MANUFACTURING METHOD OF CARBON FIBER

摘要

PURPOSE: A method for fabricating carbon fiber is provided to control spinning condition and solidifying condition of PAN fibers and to uniformly maintain fineness deviation. CONSTITUTION: A method for fabricating carbon fiber without fuzz comprises: a step of preparing polyacrylonitrile(PAN) precursor spinning solution containing 8-15 wt% of polyacrylonitrile polymers(100); a step of discharging the spinning solution from a spinneret and solidifying in a solidifying solution containing ZnCl_2(110); and a step of drawing the solidified precursor carbon fiber(120).
