Abstract
An absorbent structure including a composite absorbent laminate is disclosed, with the structure suitable for use in disposable absorbent products such as for infant or incontinence care. Notably the laminate comprises discrete acquisition cells each comprising particles of preferably cellulosic absorbent material. The absorbent structure further comprises particulate superabsorbent polymer which can either be blended with the particulate discrete acquisition cells in the absorbent laminate, or provided in a separate absorbent layer of the absorbent structure. The discrete acquisition cells desirably generate free volume for rapid capillary absorption in an ultra-thin absorbent structure.
