Abstract
An apparatus for manufacturing open carbon fiber superfine yarn comprises a yarn feeding part for feeding a carbon fiber bundle; a tank for storing water for opening carbon fiber to immerse the carbon fiber bundle in the water for opening carbon fiber; a first drying part for drying the open carbon fiber bundle formed by the immersion in the water for opening carbon fiber; an application part for applying a catalyst to the dried open carbon fiber bundle; a second drying part for drying the catalyst-applied open carbon fiber bundle to obtain open carbon fiber resin tape; a slitting part for slitting the open carbon fiber resin tape longitudinally; and a twisting part for twisting a plurality of the open carbon fiber resin tapes slit by the slitting part to form open carbon fiber superfine yarn.
