<p>PROBLEM TO BE SOLVED: To obtain a highly strong fiber rope having a high strength and excellent flexural fatigue resistance and suitable for rope ways by applying a specific twist coefficient ratio to a core strand and side strands comprising specific fibers having high strength and low elongation, impregnating the rope main body with a fluororesin and further disposing an outside layer on the impregnated rope main body. SOLUTION: This highly strong fiber rope is obtained by preparing a core strand 1 and side strands 2 surrounding the core strand 1 from high strength and low elongation fibers each having a breaking strength of >=20 g/d and an elastic modulus of >=500 g/d, such as aramide fibers, impregnating and baking the combination with a fluororesin such as tetrafluoroethylene polymer, applying twists to the resin-impregnated combination so as to satisfy the inequality: 1<K0 /K1 <=5.76, preferably 1.2<K0 /K1 <=55.0 (twist coefficient is TD<1/2> ; T is twist number/30 cm; D is fineness denier) to form a rope main body R, and subsequently disposing an outside layer 3 containing a knitted product comprising synthetic fibers such as polyester fibers, a thermoplastic resin layer such as a polyurethane resin layer, or both the materials on the rope main body.</p> |
