  Abstract

The PLA nanofiber manufacturing technology using the melt electrospinning method requires the maintenance of the nozzle temperature (260?), so a non-contact induction heating method is to be applied. However, it is not easy to obtain experimental data on the heating and maintenance time of the induction heating method, so it is possible to secure the conditions through simulation of the process variables required for the process through finite element analysis. In this study, the nozzle part of the induction heating method was designed with a copper coil with a 3/16 inch outer diameter of 4.76 mm, an inner diameter of 3.24 mm, a thickness of 0.76 mm, and a gap of 2 mm. The induction heating analysis used an axisymmetric model, and the heating time was 5 seconds, the frequency was 40 kHz, the initial current was 150 A, and the number of turns was 5. It was confirmed that uniform PLA fiber production with an average diameter of 1.7±0.2 μm and 2.63 μm was possible at a feed rate of 150 rpm, a TCD of 150 mm, a voltage of 42 KV, and a melting temperature of 260 oC was possible.
