摘要： A steam-drawing apparatus has supply roll 1 that transfers carbon-fiber-precursor acrylic fiber bundle (T) in a transfer direction of fiber bundle (T); fiber-opening device 2 for opening fiber bundle (T); width control device 3 for controlling the width of fiber bundle (T); steam box 4 to provide steam for heating fiber bundle (T) to a temperature that allows fiber bundle (T) to be drawn; and haul-off roll 5 that transfers fiber bundle (T) at a speed faster than that of supply roll 1. Using width control device 3 provided at a position between supply roll 1 and steam box 4, the width of fiber bundle (T) after passing through width control device 3 is set to be 65˜110% of the width of fiber bundle (T) before entering the supply roll. The present invention proposes a method for producing a carbon-fiber-precursor acrylic fiber bundle using such a steam-drawing apparatus capable of conducting a high-speed drawing process of carbon-fiber-precursor acrylic fiber bundles at a high draw rate with stable results.

摘要： A pressure steam treatment apparatus according to the invention includes a pressure steam treatment chamber and labyrinth sealing chambers. The labyrinth sealing chambers are respectively arranged on a fiber bundle inlet and on a fiber bundle outlet of the steam treatment apparatus, having a running path of the fiber bundle in a horizontal direction and having plural labyrinth nozzles on top and bottom of the running path. The difference between a maximum value and a minimum value of the distance in the perpendicular direction of the top and bottom side labyrinth nozzles, of a pair of opposing labyrinth nozzles is 0.5 mm or smaller when the ambient temperature of the labyrinth sealing chamber is 140° C. This structure ensures that the energy cost can be reduced, the deformation of the apparatus and also, the raise of fuzz on the fiber bundle and fiber bundle breakage can be prevented at the same time.
