Abstract
A fluid management layer having an integrated, carded, nonwoven is described. The fluid management layer has a basis weight of between about 40 grams per square meter (gsm) and about 75 gsm; a plurality of absorbent fibers, a plurality of stiffening fibers and a plurality of resilient fibers; wherein the fluid management layer exhibits a total compression of greater than 0.40 mm and has a total recovery of at least 0.35 mm, and wherein the fluid management layer has a density of less than or equal to 0.08 g/cc.
