Abstract
A disposable absorbent garment having a topsheet, a backsheet and an absorbent core located between the topsheet and backsheet. The absorbent core is formed from a folded laminate having an upper layer, a lower layer and a central fibrous layer that are bonded together and together assist to maintain the dry and wet integrity of the core. The fibrous layer includes about 50 to 95 percent by weight superabsorbent polymer and about 5 to 50 percent by weight stabilization additives. The upper and lower layers may be tissue, airlaid fluff pulp or synthetic non-woven fibrous layers. Folding the thin absorbent laminate provides an absorbent core that can handle large doses of urine, by providing a central channel having a free volume for temporary liquid storage and increasing the surface area of the laminate available for liquid absorption. The garment thus formed is thin, lightweight and economical.
