ABSORBENT CORES AND METHODS OF MANUFACTURING
Document Type and Number:
WIPO Patent Application WO/2023/070240
Kind Code:
A1
Abstract:
Absorbent structures and methods of forming absorbent structures are disclosed. An absorbent structure may comprise a bodyside liner (28), an outer cover (26), and an absorbent structure. The absorbent structure may comprise a top material, a bottom material, a lofty nonwoven reinforcing material between the top material and the bottom material, and an absorbent layer of superabsorbent particles (318) and adhesive filaments (316) between the top material and the lofty nonwoven. The superabsorbent particles (318) may be present at greater than 90% by weight of absorbent material, and the adhesive filaments (316) may form a three-dimensional mesh network comprising network adhesive filaments (316) with the superabsorbent particles (318) immobilized within the mesh network, the network adhesive filaments (316) and superabsorbent particles (318) extending throughout a three-dimensional space defined by the network adhesive filaments (316) and the superabsorbent particles (318), with the network adhesive filaments (316) extending in random orientations throughout the three-dimensional space.
