ABSTRACT:
Carbon fiber precursors from pitchy materials are processed by applying thereonto an aqueous emulsion containing a single silicone oil or a mixture of silicone oils selected from polydimethyl siloxane, phenyl modified polydimethyl siloxane and aminoalkyl modified polydimethyl siloxane and having kinetic viscosity at 25.degree. C. of 100 centistokes or less, an alkanolamine salt of aliphatic monocarboxylic acid with 8-18 carbon atoms, and one or more non-ionic surfactants selected from polyoxyethylene alkylphenylethers polyoxyethylene alkylates, polyoxyethylene alkylaminoethers, and aliphatic monocarboxylic alkanolamides such that 0.1-5 wt % by solid deposit on fiber from this aqueous emulsion apply to the pitch fibers during any of the processes from the spinning and to the oxidizing.
