Abstract

A method is disclosed for topical application of compositions containing a chemical additive onto a paper web. The present invention is also directed to paper products formed from the method. In general, the method includes the steps of extruding a composition containing a chemical additive through a melt blown die and then applying the composition to a moving paper web. In particular, the method provides for the application of tacky compositions to a web through a melt blown die while avoiding die tip clogging. In one embodiment, the chemical composition is extruded into fibers and applied to the paper web. The chemical composition may contain, for instance, various additives, such as a polysiloxane softener and one or more beneficial agents.
