Title:

CONDUCTIVE COMPOSITE FIBER

Document Type and Number:

WIPO Patent Application WO/2019/065681

Kind Code:

A1

Abstract:

Provided is a conductive composite fiber formed from a polymer containing conductive carbon black in a polyamide resin as a conductive layer and thermoplastic resin as a nonconductive layer, wherein the conductive layer is exposed in three or more locations on the outside surface of the fiber in a cross section, the coefficient of variation (CV %) in the surface area of each conductive layer in a fiber cross section is 10% or less, and the average value of the area specific resistance is 4 log (Ω∙cm). It is possible to provide a conductive composite fiber wherein the variation in the fiber surface specific resistance is suppressed and the variation in the exposed surface area of each conductive layer polymer in a fiber cross section is suppressed by exposure of the conductive layer in three or more locations on the fiber surface, crimping of the original yarn is suppressed by equal disposition, and antistatic performance for woven and knitted fabrics and carpets is improved.
