  • Publication number: 20060162090
    Abstract: The present invention is directed to durable finishes for cellulose-containing fibers and fibrous substrates. The active components of the finishes are hydroxyl-containing amines, and preferably trialkanol amines. When combined with a suitable crosslinker, the amines become attached to and crosslinked on the substrate fiber, and form a soft resinous coating that is durable to cleaning procedures. This polymeric coating imparts durable anti-microbial activity and renewable control of certain odors.

  • Publication number: 20060021150
    Abstract: Compositions for imparting a performance enhancing property to a fabric comprising a complex between an anionic polymer and a cationic polymer, wherein either the anionic polymer or the cationic polymer comprises a functional group that is capable of imparting the performance enhancing property to the fabric are disclosed. The performance enhancing properties are durable and can withstand many home launderings. In addition, methods for applying polyelectrolytes complexes to fabrics to impart a persistent performance enhancing property to the fabric are disclosed. Fabrics having durable performance enhancing coatings are described, where the coatings are formed from polyelectrolytes.
