Abstract
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; and 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.
