<p>PROBLEM TO BE SOLVED: To provide an extra-fine conductive composite fiber which has a long-term-stable static elimination effect, can improve cleanliness after wiping further and contributes to wiper production.SOLUTION: An extra-fine conductive composite fiber is a sheath/core type composite fiber comprising a sheath component composed of a crystalline thermoplastic polymer (B) and a core component composed of a conductive polymer (C) and has a single fiber fineness of 0.05-1.00 dtex and a flat cross section meeting condition a/b≥1.2, where 'a' is the length of the major axis of the fiber cross section and b is the length of the minor axis.</p> |
