ABSORBENT PRODUCT Russian patent published in 2021 - IPC A61F13/511 

FIELD: absorbent products.

SUBSTANCE: disclosed is an absorbent product including a sheet (10) with protrusions and recesses as a component, wherein the absorbent product has a longitudinal direction and a width direction orthogonal to the longitudinal direction. The sheet (10) with protrusions and recesses has multiple recesses (3) and protrusions (4) on the surface facing the skin, subject to being brought into contact with the skin of the wearer. In a given direction, the range of possible movement of the top (40) of the protrusion (4) of the sheet (10) with protrusions and recesses is 30% or more of the length (L2) in said given direction of the lower part of the protrusion (4). On the surface of the sheet (10) with protrusions and depressions facing the skin, the average friction coefficient MIU in the longitudinal direction (X) equals 0.3 or less, and the difference in the friction coefficient between the forward stroke and the reverse stroke when moving backward and forward along the longitudinal direction (X) is less than 0.1. The sheet (10) with protrusions and recesses is characterised by operation under compression of 2.0 mN∙cm/cm² or more, and has a compression recovery rate of 40% or more.

EFFECT: creation of an absorbent product comprising a sheet with protrusions and recesses.
