Abstract
A yarn producing apparatus that produces high-density carbon nanotube yarn at high speed. The yarn producing apparatus includes: a substrate support supporting a carbon nanotube (CNT) forming substrate; a winding device configured to continuously draw CNT fibers from the CNT forming substrate supported on the substrate support and to allow the CNT fibers to run; and a yarn producing unit provided between the substrate support and the winding device to directly take in the CNT fibers drawn by the winding device and twist the taken-in CNT fibers. The yarn producing unit false-twists the CNT fibers with a swirl flow of compressed air.
