丝/毛混纺纱的导电处理及性能研究
|
摘要
开发智能纺织品是传统纺织产业升级的途径之一,以导电纱线制备导电织物是最为常见的一种,文章采用聚吡咯导电高分子材料进行导电纱线的制备开发。以丝/毛混纺纱为纱线原料,氯化铁为氧化剂、吡咯为导电材料,制备丝/毛/聚吡咯复合导电纱,分析不同反应温度对复合导电纱线性能的影响。实验结果表明:复合导电纱线的电导率随着反应温度的降低而增加,反应温度为-5℃时,纱线的导电效果最好,电导率为8.32×10~(-2) S/cm,断裂强度为(35.18±0.16) cN/dtex,断裂伸长率为11.13%±0.83%,导电处理对纱线力学性能的影响不明显。
The development of smart textiles is one of the ways to upgrade the traditional textile industry. Producing conductive yarns with conductive fabrics is the most common way. In this paper, polypyrrole conductive polymeric materials were used to prepare conductive yarns. Silk/wool blended yarn was used as raw materials, FeCl_3 was used as the oxidant and pyrrole was used as conductive material to prepare silk/wool/polypyrrole composite conductive yarns. The effects of different reaction temperatures on the performance of composite conductive yarn were analyzed. The experimental results showed that the conductivity of the composite conductive yarn increased with the decrease of the reaction temperature. When the reaction temperature was-5 ℃, the conductive effect of yarns was the best, and the conductivity was 8.32×10~(-2) S/cm. The breaking strength was(35.18±0.16) cN/dtex, and the elongation at break was 11.13%±0.83%. The effect of conductive treatment on the mechanical properties of the yarn was not obvious.
