附着有碳纳米管的导电纤维、导电纱、纤维结构体和它们的制造方法
摘要：
导电纤维，其包括：合成纤维与含有碳纳米管且被覆所述合成纤维的表面的导电层，其中所述导电层相对于所述合成纤维的整个表面的被覆率不小于60％(特别是不小于90％)。该导电纤维的电阻值为1×10-2～1×1010Ω/cm范围，且电阻值的对数的标准偏差小于1.0。所述导电层的厚度为0.1～5μm范围，且相对于所述合成纤维的100质量份，所述碳纳米管的比例为0.1～50质量份。所述导电层可进一步含有粘合剂。所述导电纤维可通过振动所述合成纤维的同时将所述合成纤维浸渍于所述分散液中以形成附着于所述合成纤维的表面的导电层来制造。该导电纤维使所述碳纳米管均匀且牢固地附着于它的几乎整个表面且具有导电性及柔软性。
摘要（英）：

Disclosed is an electroconductive fiber comprising synthetic fibers and an electroconductive layer covering the surface of the synthetic fibers and containing carbon nanotubes. Not less than 60% (particularly not less than 90%) of the total surface of the synthetic fibers is covered with the electroconductive layer, and the electric resistance of the electroconductive fiber is in the range of 1*10<-2> to 1*10<10> Omega/cm, and the standard deviation of the logarithm of the electric resistance is less than 1.0. The thickness of the electroconductive layer is in the range of 0.1 to 5 micrometers, and the amount of the carbon nanotubes may be 0.1 to 50 parts by mass based on 100 parts by mass of the synthetic fiber. The electroconductive fiber may contain a binder. The electroconductive fiber may be produced by immersing the synthetic fibers in a dispersion while applying vibration to the synthetic fibers to deposit an electroconductive layer on the surface of the synthetic fibers. In the electroconductive fiber, the carbon nanotubes are deposited evenly and strongly onto substantially the whole area of the surface of the fibers, and, thus, the electroconductive fiber is electroconductive and flexible.
