Abstract
The purpose of the instant invention is to provide a superfine carbon fiber thread with excellent bending strength and repeated bending. To achieve this purpose, (1) a desired composite thread is produced by opening open carbon fibers, slitting the opened fibers, twisting the slit fibers and forming a composite with a composite thread; and (2) a composite thread is produced by performing a lamination process with a film (film of composite materials) while performing a fiber-opening process, and then slitting, twisting and heating the tread for stress relief.
