Abstract

An absorbent element for absorbent articles comprised of hydrophilic fibers and a discontinuous, non-uniform layer of particles of absorbent hydrogelling material arranged on the upper surface of the element includes a deposition zone on which the absorbent hydrogelling material is distributed with an increased surface density. The zone of increased surface density of the absorbent hydrogelling material can preferably be located in different positions suitable for the different anatomical forms of the users, so as to ensure more effective sealing against the backflow of the liquid and thus ensure an improved feeling of dryness.
