PURPOSE: To provide an apparatus tar treating the surfaces or carbon fibers by a photooxidation method capable of carrying out the continuous treatment even of a large amount of a long carbon fiber bundle, extremely simply performing the surface treatment, forming the apparatus into a relatively small scale and preventing ozone from leaking out of a treating chamber without requiring the post-treatment such as washing with water. CONSTITUTION: This apparatus for treating the surfaces of carbon fibers is obtained by arranging the first gas replacement mechanism 2 capable of replacing the atmosphere with oxygen gas, a treating chamber 1 capable of irradiating the carbon fibers with ultraviolet rays in an ozone atmosphere and the second gas replacement mechanism 3 having the function equal to that of the first gas replacement mechanism 2 in the order and forming a passage capable of passing and running a carbon fiber bundle 5 therethrough in the apparatus. Furthermore, in the apparatus, the carbon fiber bundle 5 is dried with a drying mechanism 4, then introduced into the first gas replacement mechanism 2, exposed to the oxygen atmosphere, subsequently introduced into the treating chamber 1, irradiated with the ultraviolet rays in the ozone atmosphere, passed through the second gas replacement mechanism 3 and led out to the outside of the system. Since active oxygen leaked out of the treating chamber 1 to the respective gas replacement mechanisms 2 and 3 is recirculated to the treating chamber 1, the active oxygen can effectively be utilized without causing the leaking thereof. |
