<p>A process for treating high-loft porous fabrics with topically applied active agent is provided and includes the steps of applying an active agent (16) to a surface (12A) of the fabric (12) and forcing the active agent (16) through the entirety of the web (12) by directing a focused stream (20) of air or steam, at a rate above 25 meters/second, into and through the web (12) and also applying a vacuum to the opposite side of the web (12) to collect the air, condensate and/or active agent (16) drawn out of the fabric (12). Fabrics having a thickness in excess of 50 mils with densities between 0.2 g/cc and 0.008 g/cc have a topically applied active agent substantially uniformly distributed throughout the entire fabric thickness.</p> |
