Abstract:
A liquid management layer constructed from large diameter uncrimped fibers in the form of a spunbond nonwoven web is described. Embodiments of the liquid management layer can include a plurality of thermoplastic fibers in the form of a spunbond nonwoven web where the plurality of thermoplastic fibers are randomly oriented and uncrimped, where the liquid management layer has a maximum void volume of 25 cc/g and a web density of at least 0.05 g/cc, where the liquid management layer has a maximum thickness of 1.5 mm, a basis weight of at least 30 g/m2 and a rewet value of less than 0.4 g according to test method WSP 70.8, and where the liquid management layer has an average fiber diameter of at least 40 microns based on the number of thermoplastic fibers in the liquid management layer and where less than 10% by count of the plurality of thermoplastic fibers in the liquid management layer have an absolute fiber diameter less than 30 microns. Additional embodiments of the invention include a personal care absorbent article incorporating the liquid management layer over an absorbent core.
