Abstract: Provided herein is a method for producing an acrylonitrile based fiber bundle by dry-jet wet spinning technique that serves to allow a high-grade, high-quality acrylonitrile based fiber bundle to be produced stably even if the traveling speed of the coagulated fibers is increased or the number of spinneret discharge holes is maximized in an attempt to enhance the production efficiency. The production method for an acrylonitrile based fiber bundle is characterized by first extruding a spinning dope solution through a plurality of discharge holes in a spinneret, then allowing the spinning dope solution to run downward into a coagulation bath liquid stored in a coagulation bath to form coagulated fibers, turning the coagulated fibers upward on a direction changing guide part located in the coagulation bath liquid below the spinneret, and pulling them out of the coagulation bath liquid, wherein certain requirements are met.

Abstract: A method of producing a carbon fiber bundle suppresses penetration of a process oil agent into the fiber surface layer and suppresses adhesion between fibers and the generation of surface voids, and also provides a carbon fiber bundle. The carbon fiber bundle is characterized by having a crystallite size of 3.0 nm or less as measured by wide-angle X-ray diffraction, containing a point where the Si/C ratio is 10 or more as calculated by SIMS (secondary ion mass spectrometry) in the region ranging from 0 to 10 nm in depth from the fiber surface, and also showing a Si/C ratio of 1.0 or less as calculated by SIMS at a depth of 10 nm from the fiber surface.
