ABSTRACT:
A unitary fibrous structure comprises a plurality of cellulosic fibers randomly distributed throughout the fibrous structure, and a plurality of synthetic fibers distributed throughout the fibrous structure in a non-random repeating pattern. A process for making the unitary fibrous structure comprises the steps of providing an embryonic fibrous web comprising a-plurality of cellulosic fibers randomly distributed throughout the fibrous web and a plurality of synthetic fibers randomly distributed throughout the fibrous web and causing redistribution of at least a portion of the synthetic fibers in the embryonic web to form the unitary fibrous structure in which a substantial portion of the plurality of synthetic fibers is distributed throughout the fibrous structure in a non-random repeating pattern.
