Description

Technical Field

[0001] This utility model relates to the field of clothing technology, and in particular to a close-fitting garment with leak-proof, moisture-wicking and breathable functions. Background Technology

[0002] Underwear is one of the garments we wear close to our skin every year. With the improvement of living standards, there are various materials, fabrics and styles of underwear on the market.

[0003] Underwear is generally required to be comfortable and breathable. Most are made of pure cotton knitted material, which is comfortable and breathable. However, because pure cotton knitted material is highly permeable, if there is incomplete urination, incontinence, or discharge, the underwear may seep through and stain the outer pants or clothes, causing an embarrassing situation and inconvenience.

[0004] Some underwear products incorporate a waterproof layer made of a waterproof material in a specific area. For example, patent CN202121132167.5 discloses waterproof men's underwear, which includes an underwear body. The underwear body has a front center panel covering its front center portion, and the waterproof layer is located on the inner side of the front center panel between the front center panel and the front center portion of the underwear body. This waterproof layer is made of silicone. The problem with this product is that while silicone is highly waterproof, it neither absorbs nor drains liquid. Any spilled liquid will leak from the sides or legs, making it a temporary solution that doesn't address the root cause of the problem and doesn't completely solve the user's biggest concern. Summary of the Invention

[0005] This invention addresses the above problems by proposing a method that rapidly absorbs and releases moisture, using an internal hollow fiber structure to absorb and guide liquid to a non-skin contact surface, and then utilizes the hollow effect to release moisture. This fundamentally solves a certain degree of urinary leakage problems without causing side leakage or overflow.

[0006] A leak-proof pair of underwear, characterized in that the underwear includes an underwear body, the underwear body comprising a front panel, a back panel and a crotch portion, wherein the crotch is located between or within the front panel and the back panel, and the crotch is made of a multi-layer fabric composite, including a first hollow quick-drying layer, a second moisture-wicking layer and a third fabric layer.

[0007] The second absorbent layer is made of a spiral mesh fabric.

[0008] The second moisture-absorbing layer consists of 1-3 layers of spiral mesh fabric stacked together.

[0009] The first hollow quick-drying layer is made of a blend of hollow yarn and cotton yarn.

[0010] The cotton yarn used is modal yarn.

[0011] The first hollow quick-drying layer is composed of a blend of hollow yarn and cotton yarn in a ratio of 30:70 to 45:55.

[0012] The hollow yarn is a hollow yarn with a cross-shaped cross section.

[0013] When the leak-proof underwear is men's underwear, the front and back panels are sewn together to form a waistband and two pant legs, while the crotch is located in the center of the front panel. The crotch contains a four-layer structure, from the inside out: a first hollow quick-drying layer, a second moisture-wicking layer, a third moisture-wicking layer, and a fourth fabric layer. The fourth fabric layer is the same as the fabric of the front and back panels.

[0014] The second and third absorbent layers are not completely sewn together, leaving a space in the middle.

[0015] When the leak-proof underwear is women's underwear, the front and back panels are connected together by a mid-crotch stitch, forming a waistband and two pant legs. The mid-crotch contains four layers, from the inside out: a first hollow quick-drying layer, a second moisture-wicking layer, a third moisture-wicking layer, and a fourth fabric layer. The fourth fabric layer is the same as the fabric of the front and back panels.

[0016] The leak-proof underwear involved in this utility model is designed to quickly absorb and wick away moisture. It absorbs and guides liquid to the non-skin contact surface through the internal hollow fiber structure, and then uses the hollow effect to wick away moisture. This can fundamentally solve the problem of urinary leakage to a certain extent, which is sufficient to meet the needs of general daily wear. It can also effectively reduce the possibility of side leakage and avoid embarrassing situations. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Please refer to the attached diagram in the instruction manual, which shows a leak-proof underwear. It mainly uses a hollow fabric layer to quickly absorb and guide overflowing body fluids to the second layer structure, preventing liquid from adhering to the fabric part in contact with the skin and keeping the skin surface dry and comfortable. Example 1:

[0026] A leak-proof underwear 100 is characterized in that the underwear includes an underwear body, which comprises a front panel 10, a back panel 20, and a crotch 30. Since this embodiment 1 is based on the style of men's underwear, structurally, the front panel 10 and the back panel 20 are sewn together to form a waistband 200 and two pant legs 300, while the crotch 30 is located in the center of the front panel 10. The crotch 30 comprises a four-layer structure, which, from the inside out, are a first hollow quick-drying layer 31, a second moisture-absorbing layer 32, a third moisture-absorbing layer 33, and a fourth fabric layer 34. The fourth fabric layer 34 is made of the same fabric as the front panel 10 and the back panel 20.

[0027] From a cost perspective in industrial manufacturing, the fourth fabric layer should generally be consistent with the front 10 and back 20 layers, which is the most practical and economical approach. Of course, if there are other design considerations, different fabrics can be used without affecting the overall functional effect.

[0028] The second absorbent layer 32 is made of a spiral mesh fabric.

[0029] The second absorbent layer 32 is composed of 1-3 layers of spiral mesh fabric. In this embodiment, two layers of spiral mesh fabric are used, resulting in a second absorbent layer 32 and a third absorbent layer 33. Furthermore, the second absorbent layer 32 and the third absorbent layer 33 are not completely sewn together, leaving a middle channel space 400.

[0030] This design provides superior moisture absorption and wicking. If a person wearing leak-proof underwear experiences minor urination, the liquid will immediately flow to the first hollow quick-drying layer 31 (middle layer 30). The hollow yarns within this layer quickly draw the liquid away from its inner surface, transferring it to the second and third moisture-absorbing layers 32 and 33. These layers, while absorbing and storing moisture, also utilize the space between them to allow airflow and evaporation of some moisture during movement, thus eliminating it as gas. Overall, this results in a very effective leak-proof solution.

[0031] The first hollow quick-drying layer 31 is made of a blend of hollow yarn 311 and cotton yarn 312.

[0032] The cotton yarn 312 is modal yarn. Other cotton yarns can also be used to make it.

[0033] The hollow yarn 311 and cotton yarn 312 in the first hollow quick-drying layer 31 are blended in a ratio of 30:70 to 45:55.

[0034] The hollow yarn 311 is a hollow yarn with a cross-shaped cross section. Example 2:

[0035] In this embodiment, the leak-proof underwear is a women's underwear. The front panel 10 and the back panel 20 are sewn together by the crotch 30 to form a waistband 200 and two pant legs 300. The crotch 30 has a three- or four-layer structure. When the crotch has a four-layer structure, from the inside to the outside, it consists of a first hollow quick-drying layer, a second moisture-absorbing layer, a third moisture-absorbing layer, and a fourth fabric layer. The fourth fabric layer is the same as the fabric of the front panel and the back panel.

[0036] The function and application principle are the same as in Example 1. If a person wearing leak-proof underwear experiences a small amount of urine leakage, the liquid will flow to the first hollow quick-drying layer 31 of the middle layer 30 immediately. The hollow yarn inside the first hollow quick-drying layer 31 will quickly absorb and guide the liquid from the inner surface and transfer it to the second moisture-absorbing layer 32 and the third moisture-absorbing layer 33. The second moisture-absorbing layer 32 and the third moisture-absorbing layer 33 can absorb and store a certain amount of moisture to keep the surface of the first hollow quick-drying layer 31 that is in contact with the human skin dry and comfortable.

[0037] The leak-proof underwear involved in this utility model is designed to quickly absorb and wick away moisture. It uses an internal hollow fiber structure to absorb and guide liquid to the non-skin contact surface, and then utilizes the hollow effect to wick away moisture. This can fundamentally solve the problem of urinary leakage to a certain extent. It can be widely used among the general population and can meet the general daily wear needs. When there is a small amount of leakage, it can reduce the problem of side leakage and avoid embarrassing situations to the greatest extent.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
