Abstract
A non-continuous absorbent core having a plurality of interconnected strands separated by voids. The strands comprise a porous absorbent macrostructure. The porous macrostructure has interconnected absorbent gelling particles that are surface crosslinked with cationic, preferably polymeric, amino-epichlorohydrin adducts. Upon contacting liquids such as water or body exudates (e.g., urine), the absorbent core can absorb the liquids without undesirable planer expansion. The core is useful in absorbent articles such as diapers, adult incontinence pads, and sanitary napkins are disclosed.
