| Abstract: | This work deals with the preparation and characterization of electrically conductive textiles for heat generation. Needlepunched nonwoven, spunlace nonwoven, and woven fabrics, all made of 100% polyester fibers, were made electrically conductive by in situ chemical polymerization of pyrrole with p-toluene sulfonic acid dopant. Alkali hydrolysis of polyester fabrics was done before in situ polymerization for better fixation of polypyrrole on polyester. The average surface resistivities were found to be 1013.08, 1099.72, and 1434.12?Ω/□, respectively, for needlepunched, spunlace, and woven fabrics. The electro-conductive fabrics displayed exponential rise of surface temperature on application of voltage and the rise of temperature was found to be related to the time duration of applied voltage. The electro-conductive fabrics exhibited linear voltage–current relationship at low voltage range. The surface resistivity of the electro-conductive fabrics was increased substantially on prolong exposure to atmosphere. |
