Mode for Carrying Out the Invention

[0017] Hereinafter, embodiments of the pant-type wearing article will be described with reference to the drawings.

[0018] (First Embodiment)

[0019] Figure 1 shows the unfolded state of the pant-type wearing article 1 according to the first embodiment. The pant-type wearing article 1 is assumed to be men's pants. Figure 1 shows the inner surface on the skin side of the wearer of the pant-type wearing article 1.

[0020] Figure 2 is a front view of the pant-type wearing article 1 as seen from the front side.

[0021] Figure 3 is a rear view of the pant-type wearing article 1 as seen from the rear side.

[0022] Figure 4 is a cross-sectional view taken along line A-A of FIG. 1.

[0023] The pant-type wearing article 1 includes a pant body 40, antibacterial metal particles 42, a first activated carbon layer 1C, a first skin-side fabric 51, a second activated carbon layer 2C, and a second skin-side fabric 52.

[0024] The pant body 40 consists of a front body portion 10, a rear body portion 20, and a crotch portion 30. The front body portion 10 constitutes the front side of the pant body 40. The rear body portion 20 constitutes the rear side of the pant body 40.

[0025] The crotch portion 30 constitutes a portion disposed between the front body portion 10 and the rear body portion 20.

[0026] The pant body 40 is constituted by a fabric body 41. The fabric body 41 is constituted using natural fibers such as cotton and hemp, and chemical fibers such as rayon, acetate, acrylic, polyester, and polyurethane as materials.

[0027] Note that the pant body 40 may be manufactured by sewing the front body portion 10, the rear body portion 20, and the crotch portion 30 with separate fabrics, or the pant body 40 may be manufactured by making any two of the front body portion 10, the rear body portion 20, and the crotch portion 30 with separate fabrics, or the pant body 40 may be manufactured by making the front body portion 10, the rear body portion 20, and the crotch portion 30 all with an integral fabric.

[0028] As the antibacterial metal particles 42, for example, silver ions (Ag+) can be used. The silver ions (Ag+) 42 are added over the entire fabric body 41. The silver ions (Ag+) 42 are adhered to the fiber surface, for example, by being impregnated in the fibers of the fabric body 41.

[0029] When a silver ion solution is immersed in a fabric body 41 made of natural fibers or chemical fibers, nano silver particles adhere to the fiber surface. Silver has the metallic property of retaining the zeta potential (the surface charge of fine particles) in the state of nano fine particles. By adsorbing positively charged silver nanoparticles onto the surface of silver ions (Ag+) and negatively charged odor substances, the molecules of the odor substances can be oxidized and decomposed to be killed.

[0030] In this way, the silver ions (Ag+) 42 added throughout the fabric body 41 suppress the release of body odor and flatulence odor inside the pants body 40 to the outside.

[0031] As a method for adding silver ions (Ag+) 42 to the fibers of the fabric body 41, a method of kneading them into the interior of the fibers at the stage of spinning the fibers may be used.

[0032] As the antibacterial metal particles 42, for example, it is also possible to use copper ions (Cu+).

[0033] A first activated carbon layer 1C is disposed in a first odor release suppression region 41A which is a part of the region on the skin side of the fabric body 41. The first activated carbon layer 1C is formed by shaping carbon fibers into a sheet.

[0034] The first odor release suppression region 41A which is a part of the region 41A on the skin side of the fabric body 41 consists of a first crotch region 31A of the crotch portion 30, a first front body region 11A on the first crotch region 31A side of the front body portion 10, and a first rear body region 21A on the first crotch region 31A side of the rear body portion 20.

[0035] The first skin-side fabric 51 is joined to the fabric body 41 by, for example, sewing, with the first activated carbon layer 1C sandwiched therebetween. As the joining method, any method such as heat fusion can be used. The same applies hereinafter.

[0036] The first activated carbon layer 1C adsorbs odor substances in the micropores of the carbon fiber. Therefore, the first activated carbon layer 1C suppresses the release of odors from sweat, urine, and other excreta in the first odor release suppression region 41A to the outside.

[0037] A second activated carbon layer 2C is disposed in the feces odor release suppression region 51A, which is a part of the skin side of the first skin-side fabric 51. The second activated carbon layer 2C is configured to have a smaller area than the first activated carbon layer 1C. The second activated carbon layer 2C is formed by shaping carbon fiber into a sheet, similar to the first activated carbon layer 1C.

[0038] The feces odor release suppression region 51A, which is a part of the skin side of the first skin-side fabric 51, consists of a part of the region 32A in the first crotch region 31A and a part of the region 22A in the first back region 21A.

[0039] The feces odor release suppression region 51A is a region for suppressing the release of feces odor generated from the anus to the outside.

[0040] The second skin-side fabric 52 sandwiches the second activated carbon layer 2C and is joined to the first skin-side fabric 51, for example, by sewing.

[0041] The second activated carbon layer 2C adsorbs odor substances in the micropores of the carbon fiber. Therefore, the second activated carbon layer 2C suppresses the release of odors from sweat, urine, and other excreta, particularly feces odor, in the feces odor release suppression region 51A to the outside.

[0042] (Effects of the pant-type wearing article 1 of the first embodiment)

[0043] (Effect of suppressing external release of feces odor)

[0044] If the wearer of the pant-type wearing article 1 inadvertently farts and releases it from the anus, the odor of the fart is captured by the second activated carbon layer 2C of the fart odor release suppression region 51A, which is an area that spreads around the anus. Furthermore, since the first activated carbon layer 1C is provided in the thickness direction of the second activated carbon layer 2C, the odor of the fart that cannot be completely captured by the second activated carbon layer 2C in the thickness direction is captured by the first activated carbon layer 1C. Furthermore, since the fabric body 41 with silver ions (Ag+) 42 added is provided in the thickness direction of the first activated carbon layer 1C, the odor of the fart that cannot be completely captured by the second activated carbon layer 2C and the first activated carbon layer 1C in the thickness direction is captured by the fabric body 41.

[0045] Also, since the first activated carbon layer 1C extends outward of the second activated carbon layer 2C in the fart odor release suppression region 51A, the odor of the fart that spreads outward and cannot be completely captured by the second activated carbon layer 2C is captured by the first activated carbon layer 1C. Furthermore, since the fabric body 41 with silver ions (Ag+) 42 added extends outside the first odor release suppression region 41A, the odor of the fart that spreads outward and cannot be completely captured by the second activated carbon layer 2C and the first activated carbon layer 1C is captured by the fabric body 41.

[0046] Therefore, according to the first embodiment, compared with the prior art, it is possible to prevent the release of fart odor to the outside.

[0047] (Effect of reducing fabric and carbon fiber material)

[0048] According to the first embodiment, the areas of the first skin-side fabric 51 (the first odor release suppression region 41A) and the first activated carbon layer 1C can be made smaller than the area of the fabric body 41. Furthermore, the areas of the second skin-side fabric 52 (the fart odor release suppression region 51A) and the second activated carbon layer 2C can be made smaller than the areas of the first skin-side fabric 51 (the first odor release suppression region 41A) and the first activated carbon layer 1C. Therefore, while minimizing the usage amounts of the fabric and carbon fiber materials and the cost, an effect of suppressing the external release of fart odor can be obtained.

[0049] (Effect of improving wearing comfort and the appearance of the lower body)

[0050] According to the first embodiment, when the wearer wears the pant-type wearing article 1, the waist portion and the side portions of the buttocks do not have the thickness of the first skin-side fabric 51 and the second skin-side fabric 52 added only by the thickness of the fabric body 41. Therefore, while obtaining the effect of suppressing the external release of body odor, the wearing feeling is good, the line of the underwear at the waist portion and the side portions of the buttocks is less conspicuous, and the effect that the appearance of the lower body of the wearer looks good is obtained.

[0051] (Second Embodiment)

[0052] FIG. 5 shows the unfolded state of the pant-type wearing article 2 of the second embodiment. The pant-type wearing article 2 is assumed to be women's pants. FIG. 5 shows the inner surface on the skin side of the wearer of the pant-type wearing article 2.

[0058] A third activated carbon layer 3C is disposed in a physiological odor release suppression region 51B which is a part of the region on the skin side of the first skin-side fabric 51. The third activated carbon layer 3C is configured to have a smaller area than the first activated carbon layer 1C. The third activated carbon layer 3C is formed by forming carbon fibers in a sheet shape in the same manner as the first activated carbon layer 1C.

[0059] The body odor release suppression region 51B, which is a part of the body side surface of the first body side fabric 51, consists of a part of the region 32B in the first crotch region 31A and a part of the region 12A in the first front body region 11A.

[0060] The body odor release suppression region 51B is a region for suppressing the external release of body odor generated from the vagina.

[0061] The third body side fabric 53 is joined to the first body side fabric 51, for example, by sewing, with the third activated carbon layer 3C sandwiched therebetween.

[0062] The third activated carbon layer 3C adsorbs odor substances in the micropores of carbon fibers.
