Abstract
The present invention relates to twisted yarn obtained by twisting a plurality of carbon fiber resins which are slit from a carbon fiber resin tape in which adhesive, alumina sol, and potassium persulfate permeate between a plurality of the carbon fibers spread flatly. An open yarn is obtained by S-twisting and Z-twisting covering yarn around the periphery of the twisted yarn. A carbon fiber covered twisted yarn is obtained by winding the twisted yarn around the periphery of a core material.
