- Abstract
- Electro-spun PVDF nanofibers and PE/PP thermal-bond nonwovens were composited to obtain nanofiber-based yarns using a slitting and twisting technique. Nanofiberbased yarns were applied to string-wound cartridge filters and compared with commercial filters. The average pore size, air permeability, and filter efficiency evaluations were performed to compare PVDF-based nanofiber composite yarns with commercially available polypropylene (PP) string-wound cartridge filters. The filtration efficiency of the nanofiberbasedyarn string-wound cartridge filter significantly improved compared to the commercial filter. For a 5 μm particle size, PVDF-based nanofiber composite yarn filters showed a removal efficiency of above 96% and an improved filter efficiency of more than 26% compared to commercial filters. Nanofiber membranes limited to surface filtration can perform to depth filtration if they consist of nanofiber-based composite yarns. The design of nominal and absolute filters can be based on the content of the nanofiber-based compositeyarns. These results demonstrate that electro-spun PVDF-based composite yarns could potentially serve as string-wound cartridge filters during processing or pre-filtering in water treatment areas.
