Abstract
An absorbent core is provided including a substrate that performs at least one fluid handling function. At least a portion of at least one region of the substrate has been modified by aperturing, calendering, coating, creping, heating, printing, stretching, or a combination thereof to impart at least one different fluid handling function. The substrate is folded to provide a plurality of panels wherein at least a portion of one panel corresponds to at least a portion of the modified region of the substrate. An absorbent article including the absorbent core and a process for making the absorbent core are also disclosed.
Claims29
An absorbent core, comprising:
- a substrate which is folded upon itself to provide a plurality of panels, wherein the substrate is folded to provide an absorbent core having a cross-sectional configuration selected from the group consisting of an “e”-shape, a “z”-shape, a sigma-shape and an accordion-shape;
- the substrate performing a first fluid handling function;
- at least one portion of at least one panel performing a second fluid handling function different from the first fluid handling function;
- wherein the at least one portion of at least one panel further comprises a modifying material comprising a binding agent which is an absorbent adhesive composition of a crosslinkable binder composition;
- and
- the crosslinkable binder composition comprises an alkoxysilane grafted poly(ethylene oxide).
