Benefits of technology

[0034]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.
[0035]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.
[0036]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.
[0037]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.
[0038]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.
[0039]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.

Problems solved by technology

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.

first embodiment

[0060]An example in which the waterproof moisture-permeable underwear 10 is skirt-like underwear 11 is described, with reference to FIG. 1A to FIG. 3D. FIG. 1A is an oblique view of the underwear 11 viewed from front and obliquely above, and FIG. 1B is an exploded oblique view of the underwear 11. FIG. 2A is an oblique view illustrating the layer structure and the stretch of a fabric piece (cloth) A, and FIG. 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 ...

second embodiment

[0088]An example in which the waterproof moisture-permeable underwear 10 is the pants-like underwear 21 is illustrated, with reference to FIGS. 4A, 4B and FIGS. 5A, 5B. FIG. 4A is a view of the underwear 21 viewed from front and obliquely above. FIG. 4B illustrates the underwear 21 of FIG. 4A with a portion thereof being cutaway. FIG. 5A is a view taken along an arrowed line V-V in FIG. 4A. FIG. 5B illustrates the joint condition of a portion at which the lower edge of the junction area 21A and the lower edge of the junction area 21B intersect with the junction areas 21E, 21F, viewed from inside.

[0089]The underwear 21 of this embodiment is intended to be worn relatively (compared with underwear 31 of a third embodiment described later) loosely (in a loose and ease condition).

[0090]As shown in FIGS. 4A, 4B, the underwear 21 is constructed by joining four fabric pieces A, A, . . . , each cut into a predetermined shape, in other words, a left front panel 22, a right front panel 23, a l...

third embodiment

[0104]An example in which the waterproof moisture-permeable underwear 10 is pants-like underwear 31 is illustrated, with reference to FIGS. 6A and 6B. FIG. 6A is a view of the underwear 31 viewed from front and obliquely above, and 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 D3 shown in FIG. 3D for junction areas 31A-31D as described later.

[0105]As shown in FIG. 6A, 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 31A-31D.

[0106]The junction area 31A is located at the front center vertically in which ...

Abstract

Disclosed is a waterproof moisture-permeable underwear by which the scope of choices for a material can be widened, and the waterproofness in junction areas can be improved so that staining of an outer garment with urine or menstrual blood leaked from undergarment can be surely prevented. A waterproof moisture-permeable underwear to be worn between undergarment and the outer garment worn on the lower body is constructed by joining a plurality of two-layered fabric pieces (A), each comprising a base fabric (B) disposed facing the undergarment and a waterproof moisture-permeable membrane (C) laminated on a surface of the base fabric (B) facing the outer garment, in junction areas; wherein a material superior to the membrane (C) in texture is selected for the base fabric (B); a material superior to the base fabric (B) in welding property is selected for the membrane (C); and the junction areas (21A-21F) are formed by welding.

Description

TECHNICAL FIELD[0001]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.BACKGROUND[0002]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.[0003]To eliminate such uncomfortable feeing, for example, sanitary shorts using a fabric having waterproof permeability is proposed in Patent document 1.[0004]In the disclosure, the “gusset” located in the crotch portion of the shorts is constr...
