The DITF has been presented with the Cellulose Fiber Innovation of the Year 2022 Award for its research results on the production of carbon fibers from wood. The project demonstrates resource-saving alternatives to fossil-based fibers.
For the 2nd
time, nova-Institut GmbH, Hürth/Germany, honored outstanding scientific research that provides sustainable solutions for the cellulose fiber value chain at the “International Conference on Cellulose Fibers 2022” on February 2-3, 2022. The conference sees itself as an international forum for the development of new cellulose fibers and materials and their manufacturing processes.
The Competence Centre Biopolymer Materials at the German Institutes of Textile and Fiber Research Denkendorf (DITF), Denkendorf/Germany, received 1st
place in the nomination with its presentation of carbon fibers, which are obtained from the raw material wood in a novel and sustainable process. The HighPerCellCarbon technology describes a patented process that has been further developed under the leadership of Dr. Frank Hermanutz: As a result, carbon fibers based on biopolymers can be produced in a sustainable and particularly environmentally friendly process.
The HighPerCellCarbon process involves the wet spinning of cellulose fibers using ionic liquids (IL) as direct solvents. The filament spinning process is the central technical part. It takes place in an environmentally friendly and closed system. The IL is completely recycled. The cellulose fibers produced in this way are converted directly into carbon fibers in a further development step by a low-pressure stabilization process, followed by a suitable carbonization process. No waste gases or toxic by-products are produced during the entire process sequence.
Carbon fibers are used in many lightweight construction applications. Global demand has been characterized by significant growth rates for years.
