Abstract
The present invention relates to a method of producing a cord for a power transmission belt, the method including: a first treatment step of treating an untreated yarn of a cord for a power transmission belt with a first treatment agent including a resin component (A) to obtain a first treated yarn; and a second treatment step of treating the first treated yarn with a second treatment agent including a condensate (B1) of resorcin and formaldehyde, an unmodified latex (B2), and an acid-modified diene-based polymer (B3) to obtain a second treated yarn.
