[57] ABSTRACT
A flexible hose having a novel braided reinforcement layer wherein one braid member is a relatively stiff, uncrimped monofilament and the second braid member is a flexible textile material which is crimped around the stiff monofilament at each contact point in the braided spiral layer. The braided spiral imparts improved crush and kink resistance to the hose structure. The method of manufacture employs no mandrel and produces a balanced tension braided hose which may be preferably cured by open steam techniques.
