摘要： 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 [TBDH]+ 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.
