Conductive fibres and Conductive yarns have drawn considerable attention during the last decade. Generally speaking, textile materials made of organic polymers are perfect insulators. Due to weak electrical conductivity electrical load is accumulated on the surface of organic polymers. Therefore, to prevent the accumulation of electrical load, to enhance the possibility of electrical load transfer and to obtain electromagnetic shielding effect, the textile materials are turned into electrically conductor by using different methods.
Methods of producing conductive yarns can be summarized as follows:
Adding carbon or metals in different forms such as wires, fibres or particles (eg. core spun, blends)
Using inherently conductive polymers
Coating with conductive substances
Adding carbon or metals in different forms such as wires, fibres or particles:
It is possible to obtain textiles with conductive property by inserting carbon or metals such as silver, steel, nickel to the structure, in the form of wires, fibres, and micro or nano particles. Carbon fibres and carbon filled fibres exhibit good conductive properties, but on the other hand, they have some aesthetic problems.
Metal fibres can be produced by using bundle-drawing process or s process. Metal fibres and wires which can be incorporated into textile structures have high conductivity, but they have also some disadvantages like their weight, cost and the damage which they can give to the textile machinery.
