    Abstract: A cord comprises a braided sheath of strands having an outer surface, an inner surface, and a central hollow portion defined by the inner surface and having a volume and a core within the central hollow portion of the tubular braided sheath, such that when the cord is in a relaxed state the tubular braided sheath has a cylindrical shape and a relaxed volume of the central hollow portion wherein the core does not fill the relaxed volume of the central hollow portion of the tubular braided sheath; when the cord is in a longitudinal tensioned state, the tubular braided sheath elongates under the longitudinal tension such that a tensioned volume of at least a part of the central hollow portion of the tubular braided sheath is less than the relaxed volume; and the inner surface of the tubular braided sheath of tensioned volume contacts and cinches a surface of the core.

    Abstract: Disclosed herein are methods for producing core-sheath structures by shaping at least one filament bundle containing a plurality of filaments to form at least one shaped strand of filaments, and braiding a plurality of strands, including the at least one shaped strand of filaments, over a core to form the core-sheath structure containing a braided sheath of the strands surrounding the core, wherein the shaped strand of filaments is an untwisted strand having a twist level of less than 1 turn per meter, a cross-sectional aspect ratio of the shaped strand of filaments is at least 3:1, as measured in the braided sheath, a thickness of at least a portion of the braided sheath ranges from about 10 to about 200 μm, and the braided sheath comprises a synthetic fiber having a tensile strength of greater than 12 cN/dtex. Also disclosed herein are core-sheath structures formed by such methods.

    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.
