Résumé : |
A novel non-imidazolium based ionic liquid has been identified as very good cellulose solvent to spin fibers in a lyocell-type dry-jet wet spinning process. The spinning temperatures are markedly lower which reduces bath energy consumption and cellulose degradation. The resulting fibers showed high mechanical properties, exceeding those of currently commercially available man-made cellulosic textile fibers. Deriving from lyocell, the fibers have been called loncell-Ribers). Demonstrator garments and textile products have been produced to evaluate the potential of the new solvent-based process. In addition, a wide spectrum of cellulosic solutes could be dissolved, including low refined cellulose pulp and waste material. This could open up new opportunities in waste recycling strategies and sustainable resource management Further, the mechanical properties of the loncell fibers show promising prospect for technical applications such as reinforcement structures for (bio) composites or precursor for bio-based carbon fibers. |
