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.
