Zusammenfassung:	According to an example aspect of the present invention, there is provided A process for making a cellulose fibre or film comprising the steps of dissolving pulp in an ionic liquid containing a cationic 1,5,7-triazabicyclo[4.4.0]dec-5-enium [TBDHJ+ moiety and an anion selected from the group according to Formula a), Formula b) and Formula c), wherein each of R, R2,R3,R4,R5, R7,R8, R9 and R10 is H or an organyl radical and X- is selected from the group consisting of halides, pseudohalides, carboxylates, alkyl sulphite, alkyl sulphate, dialkylphosphite, dialkyl phosphate, dialkyl phosphonites and dialkyl phosphonates, to provide a spinning dope, extruding the spinning dope through a spinneret to form one or more filaments, and a step selected from the group consisting of spinning cellulose fibres from the solution, and extruding a cellulose film from the solution. Selon un aspect donné à titre d'exemple, l'invention concerne un procédé de fabrication d'une fibre ou d'un film de cellulose comprenant les étapes consistant à : dissoudre une pâte dans un liquide ionique contenant un groupe 1,5,7-triazabicyclo[4.4.0]déc-5-énium [TBDHJ+ cationique et un anion choisi dans le groupe selon la formule a), la formule b) et la formule c),où chaque parmi R, R2, R3, R4, R5, R7, R8, R9 et R10 est de l'H ou un radical organyle et X- est choisi dans le groupe comprenant les halogénures, les pseudohalogénures, les carboxylates, le sulfite d'alkyle, le sulfate d'alkyle de dialkylephosphite, de phosphate de dialkyle, des phosphonites de dialkyle et des phosphonates de dialkyle, pour fournir un dopant de filage, extruder le dopant de filage à travers une filière pour former un ou plusieurs filaments, et une étape sélectionnée dans le groupe comprenant le filage de fibres de cellulose à partir de la solution, et l'extrusion d'un film de cellulose à partir de la solution.
