Abstract:
Provided are a core-sheath composite fiber, and a woven fabric and fisheries tool using the same, said core-sheath composite fiber having a core part formed from a thermoplastic resin A and a sheath part formed from a thermoplastic resin B other than the thermoplastic resin A, wherein the sheath part has an anchor part that extends to the inside of the core part in a cross-section of the composite fiber, and the anchor part forms an undercut shape having a wide part wider than the root part thereof. It is possible to select materials capable of expressing optimal characteristics according to application for each of the core part and sheath part, and minimize the amount of materials used for the for the sheath part, for which comparatively expensive material is required, thereby making it possible to manufacture the composite fiber inexpensively while giving the composite fiber as a whole superior characteristics.
