DISPOSABLE ABSORBENT HYGIENIC PRODUCT CONTAINING AN ABSORBENT UNIT Russian patent published in 2021 - IPC A61F13/53 

FIELD: hygiene.

SUBSTANCE: proposed is a disposable absorbent hygienic product (1) containing a main part (10) with a surface facing the body and intended to be facing the body of the user and a surface facing the article of clothing and intended to be facing away from the body of the user, wherein the main part comprises a liquid-permeable top sheet (11) on the surface facing the body, a liquid-impermeable bottom sheet (12) on the surface facing the article of clothing, and an absorbent unit (13) located between the top sheet and the bottom sheet, wherein the main part has a front end (14) and a back end (15) and determines the longitudinal direction (L) from said front end to said back end, and determines the transverse direction (T) perpendicular to the longitudinal direction, wherein the absorbing unit (13) is divided by two imaginary lines (T1, T2) extending in the transverse direction into a front area (Rf) located closer to said front end, with a length in the longitudinal direction constituting from 10 to 40% of the length of the absorbent unit in the longitudinal direction, a back area (Rb) located closer to said back end, with a length in the longitudinal direction constituting from 10 to 40% of the length of the absorbent unit in the longitudinal direction, and a central area (Rc) between said front area and said back area, wherein the absorbent unit contains cellulose fibres in the front and back areas, if necessary, mixed with polymers with ultra-high absorbency at a concentration of the polymer with ultra-high absorbency from 0 to 30 wt.% of the total weight of the cellulose fibres and the polymer with ultra high absorbency, and at a surface density of the cellulose fibres constituting 50 to 200 g/m², wherein said central area provides 70% to 100% of the total retaining capacity of the absorbent unit, wherein the material of the liquid-permeable top sheet contains a polypropylene spunbonded non-woven fabric or a non-woven composite material consisting of spunbonded non-woven fabric and a non-woven material obtained by the aerodynamic method from a melt, treated to impart hydrophilicity, with a surface density of 8 to 20 g/m², and a material of the receiving layer is therein provided, placed between the top sheet and said absorbent unit and constituting a non-woven material, sealed by air passed therethrough, with a surface density of 40 to 60 g/m² and a thickness of at least 0.9 mm measured in accordance with the method NWSP 120.6, variant A, at a pressure of 0.5 kPa.

EFFECT: technical result is production of a wearable absorbent product.
