COMPOSITE ABSORBENT STRUCTURE AND METHOD

摘要

An absorbent structure and method utilizes pockets or pouches (31) of inorganic or organic granular materials (34) in absorbent structures (such as a structure containing superabsorbents, including polymeric hydrogel forming materials) and fibrous webs (36), to form a composite heterostructure (30). The composite absorbent heterostructures are useful, for example, in applications such as diapers, incontinence articles, hygienic supplies and other applications which require good fluid absorbency and retainment properties. The granular material can be made of light plastic materials such as polystyrene or materials such as sand or seeds, and the grains can be hollow, with possible access to their interior volumes.
