  • Patent number: 7918951
    Abstract: A method for making a unitary fibrous structure including the steps of providing a first plurality of synthetic fibers onto a forming member having a pattern of channels. The synthetic fibers are provided such that at least some of the synthetic fibers are disposed in the channels. A second plurality of cellulosic fibers are provided onto the synthetic fibers such that the cellulosic fibers are disposed adjacent to the synthetic fibers to form a unitary fibrous structure including the synthetic fibers and the cellulosic fibers, wherein the resulting fibrous structure has micro-regions of differential basis weight.

  • Patent number: 7645359
    Abstract: A method for making a fibrous structure including a plurality of synthetic fibers disposed in a predetermined pattern and a plurality of cellulosic fibers generally randomly distributed throughout at least one layer of the fibrous structure. The method includes depositing an aqueous slurry including synthetic fibers and an aqueous slurry including cellulosic fibers onto a fluid-permeable forming member having a pattern of channels. The slurries are dewatered to form a fibrous web, wherein the at least some of the cellulosic fibers are randomly distributed throughout at least a portion of the fibrous web and a plurality of synthetic fibers are at least partially non-randomly distributed in the channels.

  • Publication number: 20060180287
    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.

  • Publication number: 20060175030
    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.
