Abstract: An improved method for creating fibers from a material dissolved in a solvent. In one embodiment, the method includes the steps of feeding a fiber making material dissolved in a solvent through a die including at least two rows of nozzles to form fiber strands. An attenuation medium is provided about the fiber strands. The attenuation medium is provided in a direction that is generally parallel to the fiber strands such that the attenuation medium elongates the fiber strands. The attenuation medium has a relative solvent-vapor content of at least about 50 percent.

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.
