Abstract:
Electrospinning technique is a simple and fast method to fabricate continuous fibres in a range of micro or nano diameters. There are many parameters that may affect the mechanical property of the fibre, but the flow rate of the melt material has an important influence on the geometrical property of fibre. This study aims to investigate the effect of constant or variable discharged flow rate on the fibre’s diameter when electrospinning of polycaprolactone melt and the acetic acid solution is used. A series of experiments were carried out using a custom-made electrospinning machine. The experiment used a peristaltic pump that produces pulse flow versus a syringe pump that generates a continues and uniform discharge flow. The study’s outcome confirmed that the type of the pump and its flow type has a significant effect on the minimum diameter of the fibres (P < 0.001) and using a syringe pump lead to have a bigger diameter fibre. Also using a peristaltic pump can cause a rupture in the produced fibers that could affect the mechanical properties of the produced fibres.
