DITF project produces yarns from regional beech wood using a closed-loop ionic liquid process — a potential low-impact alternative to viscose
DENKENDORF — The German Institutes of Textile and Fiber Research (DITF) have announced the production of cellulose staple fibre yarns for apparel under a new research project called InnoCell, marking the first time its patented HighPerCell process has been adapted to produce staple fibre.
HighPerCell dissolves cellulose in ionic liquids and spins it into continuous filaments within a closed-loop system. Unlike the viscose process, which relies on toxic carbon disulfide and generates significant chemical waste, HighPerCell claims to recover more than 99% of its solvent and produce no harmful by-products.
