DISPOSABLE ABSORBENT HYGIENE PRODUCT CONTAINING ABSORBENT UNIT Russian patent published in 2021 - IPC A61F13/532 

FIELD: hygiene products.

SUBSTANCE: disposable absorbent hygiene product (1) is proposed, containing main part (10) having a surface facing the body, which is intended to be facing the user's body, and a surface facing the clothes, which is intended to be facing away from the user's body. The main part contains liquid-permeable upper sheet (11) on the surface facing the body, non-liquid-permeable lower sheet (12) on the surface facing the clothes, and absorbent unit (13), located between the specified upper sheet and the specified lower sheet. The specified main part has front end (14) and back end (15) and determines longitudinal direction (L) from the specified front end to the specified back end and transverse direction (T) perpendicular to the longitudinal direction. Absorbent unit (13) contains first absorbent core (131) and second absorbent core (132) superimposed on each other. Specified first absorbent core (131) has length (L_abs) in the longitudinal direction, of 500 to 1000 mm and width (W_abs) in the transverse direction of 200 to 450 mm. It contains cellulose fibers, mixed with ultra-high absorbency particles, if necessary, and has a concentration of ultra-high absorbency particles of 0 to 30 wt.% and a surface density of cellulose fibers of 50 to 200 g/m². Specified second absorbent core (132) has a length in the longitudinal direction of 20 to 80% of length (L_abs) of the specified first core and contains a mixture of cellulose fibers and ultra-high absorbency particles at a concentration thereof ranging from 20 to 70 wt.% and a surface density of cellulose fibers ranging from 250 to 500 g/m². The ends of the second core, determined in the longitudinal direction, are located between the ends of the first core, determined in the longitudinal direction.

EFFECT: technical result is obtaining a disposable absorbent hygiene product.
