摘要

The rope (10) has cladding that is formed by sheath filaments (31-34), and core that is formed by an inner core thread (44) and outer core thread (43). The haptic threads (20) and thread forming filaments (41) fed within braided fabric structure of cladding or within core so as to surround core. The diameter of thread forming filament is set same as that of diameter of sheath filaments. The diameter of haptic thread is set greater than diameter of sheath filaments.
