<p>The present invention relates to a centrifugal spinning apparatus having nozzle tubes in which the length of the end part thereof on the opposite side to the rotational direction of the shaft is longer than the length of the end part thereof on the side of the rotational direction of the shaft, thereby attaining extra-fineness of the fiber and raising the diameter uniformity thereof. To that end, a centrifugal spinning apparatus for producing fiber according to the present invention comprises a centrifugal rotating body for spinning, through spinning nozzles, a spinning solution in an accommodating space in the interior of centrifugal rotating body by means of the centrifugal force generated by the rotation of the shaft, each spinning nozzle comprising: a nozzle hole in communication with the accommodating space and the outer surface of the centrifugal rotating body; and a nozzle tube in communication with the nozzle hole and extending to the outside, wherein the length of the end part of the nozzle tube on the opposite side to the rotational direction of the shaft is longer than the the length of the end part on the side of the rotational direction of the shaft.</p> |
