Description

  The present invention relates to a side sweat removing sheet.

  In order to prevent sweat permeation of clothes and discomfort caused by sweat, a sweat-removing sheet that absorbs sweat by bringing it into contact with a place such as a side where it is easy to sweat has been conventionally used. Such sweat removing sheets include a type that is used by being attached to clothes, and a type that is used by being applied to the skin. For example, as a type of sweat-removing sheet that is attached to clothes, the adhesive part is provided on the back side opposite to the surface that absorbs sweat, and the folding reference line located at the approximate center of the sheet is attached to the armholes of the clothes. It is used by bending along the part, arranging the sheet so as to straddle the body side and the sleeve side, and affixing to the clothes through the adhesive part (for example, see Patent Document 1).

  The side sweat removing sheet 1 of the present embodiment is of a type that is used by being attached to clothes, and includes a flexible sheet body 2 and an adhesive portion 3 provided on the back surface of the sheet body 2. Yes. The sheet body 2 has a configuration in which an absorption layer 22 is sandwiched between a protective layer 20 and a waterproof layer 21. The sheet body 2 is divided into a first region 2A and a second region 2B with a bending reference line L crossing the sheet body 2 as a boundary. The bending reference line L is located substantially at the center of the sheet body 2 in the present embodiment. In the outer peripheral edge 5 of the sheet body 2, a recess 10 is formed at a position where the bending reference line L abuts. In this embodiment, the recessed part 10 is formed in the both ends of the bending reference line L, respectively, and it forms in the outer periphery 5 so that the two recessed parts 10 may oppose. The bending reference line L extends between the two depressions 10 in a straight line. Further, the sheet main body 2 is formed with a cut 15 extending from the recess 10 toward the inside of the sheet main body 2. In addition, the code | symbol 25 in FIG. 1 is many embossing recessed parts formed in the surface of the sheet | seat main body 2. FIG.

  The absorbent layer 22 is not particularly limited as long as it has water absorbency, and is generally used for sanitary napkins, diapers, sweat-removing sheets, and cage sheets, for example, well-known water-absorbing pulp, water-absorbing polymer, and the like. 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 (texture) is good, 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. In addition, 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, and ethylene vinyl acetate / polypropylene composite fiber. These may be used alone or in combination of two or more. Examples of combinations of two or more types include combinations of cellulosic fibers and composite fibers, and the blending ratio can be, for example, 4: 6 to 8: 2.

Basis weight of the stack constituting the absorbent layer 22 is, from the viewpoint of balance between the discomfort to the water retention capacity and the ^skin, it is preferable to set the ^{20g / m 2 ~150g / m 2} , more preferably 40 g / ^{m 2} to 120 g / ^{m 2,} more preferably from ^{50g / m 2 ~100g / m 2} . The thickness of the absorption layer 22 is desirably 0.5 mm to 40 mm so as to exhibit the above function.

  The protective layer 20 softly contacts the skin and plays a role of protecting the flexible absorbent layer 22. Examples of such a protective layer 20 include a sheet-like or film-like fiber structure composed of a woven fabric, a knitted fabric, a nonwoven fabric, or a pulp product. 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 the natural fiber and the synthetic fiber include the same fibers as those used as the raw material for the absorption layer 22.

  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.

Basis weight of the fiber structure used for the protective layer 20 from the balance between the reduction of discomfort to the sweat-permeable and skin point is preferably set to ^{10g / m 2 ~60g / m 2} , more preferably it is ^{10g / m 2 ~50g / m 2} , more preferably from ^{10g / m 2 ~30g / m 2} . The thickness of the protective layer 20 is desirably 0.1 mm to 20 mm so as to achieve the above function. Note that a plurality of slits, openings, and the like may be formed in the protective layer 20 in order to further increase sweat permeability.

  The method for bonding the protective layer 20 and the absorbent layer 22 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 hot melt, an olefin hot) It can be adhered by melt).

  The waterproof layer 21 prevents the sweat absorbed by the absorbent layer 22 from flowing out to the outside. Polyethylene is preferably used as the material of the waterproof layer 21, but an appropriate material such as polyester, polyvinyl alcohol, polypropylene, nylon, cellophane, vinylon, vinyl chloride, or the like 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 vapor (air) can be permeated without permeating sweat, so that discomfort due to stuffiness or the like can be reduced. In addition, when an inorganic substance such as calcium carbonate is not used, uniaxial stretching can reliably prevent sweating on clothes even when a large amount of sweat is applied. . Moreover, liquid-impermeable nonwoven fabrics, such as SMS, can also be used.

The basis weight of the waterproof layer 21 is 2 g / m ^{2 in} terms of a balance between preventing the sweat absorbed by the absorbent layer 22 from flowing out and not impairing the flexibility of the side sweat removing sheet 1 as a whole. is preferably set to to 50 g / ^{m 2,} more preferably ^{10g / m 2 ~50g / m 2} , more preferably from ^{20g / m 2 ~40g / m 2} . The thickness of the waterproof layer 21 is preferably set to 10 μm to 70 μm from the viewpoint that it does not transmit absorbed sweat and hardly feels strange when worn.

  The sheet body 2 is not necessarily limited to the above-described configuration. For example, a deodorant or a fragrance is provided between one or both of the absorbent layer 22 and the protective layer 20 and the absorbent layer 22 and the waterproof layer 21. A layer containing may be interposed. Moreover, the sheet | seat main body 2 should just be provided with the absorption layer 22, and it is also possible to comprise without providing one or both of the protective layer 20 and the waterproof layer 21. FIG.

  The pressure-sensitive adhesive used for the pressure-sensitive adhesive part 3 is not particularly limited as long as it can be applied to clothes, skin, etc. For example, a water-soluble adhesive (for example, an acrylic water-soluble adhesive) or a water-insoluble adhesive Examples thereof include adhesives such as rubber hot melt and olefin hot melt. 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). A plurality of adhesive portions 3 may be provided on the back surface of the sheet main body 2 at intervals, or may be provided so as to cover the back surface of the sheet main body 2.

  On the back surface of the sheet body 2, a release sheet (not shown) that protects the adhesive portion 3 until being attached to clothes and can be peeled off from the adhesive portion 3 when attached is attached. The release sheet is formed by applying a release agent to a plastic film, a fiber sheet, paper, or the like, and the release agent side is attached to the adhesive portion 3.

  In the present embodiment, the seat body 2 has an outer peripheral edge 5 formed in a smooth curved shape, and a pair of left and right constricted portions 23 are provided on the outer peripheral edge 5. The constricted portion 23 is gently dented inward from the first region 2A to the second region 2B. Between the two constricted portions 23, a linear groove portion 24 that connects the two constricted portions 23 is provided. In the present embodiment, the groove portion 24 forms a bending reference line L, and the upper and lower portions are separated from each other with the groove portion 24 as a boundary. It is divided into two first regions 2A and second regions 2B. The groove portion 24 is, for example, a position of an armhole portion when the sheet main body 2 is attached to clothes, and the first region 2A is attached to the body side of the clothing and the second region 2B is attached to the sleeve side of the clothing. (Hereinafter, “first region 2A” is referred to as “body side region 2A”, and “second region 2B” is referred to as “sleeve side region 2B”). The body side region 2A has a larger area than the sleeve side region 2B, and can appropriately correspond to the sweating position on the side. In the present embodiment, the bending reference line L is constituted by the groove portion 24, but it is not necessarily clear in appearance such as a portion that naturally bends when subjected to bending deformation at the time of wearing, and the body side region 2A and the sleeve side region 2B are regions intended to be attached to the body side and the sleeve side, respectively. In addition, arc-shaped bent lines 25A and 25B are formed on both the upper and lower sides of the groove 24 (bending reference line L) so as to protrude toward the side away from the groove 24. The bending of the sheet body 2 is facilitated by the bending lines 25A and 25B.

  The recess 10 is formed to be recessed inwardly at the outer peripheral edge 5 of the sheet body 2, and the bending reference line L (groove 24) crosses the sheet body 2 from the recess 10. It extends. The depression 10 is considerably steeper than the constriction 23, and the length between both ends where the depression starts (the length from the farthest end to the end) is set to be considerably shorter than the constriction 23. Has been. Moreover, the hollow part 10 is formed so that opening width may become narrow as it goes inside the sheet | seat main body 2. As shown in FIG. Specifically, it is formed in a substantially semicircular shape in which the opening width L1 at the outer peripheral edge 5 of the sheet body 2 of the recess 10 is 10 mm. As described above, since the depression 10 is formed on the end side of the bending reference line L (groove 24), the body side region 2A is easily moved so as to be twisted with respect to the sleeve side region 2B, and the body side It becomes easy to move so that sleeve side field 2B may twist with respect to field 2A. Therefore, it is easy to put on the sheet body 2 when the sheet body 2 is affixed to the clothes, so that the sheet body 2 can be easily worn and not only when the sheet body 2 is affixed to the clothes but also at the time of use. And the occurrence of misalignment can be prevented. Further, as will be described later, it becomes easier to form the cut 15 in the sheet body 2 at the time of manufacturing, and efficient manufacturing becomes possible. In addition, it is preferable to form the opening width L1 in the outer periphery 5 of the hollow part 10 mentioned above in the range of 3 mm-30 mm, and it is further more preferable to form in the range of 5 mm-15 mm. When the opening width L1 is 3 mm or less, the manufacture of the sheet body 2 is difficult. On the other hand, when the opening width L1 is 30 mm or more, the entire area of the sheet body 2 is reduced, which is preferable from the viewpoint of ensuring sweat absorption performance. Absent. Further, the overall length L3 of the sheet body 2 is about 70 mm to 150 mm, and the opening width L1 at the outer peripheral edge 5 of the recessed portion 10 is about 2% to 40% with respect to the overall length L3 of the sheet body 2.

  The cut 15 is formed in the sheet body 2 so as to extend inward from the recess 10. In the present embodiment, the cut 15 is formed on the bending reference line L in a straight line having a length L2 of 7 mm. Since the seat body 2 has the notches 15 in addition to the recesses 10, the seat body region 2 </ b> A can move more easily with respect to the sleeve side region 2 </ b> B, and the sleeve side region 2 </ b> A It becomes easy to move so that 2B twists further. Therefore, it is possible to prevent twisting and misalignment when the sheet main body 2 is attached to the clothes, so that the sheet main body 2 can be more easily worn and not only when being attached to the clothes but also at the time of use. It is possible to further prevent the occurrence of warping or displacement. The length L2 of the notch 15 is preferably formed in the range of 3 mm to 20 mm, and more preferably in the range of 3 mm to 15 mm. If the length L2 of the cut 15 is 3 mm or less, the ease of movement of the body side region 2A relative to the sleeve side region 2B and the ease of movement of the sleeve side region 2B relative to the body side region 2A may not be ensured. If L2 is 15 mm or more, the sheet body 2 is likely to be divided starting from the notch 15, which is not preferable.

  Next, with reference to FIG. 5, the process of forming the cut 15 in manufacturing the armpit perspiration sheet 1 of the present embodiment will be described. First, each strip-shaped raw sheet of the protective layer 20, the water absorbing layer 22, and the waterproof layer 21 is laminated and bonded to form the strip-shaped sheet body 40. Then, a cut 15 is formed using a blade shape (not shown) at a predetermined position (dotted line portion) corresponding to the final sheet body 2 in the belt-like sheet body 40. At this time, the cut 15 is formed to be slightly longer than the outer peripheral edge of the final sheet body 2. Thereafter, the strip-shaped sheet main body 40 is punched out with a blade mold (not shown) having a shape corresponding to the sheet main body 2 to form the final sheet main body 2 shown in FIG.

  In order to efficiently form a plurality of sheet main bodies 2 from the belt-like sheet main body 40, the sheet main body 2 is punched in a manner adjacent to the left and right lateral directions (the length direction (conveying direction) of the belt-like sheet main body 40). Then, since the space | interval of adjacent sheet | seat main bodies 2 becomes narrow, the space | interval of adjacent notches 15 also becomes narrow. It is preferable to leave an interval of about 5 mm between adjacent notches 15 in order to integrally form a trim 45 generated by punching the sheet body 2. Here, since the recessed part 10 is formed in the sheet | seat main body 2, the space | interval of the sheet | seat main body 2 in the part in which the cut 15 is formed is expanded. Therefore, even when the notches 15 are adjacent to each other, it becomes easy to form the notches 15 while ensuring a desired interval. In addition, by forming the trim 45 integrally, the process of the trim 45 becomes easy and can be manufactured efficiently. Here, when adjacent cuts 15 are connected and integrally formed, the trim 45 generated when the sheet main body 2 is punched is divided into a plurality of parts, so that the processing of the trim 45 becomes complicated, which is not preferable in manufacturing. .

  According to the armpit perspiration sheet 1 having the above-described configuration, the depression 10 formed in the sheet body 2 facilitates movement so that the body side region 2A is twisted with respect to the sleeve side region 2B, and the body side region 2A On the other hand, it becomes easy to move so that the sleeve side region 2B is twisted. In addition, since the incision 15 extending inwardly from the recess 10 is formed in the seat body 2, the body side region 2A can be moved more easily with respect to the sleeve side region 2B, and the body side region 2A. On the other hand, the sleeve-side region 2B is easily moved so as to be twisted. Therefore, it is easy to put on the sheet body 2 when the sheet body 2 is affixed to the clothes, so that the sheet body 2 can be easily worn and not only when the sheet body 2 is affixed to the clothes but also at the time of use. And the occurrence of misalignment can be prevented. Furthermore, the slit 15 can be easily formed at the time of manufacturing the sheet body 2 and can be efficiently manufactured.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible unless it deviates from the meaning. For example, in the above-described embodiment, the recess 10 is formed in a substantially semicircular shape, but is not limited thereto, and may be formed in a triangular shape as shown in FIG. As shown, it may be formed in a rectangular shape or the like. In addition, by forming the recess 10 so that the opening width becomes narrower toward the inside, such as a semicircular shape or a triangular shape, the corner formed by the recess 10 and the notch 15 becomes an obtuse angle and used. Since irritation | stimulation to a person's skin is relieve | moderated, the usability | use_condition of the perspiration sweating sheet 1 improves.

  Moreover, in the said embodiment, although the hollow part 10 and the notch 15 are provided in the both ends of the bending reference line L in the outer periphery 5 of the sheet | seat main body 2, the hollow part 10 and the notch 15 are the bending reference line L. It may be provided only on either one end side.

  Furthermore, in the said embodiment, although the notch 15 is formed on the bending reference line L (groove part 24), what is necessary is just to extend toward the inner side of the sheet | seat main body 2 from the hollow part 10, and it does not necessarily exist on a bending reference line. It may not be formed. Further, the cut 15 is formed in a straight line shape, but may be formed in, for example, a wave shape or a gentle arc shape.

  Furthermore, in the above embodiment, the outer shape of the sheet body 2 is formed in a substantially gourd shape, but various shapes that can be attached to clothes, such as a square shape, a rectangular shape, a circular shape, and a substantially elliptic shape, can do. Moreover, in the said embodiment, although the area of the body side area | region 2A of the sheet | seat main body 2 is made larger than the area of the sleeve side area | region 2B, it is also possible to make it the same area. Further, it is not always necessary to provide the constricted portion 23 in the seat body 2.
