Abstract
The tension member for a belt of this invention is made from a glass cord. First twist yarns of this glass cord are obtained by paralleling and twisting a plurality of fiber bundles, each including a large number of glass filaments, by a predetermined first twist number. The fiber bundles are previously soaked with a treatment liquid including a mixture of rubber latex and an initial condensation product of resorcinol and formalin as a main component and then heated. The glass cord is fabricated by paralleling a predetermined number of the first twist yarns and twisting them by a predetermined final twist number, so as to squeeze and substantially eliminating spaces among the first twist yarns. Accordingly, the belt including this glass cord as the tension member can achieve good water resistance because externally intruding water is prevented from being held within the belt.
