Abstract
This application describes a braided cord containing a braided sheath and optionally a core surrounded by the braided sheath. The braided cord has changing cross-sectional area ranging from 0.0004 mm2 to 30 mm2 and contains one or more sections having a tapering angle ranging from 1° to 60° when observed in one direction along the cord axis. The change in the cross-sectional area of the cord can be achieved by changing the thickness of the braided sheath and/or changing the cross-sectional area of the core when the core is present. The thickness of the braided sheath can be adjusted by changing the size and/or twist level of one or more sheath strands, changing the pick count of the braided sheath, and/or using one or more shaped sheath strands. This application also describes a process of producing the braided cord with changing cross-sectional area.
