Based on orthogonal test scheme,the preparation technology of electric heating woven fabric with stainless steel fiber yarns as electric heating element was studied,taking the heating power density and the temperature uniformity coefficient as indexes.The testing method of temperature uniformity coefficient was optimized based on the point taking method of nine grids.The results showed that in this study,the number of temperature measurement points at 81 was a reliable uniformity evaluation scheme.When the weft arrangement of the electric heating woven fabric was one stainless steel fiber yarn and three viscose yarns,the weft density was 10.5 wefts/cm,and the structure was warp double 1/7,the fabric had excellent heating property,and the heating power density was 857.23 W/m2.When the weft arrangement of the electric heating woven fabric was one stainless steel fiber yarn and five viscose yarns,the weft density was 6.5 wefts/cm,and the structure was warp double 1/3,the fabric had excellent heating uniformity.
