Abstract

PURPOSE: To obtain a material for mask free from stickiness and stuffy feeling in use and exhibiting excellent comfortableness by laminating plural specific nonwoven fabric sheets. CONSTITUTION: This nonwoven fabric material for mask to enable easy breathing and speach is produced by laminating a nonwoven fabric produced from a thermoplastic synthetic fiber by conventional method on one surface of a mask material, laminating a nonwoven fabric made of a cellulosic fiber on the other face and/or as an intermediate layer of the material and integrating the layers e.g. by water-jet stream, needle punching, etc. The thermoplastic synthetic fiber is preferably a conjugate synthetic fiber containing synthetic fibers such as polyolefin fiber, polyester fiber and polyamide fiber in a side-by- side form, a sheath-core form, a sea-island form, etc.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a mask material.

[0002]

2. Description of the Related Art Conventionally, various masks have been widely used for hay fever, medical workers, clean room workers, dust workers, etc., and cotton gauze or electret fiber sheet is applied to the part that contacts the mouth. As the form of the abutting part using a synthetic fiber non-woven fabric or the like, a flat sheet or a pleated form is added, and further, there is a space between the mouth and the mask in order to facilitate conversation or prevent breathing. There is something that is thermoformed into a bowl shape so that it can be done.

Further, a string-like object is attached for hanging on the ear, or as shown in FIG. 2, the ear-hanging portions 2 at both ends of the sheet-like object 4 of a predetermined size are punched out (industrial, the sheet is used). It is known to form a ring-shaped portion at both ends and stack the ring-shaped portion on the ear, etc. Conventional masks generally have stickiness and stuffiness during use, and the non-woven fabric mask, which is the lowest cost mask with only punched out parts corresponding to the ears, is particularly sticky and stuffiness during use. It lacked comfort.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a mask material which can improve comfort.

[0005]

The present invention is a mask material in which a plurality of nonwoven fabrics are laminated, one side of the mask material is a thermoplastic synthetic fiber nonwoven fabric, and the other surface and / or the intermediate surface. A material for a mask, wherein the layer is a cellulosic fiber non-woven fabric. The thermoplastic synthetic fiber nonwoven fabric in the present invention is composed of one or more kinds of synthetic fibers such as polyolefin-based, polyester-based, polyamide-based, etc., and a nonwoven fabric manufactured by a known manufacturing method such as web and spunlace, spunbond method. Includes.

For example, a heat-fusible fibrous web (generally having a melting point of 96 ° C. to 200 ° C., a single yarn denier of 0.5 to 3)
A 2-denier resin is used, for example, a single component type consisting of polyethylene, polypropylene, polyester (homopolymer amorphous, copolymer amorphous), polyolefin (core polypropylene, sheath polyethylene or polypropylene. The cross section of the fiber is a side-by-side or sheath-core structure, the melting point is 96 ° C to 142 ° C), and the fiber cross section is made of polyester (core polyethylene terephthalate, sheath polyethylene terephthalate, polyethylene or polypropylene, nylon, ethylene vinyl acetate, cationic dyeable polyester). Is a sea-island, side-by-side or sheath-core structure, melting point: 96 ° C-190 ° C), nylon-based, PVC-based composite component type, but melting point is 96
℃ -150 ℃, 0.5-3 denier single-filament denier composite component type heat-fusible fiber is preferable from the sense of volume, texture, and touch), melt-blown non-woven fabric, etc., single-denier 1 denier or less The ultrafine fiber non-woven fabric, electret fiber non-woven fabric, flash-spun non-woven fabric and the like are included.

Further, these non-woven fabrics may be used in combination. For example, for pollinosis and the like, a melt blown non-woven fabric or an electret fiber is interposed between a normal non-woven fabric such as polyester spun bond and a non-woven fabric of cellulosic fiber. It is preferable to stack them. The cellulosic fiber non-woven fabric in the present invention means regenerated cellulosic fibers such as pulp, cotton, cupra, viscose rayon, polynosic rayon and the like, LYOCELL; .584-591
(Corresponding to Tencel, trade name of Courtles, Inc. described in (1992)) or the like, and includes a web and a nonwoven fabric produced by a known production method such as a spunlace or spunbond method. Further, these non-woven fabrics may be used in combination.

It should be noted that thermoplastic synthetic fibers other than cellulosic fibers and the like may be mixed in the cellulosic fiber nonwoven fabric within a range not impairing the object of the present invention, and usually 5
0% or less, preferably 30% or less. The basis weight of the non-woven fabric used for the mask material of the present invention is 10 to 100 g /
m ² , preferably 15 to 80 g / m ^{2 is} good, 10 g /
When it is less than m ² , strength is poor, and when it exceeds 100 g / m ² , comfort such as stuffiness may be impaired.

The material for a mask of the present invention is a laminate of such a thermoplastic synthetic fiber nonwoven fabric and a cellulosic fiber nonwoven fabric. The form of lamination is two layers of a thermoplastic synthetic fiber nonwoven fabric and a cellulose fiber nonwoven fabric. 4 layers, such as 3 layers with a layer of cellulosic fiber non-woven between thermoplastic synthetic fiber non-woven fabric as the basis and 4 layers by laminating 2 layers with each other as desired The above multi-layer structure may be used, but as the thickness of the mask increases as the number of layers increases, comfort such as stuffiness is impaired and cost is increased, so about five layers are preferable. ~200g / m ² preferably 50~100g /
m ² is good.

For laminating the non-woven fabric, known means such as a pouring flow by a water jet, needle punching, thermocompression bonding, etc. are used. As a method and form for forming the mask material of the present invention into a mask, known methods and forms can be used. In particular, the mask material of the present invention is composed of two mask materials 1a and 1b which are cut into a predetermined shape as shown in FIG. 1 so that the thermoplastic synthetic fiber nonwoven fabric is arranged inside.
And punching out the portion 2 to be applied to the ear, then cutting it into a convex shape or a curved shape, and thermocompressing the portion 3 corresponding to the central portion of the mask with a predetermined width (usually about 1 to 6 mm) ( For example, those that have been thermocompression bonded with a high frequency welder, etc.
A space is created between the mouth and the mask, which not only reduces the stickiness and stuffiness at the low cost, but also facilitates conversation and eliminates breathlessness, further improving comfort.

The masking material of the present invention may, if desired,
A pattern may be provided by coloring or embossing. By using the thermoplastic synthetic fiber nonwoven fabric side of the mask material of the present invention in contact with the mouth, it is possible to obtain a comfortable mask with less stickiness and stuffiness. Further, one surface of the nonwoven fabric to be laminated, and preferably the other surface and / or the intermediate layer is also excellent in strength when it is also composed of long fibers,
In particular, it is useful for a type of mask that punches out the part to be worn on the ear, and the ring-shaped part may be cut during wearing or during use due to insufficient strength with only a short-fiber nonwoven fabric.
