  • SPUN YARN AND INTERMEDIATE FOR FIBER-REINFORCED RESIN, AND MOLDED ARTICLE OF FIBER-REINFORCED RESIN USING THE SAME
    Publication number: 20120220179
    Abstract: Disclosed is a spun yarn for a fiber-reinforced plastic, which is composed of blended yarns (3a, 3b) of a natural plant fiber and a synthetic fiber. The synthetic fiber is a thermoplastic synthetic fiber capable of serving as a matrix resin in a FRP. Also disclosed is an intermediate for a fiber-reinforced plastic that is a woven fabric, a knitted fabric, a multiaxial warp knitted fabric or a braided fabric, formed of the aforementioned spun yarn for a fiber-reinforced plastic. Also disclosed is a fiber-reinforced plastic molded article that is obtained by heating and press-molding the intermediate for a fiber-reinforced plastic at a mold temperature equal to or higher than the melting point of the synthetic fiber, or by aligning the spun yarn for a fiber-reinforced plastic in at least one direction, heating and press-molding the same at a mold temperature equal to or higher than the melting point of the synthetic fiber.

  • Animal fiber superior in shrink proofing and method for preparation thereof
    Patent number: 6969409
    Abstract: The present invention provides an animal fibers having improved shrink proofing and pilling resistance properties and method for preparation thereof. An animal fiber having excellent shrink proofing and pilling resistance and retaining its original water repellency is also provided. A method of treating animal fiber in which a surface layer part of animal fiber is primary-oxidized in advance with an oxidizer, and aqueous treatment liquid containing ozone in the form of ultrafine bubbles of 5? or less is allowed to collide against the fiber by blowing the liquid on the fiber in the aqueous treatment solution, and then, the fiber is treated with a reducing agent. Particularly, the above-mentioned method for treating animal fiber in which ultrafine bubbles of ozone are formed by using a line mixer. The method in which an apparatus which collects the ultrafine ozone bubbles in aqueous treatment liquid on the fiber is used so that the bubbles are not scattered out of a treatment reaction bowl.
