Unlike the cellulose fabric 9, the synthetic fiber fabric 11 is unlikely to protrude in the thickness direction T from the surface (skin facing surface or non-skin facing surface) of the synthetic fiber fabric 11. Therefore, even if the synthetic fiber fabric 11 comes into contact with the skin of the wearer, there is little possibility of giving a stimulus such as a tingling feeling to the wearer.
In addition, in this specification, a short fiber means a fiber with an average fiber length of 0.5-100 mm. Further, the long fiber means an average fiber length of more than 100 mm, and includes continuous fibers.

続いて、本実施形態に係るマスク１の作用を説明する。
本実施形態のマスク１は、前記プリーツ構造Ｐ及び両側縁部３ｃ、３ｃのそれぞれにおいて、縦方向（Ｌ）に沿って延在するエンボス部２９により、使用時において、マスク本体３の立体構造の保形性を維持し易い。また、マスク本体３が切欠き部１５を両側縁部３ｃ、３ｃのそれぞれにおいて備えることにより、切欠き部１５が変形誘導の起点となるので、使用時において、マスク本体３の顔面へのフィット性を高め易い。 Next, the operation of the mask 1 according to this embodiment will be described.
The mask 1 of the present embodiment has a three-dimensional structure of the mask body 3 in use by the embossed portion 29 extending along the longitudinal direction (L) in each of the pleat structure P and the side edge portions 3c and 3c. Easy to maintain shape retention. Further, since the mask body 3 is provided with the notches 15 at the respective side edges 3c and 3c, the notches 15 serve as starting points for deformation induction. Therefore, in use, the mask body 3 can be fitted to the face. Easy to increase.

また、本実施形態のマスク１は、マスク本体３において、着用者の鼻を覆うように配置され且つ所定の摩擦特性を有する合成繊維布帛からなる鼻カバー部３９を備えるので、鼻カバー部３９が着用者の顔面、特に鼻の部分に接触しても、当該部分に刺激を与えにくい。また、本実施形態のマスク１は、マスク本体３において、鼻カバー部３９を備えることにより、鼻カバー部３９を構成する合成繊維布帛よりもＭＩＵ又はＭＭＤが高く、着用者の顔面に触れたときに当該顔面に刺激を与え易いセルロース布帛９が、着用者の顔面、特に鼻の部分に直接接触することを抑制し易い。したがって、本実施形態のマスク１は、着用者の顔面における違和感を抑制し易く、装着感に優れる。
より具体的には、マスク本体３の肌対向面Ｓ１の少なくとも一部がセルロース布帛９により構成されるので、セルロース系繊維の吸湿性により着用者がマスク本体３内で吐いた息を吸湿・蒸散させ易く、蒸れにくい。一方、マスク本体３の肌対向面Ｓ１の一部を構成するセルロース布帛９が、例えばガーゼ等、セルロース系の短繊維を撚り合わせた糸の編物から構成される場合、当該セルロース系短繊維の繊維端が当該肌対向面Ｔ１から厚さ方向Ｔに突出し易く、当該繊維端が着用者の肌に接触することにより、着用者にチクチク感等の刺激を与えることがある。しかしながら、マスク本体３が所定の位置に、合成繊維布帛からなる鼻カバー部３９を有することにより、当該チクチク感等の刺激や違和感を着用者に感取させにくくすることができる。
以上より、本実施形態のマスク１は、マスク１の吸湿性を高めつつ、着用者の顔面における違和感を抑制し易く、装着感に優れる。
なお、本実施形態のマスク１は、マスク本体３において、保持部材４１を備え、当該保持部材４１が設けられている部分においてはマスク本体３が着用者の鼻根部分に特に密着し易い。また、保持部材４１の剛性により、当該保持部材４１が設けられている部分においては、マスク本体３の肌対向面Ｓ１を介して着用者の鼻根部分に擦れ等、特に着用者に刺激を与え易い。そこで、本実施形態のように、鼻カバー部３９が保持部材４１を覆うように設けられていると、より確実に着用者の顔面における違和感を抑制し易い。 Moreover, since the mask 1 of this embodiment is provided with the nose cover part 39 which consists of a synthetic fiber fabric which is arrange | positioned so that a wearer's nose may be covered in the mask main body 3, and has a predetermined friction characteristic, Even if it touches the wearer's face, particularly the nose, it is difficult to irritate the part. Moreover, the mask 1 of this embodiment is provided with the nose cover part 39 in the mask main body 3, so that MIU or MMD is higher than the synthetic fiber fabric constituting the nose cover part 39, and the mask 1 touches the wearer's face. In addition, it is easy to suppress the cellulose fabric 9 that easily gives a stimulus to the face from directly contacting the wearer's face, particularly the nose. Therefore, the mask 1 of this embodiment is easy to suppress the uncomfortable feeling on the wearer's face, and is excellent in wearing feeling.
More specifically, since at least a part of the skin-facing surface S1 of the mask main body 3 is composed of the cellulose fabric 9, the breath exhaled by the wearer in the mask main body 3 due to the hygroscopic property of the cellulose-based fibers is absorbed and evaporated. It is easy to make it hard to stuffy. On the other hand, when the cellulose fabric 9 constituting a part of the skin-facing surface S1 of the mask body 3 is formed of a knitted yarn made by twisting cellulose short fibers such as gauze, the cellulose short fibers are used. The end tends to protrude from the skin facing surface T1 in the thickness direction T, and the fiber end comes into contact with the wearer's skin, which may give the wearer a stimulus such as a tingling sensation. However, by providing the mask body 3 with the nose cover portion 39 made of a synthetic fiber fabric at a predetermined position, it is possible to make it difficult for the wearer to sense irritation or a sense of discomfort.
As mentioned above, the mask 1 of this embodiment is easy to suppress the discomfort in a wearer's face, improving the hygroscopic property of the mask 1, and is excellent in a wearing feeling.
In addition, the mask 1 of this embodiment is provided with the holding member 41 in the mask main body 3, and the mask main body 3 is especially easy to adhere to a wearer's nasal root part in the part in which the said holding member 41 is provided. Further, due to the rigidity of the holding member 41, the wearer 41 is particularly irritating to the wearer's nasal root portion or the like through the skin facing surface S 1 of the mask body 3 in the portion where the holding member 41 is provided. easy. Therefore, when the nose cover portion 39 is provided so as to cover the holding member 41 as in the present embodiment, it is easier to more reliably suppress the uncomfortable feeling on the wearer's face.

また、本実施形態のマスク１は、マスク本体３の肌対向面Ｓ１の一部を構成する布帛がセルロース布帛からなるので、マスク本体の吸湿性をより確実に確保し易い。   Further, in the mask 1 of the present embodiment, since the fabric constituting a part of the skin facing surface S1 of the mask body 3 is made of a cellulose fabric, it is easy to ensure the hygroscopicity of the mask body more reliably.

また、本実施形態のマスク１は、セルロース布帛９を構成する繊維が、複数の短繊維を撚り合わせて構成されているので、前記短繊維の繊維端や前記短繊維を撚り合わせて構成された繊維束からはみ出た短繊維が、当該セルロース布帛９における肌対向面Ｓ１から着用者の顔面が存在する方向に突出し易く、着用者の顔面、特に鼻の部分にチクチク感等の刺激を与え易い。しかし、本実施形態のマスク１は、前記構成を有する鼻カバー部３９を所定の位置に備えるので、マスク本体３がこのように着用者の顔面、特に鼻の部分に刺激を与え易い質感のセルロース布帛９により構成されていても、着用者の顔面における違和感を抑制し易く、装着感に優れる。   Further, the mask 1 of the present embodiment is configured by twisting the fiber ends of the short fibers and the short fibers because the fibers constituting the cellulose fabric 9 are formed by twisting a plurality of short fibers. The short fibers protruding from the fiber bundle are likely to protrude from the skin facing surface S1 of the cellulose fabric 9 in the direction in which the wearer's face is present, and easily give a stimulus such as a tingling feeling to the wearer's face, particularly the nose. However, since the mask 1 of the present embodiment includes the nose cover portion 39 having the above-described configuration at a predetermined position, the mask body 3 thus has a textured cellulose that is likely to irritate the wearer's face, particularly the nose portion. Even if it is comprised by the fabric 9, it is easy to suppress the discomfort in a wearer's face, and it is excellent in a wearing feeling.

また、本実施形態のマスク１において、鼻カバー部３９を構成する前記合成繊維布帛に複数の点状エンボス部４５が設けられているにもかかわらず所定の範囲内のＳＭＤを有するので、マスク１の使用開始の段階において、鼻カバー部３９の凹凸感を着用者に感取され難く、着用者の顔面における違和感を抑制し易い。また、マスク１は、所定の点状エンボス部４５を複数有するので、鼻カバー部３９を構成する前記合成繊維布帛の毛羽立ちを抑制し易く、特に使用時間が一定程度経過しても、毛羽立ちが抑制された状態を維持し易く、着用者の顔面における違和感を抑制し易い。したがって、本実施形態のマスク１は、使用開始段階及び使用開始から一定程度時間が経過した段階のいずれにおいても、着用者の顔面における違和感を抑制し易く、装着感に優れる。   Further, in the mask 1 of the present embodiment, since the synthetic fiber fabric constituting the nose cover portion 39 has a plurality of point-like embossed portions 45, the mask 1 has an SMD within a predetermined range. At the stage of starting use, it is difficult for the wearer to sense the unevenness of the nose cover portion 39, and it is easy to suppress a sense of discomfort on the wearer's face. Further, since the mask 1 has a plurality of predetermined point-like embossed portions 45, it is easy to suppress the fluff of the synthetic fiber fabric constituting the nose cover portion 39, and in particular, the fluff is suppressed even after a certain period of use. It is easy to maintain the done state, and it is easy to suppress a sense of incongruity on the wearer's face. Therefore, the mask 1 of this embodiment is easy to suppress a sense of incongruity on the wearer's face at both the use start stage and the stage after a certain period of time has elapsed from the start of use, and is excellent in wearing feeling.

また、本実施形態のマスク１は、鼻カバー部３９とプリーツ構造Ｐとが上述の位置関係にあるので、セルロース布帛９が着用者の顔面に触れることをより抑制し易く、着用者の顔面における違和感をより確実に抑制し易い。   Moreover, since the nose cover part 39 and the pleat structure P are in the above-mentioned positional relationship, the mask 1 of this embodiment can suppress more easily that the cellulose fabric 9 touches a wearer's face, and in the wearer's face. It is easy to suppress uncomfortable feelings more reliably.

また、本実施形態のマスク１において、プリーツ構造Ｐ及び上述の構成を有するエンボス部２９により、使用時において、マスク本体３の立体構造の保形性を維持し易いと共に、マスク本体３が切欠き部１５を備えることにより、当該切欠き部１５が変形誘導の起点となるので、使用時において、マスク本体３の顔面へのフィット性を高め易い。
また、本実施形態のマスク１は、マスク本体３が、少なくとも両側縁部３ｃのそれぞれの切欠き部形成領域１７において、切欠き部１５を非肌対向面側Ｓ２及び肌対向面側Ｓ１から覆うサイドシート１３を備えるので、切欠き部１５が着用者の顔面に直接触れることを抑制し易いと共に、切欠き部形成領域１７の剛性は、切欠き部非形成領域１９の剛性よりも低く構成されているので、切欠き部形成領域１７が着用者の顔面に触れても、着用者の顔面における違和感を抑制し易い。
以上より、本実施形態のマスク１は、使用時において、マスク本体３の顔面へのフィット性を高めつつ、着用者の顔面における違和感をより確実に抑制し易い。 Moreover, in the mask 1 of this embodiment, the pleated structure P and the embossed portion 29 having the above-described configuration facilitate maintaining the shape retaining property of the three-dimensional structure of the mask body 3 during use, and the mask body 3 is notched. By providing the portion 15, the cutout portion 15 serves as a starting point for deformation induction, and thus it is easy to improve the fit of the mask body 3 to the face during use.
Further, in the mask 1 of the present embodiment, the mask body 3 covers the notch 15 from the non-skin facing surface side S2 and the skin facing surface side S1 at least in the notch portion forming regions 17 of the side edges 3c. Since the side sheet 13 is provided, it is easy to suppress the notch 15 from directly touching the wearer's face, and the rigidity of the notch formation region 17 is lower than the rigidity of the notch non-formation region 19. Therefore, even if the notch portion formation region 17 touches the wearer's face, it is easy to suppress a sense of discomfort on the wearer's face.
As described above, the mask 1 of the present embodiment can more easily suppress the uncomfortable feeling on the wearer's face while enhancing the fit of the mask body 3 to the face during use.

また、本実施形態のマスク１において、切欠き部形成領域１７がエンボス部を有しないので、当該切欠き部形成領域１７が着用者の顔面に触れても、本実施形態のマスク１は、着用者の顔面に刺激を与えにくく、着用者の顔面における違和感をより確実に抑制し易い。   Moreover, in the mask 1 of this embodiment, since the notch part formation area 17 does not have an embossed part, even if the said notch part formation area 17 touches a wearer's face, the mask 1 of this embodiment is worn. It is hard to give a stimulus to a person's face, and it is easy to suppress uncomfortable feeling in a wearer's face more reliably.

また、本実施形態のマスク１において、セルロース布帛９は、織物であるので吸湿性を維持しつつ通気性を有するので蒸れにくい。さらに、マスク本体３は、両側縁部３ｃのそれぞれにおける切欠き部１５において、合成繊維布帛１１が溶断されているので、溶断部分において合成繊維布帛１１とセルロース布帛９とが溶着し、両布帛の位置ずれを抑制し易いと共にマスク１の強度をより確実に確保し易く、マスク本体３の立体構造の保形性を維持し易いので、マスク本体３の顔面へのフィット性をより確実に確保し易く、着用者の顔面における違和感をより確実に抑制し易い。   Moreover, in the mask 1 of this embodiment, since the cellulose fabric 9 is a woven fabric, it has moisture permeability while maintaining moisture absorption, so that it is difficult to be stuffy. Further, since the synthetic fiber fabric 11 is fused at the notch 15 in each of the side edge portions 3c, the mask main body 3 is welded to the synthetic fiber fabric 11 and the cellulose fabric 9 at the fused portion. Since it is easy to suppress misalignment and to ensure the strength of the mask 1 more reliably and to maintain the shape retaining property of the three-dimensional structure of the mask body 3, it is possible to more reliably secure the fit of the mask body 3 to the face. It is easy to suppress the uncomfortable feeling on the wearer's face more reliably.

また、本実施形態のマスク１は、マスク本体３の下端縁３ｂ近傍において、セルロース布帛９が合成繊維布帛１１に覆われているので、下端縁３ｂ近傍において、セルロース布帛９が着用者の顔面に直接接触し難い。したがって、本実施形態のマスク１は、着用者の顔面における違和感をより確実に抑制し易い。   In the mask 1 of the present embodiment, since the cellulose fabric 9 is covered with the synthetic fiber fabric 11 in the vicinity of the lower end edge 3b of the mask body 3, the cellulose fabric 9 is placed on the wearer's face in the vicinity of the lower end edge 3b. Hard to touch directly. Therefore, the mask 1 of the present embodiment can more reliably suppress the uncomfortable feeling on the wearer's face.

また、本実施形態のマスク１は、マスク本体３の第２折り返し部３３により、下端縁３ｂ近傍における剛性が増すのでマスク本体３の立体構造の保形性が高まる。したがって、本実施形態のマスク１は、マスク本体３の顔面へのフィット性をより確実に確保し確保し易く、着用者の顔面における違和感をより確実に抑制し易い。   Further, in the mask 1 of the present embodiment, the rigidity in the vicinity of the lower end edge 3b is increased by the second folded portion 33 of the mask body 3, so that the shape retaining property of the three-dimensional structure of the mask body 3 is enhanced. Therefore, the mask 1 of the present embodiment can more reliably secure and ensure the fit of the mask body 3 to the face, and can more easily suppress the uncomfortable feeling on the wearer's face.

また、本実施形態のマスク１は、補助エンボス部３７によりマスク本体３の立体構造の保形性をより一層維持し易い。したがって、本実施形態のマスク１は、マスク本体３の顔面へのフィット性をより確実に確保し易く、着用者の顔面における違和感をより確実に抑制し易い。   Moreover, the mask 1 of this embodiment can maintain the shape retaining property of the three-dimensional structure of the mask main body 3 more easily by the auxiliary embossed portion 37. Therefore, the mask 1 of the present embodiment can more easily ensure the fit of the mask body 3 to the face, and can more reliably suppress the uncomfortable feeling on the wearer's face.
