Nano Fiber

Nano FiberNANOFIBERS ARE DEFINED AS FIBERS WITH DIAMETERS LESS THAN 100 NANOMETERS. IN THE TEXTILE INDUSTRY, THIS DEFINITION IS OFTEN EXTENDED TO INCLUDE FIBERS AS LARGE AS 1000 NM DIAMETER.
Properties of Nanofibers
Nanofibers exhibit special properties mainly due to extremely high surface to weight ratio compared to conventional nonwovens.
Low density, large surface area to mass, high pore volume, and tight pore size make the nanofiber nonwoven appropriate for a wide range of filtration applications.
Nanofibers are smaller compared to a human hair, which is 50-150 µm and the size of a pollen particle compared to nanofibers. The elastic modulus of polymeric nanofibers of less than 350 nm is found to be 1.0±0.2 Gpa.
Production of nanofiber The most common method for making nanofibers employs electrospinning that uses an electrical charge to draw nanofibers from a polymeric solution. This technique utilizes large voltages and is strongly influenced by the dielectric properties of the material. It is also impossible to electrospin many biopolymers without blending with another polymer; similarly, it is impossible to electrospin pure Teflon nanofibers without using another polymer as a core.
