In addition, since it intervenes between the mask and the face when worn, damage to the mask can be reduced and the hygienic state of the mask can be maintained. For example, in the case of a disposable mask, it may be discarded even though the mask is worn for a short time, which is not preferable in terms of environmental hygiene. However, if this mask sheet is used, the hygiene state of the mask can be maintained. Therefore, even a disposable mask can be used multiple times.

Further, by sandwiching this mask sheet between the mask and the face, various effects can be expected. For example, for women, it is possible to prevent cosmetics from adhering to the mask, and it is possible to prevent the material of the mask from coming into direct contact with the skin, so that a skin care effect can be expected. Further, since the mask sheet is formed of threads and absorbs moisture, the effect of preventing fogging of the eyeglasses can be expected.

In the mask sheet according to the embodiment of the present invention, the knitting structure may include a base yarn and a functional yarn woven into the base yarn.
According to this configuration, since the knitting structure of the mask sheet contains the functional yarn, the function of the functional yarn can be imparted to the mask sheet.

The base yarn may mean a natural fiber or a synthetic fiber. On the other hand, the functional yarn may mean a yarn to which functions such as antibacterial property, deodorant property, bactericidal property, moisturizing property, and conductivity are imparted by processing natural fiber or synthetic fiber, for example. .. The processing method may be, for example, a processing method of coating a substance having an antibacterial function (for example, silver) on a natural fiber or a synthetic fiber by a method such as vapor deposition, or for example, a natural fiber or a synthetic fiber having a moisturizing function. A processing method may be used in which a substance having the above (for example, collagen, hyaluronic acid, etc.) is blended.

In the mask sheet according to the embodiment of the present invention, the functional thread may contain a silver thread.
According to this configuration, the antibacterial and deodorant properties of silver contained in the silver thread can be exhibited.
In the mask sheet according to the embodiment of the present invention, the base yarn may contain silk yarn.

The mask sheet according to the embodiment of the present invention has a first surface in contact with the inner surface of the mask and a second surface opposite to the first surface, and the first surface of the mask sheet is It may be formed with an uneven structure.
According to this configuration, the uneven structure can improve the frictional force between the inner surface of the mask and the sheet, so that the sheet can be prevented from being displaced with respect to the mask. That is, the uneven structure exerts the anti-slip effect of the sheet.

In the mask sheet according to the embodiment of the present invention, the second surface of the mask sheet may be formed of a plain structure knitted by a flat knit.
According to this configuration, by making the surface that touches the face (second surface) a plain structure, it is possible to reduce the feeling of ruggedness when the sheet touches the skin.
The mask sheet according to the embodiment of the present invention is a mask sheet arranged between a human face and a sanitary mask, and is a first knitting structure including a silk thread and a silver thread woven into the silk thread. Includes a first area that covers the mouth and nose of the wearer of the mask.

According to this configuration, since the mask sheet is knitted with a knitted structure, it can be used repeatedly by washing with a washing machine, for example. In addition, since it intervenes between the mask and the face when worn, damage to the mask can be reduced and the hygienic state of the mask can be maintained. For example, in the case of a disposable mask, it may be discarded even though the mask is worn for a short time, which is not preferable in terms of environmental hygiene. However, if this mask sheet is used, the hygiene state of the mask can be maintained. Therefore, even a disposable mask can be used multiple times.

Further, by sandwiching this mask sheet between the mask and the face, various effects can be expected. For example, for women, it is possible to prevent cosmetics from adhering to the mask, and it is possible to prevent the material of the mask from coming into direct contact with the skin, so that a skin care effect can be expected. Further, since the mask sheet is formed of threads and absorbs moisture, the effect of preventing fogging of the eyeglasses can be expected.
Furthermore, by knitting a silver thread into the first region covering the mouth and nose, the antibacterial and deodorant properties of silver can be exhibited. Further, a silk thread having excellent hygroscopicity and moisturizing property is included in the first region. This is preferable as a measure against dry throat and mouth, and it is also possible to experience the smooth and smooth feel of silk.

The mask sheet according to the embodiment of the present invention may include a second region formed on both sides in the lateral direction with respect to the first region and knitted with a second knitting structure containing silk yarn.
Since the second area of the sheet does not particularly cover the mouth and nose of a person, by knitting with silk thread, for example, the cheeks and chin can experience the original high-quality feel of silk.
The mask sheet according to the embodiment of the present invention has a first surface in contact with the inner surface of the mask and a second surface opposite to the first surface, and the first surface of the first region is It may be formed by a concavo-convex structure knitted by tuck knitting.

According to this configuration, the uneven structure can improve the frictional force between the inner surface of the mask and the sheet, so that the sheet can be prevented from being displaced with respect to the mask. That is, the uneven structure exerts the anti-slip effect of the sheet. Further, since the uneven structure is knitted by tack knitting, the uneven structure can be easily formed only by adjusting the knitting program on the knitting machine side for manufacturing the sheet.
The mask sheet according to the embodiment of the present invention may be knitted with a non-sewn knitted structure.
According to this configuration, there is no sewn portion on any surface or side of the mask sheet in contact with the wearer's skin, and damage to the skin can be reduced.

FIG. 1 is a schematic perspective view of a mask sheet 1 according to an embodiment of the present invention. FIG. 2 is a schematic perspective view of the mask sheet 1 according to the embodiment of the present invention. FIG. 3 is a cross-sectional view showing a section III-III of FIG. FIG. 4 is a diagram for explaining the knitting structure of the first region 4 of the mask sheet 1. FIG. 5 is a diagram for explaining the knitting structure of the second region 5 of the mask sheet 1. FIG. 6 is a diagram for explaining how to use the mask sheet 1.

The mask sheet 1 is arranged and used between a human face and a sanitary mask. Since the mask sheet 1 also plays a role of capturing dust and the like adhering to the inner surface of the mask, for example, it may be referred to as a mask filter.
The mask sheet 1 has, for example, a knitting structure knitted using a flat knitting machine having at least a pair of front and rear needle beds facing each other in the front-rear direction (for example, "SWG061N" manufactured by Shima Seiki Seisakusho Co., Ltd.). The knitting structure of the mask sheet 1 is not knitted by splicing a plurality of parts consisting of different knitting structures by sewing or adhesive, but the knitting structures that knit each part of the mask sheet 1 are knitted loops with each other. It is organized by connecting with. In addition, the knitting products manufactured by this type of flat knitting machine are non-sewn. Therefore, there is no sewn portion on any surface or side of the mask sheet 1 in contact with the wearer's skin, and damage to the skin can be reduced.

As shown in FIGS. 1 and 2, the mask sheet 1 has a quadrangular sheet shape, and has a first surface 2 and a second surface 3 on the opposite side thereof. The first surface 2 of the mask sheet 1 is a surface that contacts the inner surface of the mask when worn, and the second surface 3 of the mask sheet 1 is a surface that contacts the skin of a person's face when worn.
In this embodiment, the mask sheet 1 is rectangular, and may have a length L of 12 cm to 16 cm and a width W of 6 cm to 9 cm, for example. The size of the mask sheet 1 is not limited to the above range, and may be different for adults and children, for example. Further, the shape of the mask sheet 1 does not have to be quadrangular, and may be circular, oval, or the like.

The knitting structure of the mask sheet 1 is formed of a base yarn and a functional yarn woven together with the base yarn.
As the base yarn, for example, natural fibers, synthetic fibers and the like can be used. Examples of natural fibers include cotton yarns, silk yarns, wool yarns, cashmere yarns and the like, and examples of synthetic fibers include polyester yarns, rayon yarns, acrylic yarns, nylon yarns and polyurethane yarns. Further, the base yarn may be a blended yarn of a plurality of natural fibers, a blended yarn of a plurality of synthetic fibers, and a blended yarn of a natural fiber and a synthetic fiber. In this embodiment, silk yarn is used as the base yarn. By using silk yarn having excellent hygroscopicity and moisturizing properties, it is preferable as a measure against dry throat and throat, and it is also possible to experience the smooth and smooth feel of silk.

The functional yarn may be, for example, a yarn to which functions such as antibacterial property, deodorant property, bactericidal property, moisturizing property, and conductivity are imparted by processing natural fiber or synthetic fiber. The processing method may be, for example, a processing method of coating a substance having an antibacterial function (for example, silver) on a natural fiber or a synthetic fiber by a method such as vapor deposition, or for example, a natural fiber or a synthetic fiber having a moisturizing function. A processing method may be used in which a substance having the above (for example, collagen, hyaluronic acid, etc.) is blended. In this embodiment, a silver thread is used as the functional thread. As a specific silver thread, for example, "sterling silver thread Mufan (registered trademark)" manufactured by Mufan Co., Ltd. can be used. By using the silver thread, the antibacterial property and deodorant property of the silver contained in the silver thread can be exhibited.

The mask sheet 1 includes a first region 4 and a second region 5. The first region 4 is an region that covers the mouth and nose of the wearer of the mask, and is formed in the central portion of the mask sheet 1 in the length direction. On the other hand, the second region 5 is not an region covering the wearer's mouth and nose, but an region covering, for example, the cheeks and chin around the mouth. The second region 5 is formed on both sides in the lateral direction (longitudinal direction of the mask sheet 1) with respect to the first region 4. In this embodiment, strip-shaped regions having a width of 1.5 cm to 2 cm are formed as a pair of second regions 5 from both ends 6 in the longitudinal direction of the mask sheet 1, and are sandwiched between the pair of second regions 5 in a rectangular shape. The region is formed as the first region 4.
As shown in FIG. 3, the first region 4 of the mask sheet 1 is formed in the form of a single cloth in which a hollow portion is not formed in the thickness direction, and the second region 5 of the mask sheet 1 is formed. , It is formed in a cylindrical shape in which a hollow portion 7 is formed in the thickness direction.

In the first region 4, the first surface 2 is formed by the concave-convex structure 8, and the second surface 3 is formed by the plain structure 9. In the concave-convex structure 8, a plurality of concave portions 10 and convex portions 11 are regularly arranged over the entire first region 4. In FIG. 1, the first region 4 is shown by hatching a special pattern, but this pattern does not show the pattern of the uneven structure 8. On the other hand, the plain structure 9 of the first region 4 does not have any conspicuous unevenness on the surface of the mask sheet 1, and is, for example, a visually and tactilely flat structure. That is, the first region 4 is formed in the shape of a single cloth in which two types of surfaces, an uneven surface and a flat surface, are formed on the front and back surfaces.

Such a first region 4 is formed on one surface (in this embodiment, the first region 4) by knitting a knitting structure so as to cross the needles of the front and rear needle beds by using, for example, the above-mentioned flat knitting machine. The two surfaces 3) can be formed by flat knitting, and the other surface (the first surface 2 in this embodiment) can be formed by tack knitting. Then, by knitting the first surface 2 by tack knitting, the concave-convex structure 8 can be selectively formed on the first surface 2. The number of tacks when knitting the first region 4 (the number of loops held by the knitting needles for knitting one course of tucking) varies depending on the type of knitting needles and the type of yarn, but is, for example, 8 to 10 times. There may be.

On the other hand, the second region 5 is formed of a plane structure 12 over both the first surface 2 and the second surface 3. The second region 5 can be formed into a cylindrical shape by, for example, using the above-mentioned flat knitting machine to knit a knitting structure similar to that of a flat knitting portion such as a general glove or sock. .. In FIG. 2, the second region 5 is shown by hatching a special pattern, but this pattern is attached to distinguish it from the pattern showing the concave-convex structure 8 in FIG. 1, and is attached to the plain structure 12. It does not show a pattern.

Next, as shown in FIG. 4, the first region 4 of the mask sheet 1 is knitted with the first knitting structure 15 including both the silk yarn 13 and the silver yarn 14, and the second region of the mask sheet 1 is formed. 5 is knitted with a second knitting structure 16 made of silk yarn 13, as shown in FIG. In FIG. 4, for the sake of clarity, the silk thread 13 and the silver thread 14 are shown as if they were one thread. Further, in FIGS. 4 and 5, a loop state due to flat knitting is shown as an example of the first knitting structure 15 and the second knitting structure 16.

As described above, in the first region 4 covering the mouth and nose, by knitting the silver thread 14, the antibacterial property and deodorant property of silver can be exhibited, and the silk thread 13 having excellent hygroscopicity and moisturizing property can be used. It is preferable as a measure against dry mouth and throat, and you can also experience the smooth and smooth feel of silk. On the other hand, in the second region 5 covering the cheeks and chin, by omitting the silver thread 14 which is harder than the silk thread 13, the cheeks and chin can experience the original high-quality feel of silk.
Further, the first knitting structure 15 of the first region 4 may be a structure knitted by a knitting method (plating structure) in which the front yarn is the silk yarn 13 and the back yarn is the silver yarn 14. As a result, the silk thread 13 is always exposed on the surface of the human face in contact with the skin, and the amount of the silver thread 14 exposed can be significantly reduced. As a result, it is possible to prevent the silver thread 14, which is harder than the silk thread 13, from coming into contact with the skin, so that the wearing feeling of the mask sheet 1 can be improved. On the other hand, even if the silver thread 14 is used as the back thread, there is no change in the original antibacterial and deodorant effects of the silver thread 14.

The mask sheet 1 can be used, for example, when wearing a disposable mask 17 made of a non-woven fabric, as shown in FIG. The disposable mask 17 has an outer surface 18 that touches the outside air and an inner surface 19 that touches the human face, and the mask sheet 1 is attached to the inner surface 19. For example, the first surface 2 of the mask sheet 1 faces the inner surface 19 of the disposable mask 17, and the mask sheet 1 is attached to the inner surface 19 of the disposable mask 17.

An uneven structure 8 is formed on the first surface 2 of the mask sheet 1, and the mask 17 is caught on the cloth of the mask 17 to generate a relatively large frictional force with the mask 17, so that, for example, a pocket or the like. It can be easily attached without separately providing the attachment portion on the mask 17. Then, by wearing the mask 17 with the mask sheet 1 attached, the mask sheet 1 can be interposed between the mask 17 and the face.

As described above, since the mask sheet 1 is knitted with a knitted structure (for example, the first knitted structure 15 and the second knitted structure 16 shown in FIGS. 4 and 5), it is repeatedly used by washing with, for example, a washing machine. can do. Further, since the mask 17 is interposed between the mask 17 and the face when worn, damage to the mask 17 can be reduced and the hygienic state of the mask 17 can be maintained. For example, in the case of the disposable mask 17 as in this embodiment, the mask 17 may be discarded even though it is worn for a short time, which is not preferable in terms of environmental hygiene. For example, since the hygienic state of the mask 17 can be maintained, even the disposable mask 17 can be used a plurality of times.

Further, by sandwiching the mask sheet 1 between the mask 17 and the face, various effects can be expected. For example, a woman can prevent cosmetics from adhering to the mask 17, and can prevent the material of the mask 17 from coming into direct contact with the skin, so that a skin care effect can be expected. Further, since the mask sheet 1 is formed of threads and absorbs moisture, it can be expected to have an effect of preventing fogging of eyeglasses.

Although the embodiments of the present invention have been described above, the present invention can also be implemented in other embodiments.
For example, in the above-described embodiment, an example of using the mask sheet 1 as a disposable mask 17 (nonwoven fabric mask) has been taken up, but the mask sheet 1 is a mask that can be used repeatedly like a cloth mask. Can also be used for.
Further, in the above-described embodiment, the silver thread 14 is used as the functional thread, but for the purpose of enhancing the moisturizing function of the mask sheet 1, a moisturizer in which hyaluronic acid or the like is blended in place of the silver thread 14 or together with the silver thread 14. Threads may be used.

Further, in the above-described embodiment, the knitting structure of the second region 5 of the mask sheet 1 is knitted by flat knitting. You may organize it.
In addition, various design changes can be made within the scope of the matters described in the claims.
