Dry spinning technology
DITF's dry spinning plant is designed for the production of precursor fibers (green fibers) for oxidic ceramic fibers.
The plant’s dry spinning process can produce green fiber multifilaments with up to 500 filaments. Different water-based, ceramic-forming spinning masses can be processed. The plant’s maximum productivity is approx. 1 kg/hour.
The DITF has basic know-how in the "design" and production of spinning masses for oxidic ceramic fibers, which can then be processed into green fibers via dry spinning. The institutes also have the expertise for all further thermal process steps and accompanying analytical procedures up to the production of the ceramic fibers.
