ABSTRACT:
An absorbent composite having 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 porous absorbent macrostructure can swell and imbibe the liquids. The composite is useful in absorbent articles such as diapers, adult incontinence pads, and sanitary napkins are disclosed.
