Abstract

Electrospinning provides a relatively versatile method of creating a variety of ultrathin nanofibers. One of the well known problems in electrospinning is low productivity. To increase the inherently low productivity in electrospinning, an assembly of multi-needles has been widely introduced. This process may be enhanced by introducing the electroblowing process that combines air blowing and electrospinning. In this study, the effect of electroblowing on web deposition was explored via the simultaneous and separate application of two forces: an electrostatic force and an air blowing-induced shear force, which are adjusted by the applied voltage and the air blowing pressure, respectively. The image filtering technology was used to evaluate the web deposition. The application of the shear force significantly affected the web deposition, especially at low voltage.
