[0017] Hereinafter, an embodiment of a pants-type wearing article will be described with reference to the drawings.

[0018] (First embodiment)

[0019] Fig. 1 shows a pants-type wearing article 1 of a first embodiment in an unfolded state. The pants-type wearing article 1 is assumed to be men's pants. Fig. 1 shows the inner surface of the pants-type wearing article 1 that faces the skin of a wearer.

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

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

[0022] FIG. 4 is a cross-sectional view taken along line AA in FIG.

[0023] The pants-type wearing article 1 is composed of a pants 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 pants body 40 is made up of a front body section 10, a back body section 20, and a crotch section 30. The front body section 10 constitutes the front side of the pants body 40. The back body section 20 constitutes the back side of the pants body 40.

[0025] The crotch section 30 constitutes the portion disposed between the front section 10 and the back section 20.

[0026] The pants body 40 is made up of a fabric body 41. The fabric body 41 is made up of natural fibers such as cotton and linen, and chemical fibers such as rayon, acetate, acrylic, polyester, and polyurethane.

[0027] The pant body 40 may be manufactured by sewing the front body 10, back body 20, and crotch body 30 together as separate pieces of fabric, or by manufacturing any two of the front body 10, back body 20, and crotch body 30 as separate pieces of fabric, or by manufacturing the pant body 40 by manufacturing all of the front body 10, back body 20, and crotch body 30 as a single piece of fabric.

[0028] For example, silver ions (Ag+) can be used as the antibacterial metal particles 42. The silver ions (Ag+) 42 are added throughout the fabric body 41. The silver ions (Ag+) 42 are attached to the fiber surface by, for example, impregnating the fibers of the fabric body 41.

[0029] When a fabric body 41 made of natural or synthetic fibers is immersed in a silver ion solution, nano-silver particles are attached to the surface of the fibers. Silver has metallic properties that allow it to maintain a zeta potential (surface charge of the particles) in the form of nanoparticles. When silver ions (Ag+) and positively charged silver nanoparticles are adsorbed onto the surface of negatively charged odorous substances, the molecules of the odorous substances are oxidized and decomposed, eliminating them.

[0030] The silver ions (Ag+) 42 added throughout the entire fabric body 41 in this manner inhibit body odor and fart odor inside the pants body 40 from being released 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 the silver ions (Ag+) 42 into the fibers at the stage of spinning the fibers may be used.

[0032] The antibacterial metal particles 42 may also be made of copper ions (Cu+), for example.

[0033] A first activated carbon layer 1C is disposed in a first odor release suppression region 41A, which is a partial region on the skin side of the fabric main body 41. The first activated carbon layer 1C is made of carbon fiber formed into a sheet shape.

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

[0035] The first skin side fabric 51 sandwiches the first activated carbon layer 1C and is joined to the fabric main body 41 by, for example, sewing. Note that any joining method, such as heat fusion, can be used. The same applies below.

[0036] First activated carbon layer 1C adsorbs odorous substances through the micropores of the carbon fiber, thereby suppressing the release of odors from sweat, urine, and other excrement in first odor release suppression region 41A to the outside.

[0037] A second activated carbon layer 2C is disposed in the fart odor emission suppression region 51A, which is a portion of the skin-side region 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 from carbon fiber in a sheet shape, similar to the first activated carbon layer 1C.

[0038] The flatus odor emission suppression region 51A, which is a partial region 51A on the skin side of the first skin side fabric 51, is made up of a partial region 32A of the first crotch region 31A and a partial region 22A of the first back region 21A.

[0039] Fart odor emission suppression area 51A is an area for suppressing the emission of fart odor generated from the anus to the outside.

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

[0041] The second activated carbon layer 2C adsorbs odorous substances through the micropores of the carbon fiber, thereby suppressing the release of sweat, urine, and other excrement odors, particularly the odor of farts, in the fart odor release suppression region 51A to the outside.

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

[0043] (Effective in suppressing the release of fart odor to the outside)

[0044] When a wearer of the pants-type wearing article 1 inadvertently releases a fart from the anus, the fart odor is captured by the second activated carbon layer 2C in the fart odor emission suppression region 51A, which is the region that spreads around the anus. Furthermore, because the first activated carbon layer 1C is provided in the thickness direction of the second activated carbon layer 2C, the fart odor that travels in the thickness direction and that the second activated carbon layer 2C was unable to capture is captured by the first activated carbon layer 1C. Furthermore, because the fabric main body 41 to which silver ions (Ag+) 42 are added is provided in the thickness direction of the first activated carbon layer 1C, the fart odor that travels in the thickness direction and that the second activated carbon layer 2C and the first activated carbon layer 1C were unable to capture is captured by the fabric main body 41.

[0045] In addition, since the first activated carbon layer 1C is extended outward from the second activated carbon layer 2C in the fart odor emission suppression region 51A, the outward spreading fart odor that was not captured by the second activated carbon layer 2C is captured by the first activated carbon layer 1C. Furthermore, since the fabric main body 41 to which silver ions (Ag+) 42 have been added is extended outward from the first odor emission suppression region 41A, the outward spreading fart odor that was not captured by the second activated carbon layer 2C and the first activated carbon layer 1C is captured by the fabric main body 41.

[0046] Therefore, according to the first embodiment, compared to the prior art, it is possible to prevent the odor of farts from being released to the outside.

[0047] (Fabric and carbon fiber material reduction effect)

[0048] According to the first embodiment, the areas of the first skin-side fabric 51 (first odor release suppression region 41A) and the first activated carbon layer 1C can be made smaller than the area of ​​the fabric main body 41. Furthermore, the areas of the second skin-side fabric 52 (fart odor release suppression region 51A) and the second activated carbon layer 2C can be made smaller than the first skin-side fabric 51 (first odor release suppression region 41A) and the first activated carbon layer 1C. This allows the amount of fabric and carbon fiber material used and costs to be minimized while still achieving the effect of suppressing the external release of fart odor.

[0049] (Improves comfort and appearance of the lower body)

[0050] According to the first embodiment, when a wearer wears the pants-type wearing article 1, the waist portion and the side portions of the buttocks are only thickened by the main fabric body 41, without the additional thickness of the first skin-side fabric 51 and the second skin-side fabric 52. This provides the effect of suppressing the release of flatulence odor to the outside, while providing a comfortable fit, making the underwear lines at the waist portion and the side portions of the buttocks less noticeable, and improving the appearance of the wearer's lower body.

[0051] (Second embodiment)

[0052] 5 shows a pants-type wearing article 2 of the second embodiment in an unfolded state. The pants-type wearing article 2 is intended to be women's pants. FIG. 5 shows the inner surface of the pants-type wearing article 2 that faces the skin of a wearer.

[0053] FIG. 6 is a front view of the pants-type wearing article 2 as seen from the front side.

[0054] FIG. 7 is a rear view of the pants-type wearing article 2 as seen from the rear side.

[0055] FIG. 8 is a cross-sectional view taken along line AA in FIG.

[0056] Hereinafter, components that overlap with those in the first embodiment will be given the same reference numerals and redundant explanations will be omitted as appropriate. Differences from the first embodiment will be described below.

[0057] The pants-type wearing article 2 is composed of a pants body 40, antibacterial metal particles 42, a first activated carbon layer 1C, a first skin-side fabric 51, a third activated carbon layer 3C, and a third skin-side fabric 53.

[0058] A third activated carbon layer 3C is disposed in the menstrual odor release suppression region 51B, which is a portion of the skin-side region 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 from carbon fiber in a sheet shape, similar to the first activated carbon layer 1C.

[0059] The menstrual odor release suppression region 51B, which is a partial region 51B on the skin side of the first skin side fabric 51, is made up of a partial region 32B of the first crotch region 31A and a partial region 12A of the first front region 11A.

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

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

[0062] The third activated carbon layer 3C adsorbs odorous substances through the micropores of the carbon fiber, thereby suppressing the release of sweat, urine, and other excrement odors, especially menstrual odor, from the menstrual odor release suppression region 51B to the outside.

[0063] The pants-type wearing article 2 of the second embodiment can prevent menstrual odor from being released to the outside, as described in the first embodiment. It also has the effect of reducing the amount of fabric and carbon fiber material used. It also has the effect of improving the wearing comfort and the appearance of the lower body.

[0064] (Third embodiment)

[0065] 9 shows a pants-type wearing article 3 of the third embodiment in an unfolded state. The pants-type wearing article 3 is intended to be women's pants. FIG. 9 shows the inner surface of the pants-type wearing article 3 that faces the skin of a wearer.

[0067] FIG. 11 is a rear view of the pants-type wearing article 3 as seen from the rear side.

[0068] FIG. 12 is a cross-sectional view taken along line AA in FIG.

[0069] Hereinafter, components that overlap with those in the first and second embodiments will be given the same reference numerals and redundant explanations will be omitted as appropriate. Differences from the first and second embodiments will be described below.

[0070] The third embodiment is configured by combining the components of the first and second embodiments.

[0071] The pants-type wearing article 3 is composed of a pants body 40, antibacterial metal particles 42, a first activated carbon layer 1C, a first skin-side fabric 51, a second activated carbon layer 2C, a third activated carbon layer 3C, a second skin-side fabric 52, and a third skin-side fabric 53.

[0072] The second activated carbon layer 2C and the third activated carbon layer 3C may be integral or separate. Alternatively, the second activated carbon layer 2C and the third activated carbon layer 3C may be separate and partially overlapped.

[0073] The second skin side fabric 52 and the third skin side fabric 53 may be integral or separate. Also, the second skin side fabric 52 and the third skin side fabric 53 may be separate fabrics that are partially overlapped.
