Mask {Mask}

The present invention relates to a mask, and to a mask in which a natural fiber nonwoven fabric is used to improve the feeling of touch, and a hydrophilic material is used on the inner surface to improve skin texture.

In addition to the recent fine dust generated in Korea, the increase in the combustion of fossil fuels due to the industrialization of China is increasing the number of fine dust introduced into the country, increasing exposure to fine dust. Fine dust contains a large amount of toxic compounds and heavy metals, and when inhaled by humans, it is known to cause diseases such as heart attack, asthma, bronchitis, pneumonia, and lung cancer.

According to one study, there is also a report that about 20,000 premature deaths and lung-related diseases occur annually in the metropolitan area only due to fine dust. A mask is used to block such fine dust from entering the human body.

In adding reference numerals to elements of each drawing in the present specification, it should be noted that, even though they are indicated on different drawings, only the same elements are to have the same number as possible. In addition, in describing the present invention, when it is determined that a detailed description of related known technologies may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a front view of a mask according to a first embodiment of the present invention, FIG. 2 is a side view of a mask according to a first embodiment of the present invention, and FIG. 3 is a cross-sectional view of the mask according to the first embodiment of the present invention. . In addition, Figures 4 and 5 are views showing a fusion unit according to the present invention.

1 to 5, a mask 1 according to a first embodiment of the present invention includes a body portion 10 and a fixing portion 20.

The main body 10 covers the user's respirator. At this time, the main body 10 is provided to be folded based on the left and right centers, and the mask 1 is in a flat state as the main body 10 is folded so that storage may be convenient.

The body portion 10 may include a nose portion 11, a mouth portion 12, and a jaw portion 13. The nose 11 forms an upper side of the main body 10 and covers the user's nose, and may have a shape that increases in height toward the left and right centers.

When the mask 1 is stored in a folded state and both sides are unfolded, the nose 11 is spread at an obtuse angle based on the left and right centers, covering the user's nostrils and left and right portions, and in close contact with the face, thus preventing the inflow of foreign substances, etc. have.

However, in order for the nose 11 to be in close contact with the face around the nose while covering the nose, it may be desirable to have a curved hill shape, not a simple mountain shape, and the nose 11 to maintain this shape ( 11) a steel wire 111 may be provided.

The steel wire 111 may be provided on the upper side of the nose part 11 or adjacent to the upper side, and may be produced by coating a synthetic resin such as polyolefin on the metal core, but specifically limiting the material of the steel wire 111 no.

The steel wire 111 is provided to be symmetrical left and right, and has a characteristic of maintaining the changed shape when the shape is changed by external pressure. Therefore, the user, after spreading the main body 10 and applying the nose 11 to the nose, press the steel wire 111 adjacent to the right and left of the nose to deform, so that the steel wire 111 is deformed to correspond to the shape of the face around the nose. I can. At this time, the nose 11 may be kept in close contact with the face by the deformed steel wire 111.

A course sponge (not shown) may be provided on the inner surface of the nose 11, which may be located inside the steel wire 111. The cospong is made of a synthetic resin such as polyurethane, and may serve as a cushion between the steel wire 111 and the face.

Therefore, in this embodiment, it is possible to block the uncomfortable touch from being imparted to the face by the steel wire 111 made of a hard material such as metal, and allow the body part 10 to sufficiently adhere to the bends formed around the nose blades through the cosponge. have.

The mouth portion 12 is provided under the nose portion 11 and forms both sides of the body portion 10 and covers the user's mouth. The mouth part 12 is provided integrally with the nose part 11 and may not form a boundary line with the nose part 11, but a layer fixing part 121 to be described later is provided at the boundary between the mouth part 12 and the nose part 11 There can be.

The mouth portion 12 is provided to have a relatively larger area than the nose portion 11 to cover the user's mouth and cheeks, and fixing portions 20 may be provided on both sides of the mouth portion 12. Of course, the fixing part 20 may be provided to be fixed over the mouth part 12 and the nose part 11.

A layer fixing part 121 is provided at the mouth part 12. The layer fixing part 121 is a fusion-bonded portion of the layers constituting the body portion 10 in a form of a line, etc. to fix the shape, and may be a portion fused in a line inclined downwards facing both sides from the center. In addition, the layer fixing portion 121 may form a portion that is bent when the body portion 10 is unfolded.

That is, when the body portion 10 is unfolded, the upper and lower portions thereof are unfolded to form an obtuse angle based on the layer fixing portion 121, and in this case, the body portion 10 may be spaced apart to have a sufficient distance from the upper portion of the ball. That is, the layer fixing unit 121 is configured to secure a wide breathing space in front of the respirator when the main body 10 is unfolded.

At this time, the layer fixing part 121 may not be provided at the left and right centers, and may be provided symmetrically with respect to the left and right centers. That is, the layer fixing part 121 is provided in a pair spaced apart from each other with the left and right centers therebetween, and this is to prevent the folding of the layer fixing part 121 from being obstructed when the main body 10 is folded flat. .

In addition, as described above, the layer fixing part 121 may be provided on the mouth part 12, it may be seen as being provided at the boundary line between the mouth part 12 and the nose part 11, and in the drawing, the layer fixing part 121 Although it is shown that each of the left and right sides is provided as a pair, of course, a plurality of the layer fixing units 121 may be provided in the vertical direction.

That is, in this embodiment, the layer fixing unit 121 can be any structure or arrangement if it can secure a wider breathing space between the respirator and the main body 10 when the main body 10 is unfolded and fixed to the respirator. .

In this embodiment, the inner surface of the body portion 10 may be made of a natural fiber nonwoven fabric, and the outer surface of the body portion 10 may be made of a synthetic fiber nonwoven fabric. Although it is impossible to fix the natural fiber nonwoven fabrics by fusion bonding, the layer fixing part 121 fusion bonds the natural fiber nonwoven fabric and the synthetic fiber nonwoven fabric stacked on each other, so that fusion is possible without a problem.

The jaw portion 13 is provided under the mouth portion 12 and forms the lower side of the main body portion 10 and covers the user's jaw. Since the jaw portion 13, the mouth portion 12, and the nose portion 11 may all be provided integrally, the mouth portion 12 and the jaw portion 13 may not be distinguished by a boundary line.

In addition, the layer fixing portion 121 may or may not be provided between the jaw 13 and the mouth 12, and when the layer fixing portion 121 is not provided, the jaw 13 and the mouth 12 may be visually It may be integrated so as not to be distinguished.

The jaw part 13 includes a fusion part 131 that is cut up and down and then joined. The fusion part 131 is formed from the lower side of the jaw part 13 to the upper side with respect to the center of the left and right, and the fusion part 131 forms a triangular shape before being joined, and then forms a line shape while being joined. have.

In this case, when the body portion 10 is unfolded, the jaw portion 13 is opened to form an obtuse angle to the left and right with respect to the fusion portion 131, and the jaw can be stably wrapped. At this time, the length of the fusion part 131 is not particularly limited, and a method in which the fusion part 131 is joined after cutting is also not particularly limited.

However, when the fusion part 131 is joined by fusion or the like, a pair of sides that are cut in the jaw part 13 and face each other protrude toward the outside, and then the inner surfaces may overlap each other to be fused. However, since the body portion 10 is made of a natural fiber non-woven fabric, the fusion portion 131 is a portion where the natural fiber non-woven fabric abuts each other.

In this case, there is a problem that the natural fiber nonwoven fabric cannot be melted, but in this embodiment, the synthetic fiber nonwoven fabric laminated on the natural fiber nonwoven fabric is melted by limiting the fusion size of the fusion unit 131, so that the synthetic fiber nonwoven fabric is melted. It is possible to achieve fusion between natural fiber nonwovens through.

As shown in FIG. 4, the fusion unit 131 may be fused to have a shape in which a plurality of fusion units 131a are arranged in a shape such as a line. The fusion unit 131a may have various shapes, such as a circle, a trapezoid, a pentagon, and an ellipse, as shown in FIG. 5, and the length of the longest side of the fusion unit 131a may be defined as the line width of the fusion unit 131. . However, when the fusion unit 131a is circular or elliptical, the longest diameter may be the line width of the fusion unit 131.

The line width of the fusion part 131 may be 0.5 mm or more, but may be 0.7 mm or more, 0.9 mm or more, or 1.2 mm or more. In addition, the fusing unit (131a) constituting the fusing portion 131, or the like may be equal to or greater than an area of 0.25mm ² 0.40mm ² or more, but, more than 0.54mm ² or more than 1.0mm ^2.

If the area of the fusion unit 131a is less than 0.25mm ² or the line width of the fusion unit 131 is less than 0.5mm, fusion to the part where the natural fiber nonwoven fabric abuts is impossible, and even if possible, the fusion strength is not secured and thus falls easily.

On the other hand, if the area of the fusion unit 131a is 0.25 mm ² or more and the line width of the fusion unit 131 is 0.5 mm or more, even if the natural fiber non-woven fabric is in contact with each other, the synthetic fiber non-woven fabric padded with the natural fiber non-woven fabric partially melts. , Fusion between natural fiber nonwoven fabrics may be possible by the melted synthetic fiber nonwoven fabric.

However, if the area of the fusion unit 131a exceeds 1.5 mm ² or the line width of the fusion unit 131 is 1.5 mm or more, fusion between natural fiber non-woven fabrics using the melting of synthetic fiber non-woven fabrics may be possible. As the size of the damaged portion (the fusion portion 131 and the fusion unit 131a) becomes too large, there is a problem of imparting a foreign body feeling when worn.

Therefore, the present invention allows the area of the fusion unit 131a to be 0.25 mm ² or more and the line width of the fusion unit 131 to be 0.5 mm or more, thereby enabling fusion between natural fiber nonwoven fabrics, while allowing the fusion unit 131a and The size of the fusion part 131 is not too large to ensure a fit.

Through this limitation, in this embodiment, fusion between natural fiber nonwoven fabrics through melting of synthetic fiber nonwoven fabrics can be realized and fusion strength can be secured for a portion where natural fiber nonwoven fabrics are in contact with each other and thus fusion is difficult.

The fusion part 131 formed by fusion may have a line shape protruding outward, and accordingly, in this embodiment, when forming the fusion part 131 on the chin part 13, a foreign body feeling may not be imparted to the face. .

The body portion 10 including the nose portion 11, the mouth portion 12, and the jaw portion 13 may be provided so as to omit the nose portion 11, the jaw portion 13, and the like. However, in the present embodiment, the main body 10 may be assembled after the nose 11, the mouth 12, and the jaw 13 are separately provided, or may be provided integrally.

In addition to the structures mentioned above, the main body 10 may employ any structure as long as it can give a three-dimensional shape, and some other structures will be described through other embodiments of the present specification. For example, the main body portion 10 may have a flat shape in which the folds in the horizontal direction are folded, and may form a three-dimensional shape while the folds are spread up and down. Alternatively, the main body 10 may itself maintain a three-dimensional shape.

The body portion 10, which may have various structures, may have a structure in which a natural fiber nonwoven fabric and a synthetic fiber nonwoven fabric are stacked, and at least an inner surface in contact with the user's skin may include a natural fiber nonwoven fabric. At this time, it should be noted that the present invention is not limitedly interpreted as being made of only natural fiber nonwoven fabrics. For example, the inner surface may encompass a natural fiber nonwoven fabric and a synthetic fiber nonwoven fabric blended.

Nonwoven fabric is a cotton member that physically or chemically fixes the fibers after they are arranged to overlap in a certain direction or in a negative direction, unlike a fabric that undergoes a weaving process by dividing fibers into warp and weft yarns and crossing each other. That is, a nonwoven fabric is a fabric-type material in which a fiber aggregate is bonded by chemical or mechanical methods such as adhesion, fusion bonding, and enveloping without going through spinning, weaving, or braiding, which are the process of changing fibers into yarn and weaving yarns together.

Depending on whether the fibers constituting the nonwoven fabric are synthetic fibers or natural fibers, nonwoven fabrics can be divided into natural fiber nonwoven fabrics and synthetic fiber nonwoven fabrics. However, the natural fiber nonwoven fabric made of natural fibers is not melted and thus cannot be used for fusion, and has not been generally used as a material for a conventional mask.

Or, in the case of using a natural fiber nonwoven fabric as a material for a conventional mask, a method of fixing by using sewing was used in consideration of the fact that fusion was impossible.In this case, since the nonwoven fabric was not subjected to a woven fabric process, the fixing force when fixing by sewing There was a problem that it could not be sufficiently secured, and there was a problem that the manufacturing cost increased as the sewing process was used.

However, in this embodiment, by applying a natural fiber nonwoven fabric made of natural fibers to the inner surface of the body portion 10, the feeling of contacting the skin when the user wears the mask 1 can be improved in a comfortable and soft direction. , Synthetic fiber non-woven fabric is applied to a portion other than the inner surface of the main body 10, so that both the fusion bonding between the inner surfaces of the main body 10 or the inner surface of the main body 10 and other parts may be possible.

The outer surface of the body part 10 opposite to the user's skin may be made of a synthetic fiber nonwoven fabric, and the body part 10 may maintain a structure in which a natural fiber nonwoven fabric and a synthetic fiber nonwoven fabric are stacked when worn by the user, at least A natural fiber nonwoven fabric and a synthetic fiber nonwoven fabric may be stacked around the main body 10 and fixed to each other by a layer fixing part 14.

That is, the main body 10 may have an inner surface made of a natural fiber nonwoven fabric and an outer surface made of a synthetic fiber nonwoven fabric are fixed to each other by the layer fixing part 14. Accordingly, at least a portion of the circumference of the main body 10 may have a layer fixing part 14 in which layers are fused to each other, and the layer fixing part 14 may have a reduced thickness and increased strength compared to other parts.

The layer fixing part 14 is a fusion bonding of the natural fiber non-woven fabric and the synthetic fiber non-woven fabric stacked in contact with each other, and such fusion bonding is the same/similar to the layer fixing part 121 described above, but the natural fiber non-woven fabrics are fused together. It may be different from the fusion part 131.

Since the fusion part 131 is a part where the natural fiber nonwoven fabrics abut each other, the fusion size and the like should be limited as described above in order to fuse the natural fiber nonwoven fabric by melting the synthetic fiber nonwoven fabric in contact with the natural fiber nonwoven fabric, but the layer fixing part 14 In the case of, 121), since the natural fiber nonwoven fabric and the synthetic fiber nonwoven fabric are fused together, the fusion size of the layer fixing portions 14 and 121 may be different from the fusion size of the fusion unit 131. For example, the fusion size (line width or fusion area of the fusion units 14a and 121a) of the layer fixing portions 14 and 121 may be smaller than the fusion size of the fusion unit 131.

The body portion 10 may have a structure in which the entire inner surface contacting the user's skin is made of a natural fiber nonwoven fabric, and the basis weight of the synthetic fiber nonwoven fabric is relatively large compared to the basis weight of the natural fiber nonwoven fabric. This is to enable the fusion bonding of the fusion portion 131 rather than the fusion bonding of the layer fixing portions 14 and 121.

As an example, the basis weight of the synthetic fiber nonwoven fabric may occupy 50 parts by weight or more (for example, 50 to 83 parts by weight) of the total basis weight of the body part 10, for which the layer constituting the body part 10 is described. This will be explained in detail in the following section.

The body portion 10 may be formed by stacking at least three or more layers. For example, the body portion 10 includes an outer surface 101, a rigid portion 102, a filter 103, and an inner surface 104. It may be made, and the rigid part 102 may be omitted here.

The outer surface 101 is exposed to the outside and may be made of a synthetic fiber nonwoven fabric such as a spunbond nonwoven fabric made of polypropylene, and the outer surface 101 may be provided to have a basis weight of 10gsm to 80gsm, but the material and basis weight of the outer surface 101 Is not limited as above. The outer surface 101 may first filter out foreign substances.

The outer surface 101 may be formed of a plurality of layers, in which case the outer surface 101 provided inside is as described above, and the outer surface 101 provided on the outermost side is a synthetic fiber such as a spunbond nonwoven fabric made of polypropylene. It is made of a nonwoven fabric and may be provided to have a basis weight of 10 gsm to 70 gsm, but the material and basis weight of the outer surface 101 are not particularly limited. However, in this embodiment, the outer surface 101 may be made of a synthetic fiber nonwoven fabric of which the type is not limited.

The rigid part 102 allows the body part 10 to maintain a three-dimensional shape so as to sufficiently secure a breathing space between the respirator and the body part 10 when the body part 10 is unfolded.

The rigid portion 102 is provided between the outer surface 101 and the filter 103, but the stacking order is not particularly limited. That is, the rigid part 102 may be provided between the outer surface 101 and the filter 103 and/or between the inner surface 104 and the filter 103.

When the rigid portion 102 is provided in a size corresponding to the outer surface 101 or the like, or has a size slightly smaller than the outer surface 101 and is stacked only on a part of the outer surface 101, the mask 1 is folded by the rigid portion 102 The three-dimensionality can be further improved. For example, the rigid portion 102 may have a size that covers the respiratory tract, but is spaced apart from the upper side of the nose 11 or the left and right sides of the mouth 12 and/or the lower side of the jaw 13.

The rigid part 102 may be disposed to overlap at least a portion of the layer fixing part 121, and the mask 1 together with the layer fixing part 121 may be formed into a three-dimensional shape to secure a breathing space.

The rigid part 102 may be made of a material of a synthetic fiber nonwoven fabric such as a spunbond nonwoven fabric, and may have a basis weight of 30gsm to 70gsm, but is not limited thereto. For example, the rigid portion 102 may be folded or bent, but may have a higher density or higher strength than the body portion 10.

For example, the rigid part 102 may have a relatively thick fiber thickness and/or a thicker thickness than the outer surface 101, the filter 103, and the inner surface 104. In this case, when the body portion 10 is unfolded, the circumference of the rigid portion 102 may affect the three-dimensional shape of the body portion 10.

The filter 103 is provided on the inner side of the outer surface 101 and may be made of a synthetic fiber nonwoven fabric such as a meltblown nonwoven fabric, and may have a basis weight of 10gsm to 60gsm, but as mentioned above, the material and the basis weight It is not limited as above. The filter 103 may filter out foreign matter flowing through the double outer surface 101.

Contaminants such as fine dust and yellow dust may be filtered out through the outer surface 101 and the filter 103 and blocked from entering the respiratory tract.

The inner surface 104 is provided inside the filter 103 and faces the respirator. Unlike the outer surface 101 and the filter 103, the inner surface 104 may be made of a natural fiber nonwoven fabric made of natural fibers such as pure cotton. At this time, the basis weight of the inner surface 104 may be 20gsm to 80gsm, but is not particularly limited.

The inner surface 104 is a portion that forms an inner surface of the body portion 10 in contact with the user's skin, and may be made of a natural fiber nonwoven fabric in which natural fibers such as pure cotton are physically and/or chemically bound as described above. At this time, the natural fiber may be a natural fiber nonwoven fabric such as pure cotton of vegetable fiber, hemp, wool of animal fiber, silk, rayon, Tencel, Modal, etc., but is not particularly limited.

On the other hand, the filter 103 and the outer surface 101 stacked on the outside compared to the inner surface 104 may be made of synthetic fiber nonwoven fabric. At this time, the outer surface 101, the filter 103, and the inner surface 104 constituting the main body 10 are stacked with each other and the layer fixing part 14 and/or the layer fixing part 14 provided around the main body 10 and/or The layer fixing part 121 may be fixed by fusion bonding.

While natural fiber nonwoven fabrics such as pure cotton do not melt, synthetic fiber nonwoven fabrics made of synthetic fibers such as PP, PE, PET, etc. are melted when ultrasonically fused to form strong bonding strength.

In the case of the layer fixing portions 14 and 121 as described above, the natural fiber nonwoven fabric and the synthetic fiber nonwoven fabric are fused to each other, so even if the fusion size is not specifically limited, the synthetic fiber nonwoven fabric is melted, The structure in which the synthetic fiber nonwoven fabric is laminated (for example, when the body portion 10 is deformed to be worn by a user) can be stably maintained.

In contrast, in the body part 10 where the natural fiber nonwoven fabric contacts each other, such as the fusion part 131, in spite of the problem that the natural fiber nonwoven fabric does not melt, at least some of the components other than the inner surface 104 are made of synthetic fiber nonwoven fabric. By configuring, as the synthetic fiber nonwoven fabric is melted during the fusing process, fusion between the natural fiber nonwoven fabrics can be realized. That is, in this embodiment, in order to solve the problem that fusion between natural fiber nonwoven fabrics is impossible, melting of synthetic fiber nonwoven fabrics may be used.

That is, the body part 10 applies the layer fixing parts 14 and 121 to the part in which the natural fiber nonwoven fabric and the synthetic fiber nonwoven fabric are laminated to each other so that the body part 10 can firmly maintain the laminated structure when worn by the user. And, by applying a fusion portion 131 having a fusion size of a certain or more to the portion where the natural fiber nonwoven fabrics abut each other, the problem in which fusion between the natural fiber nonwoven fabrics is impossible can be solved.

In this embodiment, the body portion 10 may have a basis weight of the synthetic fiber nonwoven fabric of the total basis weight relatively higher than that of the natural fiber nonwoven fabric. For example, if the basis weight of the inner surface 104 is 40gsm, the basis weight of the filter 103 is 30gsm, and the basis weight of the outer surface 101 is 20gsm, the basis weight of the natural fiber nonwoven fabric forming the inner surface 104 is the total basis weight of the main body 10 It occupies 44 parts by weight, on the contrary, the basis weight of the synthetic fiber nonwoven fabric forming the outer surface 101 and the filter 103 may occupy 56 parts by weight of the total basis weight of the body portion 10.

That is, the basis weight of the natural fiber nonwoven fabric in the body portion 10 may occupy 50 parts by weight or more (for example, 50 to 83 parts by weight) of the total basis weight of the body portion 10. This may be the same even when the outer surface 101 is plural or a rigid portion 102 made of a synthetic fiber nonwoven fabric is added.

Therefore, in this embodiment, the basis weight ratio of the natural fiber nonwoven fabric is relatively the same or less than the basis weight ratio of the synthetic fiber nonwoven fabric with respect to the layer constituting the body part 10, thereby ensuring the fusion strength through melting of the synthetic fiber nonwoven fabric during fusion. can do.

The strength (for example, fixed strength) of the main body 10 is shown in the table below. The fixed strength was tested by using a device for an area of 2mm*25mm among the fused parts, fixing it in a natural state without wrinkles on both clamps, and pulling it at a speed of 20cm/min.

Synthetic fiber nonwoven content (%) 47 50 53 62 65 68 Fixed strength (N) Unfused 7.3 10.5 14.4 19.6 21.4

As can be seen from the above table, the content of the synthetic fiber nonwoven fabric must be at least 50 parts by weight to be fused, and the fixing strength, of course, increases as the content of the synthetic fiber nonwoven fabric increases.

However, in the'Guideline for Standard Standards for Health Masks' by the Ministry of Food and Drug Safety, the standard for the tensile strength of the joint of the head strap is defined as 10N. If this standard is applied mutatis mutandis, if the tensile strength standard of the joint is 10N or higher, it is judged that it is fused. Therefore, in this embodiment, the content of the synthetic fiber non-woven fabric is made to be 53 parts by weight or more in the body portion 10, and the fixed strength is 10 N or more, and a natural fiber non-woven fabric is applied to the inner surface of the body portion 10 to make the body part 10 feel comfortable. You can increase it.

That is, the fixing part 20 may implement a closed loop based on the connection part 21.

Here, the connection part 21 may be a part that is fused to the inner surface 104 made of a natural fiber nonwoven fabric, but the body part 10 is made to have a higher basis weight ratio of the synthetic fiber nonwoven fabric than the natural fiber nonwoven fabric, and the connection part 21 There is no problem even if fusion is used as a fixing method.

At this time, the fixing part 20 may be caught in the middle part of the string by the hook parts 22 provided on both sides of the mouth part 12. At least one hook portion 22 is provided on each of both sides of the mouth portion 12, and can be fixed by hanging a string.

In this case, the fixing part 20 may constitute a closed loop extending outward from the upper and lower ends of both sides of the mouth part 12. However, the string is fixed to be immovable in the fixing portion 20, and may be hung to be movable in the hook portion 22.

The user can pull the fixing part 20 and hang it on the ear and place the body part 10 adjacent to the respirator. Conversely, the body part 10 can be separated from the respirator by releasing the jamming of the fixing part 20 from the ear. I can.

11 is a cross-sectional view of a mask according to a sixth embodiment of the present invention.

Referring to FIG. 11, the mask 1 according to the sixth embodiment of the present invention may be formed by stacking at least three or more layers. For example, the main body 10 includes an outer surface 101 and a filter 103. ), hydrophobic portion 105. The inner surface 104 may be laminated.

That is, the present embodiment includes the hydrophobic portion 105 when compared to the first embodiment, and is omitted in the drawings, but it goes without saying that the rigid portion 102 of the first embodiment may be added to the present embodiment. Hereinafter, the present exemplary embodiment is mainly described in terms of differences compared to the first exemplary embodiment, and portions omitted from the description will be replaced with the previous content.

In this embodiment, the filter 103 may be a filter 103 that has been electrostatically treated as a component that prevents the inflow of foreign substances. Here, the filter 103 may be provided to be spaced apart from the inner surface 104 because the electrostatic capacity of the electrostatically treated filter 103 is lost and thus filtering efficiency may be lowered.

Although it will be described later, the inner surface 104 includes a natural fiber non-woven fabric so that moisture is well absorbed, and when the moisture absorbed by the inner surface 104 is transferred to the filter 103, there is a concern that the electrostatic force of the filter 103 may be lowered.

However, in this embodiment, as the filter 103 is spaced apart from the inner surface 104 by the hydrophobic portion 105 located between the filter 103 and the inner surface 104, moisture is transferred from the inner surface 104. Can be blocked.

The inner surface 104 is a portion that can directly contact the user's face and is provided to be spaced apart from the filter 103. As described above, the inner surface 104 may be made of a natural fiber nonwoven fabric or may be formed by blending natural fibers and synthetic fibers to improve texture.

For example, the inner surface 104 may be a spunlace nonwoven fabric manufactured through a method of manufacturing a spunlace, and the spunlace nonwoven fabric is a kind of nonwoven fabric made of a similar structure to a knitted product by tangling the fibers with a flow of high pressure water. it means.

That is, the inner surface 104 may be formed by tangling the synthetic fibers on the natural fibers through a method in which a spunlace is manufactured for blending natural fibers and synthetic fibers.

Here, the natural fiber may be made of at least one of pure cotton, rayon, tencel, and modal, or a combination thereof, the same as/similar to the first embodiment, and the synthetic fiber may be made of island groups such as polypropylene, polyethylene, polyester, etc. have. The types of natural fibers and synthetic fibers as described above may be applied to fibers manufactured by known general techniques, and are not limited thereto.

When the inner surface 104 includes synthetic fibers, the natural fibers of the inner surface 104 may be included, for example, 40% or more of the total weight of the inner surface 104 so that the user can recognize the texture of the natural fibers.

Through this, the inner surface 104 provides the user with the texture of natural fibers, but unlike 100% natural fibers that burn out when heat is applied at a certain temperature or higher, melting may occur on the inner surface 104 due to synthetic fibers. Because of the same/similar to the above-described fusion bonding, when bonding between the inner surface 104 and other parts or bonding between the inner surface 104 is possible, productivity may be improved compared to the sewing method.

However, when the inner surface 104 includes natural fibers, the ability to absorb moisture is higher than that of synthetic fibers, so that the body portion 10 first absorbs moisture. At this time, when the water absorption amount of the inner surface 104 increases by a certain amount or more, moisture may be transferred from the inner surface 104 to the filter 103.

Accordingly, in this embodiment, the hydrophobic portion 105 may be provided to separate the inner surface 104 from the filter 103 so that the filter 103 can be maintained in an electrostatically treated state.

The hydrophobic portion 105 is provided in contact with the filter 103 to prevent moisture from being transferred to the filter 103. In this case, the inner surface 104 is provided to be spaced apart from the filter 103 by the hydrophobic portion 105.

The hydrophobic part 105 may be made of a material having a property of having a low affinity with moisture. For example, the hydrophobic part 105 may be a synthetic fiber nonwoven fabric. Of course, the material of the hydrophobic part 105 is not limited to the above, and any material having hydrophobicity may be used without limitation.

The hydrophobic portion 105 may block moisture from the surrounding environment from being transmitted to the filter 103 through the inner surface 104 when storing the mask 1 or when using the mask 1. Accordingly, the hydrophobic portion 105 can prevent a decrease in electrostatic force of the filter 103.

As described above, the present embodiment has an electrostatically treated filter 103 and an inner surface 104 made of a hydrophilic material to improve texture, and a hydrophobic portion 105 is provided between the filter 103 and the inner surface 104. Moisture absorbed by the inner surface 104 can be prevented from being transferred to the filter 103, thereby preventing the electrostatic force of the filter 103 from being lowered, thereby reducing the deterioration of the purifying function of the mask 1.

The present invention is not limited to the above-described embodiments, and may cover all of a new embodiment created by combining at least one embodiment and a known technology, or a new embodiment created by combining two or more embodiments. Yes, of course.

Although the present invention has been described in detail through specific examples, this is for explaining the present invention in detail, and the present invention is not limited thereto, and within the technical scope of the present invention, those of ordinary skill in the art It would be clear that the transformation or improvement is possible.
