Abstract (en)
[origin: WO2013144082A1] The invention relates to a lignocellulose spinning solution, regenerated fibres made of lignocellulose, and a method for the production thereof. The method according to the invention makes it possible for the first time for lignocellulose to be processed into fibres without previous chemical separation methods for removing substances accompanying the cellulose, such as lignin and hemicellulose, or thermomechanical pretreatment of the raw material. The invention uses specially adapted ionic fluids of the imidazole type as solvents for lignocellulose from various origins. From the nearly homogeneous spinning solutions produced therefrom, it is possible using commercial spinning apparatuses to obtain stable filaments with mechanical parameters comparable to those which can be obtained by commercial cellulose spinning methods. Neither expensive acquisition of cellulose nor thermal and/or chemical pretreatment of the wood raw material is necessary in this case.
