Braided hose and method of making same

摘要

A hose including at least one rubber layer, an outer cover, and at least one barrier layer provided between the rubber layer and the outer cover, wherein the barrier layer is configured to prevent rubber from the rubber layer from reaching the outer cover during curing of the hose. In one embodiment, the rubber layer is the hose inner tube and the outer cover is braided wire. In another embodiment, the barrier layer includes at least one layer of polymeric film. In another embodiment, the hose can include at least one reinforcing layer provided between the rubber layer and the barrier layer. In another embodiment, the hose can include at least one intermediate layer provided between the rubber layer and the barrier layer, where the intermediate layer is formed from a porous material. In another embodiment, the hose can include at least one retaining layer provided between the barrier layer and the outer cover, where the retaining layer is formed from a polymeric material. Optionally, a composite barrier/retaining layer can replace the separate barrier and retaining layers.
