ANHYDROUS FIBER-DYEING APPARATUS AND METHOD USING VACUUM TRANSFER, AND FIBER MANUFACTURED BY DYEING METHOD

Provided is an anhydrous fiber-dyeing apparatus and method using vacuum transfer, and a fiber manufactured by the dyeing method, the method winding a fiber around a drum on which a plurality of fine holes are formed, covering same with a transfer film coated with a dye of the color to be dyed, and then applying a high temperature in a vacuum chamber and, simultaneously, applying vacuum pressure in the drum so as to transfer the dye, having been coated on the transfer film, to the fiber, and dye same. The anhydrous fiber-dyeing method using vacuum transfer, according to the present invention, comprises the steps of: (S1) winding a fiber on the outer surface of a drum; (S2) covering, with a dye-coated transfer film, the outer surface of the fiber wound around the drum; (S3) heating the fiber by applying heat in a state in which the fiber and the transfer film are loaded on the drum; and (S4) suctioning air through the inner space of the drum, thereby forming vacuum pressure through the fine holes of the drum.
