Elektrisola Feindraht

Fine metal wires may be directly integrated into the fabric or yam stracture. In some applications, there is a need to insulate the wires. This can be achieved by the application of an insulated coating. For example, Elektrisola Feindraht (2014) markets enamelled copper wire with coatings of polyurethane, polyesterimide, poly-amidimide and polyimide. 

Swiss company Elektrisola Feindraht AG (Elektrisola, 2015) fabricates metal monofilaments that can be blended with all sorts of fibers or that can be directly used in weaving and knitting. Importantly, the material has different electrical properties (see Stoppa and Chiolerio, 2014). The products range from copper (Cu) and silver-plated copper (Cu/Ag) filaments, to brass (Ms) and silver-plated brass (Ms/ Ag) filaments, to aluminum (Al) filaments, to copper-clad aluminum filaments (Elektrisola, 2015).
