AI Technical Summary
Technical Problem
Existing absorbent materials with superabsorbent polymers face issues with leakage due to gaps in the nonwoven fabric on the skin side, leading to potential spillage and discomfort.
Method used
The absorbent material incorporates a first nonwoven fabric with higher fiber density and embossed portions, along with a second nonwoven fabric and superabsorbent polymers bonded with adhesive, to create narrow gaps and prevent leakage.
Benefits of technology
The design effectively suppresses superabsorbent polymer leakage, maintaining absorbency and preventing tearing of the absorbent article's backing sheet, thereby reducing discomfort and fluid leakage.

Abstract
The present invention provides an absorbent material that incorporates a superabsorbent polymer and is capable of preventing the superabsorbent polymer from spilling out. [Solution] The absorbent body 4 comprises a first nonwoven fabric 41, a second nonwoven fabric 42 positioned on the non-skin side of the first nonwoven fabric 41, and a first superabsorbent polymer 40a positioned between the first nonwoven fabric 41 and the second nonwoven fabric 42. The fiber density of the constituent fibers of the first nonwoven fabric 41 is higher than the fiber density of the constituent fibers of the second nonwoven fabric 42. The constituent fibers of the first nonwoven fabric 41 are joined together by a plurality of embossed portions.
