摘　　要：为了运用针织导电织物作为柔性传感器来测试肘部弯曲度,对不同工艺条件下的导电织物进行了传感性能测试,以期获得最佳织物工艺。针对不同原料、组织和织物密度设计了三因素三水平正交实验,在圆机上织制了9种规格的导电织物并制作成袖套,测试了人体实际穿着时肘部弯曲过程中导电织物电阻的变化,采用多指标极差法和SAS方差法综合分析了9种导电织物的线性度、稳定性和灵敏度。实验结果表明,影响传感性能的因素从大到小顺序为原料、组织、织物密度,地纱原料的弹性对各传感性能影响最大,所以可以优先选择改变原料的弹性来调整传感器的传感性能。In order to use knitted conductive fabrics as flexible sensors to test elbow bending, the sensing properties of conductive fabrics under different processing conditions were tested to obtain the best fabric process. Three-factor and three-level orthogonal experiments were designed for different raw materials, weaves and fabric densities. The conductive fabrics of nine specifications were woven on the circular machine and made into sleeves to test the resistance changes of conductive fabrics during elbow bending in practice. The linearity, stability and sensitivity of nine kinds of conductive fabrics were comprehensively analyzed by multi-index range method and SAS variance method. The experimental results show that the order of factors affecting the sensing performance of sensors is: raw material>weave>fabric density. The elasticity of ground yarn material has the greatest influence on the sensing performance. Therefore, it is preferable to change the elasticity of raw materials to adjust the sensing performance of the sensor.
