Preliminary Study on the Fabrication Mechanism of Nanofibers in the Melt Splitting Process

Authors: Li Li Wu, Yuan Ling Cheng, Ting Chen

Abstract: Melt splitting is a new technique for the mass production of nanofibers. The polymer melt split radially into several hundred very fine filaments in a specially designed nozzle. The prediction model for filament diameter after splitting in the melt splitting process is established based on the surface wave method. The predicted filament diameter compares favorably with the experimental data. Effects of the air pressure and polymer flow rate on the filament diameter are studied. It is found that larger air pressure and smaller polymer flow rate can all produce finer filaments. The results provide a good foundation for the optimization of the melt splitting technique.
