Abstract

The current study focuses on the development of a novel electrospinning method with high productivity for nanofibre yarn production. By analysing different recent approaches for nanofibre yarn preparation systems it was found that getting rid of mechanical contacts between the fibres and the collector before the formation of the yarn leads to a significant growth in the production rate. A novel electrospinning unit was designed and tested. The formed fibres were aligned and twisted over the core yarn using a column with rotary air movement. The produced core-shell yarns were studied under scanning electron microscope to determine the morphology of the fibres and yarns. Also, the linear density of the yarn was calculated to determine the growth in mass after covering the core yarn with nanofibres.
