ABSTRACT:
A process for the surface treatment of carbon fiber tows each consisting of a multiplicity of filaments, comprises treating the tows by electrolytic oxidation, using each tow as a positive electrode and applying an electric current in the form of pulses. The pulse spacing is such that the electric supply and non-supply durations are 0.02-20 sec. each, preferably 0.1-5 seconds each. The pulse shape is rectangular, triangular, or sine waves. The applied voltage is 3-15 V and the current density 0.2-1000 A/m.sup.2, preferably 1-100 A/m.sup.2, more preferably 5-20 A/m.sup.2. The electrolyte is an aqueous solution of an oxidizing agent, strong acid or base, neutral salt, or weak acid or base.
