A novel coating method (dissolving-coating method) is designed to provide electrically conductive fibers with lower electrical resistivity and permanent conductivity. In the dissolving-coating method, no adhesive was used, but a solvent of fiber substrate was used. Carbon black (CB)-coated polycaprolactam (PA6) fibers application for electrically conducting sensor were prepared by the new coating method. The durability of CB coatings on PA6 fibers was tested through washing and stretching test. To make a study on the electromechanical behavior of the CB-coated PA6 fibers under tensile load, the effects of various factors that are responsible that correlates the resistance change with the applied strain, strain rate (S.R), the environmental temperature, and the relative humidity (RH) were discussed.
