Abstract
A high-strength, low weight, electromechanical cable is disclosed. The cable is formed by polyamide multifilaments impregnated with a hydrolytically stable polyurethane to form a protective coating. The coating provides load adjustment from fiber to fiber, eliminates abrasive self-destruction of the fibers during flexing of the yarn under load, protects the fiber to some extent from ultraviolet radiation, aggressive chemicals or abrasive particles and makes it possible to preform the yarn. The coating comprises a reaction product of a liquid tetramethylene glycol, an aliphatic/cycloaliphatic diisocyanate and a diamine coupling-curing agent. The impregnated fibers are dried, twisted and then heated to the melting temperature of the coating.
