Abstract:
1. A rope ( 1 ) having a core ( 11 ) and a casing ( 10 ) surrounding the core ( 11 ), the core ( 11 ) being of a multitude of synthetic fibers ( 110 ) and the casing ( 10 ) being of a multitude of synthetic yarns ( 100 ) interlaced with one another, the rope ( 1 ) comprising the synthetic yarns ( 100 ) forming the casing ( 10 ) composed of polytetrafluoroethylene (PTFE) and forming a lightproof and fluid-repellent envelope for the core ( 11 ), the synthetic yarns ( 100 ) that form the casing ( 10 ) are each of a multitude of individual PTFE fibers twisted together, and the synthetic fibers ( 110 ) composing the core ( 11 ) are each individually twisted with 200 to 700 turns/m in a first rotation direction around a longitudinal axis and then a plurality of the twisted synthetic fibers ( 110 ) are twined together with 100 to 200 turns/m in the opposite rotation direction around the longitudinal axis.
