Abstract
The present invention is directed to an absorbent material and the fibers therein, having two or more layers including an upper surface layer which has on the outer surface of the layer one or more surface area zones which are more wettable zones and adjacent thereto one or more less wettable zones, where the more wettable zones have a greater hydrophilicity than the less wettable zone. The present invention is also directed to the fibers therein, which contain polyvalent cation-containing compounds and fatty acid containing compounds. The present invention also provides for methods of treating fibers or solid materials and processes of producing the hydrophobic materials.
