Fig. 1 is a front view of a mask 10 according to the embodiment of the present invention. As shown in Figure 1, the mask 10 includes: a mask body 11 for covering a part of the user's face (such as the periphery of the mouth and nostrils); ear12.

The mask 10 shown in FIG. 1 is a so-called "pleated type" mask, and the mask body 11 has pleats 16 formed by a plurality of (four in FIG. 1 ) horizontal creases 14 . The pleats 16 are configured to be folded into two approximate Ω shapes in the state shown in FIG. 1 , and when the pleats 16 are unfolded, as shown in FIG. In this way, since the mask main body 11 is pleated in the present embodiment, a space is created around the mouth of the user, and the wearing comfort is excellent even for a long time, and it is difficult to obstruct breathing and conversation.

Fig. 3 is a partially enlarged sectional view (X-X sectional view) of the mask 10 of Fig. 1 . In Fig. 3, the mask main body 11 of the present embodiment has a multilayer structure, and is stacked in this order from the inside surface of the mask 10 (the surface touching the inside of the face) to the outside surface (the surface on the opposite side to the inside surface), A water absorbent sheet 114 and a porous resin film 115 are formed.

The water-absorbent sheet 114 is a sheet that absorbs the water-retaining liquid W and supplies moisture to the user's oral cavity and/or nasal cavity. In addition, the porous resin film 115 is a film that suppresses the water-retaining liquid W in the water-absorbent sheet 114 from seeping out to the outer surface of the mask main body 11 (dehumidification). The mask comprising at least the water-absorbent sheet 114 and the porous resin film 115 has the effects of the present invention as described above, that is, it can effectively prevent the user's oral cavity and/or nasal cavity from drying out, and can prevent the water-retaining liquid W from seeping into the mask main body 11. of the outer surface.

The above-mentioned water-absorbent sheet 114 and porous resin film 115 will be described. The water-absorbent sheet 114 is disposed near the center of the mask 10, and is used to absorb the water-retaining liquid W described later when the mask 10 is used, and to supply moisture to the user's oral cavity and nasal cavity. In order to continuously supply sufficient moisture to the oral cavity and nasal cavity for several hours, it is preferable to be able to hold 5 ml or more of the water-retaining liquid W described later, and it is more preferable to be able to hold 7 ml or more.

As a fiber raw material of the water-absorbent sheet 114, a hydrophilic fiber, and the mixed spinning of a hydrophilic fiber and a synthetic fiber are mentioned, for example. As a hydrophilic fiber, pulp, rayon, cotton, etc. are mentioned, for example. As synthetic fiber, polypropylene, polyethylene, polyester, etc. are mentioned, for example. The fiber material of the water-absorbent sheet 114 may be only hydrophilic fibers, but from the viewpoint of productivity and processability, blending of hydrophilic fibers and synthetic fibers is preferable, and blending of pulp and polypropylene is more preferable. is preferred. The ratio of pulp:polypropylene is preferably 40:60 to 99:1 (mass ratio), more preferably 50:50 to 80:20. As a manufacturing method of such a water-absorbent sheet 114, an airlaid method (airlaid) etc. are mentioned, for example.

The basis weight of the water-absorbent sheet 114 is preferably 80 to 500 g/m ² , more preferably 90 to 300 g/m ² . When the weight per unit area is less than 80 g/m ² , the water retention liquid W cannot be sufficiently retained. In addition, when the weight per unit area exceeds 500 g/m ² , the sheet becomes too thick, which may cause trouble in the manufacture of the mask 10 .

The area of the water-absorbent sheet 114 is preferably 100 to 200 cm ² , more preferably 100 to 150 cm ² , for example, when the mask 10 is used in a three-dimensional shape. In addition, the dimensions of the water-absorbent sheet 114 are, for example, preferably 7 to 20 cm in the horizontal direction and 4 to 12 cm in the vertical direction, and more preferably 10 to 18 cm in the horizontal direction and 5 to 10 cm in the vertical direction. In addition, the area of the water-absorbent sheet 114 can be set smaller than the area of the mask main body 11 . In addition, as the thickness of the water-absorbent sheet 114, in order to keep the water-retaining liquid W described later at 5 ml or more, it is sufficient to be 0.4 mm or more, and it is preferably 0.4 to 0.4 mm from the viewpoint of productivity in mask manufacturing such as pleat processing. 0.9mm, more preferably 0.5-0.8mm.

The water-absorbent sheet 114 can be used as it is in a single layer, but from the viewpoint of durability, a three-layer structure in which a sheet made of the above-mentioned fiber raw material is sandwiched between a sheet or a non-woven fabric is preferable. From the standpoint of safety, it is more preferable to use a three-layer structure in which a sheet made of hydrophilic fibers is used on the outside, a nonwoven fabric made of waterproof fibers is used on the inside (orifice side), and a sheet made of the fiber raw material is sandwiched. .

Examples of the hydrophilic fiber include pulp, rayon, cotton, and the like, and pulp is preferable. Examples of the waterproof fiber include polyethylene, polypropylene, polyester, and the like, and polyester is preferable.

When the outer side is made of a pulp sheet, there are advantages in that it is easy to manufacture and can be easily colored, so it becomes a mark when supplying the water-retaining liquid W. In addition, when the inner side (orifice side) is made of polyester nonwoven fabric, there is an advantage in that the shape retention of the sheet is excellent, and wetting and sticking can be further prevented. As a manufacturing method of such a multilayer water-absorbent sheet 114, it can manufacture by air-laying etc., for example.

The porous resin film 115 is a film for preventing the water-retaining liquid W in the water-absorbent sheet 114 from seeping out to the outer surface of the mask body 11 , and is laminated on the outer side of the water-absorbent sheet 114 .

(d) Anti-humidity: 0g～0.1g

(a) Thickness is the length in the direction perpendicular to the plane of the mask main body 11 from the inside of the mask main body 11 to the outside.

(b) The opening ratio represents the ratio (%) of pores occupying the entire surface of the film. In the case of a film having no pores at all, the opening ratio was 0%.

(c) Penetration time is measured according to EDANA (European Nonwovens Association) 150.5-02, and indicates the time (seconds) for water to come out from under the opening when water hangs down from the opening.

(d) Dehumidification is measured according to EDANA (European Nonwovens Association) 151.3-02, when a film is placed on a water-absorbent sheet impregnated with water, and a load is further applied thereon, the amount of water overflowing ( gram).

The porous resin film 115 can be a commercially available product. For example, a film embossed with an olefin-based thermoplastic resin film such as polyethylene or polypropylene is preferably used, but polyamide-based resins such as polyester or nylon, EVA, etc. can also be used. wait.

The size of the mask main body 11 may be appropriately determined in consideration of the size of the face. For the mask main body 11, for example, a woven fabric or a nonwoven fabric can be used other than the water-absorbent sheet 114 and the porous resin film 115 described above. Preferred are nonwoven fabrics produced by spunbonding, melt blown, thermal bonding or spunlace, and more preferably nonwoven fabrics produced by spunbonding from the viewpoint of shape retention. To constitute the mask main body 11.

In addition, polypropylene or polyethylene is preferable from the viewpoint of productivity, and polypropylene is more preferable from the viewpoint of shape retention.

When forming the mask main body 11 using two or more woven or nonwoven fabrics together with the water-absorbent sheet 114 and the porous resin film 115, they can be formed by, for example, sewing, ultrasonic welding, or heat welding. In addition, at least one pleat (fold) can be formed by creases, whereby the mask main body 11 can be three-dimensionally formed so as to bulge outward, corresponding to various sizes of faces.

In the mask 10 of the present invention, it is preferable to laminate a water-repellent-treated sheet 117 (not shown) inside the water-absorbent sheet 114 . This prevents the water-retaining liquid W from seeping out from the inner surface of the mask body 11, and provides excellent comfort. As a specific example of the waterproof-treated sheet 117, the waterproof nonwoven fabric 112 of FIG. 4 can be mentioned.

As the waterproofed sheet 117, it can usually be prepared by applying a later-described waterproofing agent to the sheet (such as non-woven fabric, gauze, etc.) used in the mask, but it is preferable to use the waterproof polyester fiber as it is. , polypropylene fibers, or non-woven fabrics made of polyethylene fibers.

In the mask 10 of the present invention, it is further preferable that a hydrophilic-treated sheet 118 (not shown) is laminated on the outside of the porous resin film 115 . This prevents damage to the porous resin membrane 115 and improves durability without affecting the supply of the water-retaining liquid W. As a specific example of the hydrophilically treated sheet 118, the hydrophilic nonwoven fabric 116 of FIG. 4 can be mentioned.

As the hydrophilically treated sheet 118, gauze or a hydrophilic non-woven fabric may be used as it is, or a water-repellent non-woven fabric may be used while maintaining hydrophilicity by applying a hydrophilic agent. Examples of the hydrophilic agent include nonionic surfactants such as fatty acid glycerides, alkoxylated alkylphenols, polyoxyalkylene fatty acid esters, alkyl polyoxyethylene alcohols, fatty acid amides, fatty acid salts, alkyl Surfactants such as sulfate ester salts, alkylbenzenesulfonates, alkylnaphthalenesulfonates, dialkylsulfosuccinates, etc.

The water-retaining liquid W held in the water-absorbent sheet 114 is not particularly limited as long as it is safe for the human body and effectively prevents the user's oral cavity and/or nasal cavity from drying out. The water-retaining liquid W may be water, or may contain water as a main component and may contain components other than water.

Examples of components other than water include preservatives such as methylparaben, propylparaben, or phenoxyethanol, humectants such as hyaluronate or betaine, plant extracts, xanthan gum, hydroxy Propylmethylcellulose (HPMC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), water-soluble thickeners such as agar, guar gum or carrageenan, spices such as eucalyptus or mint, will Perfume-soluble surfactants (for example, nonionic surfactants, amphoteric surfactants, or anionic surfactants) and the like.

In order to impart water repellency to the nonwoven fabric, a method of adding and applying a water repellent to the nonwoven fabric may be mentioned. As the water repellent, known materials can be used as long as they are highly safe to the human body, but it is more preferable to use a material that is less irritating to the skin. In addition, since the nonwoven fabric made of polyester fibers, polypropylene fibers, or polyethylene fibers has water repellency, it can be used as it is without water repellent treatment.

As a specific waterproofing agent, for example, a fluorine-based waterproofing agent containing a fluorine-based resin, a silicon-based waterproofing agent containing a silicone-based resin, a paraffin-based waterproofing agent, and a wax-based waterproofing agent, etc., are preferably used. agent.
