1. A method for making a fibrous structure, the method comprising the steps of:

  • providing a mixture of synthetic fibers and short cellulosic fibers onto a forming member so as to form one or more layers including the mixture of synthetic fibers and short cellulosic fibers;

    providing a plurality of long cellulosic fibers onto the mixture of synthetic fibers and short cellulosic fibers so as to form one or more layers including predominantly long cellulosic fibers to form an embryonic web;

    forming a unitary fibrous structure including the one or more layers including the mixture of synthetic fibers and short cellulosic fibers and one or more layers including predominantly long cellulosic fibers from the embryonic web;

    transferring the unitary fibrous structure to a molding member comprising a pl fluid-permeable areas present in a pattern and a plurality of fluid-impermeable areas; and

    redistributing at least some of the synthetic fibers within the unitary fibrous structure by heating the synthetic fibers within the fluid-permeable areas of the molding member resulting in a pattern of micro-regions of synthetic fibers corresponding to the fluid-permeable areas of the molding member.
