  • Uniformly treated fibrous webs and methods of making the same
    Publication number: 20030068947
    Abstract: A process for treating high-loft porous fabrics with topically applied active agents is provided and includes the steps of applying an active agent to a surface of the fabric and forcing the active agent through the entirety of the web by directing a focused stream of air or steam, at a rate above 25 meters/second, into and through the web and also applying a vacuum to the opposite side of the web to collect the air, condensate and/or active agent drawn out of the fabric. 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.

  • Flame inhibitor composition and method of application
    Patent number: 6153544
    Abstract: A flame retardant composition for treating a high pulp content nonwoven web is provided. The flame retardant composition includes soluble solids formed from inorganic salts, such as ammonium polyphosphate and sulfur. The TGA range of such soluble solids is from about 175.degree. C. to about 370.degree. C. The flame retardant composition may be continuously and uniformly applied to the high pulp content nonwoven web by a non-compressive process.
