摘要： The invention provides an absorbent material or article comprising an absorbent hydrogel composite sheet. The sheet includes an absorbent layer part having two major faces which comprises a flexible plasticised hydrophilic polymer matrix having an internal cellular structure, and a second part which comprises a flexible plasticised hydrophilic polymer matrix having a relatively continuous internal structure. The second part may be associated with the layer part such that the second part infiltrates some but not all of the cellular voids of the absorbent layer part over a major face of the absorbent layer part. Alternatively, the second part may be associated with the layer part such that the second part overlies a major face of the absorbent layer part. By this arrangement, some but not all of the absorbent layer part is effectively exposed for absorption of external water or other fluid through the side of the sheet corresponding to that said major face of the absorbent layer.
