摘要： The present invention relates to a carbon fiber sizing agent comprised of water-soluble thermoplastic resin and amphoteric surfactant within a weight ratio range of 6/1 to 1/3, a carbon fiber sizing method comprising treating carbon fibers using a sizing liquid containing the aforementioned sizing agent, sized carbon fibers comprising adhering the aforementioned sizing agent to their surfaces, and a fabric that uses said carbon fibers. The carbon fiber sizing agent of the present invention has satisfactory solubility in water over a wide pH range, and is able to impart to carbon fibers adequate convergence for forming stable chopped carbon fibers, superior workability and satisfactory uniform tow dispersibility in water over a wide pH range. Since a fabric of the present invention demonstrates affinity to water over a wide pH range, it is suitable for applications such as immersing said fabric in an aqueous matrix in order to impregnate the fabric with that matrix.
