A method of manufacturing a core-sheath structure is disclosed by shaping at least one tow comprising a plurality of filaments to form a strand of at least one shaped filament, and weaving a plurality of strands comprising the strand of at least one shaped filament on a core to form a core-sheath structure comprising a woven sheath surrounding the strand of the core, wherein the strands of the shaped filament are untwisted strands having a twist of less than 1 twist per meter, the cross-sectional aspect ratio of the strands of the shaped filament measured in the warp knitted sheath is at least 3: 1, the thickness of at least a portion of the warp knitted sheath ranges from about 10 to about 200 [mu] m, and the warp knitted sheath comprises synthetic fibers having a tensile strength of greater than 12 cN/dtex. Also disclosed herein are core-sheath structures formed by such methods. 本发明公开芯-鞘结构的制造方法，方式是将至少一个包含多个丝的丝束成型以形成至少一个成型的丝的线股，并且在芯上编织包括至少一个成型的丝的线股的多个线股以形成包含围绕芯的所述线股的经编织的鞘的芯-鞘结构，其中成型的丝的线股为捻度小于1捻回数/米的未捻线股，在经编织
