As part of the CUBIC project, the German Institutes of Textile and Fiber Research Denkendorf (DITF) is developing a continuous process for the production of lignin-based carbon fibers.
The process uses water-based lignin salt solutions to produce multifilament precursor fibers through dry-spinning, avoiding organic solvents and providing a more environmentally friendly approach to fiber production.
The fibers tows are then further processed: joining of tows, stabilization, continuous carbonization and electrochemical surface treatment.
