An improved collapse-resistant, reinforced hose of flexible polymeric material including a semi-rigid generally circumferentially disposed supporting structure which includes preferably a single layer of textile fabric reinforcement, the major portion of which is composed of treated polyester or nylon fibers. The polyester or nylon fibers are treated with an organic polyisocyanate and preferably a solution of at least 2 percent organic polyisocyanate in a non-reactive solvent. The hose has substantially improved bursting strength and resistance to vacuum collapse without the need of additional support, such as a metal wire insert. The invention is particularly useful for flexible radiator hoses used in automotive vehicle cooling systems. |
