Abstract
Disclosed is a method for processing a carbon fiber bundle, which can adjust bundling property, winding property and wear resistance of sizing fibers. The method includes following steps: (i) coating a sizing agent on at least one carbon fiber bundle, in which the sizing agent includes a thermoplastic resin; (ii) drying the carbon fiber bundle by hot air; and (iii) heating the carbon fiber bundle by an infrared light, in which a heating temperature of the heating is equal to or higher than a melting point of the thermoplastic resin.
