Method for producing carbon fiber bundle |
| abstract |
The present invention provides a method for producing a carbon fiber bundle, the method comprising the following steps (b) to (e): (b) an oil agent application step of applying a silicone oil agent to a precursor fiber bundle to produce an oil-agent-attached precursor fiber bundle; (d) a stabilization step of subjecting the oil-agent-attached precursor fiber bundle to a stabilization treatment to produce a fire-proof fiber bundle; and (e) a carbonization step of carbonizing the fire-proof fiber bundle. The method is characterized in that the tack-free time of the silicone oil agent at 250°C is shorter than 40 minutes. |
