The present invention relates to a method for manufacturing precursor yarn comprising lignin, which may be further processed into intermediate carbon fibers and finally also carbon fibers. It also relates to carbon fibers and uses of said fibers. Said method involves applying a water-free spin finish.

Process for the manufacture of a precursor yarn

The present invention relates to a method for manufacturing a shaped body comprising lignin which may be further processed into intermediate carbon fibers and finally also carbon fibers. Uses of said fibers are also disclosed. The present invention addresses the problem of lignin leaching into a precipitation bath. The solution to this problem is a novel method for minimizing the loss of lignin through the addition of certain salts into the precipitation bath.

Process for the manufacture of a shaped body

The present invention relates to a method for manufacturing thermally stabilized, non-sticky and stretchable fibers, which may be further processed into intermediate carbon fibers and finally also carbon fibers. Uses of said fibers are also disclosed. Also a highly oriented intermediate carbon fiber is disclosed together with a highly oriented carbon fiber.
