A belt for suspending and/or driving an elevator car includes a plurality of cords. Each cord includes a plurality of wires and at least one yarn thread disposed at an outer periphery of the plurality of wires. An elastomeric jacket substantially retains the plurality of cords. The at least one yarn thread is configured to promote adhesion of the elastomeric jacket to the plurality of cords and reduce fretting of the plurality of wires. A method of forming a belt includes arranging a plurality of wires into a cord, arranging one or more yarn threads at an outer periphery of the plurality of wires, arranging a plurality of cords into a selected arrangement and applying an elastomeric jacket to the cords to retain the cords. The one or more yarn threads are configured to promote adhesion of the elastomeric jacket to the cords and reduce fretting of the wires.

A yarn which contains a composite yarn composed of a core part containing a short fiber and a sheath part containing a synthetic fiber filament yarn, the core part and the sheath part being integrated via fluff of the short fiber getting between or entangled with the long fibers, the specific gravity of the yarn being adjustable in the range of 1.0 or more, a fishing line containing the yarn, and a method for producing the fishing line. The present invention provides an ideal fishing line which has a strong core-sheath structure, does not allow separation or detachment of the core part and the sheath part, is easy to handle, and also is excellent in strength, weatherability, and water resistance.

A rope structure adapted to engage a bearing structure while under load comprises a plurality of fibers, a matrix, and lubricant particles. The plurality of fibers is adapted to bear the loads applied to the ends of the rope structure. The matrix surrounds at least a portion of some of the plurality of fibers. The lubricant particles are supported by the matrix such that at least some of the lubricant particles are arranged between at least some of the fibers to reduce friction between at least some of the plurality of fibers and at least some of the lubricant particles are arranged to be between the bearing structure and at least some of the plurality of fibers to reduce friction between the bearing structure and at least some of the plurality of fibers.

A rope and a method of constructing the rope. The rope may be of 1212 braided construction and include a core for its length. The rope includes a plurality of primary strands, and each of the primary strands includes a plurality of fibers which may be made of a high-friction material. The rope also includes a secondary strand surrounded by the plurality of primary strands. The secondary strand includes a plurality of fibers which may be made of a low-friction material.

Disclosed is a method for producing a high strength synthetic strength member containing rope and a resultant rope that has greater resilience to high heat temperatures resultant of use with powered blocks and/or sheaves and has a longer service life in comparison to known synthetic rope constructions. The rope of the present disclosure has multiple distinct synthetic substances each forming distinct components that work together to, surprisingly, increase tolerance to bending fatigue of the rope and especially to high heat temperatures resultant of use with powered blocks and/or sheaves in comparison to known synthetic ropes.

An article containing an innerduct structure and a woven rope located within the innerduct structure. The woven rope an inner portion comprising a plurality of multifilament fibers in the length direction of the woven rope and a jacket portion covering the inner portion. The jacket portion contains a plurality of monofilament fibers in the length direction of the woven rope and at least one multifilament fiber in the circumferential direction interwoven with the monofilament fibers in the length direction of the jacket portion. The monofilament fibers of the jacket portion form the majority of the outer surface of the woven rope.
