  • 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.

  • Patent number: 6884842
    Abstract: Synthetic polymer complements (SPCs) are provided, as well as methods for their synthesis and use. The SPCs may have surfaces that include functional groups that are complementary to surface sites of targets such as nanostructures or macromolecular targets, and may be capable of specifically interacting with such targets. The positions of the functional groups in one embodiment are stabilized by a polymer network. The SPCs are formed by contacting the target with a set of monomers which self-assemble on the target, and then are polymerized into a network to form the synthetic polymer complement. At least a portion of the surface of the resulting SPC thus may include an imprint of the target. The complex of the SPC and the target may be the desired product. Alternatively, the target is released, for example, by controllably expanding and contracting the crosslinked network. The SPC is isolated and used in many applications.

  • Patent number: 6872424
    Abstract: The present invention relates to textile treatment compositions for imparting desirable characteristics durably to textile fibers and fabrics, including softness, hydrophobicity, oleophobicity, surface lubricity, abrasion resistance, tear resistance, improved drape, and pilling resistance. More particularly, in one embodiment, the invention is directed to preparations that comprise a carboxylate-functionalized fluorinated polymer and a catalyst that is capable of forming reactive anhydride rings between carboxyl groups on the polymer. In another embodiment, the invention is directed to preparations comprising a polymeric softener having at least one anhydride functional group or at least one reactive group capable of forming an anhydride functional group, together with a catalyst for forming anhydrides from the reactive group or groups. In either embodiment, the resulting reactive anhydride rings bind to substrates, such as textiles and other webs, having free sulfhydryl, alcohol, or amine groups.

  • Patent number: 6855772
    Abstract: The present invention is directed to polymeric treatment preparations for textiles and other fibrous substrates that impart water and oil repellency to fibers, yarns, textiles, or other fibrous substrates. More particularly, this invention comprises an aqueous solution, emulsion or suspension of (a) a fluorinated polymer that contains reactive groups that can complex with metal atoms that have a formal charge of 2 or greater, and (b) one or more metal atoms that have a formal charge of 2 or greater. The invention is further directed to the process for treating fibrous substrates with textile preparations in one step that provide water/soil repellency that is durable to repeated cleanings and to abrasion. This invention is further directed to the yarns, fibers, fabrics, textiles, webs, finished goods, or nonwovens (encompassed herein under the terms “textiles” and “fibrous substrates”) treated with the textile-reactive water- and soil-resistant preparation of the invention.
