    Abstract: The precursor fiber bundle for manufacture of carbon fibers of the present invention is one fiber bundle in which a plurality of precursor fiber bundles for manufacture of carbon fibers, respectively consisting of 30,000 or more filaments are joined at their respective mating ends directly or through an intervening fiber bundle (for example, a stabilized fiber bundle) not generating heat at the stabilizing treatment temperature, and at the respective joining portions, the filaments of the respective adjacent fiber bundles are individually entangled with each other. The individual filaments are entangled with each other by treating the overlaid portions of flatly opened terminal and starring ends of fiber bundles by a jet fluid or needle punch. The one continuous carbon fiber bundle for manufacture of carbon fibers, though thick, has heat reserved less at the joining portions in the stabilizing treatment.

    Abstract: Disclosed is a method for producing carbon fibers which exhibit excellent adhesion to a matrix resin and have excellent processability. Specifically disclosed is a method for producing a sizing agent-coated carbon fibers, wherein at least one kind of sizing agent that is selected from the group consisting of sizing agents (a), (b) and (c) described below is used for coating, in each of said sizing agents a bi- or higher functional epoxy compound (A1) and/or an epoxy compound (A2) being used as a component (A), and said epoxy compound (A2) having a mono- or higher functional epoxy group and at least one functional group that is selected from among a hydroxyl group, an amide group, an imide group, a urethane group, a urea group, a sulfonyl group and a sulfo group. The method for producing a sizing agent-coated carbon fibers is characterized in that the sizing agent is applied to carbon fibers and the resulting is subjected to a heat treatment within the temperature range of 160-260°C for 30-600 seconds. (a) A sizing agent which is obtained by blending at least 0.1-25 parts by mass of a tertiary amine compound and/or tertiary amine salt (B1) having a molecular weight of 100 g/mol or more per 100 parts by mass of the component (A), said tertiary amine compound and/or tertiary amine salt (B1) being used as a component (B). (b) A sizing agent which is obtained by blending at least 0.1-25 parts by mass of a quaternary ammonium salt (B2) having a cationic moiety represented by general formula (I) or (II) per 100 parts by mass of the component (A), said quaternary ammonium salt (B2) being used as a component (B). (In the formulae, R 1 -R 5 each represents a hydrocarbon group having 1-22 carbon atoms, a group that contains a hydrocarbon having 1-22 carbon atoms and an ether structure, a group that contains a hydrocarbon having 1-22 carbon atoms and an ester structure, or a group that contains a hydrocarbon having 1-22 carbon atoms and a hydroxyl group; and R 6 and R 7 each represents a hydrogen atom, a hydrocarbon group having 1-8 carbon atoms, a group that contains a hydrocarbon having 1-8 carbon atoms and an ether structure, or a group that contains a hydrocarbon having 1-8 carbon atoms and an ester structure.) (c) A sizing agent which is obtained by blending at least 0.1-25 parts by mass of a quaternary phosphonium salt and/or phosphine compound (B3) per 100 parts by mass of the component (A), said quaternary phosphonium salt and/or phosphine compound (B3) being used as a component (B).
