Abstract: The cellulose film was prepared using cellulose LiCl/DMAc solution which formed by cotton pulp dissolved in LiCI/DMAc solvent through wetting-spinning process . The Structure of cellulose film was characterized by means of FT-IR and XRD. The effects of the kind of coagulation bath、the cellulose concentration of cellulose LiCl/DMAc solution、the LiCl/DMAc concentration and temperature of coagulation bath on mechanical properties of the films were investigated. The results showed that the uniformly and transparent cellulose film with cartain intensity could be prepared when the cellulose concentration is 6-7％、the water solution which LiCl/DMAc containing is 10~15% and the temperature is 20℃ as coagulation bath.
