Abstract
The apparatus comprises a vessel to hold fiber to be dyed, the vessel being formed of a gas tight pressure resisting sealed construction and having a lid member to seal the vessel, the lid member being provided with a pressure control valve to control the internal pressure of the vessel, and the vessel being formed in cylindrical shape and being provided with a ring body integrally on its outer periphery; a flatcar for mounting the vessel which includes a pair of rotary shafts on an underframe, and the rotary shafts being rotatably connected to an output shaft of a geared motor by means of a chain, and the rotary shaft having a slip stop ring to position the rotary ring body of the vessel; and a microwave oscillating device having a radiation chamber connected to a microwave oscillator by means of a waveguide, and the internal pressure of the vessel being set at pressure above one atmosphere of pressure, and the microwaves are used to generate heat and the fiber is dyed by a boiling phenomenon at a boiling temperature above 100.degree. C.
