<p>A toothed belt (1) having a treated light-colored tooth cloth (6) comprised of a first layer (9) in which rubber is impregnated in an original canvas (7), a second rubber layer (10) formed on a surface side of the first layer (9), and a third rubber layer (11) formed on the back side of the first layer (9) and adhered to the belt body rubber layer (3). The rubber of the first layer (9) may be obtained by formulating polytetrafluoroethylene, phenol resin, titanium oxide, a potassium titanate fiber and zinc methacrylate in a mixture obtained by formulating a hydrogenated nitrile rubber and a polymer alloy in which zinc methacrylate is finely distributed in the hydrogenated nitrile rubber in a range of parts by weight of 95:5 to 60:40.</p> |
