  • Low density acrylic fiber
    Patent number: 6740722
    Abstract: An acrylic fiber having cotton-like properties with modified, internal void structure and optical characteristics, the acrylic fiber comprising a BYK Gardner Luster (BYL) reflectance measurement of less than about 44.
    Type: Grant
    Filed: September 25, 2001
    Date of Patent: May 25, 2004
    Assignee: Solutia Inc.
    Inventors: Gary J. Capone, Danny W. Carter, C. Wayne Emerson
  • Chitosan-containing acrylic fibers and process for preparing the same
    Patent number: 6551705
    Abstract: The present invention is directed to chitosan-containing acrylic fibers having a total chitosan content of 0.05 to 2% by weight and an extractable chitosan content of not less than 0.03% by weight to less than the total chitosan content. The antimicrobial activity of the chitosan-containing acrylic fibers of the present invention can persist for a long period of time and is not deteriorated even when subjected to posttreatments, such as dyeing and bleaching of fibers, and treatments in usual service environments of fiber products, such as washing and ironing.

  • Polyacrylonitrile polymer treatment
    Patent number: 6143835
    Abstract: The present invention relates to a method for exchanging derivatizing agents onto ionic functional groups, preferably sulfate, sulfonate, and carboxylate functional groups, in a polymer, and then thereby holding these derivatizing agents in place by strong ionic bonds. The ionic functional groups are those currently used in industry to enhance dyeability, and therefore do not present a problem with textile treatments normally encountered in the industry. Polyacrylonitrile polymer is synthesized with an ionic comonomer to obtain a number of dye sites above that required for dying. The sodium or other cation that is ionically bound to the ionic comonomer, as well as the sulfonate and sulfate end groups, is then exchanged with a derivatizing agent. The preferred derivatizing agents comprise a quaternary ammonium compound.

  • Fiber bundles including reversible crimp filaments having improved dyeability
    Patent number: 5458968
    Abstract: A bicomponent, reversible crimp filament useful in textile and fabrics applications is disclosed. The filament is characterized by a total shrinkage of between about 25 percent and about 50 percent, a fiber shrinkage of between about 2 percent and about 20 percent, a crimp shrinkage of about 20 percent and about 38 percent and a basic dye level of less than about -8.
