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.
