Abstract
The present invention provides a process for preparing a yarn, which comprises introducing a raw material that comprises a carbon source and a catalyst into a reaction chamber having a heating means, converting the carbon source into a plurality of carbon nanotubes in a heating part of the reaction chamber with thermal energy supplied by the heating means, and growing the plurality of carbon nanotubes in the vertical direction to form a yarn by the interactions among the carbon nanotubes.
