Abstract

A unitary fibrous structure (100) comprises a plurality of cellulosic fibers (110) randomly distributed throughout the fibrous structure, and a plurality of synthetic fibers (120) 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 (100) comprising a plurality of cellulosic fibers (110) randomly distributed throughout the fibrous web (100) and a plurality of synthetic fibers (120) randomly distributed throughout the fibrous web (100) and causing redistribution of at least a portion of the synthetic fibers (120) in the embryonic web (100) to form the unitary fibrous structure in which a substantial portion of the plurality of synthetic fibers (120) is distributed throughout the fibrous structure in a non-random repeating pattern.
