ANTISTATIC FIBER EXCELLENT IN WHITENESS

摘要

PROBLEM TO BE SOLVED: To provide an antistatic fiber excellent in whiteness that exhibits a high antistatic performance irrespective of the ambient humidity.SOLUTION: The core-sheath combined filament yarn is an antistatic fiber including a filament A1 containing 1-40 wt.% of a conductive material as a core part and a filament B2 having a fiber diameter of 10-1000 nm as a sheath part. In a fiber cross section, a thickness 3 of a sheath yarn layer composed of the filament B2 is 3-500 times of a fiber diameter of the filament B2. It is preferable that the conductive material which the filament A1 contains is conductive carbon black.
