Patent ID: 8502069

Claim:
A protective sleeve for lengths of material such as electrical cable, hoses, ropes, hydraulic lines, tethers, and lanyards used in environments such as airports, docks, and construction sites in which said lengths of material are moved back and forth across abrasive surfaces and subjected to abrasion, chemicals, moisture, and weather extremes, said protective sleeve encasing said length of material, having open ends and formed of an elongated sheet consisting of a woven, lightweight fabric, with a thermoplastic film bonded to at least one side thereof, the fabric being made substantially of yarns formed primarily of long chain polyethylene fibers having a tensile modulus equal to or greater than 150 grams/denier, and a tenacity equal to or greater than 20 grams/denier, the yarns having a denier between 400 and 1000, the fabric having a warp and fill density of between 30 and 36 ends per inch, and the thermoplastic film selected from the group consisting of polyethylene and ethylene vinyl acetate, wherein the protective sleeve not only protects the lengths of material thereunder, but the fabric yarns themselves are resistant to deterioration from chemicals, fuels, as well as being highly resistant to abrasion, cuts, and the fabric of the sleeve is resistant to heat build-up as a result of relative movement between the sleeve and the length of material.
