摘要
以发热功率密度和温度均匀系数为指标,基于正交试验方案,探讨以不锈钢纤维纱为电加热元件的电加热机织物制备工艺。并基于九宫格取点法,优化温度均匀系数测试方法。研究发现:本研究中,温度测点取81点是可信的均匀度评价方案。电加热机织物的纬纱排列规律为1根不锈钢纤维纱+3根黏胶纱、纬纱密度为10.5根/cm、组织结构为经二重1/7时,织物具有较为优异的发热性能,发热功率密度为857.23 W/m^(2);电加热机织物的纬纱排列规律为1根不锈钢纤维纱+5根黏胶纱、纬纱密度为6.5根/cm、组织结构为经二重1/3时,电加热机织物具有较为优异的发热均匀性。
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/m^(2).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.
