Abstract
A plied cord includes three or four first twist yarns containing para-aramid fibers, wherein: the para-aramid fibers have an average size of 1000-1250 dtex, a tensile elasticity of 55-70 GPa and a tensile strength of 2800-3500 MPa; and for the plied cord, the number of first twists when the number of the first twist yarns is three is 33-40 twists/10 cm and the number of first twists when the number of the first twist yarns is four is 42-52 twists/10 cm, the second twist direction is the opposite direction from the first twist, and the ratio of the second twist coefficient to the first twist coefficient is 0.25-1.
