Abstract

1,267,994. Spinning yarns. KUREHA KAGAKU KOGYO K.K. 29 April, 1969 [30 April, 1968], No. 21684/69. Heading D1F. [Also in Division Cl] A twisted carbon yarn is produced by twisting carbon fibres together, holding the twisted yarn while subjecting it to a temperature of at least 100‹C higher than the temperature used to carbonise the fibres in a non-oxidising atmosphere. A suitable atmosphere is nitrogen and the fibres may be heated up to 1000‹C above the carbonising temperature.
