METHOD FOR MANUFACTURING A RUBBER HOSE

摘要

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.

1. A rubber hose, comprising:
an inner rubber layer comprising a hollow part; a first braided layer formed on an outer periphery of the inner rubber layer by braiding a plurality of first yarn materials; a middle rubber layer formed on an outer periphery of the first braided layer; a second braided layer formed on an outer periphery of the middle rubber layer by braiding a plurality of second yarn materials; and an outer rubber layer formed on an outer periphery of the second braided layer, wherein the first braided layer is formed by braiding the plurality of first yarn materials comprising a vinylon fiber made by a dry process such that the braided first yarn materials comprises a braid formed in a three-over, three-under pattern, and wherein the second braided layer is formed by braiding the plurality of second yarn materials comprising a vinylon fiber made by a wet process such that the braided second yarn materials comprises a braid formed in a two-over, two-under pattern.
