Abstract
There is provided a fluid management material for personal care products which distributes artificial menses according to the gush/distribution test taught herein such that it has a distribution ratio of at least about 0.06. Its preferred that the fluid management material be part of an absorbent materials system having a first fibrous layer, a middle layer adjacent the first layer having hydrophilic oriented surface fibers, and a second fibrous layer adjacent the middle layer. In a personal care product configuration the oriented surface fibers result in a distribution ratio of at least 0.06 where the distribution ratio is a ratio of average of the mass of two end zones of a product divided by the mass of the center zone.
