Abstract

A method of making a rubber hose includes the steps of providing an inner rubber layer including a hollow part, and forming a first braided layer on the inner rubber layer by braiding a plurality of first yarn materials including a vinylon fiber made by a dry process such that the braided first yarn materials includes a braid formed in a three-over, three-under pattern. Next, a middle rubber layer is formed on the first braided layer. A second braided layer is then formed on the middle rubber layer by braiding a plurality of second yarn materials including a vinylon fiber made by a wet process such that the braided second yarn materials includes a braid formed in a two-over, two-under pattern. Finally, an outer rubber layer is formed on the second braided layer.
