Decoration of insulating textile with electrically conductive nanoparticle has brought about a novel-application field for us. Nanoparticle-coated fabric can be used for different types of electronic purposes. In this work, cotton-based knitted and woven fabrics are coated with copper and silver nanoparticles simultaneously following a cheaper and easier dip and dry process with less chemical utilization. Cu and Ag nanoparticles are demonstrated using a highly reactive, cheaper, and available reducing agent. Our sample shows constant conductivity for about a few months in the open air. In addition, the change of resistance of the fabric with respect to bending is examined. Further, a simple LED circuit was integrated with the fabric to test the compatibility of the fabric for the application of wearable electronic textiles. This paper will provide a future direction to the researchers who would like to work with electronic textiles.
