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. In another embodiment, a unitary fibrous structure comprises a plurality of cellulosic fibers randomly distributed throughout the fibrous structure, and a plurality of synthetic fibers randomly distributed throughout the fibrous structure, wherein at least a portion of the plurality of synthetic fibers comprises co-joined fibers, which are co-joined with the synthetic fibers and / or with the cellulosic fibers.

A pleated filter is made from a monocomponent monolayer nonwoven web of continuous monocomponent meltspun partially crystalline and partially amorphous oriented fibers of the same polymeric composition that are bonded to form a coherent and handleable web having a Gurley Stiffness of at least 100 mg and which further may be softened while retaining orientation and fiber structure. Rows of pleats are formed in the nonwoven web, and the web is cut to a desired size and shape to provide a pleated filter element containing a self-supporting porous monocomponent monolayer matrix of fibers bonded to one another at least some points of fiber intersection and having an average initial submicron efficiency of at least 15% at a 1.52 meters / sec face velocity. The filter element is deformation resistant without requiring stiffening layers, bicomponent fibers, adhesive or other reinforcement in the filter media layer.

The present invention relates to absorbent tissue-towel paper products comprising one essentially continuous ply of fibrous structure having a first surface and a second surface, wherein the product has an HFS absorbency greater than 8 g / g and the first surface exhibits an embossment height of at least 650 μm and the second surface exhibits an embossment height of at least about 650 μm.

Fibrous structures and / or sanitary tissue products comprising such fibrous structures, wherein the fibrous structures comprise a design, particularly a surface design, and processes for making such fibrous structures and / or sanitary tissue products are provided.

A method for forming a nonwoven fibrous structure comprising a plurality of synthetic fibers. The method employs a hydrophilizing agent. The synthetic fibers may associate with one or more hydrophilizing agents.

A molded fibrous structure comprising a molded element. The molded element may be hollow. The molded elements may provide for an increase in the fluid uptake of the fibrous structure. The molded element may provide a texture impression of a high level molded fibrous structure.

A nonwoven fibrous structure comprises a plurality of synthetic fibers. The synthetic fibers may be associated with one or more hydrophilizing agents. A process for making the nonwoven fibrous structure involves association of the synthetic fibers with one or more hydrophilizing agents.
