Technical Field
[0001] This utility model belongs to the technical field of women's hygiene products, and in particular relates to a silver-based fiber antibacterial quick-absorbing and odor-removing overnight panty. Background Technology
[0002] Overnight panties, also known as night panties, are sanitary products for women. They are suitable for women to wear at night during their menstrual period. Because overnight panties have a large absorption capacity, wearing them can solve the problem of frequently changing sanitary pads at night. At the same time, compared with sanitary pads, overnight panties can also solve the problem of menstrual blood leakage at night. Therefore, overnight panties have been favored by many women.
[0003] Overnight pants include a pant body with a top layer that adheres to the skin and a bottom layer on the outside of the pant body. An absorbent core is located between the top and bottom layers to absorb and store menstrual blood. To prevent blood absorbed by the absorbent core from seeping to the outside of the pant body, a breathable overnight pant body, as disclosed in patent application number 202220659785.3, includes a pant body with a bottom layer and a top layer. An absorbent core is located in the crotch area between the bottom and top layers. The bottom layer of the pant body is made of water-repellent non-woven fabric, and multiple leak-proof layers are provided between the water-repellent non-woven fabric in the crotch area and the absorbent core. This solution improves the breathability of the overnight pant body while ensuring its ability to prevent blood from seeping to the outside. However, this structure has poor antibacterial properties and is prone to odor when used in summer, therefore, improvement is needed. Utility Model Content

[0027] Please see Figure 1-4As shown in this embodiment, a silver-based fiber antibacterial quick-absorbing and odor-removing overnight pant includes a pant body 1. The pant body 1 includes a front waistband 101, a back waistband 102, and a crotch area 103. In this embodiment, the layer structure of the pant body 1 is as follows: the pant body 1 has a bottom layer 10 and a top layer 11. An absorbent core 2 is located in the crotch area 103 of the pant body 1 between the bottom layer 10 and the top layer 11. The bottom layer 10 of the pant body 1 is made of water-repellent non-woven fabric, and the top layer 11 is made of skin-friendly fabric. In this embodiment, the bottom layer of the pant body 1 is made of water-repellent non-woven fabric to improve waterproofness and avoid leakage. A left elastic strip 104 and a right elastic strip 105 that are detachably attached are respectively provided on both sides of the front waistband 101. Double-sided adhesive strips 106 are provided on both the left elastic strip 104 and the right elastic strip 105. An absorbent core 2 is provided inside the crotch area 103. The core 2 has a silver-based fiber antibacterial and absorbent layer 3 on the side of the crotch 103 facing the skin, a mint fiber antibacterial layer 4 on the side of the front waistband 101 facing the abdomen, and an arc-shaped negative ion antibacterial layer 5 on both sides of the crotch 103 facing the buttocks. The outer ring of the absorbent core 2 has an odor-absorbing loop 6 to further enhance the odor absorption effect. The odor-absorbing loop 6 includes an upper loop layer 7, a middle odor-absorbing particle 8, and a lower waterproof layer 9.
