A process of forming improved cellulosic fibers, fibrous compositions containing cellulosic fibers, and absorbent articles comprising such compositions are disclosed. In the process, liquid ammonia penetrates cellulosic fibers in a pressurized environment, and when the pressure is released, an explosive process produces cellulosic fibers having unique structure and properties. The high pressure liquid ammonia treatment introduces a significant curl into the fiber and introduces a smooth, soft, silky feel to the fiber not present in conventional cellulosic fibers. Such fibers are particularly useful in tissue, wipes, distributive layers, fiber mats, filter papers, and other porous articles.
