Novel method for producing electrospun composite nanofibre yarns

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