Abstract (en)

[origin: EP0313736A2] To lower the spinning temperature, it is proposed, prior to spinning, to mix the bituminous high-melting carbon fibre precursor with an alcohol which is present in the supercritical state. Surprisingly, no gas or solid is occluded in the fibre. The re-formation of solid matter is prevented.
