ABSTRACT: A body conformance system (22) includes at least one liquid-permeable, flexible containment layer (24), and an operative quantity of substantially free-flowing particulate material (28) constrained by the flexible containment layer (24). In a particular aspect, the substantially free-flowing particulate material (28) can exhibit a selected avalanche-time between avalanches. In another aspect, the particulate material can exhibit a selected, minimum retention capacity. In a further aspect, the system can exhibit a distinctive gap-protrusion area (104). In yet another aspect, the containment layer (24) can include a material that has a relatively high permeability to liquid, but a relatively high resistance to a passage of the particulate material.

ABSTRACT: A method for forming a composite absorbent member is provided that includes:
· · a) extruding a first fibrous component through a first meltblowing die and intermingling pulp fibers with the first fibrous component to form a first admixture;
· b) extruding a second fibrous component through a second meltblowing die and intermingling pulp fibers with the second fibrous component to form a second admixture; and
· c) codepositing the first and second admixtures on a collecting surface so as to form a composite structure having at least a first layer and a second layer. The second layer has a higher weight percentage of pulp fibers than the first layer, and the average diameter of the pores within the second layer is smaller than the average diameter of the pores within the first layer.

ABSTRACT: A composite absorbent member containing layers that have a controlled pore size distribution is provided. For example, in some embodiments, the composite absorbent member has an inner layer and two outer layers, in which the inner layer has a higher weight percentage of pulp fibers than the outer layers and also contains smaller pores than the outer layers. In this embodiment, the resulting composite member can have a fast intake rate, less leakage, reduced rewetting, and reduced bunching and twisting.
