Apparatus for manufacturing open carbon fiber superfine yarn

An apparatus for manufacturing open carbon fiber superfine yarn, comprising:

• 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 an open carbon fiber resin tape (F4),
• a slitting part (7) for slitting the open carbon fiber resin tape (F4) longitudinally, and
• a twisting part (8) for twisting a plurality of the open carbon fiber resin tapes (F4) obtained by the second drying part in order to form an open carbon fiber superfine yarn, said open fiber resin tapes (F4) being slit by the slitting part (8), wherein said slitting part (7) is provided to longitudinally slit the open carbon fiber resin tape (F4), wherein said slitting part (7) comprises a feeding tensioner (71), a slit roll (72), and a winding-up tensioner (73), wherein slit open carbon fiber resin tapes which are slit by said slitting part (8) are fed to the twisting part (8) while said slit open carbon fiber resin tapes are given tension by said winding-up tensioner (73).
