ABSTRACT:
There is provided a surge material for personal care products which is a wettable web of fibers of 30 microns in diameter or less where the web has a permeability between about 250 and 1500 Darcys, a capillary tension between about 1.5 and 5 cm, and which maintains that permeability and capillary tension over the life of the web. Its preferred that the web have a density between about 0.02 g/cc to about 0.07 g/cc.
