摘要： It is an object of the present invention to provide a package in an optimal form obtained by winding a carbon fiber bundle having a fineness of 25,000 to 35,000 deniers, which has a high wound density and is less apt to become loose, and a method for producing the same. The present invention is a carbon fiber package obtained by winding a carbon fiber bundle having a fineness of 25,000 to 35,000 deniers on a bobbin in a square-end type, wherein the width per unit fineness of the carbon fiber bundle is in the range of 0.30×10 -3 to 0.63×10 -3 mm/denier, the traverse angle in the beginning of winding is in the range of 13 to 14°, the traverse angle in the end of winding is 3° or larger, and the fractional portion W0 of the winding ratio W is in the range of 0.07 to 0.08.

摘要： A package in an optimal form obtained by winding a carbon fiber bundle having a fineness of 25,000-35,000 deniers. It has a high winding density and is less apt to become loose. Also provided is a process for producing the package. The carbon fiber package is one of the square-end type obtained by winding a carbon fiber bundle having a fineness of 25,000-35,000 deniers on a bobbin. In the carbon fiber package, the width range per unit fineness of the fiber bundle is 0.30 x 10-3 to 0.63 x 10-3 mm/denier, the traverse angle in the beginning of winding is in the range of 13 to 14°, and the traverse angle in the end of winding is 3° or larger. The proportion of the number of ends (W0) in the winding ratio (W) is in the range of 0.07-0.08.
