    Abstract: Separation functional fibers are produced by exposing fibers with a core/sheath structure to an ionizing radiation and then grafting a polymerizable monomer to the fibers. Ion-exchange fibers are produced by introducing, through radiation-initiated graft polymerization, ion-exchange groups into the sheath of each of composite fibers the core and the sheath of which are composed of different kinds of high-polymer components. The separation functional fibers and the ion-exchange fibers are useful in various applications such as the production of pure water in electric power, nuclear, electronic and pharmaceutical industries and the demineralization of high-salt content solutions in the production of foods and chemicals. The fibers are also useful in removing harmful components from gases, as well as odorous components such as ammonia.

    Abstract: A photosensitive resin removing method is capable of completely removing a photosensitive resin employed as a photoresist in an etching process for etching an aluminum film, and its derivatives and of improving the durability of a photosensitive resin removing apparatus for carrying out the method. A mixed gas is produced by mixing fluorine compound gas and steam, the mixed gas is excited with microwaves, and the photosensitive resin is exposed to the excited mixed gas to gasify the photosensitive resin.
