摘要:
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 one embodiment, the chemical composition is extruded into fibers and applied to the paper web. The chemical composition can contain, for instance, various additives, such as a polysiloxane softener.
