FIELD: medicine.

SUBSTANCE: structure of an absorbent core for disposable absorbent products. The absorbent core for the absorbent product contains a first layer, which contains first and second surfaces of the first layer; an absorbent polymer layer, which comprises first and second absorbent polymer layers; an adhesive layer. The adhesive layer comprises first and second surfaces of the adhesive layer. The absorbent polymer layer is arranged between the adhesive layer and the first layer. The second surface of the absorbent polymer layer faces the first surface of the above first layer; and the first layer of the absorbent polymer layer faces the second surface of the above adhesive layer. The structure of the absorbent core comprises a second layer, having first and second surfaces respectively and arranged so that the second surface of the second layer faces the first surface of the adhesive layer. The first layer of the absorbent core is characterised by the thickness of 0.4 mm to 1.5 mm, while the second layer of the absorbent core is characterised by a permeability of at least 200 Darcy and a porosity of at least 0.85.

EFFECT: providing an increase of absorptive capacity, low re-soaking, fast fluid collection with a small thickness of the product.
