<p>A reinforced hose, comprising an inner tuber rubber layer (1), a cover rubber layer (5) at least two reinforcing thread layers including an upper thread layer (4) and a lower thread layer (2), and disposed between the inner tube rubber layer (1) and the cover rubber layer (5), and at least the lower thread layer (2) including a polyester thread having the following physical properties: a tensile strength of 8 grams or more per a unit denier, an elongation of (10 +/- 1.5) %, and a loaded elongation of (2.7 +/- 1.0) % per a unit denier under 3-grams load. With this construction, the reinforced hose satisfies the fatigue resistance and the volume expansion simultaneously. <IMAGE></p> |
