Inorganic Nongaseous Chemical Reactant Patents (Class 8/115.68)
  • Patent number: 11905648
    Abstract: A metalized fabric and method for metallization of fabric. The fabric is formed using two threads with different affinities for metallization, but which threads are not metalized prior to forming into the fabric. The threads will typically be woven using an unbalanced weave to provide one side of the fabric with a resultant greater amount of metallization than the other but this is not required. Once the resultant fabric is metalized, it will typically be more suitable for consistent color dying than fabric which was formed from both metalized and unmetallized threads.

  • Patent number: 8986594
    Abstract: The present invention relates to metal coated nano-fibres obtained by a process that includes electrospinning and to the use of said metal coated nano-fibres. The process is characterised in that a polymer nano-fibre with functional groups providing the binding ability to a reducing reagent is prepared by electrospinning at ambient conditions. Then this is contacted with a reducing agent, thereby opening the epoxy ring on the surface of polymer nano-fibre and replacing with the reducing agent and the reducing agent modified film is reacted with metal solution in alkaline media. Finally the electrospun mat is treated with water to open the epoxy rings in the structure and crosslinking the chains to provide integrity.

  • Publication number: 20090178206
    Abstract: The invention is an improved process for stripping chemically bonded spinning solvent from a solution-spun nonwoven web by adding antioxidant to the fiber-forming polymer, and transporting the nonwoven web through a solvent stripping zone at a temperature and for a time sufficient to reduce the solvent concentration of the fibers to less than about 1000 ppmw.

  • Patent number: 7276085
    Abstract: Methods of enhancing stain resistance of fibers, carpet yarns and carpets are disclosed. In one aspect, the invention relates to a method of treating fiber, yarn or carpet comprising applying an aqueous treating composition to fiber, yarn or carpet, wherein the aqueous treating composition comprises tannic acid heating the fiber, yarn or carpet to a temperature of at least about 160° F.; applying a second topical treating composition to the fiber, carpet or yarn, wherein the second aqueous treating composition comprises a fluorochemical; and heating the fiber, yarn or carpet to a temperature of at least about 160° F.

  • Patent number: 6863697
    Abstract: In a preferred embodiment, the present process involves subjecting a fabric having splittable conjugate yarns both to an acidic treatment and to a basic treatment, each of which erodes a portion of the components of the conjugate yarns. The acid treatment, given certain reaction kinetics, removes a portion of the polyamide element of the conjugate filament. The basic treatment has a similar effect on the polyester element of the conjugate filament, making it more hydrophilic. The at least partial removal of the polyamide component, coupled with the increased hydrophilicity of the polyester component, results in a fabric having enhanced absorptive properties. In an alternate embodiment, treatments with only acid or only basic solution may be employed.

  • Patent number: 6736856
    Abstract: The invention provides a production method capable of reducing the amount of the chemical liquid (hydrazine and sodium carbonate, etc.) for applying a crosslinking treatment and a hydrolytic treatment, capable of shortening the treatment time, and capable of obtaining crosslinked acrylic moisture absorbing fibers having a sufficient moisture absorbing-moisture releasing performance and provides crosslinked acrylic moisture absorbing fibers. In the case of producing the crosslinked acrylic moisture absorbing fibers by applying a crosslinking treatment and a hydrolytic treatment to acrylic fibers, acrylic fibers made of a copolymer containing from 1 to 5% by weight a comonomer having an acidic group as a comonomer component are used as the raw material fibers to be treated.
