Abstract
A cellulosic fibrous structure having two regions distinguished from one another by basis weight. The first region is an essentially continuous high basis weight network. The second region comprises a plurality of discrete low basis weight regions. The cellulosic fibers forming the plurality of second regions are generally radially oriented within each region. The cellulosic fibrous structure may be formed by a forming belt having zones of different flow resistances arranged in a particular ratio of flow resistances. The zones of different flow resistances provide for selectively draining a liquid carrier through the different zones of the belt in a radial flow pattern.
