PROBLEM TO BE SOLVED: To obtain an electroconductive resin composition capable of manufacturing an electroconductive yarn with excellent mechanical strength and electroconductivity through its spinning process, by admixing a resin with fine electroconductive fibers made by coating a specific fibrous core material with an electroconductive matter. SOLUTION: This electroconductive resin composition is prepared by admixing a resin such as of polyester or polyamide with 5-85 wt.%, based on the resin, of electroconductive fibers made by coating an electroconductive matter consisting mainly of carbon or tin oxide on the surface of a fibrous core material 1-5μm in average fiber length, 0.01-0.5μm in average fiber diameter and >=3 aspect ratio consisting of e.g. potassium titanate of the formula mK2 O.nTiO2-x .yH2 O ((m) is 0 or 1; (n) is 1 or 4-8; (x) satisfies the relationship: 0<=(x)<2; (y) is 0-10; with the proviso that, when (m)=0, (n)=1, and when (m)=1, (n) is 4-8). The electroconductive yarn is obtained by spinning this resin composition. |
