Abstract
An absorbent element for disposable absorbent articles composed of hydrophilic fibres and a discontinuous layer of particles of a hydrogelling absorbent material disposed on the upper surface of the element including two side regions situates at least in correspondence with the central part of the element, in which the hydrogelling absorbent material is distributed at a greater concentration on the surface or within the element. When the absorbent element is used as an absorbent pad for disposable diapers, the two side regions are situated at least in the crutch region of the diaper so as to ensure more effective lateral leak-proofing.
Claims22
An absorbent element made from hydrophilic fibres comprising in combination:
- a discontinuous layer of hydrogelling absorbent material distributed at a concentration between 5 g/m.sup.2 and 70 g/m.sup.2 on an upper surface thereof facing the user, and a region along each of laterally opposed longitudinal edges having a high concentration of hydrogelling absorbent material distributed at a concentration of between 100 g/m.sup.2 and 300 g/m.sup.2.
An absorbent article including a lower impermeable plastics sheet, an upper permeable non-woven sheet textile, and an absorbent element between the plastics sheet and the non-woven sheet, wherein the absorbent element is made from hydrophilic fibres and has longitudinal edges, and wherein a discontinuous layer of hydrogelling absorbent material distributed at a concentration of between 5 g/m.sup.2 and 70 g/m.sup.2 is on the upper surface of the absorbent element which faces the user, and a region along each of said longitudinal edges wherein a high concentration of hydrogelling absorbent material is distributed at a concentration of between 100 g/m.sup.2 and 300 g/m.sup.2 .
