Description

マスクmask
 本発明は、着用者の顔に装着されるマスクの構造技術に関する。 The present invention relates to a structure technology of a mask to be worn on a wearer's face.
 従来、例えば、下記特許文献には、メントールを含有させた微多孔性中空繊維からなる繊維状物質を有するマスクが開示されている。 Conventionally, for example, the following patent document discloses a mask having a fibrous substance composed of microporous hollow fibers containing menthol.
特開昭63-209666号公報JP-A 63-209666
 ここで、マスクの捕集性(例えば、バクテリア飛沫ろ過効率BFE)を高めるためには、マスクの外側に配置される外側不織布シートの通気性を低くする(通気抵抗を大きくする)必要がある。一方、外側不織布シートの通気性を低くすると、着用者は息苦しさを感じる。このため、マスクの捕集性と通気性の両方を高いレベルで両立させることができる外側不織布シートの開発が進められている。本発明者らは、外側不織布シートの開発と並行して、着用者側に配置される内側不織布シートについても検討した結果、内側不織布シートの通気性を、外側不織布シートの通気性より高めることにより、香料から発生する香りが着用者の鼻孔粘膜に達し易くなり、息苦しさを感じ難くなることを見出した。
 したがって、本願発明は、マスクの捕集性と通気性を高いレベルで両立させることができる新規な技術を提供することを目的とする。
Here, in order to improve the collection property of the mask (for example, bacterial splash filtration efficiency BFE), it is necessary to reduce the air permeability of the outer nonwoven fabric sheet arranged outside the mask (increase the air resistance). On the other hand, if the air permeability of the outer nonwoven fabric sheet is lowered, the wearer feels breathlessness. For this reason, development of the outer nonwoven fabric sheet which can make both the collection property and breathability of a mask compatible at a high level is advanced. In parallel with the development of the outer nonwoven fabric sheet, the present inventors also examined the inner nonwoven fabric sheet disposed on the wearer side. As a result, the breathability of the inner nonwoven fabric sheet was increased more than the breathability of the outer nonwoven fabric sheet. The present inventors have found that the fragrance generated from the fragrance can easily reach the wearer's nostril mucosa, making it difficult to feel breathlessness.
Therefore, an object of the present invention is to provide a novel technique capable of achieving both the trapping property and the air permeability of the mask at a high level.
 本発明は、着用者の少なくとも口と鼻を覆うマスク本体部を備えている。なお、一般的には、マスク本体部を装着する装着部材が設けられる。装着部材としては、例えば、着用者の耳に引っ掛けられる耳掛け部、着用者の頭部に掛け回されるヘッドバンド部等が用いられる。マスク本体部は、内側不織布シートと、外側不織布シートと、内側不織布シートと外側不織布シートの間に設けられている香料含有不織布シートを有し、マスク着用時に、内側不織布シートが着用者側に配置されるように積層されている。
 香料含有不織布シートは、香料を含有するマイクロカプセルを含んでいる。マイクロカプセルとしては、手でたたく、手でもむ等の外力を加えることによって容易に破壊することができるカプセルが用いられる。香料としては、種々の香料を用いることができる。例えば、鼻炎、アレルギー等によるくしゃみ、鼻汁、鼻づまりに対して有効であるとされているメントールを用いることができる。
 そして、内側不織布シートの通気性が、外側不織布シートの通気性より高く(通気抵抗が小さく)なるように設定されている。なお、外側不織布シートの通気性は、マスクの捕集性が低下しない範囲内で高められる。
 本発明では、内側不織布シートの通気性が外側不織布シートの通気性より高く設定されているため、香料含有不織布シートに含まれているマイクロカプセルの破壊によって発生する香りが、着用者の鼻孔粘膜に達し易くなり、着用者は息苦しさを感じ難くなる。
The present invention includes a mask body that covers at least the mouth and nose of the wearer. In general, a mounting member for mounting the mask main body is provided. As the mounting member, for example, an ear hook portion that is hooked on the wearer's ear, a headband portion that is hung around the wearer's head, or the like is used. The mask body has an inner nonwoven fabric sheet, an outer nonwoven fabric sheet, and a fragrance-containing nonwoven fabric sheet provided between the inner nonwoven fabric sheet and the outer nonwoven fabric sheet, and the inner nonwoven fabric sheet is arranged on the wearer side when the mask is worn. Are stacked as shown.
The perfume-containing non-woven sheet includes microcapsules containing a perfume. As the microcapsule, a capsule that can be easily broken by applying an external force such as tapping with a hand or peeling with a hand is used. Various fragrance | flavors can be used as a fragrance | flavor. For example, menthol, which is effective for rhinitis, sneezing due to allergies, nasal discharge, and nasal congestion, can be used.
And the air permeability of an inner side nonwoven fabric sheet is set so that it may be higher than the air permeability of an outer side nonwoven fabric sheet (air permeability resistance is small). In addition, the air permeability of the outer nonwoven fabric sheet is enhanced within a range where the trapping property of the mask does not deteriorate.
In the present invention, since the breathability of the inner nonwoven fabric sheet is set higher than the breathability of the outer nonwoven fabric sheet, the scent generated by the breakage of the microcapsules contained in the fragrance-containing nonwoven fabric sheet is in the nostril mucosa of the wearer. It becomes easier to reach and the wearer is less likely to feel stuffy.
 本発明の異なる形態では、外側不織布シートは、平均繊維径が1~3μm、目付が2~5g/mであり、エレクトレット化された不織布シートとして構成されている。
 本形態では、マスクの捕集性および通気性を高いレベルで両立させたマスクを容易に得ることができる。
In a different form of the present invention, the outer nonwoven fabric sheet has an average fiber diameter of 1 to 3 μm and a basis weight of 2 to 5 g / m 2 and is configured as an electret nonwoven fabric sheet.
In this embodiment, it is possible to easily obtain a mask in which the mask collecting property and air permeability are compatible at a high level.
 本発明の他の異なる形態では、内側不織布シートと香料含有不織布シートとの間の摩擦抵抗が、内側不織布シートと外側不織布シートとの間の摩擦抵抗より小さい。摩擦抵抗は、例えば、内側不織布シートに含まれる素材等を選択することによって変化させることができる。
 本形態では、手でもむ等によってマスク本体部に外力を加えた時に、香料含有不織布シートに含まれているマイクロカプセルのうち、内側不織布シートと面する領域に存在するマイクロカプセルが破壊され易くなる。
In another different form of the invention, the frictional resistance between the inner nonwoven sheet and the perfume-containing nonwoven sheet is less than the frictional resistance between the inner nonwoven sheet and the outer nonwoven sheet. The frictional resistance can be changed, for example, by selecting a material included in the inner nonwoven fabric sheet.
In this embodiment, when an external force is applied to the mask body by hand or the like, among the microcapsules contained in the fragrance-containing nonwoven fabric sheet, the microcapsules existing in the region facing the inner nonwoven fabric sheet are easily destroyed. .
 本発明の他の異なる形態では、香料含有不織布シートは、不織布シートと、不織布シートの、内側不織布シートと面する領域に塗布されている、香料を含有するマイクロカプセルにより構成されている。
 本形態では、マイクロカプセルが、内側不織布シートと面する領域に配置されているため、香料から発生する香りが着用者の鼻孔粘膜に達し易くなる。
 なお、本形態の構成と、前述した、内側不織布シートと香料含有不織布シートとの間の摩擦抵抗が、内側不織布シートと外側不織布シートとの間の摩擦抵抗より小さい構成とを組み合わせることにより、より優位な効果が発生する。すなわち、マイクロカプセルを破壊し易くすることができるとともに、破壊し易い位置にマイクロカプセルを配置することができる。
In another different form of the present invention, the perfume-containing non-woven sheet is composed of a non-woven sheet and a microcapsule containing a perfume that is applied to a region of the non-woven sheet facing the inner non-woven sheet.
In this embodiment, since the microcapsules are arranged in the region facing the inner nonwoven fabric sheet, the scent generated from the fragrance easily reaches the wearer's nostril mucosa.
In addition, by combining the configuration of this embodiment and the configuration described above, the friction resistance between the inner nonwoven fabric sheet and the fragrance-containing nonwoven fabric sheet is smaller than the friction resistance between the inner nonwoven fabric sheet and the outer nonwoven fabric sheet, An advantageous effect occurs. That is, the microcapsule can be easily broken and the microcapsule can be arranged at a position where the microcapsule is easily broken.

The electretization treatment of the coated nonwoven fabric sheet 60 can be appropriately performed together with the outer nonwoven fabric sheet 50 or independently of the outer nonwoven fabric sheet 50. The coated nonwoven fabric sheet 60 is typically a spunlace nonwoven fabric sheet produced by a spunlace method, an air-through nonwoven fabric sheet produced by an air-through method, a spunbond nonwoven fabric sheet produced by a spunbond method, or a needle punch method. The manufactured needle punched nonwoven fabric sheet can be used, and it is preferable to use one having an average fiber diameter of 15 to 30 μm and a basis weight of 18 to 50 g / m 2 . The coated nonwoven fabric sheet 60 in this case is obtained by electretizing a nonwoven fabric sheet containing at least polypropylene fibers, and the nonwoven fabric sheet may be composed only of polypropylene fibers, or may be further fibers in addition to polypropylene fibers. For example, you may comprise as what added the polyethylene fiber.
 内側不織布シート30としては、外側不織布シート50および被覆不織布シート60とは異なり、エレクトレット化されていない不織布シートが用いられる。内側織布シート30として、典型的にはポリエチレンテレフタレート繊維及びポリエチレン繊維を含み、加圧ロールによるポイントボンド加工がなされた低密度のポイントボンド不織布シート(例えば、繊維径が15.412μm、目付が30g/m、通気抵抗が0.0533kPa・s/m、厚みないし嵩が0.20mm以上の不織布シート)を用いるのが好ましい。着用者の顔面(肌)に直に触れるこのような構成の内側不織布シート30は、肌触りの良い不織布シートとして好適に用いられる。なお、必要に応じては、内側不織布シート30として、エレクトレット化されたポリプロピレン製の不織布シートを用いることもできる。 As the inner nonwoven fabric sheet 30, unlike the outer nonwoven fabric sheet 50 and the coated nonwoven fabric sheet 60, a nonwoven fabric sheet that is not electretized is used. The inner woven fabric sheet 30 typically includes a polyethylene terephthalate fiber and a polyethylene fiber, and is a low-density point-bond nonwoven fabric sheet that has been point-bonded by a pressure roll (for example, a fiber diameter of 15.412 μm and a basis weight of 30 g). / M 2 , a non-woven sheet having a ventilation resistance of 0.0533 kPa · s / m and a thickness or bulk of 0.20 mm or more.
