<p>A transmission belt is made of a cord, a rubber or thermoplastic matrix, and an adhesion material which is able to adhere the cord to the rubber or thermoplastic matrix. The cord is made of at least two yarns, such that a first yarn has a melting or decomposition point T<SUB>1 </SUB>and a second yarn has a melting point T<SUB>2</SUB>, wherein T<SUB>1</SUB>>T<SUB>2</SUB>. A ratio of a linear density of the first yarn to a linear density of the second yarn is between 1,000:1 and 1:1, wherein the second yarn is fused to the first yarn. A method of making such cords includes intertwining the first and the second yarn and then heating to a temperature between T<SUB>1 </SUB>and T<SUB>2</SUB>, with the heating step being integrated with or followed by a step wherein the cord is subjected to a dipping treatment with a rubber adhesion material.</p> |
