[0032] A physiological period underwear, as Figures 1-7 shown, includes an underwear body 10. The crotch 100 of the underwear body is at least a three-layer structure, including a water guiding layer 101, a water storage layer 102, and a waterproof layer 103.
[0033] With this water guiding and water locking structure, firstly, it can guide and absorb water, creating a comfortable user experience. The crotch of the underwear has good water absorption, water locking, non-backflow of absorbed water, and non-leakage effects, effectively solving the concerns during a female's physiological period, reducing the dampness and heat between the underwear and the body, and maintaining a dry and fresh feeling. Secondly, it can lock water, locking the water between the interlayers, preventing backflow and leakage, and avoiding soiling clothes and sheets. Further, an independently provided water guiding layer 101 can be included. The water guiding layer 101 can be set as a unidirectional water permeable and guiding membrane body or another water guiding layer to further prevent liquid backflow.
[0034] In a preferred embodiment, it further includes an inlaid structure 108 arranged on both sides of the crotch 100. The inlaid structure is at least composed of the parts where the water guiding layer 101 and the waterproof layer 103 are folded back respectively. The folded part of the waterproof layer 103 is located outside the folded part of the water guiding layer 101. It can wrap the water absorbed between the water guiding layer 101 and the water storage layer 102 by the waterproof layer 103, thereby further preventing side leakage along the edge of the underwear. The built-in rubber ring 106 formed by folding the waterproof layer 103 back can also generate a certain height, thus forming a convex edge to create a protective body feeling and an anti-side leakage effect.
[0035] In a preferred embodiment, glue 105 is used for bonding and fixing inside the inlaid structure. The glue is hidden between the outer surfaces of the water guiding layer 101 and the waterproof layer 103. By the hidden glue, on the one hand, the structure between different cloth layers is fixed, on the other hand, the irritation to the skin caused by the position of the glue is reduced, and the overall appearance is also made more beautiful. In this embodiment, the folded part of the water guiding layer 101 is also bonded and fixed with glue 105, and the folded part of the waterproof layer 103 is also bonded and fixed with glue 105.
[0036] In a preferred embodiment, a rubber strip 107 is embedded in the edge of the crotch 100. The rubber film structure can provide a certain structural shape, making the underwear not easily deformed. At the same time, the rubber strip 107 provided at the edge makes the underwear have better wrapping property, can more smoothly adapt to the activities of the inner thigh, and makes the fixation of the sanitary napkin or menstrual pad more firm. In the specific implementation process, the rubber strip 107 is a rubber film strip or a glue strip.
[0037] In a preferred embodiment, the waterproof layer 103 is a knitted fabric made of cotton yarn provided with a water-repellent finishing agent or a water-repellent finishing film. The waterproof coating or film can prevent a large amount of menstrual blood from flowing to the outside.
[0038] In a preferred embodiment, the water-conducting layer 101 is a knitted fabric with a unidirectional conduction structure. While enabling the menstrual blood to be quickly absorbed, it can prevent backflow and secondary pollution. The water-conducting layer 101 can be provided with multiple layers.
[0039] In a preferred embodiment, an enclosed area connected end to end by a rubber strip 107 is provided in the middle section of the crotch 100. As Figure 2 shown, this enclosed area is used to seal the key menstrual occurrence area and control the diffusion direction of menstrual blood in a graded manner, making the overall water absorption more uniform, rather than the water absorption phenomenon occurring on one side of the underwear.
[0040] In a preferred embodiment, a convex core 200 is provided in the central section of the crotch 100. As Figure 6 shown, the convex core 200 can be made of water-absorbing materials such as cotton or water-absorbing cloth. The convex core 200 uses a molded three-dimensional shape to conform to the body curve to block the key menstrual occurrence area and control the diffusion direction of menstrual blood in a graded manner, making the overall water absorption more uniform and preventing penetration and soiling of clothes.
[0041] In a preferred embodiment, a number of water-blocking bosses 109 are provided on the convex core 200. As Figure 6 shown, the water-blocking bosses 109 enclose an area to seal the key menstrual occurrence area and control the diffusion direction of menstrual blood in a graded manner, preventing penetration and soiling of clothes.
[0042] In a preferred embodiment, a decorative layer 104 is provided on the inner surface and / or outer surface of the underwear body. As Figure 7 shown, decorative layers for decorative purposes can be added to both the inner and outer layers as needed to achieve an aesthetic effect. Preferably, the decorative layer is a knitted fabric of skin-friendly material.
[0043] The embodiments of the present utility model have been described above. The above description is exemplary and not exhaustive, and is also not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other ordinary skill in the art to understand the embodiments disclosed herein.
