ABSTRACT:
An antistatic hose is provided, including an inner layer of insulation material having a cylindrical configuration; a first electrically conductive fiber spirally arranged within the inner layer; a second electrically conductive fiber longitudinally arranged within the inner layer and electrically connected to the first electrically conductive fiber at the crossing points therewith; a linear reinforcing member spirally wound around the external surface of the inner layer and adhered thereto; and a member for covering both the inner layer and the reinforcing member and adhered thereto. The antistatic hose is able to prevent a material conducted by the hose from being charged by static electricity and also to discharge the static electricity from the material. In addition, an anti-collapse characteristic is achieved by the spirally wound reinforcing member and the cover member strongly adhered to both the inner layer and the reinforcing member to prevent separation therebetween.
