Abstract
The laminated absorbent structure has absorbent gelling material (26) and a first odour absorber (24) each held between separate containing layers (2,4,6). The absorbent gelling material also separates a fluid-receiving surface from the first odour absorber. A second absorber may be a coating sprayed onto the layer (2) so that it is between the gelling material and the first surface. The first absorber is active when not wetted and the second odour absorber is active when wetted. The containing layers are fibrous layers and absorbent gelling material and the odour absorbers are in particle or powder form.
