FIELD: physics.
SUBSTANCE: first exemplary absorbent core can comprise a bearing sheet having a first edge region, a central region and a second edge region, and a granular material arranged on the bearing sheet in the first edge region, the central region and the second edge region. Absorbent core can additionally have width of absorbent core, and central area can have width of central area, and central width can be from 33 % to 75 % of width of absorbent core. Besides, central area may have average density of granular material making at least 110 % of average density of granular material in at least one of left edge area and right edge area.
EFFECT: cellulose free absorbing cores and methods for their manufacture are described.
