发明名称 THIN ABSORBENT CORE MADE FROM FOLDED ABSORBENT LAMINATE
摘要 A disposable absorbent garment (10) comprising a topsheet (30), abacksheet (32), and an absorbent core (342) disposed between the topsheet and the backsheet. The absorbent core is forme d from a folded laminate comprising three layers, including an upper layer (342b), a lower layer (342c) and a central fibrous layer (342a) including from about 50 to about 95 percent by weight superabsorbent polymer and about 5 to about 50 percent by weight stabilizing additives. The upper and lower layers comprise tissue, airlaid fluff pulp or synthetic non-woven fibrous layers. T he central fibrous layer is adhesively bonded to both the upper and lower layers, all layers together assisting to maintain the dry an d wet integrity of the absorbent core. Folding of the thin absorbent laminate provides an absorbent core that can handle large doses of urine. The folded structure provides a central channel (360) that provides free volume (371) for temporary liquid storage, isolatio n and containment of bowel movements, and increases the surface area of laminate available for liquid absorption.
