PURPOSE:To obtain the excellent cut surface of fibers by cutting a plurality of specified electric conductive fibers having been bundled into a specified length, using specified ethylene vinyl acetate copolymer as a binder for bundling. CONSTITUTION:A plurality of electrical conductive fibers or long fibers having specific resistance equal to 0.01OMEGA.cm or less and 5-20mum cross sectional diameter are dipped into the molten material made of the mixture of ethylene vinyl acetate copolymer and hydrocarbon family wax having 5-200kg/cm<2> tensile fracture strength, 10-100% tensile fracture elongation, the Izod valve equal to 2kg.cm/cm or more, rigidity 10kg/cm<2> and the viscosity equal to 1,000cps or less at 170 deg.C. Then, the electric conductive fibers having been obtained are cut into 2-10mm. length. Because a specified binder is used, even if the bundle of electric conductive fibers with high density of 1,000-20,000 fibers is produced, its cutting property is good. |
