The present invention relates to a mask.

In recent years, the number of patients with various allergic symptoms such as pollen is increasing. Infectious diseases caused by various viruses are prevalent every year. An effective means for such allergic symptoms and infectious diseases includes wearing a mask.
The mask is worn on the human face and covers the nose and mouth to prevent minute airborne debris from being taken into the body and to prevent the mouth and nose secretions from being scattered around. To. Therefore, it is possible to prevent pollen and the like from being taken into the body, and even if an infectious disease should occur, the influence on the surroundings can be minimized. Wearing masks is becoming etiquette, especially in public places, when infectious diseases are endemic.
Such masks include disposable masks and masks that can be used repeatedly by washing. Disposable masks are hygienic and therefore very convenient to use for a period of time. However, it is uneconomical to use a new mask every day in situations where wearing a mask is becoming etiquette as described above.

Such masks that can be used repeatedly have been conventionally known.
Patent Document 1 discloses a sanitary mask in which a plurality of silk fabrics made of shrink-treated raw silk, which have good hygroscopicity and are soft to the touch, are laminated and have embroidery on the front surface. Has been done. Specifically, by preparing a silk fabric that is three times as wide and four times as long as the mask, fold it so that it becomes triple in the width direction, and then fold it so that it becomes quadruple in the length direction. A mask material made of multiple fabrics is molded. That is, a mask having a 12-layer structure is disclosed.
Patent Document 2 describes a face mask having a three-layer structure consisting mainly of a mask, an auxiliary cloth, and a back surface mask, and has a front surface extending vertically in the center of the mask in order to form a raised portion which is a three-dimensional shape of the mask. Those provided with a central suture portion are disclosed. This front central suture gives the mask a three-dimensional shape, preventing the mask from sticking to the nose and lips and preventing suffocation, and also preventing the color transfer of the cosmetic to the mask body during makeup. It is possible to create a ridge that is a three-dimensional shape for this purpose.

Japanese Unexamined Patent Publication No. 2000-116804 Utility model registration No. 3191345

However, in the case of the sanitary mask of Patent Document 1, although the left and right ends of the mask are sewn together to be integrated, the surfaces of each layer are independent, so that each layer shrinks independently when washed, or the surfaces are separated from each other. The shape of the mask may change due to misalignment, or the woven fabric may fray and be damaged due to friction between the surfaces. Since the face mask of Patent Document 2 has a central suture portion, the washing durability is high, but since the central suture portion also appears on the front surface, the degree of freedom in design as a mask is low.
An object of the present invention is to provide a mask having high washing durability and a high degree of freedom in front design.

The mask of the present invention is a mask having a multi-layer structure including an outer layer, an intermediate layer and an inner layer. The outer layer and the inner layer are cloth products other than the non-woven fabric, and the intermediate layer is a non-woven fabric and the outer layer. And the inner layer forms a bag body in which the left and right edges and the upper and lower edges are closed, and the left and right edges of the intermediate layer are connected to the outer layer and the inner layer, and the middle layer and the middle layer except for the outer layer are formed. The inner layer is characterized in that it is bonded in the central region. Here, as means for closing the edges of the outer layer and the inner layer, sewing or adhesion or welding of fibers to each other can be mentioned. Alternatively, if the outer and inner layers are formed by folding a piece of fabric, the folds are also included. Further, as a means for connecting the left and right edges of the intermediate layer and the left and right edges of the outer layer and the inner layer, sewing or adhesion or welding of fibers may be mentioned. Further, as a means for connecting the intermediate layer and the inner layer in the central region, sewing or adhesion or welding of fibers can be mentioned.
In the mask of the present invention, since the intermediate layer and the inner layer are bonded in the central region except for the outer layer, the unity between the intermediate layer and the inner layer is maintained even after washing, and the shape as a mask can be maintained. .. And the degree of freedom in designing the front (the surface of the outer layer) is high.

It is preferable that the mask of the present invention is provided with an inner seam in which an intermediate layer and an inner layer are sewn in the central region. When the inner stitch is provided in this way, breathability can be ensured. The inner stitch is preferably composed of at least two stitches. In particular, it is preferable that at least two stitches intersect. As a result, it is possible to further suppress deformation in which the inner layer and the intermediate layer are independent due to washing.
Here, the "seam" is a sewn linear thread that appears on the inner layer side when the inner layer and the intermediate layer are sewn with a thread.

The mask of the present invention preferably has box pleats formed on the surface thereof by bending the outer layer, the intermediate layer and the inner layer. As a result, when using the mask, the three-dimensional shape of the mask can be secured. Further, since the outer layer, the intermediate layer and the inner layer are bent, the integrity is improved and each layer is less likely to shift when washed. When box pleats are formed on the front surface, valley folds are formed on the inner layer, and the inner layer is liable to shrink or deform during washing. However, the inner stitches connecting the intermediate layer and the inner layer can more efficiently prevent the inner layer from shrinking or deforming.

It is preferable that the mask of the present invention has the outer layer made of a patterned woven fabric. In particular, it is preferable that the woven fabric is a crest fabric produced by a jacquard loom. In this case, since the inner stitch does not appear on the outer layer, it is possible to design with a free pattern.

The mask of the present invention preferably has a basis weight of 50 g / m2 or more and a thickness of the nonwoven fabric of 0.5 mm or more. As described above, the nonwoven fabric in which the intermediate layer has a predetermined basis weight and thickness has high washing durability. By connecting the left and right edges of the intermediate layer having high washing durability to the left and right edges of the inner layer and the outer layer, the intermediate layer prevents the inner layer and the outer layer from shrinking due to washing, and the washing durability is further improved.

In the mask of the present invention, the intermediate layer and the inner layer are bonded in the central region except for the outer layer, so that the mask has high washing durability and a high degree of freedom in frontal design.

1a, 1b, and 1c are perspective views, rear views, and partial cross-sectional schematic views showing an outline of the usage state of the mask of the present invention, respectively. 2a and 2b are front views and rear views showing an unused state of the mask of the present invention, respectively. FIG. 3a is a schematic view in which a part of the upper folding portion and the lower folding portion of FIG. 2b is cut out, and FIG. 3b is an explanatory schematic view showing a central region. 4a and 4b are back views showing other embodiments.

The mask 1 of FIG. 1a includes a mask main body 10 and ear hook portions 11 provided on the left and right sides thereof. Box pleats 13 are formed on the surface (outside) of the mask body 10. As shown in FIG. 1b, the mask main body 10 has a three-layer structure including an outer layer 21, an intermediate layer 22, and an inner layer 23. The outer layer 21 and the inner layer 23 are made of a cloth product other than a non-woven fabric, and the intermediate layer 22 is made of a non-woven fabric. .. Then, as shown in FIGS. 1b and 1c, an inner stitch 30 for connecting the intermediate layer 22 and the inner layer 22 is provided in the central region of the mask main body 10 except for the outer layer 21.

As shown in FIGS. 2a and 2b, the mask main body 10 is a rectangular shape in which three outer layers 21, an intermediate layer 22 and an inner layer 23 cut into a rectangular shape are stacked, and the left and right edges and the upper and lower edges thereof are sewn. .. The reference numerals 12a, 12b, 12c, and 12d each represent a stitch that penetrates all three layers. That is, the upper and lower edges and the left and right edges of the outer layer 21, the intermediate layer 22, and the inner layer 23 are connected and integrated by these stitches. By these stitches, the left and right edges and the upper and lower edges of the outer layer 21 and the inner layer 23 are closed to form a bag body, and the left and right edges and the upper and lower edges of the intermediate layer 22 are connected to the outer layer 21 and the inner layer 23. ..
The ear hooks 11 are connected by the stitches 12a and 12b on the left and right edges. Further, below the seam 12c on the upper edge, a wire seam 14a extending to the left and right in parallel with the seam 12c on the upper edge is provided. The wire seam 14a also connects the upper edge of the intermediate layer 22 to the outer layer 21 and the inner layer 23.

Box pleats 13 (box folds) are formed in the central portion of the surface (FIG. 2a) of the mask body 10. In other words, on the upper side of the central portion of the back surface of the mask body (FIG. 2b), the upper folding portion 13a extending in the left-right direction and formed downward is formed, and the lower side of the central portion of the inner surface of the mask body 10. A lower folding portion 13b extending in the left-right direction and formed upward is formed therein. The upper folding portion 13a and the lower folding portion 13b are formed by folding the inner layer in a valley. The upper folding portion 13a and the lower folding portion 13b are located in the center so that the ends do not overlap, and cover the back surface of the pleats 13c (see FIGS. 1c and 3a). The box pleats 13 are formed by folding all three layers.

On the back surface 13c of the pleats, as shown in FIGS. 3a and 1c, an inner seam 30 is formed in which the inner layer 23 and the central region substantially in the middle of the intermediate layer 22 are sewn and joined together, except for the outer layer 21. .. The inner stitch 30 is provided with two stitches in a cross shape. Here, the stitch is a stitch of a sewn linear thread that appears on the inner layer side when the inner layer and the intermediate layer are sewn with a thread. By integrating the inner layer 23 with the intermediate layer 22 in this way, it is possible to suppress the displacement of the intermediate layer 22 and the inner layer 23. Since it is a seam, it does not affect the air permeability.

The inner stitch 30 is preferably composed of at least two stitches. In particular, it is preferable that at least two stitches intersect. It is preferable that the inner stitch 30 is independent of the stitches (reference numerals 12a to 12d) at the left and right ends and the upper and lower ends without being continuous.
The central region means that the region surrounded by the ends of the stitches constituting the inner stitch 30 is near the center of the mask. For example, as shown in FIG. 3b, it means that the region 35 (dotted line) surrounding the inner stitch 30 includes the center O of the mask. As shown in FIG. 3b, the center of the region 35 of the inner stitch 30 and the center O of the mask do not have to coincide with each other.

Returning to FIG. 2, a nose wire 14 is embedded in the upper part of the mask body 10 along the left-right direction. The nose wire 14 is provided between the inner layer 23 and the outer layer 21 in FIG. 1b. It may be on the outside or inside of the intermediate layer 22. Further, the non-woven fabric of the intermediate layer 22 may be slightly longer in the vertical direction than the outer layer 21 and the inner layer 23, the upper portion may be folded back to the vicinity of the wire seam 14a, and the nose wire 14 may be inserted into the folded portion. Further, the intermediate layer 22 may be slightly shorter in the vertical direction than the inner layer 23 and the outer layer 21, and the nose wire 14 may be provided above the intermediate layer 22. In this case, the upper edge of the intermediate layer 22 may be connected to the outer layer 21 and the inner layer 23 at the wire seam 14a, or the upper edge of the intermediate layer 22 may not be fixed.

The cloth products other than the non-woven fabric constituting the inner layer 23 and the outer layer 21 refer to a woven fabric, a knitted fabric, or the like.
The woven fabric is a cloth product in which warp and weft are combined, and examples thereof include plain weave, twill weave, satin weave, and crest woven fabric in which they are combined. In particular, it is preferably a crest fabric woven by a jacquard loom. Further, it is preferable that the two woven fabrics are integrated into a double woven fabric. The double woven fabric is integrated by partially incorporating the weft (or warp) of one woven fabric into the structure of the other woven fabric, so that it does not easily become crumpled even when washed and has high washing durability. high. Further, the double woven fabric is softer to the touch than a single woven fabric, and can give a profound feeling to the entire mask and enhance the decorativeness.
Knitting is a cloth product made by knitting threads.
As described above, since the inner layer 23 and the outer layer 21 are mainly composed of cloth products other than the non-woven fabric, the air permeability is high.

Examples of threads (materials) used for textiles and knitting include vegetable fibers such as hemp and cotton, natural fibers of animal fibers such as silk and wool, and synthetic fibers such as polyester such as nylon, acrylic and polyethylene terephthalate. By making it made of silk, it is less irritating to the skin to be worn and feels good on the skin. Further, since the silk thread has good hygroscopicity, the inside of the mask can be kept within a predetermined humidity range. Further, by washing, the silk thread absorbs an appropriate amount of water, and a more supple feel is obtained when the silk thread is worn. Therefore, it is particularly preferable that the inner layer is made of silk. On the other hand, by using linen, the air permeability can be increased and a refreshing feeling can be obtained. The outer layer and the inner layer may be made of the same material or may be made of different materials. The combination (outer layer / inner layer) is not particularly limited, and examples thereof include hemp / hemp, silk / silk, and hemp / silk.

The intermediate layer 22 is made of a non-woven fabric that acts as a filter for adsorbing fine suspended matter such as pollen and viruses. In particular, it is preferable that the basis weight is 50 g / m2 or more and the thickness is 0.5 mm or more. With such a configuration, fraying and shrinkage of each fiber are less likely to occur due to washing or the like. That is, since the mask main body 10 is integrated by connecting the left and right edges and the upper and lower edges of the outer layer 21, the intermediate layer 22, and the inner layer 23, the intermediate layer 22 prevents the inner layer and the outer layer from shrinking due to washing or the like. Since the intermediate layer 22 is more strongly bonded to the inner layer 23 by the inner seam 30, the shrinkage of the inner layer is further prevented.
Further, the non-woven fabric of the intermediate layer 22 is embossed by being strongly pressed by a stamp having a predetermined shape and heated. By applying the embossing in this way, the washing durability is further improved.

The lower limit of the basis weight of the nonwoven fabric is 50 g / m2 or more, preferably 60 g / m2 or more, more preferably 70 g / m2 or more, and particularly preferably 80 g / m2 or more. If it is less than 50 g / m2, the washing durability of the mask body 10 is lowered. On the other hand, the upper limit of the basis weight is 200 g / m2 or less, preferably 150 g / m2 or less, more preferably 120 g / m2 or less, and particularly 110 g / m2 or less. If it is larger than 200 g / m2, the air permeability will decrease.
The thickness of the nonwoven fabric is 0.5 mm or more, preferably 0.6 mm or more, more preferably 0.7 mm or more, and particularly preferably 0.75 mm or more. If the thickness of the non-woven fabric is thinner than 0.5 mm, the washing durability of the mask body 10 is lowered. On the other hand, the upper limit of the thickness of the nonwoven fabric is 5 mm or less, preferably 3 mm or less, more preferably 2 mm or less, and particularly preferably 1.5 mm or less.
The fineness of the non-woven fabric is 0.5 to 10 denier, preferably 1 to 7 denier, and particularly preferably 2 to 5 denier. If it is larger than 10 denier, the filter effect is reduced. It should be noted that a material smaller than 0.5 denier is not realistic as a material for a mask.

Examples of the fiber material of the non-woven fabric include polyolefins such as polyethylene and polypropylene, nylon and the like. One or several of these may be mixed. Particularly, polypropylene is preferable. As the material of the non-woven fabric, it is preferable to use a material different from that of the cloth product of the inner layer and / or the outer layer.
Examples of the method for producing a non-woven fabric include a chemical bond method, a thermal bond method, a needle punch method, a spunlace method, a chemical spunlace method, a spunbond method, a melt blow method, and an airlaid method. Among these, a non-woven fabric directly connected to a spinning yarn such as a spunbond method and a melt blow method is preferable, and a non-woven fabric by a spunbond method is particularly preferable. Since the non-woven fabric directly connected to the spinning yarn uses continuous long fibers as the non-woven fabric, the fibers are less likely to fray when washed.
As the non-woven fabric, one or a plurality of non-woven fabrics may be stacked. When a plurality of nonwoven fabrics are stacked, at least one of them may satisfy the above-mentioned basis weight and thickness conditions, or the basis weight, thickness and fineness conditions. For example, it is conceivable to use a non-woven fabric having a strong antibacterial and antiviral effect on top of the above-mentioned non-woven fabric having a basis weight and a thickness.

The embossing is performed by providing a recess in the entire non-woven fabric. In particular, it is preferable to provide the recesses evenly. The area of such a recess (pushing die) is 5 mm2 or less, preferably 3 mm2 or less, and particularly preferably 1 mm2 or less. By finely providing the recess 25a, the air is well ventilated and the adhesion of bacteria and the like is also good. On the other hand, it is not realistic that it is smaller than 0.2 mm2.
The upper limit of the total area of the recesses with respect to the total area of the intermediate layer 22 is 40% or less, preferably 30% or less, and particularly preferably 25% or less. If it is larger than 40%, the air permeability will be poor. On the other hand, the lower limit is 5% or more, preferably 10% or more, and particularly preferably 15% or more. If it is less than 5%, the washing durability will be low.

Examples of the nose wire 14 include a linear object or a band-shaped object having shape memory. Examples of the material of such a linear object include metal, synthetic resin, vulcanized fiber and the like. Examples of the metal include aluminum and iron. Examples of the synthetic resin include polyolefins such as polyethylene and polypropylene, and polyesters such as polyethylene terephthalate. Vulcanized fiber is a chemically processed compressed fiber. For example, wood pulp and cellulose fibers made from cotton are compressed and chemically treated (particularly, immersed in a zinc chloride solution). Vulcanized fiber has high water resistance and is suitable for mask materials that are used repeatedly. Vulcanized fiber made of cellulose fiber is also environmentally friendly.

As described above, the mask 10 has a structure in which the outer layer 21, the intermediate layer 22, and the inner layer 23 are integrated, so that the mask 10 is not easily deformed by washing. However, since the mask main body 10 further connects the inner layer 23 and the intermediate layer 22 by the inner seam 30, the washing durability is further higher. In particular, a mask having box pleats formed on its surface is easily deformed by washing or the like because the inner layer is valley-folded, and its effect is remarkable. On the other hand, in the mask 10, since the inner seam 30 does not appear on the outer layer 21, the degree of freedom in designing the front surface of the mask (the surface of the outer layer) is high. In particular, when the outer layer is a crest fabric, the effect is remarkable.

Next, an example of a mask manufacturing method will be described.
First, prepare fabric products for the inner and outer layers. Prepare the inner layer and the outer layer independently. However, if the inner and outer layers have the same structure, one piece of fabric may be molded and folded in half. For example, in a loom such as a jacquard loom, a double woven fabric is formed from silk thread and cut into twice the size of the mask body 10, specifically, twice in the height direction, and the cut double woven fabric is cut up and down. For example, folding it in half. In this case, the upper edge stitch 12c or the lower edge stitch 12d is omitted to form a crease. The crease is preferably the upper edge.
Next, the intermediate layer 22 is prepared. Specifically, a nonwoven fabric that is longer in the vertical direction than the outer layer 21 and the inner layer 23 is prepared, and the upper portion thereof is folded back to the vicinity of the wire seam 14a to prepare the intermediate layer 22. As a result, the intermediate layer 22 having a tubular portion at the upper portion is formed. At this time, it is preferable to sew the folded end portion in order to fix the tubular portion.
Next, the nose wire 14 is inserted into the tubular portion of the intermediate layer 22.
Then, the inner layer 23 and the intermediate layer 22 into which the nose wire 14 is inserted are overlapped with each other, and the inner stitch 30 is inserted.
Then, the outer layer, the intermediate layer, and the upper and lower edges of the outer layer are sewn and integrated. That is, the upper and lower edge seams 12c and 12d are inserted to fix the three layers. When the inner and outer layers are folded, the lower edge 12d or the upper edge 12c is sewn. The edges are woven and sewn so that the cut edges are not exposed.
After integrating the three layers, the entire three layers are bent to form a pleated box.
Finally, the ear hook 11 is placed at predetermined positions on the left and right edges of the mask material 50, and the left and right edges are sewn to manufacture the mask 1. At this time, it is preferable to weave the end portion inward and sew so that the cutting edge where the fiber is exposed does not appear.
Although an example of a mask manufacturing method has been introduced here, the mask manufacturing method is not limited to the above manufacturing method in the present invention.

The mask of the present invention is not limited to the above embodiment. In the above embodiment, the mask having a three-layer structure is mentioned, but another functional layer or the like may be inserted between the outer layer and the inner layer to form a multi-layer structure having four or more layers.
The inner stitch 30 of the present invention may express words and characters from a plurality of stitches as long as it connects the intermediate layer and the inner layer. As the inner stitch, for example, the inner stitch may be the character "King" as shown in FIG. 4b, or the message "Thank you" may be used as shown in FIG. 4c. When using words or letters in this way, the message can be sent only to the user. Further, when box pleats are applied as in the mask 10, the back surface 13c of the pleats is covered with the upper folding portion 13a and the lower folding portion 13b before use, as shown in FIG. 2b, until immediately before use. The message is hidden and cannot be seen. It is the best gift to produce such a small surprise.
