ABSTRACT:
A flexible, thermoplastic hose for high pressure and high velocity flow is provided with a flexible braided reinforcement layer with a static drain therein for conducting static electricity towards a ground. This is achieved by having at least one textile fiber yarn with conductive fibers therein braided with non-conducting textile yarns to form the braided reinforcement layer. The preferred conducting fiber yarn is formed with metal fibers as well as plastic fibers. A method of manufacture of the hose comprises providing electrical conducting yarns and non-conducting yarns in a braiding machine and braiding them about a tube having a hollow bore through which fluid flows. An abrasion resistant outer cover layer of polyurethane is extruded over the braided layer having the drain therein. For higher pressure applications, a second braided reinforcement layer may also be provided over the inner braided layer having the electrically conductive yarns. Several conductive yarns may be used to have spaced electrically conductive yarns, e.g., at 3:00, 6:00, 9:00 and 12:00 in a circular cross-section through the hose.
