Embodiment 1

[0039] See figure 1 , Figure 4 , the present embodiment provides a sanitary napkin, the body part of the sanitary napkin includes a surface layer 4 and an absorbent core in sequence from top to bottom, and a bottom film 5 is provided at the bottom of the absorbent core. Wherein, the surface layer 4 is made of non-woven fabric and is fixedly connected with the absorbent core through peripheral bonding, and the two are filled with cotton wool with water absorption and cushioning functions; the bottom film 5 is made of PE film material, and The bottom of the absorbent core is fixedly connected.

[0040]Specifically, the absorbent core includes a central absorbent area 1 and a peripheral absorbent area 2. The central absorbent area 1 is arranged in a strip shape from front to back, with a length of 100 mm, a width of 30 mm, and a thickness of 4 mm; The absorbent area 2 is arranged around the central absorbent area 1, and its shape is similar to that of a conventional sanitary n...

Abstract

The invention relates to the field of hygienic products, and discloses an absorption core body and an application thereof. The absorption core comprises a central absorption area and a peripheral absorption area, the peripheral absorption area is arranged around the central absorption area, the vertical height of the central absorption area is lower than that of the peripheral absorption area, anda plurality of holes are formed in the central absorption area and the peripheral absorption area in the height direction. According to the absorption core body disclosed by the invention, a sanitarynapkin absorption core body integrally forms a concave structure with a flat outer part and a concave inner part, so that a menstrual blood storage and absorption space with a larger volume is created; and the diameters of the holes of the central absorption area and the peripheral absorption area are changed in the height direction, so that the comfort of a user is guaranteed while the absorption rate is increased and the upward reverse osmosis of menstrual blood is reduced according to the actual situation.

Description

technical field [0001] The invention relates to the field of hygienic products, and more specifically relates to an absorbent core and its application. Background technique [0002] Fertile women experience spontaneous thickening of the endometrium, proliferation of blood vessels, growth and secretion of glands, collapse and shedding of the endometrium with bleeding, usually 2-7 days, most of them 3-5 days , Menstrual blood will be excreted from the body during menstruation, and disposable absorbent products need to be used to absorb menstrual blood during this period. [0003] At present, disposable sanitary napkins are usually used to absorb menstrual blood in the market. Sanitary napkins are mainly divided into sanitary napkins, menstrual pants or tampons, and various styles of sanitary napkins have their own characteristics. [0004] Among them, sanitary napkins and their absorbent cores are usually of planar structure, and they are attached to underwear with adhesive b...
