    • A pressure steam treatment apparatus (1) according to the invention includes a pressure steam treatment chamber (10) and labyrinth sealing chambers (20) . The labyrinth sealing chambers (31, 33) are respectively arranged on a fiber bundle inlet and on a fiber bundle outlet of the steam treatment apparatus (1), having a running path of the fiber bundle in a horizontal direction and having plural labyrinth nozzles (24) on top and bottom of the running path. The difference (ΔH) between a maximum value and a minimum value of the distance in the perpendicular direction of the top and bottom side labyrinth nozzles (24), of a pair of opposing labyrinth nozzles (24) 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 necessary due to the leakage of pressure steam can be reduced, the deformation of the apparatus is prevented, and also, the raise of fuzz on the fiber bundle and fiber bundle breakage can be prevented at the same time.

    • Disclosed are liquid crystal polyester fibers, which have a peak half-width of 15°C or greater at an endothermic peak (Tm1) observed by differential calorimetry under a temperature elevation of 20°C/minute from 50°C, polystyrene equivalent weight average molecular weight of 250,000 or more and 2,000,000 or less, and a variable waveform of less than 10% in terms of the half inert diagram mass waveform determined by a Uster yarn irregularity tester. Also disclosed is a method for producing liquid crystal polyester fibers, wherein liquid crystal polyester fibers are formed into a package, the fibers are then subjected to solid-phase polymerization, and the solid-phase polymerized liquid crystal polyester fibers are unrolled from the package and successively heat treated without being once taken up. The heat treatment temperature is controlled at a temperature of the endothermic peak temperature (Tm1) of the solid-phase polymerized liquid crystal polyester fibers + 60°C or higher, and the speeds of the fibers before and after heat treatment are regulated, respectively, by first and second rollers.
