Abstract
The present invention thus provides a double-jacketed lay-flat fire hose having an inner tube for conveying fluid, an inner jacket surrounding the inner tube and an outer jacket surrounding the inner jacket. The outer jacket is made of an abrasion-resistant woven fabric material that includes four longitudinal, spaced-apart and generally parallel stripes formed each of a bundle of longitudinally aligned filament yarns. This outer jacket is less prone to trapping air between the outer jacket and the inner jacket.
