Abstract
A single layer/ply multi-use hose is contemplated. A thermoplastic polymer, such as polyurethane, is extruded through a woven tubular mesh of aramid fibers so as to encourage pillaring through gaps in the mesh of a sufficient amount to improve the overall durability and strength of the resultant hose. This wide diameter (at least 4 inches) and long continuous length (at least 300 feet) hose exhibits excellent durability (e.g., resistance to abrasion and/or punctures) and tensile ratios in excess of 2:1 so as to withstand tensile loads in excess of 100,000 pounds without delamination or bubbling within the hose wall.
