A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.

L'invention concerne la fabrication d'un composite absorbant qui comprend un premier tissu, un deuxième tissu, et des particules positionnées entre les deux tissus, et les articles absorbants fabriqués à partir de ce composite absorbant. Les particules selon l'invention sont fixées entre les deux tissus avec un adhésif, du thermoplastique ou une combinaison des deux. Les tissus sont liés ensemble de façon à limiter le déplacement des particules entre les tissus. La zone de liaison peut définir des poches ou d'autres formes. Dans les applications dans lesquelles la zone de liaison forme des poches, les particules peuvent être positionnées dans les poches. Les particules selon l'invention peuvent être des polymères superabsorbants (SAP) ou d'autres particules possédant des propriétés avantageuses.
