In recent years, the use of electrical heating garments was dramatically intensified because of their wide range of application in different industries. One of the common ways to produce these textiles is integration of heating elements in fabric. Taking into account this conditions, in this research 8 groups of three-layer heating fabrics were produce using different weave pattern on the front and back layers, two levels of weft to heating element ratio and two warp ratio of back and front layer. The mentioned three layer fabrics were warp stitched woven fabrics in which the heating element (tungsten) was embedded in the middle layer as wadded weft. In order to report the heat performance of fabrics, thermal parameters such as the heat flux under two different voltages and at different sides of the fabrics were evaluated by using flux meter sensor. Moreover, this sensor was situated at different positions in relation to the fabric, in order to simulate various functional conditions of the heating fabric. According to the results, the voltage, ratio of weft to element and ratio of warp yarns in front and back layer, had significant influence on the measured heat flux. On the other hand, the weave pattern and technical side of the fabric did not have significant effect on the heat flux.
