| description | PROBLEM TO BE SOLVED: To provide a method for doubling nano fibers, by which a yarn comprising the nano fibers produced by a charge induction spinning method and having a high strength and having uniform shape and dynamic physical properties can stably be produced. SOLUTION: This method for doubling the nano fibers includes supplying a core fiber 1 through a prescribed straight line route 2, flowing out a raw material solution from at least one small hole 3 rotated on the periphery of the straight line route 2, charging the flowed raw material solution with electricity, electrostatically exploding the charged raw material solution to produce the drawn nano fibers 7, rotating, synchronously with the small hole 3, an electrode 5 grounded or applied a voltage having a polarity opposite to the charge of the raw material solution by a high voltage-generating means 6 at a position on the side approximately opposite to the small hole 3 through the straight line route 2, collecting the produced nano fibers 7 with the electrode 5 to twine the nano fibers 7 around the core fiber 1, and thus producing and recovering the yarn 8 in which the nano fibers 7 are regularly wound on the core fiber 1.
