• Nano fibers refer to ultra-fine threads less than 1,000 nm
(1 nm = 1 billionth of a meter). (In general, it refers to less than 100 nm
but up to 1,000 nm is recognized in the textile industry)
• Normal fibers create threads by applying high pressure, but Nano fibers
spin threads by applying an electric field instead of high pressure.
This is called 'electro spinning'.
