PROBLEM TO BE SOLVED: To improve heat resistance up to about 150 deg.C on a heat resistant water hose. SOLUTION: A heat resistant water hose H is constituted by laminating an inner pipe layer A formed of EPDM, a reinforcing yarn layer C made of reinforcing yarn F and an outer pipe layer B. The reinforcing yarn F is formed by twisting a first yarn made of alamide resin and a second yarn made of nylon resin. An adhesive thin film by RFL treatment is formed on a surface of the second yarn. The heat resistant water hose H can be provided with high mechanical strength by the second yarn made of alamide resin and provided with large adhesive force against the inner pipe layer A and the outer pipe layer B by the second yarn made of nylon resin and having the adhesive thin film. |
