A fiber cord for reinforcing rubber includes an organic fiber covered with a resin for which the average integration value of hardness measured by AFM is 150 MPa or less. A fiber cord for reinforcing rubber which could not be achieved with prior art, can be achieved with improved initial adhesiveness and heat-resistant adhesiveness as well as excellent stress relaxation for the rubber-cord composite.

The present invention pertains to a friction transmission belt that includes a core cable. The core cable includes a cord comprising: a core yarn containing high elastic-modulus fibers; and a plurality of sheath yarns that are disposed around the core yarn and that contain low elastic-modulus fibers. The cord is twisted and the proportion of the average diameter of the sheath yarn to the average diameter of the core yarn is 0.2 to 0.4.

A reinforcing fiber bundle is a continuous reinforcing fiber bundle having a length of at least 1 m and is characterized by the number of monofilaments per unit width being at most 1,600/mm and the average number of fibers in the bundle being at most 1,000 in a region (I), and the drape level found in a region (II) being 120-240 mm. The continuous reinforcing fiber bundle has a length of at least 1 m and is characterized by the adhesion amount of a sizing agent (I) in the region (I) being 0.5-10% by weight and the drape level found in the region (II) being 120-240 mm. The continuous reinforcing fiber bundle has superior mechanical properties, formability into complex shapes, and continuous producibility.

A yarn includes elongated pieces of expanded graphite sheet and a tubular member made of knitted or braided fibers. In the tubular member, the pieces of expanded graphite sheet are twisted and packed. The yarns are knitted, or bundles of the yarns are twisted to form a gland packing.

A continuous wire that includes a wound inductance from a first yarn material formed of filaments or nanotubes, the first yarn being doped with or including a first material that causes it to be electrically conductive and a second yarn formed of material filaments or nanotubes that is electrically insulating and may include magnetic particles wound with the first yarn in bifilar fashion or both yarns wrapped in a bifilar fashion around an insulating core yarn which may include magnetic particles to increase the inductance of the wire. The doping and electrical conductance of the yarns can be varied along the length of the wire to integrate sections of lumped electrical conductance and inductance.

The present invention relates to a V-ribbed belt that includes carbon-fiber twisted cords as core wires, the V-ribbed belt having a tensile elasticity of 240-500 N/(mm.Math.%), and the core wire diameter of the core wires being 0.6-1.2 mm. The V-ribbed belt may have a tensile strength of 620 N/mm or more per 1 mm width of the belt.
