Abstract
A non-continuous absorbent composite having a plurality of interconnected strands separated by voids. The strands comprise a porous, absorbent macrostructure and a substrate. 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 composite can absorb the liquids without undesirable planer expansion. The composite is useful in absorbent articles such as diapers, adult incontinence pads, and sanitary napkins are disclosed.
