Nanofiber yarn spinning system

A nanofiber spinning system comprising:

• a yarn winding device for receiving a false twisted nanofiber yarn;
• a first guide for providing a tension to an untwisted nanofiber yarn;
• and
• a first yarn spinner between the yarn winding device and the first guide, the first yarn spinner comprising a first moving surface for a first contact with an exterior surface of the untwisted nanofiber yarn,
• wherein the first guide is selected from a hoop, a hook, or a post;
• the first contact is configured to provide a friction to a first portion of the untwisted nanofiber yarn;
• the first moving surface is configured to cause the first portion of the untwisted nanofiber yarn to twist;
• and
• the first yarn spinner comprises:
• a frame with an enclosed circular opening;
• a circular bearing mounted to the circular opening, the circular bearing having an outer diameter proximate to the circular opening and an inner diameter opposite the outer diameter;
• and
• a first rotational twist ring having an outer surface mounted to the inner diameter of the circular bearing, an exposed inner surface, and a radius of the first rotational twist ring surface curvature less than 1 centimeter,
• wherein the inner surface of the first rotational twist ring is configured to be the first moving surface for the first contact with the exterior surface of the untwisted nanofiber yarn, and an inner diameter of the first rotational twist ring is 100 mm.
