Abstract

1313956 Carbon fibres KUREHA KAGAKU KOGYO KK 11 Nov 1970 [11 Nov 1969] 53580/70 Heading C1A Carbon fibres are produced from pitch-like or resinous materials obtained from residues of petroleum refining and having a carbon content of from 89 to 96À5% by weight by melt spinning, infusibilizing and carbonizing the raw material and in the period from melt spinning to the early stage of carbonization where the treatment temperature is below 650‹ C. and the fibres are still in an extremely fragile condition rendering the spun fibres into fibrils of short length. The disintegration of the spun fibres may be accomplished by blowing a stream of oxidizing gas on to the freshly spun fibre in a direction perpendicular to the axis of the fibres. The temp. of this gas may be in the range from normal ambient to 400‹ C.
