ELECTRIC CONDUCTIVE FIBER

摘要

PROBLEM TO BE SOLVED: To obtain an electroconductive fiber having a short half life and a low voltage in a frictional electric charge and suitable for a cloth such as a sweater by imparting a compound containing a polyether on the surface of the electroconductive fiber having a electric conductivity at a specific value or higher. SOLUTION: This electroconductive fiber is obtained by imparting 1-20wt.% compound containing a polyether structure on the surface of an electroconductive sheath core composite fiber of which sheath part of a core part consisting of an acrylonitrile- based polymer, is arranged in a cross sectional ratio of (5/95)-(60/40), containing 15-70vol.% electroconductive fine particles such as titanium oxide having >=10<-3> s/cm resistivity and <=3μm mean particle diameter in the core part, or another electroconductive fiber having >=10<-6> s/cm electroconductivity obtained by forming a membrane of a metal or a metallic compound such as copper sulfide and copper iodide having 0.1-10μm membrane thickness on the surface of the fiber. The compound containing the polyether structure is obtained by reacting a compound obtained by reacting an alkyleneoxide adduct polyetherpolyol with a polyvalent isocyanate compound and blocking the unreacted isocyanate groups with a compound obtained by reacting a polyetherpolyol with an epihalohydrin.
