ABSTRACT:
A process for making a unitary fibrous structure comprises steps of: providing a 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 co-joining of at least a portion of the synthetic fibers with the cellulosic fibers and the synthetic fibers, wherein the co-joining occurs in areas having a non-random and repeating pattern. 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. In another embodiment, a unitary fibrous structure comprises a plurality of cellulosic fibers randomly distributed throughout the fibrous structure, and a plurality of synthetic fibers randomly distributed throughout the fibrous structure, wherein at least a portion of the plurality of synthetic fibers comprises co-joined fibers, which are co-joined with the synthetic fibers and/or with the cellulosic fibers.
