Description

Absorbent article Technical Field The utility model relates to the field of absorbent articles, in particular to an absorbent article such as a sanitary towel, a protection pad, a paper diaper and the like. Background Absorbent articles such as sanitary napkins, panty liners, and diapers are widely used in the daily life of people and generally comprise a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core sandwiched between the topsheet and the backsheet. In order to increase the absorption rate, at present, the absorption rate is usually increased by pressing, for example, channels or a grid structure on the absorbent article so that the density of the area of the absorbent article corresponding to the channels or the grid structure is increased and the diameter of the capillaries is reduced, and in this form, the channels and the grid structure are usually arranged on the surface layer, and presents a groove structure in the direction from the top layer to the bottom layer, but in such a structure, there is still a problem that the absorption capacity is insufficient, and particularly, when the flow rate of the body fluid is large, the body fluid is easily concentrated in the middle region, and particularly, when the body fluid is thick menstrual blood, the body fluid is more easily adhered to the skin or the use is uncomfortable due to the insufficient absorption rate. In this case, one solves the above-mentioned problems by forming openings in the facing layer in the form of structures as shown in the documents CN221751165U, CN221672331U, WO2024065584A1 and the like, but these structures usually employ the through-holes of the facing layer directly corresponding to the absorbent layer or further also form openings corresponding to the above-mentioned through-holes in the absorbent layer, which on the one hand results in an increase in rewet and on the other hand, after which the absorption rate of body fluid in the thickness direction increases, but the upward diffusion capacity in the planar direction decreases considerably, and the absorption capacity of other areas is not utilized further, resulting in an overall insufficient absorption capacity. Accordingly, there is a need to provide an improved solution to the above-mentioned technical problems. Disclosure of utility model To this end, the present utility model provides an absorbent article to solve the above technical problems.
