PURPOSE:To provide the subject fiber developing no wear due to fraction with metallic parts, easy to produce, and improved in whiteness. CONSTITUTION:The objective conjugate fiber made up of (A) an electrically conductive component consisting of a thermoplastic polymer incorporated with 3-45wt.% of electrically conductive carbon black, (B) a protective component consisting of a fiber-forming thermoplastic polymer incorporated with 3-25wt.% of a white pigment, and (C) a coating component consisting of a water-soluble polyester polymer, where at least part of the component A is exposed on the surface of the component B and both the components A and B are entirely coated with the component C at a thickness of 0.5-15mum. The component C consists of a polyester prepared by copolymerization between (1) terephthalic acid, isophthalic acid, SO3M-bearing dicarboxylic acid, alicyclic dicarboxylic acid and/or ester-forming derivative(s) therefrom and (2) a diol component like ethylene glycol, neopentyl glycol or diethylene glycol. |
