Abstract: Functional agent-containing fibers according to an embodiment of the present invention, wherein a functional agent is supported by silicone fixed to the fibers. The silicone includes an acrylic-modified organopolysiloxane having two or more acrylic groups per molecule. A rate of decrease in the functional agent after the functional agent-containing fibers are washed 10 times is less than 40%. In the present invention, the functional agent-containing fibers may be produced, e.g., by irradiating fibers impregnated with a fiber treatment agent A containing silicone with an electron beam so that the silicone is fixed to the fibers, and impregnating the fibers to which the silicone has been fixed with a fiber treatment agent B containing a functional agent. The functional agent-containing fibers may be produced, e.g., by impregnating fibers with a fiber treatment agent C containing silicone and a functional agent and irradiating the fibers impregnated with the fiber treatment agent C with an electron beam so that the silicone is fixed to the fibers and the functional agent is supported by the silicone fixed to the fibers. Thus, functional agent-containing fibers having improved washing resistance and a method for producing the fibers are provided.

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.

Abstract: An addition curable silicone emulsion release composition suitable for forming a releasable film having a high releasability to a pressure sensitive adhesives simultaneously with good adhesion to a plastic film substrate is provided. A release film prepared by coating and curing such composition on a plastic film is also provided. The good adhesion and the high releasability to acryl pressure sensitive adhesives are realized despite the low content of the organopolysiloxane containing a large amount of trifunctional siloxane units and alkenyl groups which had been used for realizing the adhesion. The addition curable silicone emulsion release composition is prepared by blending predetermined proportion of mixtures of high molecular weight organopolysiloxanes each containing an alkenyl group and phenyl group at particular ratio.

Abstract: A silicone emulsion composition is provided comprising organopolysiloxane, organohydrogenpolysiloxane, surfactant, and water. Two organopolysiloxanes of different type are blended, whereby a cured silicone coating is improved to be fully adherent to plastic film and lightly peelable from pressure-sensitive adhesive. By limiting the SiH content of organohydrogenpolysiloxane, the composition is improved in shelf stability. A specific surfactant is used to control the size of emulsion particles so as to improve wettability to plastic film.
