Electrostatic and Plasma Spinning for Nanofibre Yarns
topic
Electrospinning applies high voltage of 10 to 30 kilovolts between a polymer solution nozzle and a collector electrode, drawing a continuous fibre from the Taylor cone formed at the nozzle tip by electrostatic forces stretching the polymer jet into nanofibres of 50 to 2000 nanometre diameter collected as a nonwoven mat or twisted into nanofibre yarns for filtration, biomedical scaffold, and sensor applications.
Role
Produces fibres at diameter scales inaccessible by conventional melt or solution spinning for applications requiring ultrafine fibre dimensions including HEPA-grade filtration membranes, tissue engineering scaffold matrices, and sensor textiles where the nanometre-scale fibre diameter provides extremely high surface area per unit mass that governs filtration efficiency, cell adhesion, and sensing sensitivity.
