Abstract
An absorbent article including an absorbent body capable of absorbing a liquid and a flow-modulating layer in liquid communication with the absorbent body. The flow-modulating layer is formed from hydrophilic meltblown fibers having an average diameter of from about 20 to about 60 microns. The flow-modulating layer has an average pore size of from about 90 to about 300 microns and a basis weight of from about 50 to about 600 grams per square meter. The average pore size of the absorbent body is less than the average pore size of the flow-modulating layer. The flow-modulating layer is capable of rapidly receiving multiple liquid insults and distributing the liquid in its X-Y plane prior to said liquid being absorbed by the absorbent body.
