Abstract

Provided is an organic fiber doubled-and-twisted yarn cord the twist structure of which is uniform and with which it is possible to reduce weight. A doubled-and-twisted yarn cord comprising an organic fiber characterized in that a total fineness is 5000-15000 dtex inclusive, a coefficient of twisted yarn length difference between untwisting yarns constituting the doubled-and-twisted yarn cord that is obtained by an expression: coefficient of twisted yarn length difference (%)=(maximum value of yarn length difference between untwisting yarns)/(average value of yarn length of untwisting yarns)×100 is 1.5% or less, and breaking strength is 7.0 cN/dtex or greater.
