Abstract: A protective sheath made of a woven synthetic fabric having a structure formed of high tenacity warp and weft yarns, the count of the yarns ranging from 400 to 2000 decitex and the number of the yarns ranging from 54 to 78 yarns per centimeter. The woven synthetic fabric is chemically finished with continuous dyeing process.

Abstract: A protective sheath is intended to cover a flexible tube or hose used for conveyance of a working fluid to a hydraulic or pneumatic device, and is formed of a strip that is helically wound around an outer surface of the flexible tube. The strip comprises: a core of electrically insulating and flame retardant material; and a core-covering layer of electrically conductive and flame retardant material having a first surface portion intended to contact the outer surface of the flexible tube, and a second surface portion opposite to the first surface portion and forming an on sight surface of the strip when it is wound around the flexible tube. The core-covering layer of electrically conductive material dissipates electrostatic charges which are formed on the outer surface of the flexible tube, and protects the outer surface of the flexible tube from wear and flame by performing a flame retardant action.
