    Abstract: Absorbent structures and methods of forming absorbent structures are disclosed. An absorbent structure may comprise a body side 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.

    Abstract: Absorbent structures and methods of manufacture are disclosed. In one embodiment, an absorbent structure may comprise a first layer, a second layer, and a mixture of particles and adhesive between the first layer and the second layer, wherein the particles are disposed at greater than 400 gsm and less than 600 gsm, wherein the adhesive is disposed at greater than 4% and less than 6%, by weight, of the weight of the particles, wherein the adhesive forms a three-dimensional mesh network comprising network adhesive filaments with the particles immobilized within the mesh network, and the network adhesive filaments extending substantially throughout a three-dimensional space defined by the network adhesive filaments and the particles, the structure having a Gray Level % Coefficient of Variability value (GL % COV) of less than or equal to 34.5, according to the Pad Uniformity Test Method.
