  • Publication number: 20220133555
    Abstract: An absorbent structure is disclosed, which may be or form part of an absorbent core of an absorbent article. The structure has a caliper, a fluid-receiving side and a non-receiving side. The non-receiving side occupies a first x-y plane; the receiving side occupies a second x-y plane. The structure has a first zone constituting a first portion of the caliper proximate the non-receiving side, and a second zone constituting a second portion of the caliper proximate the receiving side. Each of the zones includes a co-formed blend of constituents. The blend may include AGM particles, spun filaments and/or cellulose fibers. In examples including AGM particles, particles in the first zone may have an average particle size smaller than that of particles in the second zone. In examples including filaments, filaments in the first zone may have an average filament size smaller than that of the filaments in the second zone.
