  Accordingly, an object of the present invention is to provide a side sweat removing sheet that is easy to wear and can reliably prevent twisting and shifting.

  The object of the present invention is a side sweat removing sheet comprising a sheet body that absorbs sweat on the front surface side and an adhesive layer provided on the back surface side of the sheet body, wherein the sheet body is flexible. The pressure-sensitive adhesive layer is achieved by a side sweating sheet comprising a plurality of first adhesive portions arranged at intervals in the sleeve-side region. Is done.

  In this side sweat removing sheet, it is preferable that a minimum interval between the adjacent first adhesive portions is 3 to 25 mm.

  Moreover, it is preferable that the shortest distance from the outer edge of the said sleeve side area | region to a said 1st adhesion part is 3-20 mm.

The area of the first adhesive portion is preferably respectively a 15~2500mm ^2.

  It is preferable that the pressure-sensitive adhesive layer further includes a second pressure-sensitive adhesive portion formed in the body side region. In this case, it is more preferable that a plurality of the second adhesive portions are arranged at intervals.

  According to the present invention, it is possible to provide a side sweat removing sheet that is easy to wear and can reliably prevent twisting and shifting.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a back view of an armpit perspiration sheet according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line AA of FIG.

  As shown in FIGS. 1 and 2, the sweat removing sheet 1 includes a flexible sheet body 10 and an adhesive layer 20 provided on the back side of the sheet body 10. The sheet body 10 is configured such that an absorption layer 16 is sandwiched between a front surface layer 12 and a back surface layer 14.

  The absorbent layer 16 is not particularly limited as long as it has water absorbency, and is generally used for sanitary napkins, diapers, sweat-caps, and cage sheets, for example, well-known water-absorbing pulp, water-absorbing polymer, etc. An absorbent material, a fiber structure composed of a woven fabric, a knitted fabric, a nonwoven fabric, a pulp product, or the like can be used. Especially, it is preferable to use the aggregate | assembly (for example, nonwoven fabric) which consists of a natural fiber and a synthetic fiber from the point that texture (feel) is excellent, it is excellent in absorptivity, and there are few drop-off | omission of the raw material from an absorption layer. Examples of natural fibers include cotton, silk, pulp, wool and hemp. Among such natural fibers, cellulose fibers such as cotton and pulp (which are not protein-based components) are preferable from the viewpoint that contact dermatitis such as allergy is unlikely to occur, rash is hardly caused, and absorption is excellent. Examples of the synthetic fiber include nylon fiber, polyethylene fiber, polyester fiber, polyamide fiber, acrylic fiber, polyvinyl alcohol fiber, polypropylene fiber, polyethylene terephthalate fiber, ethylene vinyl acetate fiber, urethane fiber, and acrylic fiber. Moreover, semi-synthetic fibers such as rayon fiber, acetate fiber, and cupra, and blended and mixed products of various fibers can also be used. Of these, synthetic fibers such as ethylene vinyl acetate fiber, polypropylene fiber, polyethylene fiber, polyester fiber, and polyethylene terephthalate fiber, or composite fibers thereof are preferable from the viewpoint of dry feeling, texture, and heat sealability. Examples of the composite fiber include polyethylene / polyester (including polyethylene terephthalate) composite fiber, polyethylene / polypropylene composite fiber, ethylene vinyl acetate / polypropylene composite fiber, etc., and polyethylene / polypropylene from the viewpoint of excellent elastic recovery function (rebound). A composite fiber is more preferable. Furthermore, when a polyethylene / polypropylene composite fiber having a core made of polypropylene fiber whose outer periphery is wrapped with polyethylene is used, the core polypropylene fiber can exhibit an excellent elastic recovery function (rebound) when used. Further preferred.

  Moreover, from the point which can be set as the absorption layer excellent in the resistance and absorption with respect to a shift | offset | difference or breakage, as an aggregate, the ratio of 3: 7 to 7: 3 by weight ratio of natural fibers and synthetic fibers It is preferable to blend with natural fibers and synthetic fibers in a weight ratio of 4: 6 from the viewpoint of excellent absorbability, prevention of falling off of natural fibers from the absorption layer, and excellent touch feeling as a touch. It is more preferable to blend in a ratio of ˜6: 4.

  Further, this natural fiber and synthetic fiber are mixed, and the resulting mixture is heated at a temperature 10 to 50 ° C., preferably 20 to 40 ° C. higher than the softening point of the synthetic fiber (for example, polyethylene / polypropylene composite fiber as the synthetic fiber) When the heat treatment is performed, the synthetic fiber is appropriately melted and entangled with the natural fiber, and more excellent absorbency, more fun than ever. It is particularly preferable because it can be made into an absorbent layer (texture) that does not fall off natural fibers. Moreover, it is preferable that the thickness of a synthetic fiber is 1.0-5.0 dtex, and it is more preferable that it is 2.0-3.5 dtex. If the thickness of the synthetic fiber is less than 1.0 decitex, the natural fiber cannot be satisfactorily intertwined with the natural fiber, and the natural fiber tends to fall off from the absorbent layer. Moreover, when 5.0 decitex is exceeded, the obtained absorption layer will become hard, and there exists a tendency for it to be inferior in terms of stiffness and wearability.

Basis weight of the stack constituting the absorbent layer 16 is, from the viewpoint of balance between the discomfort to the water retention capacity and the skin, it is preferable to set the 20 to 150 g / ^{m 2,} to set a 40 to 120 g / ^{m 2} Is more preferable.

  Further, the surface layer 12 plays a role of softly contacting the skin and protecting the flexible absorbent layer 16. Examples of the surface layer 12 include a sheet-like or film-like fiber structure made of a woven fabric, a knitted fabric, a nonwoven fabric, a pulp product, or the like. Of these, non-woven fabrics are preferred from the viewpoint of texture (feel), irritation to the skin, and absorbability. Examples of fibers constituting such a fiber structure include natural fibers and synthetic fibers, and these can be used alone or in combination as a fiber structure having desired properties. Examples of natural fibers and synthetic fibers include the same fibers as those used as a raw material for the absorbent layer 16. These fiber structures are not particularly limited in shape, but if they are mesh and / or embossed patterns, the area of contact with the skin is reduced and the feeling of adhesion when worn is reduced. This is preferable in that the fluid permeability of body fluids such as spots and sweat is improved, and even a small amount of body fluids can easily reach the absorption layer 16. In addition, it is preferable to perform embossing so that the hollow end part of the recessed part of the processed surface material may open. Moreover, when it is not set as the said mesh shape and / or a raised pattern, it is preferable at the point from which the frictional force to skin reduces and it becomes difficult to produce a itch and a rash.

  Nonwoven fabrics include wet papermaking, dry papermaking, spunbond, meltblown, latex resin bond, solvent bond, stitchbond, needle punch, spunlace, thermal bond, air-through, airlaid, etc. It can manufacture by the method of. Of these, methods such as the spunlace method, thermal bond method, air-through method, airlaid method, needle punch method, and spunbond method are preferable. Since these methods have a good texture and do not use an adhesive or a solvent, it is applied to the skin. The safety can be increased.

  Further, the fiber structure is preferably subjected to water repellent treatment. Although the water repellent treatment can be performed only on one side of the fiber structure, it is preferable that the water repellent treatment is performed on both sides when the target body fluid is a small amount. The double-sided water-repellent treatment can prevent the penetration of body fluid into the fibers of the surface material and the lateral bleeding of the body fluid. As a result, a small amount of body fluid can be efficiently absorbed through the pores of the surface material (fiber structure). Can be reached. That is, according to the absorbent sheet of the present invention provided with the surface material subjected to the double-sided water repellent treatment, it is possible to allow quick absorption even when the amount of body fluid is small. The water-repellent treatment can be performed by preparing a sheet-like fiber structure (surface material) and then subjecting both surfaces of the structure to a water-repellent treatment. Or you may employ | adopt any of the method of preparing in a film form.

  The water repellent treatment method is not particularly limited, and usual methods can be widely adopted. Specific examples include a method using a water repellent treatment agent such as silicon oil, fluororesin, methylhydrogenpolysiloxane or an oil containing these components, preferably silicon oil, fluororesin, methylhydrogenpolysiloxane. Is a method of processing fibers using a water repellent treatment agent.

In addition, the basis weight of the fiber structure used for the surface layer 12 is preferably set to 10 to 60 g / m ² from the viewpoint of a balance between fluid permeability and reduction in discomfort to the skin, and is preferably ²⁰ to 50 g / m ^2. it is more preferably set to m ^2.

  A method for bonding the surface layer 12 and the absorbent layer 16 is not particularly limited, but a water-soluble adhesive (for example, an acrylic water-soluble adhesive) or a water-insoluble adhesive (for example, a rubber-based hot melt, an olefin-based hot). It can be adhered by an adhesive such as a melt.

  The back layer 14 prevents the sweat absorbed by the absorbent layer 16 from flowing out. The material of the back layer 14 is preferably polyethylene, but an appropriate material such as polyester, polyvinyl alcohol, polypropylene, nylon, cellophane, vinylon, or vinyl chloride can be used as necessary. In addition, when an inorganic material such as calcium carbonate powder is kneaded with these materials and then biaxially stretched, water (air) can be permeated without permeating bodily fluids such as sweat, thereby reducing discomfort due to stuffiness or the like. In addition, when uniaxial stretching is performed when inorganic materials such as calcium carbonate are not used, it is possible to reliably prevent sweating on clothing even when a large amount of sweat is applied. It is preferable.

  Furthermore, the thickness of the back layer 14 is preferably set to 10 to 50 μm from the viewpoint that the absorbed body fluid is not permeated and it is difficult to feel uncomfortable at the time of wearing.

  The sheet body 10 is not necessarily limited to the above configuration, and includes, for example, a deodorant between one or both of the absorbent layer 16 and the surface layer 12 and between the absorbent layer 16 and the back surface layer 14. A layer may be interposed. Moreover, the sheet | seat main body 10 should just be provided with the absorption layer 16, and it is also possible to comprise without providing the one or both of the surface layer 12 and the back surface layer 14. FIG.

  The material of the pressure-sensitive adhesive layer 20 is not particularly limited as long as it can be applied to clothes or the like. For example, a water-soluble adhesive (for example, an acrylic water-soluble adhesive) or a water-insoluble adhesive (for example, a rubber-based adhesive). Examples thereof include hot melts and olefinic hot melts). Among these, a water-insoluble adhesive is preferable, and a rubber-based hot melt is more preferable from the viewpoint of superior adhesive strength to clothes compared to other pressure-sensitive adhesives. Use of a rubber-based hot melt makes it easy to adjust to the bonding site, so it does not restrain the stretch of clothes (it can reduce the feeling of tension). For this reason, in the present invention in which play is provided between the respective adhesive portions, dropping off from clothes and misalignment can be effectively reduced by such a synergistic effect with the properties of the rubber-based hot melt.

  Further, the adhesive strength of the pressure-sensitive adhesive layer 20 is a strength that can withstand practical use, that is, the peel strength is preferably 80 gf or more, more preferably 80 to 300 gf, and even more preferably 100 to 250 gf. When the peel force is less than 80 gf, the adhesive strength is weak, and the side sweat-repellent sheet tends to fall off from misalignment and clothing. In addition, when peel force exceeds 300 gf, there exists a tendency for the adhesive residue to clothing to be produced.

Peeling force is preferably obtained by dividing the sheet body 10 into a sleeve side region and a body region, and cutting out and preparing all of the divided adhesive parts, and a white cloth cotton (Kanakin 3 for JIS dyeing fastness test). No.) is measured by a 180 degree peeling test using a tensile tester. Specifically, after bonding the adhesive part of the test piece and the attached white cloth cotton (Kanakin No. 3) for JIS dyeing fastness test, a load of 35 g / m ² is applied for 30 seconds, the load is removed, and the temperature is 35 ° C. Leave in an environment of -40 ° C and 75% humidity for 1 to 2 hours, in an environment of 20 ° C and 50% humidity for another 30 minutes. Further, a part of the test piece is peeled off slightly, and the measured value when it is pulled at a speed of 300 mm / min with a tensile tester (Shimadzu AGS-H) is processed and judged by the average of convex points.

  When the adhesive part of the sleeve side region and the body side region fits in the 60 mm x 120 mm JIS dyeing fastness test attached white cloth cotton (Kanakin No. 3), the 60 mm x 120 mm JIS dyeing fastness test attached white cloth cotton ( Using Kanaki No. 3), the peel force due to 180-degree peeling is measured at a test piece width of 60 mm and a peeling direction of 120 mm.

When the pressure-sensitive adhesive part exceeds the area of the test piece of 60 mm × 120 mm, the test is performed using the attached white cloth cotton (Kanakin No. 3) for JIS dyeing fastness test having a size that can cover the pressure-sensitive adhesive part. The test piece width (test piece width w) at that time is measured by the above test method as the width of the attached white cloth cotton (Kanakin No. 3) for JIS dyeing fastness test having a size capable of covering the adhesive part. The measured value is a measured value m obtained by performing the following processing on the measured value s measured with the test piece width w.
* When the adhesive part does not fit in the 60 mm x 120 mm test piece Measurement m = Actual measurement s x Test piece width w / 60 mm
As shown in FIG. 1, the side sweating sheet according to the present embodiment has an outer edge in which the sheet main body 10 is formed in a smooth curved shape, and the sleeve side region 4 and the body side region via a straight line connecting the constricted portions. It is divided into 6. Here, the sleeve side region 4 and the body side region 6 are divided by a groove (boundary line) 2 formed on a straight line connecting the constricted portions in the present embodiment, but the boundary is bent and deformed at the time of wearing. It does not necessarily need to be clear in appearance, such as a portion that naturally bends when given, and refers to a region intended to be attached to the sleeve side and the body side, respectively.

  The pressure-sensitive adhesive layer 20 includes a plurality of first pressure-sensitive adhesive portions 20 a arranged at intervals in the sleeve-side region 4 and a plurality of second pressure-sensitive adhesive portions 20 b arranged at intervals in the body-side region 6. It is covered with release paper (not shown) that covers the back side of the sleeve side region 4 and the body side region 6.

  The shape of the first adhesive portion 20a and the second adhesive portion 20b is a rectangular shape in this embodiment, but in addition, various shapes such as a dot shape, a circular shape, a triangular shape, a square shape, a rod shape, and a spiral shape are available. Is possible. Further, the arrangement of the first adhesive portion 20a and the second adhesive portion 20b is preferably bilaterally symmetrical with respect to a center line extending in a direction orthogonal to the boundary line 2 between the sleeve side region and the body side region. It is not limited to this.

  The side sweating sheet having the above configuration peels off the release paper (not shown) covering the adhesive layer 20 and bends at the boundary line 2 between the sleeve side region and the body side region, and the first adhesive portion 20a and the second adhesive member. By sticking the portions 20b to the sleeves of the clothes and the inner surface of the body, the surface side of the sheet main body 10 comes into contact with the entire side as it covers the clothes.

  The side sweating sheet of the present embodiment has a plurality of first adhesive portions 20a and second adhesive portions 20b that are spaced apart from each other in the sleeve side region 4, so that the clothes expand and contract or deform due to various movements. In addition, the non-adhesive portion of the sheet body 10 corresponding to this interval can be freely deformed. As a result, the restraining force of the clothes associated with the attachment of the sweat removing sheet can be eased, and it is possible to prevent the clothes from being stretched and the sweat removing sheet from being displaced or twisted. In addition, by providing a space between the adhesive parts by providing an interval, the possibility of adhesion between the adhesive parts and the possibility of fingers sticking to the adhesive part can be reduced, and a sweat removing sheet is attached to the clothes. It becomes easy to do.

  In the sleeve side region 4, when the minimum interval between the plurality of first adhesive portions 20a (the linear distance between the closest locations) is shortened, the play portion between the adhesive portions is reduced, causing deviation or slippage. On the other hand, if the minimum distance is too long, the non-adhesive part (playing part) becomes too much and causes twisting and shifting, so 3 to 25 mm is preferable, and 5 to 15 mm is more preferable. The preferable numerical range of the minimum interval is the same for the second adhesive portion 20b.

  Further, if the shortest distance from the outer edge of the sleeve side region 4 to each first adhesive portion 20a is too short, it is difficult to peel the release paper from the adhesive layer 20, and the finger adheres to the first adhesive portion 20a. Because it becomes easy, it becomes difficult to wear the sweat-absorbing sheet 1, but if it is too long, that is, if the non-adhesive part (playing part) from the outer edge to the adhesive layer 20 increases, 3 to 20 mm is preferable, and 5 to 15 mm is more preferable. The outer edge of the sleeve side region 4 is a demarcation line of the sleeve side region 4 excluding the boundary line 2 between the sleeve side region and the body side region. The preferable numerical range of the shortest distance is the same for the second adhesive portion 20b.

Further, if the area of each first adhesive portion 20a is too small, it is necessary for the user to carefully attach the sweat-removing sheet to the clothes when wearing it, and the sweat-removing sheet attached because sufficient adhesive strength cannot be obtained. On the other hand, when 1 becomes easy to drop off, if it is too large, the portion where the expansion and contraction and deformation of the clothes are restricted becomes large and it becomes difficult to wear, so 15 to 2500 mm ² is preferable, and 300 to 2000 mm ² is more preferable. The preferable numerical range of the area is the same for the second adhesive portion 20b.

  In the present invention, the shape of the sweat-absorbing sheet is not particularly limited, and may be any shape such as a square shape, a circular shape, a substantially elliptical shape, an elliptical shape, and a saddle shape. In addition, a saddle shape is preferable from the viewpoint of misalignment and prevention of falling off.

Moreover, in this invention, if the area of a perspiration removal sheet can be mounted | worn to a side part, it will not specifically limit, However, 40-270 cm < ² > is preferable, 55-190 cm < ² > is more preferable, 70-170 cm < ² > is further more preferable.

The area of the sleeve-side region is preferably 10cm ² ~120cm ^2, more preferably 15cm ² ~90cm ^2, more preferably 20cm ² ~80cm ^2. Area of the body-side region is preferably 30cm ² ~150cm ^2, more preferably 40 cm ² 100 cm ^2, more preferably 50cm ² ~90cm ^2.

  As mentioned above, although one Embodiment of this invention was described, as shown in the Example mentioned later, about the 2nd adhesion part 20b, it is not necessarily required to provide two or more, and may be single. Further, even when the second adhesive portion 20b is not provided at all, the body side region 6 of the sweat-absorbing sheet 1 is suspended so that the lower end becomes a free end by sticking the first adhesive portion 20a to the clothes. Therefore, it is possible to prevent the sweat-removing sheet 1 from falling off while enabling comfortable wearing.

  Further, the perspiration sheet of the present embodiment has a side part of the sheet body by providing a difference in thickness between the top and the periphery of the sheet body 10 such as providing a seal part that is thermocompression bonded to the periphery of the sheet body 10. Since the area in contact with the sheet can be reduced, a sense of incongruity caused by friction between the seat body and the side portions can be reduced.

  Furthermore, the surface layer 12 and / or the absorbent body 16 is impregnated with a fragrance, the function of masking the odor of sweat by the fragrance of the fragrance, and the cooling sensation component such as menthol is impregnated to give the user a cool feeling. A function for improving the image quality may be added.

  In addition, the sweat-absorbing sheet of this embodiment is particularly suitable for sweating of the side parts, but it can also be used by sticking to the corresponding part of the inner surface of the clothes for sweating of the back, neck, crotch, etc. Is possible.

  Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples.

  18 example samples (Examples 1 to 18) in which the arrangement of the pressure-sensitive adhesive layer 20 was changed using the sheet body 10 having the three-layer structure (surface layer, absorption layer and back layer) shown in the above embodiment in common Three comparative example samples (Comparative Examples 1 to 3) were prepared and subjected to sensory evaluation when mounted on the side.

  The evaluation is performed on three women with different body shapes, and the average value of the three grades (1 to 5 points) for each of the items “ease of wearing” and “displacing in use”. (Rounded off to the nearest whole number) for total evaluation.

Tables 1 and 2 show configurations and evaluation results of Examples and Comparative Examples, respectively. Here, although the pressure-sensitive adhesive of Comparative Example 3 is one block, it exists across each region on the sleeve side and the body side, so that the pressure-sensitive adhesive area of one block is halved.
The configurations of Examples 1 to 18 correspond to FIGS. 3A to 3R, respectively, and the configurations of Comparative Examples 1 to 3 correspond to FIGS. 4A to 4C, respectively. The corresponding area corresponds to the adhesive.

  The size of the sheet main body 10 in FIGS. 3 and 4 is 125 mm × 125 mm for the rectangular shape, and 97 mm × 96 mm for the eleventh, twelfth, and 16th examples of the bowl-shaped one.

As is clear from this example, the adhesive layer has a plurality of first adhesive portions arranged at intervals in the sleeve-side region, so that it is easy to wear and reliably twists and shifts. It can be seen that it can be prevented.

  Further, the minimum distance between adjacent adhesive portions, the shortest distance from the outer edge of the sleeve side region to the first adhesive portion, and the area of the first adhesive portion are each defined in a preferable range, and the second adhesive portion is provided in the body side region. By forming, in addition to the above effects, the effect of ensuring the prevention of falling off is obtained. Specifically, it is as follows.

In Example 1, the area of each first adhesive portion 20a was 15 mm ² , and the first adhesive portion 20a was superior in ease of mounting compared to Example 17 in which the area of the first adhesive portion 20a was 10 mm ² .

  In Example 2, since the plurality of first adhesive portions 20a are arranged in the sleeve side region, it is easier to attach compared to Comparative Example 1 in which the adhesive portion is single, and it is difficult for deviation or deviation to occur.

Further, in Example 3, by setting the area of the first adhesive portion 20a to 2400 mm ² , better mountability was obtained compared to Example 18 in which the area of the first adhesive portion 20a was 2700 mm ² .

  In Examples 4 to 10, in addition to the first adhesive part 20a of Example 2, a second adhesive part 20b is added.

Example 4 is provided with one second adhesive part 20b, Example 5 is provided with two second adhesive parts 20b, and Example 6 has a small area of 15 mm ² . A number of two adhesive portions 20b are provided. In any case, better results were obtained with respect to ease of wearing and deviation than in Comparative Example 2 in which each of the first adhesive portion 20a and the second adhesive portion 20b was one.

In Example 7, the second adhesive portion 20b having an area of 2700 mm ² was provided, and although it was inferior to Example 4 in terms of ease of mounting, it was generally good.

  In Example 8, the interval between the adjacent first adhesive portions 20a and the second adhesive portions 20b in Example 5 is narrowed to 1 mm, and this is an example in terms of ease of mounting and misalignment. Although it was inferior to 5, it was good overall.

  In Example 5, the interval between the adjacent first adhesive portions 20a and the second adhesive portions 20b is expanded to 25 mm in Example 5, and in this case as well, it is inferior to Example 5 due to ease of mounting. However, overall it was good.

  In Example 9, the interval between the second adhesive portions 20b was expanded to 35 mm in Example 9, and although it was inferior to Example 9 in terms of displacing, it was generally good.

  In Examples 11, 12 and 16, the bowl-shaped sheet body 10 is provided with a plurality of first adhesive portions 20a and second adhesive portions 20b, respectively, which are comprehensive from the viewpoint of ease of mounting and misalignment. It was excellent.

  In Example 13, a large number of first adhesive parts 20a and second adhesive parts 20b are provided, and as in Example 5, good effects are obtained in terms of ease of mounting and prevention of falling off. On the other hand, in Comparative Example 3 corresponding to the configuration in which the gap between the first adhesive portions 20a and the gap between the second adhesive portions 20b in Example 13 was filled with the adhesive, the adhesive layer became too large and mounted. Sometimes it was inevitable that the finger would stick to the adhesive, making it very difficult to wear.

  In Example 14, the shortest distances from the outer edge to the first adhesive part and the second adhesive part were each shortened to 1 mm, and it was difficult to remove the release paper. Although it was inferior to 5, it was good overall.

  In Example 15, the shortest distances from the outer edge to the first adhesive part and the second adhesive part were each increased to 20 mm, which is inferior to Example 5 in that it is likely to cause misalignment and dropout. It was good.

  As a reference, for Examples 1 to 18, sensory evaluation was performed from the viewpoint of easy removal (subject and evaluation method are the same as above), the minimum interval between adjacent adhesive portions, the outer edge of the sleeve side region By defining the shortest distance to the first adhesive part and the area of the first adhesive part within a preferable range, and forming the second adhesive part in the body side region, an effect of ensuring the prevention of falling off is obtained.

In Example 1, the area of each first adhesive portion 20a is 15 mm ² , and in this case, a certain degree of drop-off prevention effect is obtained, whereas the number of the first adhesive portions 20a is the same and the area is the same. Example 17 which is 10 mm ² was easy to drop off after mounting.

  In Example 4, by providing one second adhesive portion 20b, the effect of preventing dropout was better compared to Example 2.

  In Example 5, two second adhesive portions 20b were provided, and the effect of preventing dropout was better than that in Example 4.

Example 6, by area provide a large number of the second adhesive portion 20b of 15 mm ^2, in spite area is small, the falling-off prevention effect of the same level as in Example 4 were obtained.

  In Example 8, the interval between the adjacent first adhesive portions 20a and the second adhesive portions 20b in Example 5 is narrowed to 1 mm. By reducing the distance between the first adhesive portions 20a and the second adhesive portions 20b, the non-adhesive portion of the sheet main body 10 is not easily deformed when the clothes are stretched or deformed. Dropout was easy to occur, but overall it was good.
