Abstract: A polymer fiber sheet exhibits high porosity and good tensile properties in both “wet” and “dry” states. A fiber modifying agent is incorporated into a polymer extrusion and fiber formation process to produce a highly porous polymer fiber sheet that is instantaneously wettable by an aqueous medium. The fiber modifying agent functions as either one or both (1) a plasticizer that reduces the polymer extrudate melt viscosity and allows the formation of fine fibers during processing and (2) a surface modifying agent that promotes the instantaneous and sustainable wettability of individual polymer fibers and a porous fiber sheet formed from them. The polymer fiber sheet maintains its wettability even after repeated washing and drying cycles. The resultant fiber sheet can be densified and embossed to provide a desired thickness and porosity, while at the same time longitudinal ribs with desired pattern can also be formed on the fiber sheet.

Abstract: The purpose of the present invention is to provide a method whereby deposits which have occurred on the surfaces of a fiber bundle during flameproofing treatment of a carbon fiber-precursor acrylic fiber bundle can be efficiently removed prior to carbonization treatment at high temperature. The method for production of carbon fiber bundle includes a step in which, after a carbon fiber-precursor acrylic fiber bundle has been heated and undergone flameproofing treatment, the fiber bundle is subjected to a plasma treatment involving contact with a plasma gas in gas phase, or to an ultraviolet treatment involving irradiation with ultraviolet in gas phase; and a step in which the fiber bundle having undergone the plasma treatment or the ultraviolet treatment is subjected to a carbonization treatment.
