For the second time, the nova-Institute for Ecology and Innovation honored outstanding scientific research that provides sustainable solutions for the cellulose fiber value chain at the “International Conference on Cellulose Fibers 2022”. For their research results on the production of carbon fibers from wood, the German Institutes of Textile and Fiber Research Denkendorf (DITF) was awarded “Cellulose Fiber Innovation of the Year”.
The conference is an international forum for the development of new cellulose fibers and materials and their manufacturing processes. Exhibitors include leading fiber manufacturers; participants come from thirteen countries. The six competitors nominated for the award presented products that combine sustainable production processes with new technologies and applications to form cellulose-based materials.
The Competence Centre Biopolymer Materials at DITF Denkendorf received first place in the nomination with its presentation of carbon fibres, which are obtained from the raw material wood in a novel and sustainable process. The HighPerCellCarbon® technology describes a patented process that allows carbon fibers based on biopolymers to 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 and it takes place in an environmentally friendly and closed system. The solvent (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.
