    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: PROBLEM TO BE SOLVED: To efficiently produce a chopped carbon fiber strand which has a high bulk density, an excellent compounding property, and is suitable for carbon fiber-reinforced composite materials. SOLUTION: This method for producing a chopped carbon fiber strand comprises subjecting a polyacrylonitrile-based fiber bundle comprising 30,000 to 350,000 filaments in a substantially non-twisted state to a flame-proofing treatment, a carbonization treatment and a surface treatment to convert the fiber bundle into a carbon fiber bundle, and then continuously subjecting the carbon fiber bundle to a sizing treatment and a cutting treatment. Therein, the carbon fiber bundle has a bundling ability having a fiber-interlaced value (CF value) of 10-70 1/m by a hook drop method.

    Abstract: PROBLEM TO BE SOLVED: To improve the passing property in a higher level without using any binder by laminating fiber bundles whose ductility is not more than a specified value on each other so that the flatness is within a specified range, and connecting them through the slip in the rapid fluid treatment to reduce the breakage or scatter of the fiber. SOLUTION: A fiber bundle is a low ductility fiber bundle whose ductility is not more than 3%, includes a glass fiber bundle, an Aramid fiber bundle and a carbon fiber bundle, and is characterized as being high in strength, high in elasticity and brittle. In connecting the bundle, fiber bundles 4 are arranged approximately parallel to each other in order to laminate the fiber bundles 4 on each other, and the fiber bundles 4 are pulled and arranged in a flat shape without any stranding. The flatness of a laminated part is within a range of 10-500, preferably 25-250. The rapid fluid treatment is preferably effected by using air, a nozzle 1 is provided with a rectangular or elliptical area, and a circular ejection hole 2 is preferable. This method is preferably used in connecting fiber bundles to each other when switching a raw fiber bundle.

    Abstract: PROBLEM TO BE SOLVED: To provide a carbon fiber precursor acrylic thick filament yarn package having a good wound shape and not causing the lack of lease or single filament winding in dissociating it when a large quantity of the carbon fiber precursor acrylic thick filament yarn is wound around a core bobbin and provide its manufacturing method. SOLUTION: This carbon fiber precursor acrylic thick filament yarn package is characterized in that the yarn width and the yarn displacement rate on the package can be specified in a cylindrical package composed by winding the carbon fiber precursor acrylic thick filament yarn on the bobbin. The manufacturing method of the package is characterized in that when the carbon fiber precursor acrylic thick filament yarn is wound on the bobbin, the winding angle from the start of the winding to the end of the winding is controlled in the range of 3-18 deg., and the filament yarn is wound by controlling the tension of the filament yarn from the start of winding to the 300 kg winding in a specific range.
