Abstract
A method, system, and resulting linear fibrous formation are provided wherein a supporting linear formation defines a core that is transported through a spinning chamber. A coating of polymeric nanofibers enveloping the supporting linear formation in the spinning chamber. The coating of polymeric nanofibers comprises a flat stripe wound around the core into a helical form, the flat stripe created from a hollow electrically neutral nanofibrous plume generated in a spinning space above a spinning electrode during spinning by AC electric voltage in the spinning chamber.
