Abstract
A personal care absorbent article made of a nonwoven material having a plurality of polymeric fibers having a fiber interior comprising at least one of a liquid fluid and a gaseous fluid. The nonwoven materials are produced by heating at least one polymer to a melting point, forming a molten polymer; extruding the molten polymer through a plurality of capillaries, injecting a liquid fluid and/or a gaseous fluid into the molten polymer prior to, during and/or after the extruding step, forming a plurality of fluid-filled polymeric fibers, wherein the liquid fluid and/or gaseous fluid is dispersed within the interior of the polymeric fibers, and depositing the fluid-filled polymeric fibers onto a web forming surface, forming a nonwoven material.
