However, since the fiber containing carbon black exhibits a black color, there is a drawback in that even if added in a small amount, the aesthetic appearance of the fiber product is significantly impaired. This has a core-sheath structure in which a conductive component is a core and a protective component (non-conductive component) is a sheath, and further, a hollow portion is formed in the sheath component (JP-A-56-20614).

The conductive component is composed of a thermoplastic polymer and conductive carbon black uniformly mixed according to a conventional method. The mixing ratio of the conductive carbon black varies depending on the type of polymer and carbon black used, but is usually 3 to 45% by weight, and particularly preferably 5 to 35% by weight. If it is less than 3% by weight, sufficient conductivity as an electrically conductive fiber cannot be obtained, and it is difficult to mix it in an amount of 45% by weight or more. Even if it is mixed, it has very poor fluidity and often causes problems in spinning.

It is important that the coating component is easily soluble in an alkaline aqueous solution. In particular, when polyester is used as the conductive component and the protective component, it is necessary that it is more easily soluble in an alkaline aqueous solution than these. Examples of polyesters having such properties include polyesters obtained by copolymerizing a dicarboxylic acid component composed of terephthalic acid, isophthalic acid, and a dicarboxylic acid having a sulfonate with a diol component of ethylene glycol or polyethylene glycol. For example, copolymers of isophthalic acid / terephthalic acid / ethylene glycol with 5-sulfoisophthalic acid or a metal salt thereof (sodium and potassium salts) in an amount of 2.5 mol% or more, preferably 3.3 mol% or more, A copolymer of 6% by weight or more of polyethylene glycol is suitable because it is extremely soluble in an alkaline aqueous solution.

The conductive component (a), the protective component (b), and the coating component (c) are those obtained by combining a and b so that at least a part of the a component is exposed on the surface, and further complete with c. It is important to compound so that it is encapsulated in.

In the composite form of a and b, it is important that a is exposed on the surface of b. Examples of such a composite structure include the circular cross section shown in FIGS.
A non-circular shape as shown in FIG. 6 can be mentioned. The composite ratio of a and b is in the range of 5/95 to 30/70 in a / b volume ratio,
Particularly, the range of 7/93 to 20/80 is preferable. When the amount of the conductive component is large, it becomes difficult to form a fiber, and when the amount is small, the conductivity may decrease or disappear during spinning / drawing. As shown in FIG. 7, a having a formed inside the fiber is inferior in antistatic property because a, that is, the conductive component is not exposed on the surface of the fiber even if c is dissolved and removed with an alkaline aqueous solution.
