PURPOSE:To obtain the title treated yarn useful for tires, etc., having excellent adhesiveness and resistance to flex fatigue, by immersing carbon fiber in a mixed treating agent of an uncured thermosetting resin and a rubber latex and heating and drying while twisting. CONSTITUTION:Carbon fiber yarn (e.g. carbonized fiber yarn; preferably having 1,800-3,600 total deniers and 3,000-6,000 filaments) is immersed in a mixed treating agent of an uncured thermosetting resin (e.g. an aqueous solution of alkaline initial condensate of resorcin and formaldehyde) and a rubber latex and heated and dried at 150-2500 deg.C for 30-120 seconds with dry air while twisting (preferably 1-2 times/10 cm twists) to give the objective treated yarn. The plural treated yarns are arranged to give a cord having excellent resistance to flex fatigue. |
