  • Patent number: 7012033
    Abstract: Wash-durable fluorochemical-containing textile and/or fiber treatments that simultaneously impart soil resistance (or soil-release) properties and moisture wicking characteristics to target fabric substrates are provided. Such treatments surprisingly impart these two simultaneous effects to target fabrics and/or fibers because fluorochemicals generally provide moisture repellency rather than moisture wicking capabilities. As prior soil release/moisture wicking treatments do not function properly, or, alternatively, compromise hand or other properties of certain target textiles after treatment application, a new, effective, soil release/moisture wicking formulation for such purposes was needed. The inventive treatment is extremely durable on such fabric substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its soil release/moisture wicking properties.

  • Publication number: 20040121677
    Abstract: Textile fabric composed of synthetic fibers is subjected to a gas phase fluorination in a fluorine/inert gas atmosphere having a fluorine concentration in the range from 0.1 to 10% in order that the synthetic fiber surfaces may be activated in such a way that they are able to react with organic or inorganic compounds. Thereafter, the fabric is coated with a fluorocopolymer which is free of adhesion promoters. Similarly, yarn composed of synthetic fibers is first gas phase fluorinated and thereafter coated with a fluorocopolymer. Sewing yarn or thread, having been gas phase fluorinated, is bonded by means of a fluoropolymer coating. The improved adhesion makes the coated materials useful for a wide range of industrial applications. Textile fabric composed of synthetic fibers is subjected to a gas phase fluorination in a fluorine/inert gas atmosphere having a fluorine concentration in the range from 0.

  • Publication number: 20040116015
    Abstract: Wash-durable fluorochemical-containing textile and/or fiber treatments that simultaneously impart soil resistance (or soil-release) properties and moisture wicking characteristics to target fabric substrates are provided. Such treatments surprisingly impart these two simultaneous effects to target fabrics and/or fibers because fluorochemicals generally provide moisture repellency rather than moisture wicking capabilities. As prior soil release/moisture wicking treatments do not function properly, or, alternatively, compromise hand or other properties of certain target textiles after treatment application, a new, effective, soil release/moisture wicking formulation for such purposes was needed. The inventive treatment is extremely durable on such fabric substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its soil release/moisture wicking properties.

  • Patent number: 6638579
    Abstract: A paper machine substrate modified to resist contamination by adhesive materials. The paper machine substrate includes: a paper machine substrate; and an active agent that is grafted to the surface of the paper machine substrate to lower the surface energy of the paper machine substrate so that the substrate resists contamination by adhesive material. The papermachine substrate may be made by a process that includes the steps of: providing a paper machine substrate; applying an active agent to the paper machine substrate; and exposing the paper machine substrate to greater than about 2 million rads (Mrad) of radiation to cause a reaction between the active agent and the substrate so the active agent becomes joined to the substrate. The active agent may be a fluorinated monomer, a fluorinated polymer, a perfluorinated polymers, or a polyalkyl siloxane.
