摘　　要：为开发柔性传感器用高性能导电纱,文章采用包缠工艺将不锈钢丝与桑蚕丝进行包覆,制备了8种不锈钢丝/桑蚕丝复合导电纱,研究了芯纱、外包纱规格对复合导电纱的表观形态结构、力学性能和表面摩擦性能的影响,并通过测量定速拉伸过程中电阻的变化分析其导电性能。结果表明:在制备的8种复合导电纱中,直径为0.035 mm不锈钢丝与88.9 dtex桑蚕丝包覆得到的复合导电纱条干均匀度最好,复合导电纱的断裂强度较好,表面摩擦系数最小,灵敏度最大。综合分析复合导电纱的各项性能,得出直径为0.035 mm不锈钢丝与88.9 dtex桑蚕丝包覆得到的导电纱性能最好。In order to develop the high-performance conductive yarn used for the flexible sensor, eight kinds of stainless steel wire/silk composite conductive yarns were prepared by wrapping technology. The effects of core yarn and cladding yarn specifications on the apparent morphology, mechanical properties and surface friction properties of the composite conductive yarns were studied and the conductivity was analyzed by measuring resistance changes in the process of constant-speed stretching. The results show that among eight kinds of composite conductive yarns, the composite conductive yarn coated by the stainless steel wire with diameter of 0.035 mm and 88.9 dtex silk has the best yarn evenness. In addition, the breaking strength is good, the surface friction coefficient is the lowest, and the sensitivity is the best. By synthetically analyzing the properties of composite conductive yarn, it is concluded that the composite conductive yarn coated with 0.035 mm stainless steel wire and 88.9 dtex silk has the best properties.
