A new mechanism for the electrospinning of nanoyarns

Abstract A new electromechanical mechanism for spinning “core electrospun nanoyarn” is researched, designed, and implemented. SEM images have shown that the deposited nanofibers were wrapped helically around the core filament resulting in a core electrospun nanoyarn. The parameters of this mechanism such as feed‐in angles, twist rates, and take‐up speeds are analytically investigated. Twist rates of 500 to 750 revolutions per minute, core feed‐in angle of 0°, and take‐up speed of 1.5 cm/s were found optimum for successfully producing core electrospun nanoyarn. This nanoyarn is expected to find many applications in industrial and medical textiles. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
