Abstract
Provided is a double braid rope structure which is provided with an inner core and an outer cover. In the double braid rope structure (10), the inner core (3) includes high strength and high modulus fibers with a yarn tenacity of 20 cN/dtex or higher and a yarn elastic modulus of 400 cN/dtex or higher, and has a ratio of yarn length/rope length of 1.005 or more and 1.200 or less, the rope length being determined as a length of a cut section (V) cut to a certain length from the rope structure (10), and the yarn length being determined as an average value of lengths of yarns constituting the inner core of the cut section (V).
Claims11
A double braid rope structure comprising an inner core and an outer cover, wherein the inner core comprises high strength and high modulus fibers with a yarn tenacity of 20 cN/dtex or higher and a yarn elastic modulus of 400 cN/dtex or higher, and has a ratio of yarn length/rope length of 1.005 or more and 1.200 or less, the rope length being determined as a length of a cut section cut to a certain length from the rope structure, and the yarn length being determined as an average value of lengths of yarns constituting the inner core of the cut section.
A double braid rope structure comprising an inner core and an outer cover, wherein the inner core comprises high strength and high modulus fibers with a yarn tenacity of 20 cN/dtex or higher and a yarn elastic modulus of 400 cN/dtex or higher, and has a ratio of yarn length/rope length of 1.005 or more and 1.200 or less, the rope length being determined as a length of a cut section cut to a certain length from the rope structure, and the yarn length being determined as an average value of lengths of yarns constituting the inner core of the cut section, wherein the outer cover substantially comprises non-high strength and non-high modulus fibers.
A double braid rope structure comprising an inner core and an outer cover, wherein the inner core comprises high strength and high modulus fibers with a yarn tenacity of 20 cN/dtex or higher and a yarn elastic modulus of 400 cN/dtex or higher, and has a ratio of yarn length/rope length of 1.005 or more and 1.200 or less, the rope length being determined as a length of a cut section cut to a certain length from the rope structure, and the yarn length being determined as an average value of lengths of yarns constituting the inner core of the cut section, wherein both the inner core and the outer cover are braided bodies.
