These fabrics were chemically oxidized by FeCl3 in water. Polypyrrole has been found incorporating into interior of fibers and spacing between fibers. The resistivities of polypyrrole and nanoparticles contained fabrics were lower than those of fabrics containing polypyrrole(30 to 100 Ω/square). The existence of metal nanoparticles in fabric was identified by atomic absorption spectroscopy and electron dispersive spectroscopy. Gold loading of the conductive fabric was high comparing to two other metals. Dispersion of preadsorbed metal nanoparticles on the surface of fibers of pristine fabric was good according to images taken from electron scanning microscope. Electromagnetic shielding of the conductive fabrics were significant 8-26dB(nylon 6)、7-15dB(PET) and 5-9dB(cotton)，although resistance of polypyrrole lose during laundry was fair for above textiles.
