The binding tape includes a substrate layer of a nonwoven fabric and an adhesive layer that contains an adhesive and that is provided on at least either surface of the substrate layer, where: the nonwoven fabric is formed from fibers at least partially containing a thermoplastic elastomer; and the nonwoven fabric has a tensile breaking strength in the tape longitudinal direction (A1) of 20 N/10 mm or more.

Abstract: A binding tape which has sound deadening properties, can suppress layer separation, and is also excellent in abrasion resistance. The binding tape includes a substrate layer made from a non-woven fabric, and an adhesive layer, wherein the substrate layer includes at least two types of fused sections having different shapes. The fused sections are preferably formed by thermally fusing fibers of the non-woven fabric by a heat embossing. Further, the binding tape preferably has a scrape abrasion resistance repetition number of 100 times or more.

Abstract: An optical drop cable includes optical fiber cores, tension-resistant members, and a single-material outer sheath covering the cores and the tension-resistant members. The bark of a young tree has elasticity, so that if cicadas lay eggs in the bark, the holes in which eggs are laid close and the eggs will not hatch. Cicadas cannot stick their ovipositors into bark having abrasion resistance. Thus, the outer sheath is made of polyurethane resin having rebound resilience equivalent to that of the bark of a young tree, and having high abrasion resistance. By making the outer sheath from such resin having elasticity and abrasion resistance, holes in which eggs are laid close, thus making hatching of the eggs impossible, or cicadas cannot stick their ovipositors into the outer sheaths. Black cicadas will therefore not lay eggs in the outer sheath, preventing damage to or breakage of the optical fiber.

Abstract: The object is to prevent damage to or breakage of optical fiber cores 11 due to the cable getting stuck with ovipositors of black cicadas. An optical drop cable 10 is proposed which includes optical fiber cores 11, tension-resistant members 12, an outer sheath 15 made of a single material and covering the cores 11 and the tension-resistant members 12. The bark of a young tree T has elasticity, so that if cicadas lay eggs in such a bark, the holes in which eggs are laid closes and the eggs will not hatch. If such a bark has abrasion resistance, cicadas cannot stick their ovipositors into the bark. Thus, the outer sheath 15 is made of a polyurethane resin having a rebound resilience equivalent to that of a bark of a young tree, and having high abrasion resistance.
