Abstract: A carbon fiber package in the form of cheese winding or inside-pull package is made of carbon fibers having a fineness of at least 25,000 deniers. The outer diameter, the bobbin diameter or inner diameter of the package, and the winding width are in specific ranges. A square end type package has a yarn width per fineness, an angle of wind at the start and end of winding, and a winding irregularity in specific ranges. A carbon fiber package body has a mean bulk density in a specific range. Troubles and disadvantages during use are eliminated, a high winding density is achieved, and winding collapse hardly occurs.

Abstract: An object of the present invention is to provide a precursor fiber for a high-grade carbon fiber which is less likely to cause fuzz without impairing the productivity. The carbon fiber precursor fiber has a weight average molecular weight, M w(F), of 200,000 to 700,000 and a degree of polydispersity, M z(F)/M w(F) (M z(F) indicates the Z-average molecular weight of the fiber), of 2 to 5. Also, a process for producing the carbon fiber precursor fiber according to the present invention provides a process for producing the carbon fiber precursor fiber. In addition, an object of the present invention is to produce a high-grade and high-quality carbon fiber while suppressing fuzz and fiber breakage even under oxidation-carbonization conditions including a high tension or high stretch ratio without impairing the productivity. The process for producing the carbon fiber according to the present invention is a process for producing a carbon fiber using the carbon fiber precursor fiber. Furthermore, the carbon fiber according to the present invention is a carbon fiber in which a crystallite size and parameters concerning a carbon fiber surface, the parameters determined by Raman spectroscopy, satisfy a specific relationship.
