Abstract
An anhydrous fiber-dyeing apparatus using vacuum transfer, includes: 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; and a vacuum means suctioning air through an inner space of the drum to form a vacuum pressure through the fine holes of the drum.
Claims17
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.
An anhydrous fiber dyeing method using vacuum transfer, comprising:
- (S1) winding a fiber on an outer surface of a drum;
- (S2) covering, with a dye-coated transfer film, an 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 to form vacuum pressure through fine holes of the drum,
- wherein in step (S2), after a carrier film is covered on the outer surface of the fiber, both end portions or the entirety of the transfer film are sealed against the drum with a sealing sheet.
An anhydrous dyeing fiber body using vacuum transfer in which the same color is transferred in a cross-sectional direction of the fiber and different colors are transferred in each section along a longitudinal direction of the fiber.
