This study developed electroconductive textiles by coating polypyrrole to PET nonwoven-based Polyvinyl Alcohol (PVA) nanoweb made by electrospinning and applying the developed electrotextiles as ECG Electrodes. To find the optimum coating conditions for high electrical conductivity, the ratios of 2.6-Naphthalenedisulfonic acid with Disodium Salt (NDS) vs Ammonium Persulfate (APS) as an oxidant and a doping agent in the solution were changed from 3:7 to 7:3; the immersion time of the specimen in the solution was 1 hour. PVA nanowebs coated with polypyrrole under various conditions were filmed with FE-SEM. FT-IR analysis was also performed to examine the presence of polypyrrole nanoparticles in the PVA nanoweb. The electrical resistance of the treated specimens were measured with a Multimeter. Consequently, the PVA Nano Web was undamaged even after heat treatment that allowed for coating. Uniform polypyrrole nanoparticles then formed on the surface of the PVA nanoweb after coating. The measured electrical resistance was shown to be at least $12K{\Omega}/{\Box }$ from a maximum of $3,456K{\Omega}/{\Box }$. The proper amount of NDS content had a positive effect on the conductivity improvement of electroconductive textiles; in addition, the highest electrical conductivity was achieved with a ratio of 3:7 between NDS and APS.
