    摘要： A polymer substrate for radiation-induced graft polymerization in the form of a woven or non-woven fabric that comprises a woven or non-woven fabric composed of polymer fiber and a reinforcement polymer having a greater strength and a slower rate of radiation-induced graft polymerization than said polymer fiber. Also, radiation graft treated stock prepared from said polymer substrate. In another aspect, a radiation graft treated material in the form of a woven or non-woven fabric material that is composed of polymer monofilament fiber of which only the surface has undergone a radiation-induced graft polymerization but of which the center remains unaffected by grafting. In addition, a method for performing radiation-induced graft polymerization on substrates in the form of webs of woven or non-woven fabric, which comprises the steps of exposing a substrate woven or non-woven fabric composed of polymer fiber to electron beams in a nitrogen atmosphere, contacting the irradiated substrate with a specified amount of monomer in a nitrogen atmosphere, and subjecting the monomer and the substrate in mutual contact to graft polymerization in a nitrogen atmosphere, characterized in that the first through third steps are performed in succession.

    摘要： 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.

    摘要： Electrically regenerable desalting apparatus having the desalting compartment packed with ion exchangers produced by utilizing radiation-initiated graft polymerization, in which said ion exchangers are nonwoven fabrics in the form of a fiber assembly and a cation exchanger and an anion exchanger are disposed in a face-to-face relationship, with a porous material being interposed between the two ion exchangers. Having the ability to reject ions from liquids, the apparatus is particularly suited to the production of pure water in the electrical power generating industries (including the nuclear industry), electronic industry and the pharmaceuticals manufacturing industry, as well as to the desalting of thick fluids encountered in food and chemical manufacturing processes.
