Articles, such as sanitary tissue products, including fibrous structures, and more particularly articles including fibrous structures having a plurality of fibrous elements wherein the article exhibits differential cellulose content throughout the thickness of the article and methods for making same are provided.

A water-soluble film comprising a mixture of a polyvinyl alcohol (PVOH) resin, a plasticizer, and a metal salt, wherein the metal salt is present in the water-soluble film in an amount sufficient to reduce the enthalpy of melting of the film by at least 20% compared to the enthalpy of melting of an otherwise identical film not comprising the metal salt.

Methods of treating fibers comprising a polymer including at least one of a vinyl acetate moiety or a vinyl alcohol moiety, and resulting fibers or the products comprising the resulting fibers are disclosed. In an example embodiment, a fiber having a surface region and an interior region, includes a polymer comprising at least one of a vinyl acetate moiety or a vinyl alcohol moiety chemically modified with a modification agent. The fiber has a transverse cross-section including the interior region comprising the polymer having a first degree of modification and the surface region comprising the polymer having a second degree of modification greater than the first degree of modification.
