Description

Technical Field

[0001] This utility model relates to the field of hygiene products technology, and in particular to a menstrual pant with a full hemp surface. Background Technology

[0002] Menstrual panties, also known as panty-style sanitary napkins, are a type of personal hygiene product that comes into direct contact with the body. Similar to sanitary napkins, menstrual panties are increasingly favored by female consumers due to their superior absorbency, coverage, leak-proof properties, and overall protection against seepage. However, while providing women with a sense of security and comfort, menstrual panties also have the following drawbacks. The main reasons are: the stuffy feeling caused by prolonged wear of existing menstrual panties can lead to skin allergies, and bacterial growth can harm health – issues that urgently need to be addressed. Utility Model Content

[0003] In view of this, in order to solve the problems existing in the technical background, this utility model proposes a menstrual pant with an all-hemp surface, the specific technical solution of which is as follows:

[0004] A menstrual panty with an all-hemp surface layer includes an all-hemp surface layer menstrual panty body. The all-hemp surface layer menstrual panty body is an underwear shape made of non-woven fabric and elastic band through cutting and bonding. The all-hemp surface layer menstrual panty body consists of, from the skin-contacting side downwards, a surface layer, a diversion layer, an absorbent body, a leak-proof bottom membrane, and an elastic wrapping body. The surface layer is made of all-hemp non-woven fabric.

[0005] Furthermore, the absorbent is formed by overlapping and laying down a thin layer of hemp fiber, a thin layer of wood pulp, and a thin layer of superabsorbent polymer.

[0006] Furthermore, the leak-proof bottom membrane is a breathable bottom membrane.

[0007] Furthermore, the elastic enclosure is made of ultra-soft nonwoven fabric.

[0008] Furthermore, the hemp fiber thin layer is made of hemp fiber material.

[0009] Furthermore, the superabsorbent polymer (SAP) thin layer is made of SAP.

[0010] Furthermore, the flow guiding layer is made of high-loft coarse denier hot air nonwoven fabric.

[0011] The above technical solution has the following beneficial effects:

[0012] The outer layer of this invention is a non-woven fabric made entirely of hemp fiber. Hemp fiber is a natural plant fiber that can destroy the bacterial cell structure, making it impossible for anaerobic bacteria to survive. Hemp fiber has moisture-wicking and quick-drying properties, and a dry environment is also not conducive to bacterial growth. The multi-layered flat structure of the absorbent material quickly pulls menstrual blood to the bottom, resulting in good absorption. Hemp fiber can effectively inhibit bacterial growth and prevent bacteria from multiplying upwards, avoiding contact with the skin and causing skin or gynecological diseases, thus meeting women's needs for menstrual underwear.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Example 1: As Figure 1-3 The illustrated menstrual panties with an all-hemp surface include an all-hemp surface menstrual panty body 1. The all-hemp surface menstrual panty body 1 is an underwear shape made of non-woven fabric and elastic band through cutting and bonding. The all-hemp surface menstrual panty body 1 consists of, from the skin-contacting side downwards, a surface layer 2, a diversion layer 3, an absorbent body 4, a leak-proof bottom membrane 5, and an elastic wrapping body 6. The surface layer 2 is made of all-hemp non-woven fabric.

[0020] The absorbent body 4 is made of overlapping and flat layers of hemp fiber thin layer 43, wood pulp thin layer 41 and superabsorbent polymer thin layer 42. The leak-proof bottom membrane 5 is a breathable bottom membrane. The elastic surrounding body 6 is made of ultra-soft non-woven fabric. The hemp fiber thin layer 43 is made of hemp fiber. The superabsorbent polymer thin layer 42 is made of superabsorbent polymer. The flow guiding layer 3 is made of high-loft coarse denier hot air non-woven fabric.

[0021] In this embodiment, the surface layer 2 is made of non-woven fabric made entirely of hemp fiber. Hemp fiber is a natural plant fiber with better skin-friendliness, improving comfort during use. Hemp fiber contains phenolic substances and their derivatives, organic acids, and inorganic salts, which can disrupt the cell structure of bacteria. In addition, the porous structure of hemp fiber allows the fiber to be filled with air, thus being rich in oxygen, making it impossible for anaerobic bacteria to survive. Hemp fiber also has moisture-wicking and quick-drying properties, and a dry environment is also unfavorable for bacterial growth.

[0022] In this embodiment, the flow guiding layer 3 is made of high-loft coarse denier hot air nonwoven fabric, which guides the flow and prevents back seepage, forming a spatial barrier.

[0023] like Figure 3 The absorbent 4 shown is made of hemp fiber thin layer 43, wood pulp thin layer 41 and super absorbent polymer thin layer 42, which are laid flat and overlapped with each other. The wood pulp thin layer 41 absorbs liquid faster than the super absorbent polymer thin layer 42. The wood pulp first grabs liquid, but it also releases liquid quickly. Therefore, the wood pulp layer is laid flat, and a super absorbent polymer thin layer 42 with good absorption speed is laid underneath to absorb and lock in the liquid, so that the urine is guided to the bottom layer and there is a certain space barrier between the urine and the baby's bottom.

[0024] In this embodiment, the anti-leakage bottom membrane 5 is a breathable bottom membrane, which reduces moisture penetration while maintaining good breathability and reducing stuffiness.

[0025] In this embodiment, the elastic enclosure 6 is made of ultra-soft non-woven fabric, which is fluffy and soft, making it more comfortable to use.

[0026] When using the menstrual pants, insert the holes on both sides of the hemp-faced menstrual panty body 1 into the user's legs, and manually lift the hemp-faced menstrual panty body 1 upwards until it completely fits the upper part of the legs. The hemp fiber surface 2 of the hemp-faced menstrual panty body 1, which is in contact with the user's skin, is made of antibacterial material and hemp fiber, which can improve the dryness, breathability, antibacterial properties and comfort of the menstrual panty.

[0027] In summary, the surface layer 2 of this utility model is a non-woven fabric made entirely of hemp fiber. Hemp fiber is a natural plant fiber that can destroy the bacterial cell structure, making it impossible for anaerobic bacteria to survive. Hemp fiber has moisture-wicking and quick-drying properties, and a dry environment is also not conducive to bacterial reproduction. The multi-layer flat structure inside the absorbent body 4 quickly pulls menstrual blood to the bottom, resulting in good absorption. Hemp fiber can effectively inhibit bacterial growth and prevent bacteria from multiplying upwards, avoiding contact with the skin and causing skin or gynecological diseases, thus meeting women's needs for menstrual underwear.

[0028] In specific use, the basic principles and main features of this utility model have been described above. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
