Patent ID: 7367176

Claim:
A rope adapted to engage a structural member comprising: a plurality of yarns, where at least one of the yarns comprises a first set of first fibers, where the first fibers extend the length of the rope such that the first fibers directly bear tension loads applied to the rope; and a second set of second fibers, where the first and second sets of fibers are combined using a false twisting process such that the second fibers do not extend the length of the rope, the second fibers indirectly bear tension loads on the rope, and when the rope contacts the structural member, the second set of fibers is primarily in contact with the structural member; wherein the first fibers substantially determine load bearing properties of the rope; the second fibers substantially determine abrasion resistance properties of the rope, where abrasion resistance properties of the second fibers are greater than abrasion resistance properties of the first fibers; and the second fibers substantially determine a coefficient of friction between the rope and the structural member, where a coefficient of friction of the second fibers is less than a coefficient of friction of the first fibers.
