Abstract
This article presents a novel approach towards tackling the balance between filter efficiency and pressure drop by layering micro and nano fibres using melt and solution electrospinning. Polyamide fibre mats were fabricated by a prototype fibre printing apparatus, based on a combination of melt and solution electrospinning. Fibrous mats with favorable filtration performance characteristics were developed by optimizing the process parameters. The measurements were performed at a face velocity of 5.3 cm/s. High filtration quality factors (such as 0.068–0.085 Pa-1 for PN1 fraction) were reached due to low values of pressure drop (15.92–50.17 Pa). The filtration efficiencies ranged from 93.7 (PN1) to 98.5% (PN10). Higher ratios of nano-sub micrometer (<1 μm) to super micrometer (≥1 μm) fibres in the fibrous matrix were associated with the higher filtration quality factors.
