文摘

Solution electrospinning (ESP) has been deeply investigated currently. However, the research of melt ESP remains silent except a few progresses in device improvements and process investigation. In order to get a deeper understanding of fiber characteristics in the melt ESP process, microscopic simulation method of dissipative particle dynamics (DPD) was used here to create ESP simulation system. Fiber dropping process and the effect of spring coefficient on Tug of war effect were successfully simulated. In addition, the theory of Tug of war effect and the effect of factors on it were simulated and studied systematically. Results showed that distance between two particles and end-to-end distance of chains had the same variation tendency. The stretching and refining theory of jet was acquired.
