Definitions
- the present invention relates to a waterproof moisture-permeable underwear and a waterproof moisture-permeable liner to be worn on the lower body, and capable of preventing menstrual blood or urinary incontinence from leaking out to outer surface thereof, and avoiding wetness backside thereof.
- underwear intended to prevent menstrual blood leakage or urinary incontinence leakage is constructed by using a fabric having waterproof property or a waterproofed fabric.
- a fabric having waterproof property or a waterproofed fabric in general does not have moisture-permeability, and thus even if it can prevent blood or urine from leaking outside, its inner side may get wet due to vapor or the like and cause a wearer to feel uncomfortable.
- Patent document 1 To eliminate such uncomfortable feeing, for example, sanitary shorts using a fabric having waterproof permeability is proposed in Patent document 1.
- the “gusset” located in the crotch portion of the shorts is constructed in three layers, i.e., an inner layer, a middle layer, and an outer layer.
- the inner layer uses a material having stain-proof property and hygroscopic property.
- the middle layer uses a material having waterproof moisture-permeability (liquid impermeable and vapor permeable property).
- the outer layer uses a material that allows vapor to pass through well and has good looking.
- Such construction enables to prevent menstrual blood or urine from leaking outside, and prevent the inside from getting wet, and to provide a good appearance.
- Patent document 1 microfilm of Japanese utility model application number 1980-138429 (Japanese utility model publication number 1982-60619).
- the sanitary shorts described above are worn directly on the skin, and thus a variety of functionalities, for example, stain-proof property, hygroscopicity, texture (soft feeling), and the like, are required.
- a variety of functionalities for example, stain-proof property, hygroscopicity, texture (soft feeling), and the like.
- the scope of choices for a material for the inner layer is limited.
- the product since the product is shorts, it is necessary to take into account its external appearance to some extent, and thus the degree of choices for a material for the outer layer is also limited.
- the present invention therefore aims to provide a waterproof moisture-permeable underwear and a waterproof moisture-permeable liner by which the scope of choices for a material can be widened, and the waterproofness in the junction areas can be improved so that staining of an outer garment with menstrual blood or urine leaked from undergarment can be surely prevented.
- the invention relates to a waterproof moisture-permeable underwear to be worn between undergarment and an outer garment worn on the lower body.
- the waterproof moisture-permeable underwear according to the invention is characterized in that the underwear is constructed by joining a plurality of two-layered fabric pieces, each of which comprises a base fabric disposed such that it faces the undergarment, and a membrane laminated outside of the base fabric and having waterproof moisture-permeability, in junction areas.
- a material superior to the membrane in texture is selected for the base fabric
- a material superior to the base fabric in welding property is selected for the membrane, and at least one of the junction areas is formed by welding.
- the junction area formed by welding in the waterproof moisture-permeable underwear is formed by welding in such a condition that respective junction allowances of the fabric pieces being adjacent to each other are folded inward and the membranes in the respective junction allowances are brought into contact with each other.
- the junction area formed by welding in the waterproof moisture-permeable underwear is formed by welding in such a condition that respective junction allowances of the fabric pieces being adjacent to each other are extended outward and the base fabrics in the respective junction allowances are brought into contact with each other.
- the junction area formed by welding in the waterproof moisture-permeable underwear is formed by welding in such a condition that one junction allowance of respective junction allowances of the fabric pieces being adjacent to each other is overlaid on the other junction allowance such that the membrane in the one junction allowance is brought into contact with the base fabric in the other junction allowance.
- the junction area formed by welding in the waterproof moisture-permeable underwear is formed by welding in such a condition that respective junction allowances of the fabric pieces being adjacent to each other are folded inward and the membranes in the respective junction allowances are brought into contact with each other, or in such a condition that respective junction allowances of the fabric pieces being adjacent to each other are extended outward and the base fabrics in the respective junction allowances are brought into contact with each other.
- the one junction area is joined to the another junction area with its edge portion being folded in a direction
- the other junction area is joined to the another junction area with its edge portion being folded in a direction opposite to that of the one junction area.
- the junction area formed by welding in the waterproof moisture-permeable underwear is formed by aligning respective end edges of the fabric pieces being adjacent to each other and welding a band of sealing material on the end edges.
- the sealing material in the waterproof moisture-permeable underwear is formed of a cloth same as the fabric piece.
- the sealing material in the waterproof moisture-permeable underwear is formed of a cloth to which hot-melt is applied.
- the junction area of the plurality of fabric pieces to be welded in the waterproof moisture-permeable underwear includes a crotch line and a crotch portion.
- the moisture-permeability of the membrane in the waterproof moisture-permeable underwear increases as temperature rises.
- the fabric piece in the waterproof moisture-permeable underwear has a degree of stretch in one direction and a different degree of stretch in another direction orthogonal to the one direction, and the fabric piece is disposed such that a direction having a higher degree of stretch is horizontal.
- the waterproof moisture-permeable liner is characterized in that the liner is constructed by joining a plurality of two-layered fabric pieces, each of which comprises a base fabric disposed such that it faces the undergarment, and a membrane laminated such that it faces the outer garment and having waterproof moisture-permeability, in junction areas.
- a material superior to the membrane in texture is selected for the base fabric, and a material superior to the base fabric in welding property is selected for the membrane, and at least one of the junction areas is formed by welding.
- the junction area formed by welding in the waterproof moisture-permeable liner is formed by welding in such a condition that respective junction allowances of the fabric pieces being adjacent to each other are folded inward and the membranes in the respective junction allowances are brought into contact with each other.
- the junction area formed by welding in the waterproof moisture-permeable liner is formed by welding in such a condition that respective junction allowances of the fabric pieces being adjacent to each other are extended outward and the base fabrics in the respective junction allowances are brought into contact with each other.
- the junction area formed by welding in the waterproof moisture-permeable liner is formed by welding in such a condition that one junction allowance of respective junction allowances of the fabric pieces being adjacent to each other is overlaid on the other junction allowance such that the membrane in the one junction allowance is brought into contact with the base fabric in the other junction allowance.
- the junction area formed by welding in the waterproof moisture-permeable liner is formed by welding in such a condition that respective junction allowances of the fabric pieces being adjacent to each other are folded inward and the membranes in the respective junction allowances are brought into contact with each other, or in such a condition that respective junction allowances of the fabric pieces being adjacent to each other are extended outward and the base fabrics in the respective junction allowances are brought into contact with each other.
- the junction area formed by welding in the waterproof moisture-permeable liner is formed by aligning respective end edges of the fabric pieces being adjacent to each other and welding a band of sealing material on the end edges.
- the sealing material in the waterproof moisture-permeable liner is formed of a cloth same as the fabric piece.
- the sealing material in the waterproof moisture-permeable liner is formed of a cloth to which hot-melt is applied.
- the junction area of the plurality of fabric pieces to be welded in the waterproof moisture-permeable liner includes a crotch line and a crotch portion.
- the moisture-permeability of the membrane in the waterproof moisture-permeable liner increases as temperature rises.
- the fabric piece in the waterproof moisture-permeable liner has a degree of stretch in one direction and a different degree of stretch in another direction orthogonal to the one direction, and the fabric piece is disposed such that the direction having a higher degree of stretch is horizontal.
- the fabric piece of the waterproof moisture-permeable underwear is constructed by a laminate of a base fabric and a membrane having waterproof moisture-permeability. Therefore, even when menstrual blood or urine penetrates through and leaks out of the undergarment (for example, shorts, sanitary shorts, briefs) worn inside the waterproof moisture-permeable underwear, staining of an outer garment (for example, a skirt, trousers) worn outside of the waterproof moisture-permeable underwear with the urine or menstrual blood can be surely prevented.
- the underwear allows vapor or the like inside the underwear to pass through to outside, and prevents the inside from getting wet.
- an outer garment is worn outside of the waterproof moisture-permeable underwear, unlike the case used for such an outer garment as a raincoat.
- the membrane itself is covered by the outer garment even if the membrane is disposed outside of the base fabric. Therefore, it is not necessary to provide a specific layer for protecting the surface of the membrane or a specific layer for making the membrane look good.
- the underwear it is possible to construct the underwear by lightweight, two-layered fabric pieces each of which comprises a base fabric and a membrane laminated thereon.
- the scope of choices for a material for the base fabric disposed inside is wider than that of the membrane, and thus the feeling when worn can be improved by selecting a material of nice and soft texture for the base fabric.
- the waterproof moisture-permeable underwear is worn on undergarment. However, depending on the size or shape of the undergarment, the waterproof moisture-permeable underwear may directly contact with the skin, and therefore it is desirable that the base fabric, which is disposed inner side of the underwear, have good texture.
- respective junction allowances of the fabric pieces being adjacent to each other are folded inward and welded in such a condition that the membranes having superior welding property are brought into contact with each other, and thus good welding can be performed.
- the junction area is not exposed when worn and thus a good-looking can be obtained.
- respective junction allowances of the fabric pieces being adjacent to each other are extended outward and can be welded in such a condition that the base fabrics are brought into contact with each other.
- respective junction allowances of the fabric pieces being adjacent to each other can be welded in such a condition that one junction allowance is overlaid on the other junction allowance and the base fabric is brought into contact with the membrane.
- the thickness of the junction area is the sum of the thicknesses of one fabric and one sealing material only, and thus poor texture due to thicker thickness can be avoided.
- the sealing material is formed of a cloth same as the fabric piece and thus has same functionalities as the fabric piece has. Therefore the portion in which the sealing material is welded can achieve similar functionalities to those achieved by other portions.
- the sealing material is formed of a cloth to which hot-melt is applied. Therefore, the junction area can be readily welded by heating the hot-melt to melt it and cooling it to cure it.
- the leakage of menstrual blood or urine can be surely prevented by welding a crotch line or a crotch portion, since the menstrual blood or urine is likely to leak at these portions.
- the waterproof moisture-permeability of the membrane increases as temperature rises. Therefore, the wetness that tends to occur as temperature rises can be effectively prevented.
- the fabric piece has a higher degree of stretch in horizontal direction, and thus the waterproof moisture-permeable underwear can be easily worn and taken off, and the fit feeling or the mobility when worn can be improved.

- the underwear 11 is formed in a roughly truncated cone, skirt-like shape by joining two fabric pieces A, A each cut into a predetermined shape, in other words, a front panel 12 and a back panel 13 , in a junction area 11 A on the left side and in a junction area 11 B on the right side.
- the front panel 12 is formed into a roughly trapezoid, and long bands of junction allowances 12 a, 12 b each folded inward are provided roughly vertically at both edge portions on the right and left thereof.
- the back panel 13 is also formed similarly into a roughly trapezoid, and long bands of junction allowances 13 a, 13 b each folded inward are provided roughly vertically at both edge portions on the right and left thereof.
- the front panel 12 and the back panel 13 are shaped into the skirt-like underwear 11 by constructing integrally such that the junction allowance 12 a, 13 a on the left side are joined together to form the junction area 11 A, and the junction allowance 12 b, 13 b on the right side are joined together to form the junction area 11 B.
- the upper edge of the underwear 11 is formed annularly, and, for example, elastic 11 a may be sewn at the upper edge along the periphery in order to prevent the underwear 11 from slipping down when worn.
- the lower edge of the underwear 11 is also formed annularly, and decorative lace 11 b is provided at the lower edge roughly along the periphery.
- a decorative ribbon 11 c is attached at a front upper edge of the underwear 11 .
- Portions other than the elastic 11 a , the lace 11 b , the ribbon 11 c , etc. of the skirt-like underwear 11 constructed as described above are formed of the fabric piece A having waterproof moisture-permeability.
- the fabric piece A having waterproof moisture-permeability is a fabric that does not allow liquid to pass through, but allows vapor to pass through.
- As the fabric piece A having such waterproof moisture-permeability for example, GORE-TEX (Registered trademark) Fabrics manufactured by Japan Gore-Tex Inc., OMNI-TECH manufactured by Columbia Sportswear Company, DRYTEC (registered trademark) manufactured by MontBel Co. Ltd., c_change (registered trademark) from Schoeller, etc are known.
- c_change is superior in (1) waterproof moisture-permeability, and (2) by which lightweight can be achieved, and has (3) good texture (soft feeling), (4) stretch, (5) breathability, windproof property, and (6) good welding property. Having such functionalities, c_change can be preferably used as the fabric piece A for making the underwear 11 of this embodiment, the underwear 21 of the second embodiment, the underwear 31 of the third embodiment, the liner 41 of the fourth embodiment, the liner 51 of the fifth embodiment.
- the fabric piece A is c_change, however, regarding waterproof moisture-permeability, other than c_change, for example, GORE-TEX (Registered trademark) Fabrics or the like may also be used as the fabric piece A, of course.
- GORE-TEX Registered trademark
- the fabric piece A is constructed by a base fabric (base) B and a membrane (thin film) C as shown in FIG. 2A .
- the fabric piece A is a two-layered (two layer structure) fabric piece constructed by laminating the membrane C having waterproof moisture-permeability on one surface of the base fabric B.
- the fabric piece A contains 30 wt % nylon (base fabric B), and 70 wt % polyurethane (membrane C). By adopting such constituents, the fabric piece A achieves waterproof moisture-permeability. As long as the base fabric B surely supports the membrane C and does not disturb the waterproof moisture-permeability of the membrane C, a synthetic resin other than nylon, or even cotton or the like can also be used as the base fabric B.
- the underwear 11 in this embodiment uses two-layered fabric pieces A, lightweight can be sought compared with those that use general three-layered fabric pieces.
- a typical example for a garment constructed by a waterproof moisture-permeable material is a raincoat. If the membrane of a raincoat is damaged or peeled, it may allow rain water to enter therefrom. To protect the membrane, therefore, a protecting layer is provided outside the membrane. In addition, a layer for improving the texture (soft feeling), for example, is provided inside the membrane. In other words, a raincoat in general is formed in three layers, and thus the weight tends to be added. There is a two-layered raincoat that does not have an inner layer, however, in this case, a special treatment is provided on the backside of the membrane for improving the texture, and the treatment may increase the cost for creating the fabric.
- the membrane C can be disposed outer side of the fabric piece A, and the base fabric B can be disposed inner side of the fabric piece A.
- a two-layered construction can be achieved, and thus lightweight can be more readily achieved than with a three-layered construction.
- the underwear 11 has a wider scope of choices for a material for the base fabric B.
- the underwear 11 is called underwear, the description herein is based on the premise that undergarment is worn inside. Depending on the size or shape of the undergarment, a portion of the base fabric B that extends over the undergarment may directly contact with the skin of the wearer. Since the base fabric B may contact with the skin as such, a good texture (soft feeling) is required to some extent but not as much as required for the undergarment, and the scope of choices for the material is widened accordingly. As a result, for example, a texture as good as the texture required for the undergarment is not required, and other functionalities can be enhanced (for example, achieving lightweight or improving breathability) accordingly.
- a material superior in texture to at least the membrane C is adopted for the base fabric B. More specifically, a synthetic resin other than nylon can be also used for the base fabric B on the condition that the base fabric B is superior to the membrane C in texture.
- the fabric piece A has stretch, and, as shown in FIG. 2A , for example, the degree of stretch in direction S 1 (one direction) is higher than the degree of stretch in the direction S 2 (other direction) that is orthogonal to the direction S 1 . Therefore in a case where the skirt-like underwear 11 as shown in FIG. 1A is formed by the fabric pieces A having such stretch, it is desirable that the direction S 1 having a higher degree of stretch be placed horizontally (left-right direction) when the front panel 12 and the back panel 13 are cut from the fabric piece A. This enables the underwear 11 to be easily worn and taken off, and the fit feeling or the mobility can be improved when worn.
- FIG. 2B illustrates experimental data on the relation between the temperature of the membrane C and moisture-permeability in a case the fabric piece A is c_change.
- the horizontal axis shows temperatures (degrees centigrade), and the vertical axis shows moisture-permeability (%).
- the polymer structure of the membrane C opens discretely and thus moisture-permeability is improved. This facilitates to allow moisture to escape to outside, and also facilitates to allow excess heat emitted from the body to escape to outside. In contrast, as temperature lowers, the polymer structure of the membrane C tightly aligns and stores heat, and thus heat retention and comfortable moisture-permeability are maintained.
- the membrane C has breathability but still has windproof property. When wind strikes the membrane C, it bounces off air molecules. However, in a case where the static pressure differs between inside and outside of the membrane C, for example, in a case where when the inner temperature rises and the air pressure that includes partial pressure of vapor becomes higher than the outside air pressure, the air (vapor) can escape from inside to outside.
- the fabric piece A is constructed by the base fabric B and the membrane C, and polyurethane is adopted for the material of the membrane C.
- Polyurethane has thermoplastic property, and melts when heated and cures when cooled. Therefore, the fabric piece A can be welded well in such a condition that the membranes C, C made of polyurethane are brought into contact with each other, without sewing that uses a string.
- welding for example, high frequency welding in which the action of high frequency energy causes resin material itself to generate heat from inside, heat welding that heats by the action of thermal conductivity, ultrasonic welding in which ultrasonic energy causes a target material to vibrate and generate a strong frictional heat, and the like.
- ultrasonic welding is preferable.
- the junction of two adjacent fabric pieces A, A is described regarding the welding property, with reference to FIGS. 3A-3D .
- the welding can be similarly used for a case in which one fabric piece A is looped and then a junction area of one edge portion thereof and a junction area of the other edge portion thereof are joined. Therefore, the case in which two fabric pieces A, A are joined is described below.
- FIGS. 3A and 3B illustrate examples in which two fabric pieces A, A are directly joined
- FIG. 3D illustrates two fabric pieces A, A are joined by using a seam tape (sealing material).
- each of the fabric pieces A, A are folded inward to form bands of junction allowances A 1 , A 1 respectively, and these junction allowances A 1 , A 1 are aligned each other and joined to form a junction area D 1 .
- joining may be done by using a general sewing that uses a string or by the welding shown in FIG. 3C .
- the welding can be performed by using, for example, an ultrasonic sewing machine.
- the two fabric pieces A, A are overlaid each other so that their membranes C, C face each other, and the junction areas A 1 , A 1 at their edge portions are inserted between a pair of metal bars M, M. Then, ultrasonic wave is applied to the metal bars M, M.
- junction area D 2 in this case may be formed either by a general sewing that uses a string or the welding shown in FIG. 3C . If welding is used, the welding is performed in such a condition that both of the fabric pieces A, A are inside out, in FIG. 3C . In this case, the base fabrics B, B are joined each other.
- the base fabrics B, B made of nylon have a poorer welding property than the membranes C, C made of polyurethane have, but polyurethane seeps out from the base fabric B, B when welded and achieves the welding.
- Required waterproofness can be sufficiently obtained even in a case, for example, the base fabrics B, B are welded each other by using an ultrasonic sewing machine as long as the conditions for welding are set as appropriate.
- junction allowance Al of one fabric piece A is simply overlaid on the other junction allowance A 1 of the other fabric piece A to form a junction area and then the junction area is welded, and such a junction area may also be adopted.
- This junction area can be adopted when the junction allowances A 1 , A 1 are not curved but linear, and can reduce fabrication cost compared with those in FIGS. 3A and 3B .
- the junction area is welded in such a condition that the membrane C of one junction allowance A 1 is brought into contact with the base fabric B of the other junction allowance A 1 .
- the junction strength of the junction area formed in this manner is smaller than the junction strength of the junction area Dl shown in FIG. 3A but greater than the junction strength shown in FIG. 3B .
- FIG. 3D shows that a junction area D 3 is formed by using a seam tape S. End edges A 2 , A 2 of two fabric pieces A, A are aligned each other to form the junction allowances A 1 , A 1 , and then a band of the seam tape S is welded on the junction allowances A 1 , A 1 .
- a material similar to the fabric piece A in other words, the base fabric B and the membrane C laminated thereon, is used for the seam tape S.
- the base fabrics B, B disposed inner side of the fabric pieces A, A are joined from inside such that with which the membrane C of the seam tape S contacts. This enables the seam tape S to be hidden inside the fabric pieces A, A and not exposed to outside, and thus good-looking can be achieved.
- the junction strength becomes greater than the junction area D 2 in FIG. 3B in which the base fabrics B, B are joined each other.
- a material similar to the fabric piece A for the seam tape S superior functionality the fabric piece A has can be achieved similarly also in the junction area D 3 that includes the seam tape S.
- a material different from the fabric piece A can also be used for the seam tape. In this case, for example, a material having no waterproof moisture-permeability but having superior welding property, high degree of stretch, being thin, and having a greater strength or the like can be selected.
- seam tape S a seam tape to which hot-melt (adhesive that can be heat welding) is applied can also be used.
- hot-melt adhesive that can be heat welding
- two fabric pieces A, A can be joined by heating the hot-melt to melt it and cooling it to cure it.
- the junction area D 1 in FIG. 3A is strongest, and the junction area D 3 in FIG. 3D is stronger than the junction area D 2 in FIG. 3B .
- the welding property of the membrane C being made of polyurethane is better than the welding property of the base fabric B made of nylon.
- the membranes (polyurethane) C, C are joined in the junction area D 1 in FIG. 3A
- the base fabric (nylon) B and the membrane (polyurethane) C are joined in the junction area D 3 in FIG. 3D
- the base fabrics (nylon) B, B are joined the junction area D 2 in FIG. 3B .
- junction area D 1 in FIG. 3A be applied to the underwear 21 (see FIGS. 4A , 4 B), 31 (see FIGS. 6A , 6 B), and the junction area D 2 in FIG. 3B be used for the liner 41 (see FIGS. 7A , 7 B), 51 (see FIGS. 8A-8C ). Since the junction area D 1 in FIG. 3A is folded inward, the area is not seen from outside when used for the underwear 21 , etc. On the other hand, since the junction area D 2 in FIG. 3B is extended outward, the area is not seen from either outside or inside when used for liner 41 , etc.
- the junction area D 3 in FIG. 3D can be alternatively used instead of the junction areas D 1 in FIG. 3A , and D 2 in FIG. 3B .
- the junction area D 3 in FIG. 3D is better than the junction areas D 1 in FIG. 3A and D 2 in FIG. 3B .
- the thickness of the junction areas D 1 , D 2 themselves is two times of the thickness of one fabric piece A, but in actual use they are folded on either one of the fabric pieces A and the thickness becomes substantially three times the thickness of one fabric piece A, and thus the rough feeling will be increased.
- the junction area D 3 in FIG. 3D uses the seam tape S made of a material similar to the fabric piece A, the thickness thereof is almost same as two times of one fabric piece A, and thus the rough feeling can be reduced compared with the three-times thickness.
- the junction area D 1 shown in FIG. 3A is adopted for the junction areas 11 A, 11 B.
- the junction areas 11 A, 11 B of the underwear 11 is located on the left side and the right side of the underwear 11 .
- Such locations are the portions that are not likely to contact with the menstrual blood or urine that penetrates through undergarment (not shown), for example, compared with a case in which the junction area is located in a front portion or back potion of the underwear 11 . Therefore, in the underwear 11 shown in FIGS. 1A , 1 B, the junction areas 11 A, 11 B may be formed by a general sewing that uses a string, instead of welding.
- junction area if a junction area is located near a portion from the crotch to the buttocks of a wearer, or near those portions, i.e., the portions at which menstrual blood or urine can leak, it is required the junction area should be welded in order to ensure waterproofness.
- the junction allowance Al would be a seam allowance.
- the skirt-like underwear 11 as the waterproof moisture-permeable underwear 10 can prevent staining of the outer garment with menstrual blood or urine leaked from the undergarment by using the fabric piece A having waterproof moisture-permeability.
- the fabric piece A such that the base fabric B is disposed inner side and the membrane C is disposed outer side, two-layered construction being lightweight but having good texture (soft feeling) can be achieved.
- the underwear 11 can be smoothly worn and taken off, and can achieve a good fit, prevent wind entrance, and reduce wetness inside.
- a material having a good welding property for the membrane C the welding of the junction area of the fabric piece A can ensure the waterproofness.

- FIG. 6B is a view taken along an arrowed line B-B in FIG. 6A
- the underwear 31 of this embodiment is worn with a higher fit than the underwear 21 of the second embodiment described above. Therefore, the reduction in rough feeling is sought by adopting the junction area D 3 shown in FIG. 3D for junction areas 31 A- 31 D as described later.
- the underwear 31 is constructed by joining two fabric pieces A, A each cut into a predetermined shape, in other words, a left panel 32 (a front panel and a back panel on the left side formed integrally) and a right panel 33 (a front panel and a back panel on the right side formed integrally) in the junction areas 31 A- 31 D.

It is also possible to adopt the junction area D 1 shown in FIG. 3A for any of the junction areas 31 A- 31 D. However, if it is taken into account that the underwear 31 of this embodiment is intended to be worn with a higher fit, it is desirable to adopt the junction area D 3 in FIG. 3D , which causes less rough feeling.
- junction area D 1 shown in FIG. 3A For the junction areas to be welded in the underwear 11 , 21 , 31 described above in the first to third embodiments, basically the junction area D 1 shown in FIG. 3A may be preferably adopted. Since the junction areas in the underwear 11 , 21 , 31 are folded inward and cannot be seen from outside, the junction areas having good-looking and greater junction strength can be formed. In addition, if less rough feeling is desirable even though junction strength decreases to some extent, the junction area D 3 shown in FIG. 3D may be adopted instead.

Description
- The present invention relates to a waterproof moisture-permeable underwear and a waterproof moisture-permeable liner to be worn on the lower body, and capable of preventing menstrual blood or urinary incontinence from leaking out to outer surface thereof, and avoiding wetness backside thereof.
- Conventionally, underwear intended to prevent menstrual blood leakage or urinary incontinence leakage is constructed by using a fabric having waterproof property or a waterproofed fabric. However, such a fabric in general does not have moisture-permeability, and thus even if it can prevent blood or urine from leaking outside, its inner side may get wet due to vapor or the like and cause a wearer to feel uncomfortable.
- To eliminate such uncomfortable feeing, for example, sanitary shorts using a fabric having waterproof permeability is proposed in
Patent document 1. - In the disclosure, the “gusset” located in the crotch portion of the shorts is constructed in three layers, i.e., an inner layer, a middle layer, and an outer layer. The inner layer uses a material having stain-proof property and hygroscopic property. The middle layer uses a material having waterproof moisture-permeability (liquid impermeable and vapor permeable property). The outer layer uses a material that allows vapor to pass through well and has good looking.
- Such construction enables to prevent menstrual blood or urine from leaking outside, and prevent the inside from getting wet, and to provide a good appearance.
- Patent document 1: microfilm of Japanese utility model application number 1980-138429 (Japanese utility model publication number 1982-60619).
- However, the sanitary shorts described above are worn directly on the skin, and thus a variety of functionalities, for example, stain-proof property, hygroscopicity, texture (soft feeling), and the like, are required. As a result, there has been a problem in that the scope of choices for a material for the inner layer is limited. In addition, since the product is shorts, it is necessary to take into account its external appearance to some extent, and thus the degree of choices for a material for the outer layer is also limited.
- For the underwear of this type for which greater importance is placed on waterproofness, even if the material of the fabric piece itself has high waterproofness, menstrual blood or urine may leak from junction areas (connections) between the fabric pieces. It is therefore essential to enhance waterproofness in the junction areas.
- In a case where the sanitary shorts as described above are worn, even if the wearer has high confidence in the waterproofness of the sanitary shorts, the wearer is plagued by concerns, for example, that a larger amount of menstrual blood or a greater amount of wearers movements may possibly cause the blood to leak out of the sanitary shorts and thus an outer garment such as a skirt or trousers may be stained with them. Such mental concerns hang over the wearers head, and may place a great constraint on activities in business or leisure of the wearer.
- Although the problems in sanitary shorts are presented in the foregoing description, there are almost similar problems also in underwear for incontinence.
- The present invention therefore aims to provide a waterproof moisture-permeable underwear and a waterproof moisture-permeable liner by which the scope of choices for a material can be widened, and the waterproofness in the junction areas can be improved so that staining of an outer garment with menstrual blood or urine leaked from undergarment can be surely prevented.

- In accordance with the invention the junction area formed by welding in the waterproof moisture-permeable underwear is formed by welding in such a condition that respective junction allowances of the fabric pieces being adjacent to each other are folded inward and the membranes in the respective junction allowances are brought into contact with each other, or in such a condition that respective junction allowances of the fabric pieces being adjacent to each other are extended outward and the base fabrics in the respective junction allowances are brought into contact with each other. When the fabric pieces being joined in the junction area are joined in another junction area that intersects with these junction areas in such a condition that one of the junction areas and the other junction area continuously converge each other, the one junction area is joined to the another junction area with its edge portion being folded in a direction, and the other junction area is joined to the another junction area with its edge portion being folded in a direction opposite to that of the one junction area.
- In accordance with the invention the junction area formed by welding in the waterproof moisture-permeable underwear is formed by aligning respective end edges of the fabric pieces being adjacent to each other and welding a band of sealing material on the end edges.

- In accordance with the invention the fabric piece in the waterproof moisture-permeable underwear has a degree of stretch in one direction and a different degree of stretch in another direction orthogonal to the one direction, and the fabric piece is disposed such that a direction having a higher degree of stretch is horizontal.
- In accordance with the invention also relates to a waterproof moisture-permeable liner attached to an inner portion of an outer garment to be worn outside of undergarment worn on the lower body. The waterproof moisture-permeable liner according to the invention is characterized in that the liner is constructed by joining a plurality of two-layered fabric pieces, each of which comprises a base fabric disposed such that it faces the undergarment, and a membrane laminated such that it faces the outer garment and having waterproof moisture-permeability, in junction areas. A material superior to the membrane in texture is selected for the base fabric, and a material superior to the base fabric in welding property is selected for the membrane, and at least one of the junction areas is formed by welding.
- In accordance with the invention the junction area formed by welding in the waterproof moisture-permeable liner is formed by welding in such a condition that respective junction allowances of the fabric pieces being adjacent to each other are folded inward and the membranes in the respective junction allowances are brought into contact with each other.
- In accordance with the invention the junction area formed by welding in the waterproof moisture-permeable liner is formed by welding in such a condition that respective junction allowances of the fabric pieces being adjacent to each other are extended outward and the base fabrics in the respective junction allowances are brought into contact with each other.
- In accordance with the invention the junction area formed by welding in the waterproof moisture-permeable liner is formed by welding in such a condition that one junction allowance of respective junction allowances of the fabric pieces being adjacent to each other is overlaid on the other junction allowance such that the membrane in the one junction allowance is brought into contact with the base fabric in the other junction allowance.
- In accordance with the invention the junction area formed by welding in the waterproof moisture-permeable liner is formed by welding in such a condition that respective junction allowances of the fabric pieces being adjacent to each other are folded inward and the membranes in the respective junction allowances are brought into contact with each other, or in such a condition that respective junction allowances of the fabric pieces being adjacent to each other are extended outward and the base fabrics in the respective junction allowances are brought into contact with each other. When the fabric pieces being joined in the junction area are joined in another junction area that intersects with these junction areas in such a condition that one of the junction areas and the other junction area continuously converge each other, the one junction area is joined to the another junction area with its edge portion being folded in a direction, and the other junction area is joined to the another junction area with its edge portion being folded in a direction opposite to that of the one junction area.
- In accordance with the invention the junction area formed by welding in the waterproof moisture-permeable liner is formed by aligning respective end edges of the fabric pieces being adjacent to each other and welding a band of sealing material on the end edges.
- In accordance with the invention the sealing material in the waterproof moisture-permeable liner is formed of a cloth same as the fabric piece.
- In accordance with the invention the sealing material in the waterproof moisture-permeable liner is formed of a cloth to which hot-melt is applied.
- In accordance with the invention the junction area of the plurality of fabric pieces to be welded in the waterproof moisture-permeable liner includes a crotch line and a crotch portion.
- In accordance with the invention the moisture-permeability of the membrane in the waterproof moisture-permeable liner increases as temperature rises.
- In accordance with the invention the fabric piece in the waterproof moisture-permeable liner has a degree of stretch in one direction and a different degree of stretch in another direction orthogonal to the one direction, and the fabric piece is disposed such that the direction having a higher degree of stretch is horizontal.
- According to the invention, the fabric piece of the waterproof moisture-permeable underwear is constructed by a laminate of a base fabric and a membrane having waterproof moisture-permeability. Therefore, even when menstrual blood or urine penetrates through and leaks out of the undergarment (for example, shorts, sanitary shorts, briefs) worn inside the waterproof moisture-permeable underwear, staining of an outer garment (for example, a skirt, trousers) worn outside of the waterproof moisture-permeable underwear with the urine or menstrual blood can be surely prevented. In addition, the underwear allows vapor or the like inside the underwear to pass through to outside, and prevents the inside from getting wet.
- In addition, an outer garment is worn outside of the waterproof moisture-permeable underwear, unlike the case used for such an outer garment as a raincoat. Thus, the membrane itself is covered by the outer garment even if the membrane is disposed outside of the base fabric. Therefore, it is not necessary to provide a specific layer for protecting the surface of the membrane or a specific layer for making the membrane look good. As such, it is possible to construct the underwear by lightweight, two-layered fabric pieces each of which comprises a base fabric and a membrane laminated thereon.
- Furthermore, the scope of choices for a material for the base fabric disposed inside is wider than that of the membrane, and thus the feeling when worn can be improved by selecting a material of nice and soft texture for the base fabric. The waterproof moisture-permeable underwear is worn on undergarment. However, depending on the size or shape of the undergarment, the waterproof moisture-permeable underwear may directly contact with the skin, and therefore it is desirable that the base fabric, which is disposed inner side of the underwear, have good texture.
- In addition, by using welding to form the junction area of the fabric pieces, the leakage of menstrual blood or urine from the junction area can be surely prevented.
- Further, according to the invention, respective junction allowances of the fabric pieces being adjacent to each other are folded inward and welded in such a condition that the membranes having superior welding property are brought into contact with each other, and thus good welding can be performed. In addition, the junction area is not exposed when worn and thus a good-looking can be obtained.
- Further, according to the invention, respective junction allowances of the fabric pieces being adjacent to each other are extended outward and can be welded in such a condition that the base fabrics are brought into contact with each other.
- Further, according to the invention, respective junction allowances of the fabric pieces being adjacent to each other can be welded in such a condition that one junction allowance is overlaid on the other junction allowance and the base fabric is brought into contact with the membrane.
- Further, according to the invention, rough feeling can be reduced compared with a case the edge portion of one junction area and the edge portion of the other junction area are folded in the same direction when welded to another junction area.
- Further, according to the invention, the thickness of the junction area is the sum of the thicknesses of one fabric and one sealing material only, and thus poor texture due to thicker thickness can be avoided.
- Further, according to the invention, the sealing material is formed of a cloth same as the fabric piece and thus has same functionalities as the fabric piece has. Therefore the portion in which the sealing material is welded can achieve similar functionalities to those achieved by other portions.
- Further, according to the invention, the sealing material is formed of a cloth to which hot-melt is applied. Therefore, the junction area can be readily welded by heating the hot-melt to melt it and cooling it to cure it.
- Further, according to the invention, the leakage of menstrual blood or urine can be surely prevented by welding a crotch line or a crotch portion, since the menstrual blood or urine is likely to leak at these portions.
- Further, according to the invention, the waterproof moisture-permeability of the membrane increases as temperature rises. Therefore, the wetness that tends to occur as temperature rises can be effectively prevented.
- Further, according to the invention, the fabric piece has a higher degree of stretch in horizontal direction, and thus the waterproof moisture-permeable underwear can be easily worn and taken off, and the fit feeling or the mobility when worn can be improved.
- Further, according to the invention (waterproof moisture-permeable liner), almost similar advantages to those of the waterproof moisture-permeable underwear described above can be obtained.

In each drawing, same reference symbols are given for materials or components having a same structure, and duplicate explanation thereof is omitted. In addition, in each drawing, components that are not required for the explanation are omitted as appropriate. In some drawings, directions, up, down, right, and left are shown in arrows. These directions, up, down, right, and left refer to the directions of up, down, right, and left of waterproof moisture-
permeability underwear 10, a waterproof moisture-permeability liner 40, etc. viewed from a wearer. - Although the waterproof moisture-
permeable underwear 10 to which the present invention is applied is called underwear, the description herein is based on the premise that another undergarment for preventing menstrual blood leakage or urine leakage, for example, sanitary shorts or underwear for incontinence, or the like, is worn underneath (inside). In other words, the waterproof moisture-permeable underwear 10 is intended, when the menstrual blood or urine penetrates through and leaks out of the undergarment worn inside theunderwear 10, to prevent staining of the outer garment such as a skirt or trousers worn on (outside) the waterproof moisture-permeable underwear 10 with the menstrual blood or urine. For this reason, it is not required taking into consideration the external appearance of the waterproof moisture-permeable underwear 10 so much, and greater importance is placed on its functionality. - Similar consideration is applied to the waterproof moisture-
permeable liner 40 to which the present invention is applied. - An example in which the waterproof moisture-
permeable underwear 10 is skirt-like underwear 11 is described, with reference toFIG. 1A toFIG. 3D .FIG. 1A is an oblique view of theunderwear 11 viewed from front and obliquely above, andFIG. 1B is an exploded oblique view of theunderwear 11.FIG. 2A is an oblique view illustrating the layer structure and the stretch of a fabric piece (cloth) A, andFIG. 2B illustrates that the moisture-permeability of the fabric piece A varies depending on temperatures.FIG. 3A is an oblique view illustrating an example in which a junction area D1 is formed by folding the junction allowances A1 , A1 at edge portions of two fabric pieces A, A inward and joining them.FIG. 3B is an oblique view illustrating an example in which a junction area D2 is formed by extending the junction allowances A1, A1 outward at edge portions of two fabric pieces A, A outward and joining them.FIG. 3C is an oblique view illustrating that two fabric pieces A, A are welded.FIG. 3D is an oblique view illustrating the junction allowances A1, A1 of two fabric pieces A, A are welded by a seam tape (sealing material) S. - As shown in
FIGS. 1A , 1B, theunderwear 11 is formed in a roughly truncated cone, skirt-like shape by joining two fabric pieces A, A each cut into a predetermined shape, in other words, afront panel 12 and aback panel 13, in ajunction area 11A on the left side and in ajunction area 11B on the right side. - The
front panel 12 is formed into a roughly trapezoid, and long bands ofjunction allowances back panel 13 is also formed similarly into a roughly trapezoid, and long bands ofjunction allowances front panel 12 and theback panel 13 are shaped into the skirt-like underwear 11 by constructing integrally such that thejunction allowance junction area 11A, and thejunction allowance junction area 11B. Under this condition, the upper edge of theunderwear 11 is formed annularly, and, for example, elastic 11 a may be sewn at the upper edge along the periphery in order to prevent theunderwear 11 from slipping down when worn. The lower edge of theunderwear 11 is also formed annularly, anddecorative lace 11 b is provided at the lower edge roughly along the periphery. In the illustrated example, adecorative ribbon 11 c is attached at a front upper edge of theunderwear 11. - Portions other than the elastic 11 a, the
lace 11 b, theribbon 11 c, etc. of the skirt-like underwear 11 constructed as described above are formed of the fabric piece A having waterproof moisture-permeability. The fabric piece A having waterproof moisture-permeability is a fabric that does not allow liquid to pass through, but allows vapor to pass through. As the fabric piece A having such waterproof moisture-permeability, for example, GORE-TEX (Registered trademark) Fabrics manufactured by Japan Gore-Tex Inc., OMNI-TECH manufactured by Columbia Sportswear Company, DRYTEC (registered trademark) manufactured by MontBel Co. Ltd., c_change (registered trademark) from Schoeller, etc are known. - Among these materials, c_change is superior in (1) waterproof moisture-permeability, and (2) by which lightweight can be achieved, and has (3) good texture (soft feeling), (4) stretch, (5) breathability, windproof property, and (6) good welding property. Having such functionalities, c_change can be preferably used as the fabric piece A for making the
underwear 11 of this embodiment, theunderwear 21 of the second embodiment, theunderwear 31 of the third embodiment, theliner 41 of the fourth embodiment, theliner 51 of the fifth embodiment. The description hereinafter is explained on the premise that the fabric piece A is c_change, however, regarding waterproof moisture-permeability, other than c_change, for example, GORE-TEX (Registered trademark) Fabrics or the like may also be used as the fabric piece A, of course. - The fabric piece A is constructed by a base fabric (base) B and a membrane (thin film) C as shown in
FIG. 2A . In other words, the fabric piece A is a two-layered (two layer structure) fabric piece constructed by laminating the membrane C having waterproof moisture-permeability on one surface of the base fabric B. - The fabric piece A contains 30 wt % nylon (base fabric B), and 70 wt % polyurethane (membrane C). By adopting such constituents, the fabric piece A achieves waterproof moisture-permeability. As long as the base fabric B surely supports the membrane C and does not disturb the waterproof moisture-permeability of the membrane C, a synthetic resin other than nylon, or even cotton or the like can also be used as the base fabric B.
- Since the
underwear 11 in this embodiment uses two-layered fabric pieces A, lightweight can be sought compared with those that use general three-layered fabric pieces. A typical example for a garment constructed by a waterproof moisture-permeable material is a raincoat. If the membrane of a raincoat is damaged or peeled, it may allow rain water to enter therefrom. To protect the membrane, therefore, a protecting layer is provided outside the membrane. In addition, a layer for improving the texture (soft feeling), for example, is provided inside the membrane. In other words, a raincoat in general is formed in three layers, and thus the weight tends to be added. There is a two-layered raincoat that does not have an inner layer, however, in this case, a special treatment is provided on the backside of the membrane for improving the texture, and the treatment may increase the cost for creating the fabric. - In contrast, since it is the premise that an outer garment is worn on the
underwear 11, the membrane C can be disposed outer side of the fabric piece A, and the base fabric B can be disposed inner side of the fabric piece A. As such, a two-layered construction can be achieved, and thus lightweight can be more readily achieved than with a three-layered construction. In addition, there is no need to provide a special treatment on the backside of the membrane, and thus the underwear can be constructed at lower cost. - In addition, the
underwear 11 has a wider scope of choices for a material for the base fabric B. Although theunderwear 11 is called underwear, the description herein is based on the premise that undergarment is worn inside. Depending on the size or shape of the undergarment, a portion of the base fabric B that extends over the undergarment may directly contact with the skin of the wearer. Since the base fabric B may contact with the skin as such, a good texture (soft feeling) is required to some extent but not as much as required for the undergarment, and the scope of choices for the material is widened accordingly. As a result, for example, a texture as good as the texture required for the undergarment is not required, and other functionalities can be enhanced (for example, achieving lightweight or improving breathability) accordingly. In this embodiment, a material superior in texture to at least the membrane C is adopted for the base fabric B. More specifically, a synthetic resin other than nylon can be also used for the base fabric B on the condition that the base fabric B is superior to the membrane C in texture. - In addition, the fabric piece A has stretch, and, as shown in
FIG. 2A , for example, the degree of stretch in direction S1 (one direction) is higher than the degree of stretch in the direction S2 (other direction) that is orthogonal to the direction S1. Therefore in a case where the skirt-like underwear 11 as shown inFIG. 1A is formed by the fabric pieces A having such stretch, it is desirable that the direction S1 having a higher degree of stretch be placed horizontally (left-right direction) when thefront panel 12 and theback panel 13 are cut from the fabric piece A. This enables theunderwear 11 to be easily worn and taken off, and the fit feeling or the mobility can be improved when worn. -
FIG. 2B illustrates experimental data on the relation between the temperature of the membrane C and moisture-permeability in a case the fabric piece A is c_change. InFIG. 2B , the horizontal axis shows temperatures (degrees centigrade), and the vertical axis shows moisture-permeability (%). - As temperature rises, the polymer structure of the membrane C opens discretely and thus moisture-permeability is improved. This facilitates to allow moisture to escape to outside, and also facilitates to allow excess heat emitted from the body to escape to outside. In contrast, as temperature lowers, the polymer structure of the membrane C tightly aligns and stores heat, and thus heat retention and comfortable moisture-permeability are maintained.
- More specifically, it is found that, assuming that the moisture-permeability of the membrane C at a temperature of 20 degrees centigrade is 100%, the moisture-permeability at 10 degrees centigrade becomes 50%, as shown in
FIG. 2B . (Source: Empa Test Report No. 841192-2 dated on Dec. 15, 2006). It is also found that the moisture-permeability monotonously increases as temperature rises and monotonously decreases as temperature lowers, in the range between the temperature of 10 degrees centigrade and 20 degrees centigrade. - In addition, the membrane C has breathability but still has windproof property. When wind strikes the membrane C, it bounces off air molecules. However, in a case where the static pressure differs between inside and outside of the membrane C, for example, in a case where when the inner temperature rises and the air pressure that includes partial pressure of vapor becomes higher than the outside air pressure, the air (vapor) can escape from inside to outside.
- (6) Welding Property As described above, the fabric piece A is constructed by the base fabric B and the membrane C, and polyurethane is adopted for the material of the membrane C. Polyurethane has thermoplastic property, and melts when heated and cures when cooled. Therefore, the fabric piece A can be welded well in such a condition that the membranes C, C made of polyurethane are brought into contact with each other, without sewing that uses a string. There are various types of welding, for example, high frequency welding in which the action of high frequency energy causes resin material itself to generate heat from inside, heat welding that heats by the action of thermal conductivity, ultrasonic welding in which ultrasonic energy causes a target material to vibrate and generate a strong frictional heat, and the like. For this embodiment, ultrasonic welding is preferable.
- The junction of two adjacent fabric pieces A, A is described regarding the welding property, with reference to
FIGS. 3A-3D . The welding can be similarly used for a case in which one fabric piece A is looped and then a junction area of one edge portion thereof and a junction area of the other edge portion thereof are joined. Therefore, the case in which two fabric pieces A, A are joined is described below. -
FIGS. 3A and 3B illustrate examples in which two fabric pieces A, A are directly joined, andFIG. 3D illustrates two fabric pieces A, A are joined by using a seam tape (sealing material). - In
FIG. 3A , the edge portion of each of the fabric pieces A, A are folded inward to form bands of junction allowances A1, A1 respectively, and these junction allowances A1, A1 are aligned each other and joined to form a junction area D1. In this case, joining may be done by using a general sewing that uses a string or by the welding shown inFIG. 3C . The welding can be performed by using, for example, an ultrasonic sewing machine. The two fabric pieces A, A are overlaid each other so that their membranes C, C face each other, and the junction areas A1, A1 at their edge portions are inserted between a pair of metal bars M, M. Then, ultrasonic wave is applied to the metal bars M, M. This activates the activities of urethane molecules in polyurethane that makes up the membrane C, and adhesion on the molecular level can be achieved. In the junction area D1 shown inFIG. 3A , the membranes (polyurethane) C, C are welded each other, and thus relatively good welding can be achieved compared with the case the membrane (polyurethane) C and the base fabric (nylon) B are welded, or the base fabrics (nylon) B, B are welded. - In
FIG. 3B , bands of the junction allowances A1, A1 at the edge portion of each of the fabric pieces A, A are extended outward, and these junction areas A1, A1 are aligned each other and joined to form a junction area D2. The junction area D2 in this case may be formed either by a general sewing that uses a string or the welding shown inFIG. 3C . If welding is used, the welding is performed in such a condition that both of the fabric pieces A, A are inside out, inFIG. 3C . In this case, the base fabrics B, B are joined each other. The base fabrics B, B made of nylon have a poorer welding property than the membranes C, C made of polyurethane have, but polyurethane seeps out from the base fabric B, B when welded and achieves the welding. Required waterproofness can be sufficiently obtained even in a case, for example, the base fabrics B, B are welded each other by using an ultrasonic sewing machine as long as the conditions for welding are set as appropriate. - Other than the examples in
FIGS. 3A and 3B , there is another example in which the fabric pieces A, A are directly joined. One example is that one junction allowance Al of one fabric piece A is simply overlaid on the other junction allowance A1 of the other fabric piece A to form a junction area and then the junction area is welded, and such a junction area may also be adopted. This junction area can be adopted when the junction allowances A1, A1 are not curved but linear, and can reduce fabrication cost compared with those inFIGS. 3A and 3B . In this case, the junction area is welded in such a condition that the membrane C of one junction allowance A1 is brought into contact with the base fabric B of the other junction allowance A1. The junction strength of the junction area formed in this manner is smaller than the junction strength of the junction area Dl shown inFIG. 3A but greater than the junction strength shown inFIG. 3B . -
FIG. 3D shows that a junction area D3 is formed by using a seam tape S. End edges A2, A2 of two fabric pieces A, A are aligned each other to form the junction allowances A1, A1, and then a band of the seam tape S is welded on the junction allowances A1, A1. A material similar to the fabric piece A, in other words, the base fabric B and the membrane C laminated thereon, is used for the seam tape S. The base fabrics B, B disposed inner side of the fabric pieces A, A are joined from inside such that with which the membrane C of the seam tape S contacts. This enables the seam tape S to be hidden inside the fabric pieces A, A and not exposed to outside, and thus good-looking can be achieved. In addition, since the base fabrics B, B of the fabric pieces A, A and the membrane C of the seam tape S are joined, the junction strength becomes greater than the junction area D2 inFIG. 3B in which the base fabrics B, B are joined each other. In addition, by using a material similar to the fabric piece A for the seam tape S, superior functionality the fabric piece A has can be achieved similarly also in the junction area D3 that includes the seam tape S. A material different from the fabric piece A can also be used for the seam tape. In this case, for example, a material having no waterproof moisture-permeability but having superior welding property, high degree of stretch, being thin, and having a greater strength or the like can be selected. - For the seam tape S, a seam tape to which hot-melt (adhesive that can be heat welding) is applied can also be used. In this case, two fabric pieces A, A can be joined by heating the hot-melt to melt it and cooling it to cure it.
- The junction strength of the junction welded as described above is now described.
- In terms of junction strength, the junction area D1 in
FIG. 3A is strongest, and the junction area D3 inFIG. 3D is stronger than the junction area D2 inFIG. 3B . This is because the welding property of the membrane C being made of polyurethane is better than the welding property of the base fabric B made of nylon. Specifically, the membranes (polyurethane) C, C are joined in the junction area D1 inFIG. 3A , and the base fabric (nylon) B and the membrane (polyurethane) C are joined in the junction area D3 inFIG. 3D , and the base fabrics (nylon) B, B are joined the junction area D2 inFIG. 3B . - In terms of appearance, it is desirable that the junction area D1 in
FIG. 3A be applied to the underwear 21 (seeFIGS. 4A , 4B), 31(seeFIGS. 6A , 6B), and the junction area D2 inFIG. 3B be used for the liner 41 (seeFIGS. 7A , 7B), 51(seeFIGS. 8A-8C ). Since the junction area D1 inFIG. 3A is folded inward, the area is not seen from outside when used for theunderwear 21, etc. On the other hand, since the junction area D2 inFIG. 3B is extended outward, the area is not seen from either outside or inside when used forliner 41, etc. The junction area D3 inFIG. 3D can be alternatively used instead of the junction areas D1 inFIG. 3A , and D2 inFIG. 3B . - In terms of texture (soft feeling), the junction area D3 in
FIG. 3D is better than the junction areas D1 inFIG. 3A and D2 inFIG. 3B . In other words, the thickness of the junction areas D1, D2 themselves is two times of the thickness of one fabric piece A, but in actual use they are folded on either one of the fabric pieces A and the thickness becomes substantially three times the thickness of one fabric piece A, and thus the rough feeling will be increased. On the other hand, since the junction area D3 inFIG. 3D uses the seam tape S made of a material similar to the fabric piece A, the thickness thereof is almost same as two times of one fabric piece A, and thus the rough feeling can be reduced compared with the three-times thickness. - In the
underwear 11 shown inFIGS. 1A , 1B, the junction area D1 shown inFIG. 3A is adopted for thejunction areas FIGS. 1A , 1B, thejunction areas underwear 11 is located on the left side and the right side of theunderwear 11. Such locations are the portions that are not likely to contact with the menstrual blood or urine that penetrates through undergarment (not shown), for example, compared with a case in which the junction area is located in a front portion or back potion of theunderwear 11. Therefore, in theunderwear 11 shown inFIGS. 1A , 1B, thejunction areas underwear liners - As described above, the skirt-
like underwear 11 as the waterproof moisture-permeable underwear 10 can prevent staining of the outer garment with menstrual blood or urine leaked from the undergarment by using the fabric piece A having waterproof moisture-permeability. In addition, by using the fabric piece A such that the base fabric B is disposed inner side and the membrane C is disposed outer side, two-layered construction being lightweight but having good texture (soft feeling) can be achieved. In addition, if a material having stretch, breathability, and windproof property is used for the fabric piece A, theunderwear 11 can be smoothly worn and taken off, and can achieve a good fit, prevent wind entrance, and reduce wetness inside. In addition, by using a material having a good welding property for the membrane C, the welding of the junction area of the fabric piece A can ensure the waterproofness. - An example in which the waterproof moisture-
permeable underwear 10 is the pants-like underwear 21 is illustrated, with reference toFIGS. 4A , 4B andFIGS. 5A , 5B.FIG. 4A is a view of theunderwear 21 viewed from front and obliquely above.FIG. 4B illustrates theunderwear 21 ofFIG. 4A with a portion thereof being cutaway.FIG. 5A is a view taken along an arrowed line V-V inFIG. 4A .FIG. 5B illustrates the joint condition of a portion at which the lower edge of thejunction area 21A and the lower edge of thejunction area 21B intersect with thejunction areas - The
underwear 21 of this embodiment is intended to be worn relatively (compared withunderwear 31 of a third embodiment described later) loosely (in a loose and ease condition). - As shown in
FIGS. 4A , 4B, theunderwear 21 is constructed by joining four fabric pieces A, A, . . . , each cut into a predetermined shape, in other words, a leftfront panel 22, a rightfront panel 23, aleft back panel 24, and aright back panel 25 in thejunction areas 21A-21F. - The
junction area 21A is located at the front center vertically in which a junction allowance (crotch line) 22 a of the leftfront panel 22 and a junction allowance (crotch line) 23 a of the rightfront panel 23 are joined. Thejunction area 21 B is located at the back center vertically in which a junction allowance (crotch line) 24 a of theleft back panel 24 and a junction allowance (crotch line) 25 a of the right backpanel 25 are joined. Thejunction area 21C is located on the left side vertically in which a junction allowance 22 b of the leftfront panel 22 and ajunction allowance 24 b of theleft back panel 24 are joined. Thejunction area 21D is located on the right side vertically in which ajunction allowance 23 b of the rightfront panel 23 and ajunction allowance 25 b of the right backpanel 25 are joined. Thejunction area 21E is extending from the lower end of thejunction area 21A obliquely left downward in which a junction allowance (crotch portion) 22 c of the leftfront panel 22 and a junction allowance (crotch portion) 24 c of theleft back panel 24 are joined. Thejunction area 21F is extending from the lower end of thejunction area 21A right obliquely downward in which a junction allowance (crotch portion) 23 c of the rightfront panel 23 and ajunction allowance 25 c of the right backpanel 25 are joined. Thejunction area 21E and thejunction area 21F are formed continuously. - By joining as described above, an
upper edge 21 a of the leftfront panel 22, the rightfront panel 23, theleft back panel 24, and the right backpanel 25 of theunderwear 21 is linked annularly, and elastic (not shown) is sewn along the periphery of theupper edge 21 a. This elastic of theunderwear 21 enables a wearer to easily wear and take off it, and prevents slipping down when worn. In addition, alower edge 21 b of the leftfront panel 22 and theleft back panel 24 is linked annularly to form an opening through which the left leg is inserted. Similarly, alower edge 21 c of the rightfront panel 23 and the right backpanel 25 is linked annularly to form an opening through which the right leg is inserted. - For the pants-
like underwear 21 of this embodiment, similar fabric pieces A to the fabric piece A of the first embodiment are used, and is constructed such that the base fabric B is disposed inner side and the membrane C is disposed outer side. - For any of the
junction areas 21A-21F, the junction area D1 shown inFIG. 3A is adopted, and the welding is performed from thejunction area 21A-21F in that order. It is also possible to adopt the junction area D3 shown inFIG. 3D for any of thejunction area 21A-21F and welding is performed. For thejunction areas FIG. 3A can be adopted, and sewing that uses a string can be used instead of welding. - At an intersection at which the junction areas intersect, multiple fabric pieces A are overlaid. Therefore, the intersection becomes thick, which may increase rough feeling. In this embodiment, the increase of the rough feeling is restricted by treating junction areas as described below as shown in
FIG. 5B . When thejunction areas 21A-21 F are welded by adopting the junction area D1 shown inFIG. 3A , four fabric pieces A, A, . . . , in other words, the leftfront panel 22, the rightfront panel 23, theleft back panel 24, and the right backpanel 25, are joined near the lower edges of thejunction area 21A on the front side and thejunction area 21B on the back side in such a condition that one corner of each panel butts against each other, and joined by thejunction areas FIG. 5B . - These
junction areas - At first, the left
front panel 22 and the rightfront panel 23 are joined such thatrespective junction allowances junction area 21A (one junction area). - Then, the
left back panel 24 and the right backpanel 25 are similarly joined such thatrespective junction allowances junction area 21B (the other junction area). - Then, the
junction area 21E (another junction area) and thejunction area 21F (another junction area) are formed continuously. In other words, the leftfront panel 22 and the rightfront panel 23 joined as described above and theleft back panel 24 and the right backpanel 25 similarly joined are joined by weldingjunction allowances junction area 21E, andwelding junction allowances junction area 21F. - In this process, the already formed
junction area 21B is folded to the left (to the left back panel 24), and an edge portion 21Bb of thejunction area 21B is welded to thejunction allowance 24 c in thejunction area 21E. In other words, in appearance, the edge portion 21Bb of thejunction area 21B is joined to thejunction area 21E to constitute a portion thereof. In contrast, the already formedjunction area 21A is folded to the right (to the right front panel 23), and an edge portion 21Aa of thejunction area 21A is welded to thejunction allowance 23 c in thejunction area 21 F. In other words, in appearance, theedge portion 21 Aa of thejunction area 21 A is joined to thejunction area 21F to constitute a portion thereof. - As such, the edge portion 21Aa of the
junction area 21A and the edge portion 21Bb of thejunction allowance 21B are joined in mutually opposite directions. In other words, since the edge portion 21Aa is joined to the right and the edge portion 21Bb is joined to the left, it is prevented that the edge portions 21Aa, 21Bb are joined in a same direction and the thickness at that portion becomes thick, which increases rough feeling. In other words, if the edge portions 21Aa, 21Bb are joined in a same direction, the thickness in that junction area becomes six times of the thickness of one fabric piece A, whereas the thickness in that junction area can be reduced down to four times of the thickness of one fabric piece A by joining theedge portions 21 Aa, 21 Bb in mutually opposite directions, and thus the rough feeling can be reduced. - Although in the description above, the edge portion 21Aa of the
junction area 21A is faced to the right, and the edge portion 21Bb of thejunction area 21B is faced to the left, and then the welding is performed to join them. However, of course, the directions may be vice versa, such that the edge portion 21Aa is faced to the left and the edge portion 21Bb is faced to the right and then welding is performed to join them. In other words, what is required is that the directions of the edge portions 21Aa, 21Bb be opposite each other. - In the pants-
like underwear 21 of this embodiment as the waterproof moisture-permeable underwear 10, almost similar advantages to those of the skirt-like underwear 11 of the first embodiment can be achieved. - An example in which the waterproof moisture-
permeable underwear 10 is pants-like underwear 31 is illustrated, with reference toFIGS. 6A and 6B .FIG. 6A is a view of theunderwear 31 viewed from front and obliquely above, andFIG. 6B is a view taken along an arrowed line B-B inFIG. 6A . Theunderwear 31 of this embodiment is worn with a higher fit than theunderwear 21 of the second embodiment described above. Therefore, the reduction in rough feeling is sought by adopting the junction area D3 shown inFIG. 3D forjunction areas 31A-31D as described later. - As shown in
FIG. 6A , theunderwear 31 is constructed by joining two fabric pieces A, A each cut into a predetermined shape, in other words, a left panel 32 (a front panel and a back panel on the left side formed integrally) and a right panel 33 (a front panel and a back panel on the right side formed integrally) in thejunction areas 31A-31D. - The
junction area 31A is located at the front center vertically in which ajunction allowance 32 a on the front of theleft panel 32 and ajunction allowance 33 a on the front of theright panel 33 are joined. In thejunction area 31B, ajunction allowance 32 b on the back of theleft panel 32 and ajunction allowance 33 b on the back of theright panel 33 are joined. Thejunction area 31A and thejunction area 31B continue at their lower edges. Thejunction area 31C is a junction area of ajunction allowance 32 c at right front lower edge of theleft panel 32 and ajunction allowance 32 d at right back lower edge of theleft panel 32. Thejunction area 31D is a junction area of ajunction allowance 33 c at left front lower edge of theright panel 33 and ajunction allowance 33 d at left back lower edge of theright panel 33. Thejunction area 31C and thejunction area 31D are formed continuously. - By joining as described above, an
upper edge 31 a of theleft panel 32 and theright panel 33 of theunderwear 31 is formed annularly, and elastic (not shown) is sewn along the periphery of theupper edge 31 a. In addition,lower edges left panel 32 and theright panel 33 are sewn inward to form annular openings through which the left leg or the right leg is inserted respectively. - The pants-
like underwear 31 of this embodiment uses similar fabric pieces A to the fabric piece A of the first embodiment, and is constructed such that the base fabric B is disposed inner side and the membrane C is disposed outer side. - Any of the
junction areas 31A-31D is welded by adopting the junction area D3 shown inFIG. 3D . It is also possible to adopt the junction area D1 shown inFIG. 3A for any of thejunction areas 31A-31D. However, if it is taken into account that theunderwear 31 of this embodiment is intended to be worn with a higher fit, it is desirable to adopt the junction area D3 inFIG. 3D , which causes less rough feeling. - In the pants-
like underwear 31 of this embodiment as the waterproof moisture-permeable underwear 10, almost similar advantages to those of the skirt-like underwear 11 of the first embodiment can be achieved. - For the junction areas to be welded in the
underwear FIG. 3A may be preferably adopted. Since the junction areas in theunderwear FIG. 3D may be adopted instead. - An example in which the waterproof moisture-
permeable liner 40 to which the present invention is applied is theliner 41 of theskirt 42 is illustrated, with reference toFIGS. 7A , 7B.FIG. 7A is an oblique view of theskirt 42 viewed from front and obliquely above, andFIG. 7B is an exploded oblique view in which askirt body 43 and theliner 41 are separated. - The
skirt 42 is constructed by theskirt body 43 formed in a roughly truncated cone and acts as an outer fabric, and theliner 41 also formed in a roughly truncated cone and attached inside (behind) theskirt body 43. - The
skirt body 43 has four fabric pieces each cut into a predetermined shape, in other words, an upperfront panel 44, a lowerfront panel 45, anupper back panel 46, and alower back panel 47, and is constructed by joining them injunction areas junction areas 43A-43D is formed by sewing that uses a string. An upper portion of thejunction area 43C on the left side is not joined, and a slit is formed therein. Attached to the slit is azipper 43 a that facilitates an easy take-on and off of theskirt 42. - The
liner 41 is formed by joining two fabric pieces A, A each cut into a predetermined shape, in other words, afront panel 48 and aback panel 49, in ajunction area 41A on the left side and ajunction area 41B on the right side. Thejunction area 41A on the left side is formed by joiningrespective junction allowances front panel 48 and theback panel 49. Thejunction area 41A is not formed in a portion that corresponds to thezipper 43 a at an upper edge portion. Thejunction area 41B on the right side is formed by joiningrespective junction allowances front panel 48 and theback panel 49 from anupper edge 41 a to alower edge 41 b of theliner 41. - The
liner 41 uses similar fabric pieces A to the fabric piece A of the first embodiment, and is constructed such that the base fabric B is disposed inner side and the membrane C is disposed outer side. Then, thejunction areas FIG. 3B . Thesejunction areas skirt 42 and thus the possibility that the menstrual blood or urine leaked out from undergarment worn under theskirt 42 contacts with these portion is quite low. - The
liner 41 is attached inside (behind) theskirt body 43 by sewing the annularupper edge 41 a to thejunction areas skirt body 43, and tyingstrings junction areas skirt body 43. - In this embodiment, the
upper edge 41 a of theliner 41 may be attached to inside theskirt body 43, for example, by using a hook-and-loop fastener, instead of sewing it to theskirt body 43, so that theliner 41 can be easily attached to and detached from theskirt body 43. - In the skirt-
like liner 41 of this embodiment as the waterproof moisture-permeable liner 40, almost similar advantages to those of the skirt-like underwear 11 of the first embodiment can be achieved. - An example in which the waterproof moisture-
permeable liner 40 to which the present invention is applied is theliner 51 of theshort pants 52 is illustrated, with reference toFIGS. 8A-8C .FIG. 8A is an oblique view of theshort pants 52 viewed from front and obliquely above.FIG. 8B is an oblique view of aliner 51 viewed from front and obliquely above.FIG. 8C is an oblique view of ashort pants body 53 viewed from front and obliquely above. - The short pants
body 53 has an annular opening at anupper edge 53 a through which the wearer torso is inserted, and also has openings at each oflower edges zipper 53 d that facilitates an easy take-on and off is attached to the slit. Regarding the shape or structure of theshort pants body 53, ones similar to those used for general short pants can be used, and thus detailed description on theshort pants body 53 is omitted. - The
liner 51 is constructed by joining four fabric pieces A, A, . . . , each cut into a predetermined shape, in other words, a leftfront panel 54, a rightfront panel 55, aleft back panel 56, and aright back panel 57 injunction areas 51A-51D. Thejunction area 51A on the front is formed by joining ajunction allowance 54 a on the right side of the leftfront panel 54 and ajunction allowance 55 a on the left side of the rightfront panel 55. At an upper portion of thejunction area 51A that corresponds to thezipper 53d of theshort pants body 53, the leftfront panel 54 and the rightfront panel 55 are not joined and overlaid each other, and sewn to inside (behind) theshort pants body 53. Thejunction area 51B on the back side is formed by joining ajunction allowance 56 a on the right side of theleft back panel 56 and ajunction allowance 57 a on the left side of the right backpanel 57. Thejunction area 51C on the left side is formed by joining ajunction area 54 b on the left side of the leftfront panel 54 and ajunction allowance 56 b on the left side of theleft back panel 56. Then, thejunction area 51D on the right side is formed by joining ajunction area 55 b on the right side of the rightfront panel 55 and a junction allowance 57 b on the right side of the right backpanel 57. By joining as described above, an annular opening through which the wearer torso is inserted is formed at an upper edge 51 a of theliner 51, and openings through which the leg is inserted is formed at alower edge 51 bon the left and at alower edge 51 c on the right, respectively. - The
liner 51 uses similar fabric pieces A to the fabric piece A of the first embodiment, and is constructed such that the base fabric B is disposed inner side and the membrane C is disposed outer side. For thejunction areas 51A-51D, the junction area D2 shown inFIG. 3B is adopted and the welding is performed. Among thesejunction areas 51A-51D, thejunction area 51C on the left and thejunction area 51D on the right are located on the left side and the right side of theshort pants 52 and the possibility that the menstrual blood or urine leaked out from undergarment worn inside of theshort pants 52 contacts with these portions is quite low, and thus may be joined by sewing that uses a string. - The
liner 51 is attached to theshort pants body 53 by sewing the annular upper edge 51 a to a portion slightly lower than theupper edge 53 a in an inner side of (behind) theshort pants body 53, and by tyingstrings junction area 51C on the left side and thejunction area 51D on the right side to respective fastening loops (not shown) correspondingly provided inside theshort pants body 53. - In the short pants-like
liner 51 of this embodiment as the waterproof moisture-permeable liner 40, almost similar advantages to those of the skirt-like underwear 11 of the first embodiment can be achieved. - The
liner 51 described above can be used as a liner of boxer shorts or training wear, for example, made of nylon, to be worn during exercise. Theliner 51 has waterproof moisture-permeability, and is lightweight, and has good texture, stretch, breathability, and windproof property. It is therefore quite desirable to be used for a liner for boxer shorts or the like, in which moisture tends to gather because body temperature rises due to exercise. On the surface of the boxer shorts or training wear, any desired colored patterns or characters can be printed readily compared with the fabric piece A. Therefore, boxer shorts or training wear being fashionable and having superior functionalities can be constructed. It is intended that the wearers of boxer shorts or training pants to do strenuous exercise, and thus it is desirable that theliner 51 to be attached inside thereof adopt the junction area D1 shown inFIG. 3A that has a greater junction strength. However, in this case, the junction area D1 is formed inside of theliner 51, in other words, the side seen by others, and is a little inferior in appearance. - Regarding the junction area to be welded in the
liners FIG. 3B is adopted, and the junction area is located outside of the liner and covered by the outer garment and is not exposed to outside (inner side) and thus has good-looking. However, if greater importance is placed on the junction strength, it is desirable to adopt the junction area D1 shown inFIG. 3A that provides a little poor appearance but greater junction strength. Examples of such occasions are boxer shorts or training wear described above. - When junction areas are formed by welding in the waterproof moisture-
permeable underwear 10 and the waterproof moisture-permeable liner 40 according to the present invention described above, any of welding described above can be adopted under a condition that required junction strength can be obtained. Which welding is to be adopted may be determined considering other conditions, for example, appearance, ease of processing or the like. - Description of references in drawings
