[0050] As shown in FIG. 2, in the first embodiment of the present application, the absorbent garment may include a pants body 10, a base layer 20, and an absorption layer 30.
[0051] As shown in FIG. 1, the pants body 10 has an upper edge 11 for surrounding a wearer's waist during wearing, two leg openings 12 and 13 configured to allow the wearer's legs to pass through, and a crotch region 14 located between the two leg openings 12 and 13.
[0052] The pants body 10 is made, at least in the crotch region 14, from a functional fabric that is breathable and moisture-wicking, such as Modal, Lycra, or cotton material with a honeycomb weave, to further enhance overall comfort.
[0053] As shown in FIGS. 1, 2, and 3, the base layer 20 is combined with the pants body 10 at least on both sides of the crotch region 14. The base layer 20 and the pants body 10 enclose a receiving space 40, and the base layer 20 is configured to face toward the wearer's crotch during wearing. In one embodiment, the base layer 20 is combined with the pants body 10 at least on the left and right sides of the crotch region 14. The both sides of the crotch region 14 refer to the left and right sides respectively near the left and right leg openings 12 and 13.
[0054] As shown in FIG. 3, the pants body 10 has a first edge 15 on one side of the crotch region 14, and the base layer 20 has a second edge 21 corresponding to the first edge 15. The first edge 15 and the second edge 21 extend into the receiving space 40 and are sewn together by stitching 41 within the receiving space 40. The one side edge of the crotch region 14 refers to either the left or right side. In this embodiment, both sides of the crotch region 14 are sewn using the same method described above. It should be understood that, in some embodiments, only one side may employ the aforementioned stitching method, while the other side may use a different stitching method or an adhesive bonding method, which is not limited in the embodiments of the present application.
[0055] As shown in FIG. 3, the absorption layer 30 is located within the receiving space 40 and combined with the base layer 20. The absorption layer 30 may be composed of one or more materials selected from terry cloth, dust-free paper, fluff pulp, superabsorbent polymer (SAP), and hydrophilic non-woven fabric. In some embodiments, the absorption layer 30 may also be combined with the pants body 10. For details, refer to the description of the embodiments below.
[0056] As shown in FIG. 3, in one embodiment, the first edge 15 of the pants body 10 is folded and extends into the receiving space 40. This ensures a smooth outer surface at the joint of the pants body, preventing discomfort in the crotch region.
[0057] As shown in FIG. 3, in one embodiment, the stitching 41 is concealed within the receiving space 40. By sewing the first edge 15 of the pants body 10 and the second edge 21 of the base layer 20 together within the receiving space 40, the stitching 41 is fully contained and hidden inside this space. This internal enclosed stitching structure provides multiple benefits: First, it ensures the stitching is completely isolated from the wearer's skin, fundamentally eliminating any potential friction from the stitches and thereby enhancing skin-contact comfort. Second, compared to large-area adhesive bonding, the stitching itself does not form a sealed barrier, preserving breathable pathways in this area. This allows for faster drying after washing and improves the feeling of dryness during wear. Finally, the connection method via stitching offers far superior mechanical strength and washing durability compared to adhesive bonding, effectively overcoming the issue of adhesive failure.
[0058] As shown in FIGS. 1, 2, and 3, in one embodiment, the base layer 20 includes a first region 22 and a second region 23. The first region 22 is located at a middle position of the crotch region 14, while the second region 23 is located at side positions of the crotch region 14. A liquid absorption rate per unit area of the first region 22 is greater than that of the second region 23. In this manner, due to the liquid wicking effect, liquid is concentrated in the first region 22 at the middle position of the crotch region 14, where it is absorbed and directed to the absorption layer 30, thereby reducing the risk of side leakage. In one embodiment, the coverage area of the first region 22 accounts for more than 90% of the total coverage area of the base layer 20, while the coverage area of the second region 23 accounts for less than 10% of the total coverage area of the base layer 20. There may be two second regions 23, which may be located on the left and right sides of the first region 22, respectively.
[0059] As shown in FIGS. 1, 2, and 3, in one embodiment, the first region 22 is configured to allow penetration therethrough and flow toward the absorption layer 30. The second region 23 at least partially uses a waterproof material and is configured to prevent lateral diffusion of liquid and prevent penetration of liquid to the absorption layer 30. The base layer 20 adopts a zoned design, with its core functions being directional liquid guidance and three-dimensional leakage prevention. The centrally located first region 22 serves as a guiding zone. It employs a unidirectional moisture-wicking fabric 22, which can quickly wick liquids such as menstrual fluid from the skin surface and direct them to the underlying absorption layer 30. Meanwhile, leveraging its unidirectional moisture-wicking property, it effectively reduces liquid backflow, maintaining relative dryness on the skin-contact surface.
[0060] As shown in FIGS. 1, 2, and 3, in one embodiment, the first region 22 is a unidirectional moisture-wicking fabric 22, configured to allow liquid to penetrate unidirectionally from the wearer's body to the absorption layer 30. In a specific example, the unidirectional moisture-wicking fabric 22 is a lightweight knitted fabric with a basis weight ranging from 95 g/m.sup.2 to 110 g/m.sup.2. Optionally, the unidirectional moisture-wicking fabric 22 has a rib-jacquard structure formed from hydrophobic polymer yarns (e.g., polyester), utilizing its specific knit construction to generate a capillary effect, thereby achieving the unidirectional moisture-wicking function. It should be understood that the unidirectional moisture-wicking fabric 22 is not limited to the aforementioned specific composition. It can be any functional fabric capable of achieving unidirectional liquid transport via capillary action, differential wettability, or a combination thereof. For example, the unidirectional moisture-wicking fabric 22 may be a double-layer composite structure, with its skin-facing layer comprising hydrophobic fibers such as fine-denier polyester or polypropylene, and its body-facing layer comprising hydrophilic fibers such as cotton or rayon. Alternatively, the unidirectional moisture-wicking fabric 22 may also be obtained by applying differential hydrophilic/hydrophobic finishing treatments to the inner and outer surfaces of a single-layer fabric.
[0061] As shown in FIG. 4, the second region 23 comprises a hydrophobic base layer 232 and a waterproof adhesive layer 233 arranged in a laminated configuration, with the hydrophobic base layer 232 being closer to the wearer's skin than the waterproof adhesive layer 233. The second regions 23 located on the sides constitute leakage prevention zones. Their laminated structure (the hydrophobic base layer 232 and the waterproof adhesive layer 233) works in synergy: the hydrophobic base layer 232, which is closer to the skin, effectively prevents liquid from spreading over its surface, forcing the liquid to concentrate toward the central guiding zone; while the waterproof adhesive layer 233 acts as a further barrier, preventing any potential penetrated liquid from wetting the pants body 10. This mechanism of zoned, coordinated operation significantly enhances the reliability of side leakage prevention while ensuring efficient absorption. The hydrophobic base layer 232 is a non-woven or woven fabric possessing hydrophobic properties. The waterproof adhesive layer 233 is a continuous waterproof barrier layer, its material selected from thermoplastic polyurethane (TPU) film, polyethylene (PE) film, or waterproof polyurethane (PU) coating. This layer is combined with the hydrophobic base layer 232 via a thermal lamination process, forming a barrier that, due to its dense and pore-free microstructure, completely blocks liquid penetration to the pants body 10.
[0062] As shown in FIGS. 1-3, in one embodiment, the first region 22 is a first portion 22 of the base layer 20, and the second region 23 is a second portion 23 of the base layer 20. The first portion 22 has a third edge 221, and the second portion 23 has a fourth edge 231 adjacent to the third edge 221. The third edge 221 and the fourth edge 231 extend into the receiving space 40 and are combined within the receiving space 40. In other embodiments, the base layer 20 may be a single, integral piece. For details, refer to the description of a second embodiment below.
[0063] As shown in FIG. 3, in one embodiment, the fourth edge 231 of the second portion 23 is folded and extends into the receiving space 40. This ensures a smooth outer surface at the joint of the pants body, preventing discomfort in the crotch region.
[0064] As shown in FIG. 3, in one embodiment, the third edge 221 and the fourth edge 231 are sewn together by stitching 42. In some other embodiments, the third edge 221 and the fourth edge 231 may also be bonded by an adhesive.
[0065] In one embodiment, the absorbent garment further comprises a pants body waterproof layer 50 disposed on at least a portion of a surface of the pants body 10 facing the receiving space 40. Optionally, the pants body waterproof layer 50 covers the entire inner surface of the crotch region 14.
[0066] In one embodiment, a width of the absorption layer 30 is smaller than a width of the crotch region 14, and edges of the absorption layer 30 do not extend to edges of the crotch region 14. In this manner, since the absorption layer 30 does not extend to the edges of the crotch region 14, the risk of side leakage can be reduced.
[0067] In one embodiment, the absorption layer 30 and the first portion 22 are jointly combined with the second portion 23. The absorption layer 30 has a fifth edge 31, and the third edge 221, the fourth edge 231, and the fifth edge 31 extend into the receiving space 40 and are combined within the receiving space 40.
[0068] In one embodiment, the third edge 221, the fourth edge 231, and the fifth edge 31 are sewn together by stitching 42 within the receiving space 40.
[0069] In one embodiment, an extension range of the absorption layer 30 does not exceed a coverage range of the first region 22.
[0070] Please refer to FIGS. 5-7. FIG. 5 is a schematic diagram showing the front structure of an absorbent garment according to a second embodiment of the present application. FIG. 6 is a schematic diagram showing the inner structure of the crotch region of the absorbent garment according to the second embodiment. FIG. 7 is a cross-sectional schematic diagram of the absorbent garment according to the second embodiment taken along the crotch region.
[0071] As shown in FIGS. 5, 6, and 7, in the second embodiment of the present application, the absorbent garment may include a pants body 60, a base layer 70, and an absorption layer 80.
[0072] As shown in FIG. 5, the pants body 60 has an upper edge 61 for surrounding a wearer's waist during wearing, two leg openings 62 and 63 configured to allow the wearer's legs to pass through, and a crotch region 64 located between the two leg openings 62 and 63.
[0073] As shown in FIGS. 5, 6, and 7, the base layer 70 is combined with the pants body 60 at least on both sides of the crotch region 64. The base layer 70 and the pants body 60 enclose a receiving space 90, and the base layer 70 is configured to face toward the wearer's crotch during wearing. The pants body 60 has a first edge 65 on one side of the crotch region 64, and the base layer 70 has a second edge 71 corresponding to the first edge 65. The first edge 65 and the second edge 71 extend into the receiving space 90 and are sewn together by stitching 91 within the receiving space 90.
[0074] As shown in FIG. 7, the absorption layer 80 is located within the receiving space 90 and combined with the pants body 60.
[0075] As shown in FIG. 7, in one embodiment, the first edge 65 of the pants body 60 is folded and extends into the receiving space 90. In this manner, a smooth outer surface at the joint between the pants body and the base layer can be ensured, thereby improving wearing comfort.
[0076] As shown in FIG. 7, in one embodiment, the stitching 91 is concealed within the receiving space 90.
[0077] As shown in FIG. 7, in one embodiment, a width of the absorption layer 80 is smaller than a width of the crotch region 64, and edges of the absorption layer 80 do not extend to edges of the crotch region 64.
[0078] In one embodiment, the absorption layer 80 is combined with an inner surface of the pants body 60, and a position where the absorption layer 80 is combined with the pants body 60 is located at a non-edge position of the crotch region 64. The absorption layer 80 is sewn to the pants body 60 by stitching 500.
[0079] As shown in FIGS. 5, 6, and 7, in one embodiment, the absorbent garment further comprises a liquid barrier portion 200. The liquid barrier portion 200 is disposed on the base layer 70 and is located at side positions of the crotch region 64 near the leg openings 62, 63. The liquid barrier portion 200 is configured to protrude toward the wearer's crotch.
[0080] As shown in FIGS. 5, 6, and 7, in one embodiment, the liquid barrier portion 200 is a liquid barrier cotton strip 200 disposed on the base layer 70. Specifically, the liquid barrier portion 200 may be the liquid barrier cotton strip 200, whose operational mechanism is to form a three-dimensional embankment close to the body. When the wearer is in a supine or similar position, menstrual fluid may flow toward the thigh roots due to gravity. In such cases, the liquid barrier cotton strip 200 protruding from the surface of the base layer 70 can physically block the lateral spread of the liquid, confining it within the central absorption area enclosed by the liquid barrier portion 200 and the base layer 70, thereby significantly enhancing leakage protection during nighttime or while lying down. The liquid barrier cotton strip 200 is preferably made of a soft, highly elastic material, which provides effective blockage without creating hard pressure on the skin, ensuring wearing comfort.
[0081] As shown in FIGS. 5, 6, and 7, in one embodiment, the liquid barrier cotton strip 200 is bonded to the base layer 70 by an adhesive 300. For example, the liquid barrier portion 200 is bonded to the base layer 70 using hot-melt adhesive. It should be understood that, in other embodiments, the liquid barrier cotton strip may also be sewn onto the base layer 70 by stitching, which is not limited in the embodiments of the present application.
[0082] As shown in FIG. 7, in one embodiment, the liquid barrier cotton strip 200 is disposed on a surface of the base layer 70 facing the receiving space 90. In other embodiments, the liquid barrier portion may also be disposed on a side of the base layer 70 facing the wearer's crotch.
[0083] As shown in FIG. 7, in one embodiment, the absorbent garment further comprises a pants body waterproof layer 400 disposed on at least a portion of a surface of the pants body 60 facing the receiving space 90.
[0084] As shown in FIG. 7, in one embodiment, the liquid barrier portion 200 includes a convex portion 201 and an extension portion 202. The convex portion 201 protrudes toward the wearer's crotch, and the extension portion 202 is connected to the convex portion 201 and extends along a surface of the base layer 70. A thickness of the convex portion 201 is greater than a thickness of the extension portion 202. For example, the thickness of the convex portion 201 may be between 3 mm and 6 mm, and the thickness of the extension portion may be between 1 mm and 2 mm.
[0085] As shown in FIG. 7, in one embodiment, there are two extension portions 202, which extend along the two sides of the convex portion 201, respectively. The function of the extension portion(s) 202 is to increase the overall contact area between the liquid barrier portion 200 and the base layer 70, thereby making the bonding or sewing of the liquid barrier portion 200 to the base layer 70 more secure.
[0086] As shown in FIG. 7, in one embodiment, an extension range of the absorption layer 80 does not cover the location of the convex portion 201. In this manner, liquid from within the absorption layer 80 does not backflow to the convex portion 201, reducing the leakage prevention burden on the liquid barrier portion 200.
[0087] As shown in FIG. 7, in one embodiment, there are two liquid barrier portions 200, which are respectively disposed on the base layer 70 at positions corresponding to the two sides of the crotch region 64.
[0088] As shown in FIGS. 5, 6, and 7, in one embodiment, the liquid barrier portion 200 extends in a strip-like manner along the wearer's groin during wearing.
[0089] The absorbent garment according to any embodiment of the present application is configured to be reusable and washable multiple times.
[0090] The absorbent garment according to an embodiment of the present application comprises: a pants body having an upper edge for surrounding a wearer's waist during wearing, two leg openings configured to allow the wearer's legs to pass through, and a crotch region located between the two leg openings; a base layer combined with the pants body at least on both sides of the crotch region, wherein the base layer and the pants body enclose a receiving space, and the base layer is configured to face toward the wearer's crotch during wearing; the pants body has a first edge on one side of the crotch region, the base layer has a second edge corresponding to the first edge, and the first edge and the second edge extend into the receiving space and are sewn together by stitching within the receiving space; and an absorption layer located within the receiving space and combined with the base layer or the pants body. In this manner, the first edge and the second edge extend into the receiving space and are sewn together by stitching within the receiving space. This stitching method provides better breathability, thereby avoiding the lack of breathability caused by adhesive bonding. It also prevents the issue of difficulty in drying after washing, as well as the problem of adhesive degradation due to washing or drying. Furthermore, since the first edge and the second edge extend into the receiving space and are sewn together within it, the stitching is not exposed and does not cause uncomfortable friction against the wearer's crotch. Consequently, wearing comfort is improved, drying after washing is facilitated, adhesive failure is avoided, and the service life of the garment is enhanced.
