摘要： A method for producing a fiber assembly, including: putting a plurality of fibers and a fiber treatment agent into a stirring tank; and stirring a mixture of the fibers and the fiber treatment agent with a stirring blade to granulate the mixture, wherein the fibers include carbon fibers, and the mixture is granulated such that the fibers are aligned. A method for producing a fiber assembly, wherein a plurality of fibers containg carbon fibers and a liquid are put into a stirring tank and the mixture of the fibers and the liquid is stirred with a stirring blade, thereby obtaining a fiber assembly which has a spheroidal shape or a strand shape.

摘要： A carbon fiber bundle containing a sizing agent particularly suitable for combination with a thermoplastic resin is provided, wherein the sizing agent has an appropriate level of bundling property for ease of handling and is susceptible to thermal degradation at temperatures low enough to maintain the surface properties of the carbon fibers, and wherein the residual amount of sizing agent can be reduced after the carbon fiber bundle is processed into an intermediate substrate, resulting in a reflection of the surface properties of the carbon fibers.
