Abstract: A method of treating a fiber includes admixing a fiber comprising a polymer comprising at least one of a vinyl acetate moiety or a vinyl alcohol moiety and having a degree of hydrolysis less than 100% with a hydrolysis agent solution to form a mixture so as to increase the degree of hydrolysis of at least a portion of the fiber.

Abstract: 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 method of treating fibers includes contacting a surface of a fiber comprising the polymer with a modification agent to chemically modify at least a portion of the polymer with the modification agent in a region of the fiber comprising at least the surface of the fiber to form a modified fiber.

Abstract: The disclosure provides a nonwoven web, said nonwoven web including a plurality of fibers including a blend of fiber forming materials, the blend of fiber forming materials including a first polyvinyl alcohol polymer. The blend of fiber forming materials further comprises a second polyvinyl alcohol polymer or does not include carboxymethyl cellulose, hydroxypropyl methylcellulose or starch. The nonwoven web can be water-dispersible, optionally water-soluble, and/or flushable. The disclosure further provides a pouch including a nonwoven web including a plurality of fibers according to the disclosure. In some embodiments, the water dispersible pouch can include a laminate comprising a water-soluble film and a nonwoven web of the disclosure.

Abstract: 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.
