Description

  The present invention relates to a mask used by being worn on a human face, and more particularly to a transparent mask that makes it easy to visually recognize a wearer's mouth from the outside.

  2. Description of the Related Art Conventionally, masks that are used while being worn on a human face are known. For example, in hospitals where microorganisms are likely to spread, nursing care facilities where there is concern about infection to the elderly, construction sites where fine dust is likely to be generated, etc. A mask covering the nostril is worn for the purpose of preventing the intrusion. In recent years, since the number of people suffering from hay fever is increasing, the number of people wearing masks as a countermeasure against hay fever is also increasing.

  By the way, the conventional mask is constituted by using a woven or non-woven fabric of natural fibers such as gauze as a filter so as not to disturb the wearer's breathing while securing the capturing of fine foreign substances.

  However, since the mask having such a conventional structure does not have translucency, the mask of the wearer is covered and the facial expression of the wearer cannot be seen from the outside. For this reason, wearing a mask tended to give intimidation and fear to others.

  In particular, in hospitals and nursing homes, employees are often required to wear a mask. On the other hand, children and elderly people may feel anxious about the employee wearing the mask. In addition, even at construction sites, wearing a mask may not be able to sufficiently communicate with others, which may hinder work.

  In order to solve such a problem, Japanese Patent Application Laid-Open No. 2009-11475 (Patent Document 1) forms a region covering the front surface of the face with a transparent resin sheet, and allows the bottom portion located under the chin to be breathable. A transparent mask having a composite structure formed by a filter has been proposed. However, since the transparent resin sheet has almost no breathability, it feels difficult to breathe, and there is a problem that it tends to become cloudy due to breathing, and it has a shape that protrudes greatly forward from the face for structural reasons, and to others There was a problem that it was easy to give a strange feeling.

  Japanese Patent Laid-Open No. 10-146396 (Patent Document 2) proposes a mask made of a synthetic resin fiber having translucency, but the mask having such a structure has sufficient transparency and filterability. It was difficult to achieve both. That is, even if the fiber is made translucent, it has been difficult to obtain sufficient transparency of the mask due to refraction and reflection of light on the fiber surface. Moreover, the translucent fiber has a single-line structure extending in a constant cross section, which is different from a natural fiber which is a continuous fiber with a large number of fibers such as conventional cotton yarn. Therefore, even if a cloth-like body is composed of a large number of fibers as a woven fabric or a non-woven fabric, there is no fuzz like natural fibers in each fiber, and there is no gap between twists, so the fiber surface area is also reduced. In addition, it is difficult to realize a small gap, and the filter function is inevitably lowered as compared with conventional natural fibers such as cotton yarn. Therefore, it has been difficult to obtain sufficient transparency and filterability with a mask having a conventional structure using resin fibers having translucency as described in Patent Document 2.

JP 2009-11475 A Japanese Patent Laid-Open No. 10-146396

  The present invention has been made in the background of the above-mentioned circumstances, and the solution is to improve the transparency and air permeability, and at the same time achieve a high level of filterability against minute foreign matter. It is to provide a transparent mask having a simple structure.

  Hereinafter, the aspect of this invention made | formed in order to solve such a subject is described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible.

  The first aspect of the present invention is configured using a cloth-like body made of a translucent fiber having translucency, and the translucency of the cloth-like body is formed by pores formed between the translucent fibers. Transparency is set so that the outline of the mouth can be visually recognized from the outside when air permeability is improved and a permeation inhibitor that suppresses permeation of minute foreign matters floating in the air is attached to the light-transmitting fiber. Is a transparent mask characterized by

  According to the transparent mask having a structure according to this aspect, a cloth-like body configured by, for example, braiding, woven, or non-woven structure of translucent translucent fibers is employed, and such a cloth is used. The pores are provided in the cylindrical body. In this way, by intentionally forming pores having a predetermined area on the cloth-like body, a stable light beam is not affected by light refraction or reflection at the fiber surface or fiber inner surface at the pore formation position. Transmission performance is ensured and visibility by visible light transmitted through the mask is provided. Therefore, not only by the translucency of the fiber itself but also by transparency through the pores, when wearing a mask, the wearer's mouth can be easily seen from the outside.

  Further, the air permeability can be improved not only by the inter-fiber gaps of the cloth-like body constituted by a braided, woven or non-woven fabric structure but also by pores. Therefore, compared to the case where a transparent resin sheet having a conventional structure is adopted, the wearer's exhalation and inhalation of the inhalation can be facilitated, and the air permeability is improved and the cloudy Problems such as adhesion of water droplets can also be avoided.

  In addition, in the transparent mask of this aspect, the pores as described in detail are provided by attaching a permeation inhibiting agent that inhibits the transmission of minute foreign matter to the translucent fibers constituting the cloth-like body. While ensuring the effect of improving transparency and air permeability, it was possible to realize a good filter function for capturing minute foreign matters.

  That is, by providing the pores as described above, the air permeability and transparency are improved, but it is difficult to obtain sufficient filter performance due to the fact that the translucent fiber is generally made of a synthetic resin having a single wire structure. It will be an inherent problem. In short, air permeability, transparency and filterability are contradictory, and the present applicant has found an unprecedented new problem of achieving all of air permeability, transparency and filterability at a high level, This aspect has solved this problem. In this aspect, as described above, the transmission inhibitor is attached to the light-transmitting fiber to suppress the transmission of minute foreign matters, and sufficient filter properties are obtained. The light-transmitting fiber is formed from a light-transmitting fiber. Even in the case of a mask, all of air permeability, transparency and filterability can be exhibited at a high level.

  According to a second aspect of the present invention, in the transparent mask according to the first aspect, the permeation inhibitor is fluidized or gelled and can be attached to the surface of the translucent fiber.

  According to the transparent mask having a structure according to the present embodiment, since the transmission inhibitor is fluidized or gelled, for example, the translucent fiber is immersed in the transmission inhibitor, or applied with a brush or a finger. The permeation inhibitor can be easily attached to the surface of the light-transmitting fiber by spraying with a spray or by applying the same treatment to the cloth-like body.

  According to a third aspect of the present invention, in the transparent mask according to the first or second aspect, the permeation inhibitor has a charge characteristic that exerts an adsorption force or a repulsive force on the chargeable minute foreign matter. It is what.

  According to the transparent mask having the structure according to this aspect, since the permeation suppressor can be electrically adsorbed or repelled with respect to the minute foreign matter, the minute foreign matter having a charge due to ions or the like passes through the mask and is worn by the wearer. It can be effectively prevented from entering the nostrils.

  According to a fourth aspect of the present invention, in the transparent mask according to any one of the first to third aspects, the permeation inhibitor has antiviral properties.

  According to the transparent mask having a structure according to this aspect, since the permeation inhibitor has antiviral properties, it is suitably used in hospitals and nursing homes where there is concern about the spread of viruses that cause infectious diseases. obtain. In addition, the antiviral property in this aspect refers to the property of inactivating viruses that cause infectious diseases such as influenza viruses and noroviruses.

  According to a fifth aspect of the present invention, in the transparent mask according to any one of the first to fourth aspects, the permeation inhibitor has adhesiveness.

  According to the transparent mask having the structure according to this aspect, the transmission inhibitor has adhesiveness so that the minute foreign matters can be easily captured, and re-diffusion of the captured fine foreign matters can be more effectively prevented. In particular, regardless of the size and characteristics of the minute foreign matter, many types of minute foreign matter can be captured.

  A sixth aspect of the present invention is the transparent mask according to any one of the first to fifth aspects, wherein the light-transmitting fiber is 20% or more in a single item before the cloth-like body is formed. The visible light transmittance is as follows.

  According to the transparent mask having the structure according to this aspect, the visible light transmittance of the light-transmitting fiber in a single product state is set to 20% or more, so that the contour of the wearer's mouth can be visually recognized more clearly. .

  According to a seventh aspect of the present invention, in the transparent mask according to any one of the first to sixth aspects, in the front view of the cloth-like body, the total area of the pores is 10 of the total area of the cloth-like body. It is set within a range of ˜60%.

  According to the transparent mask having a structure according to this aspect, since the total area of the pores is set within a range of 10 to 60% of the total area of the cloth-like body, while ensuring air permeability stably, The shape of the mask is also stabilized, so that the wearer can wear it with a good fit.

  According to an eighth aspect of the present invention, in the transparent mask according to any one of the first to seventh aspects, the pores extend linearly in the thickness direction of the cloth-like body.

  According to the transparent mask structured according to this aspect, since the pores extend linearly in the thickness direction of the mask, visible light penetrates the cloth-like body linearly in the thickness direction and enters from the outside to the inside. Therefore, the visibility of the wearer's mouth from the outside can be further improved. Moreover, since the length of the pores can be shortened and the ventilation resistance can be reduced, the possibility that the wearer may feel stuffy during breathing can be reduced.

  According to a ninth aspect of the present invention, in the transparent mask according to any one of the first to eighth aspects, the region covering the mouthpiece in the mounted state is constituted by a single sheet of the cloth-like body. It is.

  According to the transparent mask having the structure according to this aspect, the wearer's mouth is covered only by one sheet of the cloth-like body in the wearing state, and therefore, for example, compared to a case where a plurality of cloth-like bodies are laminated. Further, the transparency and breathability of the mask in the mouth can be further improved.

  According to the transparent mask having a structure according to the present invention, transparency and air permeability can be improved by providing pores. In addition, by attaching a permeation inhibitor, it is possible to ensure the filterability of fine foreign matters while maintaining the transparency and air permeability of the pores well.

The front view which shows the transparent mask as one Embodiment of this invention. The front view which expands and shows the principal part of the transparent mask shown by FIG. III-III sectional drawing in FIG. Explanatory drawing for demonstrating the state which mounted | wore the human face with the transparent mask shown by FIG. Explanatory drawing for demonstrating the state which mounted | wore the human face with the transparent mask of another aspect of this invention. Explanatory drawing for demonstrating the state which mounted | wore the human face with the transparent mask of another aspect of this invention.

  Embodiments of the present invention will be described below with reference to the drawings.

  First, the transparent mask 10 as one Embodiment of this invention is shown by FIGS. 1-3. As shown in FIG. 4, the transparent mask 10 is worn by the wearer A to cover the nostril and oral cavity of the wearer A and prevent entry of minute foreign objects floating in the air into the nostril and oral cavity. It is supposed to be. Moreover, by having transparency, the outline of the mouth of the wearer A covered with the mask 10 can be visually recognized from the outside.

  Note that micro foreign substances floating in the air include, for example, microorganisms such as bacteria that cause infections, viruses, allergens that cause allergic reactions such as cedar and cypress pollen, and dust that is likely to be generated in homes and factory floors. And dust such as dust, asbestos, and house dust, and particulate matter that may adversely affect health such as PM10 and PM2.5.

  More specifically, the transparent mask 10 has a structure in which the ear straps 14 and 14 having flexibility are attached to the left and right ends of a single cloth-like body 12 having a substantially rectangular sheet shape having flexibility. Has been. For attachment of the ear straps 14 and 14 to the cloth-like body 12, means such as adhesion, welding, and stitching are preferably employed. Further, the ear straps 14 and 14 may be integrally formed with the cloth body 12. The material of the ear straps 14 and 14 is not limited, and may be formed of elastic materials such as rubber in addition to fibers of various materials.

  In this cloth-like body 12, at least a portion covering the nostril of the wearer A is a filter portion 16, while a support portion 18 that supports the filter portion 16 is provided on the outer peripheral portion of the filter portion 16. . In the present embodiment, the rectangular filter portion 16 is provided with a size slightly smaller than the cloth-like body 12, and the outer peripheral edge portion of the filter portion 16 is fixed to the rectangular frame-shaped support portion 18. .

  In addition, as a fixing means between the filter part 16 and the support part 18, means such as adhesion, welding, and stitching are suitably employed. Further, since the support portion 18 has a larger deformation rigidity than the filter portion 16, the shape of the cloth-like body 12 is held to a certain degree of stability. The support portion 18 may have transparency similarly to the filter portion 16, but may not be transparent. Moreover, the support part 18 can employ | adopt a grid | lattice shape etc. suitably besides rectangular frame shape. When the lattice-shaped support portion is employed, not only the outer peripheral portion of the filter portion 16 but also the entire cloth-like body including the central portion where the filter portion 16 is provided can be disposed.

  Here, the filter part 16 is comprised by the translucent fiber 20 which has several translucency, and has transparency. That is, the filter part 16 of this embodiment is made into a mesh shape by weaving a plurality of translucent fibers 20 and adjusting the roughness of the weave. Specifically, a plurality of light transmitting fibers 20 extending in one direction and a plurality of light transmitting fibers 20 extending in a direction perpendicular to the light transmitting fibers 20 are plain-woven to form a mesh-like filter portion 16.

  The mesh eyes (the gaps between the light-transmitting fibers 20) are the pores 22 through which the wearer A's inspiration or expiration can pass. Thereby, the air permeability of the transparent mask 10 is improved as compared with the case where such pores 22 are not provided. In FIGS. 1 to 3, the mesh size of the transparent mask 10 is shown larger than the actual size for easy understanding.

  In particular, in the present embodiment, at least a part of the pores 22 are formed so as to penetrate linearly in the thickness direction of the transparent mask 10 (left and right direction in FIG. 3), and visible light is transmitted through the pores 22. It can be directly transmitted. Moreover, in this embodiment, the cloth-like body constituting the filter unit 16 has a plain weave structure throughout, and when placed flat in a stretched state, a large number of pores 22 existing between the weaves are All of them have a structure penetrating in the thickness direction, and are substantially evenly provided at predetermined intervals over substantially the entire filter portion 16.

Here, in this embodiment, the pores 22 having a predetermined area are intentionally formed by adjusting the interval between the light-transmitting fibers 20 and the like. The size of the pores 22 is appropriately adjusted in consideration of the properties and thickness of the employed fibers according to the required characteristics, and is not limited. Illustratively, for example, preferably 0.02 mm ² or more 30 mm ² or less as the minimum cross-sectional area of the pores 22, 0.04 mm ² or more 25 mm ² or less being more preferred. That is, by setting it as 0.02 mm < ² > or more, favorable air permeability and the visibility of the wearer's A mouth are exhibited. On the other hand, by setting the thickness to 30 mm ² or less, the filter property against minute foreign matters is stably exhibited together with the action of the permeation inhibitor 24 described later.

  Further, the total amount of pores 22 (total flow area) is appropriately determined according to required characteristics and is not limited. Illustratively, for example, when the cloth-like body 12 is viewed from the front, the total area of the pores 22 is preferably set within a range of 10% to 60% of the total area of the cloth-like body 12. That is, when the total area of the pores 22 is less than 10% of the total area of the cloth-like body 12, the air permeability cannot be sufficiently secured, and the wearer feels stuffy when wearing the transparent mask, There is a possibility that the wearer's mouth cannot be sufficiently visually recognized due to reflection and refraction of visible light. On the other hand, when the total area of the pores 22 is larger than 60% of the total area of the cloth-like body 12, there is a possibility that the filter property with respect to the minute foreign matter cannot be sufficiently secured.

  Further, the type and thickness of the translucent fiber 20 are not limited at all. Illustratively, for example, the diameter of the translucent fiber 20 is preferably set within a range of 20 μm to 500 μm, and more preferably within a range of 30 μm to 200 μm. By setting the diameter of the translucent fiber 20 within the above range, the pores 22 are easily formed, and the strength of the transparent mask 10 can be sufficiently secured.

  In addition, the method of forming the mesh-shaped filter part 16 is not limited to the woven structure by plain weaving as described above. For example, in addition to various woven structures, various braided structures can also be employed, and furthermore, a nonwoven fabric structure by welding with heat or chemicals can also be employed. Specifically, for example, a plurality of translucent fibers may be formed by weaving or knitting by a conventionally known knitting method such as twill weave, satin weave, knitted fabric, rubber knitting or pearl knitting. Or you may be set as the nonwoven structure by a translucent fiber. Specifically, for example, a plurality of translucent fibers extending in one direction and a plurality of translucent fibers orthogonal to each other, or facing or curved in an unspecified direction. The mesh-shaped filter part may be formed by superimposing each other and fixing the overlapping parts to each other by adhesion or welding. In any case, the pores as described above can be formed by adjusting the interval between the light transmitting fibers.

  Furthermore, the material of the translucent fiber 20 is not limited at all as described above. For example, polyolefin, polyester, polyamide, polyurethane, and the like can easily achieve high translucency, and can be easily processed. Various synthetic resins that do not adversely affect the human body and the environment can be suitably employed.

  The translucent fiber 20 has a visible ray parallel light transmittance α (JIS K7105) of preferably 20% or more in a single product state (single fiber state) before constituting the cloth-like body 12. More preferably, it is set to 25% or more. When the cloth-like body 12 is configured using such a light-transmitting fiber 20, since the pores 22 are formed, the positions where the pores 22 are formed (in this embodiment, the abbreviated shape of the cloth-like body 12). The parallel light transmittance β of the cloth-like body 12 in the whole) is improved more than the parallel light transmittance α of the translucent fiber 20 in the single product state.

  That is, in FIG. 2, the portion where only one light-transmitting fiber 20 is present has a parallel light transmittance of α, but the portion where two light-transmitting fibers 20 overlap has a parallel light transmittance of less than α. Become. On the other hand, since the parallel light transmittance of the pores 22 penetrating in the thickness direction of the cloth-like body 12 is 100%, the parallel light transmittance β of the cloth-like body 12 in the entire position where the pores 22 are formed is averaged. Thus, the parallel light transmittance α of the translucent fiber 20 in the single product state is improved. The parallel light transmittance β of the cloth-like body 12 is set to 10% or more on average, and more preferably set to 15% or more. By setting the parallel light transmittance β of the cloth-like body 12 within the above range, the mouth of the wearer A can be visually recognized from the outside.

  Here, the light transmission fiber 20 constituting the cloth-like body 12 is attached with a transmission inhibiting agent 24 that inhibits transmission of minute foreign matters floating in the air through the transparent mask 10. The permeation inhibitor 24 is indicated by a thick black line in FIGS. As the permeation inhibitor 24, for example, a material that suppresses permeation of minute foreign substances by adsorption or repulsion is employed.

  Although the specific example of the permeation | transmission inhibitor 24 is illustrated below, this permeation | transmission inhibitor 24 can be made to adhere to the surface of the translucent fiber 20 partially or substantially entirely. In the case where the transmission inhibitor 24 is attached over substantially the entire surface of the light-transmitting fiber 20, the transmission inhibitor 24 is preferably excellent in visible light transmittance. By attaching the transmission inhibitor 24, it is desirable that the parallel light transmittance α of the translucent fiber 20 is not significantly reduced, and the parallel light transmittance β of the cloth-like body 12 can be set in the above-described preferable range. Is preferred.

  That is, for example, when the permeation inhibitor 24 inhibits the permeation of minute foreign substances by an adsorption action, the permeation inhibitor 24 has, for example, a certain degree of adhesiveness, and the fine foreign substances are sticky to the permeation inhibitor 24. As a result, the permeation of minute foreign matter is suppressed.

  Examples of the adhesive permeation inhibitor 24 include antiviral, antibacterial, and bactericidal agents, natural or synthetic polymer substances, and those added with an additive that provides adhesiveness. Can be mentioned. When an antiviral agent, an antibacterial agent, or a bactericidal agent is used as the permeation inhibitor 24, the virus or bacteria activity is lost by being trapped by the permeation inhibitor 24. Even if bacteria or bacteria are detached from the permeation inhibitor 24 and inhaled by the wearer A, the risk of causing an infection can be reduced. Specifically, for example, a silicon-containing compound described in Japanese Patent No. 4830075 is suitably used as a drug exhibiting antiviral properties and antibacterial properties. As the polymer substance, for example, an elastic resin such as acrylic resin, natural rubber, styrene-butadiene rubber, styrene-isopropylene rubber, butyl rubber, polyisoprene, and silicone resin is preferably used.

  Further, for example, the permeation inhibitor 24 may be configured to electrically adsorb minute foreign matters. That is, when the permeation inhibitor 24 has a positive or negative charge, a minute foreign substance having an opposite charge can be electrically adsorbed. As the permeation inhibitor 24, for example, a solution having positive ions or negative ions can be adopted, and minute foreign matters having opposite charges (ions) can be adsorbed. Alternatively, the permeation inhibitor 24 may be, for example, a substance that forms an artificial static electricity region. For example, the compounds described in Japanese Patent No. 4870431 may be suitably employed.

  Further, porous activated carbon powder or the like may be employed as the permeation inhibitor 24. By adopting such a porous substance, it is possible to capture and adsorb minute foreign matters in the pores. The solid permeation inhibitor can be attached to the fiber surface using, for example, an adhesive or a pressure-sensitive adhesive, or can be mechanically fixed between the fibers. Furthermore, a solvent such as water may be employed as the permeation inhibitor 24. Thereby, for example, soluble fine foreign substances can be adsorbed and dissolved and captured in the permeation inhibitor 24.

  Alternatively, when the permeation inhibitor 24 inhibits the transmission of minute foreign substances by a repulsive action, for example, the permeation inhibitor 24 may be a compound described in the above-mentioned Japanese Patent No. 4870431 or a positive or negative charge (plus ion or And solutions having negative ions). Thereby, the permeation | transmission of the micro foreign material which has the same electric charge is suppressed. Or as the permeation | transmission inhibitor 24, the hydrophobic substance etc. which show water repellency are mentioned. Thereby, the permeation | transmission of a liquid minute foreign material can be suppressed. As such a hydrophobic substance, polytetrafluoroethylene (PTFE) or the like can be suitably employed. In addition, as a liquid micro foreign material, the droplet by the sneeze of an infectious disease patient etc. are mentioned, for example.

  Alternatively, it is also possible to employ a photocatalyst powder such as titanium oxide as the permeation inhibitor 24. In such a photocatalyst, an oxidizing power is generated on the surface of the photocatalyst when it is exposed to light such as the sun or a fluorescent lamp, and these are decomposed when pollen, bacteria, etc. come into contact with the surface of the photocatalyst. Therefore, even if such a photocatalyst is used, permeation of minute foreign matters is suppressed. In particular, since titanium oxide has superhydrophilicity, it can adsorb water molecules, for example, and can also prevent permeation of liquid fine foreign matter.

  The permeation inhibitor 24 as described above is preferably fluidized or gelled. The fluid or gel permeation inhibitor 24 is preferably in the state of, for example, an ointment, paste, cream or gel. Thereby, the transmission inhibitor 24 can be applied to the light transmitting fiber 20 with a brush or the like, and the transmission inhibitor 24 can be more reliably attached to the surface of the light transmitting fiber 20. Moreover, when the permeation | transmission inhibitor 24 is made into a liquid with low viscosity, it is also possible to immerse the translucent fiber 20 in the permeation | transmission inhibitor 24 or to spray the translucent fiber 20 with a spray. In addition, the permeation | transmission inhibitor 24 may adhere to the fiber surface in the dry state, for example, when exhibiting a function in a dry state like the effect | action of an electric charge or a photocatalyst.

  As shown in FIG. 4, the transparent mask 10 having such a structure hooks the ear straps 14 and 14 on both ears of the wearer A, and the sheet-like cloth-like body 12 covers the nostril. It is attached in this way. Thereby, it can prevent that a micro foreign material permeate | transmits the transparent mask 10, and penetrate | invades into a wearer's nostril and oral cavity. Moreover, since the filter part 16 is formed with the translucent fiber 20 which has translucency, the outline of the mouth of the wearer A can be visually recognized from the outside. Note that in such a mounted state, the sheet of the cloth-like body 12 covers the mouth of the wearer A without being bent and overlapping in the thickness direction.

  Here, in the transparent mask 10, the air permeability and transparency are improved by providing the pores 22 in the cloth-like body 12 as compared with the case where the pores 22 are not provided. In particular, since the pores 22 extend in the thickness direction of the transparent mask 10, the light passing through the pores 22 goes straight without being refracted or reflected by the light-transmitting fibers 20. Therefore, the parallel light transmittance of visible light in the portion where the pores 22 are formed can be further improved. Moreover, since the passage of the inhalation and expiration of the wearer A can be shortened, the air permeability can be further improved.

  Further, since the transmission inhibitor 24 is attached to the light transmitting fiber 20, even if the pores 22 are provided in the cloth-like body 12, the permeation of minute foreign matters can be prevented stably without impairing the filter performance.

  Moreover, since the part which covers the wearer's A mouth is the sheet-like cloth-like body 12, compared with the case where the mouth of the wearer A is covered with a plurality of cloth-like bodies, for example. The air permeability and transparency of the transparent mask can be improved.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the specific descriptions in the embodiments, and various changes, modifications, improvements, and the like based on the knowledge of those skilled in the art. It is feasible in the form which added.

  For example, in the above-described embodiment, the gaps between the translucent fibers 20 are the pores 22. However, for example, a punching process is performed on a cloth-like body in which a plurality of translucent fibers are knitted or bonded to each other without gaps. And the pores may be constituted by the through holes. The pores (filter part) need not be formed over the entire cloth-like body, but may be formed only in the mouth part so that the outline of the mouth can be visually recognized from the outside. Furthermore, in order to stabilize the shape of the transparent mask, a frame-like or lattice-like reinforcing member may be fixed to the cloth-like portion, and pores are provided at positions where the reinforcing member is avoided in the cloth-like portion. Also good.

  Furthermore, in the said embodiment, although the substantially whole cloth-like body 12 was made into the filter part 16 and was formed with the translucent fiber 20 which has translucency, it is not limited to this aspect. That is, for example, as shown in FIG. 5, an opening 28 is provided in a mouth portion of a mask 26 made of natural fibers having a conventional structure, and a cloth-like body 30 made of light-transmitting fibers so as to cover the opening 28. May be attached from the front surface or the back surface of the mask 26.

  Furthermore, in the above embodiment, the transparent mask 10 is constituted by a single sheet-like cloth body 12, but for example, as shown in FIG. 6, it is constituted by a plurality of cloth-like bodies 32,. It may be. That is, in the cloth-like body 32 made of a light-transmitting fiber, the opening 36 is provided in the mouth portion, and the cloth-like body 34 made of the light-transmitting fiber is placed on the surface of the cloth-like body 32 so as to cover the opening 36. Or it may be pasted from the back. The number and size of pores provided in the cloth-like bodies 32 and 34 may be different from each other. For example, the cloth-like body that directly covers the mouth of the wearer A with respect to the pores in the cloth-like body 32. It is also possible to make the wearer A breath more smoothly by increasing the size of the pores at 34 or increasing the number of pores.

  Furthermore, in the said embodiment, although the sheet-like cloth-like body 12 was attached to the wearer A without overlapping in the thickness direction and covered the mouthpiece, it is not limited to this aspect. Absent. That is, for example, a sheet-like cloth-like body may be folded in the length direction (left-right direction in FIG. 1) or in the width direction (up-down direction in FIG. 1) to have a pleat shape overlapping in the thickness direction. Good. By overlapping in the thickness direction in this way, not only the filter property is improved, but also the size of the mask can be adjusted by extending the pleats. Even if the mask cloth is provided with pleats, the pleats will be stretched when worn, and the overlap of the cloths will be reduced by extending the pleats, improving visibility from others. obtain. However, the sheet-like cloth-like body is not limited to one sheet, and a plurality of cloth-like bodies may be partially overlapped as in the aspect shown in FIG. The cloth-like body may overlap all over.

  Moreover, in the said embodiment, after making the permeation | transmission inhibitor 24 adhere to the translucent fiber 20, the filter part 16 was formed using the said translucent fiber 20, However, It is not limited to this aspect. That is, after forming a transparent mask using translucent fibers, a liquid permeation inhibitor is sprayed from the front or back surface of the mask, or a gel-like permeation inhibitor is applied and adhered. Also good. Thus, after forming the mask, not only can the permeation inhibitor be attached, but also the permeation inhibitor can be carried inside the pores in addition to the surface of the light transmitting fiber. It becomes possible. In addition, when a permeation inhibitor is required, it can be attached in a necessary amount, so that it is avoided that the permeation inhibitor is excessively attached, and the cost can be reduced. After attaching the permeation inhibitor, if necessary, remove excess permeation inhibitor, for example, by blowing compressed air using an air compressor, etc., or adjust the setting to an appropriate amount of permeation inhibitor. It is also possible to adjust the amount of adhesion of the permeation suppressant, thereby adjusting the breathability and thus the ease of breathing of the wearer. However, in addition to the permeation inhibitor previously adhered, it is also possible for the user to additionally attach a desired amount of permeation inhibitor to any location. You may make it adhere to. It is also possible to remove excess permeation inhibitor by the pressure accompanying breathing or exhalation of the wearer, etc. It is also possible to develop appropriate pores.

  Furthermore, in the above-described embodiment, the pores 22 extend linearly in the thickness direction of the cloth-like body 12, but the pores extend linearly inclining with respect to the thickness direction of the cloth-like body. Alternatively, it may extend in a curved or bent manner. Further, pores having different types of shapes and sizes may be provided in combination with the cloth-like body. The transparent fibers constituting the cloth-like body can also be used in combination with fibers of different materials.
