  • Publication number: 20200040520
    Abstract: In one embodiment, the present invention relates to silicone-fixed fibers including fibers and silicone fixed to the fibers. The silicone includes an acrylic-modified organopolysiloxane (A) having two or more acrylic groups per molecule. A rate of decrease in the amount of Si after the silicone-fixed fibers are washed 10 times is less than 50%. The present invention relates to a method for producing silicone-fixed fibers. The method includes coating or impregnating the fibers with a fiber treatment agent containing silicone, and irradiating the fibers coated or impregnated with the fiber treatment agent with an electron beam so that the silicone is fixed to the fibers. The silicone includes an acrylic-modified organopolysiloxane (A) having two or more acrylic groups per molecule. Thus, the present invention provides silicone-fixed fibers that include fibers to which silicone is fixed by electron beam irradiation and have a good texture even after washing, and a method for producing the silicone-fixed fibers.

  • Patent number: 8357208
    Abstract: Disclosed is a method for producing a modified animal fiber, the method includes step 1 (31, 32) of pre-oxidizing a cystine bond (—S—S— bond) present in an epidermal cell of an animal fiber to bring the cystine bond into a low oxidation state, step 2 (33) of oxidizing with ozone the pre-oxidized —S—S— bond to bring the —S—S— bond into at least one high oxidation state selected from di-, tri-, and tetra-oxidation states, and step 3 (34) of reductively cleaving the —S—S— bond in a high oxidation state. The method imparts shrink resistance and pilling resistance to an animal fiber. In the step 2 (33) ozone is microdispersed in an aqueous solution comprising an anionic surfactant having a C8-24 alkyl group, and the animal fiber is contacted with the ozone.
