摘要： Provided is a pressure steam treatment apparatus of a fiber bundle and a producing method of a carbon fiber precursor fiber bundle which are suitable for producing a carbonated precursor fiber bundle which can suppress an influence of a leakage of a pressure steam to the outside of the apparatus so as to hold down a pressure steam supply amount to the minimum, simultaneously reduce a broken yarn, improve a yield ratio and have a high productivity. A pressure steam treatment apparatus (1) is provided with labyrinth sealing chambers (3) in back and forth of a pressure steam treatment chamber (2), and treats a plurality of fiber bundles traveling in parallel like a sheet along a fiber bundle travel path (5') in a lump under a pressure steam atmosphere. The fiber bundle travel path (5') of the labyrinth sealing chamber (3) is divided in parallel to the fiber bundle. Preferably, it is divided into a plurality of paths by a partition plate (3e).

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 65ˆ¼110% 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： This process for manufacturing a carbon-fiber precursor acrylic fiber bundle and this steam drawing apparatus are characterized in that the drawing of an acrylic fiber bundle with a pressured -steam drawing apparatus is conducted by: opening an acrylic fiber bundle by blowing a fluid thereto; supplying humidifying steam to the opened acrylic fiber bundle at a fiber temperature of 80 to 130°C to adjust the water content of the fiber bundle to 3 to 7%; and thereafter drawing the resulting acrylic fiber bundle in a pressurized-steam atmosphere. Thus, the present invention can prevent the breaking of a single fiber, the fluffing of the fiber bundle, and the breaking of the whole of the fiber bundle, though such defects are susceptible to occurring in a case where an acrylic fiber bundle is drawn by steam drawing at a high draw ratio, at a higher speed, or into a fiber having a small denier.
