Development and Characterization of Electric Heating Fabric Based on Silver Coated Nylon Yarn

Abstract

Due to the recent development of wearable electronic textiles and smart textiles, the conductive fabrics and electrically heated garments have been extensively studied and applied in many fields. In this work an electric heating fabric was fabricated by sewing silver coated nylon yarn over the polyester fabric. In order to minimize the power consumption, instead of heating whole garment surfaces, local warming was preferred by stitching silver coated nylon yarn over polyester fabric in a specific pattern. The integration of silver coated nylon yarn and portable power supply used for warming function. The heating fabric properties such as power supply and saturation time for a particular temperature were investigated. The results showed that the increase in temperature above room temperature was 16˚C and the power requirement for 1˚C rise in temperature was 0.92 Watts.
