摘要
为开发和拓展碳黑导电纤维的应用,利用体式显微镜和扫描电子显微镜对导电纤维的表面形态进行表征,测试了不同碳黑含量、不同线密度的导电纱线在标准环境下的电阻大小,并线性拟合了导电纱线电阻大小与测量长度的关系,对比分析了热定型温度和洗涤次数对纱线导电性能的影响。结果表明:碳黑导电成分在纤维表面,改善了锦纶纤维的力学性能;碳含量较高的纤维其导电性能优于碳含量较低的纤维,导电纱线电阻与它们的长度成正比,与截面成反比;锦纶导电纱的电阻值随着温度的升高而减小,纱线热处理温度不超过120℃;洗涤次数对锦纶导电纱线的导电性能影响小,纱线导电性能稳定。
In order to develop and extend the application of carbon black conductive fiber, the morphological structure of conductive fiber was characterized by stereo-microscopy and scanning electron microscopy, and the conductive resistances of conductive yarns of different carbon black contents and finenesses were tested under the standard normal atmospheric condition. The regression curves of the resistance of conductive yarns and the measuring length were drawn. The influences of heat setting temperature and washing times on the electrical properties of conductive yarns were analyzed and compared. The results show that carbon black on the surface of the fiber improves the mechanical properties of nylon fiber. The conductive properties of the fiber with higher carbon black content are better than that with low carbon black content. The resistance of conductive yarns is proportional to their length and inversely proportional to the cross section. The resistance value of the polyamide conductive yarn decreases with temperature. Yarn heat treatment temperature is not higher than 120 ~C. Almost no effect of washing times exists on the conductivity are stable. of conductive nylon yarn, and yarn conductive properties
