Abstract
A cable wrap fabric for protecting a communications cable is woven of fiberglass yarns plied with or without low melt thermoplastic yarns, and water swellable superabsorbent yarns. The water swellable superabsorbent yarns are interspersed at spaced intervals within the fiberglass yarns. The fiberglass yarns dissipate heat energy created by lightning strikes or excessive thermal shocks. The superabsorbent water swellable yarns block the progression of water through the cable. The low melt thermoplastic yarns, if used, fuse the other component yarns of the fabric together so that the fabric can be slit into the required tape widths without excessive yarn fraying at the edges.
