Abstract
This invention is directed to an aqueous polymeric binder composition that is useful in improving the wet strength of pre-moistened wipes. The binder composition comprises a blend or mixture of two components. One component is a water dispersible polymer capable of binding together the fibers composing a nonwoven web. The other component is an aqueous solution or dispersion of a polymer comprised predominantly of self-crosslinking monomer(s).
