Abstract

A method for producing microfibers includes the steps of (a) providing a base material; (b) forming the base material in a ring; (c) gripping opposing ends of the ring; (d) flipping one of the opposing ends relative to the other of the opposing ends, forming an upper portion and a lower portion; (e) folding the upper portion onto the lower portion; (f) stretching the folded upper and lower portions; and repeating steps (d)-(f) as desired. Different apparatuses for performing the method are also provided.
