Abstract: Two-ply belting having improved dimensional stability flexing characteristics and elongation characteristics is disclosed. The belting comprises a first synthetic fabric proximate to the friction rubber surface of said belting and a second synthetic fabric distal to the friction rubber surface. The modulus and flex fatique life of the first synthetic fabric is greater than the modulus and flex fatique life of the second synthetic fabric. Belting with accordance with this invention is useful in agricultural applications.
