  • Process for making a fibrous structure comprising cellulosic and synthetic fibers
    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.
