The present invention relates to the selection of materials which are particularly useful as fluid distribution material for being used in disposable absorbent articles by being characterized in that they have a wicking time of less than 120 seconds and a cumulative flux of more than 0.075 grams/cm2/second for said preferential fluid distribution direction at 12.4 cm height, when applying the Vertical Wicking Test. A further useful selection criteria for such materials is a non-isotropic fluid distribution behavior, expressed in that the wicking time in the preferential distribution direction is less than 80% of the wicking time of perpendicular direction at 8.3 cm height, when applying the same test.

[ What is claimed is:] [1.]1. A fluid distribution material having one preferential fluid distribution direction wherein said material has a wicking time of less than 120 seconds and a cumulative flux of more than 0.075 g/cm2/sec for said preferential fluid distribution direction at a 12.4 cm vertic

[ What is claimed is:] [1.]1. A fluid distribution material having one preferential fluid distribution direction wherein said material has a wicking time of less than 120 seconds and a cumulative flux of more than 0.075 g/cm2/sec for said preferential fluid distribution direction at a 12.4 cm vertical wicking distance and wherein said material is mechanically treated by feeding the starting material through an incremental cross-directional web stretching system employing opposed pressure applicators having three dimensional surfaces which at least to a degree are complementary to one another.
