Abstract
The hose includes an outer jacket which includes warp and weft fibers made of Vectran®. The process for making the hose, includes: forming an inner liner and coating the exterior thereof with adhesive; weaving, in a twill weave pattern, Vectran® yarn, in a repeating 2-4-2-4-2 pattern in both the warp and the weft directions; extruding polyurethane onto the woven vectran yarn, the polyurethane extending into pillars between the warp and weft yarn, forming an outer liner; inserting the inner liner coated with adhesive within the outer liner; and, pressurizing the inner liner with steam expanding the inner liner and the adhesive into engagement with the Vectran® yarn and polyurethane pillars of the outer liner.
