Electroconducting fibers

The mechanical properties of a conductive material play an important role when selection is performed for any particular textile application. Metallic filaments usually compromise good electroconductive characteristics with poorer mechanical properties. A very high stiffness and lower stretchability of metallic fibers not only makes the woven or knitting process difficult but also reduces their service life. On the other hand, polymeric fibers or yams exhibit good elongation and recovery properties. The combination of nonstretchable metallic fibers with stretchable polymeric yams creates a new class of metal-based electroconductive fibers, which is known as co-spun polymeric-metal yams (Fig. 28.3). 

All polymer electroconductive fibers can be obtained by blending ICPs with common polymers. At our in-house Smart Textile facilities we produced PP/PANI and PP/ PA/PANI composite fibers. Pig. 28.7. The production of these fibers involved two steps compounding and spinning. For fiber spinning, the melt spinning process is the most suitable method. The ICP-based electroconductive fibers we have produced...

An electroconductive aramid paper can be made by the addition of a conductive filler, such as carbon fiber [46]. The paper should also have a certain level of surface resistivity to avoid the buildup of charge and provide an optimum electrical shielding.
