Abstract
Abstract Tubular sleeves of braided, knited or woven construction comprised of bulky continuous filament yarns and a resilient engineered plastic monofilament have excellent noise reduction characteristics. The bulky yarn provides a flexible cushion for cables and tubes covered by the sleeves thereby reducing vibration induced wear. The resilient monofilament gives the sleeve material sufficient hand so that sleeves formed according to the invention tend to assume the open position without loss of the ability to deaden sound and cushion vibration.
