I'm PhD student I want to electrospining cellulose but the cellulose fibers do not dissolve. First, I made 18% cellulose alkali, after pressing CS2, I put it under stereo, but there was no dissolution. Please help me . I also used NMMO solvent, that is, after preparing alkali cellulose, I poured 50% NMMO and it did not dissolve and I raised the temperature to caramelized state. Please give me a method for both items. Thank you very much.
Dear Ziba Fathi, cellulose is a family of biopolymers, each grade has its special solvents and electrospinning conditions. At least you should specify the type you are working with. Please have a look at the following documents. My Regards

Dear Abdelkader BOUAZIZ, thank you so much. Its a perfect answer to me. My cellulose grade is pine bleached pulp.
The most widely used industrial process of dissolving cellulose is the viscose process, where NaOH is used to swell cellulose, which is then reacted with CS2 to yield a cellulose derivative that more easily dissolves in alkaline aqueous solution https://www.sciencedirect.com/science/article/pii/S0167732210001327
Cellulose can be dissolved in organic solvents, such as N,N-dimethylacetamide (DMAc) in the presence of lithium chloride. In addition, tetrabutylammonium fluoride have been used to dissolve cellulose in dimethyl sulfoxide (DMSO). https://link.springer.com/article/10.1007/s10570-019-02907-x
