Estimating the term…
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.
An absorbent materials system for personal care products having a separate body side liner layer, said absorbent materials system comprising at least a three-layered fibrous laminate fabric comprising natural fibers and further including at least one internal layer, which fabric distributes artificial menses according to a gush/distribution test as given herein, resulting in a ratio of at least about 0.06, wherein said fabric comprises fibers which individually distribute fluid poorly and transport fluid well as a fiber bundle, and further wherein said fabric has a penetration time of less than 40 seconds.
A laminate comprising a first fibrous layer having a first density between about 0.02 and 0.14 g/cc, a middle layer adjacent to and in liquid communication with said first layer and comprising oriented fiber surface materials, and a second fibrous layer adjacent to and in liquid communication with said middle layer and having a density greater than said first density, and said middle layer comprises oriented surface fibers which individually distribute fluid poorly and transport fluid well as a fiber bundle, wherein said middle layer distributes artificial menses according to a gush/distribution test as given herein resulting in a ratio of at least about 0.06, and further wherein at least one of said first and said second fibrous layers comprises natural fibers.
