摘要： Provided are: a carbon fiber bundle which has a large value of single-fiber fineness and excellent productivity and which, despite this, contains few interlaced single fibers therein and has excellent spreadability; and precursor fibers which are suitable for use in producing the carbon fiber bundle. The precursor fibers are a carbon-fiber-precursor acrylic fiber bundle which comprises a polyacrylonitrile copolymer comprising 95-99 mol % acrylonitrile units and 1-5 mol % hydroxyalkyl (meth)acrylate units and which has a single-fiber fineness of 1.5-5.0 dtex. In the acrylic fiber bundle, the cross-section of each single fiber which is perpendicular to the fiber axis has a shape that has a roundness of 0.9 or less. The roundness is a value determined using equation (1) where S and L are the cross-sectional area and the circumferential length, respectively, of a single fiber which are obtained by examining, with an SEM, the cross-section of the single fiber which is perpendicular to the fiber axis and analyzing the obtained image. Roundness=4pS/L2  (1)

摘要： Provided is a carbon fiber manufacturing method including a surface treatment step of ejecting an ozone solution in which ozone is dissolved in solvent from a fluid ejecting port toward a carbon fiber bundle and causing the ozone solution to pass between single fibers of the carbon fiber bundle so as to contact surfaces of the single fibers so that the surfaces of carbon fibers are treated by the ozone solution. Also, provided is a carbon fiber subjected to a surface treatment by the carbon fiber manufacturing method.
