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.
An absorbent structure having a three-dimensional shape, a fluid-receiving side and a non-receiving side, the non-receiving side occupying a first x-y plane, the fluid receiving side occupying a second x-y plane, a caliper measured along a z-direction relative the first and second x-y planes, 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 fluid-receiving side, each of the first zone and the second zone comprising a co-formed blend of constituents including AGM particles, the particles in the first zone having a first average particle size, and the particles in the second zone having a second average particle size, wherein the first average particle size is smaller than the second average particle size, and wherein the AGM particles in one or both the first and second zones are stratified so as to generally exhibit a gradient of particle sizes along the z-direction.
An absorbent structure having a three-dimensional shape, a fluid-receiving side and a non-receiving side, the non-receiving side occupying a first x-y plane, the fluid receiving side occupying a second x-y plane, a caliper measured along a z-direction relative the first and second x-y planes, 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 fluid-receiving side, each of the first zone and the second zone comprising a co-formed blend of constituents including meltblown filaments, the meltblown filaments in the first zone having a first average filament size, and the meltblown filaments in the second zone having a second average filament size, wherein the first average filament size is smaller than the second average filament size.
