摘要： The present invention pertains to a core wire for a drive belt, the core wire including twisted cords in which a plurality of first-twisted threads are doubled and final-twisted, each first-twisted thread including a plurality of hard first-twisted threads (A) and one soft first-twisted thread (B), the hard first-twisted threads (A) including aramid fibers, and the fineness of each hard first-twisted thread (A) being 1500 dtex or less, the soft first-twisted thread (B) including low-elasticity fibers, and the ratio (B/A) of the first-twist coefficient of the soft first-twisted thread (B) to the average value of the first-twist coefficient of the hard first-twisted threads (A) is 0.5-1.2.

摘要： The present invention relates to a transmission belt core wire production method comprising a first processing step of processing an unprocessed string for a transmission belt core wire with a first processing agent containing a resin component (A) to obtain a first processed string, and a second processing step of processing the first processed string with a second processing agent containing a condensate (B1) of resorcinol and formaldehyde, non-modified latex (B2), and an acid-modified diene-based polymer (B3), to obtain a second processed string.

摘要： A rubber-reinforcing cord (12) of the present invention includes at least three strands. Each of the strands includes at least one filament bundle and a first coating provided to cover at least a portion of the surface of the filament bundle. The filament bundle consists essentially of aramid fiber filaments. The mass of the first coating is in the range of 14 to 25% with respect to the mass of the filament bundle. Each of the strands is given primary twists at a primary twisting rate of 50 to 100 twists/m. The at least three strands each given primary twists are assembled and given final twists at a final twisting rate of 120 to 200 twists/m.
