Effective method for high-throughput manufacturing of ultrafine fibres via needleless centrifugal spinning PROJECT TITLE :Effective method for high-throughput manufacturing of ultrafine fibres via needleless centrifugal spinningABSTRACT:A nozzle-free spinneret with a flow controller was applied to produce nanoscale fibres of both polymeric solutions and melts by centrifugal field. This centrifugal processing strategy can be used to fabricate non-woven webs composed of fibre diameters ranging from several microns down to 400 nm or less. The fibre morphology and diameter in melt needleless centrifugal spinning (NCS) can be controlled by varying the rotation speed, temperature, liquid properties and collector system. Solution NCS adds the operating parameters of the solution concentration and the solvent. The field emission scanning electron microscope images show that the average diameter of the fibres is approximately 2 ± 0.8 µm and 400 ± 100 nm for polyethylene terephthalate fibres (2400 rpm, 245°C) and polyvinylpyrrolidone fibres (20 wt%, 4000 rpm), respectively.
