  • Method for modifying fibers
    Patent number: 7803196
    Abstract: A method for modifying fibers is provided, which method comprises suspending and dispersing in water under shear force a cellulose ether having such a low degree of substitution that a molar degree of substitution with an alkyl group and/or a hydroxyalkyl group ranges from 0.05 to 1.3, applying the resulting dispersion and a crosslinking agent or an aqueous resin emulsion to fibers, and thermally treating the applied fibers.
    Type: Grant
    Filed: June 29, 2005
    Date of Patent: September 28, 2010
    Assignees: Aichi Prefectural Government, Ichinomy Fashion Design Center Foundation, Shin-Etsu Chemical Co., Ltd.

  • Method for modifying fibers and modified fibers
    Publication number: 20060000027
    Abstract: A method for modifying fibers comprises steps of adding a crosslinking agent and/or an aqueous resin emulsion to an alkali aqueous solution dissolving therein a cellulose ether having such a low degree of substitution that a molar degree of substitution with an alkyl group and/or a hydroxyalkyl group ranges 0.05 to 1.3, applying the resulting solution to fibers, neutralizing the applied solution with an acid for coagulation, and thermally treating the fibers. Alternatively, the method comprises adding a crosslinking agent and/or an aqueous resin emulsion to an alkali aqueous solution dissolving therein a cellulose ether having such a low degree of substitution that a molar degree of substitution with an alkyl group and/or a hydroxyalkyl group ranges 0.05 to 1.3, applying the resulting solution to fibers, thermally treating the thus applied fibers, and applying an acid to the fibers to neutralize the alkali left on the fibers.
