Description

口罩Face mask

本發明有關一種口罩。The invention relates to a mask.

傳統上，作為覆蓋口鼻的口罩的材料，除了不織布以外，還使用紗布等機織布、針織布等織物。由於不織布的密度高，因此具有更好的過濾功能，但較軟的織物具有更好的皮膚觸感（例如，參照專利文獻1）。現有技術文獻專利文獻 Traditionally, as materials for masks covering the mouth and nose, fabrics such as woven fabrics such as gauze and knitted fabrics have been used in addition to non-woven fabrics. Since the nonwoven fabric has a high density, it has a better filtering function, but a softer fabric has a better skin touch (for example, refer to Patent Document 1). prior art literature patent documents

發明所欲解決的問題The problem to be solved by the invention

在使用織物的口罩中，有將多個織物疊置起來並將它們的端部縫合在一起的口罩。通常，織物的邊緣向內折疊並縫合在一起以防止解開。Among masks using fabrics, there are masks in which a plurality of fabrics are stacked and their ends are sewn together. Usually, the edges of the fabric are folded inward and stitched together to prevent unraveling.

因此，這意味著在口罩的邊緣，織物的層數增加，厚度增加。如果邊緣太厚，口罩可能不適合鼻子的形狀或臉部的表面，佩戴者可能會感到不舒服。So this means that at the edge of the mask, there are more layers of fabric and more thickness. If the edges are too thick, the mask may not fit the shape of the nose or the surface of the face, and the wearer may feel uncomfortable.

本發明的目的在於提供一種貼合性良好的口罩。解決問題的技術手段 The object of the present invention is to provide a mask with good fit. technical means to solve problems

本發明的一個態樣是一種口罩(10)，其中將表面織物(11)和裏面織物(12)縫合在一起。表面織物(11)和裏面織物(12)的形狀是，其上端部(1a)的左右是連續的、上端部(1a)的下方是左右分離的。發明功效 One aspect of the invention is a mask (10) in which the face fabric (11) and the inner fabric (12) are sewn together. The shape of the surface fabric (11) and the inner fabric (12) is that the left and right sides of the upper end (1a) are continuous, and the left and right sides of the upper end (1a) are separated.

The front is the Y1 direction in the drawing, and the back is the Y2 direction in the drawing. (Face mask)

圖1是本實施例的口罩10的立體圖。本實施例的口罩10包括本體部1和耳掛部2。本體部1覆蓋了佩戴者的臉部和嘴部。耳掛部2掛在佩戴者的耳朵上，本體部1固定在佩戴者的臉上。Fig. 1 is a perspective view of a mask 10 of the present embodiment. The mask 10 of this embodiment includes a main body 1 and an earhook 2 . The body part 1 covers the wearer's face and mouth. The ear hook part 2 is hung on the wearer's ear, and the main body part 1 is fixed on the face of the wearer.

口罩10還包括伸縮帶14。伸縮帶14可以設置在本體部1的上端部1a上。伸縮帶14的一個例子是使用熱塑性聚氨酯，如Mobilon帶（註冊商標）等製成的樹脂帶。（本體部） The mask 10 also includes stretch straps 14 . The stretch strap 14 may be provided on the upper end portion 1 a of the body portion 1 . An example of the stretch belt 14 is a resin belt made of thermoplastic polyurethane such as Mobilon belt (registered trademark) or the like. (main body)

本體部1具有一個三維形狀，其中口罩10的前中心M凸出。The main body portion 1 has a three-dimensional shape in which the front center M of the mask 10 is convex.

圖2顯示本體部1的分層結構。本體部1具有多層結構。本體部1從正面到背面依次設置有表面織物11、過濾器13和裏面織物12。裏面織物12與佩戴者的臉部接觸。FIG. 2 shows the layered structure of the body portion 1 . The main body portion 1 has a multilayer structure. The main body part 1 is provided with a surface fabric 11, a filter 13 and an inner fabric 12 sequentially from the front to the back. The inner fabric 12 is in contact with the wearer's face.

表面織物11是配置在最前面的針織物。裏面織物12是配置在最後面的針織物。針織物的柔軟性和光滑性高於不織布，這使得佩戴時更加舒適。The surface fabric 11 is the knitted fabric arranged at the front. The inner fabric 12 is the knitted fabric arranged at the rearmost. The softness and smoothness of knitted fabric are higher than that of non-woven fabric, which makes it more comfortable to wear.

針織物的材質沒有特別限定，可以一種或兩種以上組合使用。可以使用的材料的例子包括諸如尼龍6和尼龍66的聚酰胺、諸如聚乙二醇酯的聚酯、諸如聚乙烯的聚酯、以及諸如聚烯烴的聚烯烴或諸如聚酯的合成纖維。The material of the knitted fabric is not particularly limited, and may be used alone or in combination of two or more. Examples of materials that can be used include polyamide such as nylon 6 and nylon 66, polyester such as polyethylene glycol ester, polyester such as polyethylene, and polyolefin such as polyolefin or synthetic fiber such as polyester.

另外，作為針織物的材料，也可以使用具有柔軟觸感的纖維素纖維等。纖維素纖維的例子包括被稱為Cupro的銅氨纖維（例如，由旭化成株式會社生產的Bemberg（註冊商標）等）、黏膠人造纖維、聚纖維素人造絲或精製纖維素纖維等。In addition, as the material of the knitted fabric, cellulose fibers having a soft touch, etc. can also be used. Examples of cellulose fibers include cupro fiber called Cupro (for example, Bemberg (registered trademark) manufactured by Asahi Kasei Co., Ltd., etc.), viscose rayon, polycellulose rayon, refined cellulose fiber, and the like.

針織物的織組例子包括羅紋織物、聯鎖織物、天竺棉、熊天竺棉、斑駁布料、麻袋布料、蓬特織物、米拉諾里布和綵帶等編織。從佩戴方便的觀點來看，優選具有高伸縮度和高彈性的緯編針織物。從提高口罩10的貼合性的觀點來看，優選是熊天竺棉。Examples of weaves for knitted fabrics include weaves such as rib, interlock, geranium, bear geranium, mottled, sack, punt, Milano, and ribbon. From the viewpoint of wearing convenience, weft-knitted fabrics having high stretchability and high elasticity are preferable. From the viewpoint of improving the fit of the mask 10, kuma kuma cotton is preferable.

表面織物11和裏面織物12最好是由具有良好透氣性的針織織物製成，這可以防止呼出的空氣留在口罩10內，減少佩戴時的不適感。透氣性可以通過使用的纖維、纖維的細度或針織結構來提高。The surface fabric 11 and the inner fabric 12 are preferably made of knitted fabrics with good air permeability, which can prevent exhaled air from staying in the mouth mask 10 and reduce discomfort when worn. Breathability can be improved by the fibers used, the fineness of the fibers or the knit structure.

例如，纖維素纖維比例減少的針織品，如銅氨纖維，以及合成纖維比例增加的針織品，如聚酯纖維，具有良好的透氣性，可以優選作為表面織物11和裏面織物12的針織物。For example, knitted fabrics with a reduced proportion of cellulose fibers, such as cupro, and knitted fabrics with an increased proportion of synthetic fibers, such as polyester fibers, have good air permeability and can be preferably used as knitted fabrics for the surface fabric 11 and the inner fabric 12 .

具有優異透氣性的針織物的實例包括蜂巢網、雙面和斑駁布料。Examples of knitted fabrics with excellent air permeability include honeycomb mesh, double face and mottled fabrics.

與佩戴者的臉部接觸的裏面織物12可以具有涼爽的觸感。通過使用上述的聚酰胺、聚烯烴、聚氨酯等合成纖維，能夠提高涼爽的觸感。The inner fabric 12, which is in contact with the wearer's face, may have a cooling feel. By using synthetic fibers such as polyamide, polyolefin, and polyurethane mentioned above, a cool touch can be improved.

作為具有涼爽觸感和良好觸感的針織物，例如，可以使用日本專利第61662995號中公開的針織物。這是一種使用20%以上質量的單紗細度為0.8~4dtex的纖維素纖維的針織物，針織物的填充密度為0.26~0.5g/m ³。這種針織物還具有良好的吸濕和除臭功能。 As the knitted fabric having cool touch and good touch, for example, the knitted fabric disclosed in Japanese Patent No. 61662995 can be used. This is a knitted fabric using more than 20% of the mass of cellulose fibers with a single yarn fineness of 0.8~4dtex, and the packing density of the knitted fabric is 0.26~0.5g/m ³ . This knitted fabric also has good moisture absorption and deodorization functions.

日本專利第6371593號中公開的針織物也適合使用。該針織物是由纖維素纖維與合成纖維混合而成的複合紗與合成纖維的紗交織而成的熊天竺針織物，該針織物中的纖維素纖維的比例為20％以上。Knitted fabrics disclosed in Japanese Patent No. 6371593 are also suitable for use. The knitted fabric is a Xiong Tianzhu knitted fabric formed by interweaving composite yarn formed by mixing cellulose fiber and synthetic fiber and yarn of synthetic fiber, and the proportion of cellulose fiber in the knitted fabric is more than 20%.

過濾器13具有比表面織物11或裏面織物12更高的密度，這可以提高對花粉等異物的屏蔽率。The filter 13 has a higher density than the surface fabric 11 or the inner fabric 12, which can improve the shielding rate of foreign matter such as pollen.

儘管本實施例的過濾器13具有單層結構，但是過濾器13可以具有多層結構。多個過濾器13也可以以越靠近佩戴者過濾效率越高的方式配置。Although the filter 13 of the present embodiment has a single-layer structure, the filter 13 may have a multi-layer structure. The plurality of filters 13 may be arranged so that the closer to the wearer, the higher the filtering efficiency.

從衛生的觀點來看，過濾器13優選具有高的細菌過濾效率(Bacterial Filtration Efficiency; BFE)。BFE根據ASTMF 2101標準量測。From a hygienic viewpoint, the filter 13 preferably has a high bacterial filtration efficiency (Bacterial Filtration Efficiency; BFE). BFE is measured according to the ASTM F 2101 standard.

從抑制花粉擴散的觀點來看，優選過濾器13的花粉過濾效率高。從抑制液滴擴散的觀點來看，優選粒子過濾效率(Particle Filtration Efficiency; PFE)高。PFE根據ASTMF 2299標準量測。From the viewpoint of suppressing the spread of pollen, it is preferable that the pollen filtering efficiency of the filter 13 is high. From the viewpoint of suppressing the spread of droplets, it is preferable that the particle filtration efficiency (Particle Filtration Efficiency; PFE) is high. PFE is measured according to the ASTM F 2299 standard.

過濾器13的示例包括使用由以奈米(nm)為單位的超細纖維製成的奈米纖維的不織布，例如聚四氟乙烯（PTFE）的奈米纖維，以及合成纖維的不織布，如聚乙烯樹脂和聚丙烯樹脂。（耳掛部） Examples of the filter 13 include a nonwoven fabric using nanofibers made of ultrafine fibers in units of nanometers (nm), such as nanofibers of polytetrafluoroethylene (PTFE), and a nonwoven fabric of synthetic fibers such as polytetrafluoroethylene (PTFE). Vinyl and polypropylene resins. (Earhook)

耳掛部2是設置在本體部1左右兩端的環形帶狀構件。例如，帶狀構件是具有伸縮性的伸縮帶等。帶狀構件的一端連接在本體部1的左右端的上側，另一端連接在下側以形成環形。（口罩製造方法） The ear hook portion 2 is an endless belt-shaped member provided at both left and right ends of the main body portion 1 . For example, the belt-shaped member is a stretchable belt or the like. One end of the belt member is connected to the upper side of the left and right ends of the body part 1, and the other end is connected to the lower side to form a ring shape. (Mask manufacturing method)

口罩10可以通過形成本體部1並在本體部1上設置耳掛部2來形成。The mask 10 can be formed by forming a body part 1 and providing an ear hook part 2 on the body part 1 .

本體部1通過將表面織物11、過濾器13和裏面織物12層壓和縫合而形成。縫製前的表面織物11、裏面織物12和過濾器13在前中心M處具有對稱的形狀。The body portion 1 is formed by laminating and sewing a surface fabric 11, a filter 13, and an inner fabric 12. The surface fabric 11, the inner fabric 12 and the filter 13 before sewing have symmetrical shapes at the front center M.

圖3是表面織物的展開圖。裏面織物12和過濾器13也具有與表面織物11相同的形狀。Figure 3 is an expanded view of the surface fabric. The inner fabric 12 and the filter 13 also have the same shape as the surface fabric 11 .

表面織物11的形狀是，其上端部1a在前中心M處的左右是連續的，而在上端部1a下方在前中心M處的左右是分離的。The shape of the surface fabric 11 is such that its upper end portion 1 a is continuous left and right at the front center M, and is separated at the front center M below the upper end portion 1 a.

左右分離的織物部分w1和w2之間的分開距離d朝向底部而變長。因此，前中心M側的織物部分w1、w2的側端1b具有彎曲形狀。The separation distance d between the left and right separated fabric portions w1 and w2 becomes longer toward the bottom. Therefore, the side ends 1b of the fabric portions w1, w2 on the front center M side have curved shapes.

首先，將過濾器13層疊在表面織物11上。在層疊過濾器13的情況下，表面織物11的織物部分w1的側端1b和織物部分w2的側端1b重疊以彼此面對。此時，過濾器13的織物部分w1和織物部分w2分別位於重疊的表面織物11的兩側。First, the filter 13 is laminated on the surface fabric 11 . In the case of the laminated filter 13, the side end 1b of the fabric portion w1 and the side end 1b of the fabric portion w2 of the surface fabric 11 overlap to face each other. At this time, the fabric part w1 and the fabric part w2 of the filter 13 are respectively located on both sides of the overlapping surface fabric 11 .

接著，將層疊的表面織物11的側端1b與過濾器13縫合在一起。為了減少線頭的散線，可採用包縫、曲折縫等針法將側端縫合起來。Next, the side ends 1b of the laminated surface fabric 11 and the filter 13 are sewn together. In order to reduce the loose threads at the end of the thread, stitches such as overlock seam and zigzag seam can be used to sew the side ends together.

當佩戴口罩10時，側端1b處的縫合線位於前中心M處。由於側端1b是彎曲的，因此縫製形成沿前中心M向前凸出的三維形狀。When the mask 10 is worn, the seams at the side ends 1b are located at the front center M. Since the side end 1b is curved, it is sewn into a three-dimensional shape protruding forward along the front center M.

側端1b的縫製方法優選為拉伸縫製。拉伸縫製是通過縫紉機的差動送料機構調整織物的送入量，一邊拉伸織物一邊縫製的方法。The sewing method of the side end 1b is preferably stretch sewing. Stretch sewing is a method of sewing while stretching the fabric by adjusting the feeding amount of the fabric through the differential feeding mechanism of the sewing machine.

拉伸縫製可減少織物因縫製而產生的收縮，並能形成具有張力的自然彎曲的前中心M。此外，可以減少在前中心M周圍的織物中出現的褶皺和凹陷，從而提高設計感。Stretch sewing reduces fabric shrinkage due to sewing and creates a naturally curved front center M with tension. In addition, it is possible to reduce wrinkles and dents occurring in the fabric around the front center M, thereby improving the sense of design.

從避免織物過度拉伸的觀點來看，可以在側端1b的接縫餘量處縫製毛紡帶等防拉伸帶。From the viewpoint of avoiding excessive stretching of the fabric, a stretch-preventing tape such as a woolen tape may be sewn at the seam allowance of the side end 1b.

同樣在裏面織物12中，織物部分w1的側端1b和織物部分w2的側端1b縫合在一起。因此，形成了與表面織物11相同的三維形狀。將形成有三維形狀的表面織物11和裏面織物12重疊，使得沒有接縫餘量的表面在前中心M處彼此面對。Also in the inner fabric 12, the side end 1b of the fabric portion w1 and the side end 1b of the fabric portion w2 are sewn together. Therefore, the same three-dimensional shape as the surface fabric 11 is formed. The surface fabric 11 and the back fabric 12 formed in a three-dimensional shape are overlapped such that the surfaces without seam allowance face each other at the front center M.

此時，表面織物11的接縫餘量在前中心M處向左側或右側傾斜。裏面織物12的接縫餘量在前中心M處朝向與表面織物11的接縫餘量相反的方向傾斜。由於接縫餘量不相互重疊，所以可以減少前中心M處的厚度。At this time, the seam allowance of the surface fabric 11 is inclined to the left or right at the front center M. As shown in FIG. The seam allowance of the inner fabric 12 is inclined at the front center M in a direction opposite to the seam allowance of the surface fabric 11 . Since the seam allowances do not overlap each other, the thickness at the front center M can be reduced.

接著，將伸縮帶14沿表面織物11的上端放置在表面織物11上。表面織物11與裏面織物12在上端和下端與伸縮帶14一起縫合。為了減少斷線，上端和下端的縫製方法可以採用包縫、曲折縫等針法縫製。Next, the stretch belt 14 is placed on the surface fabric 11 along the upper end of the surface fabric 11 . The surface fabric 11 and the inner fabric 12 are sewn together with stretch straps 14 at the upper and lower ends. In order to reduce thread breakage, the sewing method of the upper end and the lower end can be sewn with stitches such as overlock seam and zigzag seam.

當縫合上端和下端時，獲得具有左右開口的筒狀的本體部1。該筒狀的本體部1係內翻，前中心M的縫邊位於本體部1的內側。When the upper and lower ends are sewn together, a cylindrical body portion 1 having left and right openings is obtained. The cylindrical main body 1 is turned inside out, and the hem of the front center M is located inside the main body 1 .

本體部1的左右端向內折疊。結果，當縫合端部時，縫邊可以向內定位。表面織物11的折疊部分和裏面織物12的折疊部分重疊以彼此面對。耳掛部2的膠帶構件設置在折疊部分之間。The left and right ends of the main body part 1 are folded inward. As a result, the seam allowance can be positioned inwardly when the ends are stitched. The folded portion of the surface fabric 11 and the folded portion of the inner fabric 12 overlap to face each other. The tape member of the ear hook portion 2 is disposed between the folded portions.

接著，縫合本體部1的上下左右端，形成縫合線3。例如，縫合線3設置在與端部相隔一定距離例如2mm的位置處。表面織物11和裏面織物12由縫合線3縫合。此外，將帶構件縫合到本體部1以形成耳掛部2。Next, the upper, lower, left, and right ends of the main body portion 1 are sewn together to form suture lines 3 . For example, the suture 3 is provided at a position separated from the end by a certain distance, for example, 2 mm. The surface fabric 11 and the inner fabric 12 are sewn together by a sewing thread 3 . Furthermore, a strap member is sewn to the body portion 1 to form the earhook portion 2 .

可沿前中心M設置縫合線。由於表面織物11和裏面織物12在前中心M處通過縫合線連接，所以可以防止表面織物11和裏面織物12在使用過程中移位。還可以防止口罩10因洗滌而變形。A suture may be placed along the front center M. Since the surface fabric 11 and the inner fabric 12 are connected at the front center M by the sewing thread, the surface fabric 11 and the inner fabric 12 can be prevented from being displaced during use. It can also prevent the mask 10 from deforming due to washing.

圖4是沿著線A-A的剖視圖。線A-A在前中心M處切割本體部1的上端部1a。圖5是沿著線B-B的剖視圖。線B-B在本體部1的上端部1a的下方，在與前中心M正交的方向上被切斷。Fig. 4 is a sectional view along line A-A. Line A-A cuts the upper end portion 1a of the body portion 1 at the front center M. As shown in FIG. Fig. 5 is a sectional view along line B-B. The line B-B is cut in a direction perpendicular to the front center M below the upper end 1 a of the main body 1 .

將表面織物11的上端部1a和裏面織物12的上端部1a重疊並縫合，使得它們的折疊部分彼此面對。由於過濾器13與表面織物11一起被折回，因此在上端部1a處除了伸縮帶14之外的織物的疊置數量至少為六層。The upper end portion 1a of the surface fabric 11 and the upper end portion 1a of the inner fabric 12 are overlapped and sewn so that their folded portions face each other. Since the filter 13 is folded back together with the surface fabric 11, the stacked number of fabrics at the upper end 1a other than the stretch band 14 is at least six layers.

另一方面，在上端部1a的下方，表面織物11和過濾器13重疊兩個的縫邊向右傾斜。該接縫餘量與裏面織物12重疊。因此，在前中心M的左側，總共堆疊了7塊織物。On the other hand, in the lower part of the upper end part 1a, the hem where the top fabric 11 and the filter 13 overlap two is inclined to the right. This seam allowance overlaps the inner fabric 12 . So, to the left of the front center M, a total of 7 pieces of fabric are stacked.

疊置兩片裏面織物12的縫邊向左側傾斜。該接縫餘量層疊在表面織物11和過濾器13上。因此，在右側，總共堆疊了5塊織物。The seam allowances of the overlapping two inner fabrics 12 are inclined to the left. The seam allowance is laminated on the face fabric 11 and the filter 13 . So, on the right side, a total of 5 pieces of fabric are stacked.

如果上端部1a在前中心M處的左右兩側不是連續的，而是以與上端部1a下方的區域相同的方式分開，則折疊的結果是在上端部1a處的織物層數是上端部1a下方區域的兩倍。換句話說，在前中心M的右側，總共堆疊14塊織物，而在左側總共堆疊10塊織物。If the upper end 1a is not continuous to the left and right at the front center M, but separates in the same way as the area below the upper end 1a, the result of the fold is that the number of layers of fabric at the upper end 1a is the upper end 1a double the area below. In other words, on the right side of the front center M, a total of 14 pieces of fabric are stacked, while on the left side a total of 10 pieces of fabric are stacked.

如上所述，根據在上端部1a處左右織物連續的本實施方式，能夠將在上端部1a層疊的織物的個數減半，使織物變薄。較薄的上端部1a容易變形，以適應突出的鼻子和彎曲的臉頰的形狀，並且沿著凹凸不平的臉線黏附。因此，無需在與鼻子接觸的部分設置金屬線等，就能夠提供貼合性優異的口罩10。As described above, according to the present embodiment in which the left and right fabrics are continuous at the upper end 1a, the number of fabrics laminated at the upper end 1a can be halved and the fabric can be thinned. The thinner upper end portion 1a is easily deformed to fit the shape of a protruding nose and curved cheeks, and adheres along uneven face lines. Therefore, it is possible to provide the mask 10 with excellent fit without providing a metal wire or the like at the portion in contact with the nose.

上端部1a的面積可以適當設定。例如，上端部1a是距離本體部1的上端約0.5~3cm的區域。其中，上端部1a優選為距上端0.7~1.5cm的區域。如果距上端0.7cm以上，容易獲得充分的貼合性；如果距上端1.5cm以下，則容易形成易於呼吸的空間，同時避免過度黏連。The area of the upper end portion 1a can be appropriately set. For example, the upper end portion 1 a is an area approximately 0.5 to 3 cm away from the upper end of the main body portion 1 . Among them, the upper end portion 1a is preferably a region of 0.7 to 1.5 cm from the upper end. If it is more than 0.7cm from the upper end, it is easy to obtain sufficient fit; if it is less than 1.5cm from the upper end, it is easy to form a space that is easy to breathe while avoiding excessive adhesion.

表面織物11、過濾器13和裏面織物12的尺寸可以通過考慮上端部1a的區域的尺寸和接縫餘量的尺寸來確定。The dimensions of the surface fabric 11, the filter 13 and the inner fabric 12 can be determined by considering the dimensions of the area of the upper end 1a and the dimensions of the seam allowance.

如上所述，根據本實施方式，表面織物11、裏面織物12和過濾器13具有上端部1a的左右是連續而在上端部1a下方是左右分離的形狀。在口罩10中，左右分開的織物部分w1和w2被縫合在前中心M處。As described above, according to the present embodiment, the top fabric 11, the back fabric 12, and the filter 13 have a shape in which the left and right sides of the upper end portion 1a are continuous and the left and right sides are separated below the upper end portion 1a. In the mask 10, the left and right divided fabric portions w1 and w2 are sewn at the front center M.

由於在織物沒有左右分離的上端部1a處重疊織物的數量少且薄，因此上端部1a更容易符合突出的鼻子和彎曲的臉頰的形狀，並順著不平整的臉部線條。因此，能夠提供貼合性良好的口罩10。Since the number of overlapping fabrics is small and thin at the upper end 1a where the fabric is not separated left and right, the upper end 1a is more likely to conform to the shape of a protruding nose and curved cheeks, and follow uneven facial lines. Therefore, the mask 10 with favorable fit can be provided.

如果上端部1a較薄，則它變得柔軟，因此當從面臉部取下的口罩10放置在桌子上時，口罩10很容易因自重而折疊。與臉部接觸的口罩10的背面不易露出，因此更衛生。If the upper end portion 1a is thinner, it becomes soft, so when the mask 10 removed from the face is placed on a table, the mask 10 is easily folded by its own weight. The back side of the mask 10 that is in contact with the face is difficult to expose, so it is more hygienic.

另外，在上端部1a設有伸縮帶14。伸縮帶14使本體部1的上端部1a更容易貼合到鼻子和臉頰的曲面上。此外，伸縮帶14增加了張力，這使得上端部1a下方的織物更容易懸垂到前側。由於容易形成口周圍的空間並且由於呼吸引起的黏連減少，使口罩10的佩帶更加舒適。Moreover, the stretchable belt 14 is provided in the upper end part 1a. The elastic band 14 makes it easier to fit the upper end 1a of the main body 1 to the curved surfaces of the nose and cheeks. Furthermore, the stretch strap 14 increases the tension, which makes it easier for the fabric below the upper end 1a to hang to the front side. Since the space around the mouth is easily formed and the adhesion caused by breathing is reduced, the wearing of the mask 10 is more comfortable.

口罩10的本體部1是由針織物製成，可以清洗。即使去除污垢並重複使用，也可以保持衛生。The body part 1 of the mask 10 is made of knitted fabric and can be cleaned. It can be kept hygienic even after removing dirt and reusing it.

儘管上面已經描述了本發明的優選實施例，但本發明並不局限於這些實施例，在本發明的範圍內，各種變化和改變是可能的。Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various changes and modifications are possible within the scope of the present invention.

例如，表面織物11的上端部1a和裏面織物12的上端部1a可以通過熱壓法結合。在熱壓黏合的情況下，織物的邊緣沒有磨損，因此不需要將上端部1a折回以使縫邊位於內側。For example, the upper end portion 1a of the surface fabric 11 and the upper end portion 1a of the inner fabric 12 may be bonded by heat pressing. In the case of thermocompression bonding, the edges of the fabric are not frayed, so there is no need to fold back the upper end 1a to bring the seam allowance on the inside.

因此，上端部1a的重疊織物的數量可以減少到縫製時的一半。由於上端部1a變薄並且與鼻子的密合性提高，因此可以提供具有更好貼合性的口罩10。Therefore, the number of overlapped fabrics of the upper end portion 1a can be reduced to half that of sewing. Since the upper end portion 1a is thinned and the adhesion to the nose is improved, it is possible to provide the mask 10 with better fit.

表面織物11和裏面織物12最好選擇易於熱壓縮的材料，如聚丙烯或其他熱塑性塑料。The surface fabric 11 and the inner fabric 12 are preferably selected from materials that are easy to be thermally compressed, such as polypropylene or other thermoplastics.
