ABSTRACT:
A method for spinning filament yarns of high strength, high modulus carbon fibers is provided by way of a melt-spinning process in which a heated inert gas or a non-oxidative gas such as hydrocarbons of small C-numbers is injected steadily onto the surfaces of spinning nozzles to stabilize and ease the melt-spinning.
