ABSTRACT:
A hose construction having means for dissipating static electricity and method of making same are provided and such hose construction comprises a polymeric inner tubular layer, a braided layer disposed against the inner tubular layer and comprised of a plurality of filaments, and an electrically conductive layer made of carbonaceous particles overlying the braided layer and including particles dispersed between the filaments, the particles are disposed in overlapped relation in layer form and enable relative movement therebetween while maintaining electrical continuity to enable dissipation of the static electricity. The hose construction may comprise an additional braided layer disposed around the electrically conductive layer and sandwiching the electrically conductive layer between the braided layers as well as a protective layer disposed around the entire hose construction.
