Abstract:

The cellulose acetate/ DMAc solution is unable to be electrospun into ultra fine fiber. However, the cellulose acetate/meta-aramid solution with a mass ratio 1:2 can be successfully electrospun into uniform nanofibers. The beads on the nanofibers decreased gradually as the mass ratio of cellulose acetate/meta-aramid in the solution and the mass concentration of the solution increased. The thermal property of cellulose acetate/meta-aramid nanofibers improved significantly as compared with aramid nanofibers, and the thermal loss process of aramid nanofibers occurred at around 150℃, whereas it occurred at 250℃ for cellulose acetate/meta-aramid nanofibers.
