Abstract

A method for making fibrous webs with improved strength by adding agglomerated polyvinyl alcohol resin in the wet-end of a papermaking process. The agglomerated polyvinyl alcohol resin is readily retained in the paper during the formation of the web, providing for paper with improved strength properties.
