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.

[ What is claimed is:] [1.] A method of making a non-continuous absorbent composite having a length, width and thickness, said method comprising the steps of:1) providing a substantially continuous absorbent composite sheet having a thickness, length and a width and comprising an absorbent macrostructure comprising crosslinked interconnected absorbent gelling particles, and a substrate attached to the absorbent macrostructure;2) forming a plurality of slits penetrating at least partially through the thickness of the sheet, wherein the slits are oriented in the length direction; and3) stretching the slitted sheet in the width direction, thereby forming voids from the slits in the sheet.
