1. An anhydrous fiber-dyeing apparatus using vacuum transfer, comprising:
a hollow drum in which a plurality of fine holes are formed to penetrate therethrough, and a fiber to be dyed are wound around an outer surface thereof;
a transfer film covering the outer surface of the fiber wound around the drum and having an inner side surface coated with a dye;
heating means heating the fiber wound around the drum;
a vacuum means suctioning air through an inner space of the drum to form a vacuum pressure through the fine holes of the drum; and
a sealing sheet sealing both end portions or the entirety of the transfer film to the drum in a state in which the transfer film is covered on the outer surface of the fiber.
