Description

  The present invention relates to a mask worn on a wearer's face, and more particularly to a mask having an antibacterial action.

  Masks are widely used to prevent germs, dust, and the like from entering the body with respiration, and to prevent secretions from the mouth and nose from scattering around. In recent years, many products have been proposed because they are also effective in preventing hay fever. For example, using a stretchable sheet such as a nonwoven fabric, a mask (for example, see Patent Literature 1) in which a cover portion covering the mouth and an ear hook portion extending rearward from the cover portion are integrally formed, or a rectangular shape A fold that is provided by folding along the long side of the mask body so as to secure a breathing space between the mask body and the face (for example, see Patent Document 2) Etc. are known.

(First Embodiment)
FIG. 1 shows a configuration of a mask 10 according to a first embodiment of the present invention. The mask 10 includes, for example, a main body 11 that covers at least the mouth, and ear hooks 12 provided on both left and right sides of the main body 11. The main body 11 has, for example, a pleated structure that can expand outward. The ear hook portion 12 is made of, for example, a stretch-like cord-like member.

（式１において、Ｒ１、Ｒ２、Ｒ３及びＲ４は、それぞれ同一又は異なっても良い、水素又は炭素数が１〜４のアルキル基である。また、ｎは２〜１０である。） FIG. 2 illustrates a cross-sectional configuration of the main body 11. The main body 11 is coated with an antimicrobial member 11A containing an antimicrobial agent and a silane-based coating liquid formed on the surface of the antimicrobial member 11A and containing a compound represented by Formula 1 as a main component, and cured by the action of a catalyst. And a solidified coating film 11B.

(In the formula 1, R1, R2, R3 and R4 may be the same or different and each is hydrogen or an alkyl group having 1 to 4 carbon atoms, and n is 2 to 10.)

  As the antibacterial member 11A, for example, a material in which an antibacterial agent is contained in a base material made of a fiber material is preferable. Typical examples of the substrate include a cloth material such as a nonwoven fabric and a cloth (for example, gauze), and a paper material such as Japanese paper and Western paper.

  Antibacterial agents include, for example, indigo, indigo extract, tryptanthrin, rush, rush extract, chlorogenic acid, kumasasa, kumasasa extract, diethyl ether, mugwort, mugwort extract, Zioner, Shiso, Shiso Extract, perylaldehyde, luteolin, light load, light load extract, olive leaf, olive leaf extract, oleuropein, kuromoji, kuromoji extract, linalool, geraniol, hinoki, hinoki extract, hinokitiol, hiba , Hiba extract, cedar, cedar extract, fir, fir extract, bamboo, bamboo extract, sansho, sansho extract, mulberry, mulberry extract, oregano, oregano extract, carvacrol , Tea tree, tea tree extract, terpinen 4-ol, cinnamon, cinnamon extract, cinnamon aldehyde, cinnamon leaf, cinnamo Leaf extract, clove, clove extract, eugenol, rosemary, rosemary extract, rosmarinic acid, eucalyptus, eucalyptus extract, cineole, mint, mint extract, menthol, lavender, lavender extract , Echinacea, Echinacea extract, Lemongrass, Lemongrass extract, Citral, Thyme, Thyme extract, Peppermint, Peppermint extract, Lemon Myrtle, Lemon Myrtle extract, Ravensala, Ravensala extract, Sage, Sage , An extract of winter savory, and an extract of winter savory. This is because they have antibacterial properties and are highly safe because they are plant-derived substances. In addition, some of them have aromatic properties and can be used comfortably.

  Antibacterial agents include, for example, indigo, rush, kumasasa, mugwort, perilla, light load, olive leaf, kuromoji, hinoki, hiba, cedar, fir, bamboo, pepper, mulberry, oregano, tea tree, cinnamon, cinnamon leaf, clove, Rosemary, eucalyptus, mint, lavender, echinacea, lemongrass, thyme, peppermint, lemon myrtle, lavensala, sage, or winter savory may be contained in the base material in powder form, and extracts thereof, for example, These essential oils and extracts may be contained in the base material. Furthermore, the components contained therein, for example, tryptanthrin which is a component contained in indigo, chlorogenic acid which is a component contained in rush, diethyl ether which is a component contained in Kumusasa, sionell which is a component contained in mugwort, and Shiso Perylaldehyde or Luteolin, a component contained in mint, menthol, a component contained in mint or mint, oleuropein, a component contained in olive leaves, linalool or geraniol, a component contained in kuromoji, contained in Hinoki or Hiba Hinokitiol, carvacrol, a component contained in oregano, terpinen 4-ol, a component contained in tea tree, cinnamonaldehyde, a component contained in cinnamon, eugenol, a component contained in clove, rosemary Rosmarinic acid, which is a component contained in, cineol a component contained in eucalyptus or lavender, or citral may be contained in the base material is a component contained in lemongrass.

  The coat film 11B is formed, for example, so as to coat the fibers while maintaining the space between the fibers constituting the antibacterial member 11A. That is, the coat film 11B has pores (not shown), and the components of the antibacterial agent contained in the antibacterial member 11A diffuse through the pores. Further, the coating film 11B suppresses the diffusion of the components of the antibacterial agent contained in the antibacterial member 11A, so that the antibacterial action can be maintained for a long period of time. Further, by forming the coat film 11B, water repellency, water resistance, strength, and antifouling property can be improved. The coating film 11B may be formed on only one side of the antibacterial member 11A, but is preferably formed on both sides. This is because a higher effect can be obtained.

  The compound shown in Formula 1 that forms the coat film 11B can be obtained by condensing a monomer (for example, methyltrimethoxysilane). The reason that the number of main chains is n = 2 to 10 is that n = 1, that is, when a monomer is used, it takes a long time to polymerize, and a coat film 11B having sufficient strength can be manufactured in a short time. Is difficult. However, when n is 11 or more, conversely, when applied to a fiber material, the number of alkoxy groups and the like for polymerization on the fiber material is insufficient, and a coated film 11B having sufficient strength is produced. It becomes difficult to do. Therefore, n is a condensate of 2 to 10, especially n = 2 to 8.

  In general, when a condensate of the formula 1 is synthesized from a monomer, it is practically impossible to precisely control the degree of polymerization from a technical point of view. Therefore, the use of n = 2 to 10, preferably n = 2 to 8, means that mainly n is 2 to 10, preferably 2 to 8, in view of the distribution of the degree of polymerization. The use of such a silane-based coating solution is unavoidable. For example, even if a compound in which n is 11 or more is contained, there is no problem.

  Specific examples of the compound represented by Formula 1 include methyltrimethoxysilane, ethyltrimethoxysilane, propyltrimethoxysilane, butyltrimethoxysilane, methyltriethoxysilane, ethyltriethoxysilane, propyltriethoxysilane, and butyltrimethoxysilane. Condensates such as ethoxysilane, methyltripropoxysilane, and ethyltripropoxysilane can be exemplified. The compound of the formula 1 may be a mixture of only one of these monomers, or a mixture of two or more of the above exemplified monomers.

The primary role of the non-hydrolyzable substituent (R ₄ ) in the compound of the formula 1 is to give flexibility to the coat film 11B, and at the same time, to impart water repellency to the coat film 11B. In the formula, R ₄ is preferably an alkyl group. Generally, the organic substituent increases the organic property, that is, the water repellency, as the number of carbon atoms increases. However, when the number of carbon atoms becomes too large, a steric hindrance causes strain in the coat film 11B and causes a decrease in the strength of the film. . Therefore, it is preferable to appropriately determine the number of carbon atoms of the alkyl group and the type and amount of each monomer constituting the compound of formula 1 (condensate) according to the purpose. However, imparting water repellency to the coat film 11B can also be achieved by adding a compound of formula 2 or formula 3 described below, and it is essential that R ₄ in the compound of formula 1 be an alkyl group. Do not mean.

  As a catalyst for curing and solidifying the compound represented by the formula 1, a commonly used catalyst can be used without any particular limitation. For example, in the case of an acid catalyst, hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid, formic acid or acetic acid can be exemplified. Examples of the base catalyst include ammonia, tetramethylammonium hydroxide, 2-hydroxyethyltrimethylammonium hydroxide, ethanolamine, diethanolamine, and triethanolamine. When these ordinary catalysts are used, reaction water is allowed to coexist in order to cure and solidify the compound of Formula 1.

  The silane-based coating liquid thus contains the compound of the formula 1, the catalyst and the reaction water. There is no particular problem when used normally, but when it is stored for a long time, there is a problem that the silane-based coating solution is easily gelled by the reaction water. In order to solve this, it is preferable to use a hydrolyzable organometallic compound as the catalyst instead of the usual catalyst as described above. Use of a hydrolyzable organometallic compound eliminates the need for coexisting reaction water, which is preferable because of long-term storage stability.

  When an organometallic compound is mixed with a compound of the formula 1 to form a silane-based coating solution, and applied to a fibrous material, it absorbs moisture on the fibrous material or moisture (humidity) in the air and hydrolyzes the organometallic compound itself. However, at this time, a network is formed with the compound of the formula 1, and the compound of the formula 1 is cured and solidified. Preferred examples of the organometallic compound include those containing titanium, zircon, aluminum or tin. More specifically, examples thereof include tetrapropoxytitanate, tetrabutoxytitanate, tetrapropoxyzirconate, tetrabutoxyzirconate, tripropoxyaluminate, aluminum acetylacetonate, dibutyltin diacetate, and dibutyltin dilaurate.

  In addition, an organic solvent can be added to the silane-based coating solution in order to uniformly mix the compound of the formula 1, the catalyst, and optionally required reaction water. Examples of the organic solvent used for this purpose include alcohols. More specifically, examples include methanol, ethanol, propanol, isopropanol, butanol, pentanol and hexanol. Further, by controlling the amount of addition, the viscosity and drying rate of the silane-based coating liquid can be adjusted.

  For the purpose of such adjustment, in particular, for example, glycols such as ethylene glycol, propylene glycol, diethylene glycol, polyethylene glycol, dipropylene glycol, polypropylene glycol, methoxyethanol, propoxyethanol, butoxyethanol, methoxypropanol, ethoxypropanol, propoxypropanol Alternatively, it is preferable to use an organic solvent having a high viscosity and a high boiling point, such as cellsolves such as butoxypropanol, alone or as a mixture of two or more. Of course, the above-mentioned alcohols may be added together with at least one of the above-mentioned organic solvents having a high viscosity and a high boiling point. When the purpose is to adjust the viscosity or drying rate of the silane-based coating solution, the same effect can be achieved not only by the organic solvent but also by a surfactant.

  For example, since the above-mentioned glycols and cellosolves have a hydroxyl group in the molecule, they may be introduced into a siloxane bond network formed by a condensation reaction of the compound of the formula 1. Since glycols and cellosolves have organic properties, their introduction increases the organicity of the obtained coating film 11B, that is, the antibacterial member 11A.

  In the method of manufacturing the main body 11, first, an antibacterial agent is contained in a base made of an arbitrary fiber material to form an antibacterial member 11A. For example, an antibacterial agent or a solution containing an antibacterial agent is applied to the substrate, sprayed, or the substrate is dipped in the antibacterial agent or a solution containing the antibacterial agent. As the substrate, for example, non-woven fabric, cloth, paper and the like can be used.

  Next, the silane-based coating solution described above is applied to the antibacterial member 11A. Although a specific application method is not particularly limited, for example, the antibacterial member 11A is immersed in a silane-based coating solution, the silane-based coating solution is applied to the antibacterial member 11A, or the silane-based coating solution is applied to the antibacterial member 11A. It can be performed by spraying. When the silane-based coating liquid is applied, the compound of the formula 1 is hydrolyzed, and a siloxane bond (Si-O-Si) is generated through the reactions shown in the following reaction formulas (1) to (3).

Reaction formula 1;
(1) Si-OR + H ₂ O → Si-OH + ROH
(2) Si—OH + HO—Si → Si—O—Si + H ₂ O
(3) Si—OH + RO—Si → Si—O—Si + ROH

  The bond energy of Si—O in the siloxane bond (Si—O—Si) thus generated is 106 kcal / mol. On the other hand, the bond energy of a CC bond, which is a typical bond of an organic compound, is 82.6 kcal / mol. Therefore, it can be seen that the vitreous coat film having a siloxane bond, which is formed by hydrolysis of the compound of Formula 1, has a bond that is far more thermally stable than the organic compound. Due to this thermally stable bond, the coating film 11B has excellent water repellency, stain resistance, heat resistance and abrasion resistance, and as a result, has excellent water repellency, stain resistance, heat resistance and abrasion resistance. The main body 11 can be manufactured.

  Further, when the silane-based coating liquid contains the above-mentioned organometallic compound (for example, tetrabutoxytitanium) as a catalyst, (1) in the above-mentioned reaction formula 1 even if reaction water is not contained in the silane-based coating liquid. The reactions of (3) to (3) proceed, and the reaction in this case is specifically as shown in (4) and (5) in the following reaction formula 2.

Reaction formula 2;
(4) Ti-OR + H ₂ O → Ti-OH + ROH
(5) Ti-OH + RO-Si → Ti-O-Si

  As described above, by introducing the Ti—O bond into the coat film, the water repellency, antifouling property, heat resistance, and abrasion resistance can be further improved as compared with the coat film 11B having only a siloxane bond. . As described above, when an organometallic compound is used as a catalyst, not only is it unnecessary to allow reaction water to coexist, but also the water repellency, antifouling property, heat resistance, and abrasion resistance of the coating film 11B are further improved. Thus, the water repellency, stain resistance, heat resistance and abrasion resistance of the main body 11 can be further enhanced.

  Further, in this coat film 11B, by using a silane-based coating solution containing the compound of the formula 2 in addition to the compound of the formula 1, the compound of the formula 2 can be compared with the coat film 11B manufactured without using the same. It is possible to newly impart properties such as organic properties possessed by or to increase properties such as organic properties. The compound of formula 2 added for this purpose is a compound in which three of the four substituents are hydrolyzable substituents and the other one is a non-hydrolyzable substituent.

In the formula 2, R ₅ , R ₆ and R ₇ may be the same or different and each is a monomer composed of hydrogen or an alkyl group or an alkenyl group having 1 to 10 carbon atoms, and R ₅ O, R ₆₀ and The bond between R ₇ O and Si is an oligomer composed of a siloxane bond, and R ₈ has an alkyl group, an alkenyl group or an alkyl group having 1 to 10 carbon atoms which may contain an epoxy group or a glycidyl group in the molecule. It is a phenyl group.

  Specific examples of the compound represented by the formula 2 include vinyltrimethoxysilane, phenyltrimethoxysilane, γ- (methacryloxypropyl) trimethoxysilane, γ-glycidoxypropyltrimethoxysilane, aminopropyltrimethoxysilane, β- (3,4 epoxycyclohexyl) ethyltrimethoxysilane, vinyltriethoxysilane, phenyltriethoxysilane, γ- (methacryloxypropyl) triethoxysilane, γ-glycidoxypropyltriethoxysilane, aminopropyltriethoxysilane And vinyltris (β-methoxyethoxy) silane, and condensates of about 2 to 10 molecules thereof.

  The compound of the formula 2 may be two or more of such monomers. When a condensate of two or more molecules is used as the compound of the formula 2, a compound obtained by condensing two or more of such monomers may be used.

  Further, in this coat film 11B, in addition to the silane-based coating solution containing the compound of the formula 1 or the silane-based coating solution containing both the compound of the formula 1 and the compound of the formula 2, the compound of the formula 3 is further added. By using the silane-based coating liquid thus obtained, a property such as organic property of the compound of Formula 3 is newly imparted or a property such as organic property is obtained as compared with the coat film 11B manufactured without using the silane-based coating liquid. It is possible to increase the properties.

The compound of Formula 3 is a compound in which two of the four substituents are hydrolyzable substituents and the other two are non-hydrolyzable substituents. In Formula 3, _{R 9} and _{R 11} may be the same or different, are hydrogen or a monomer consisting of an alkyl group or alkenyl group having 1 to 10 carbon atoms, and _{R 9} O and _{R 11} O and Si The bond is an oligomer composed of a siloxane bond, and R ₁₀ and R ₁₂ are an alkyl group, an alkenyl group, or a phenyl group having 1 to 10 carbon atoms which may contain an epoxy group or a glycidyl group in the molecule. .

  Specific examples of the compound represented by the formula 3 include dimethyldimethoxysilane, dimethyldiethoxysilane, diethyldimethoxysilane, diethyldiethoxysilane, diphenyldimethoxysilane, diphenyldiethoxysilane, methylvinyldimethoxysilane, and methylvinyldiethoxysilane. And condensates of about 2 to 10 molecules of these. The compound of formula 3 may be a mixture of two or more of such monomers, and even when a condensate of two or more molecules is used, two or more of such monomers may be used. May be.

  As described above, by adding either the compound of the formula 2 or the compound of the formula 3 to the silane-based coating solution, the organic property of the coating film 11B can be increased. When added to the system coating liquid, the organic property of the coating film 11B can be further improved, and as a result, the water repellency of the main body 11 can be further improved.

  In general, it is preferable to add the compound of the formula 2 and the compound of the formula 3 to the silane-based coating solution in a total amount not exceeding 50% of the compound of the formula 1. If the total amount of both exceeds this range, when the silane-based coating liquid is applied to the antimicrobial member 11A, the silane-based coating liquid does not bond well with the compound of the formula 1 as the main component, and the strength of the coating film 11B is insufficient. This is because there is a possibility that Therefore, when adding the compound of the formula 2 or the compound of the formula 3, it is assumed that the strength of the coat film 11B is reduced depending on the addition amount, and the range of the addition amount that can achieve the purpose is clarified. In addition, it is preferable to minimize the addition.

The primary role of the non-hydrolyzable substituents (R ₈ , R ₁₀ , R ₁₂ ) in the compound of formula 2 and the compound of formula 3 is to give flexibility to the coat film 11B. Since these are organic substitutions such as alkyl groups, they also serve to impart water repellency to the coat film 11B. Generally, the organic substituent increases the organic property, that is, the water repellency, as the number of carbon atoms increases. However, when the number of carbon atoms becomes too large, a steric hindrance causes strain in the coat film 11B and causes a decrease in the strength of the film. . Therefore, it is preferable to appropriately determine the number of carbon atoms of the organic substituent and the type and amount of each monomer constituting the compound (condensate) of the formula 2 or 3 according to the purpose.

  A siloxane bond having strong heat resistance and abrasion resistance is also a so-called "hard" bond. Due to this "hardness", when applied to a fiber material such as cloth, it is possible to impart abrasion resistance to the material. However, a fiber material such as cloth is characterized by having flexibility, and the body portion 11 is sometimes required to have the same flexibility as that of the material such as cloth.

Conventionally, generally used sol-gel coating solutions use tetraalkoxysilane (Si (OR) ₄ ) or an oligomer thereof as a starting material. When this is completely subjected to a hydrolysis reaction ((1) to (3) in the above reaction formula 1) to form a coat film 11B, all four bonds of silicon atoms form a hard siloxane bond network, Although it is hard like ceramic, it becomes a brittle film lacking in flexibility, so that it was practically impossible to manufacture the main body 11 utilizing the flexibility of cloth or the like.

  However, in the coating film 11B, this problem is solved by using, as a main component of the silane-based coating liquid, a compound of Formula 1 in which one of the four substituents of the silicon atom is not hydrolyzed. . Further, the flexibility and the like can be further increased by adding the compound of the formula 2 and the compound of the formula 3 each having one or two substituents that are not hydrolyzed to the silane-based coating solution.

  As described above, according to the present embodiment, a silane-based coating solution containing a compound represented by Formula 1 as a main component is applied to the surface of the antibacterial member 11A, and the coating film 11B cured and solidified by the action of a catalyst is formed. Since the antimicrobial agent is formed, the antimicrobial agent component can be diffused outside through the pores of the coat film 11B while the antimicrobial agent component is suppressed from being diffused by the coat film 11B. Therefore, the growth of bacteria can be suppressed by the antibacterial action, and the antibacterial action can be maintained for a long period of time. Further, since the water repellency, water resistance, strength, and antifouling property can be improved by the coat film 11B, deterioration can be suppressed, and long-term use or repeated use can be achieved.

  In particular, the antibacterial agent is indigo, indigo extract, tryptansulin, rush, rush extract, chlorogenic acid, kumasasa, kumasasa extract, diethyl ether, mugwort, mugwort extract, zioner, shiso, shiso extract Product, perylaldehyde, luteolin, light load, light load extract, olive leaf, olive leaf extract, oleuropein, chromium, chromophore extract, linalool, geraniol, hinoki, hinoki extract, hinokitiol, hiba, Hiba extract, cedar, cedar extract, fir, fir extract, bamboo, bamboo extract, sansho, sansho extract, mulberry, mulberry extract, oregano, oregano extract, carvacrol, Tea tree, tea tree extract, terpinen 4-ol, cinnamon, cinnamon extract, cinnamon aldehyde, cinnamon leaf, cinnamon leaf Extract, clove, clove extract, eugenol, rosemary, rosemary extract, rosmarinic acid, eucalyptus, eucalyptus extract, cineole, mint, mint extract, menthol, lavender, lavender extract, echinacea , Echinacea extract, Lemongrass, Lemongrass extract, Citral, Thyme, Thyme extract, Peppermint, Peppermint extract, Lemon myrtle, Lemon myrtle extract, Ravensala, Ravensala extract, Sage, Sage extract A higher effect can be obtained by including at least one selected from the group consisting of a product, winter savory, and an extract of winter savory.

  FIG. 3 shows the results of a cation permeation experiment of the coat film 11B. In the transmission experiment shown in FIG. 3, a paper was coated with a silane-based coating liquid containing the compound represented by Formula 1 as a main component, and a coating film 11B cured and solidified by the action of a catalyst was used. Is placed between two glass containers, the sample solution is put in one glass container, pure water is put in the other glass container, and after a predetermined time, the solution is collected from both glass containers, The change in the concentration of the substance (how much the solute substance permeated) was measured by FAB-MS (high-speed electron impact method). As the sample solution, a lithium chloride solution, a sodium chloride solution, a potassium chloride solution, or an ammonium chloride solution was used, and the initial concentration of each of the sample solutions was 0.2 mol / L. As shown in FIG. 3, cation permeability was confirmed. That is, it is understood that the formation of the coat film 11B allows the antimicrobial agent component to diffuse outward through the pores while suppressing the diffusion of the antimicrobial agent component.

(Second embodiment)
FIG. 4 shows a cross-sectional configuration of a mask 20 according to the second embodiment of the present invention. This mask 20 differs from the mask 10 of the first embodiment in the configuration of the main body 21. Therefore, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

As in the first embodiment, the main body 21 may have a pleated structure capable of expanding outward. The antibacterial member 21A has the same configuration as the antibacterial member 11A of the first embodiment. The coating member 21B is, for example, a coating film obtained by applying a silane-based coating solution containing a compound represented by Formula 1 as a main component to at least a part of a base material 21C made of a fiber material, and curing and solidifying the coating solution by the action of a catalyst. 21D is formed. Even with such a configuration, similarly to the first embodiment, the antibacterial agent component is diffused outside through the pores of the coat film 21D while the diffusion of the antibacterial agent component is suppressed by the coat film 21D. be able to.
