air-through nonwoven fabrics, embossed nonwoven fabrics, etc.), needle punched nonwoven fabrics, hydroentangled nonwoven fabrics, spunbond nonwoven fabrics, meltblown nonwoven fabrics, and the like. In particular, when applying a processing agent or a treatment agent by the coating method described later, from the viewpoints of production process and adhesiveness, thermal bonded nonwoven fabrics and spunbond nonwoven fabrics are preferred.
[0058] [Method for manufacturing a processed article] The processed article according to the present embodiment is manufactured, for example, by a method including a step of bringing the above-described processing agent or treatment agent into contact with the above-described article to be processed.
[0059] When the article to be processed is a fiber, yarn, sliver or top, after the contacting step, a fibrous structure may be formed using this fiber, yarn, sliver or top. The article to be processed may be a fibrous structure before cutting, or a fibrous structure after cutting and sewing.
