The flexible conductive material is concentrated on the blending research of the coating type conductive material, the metal fiber and the common fiber, not only has requirements on the softness, comfort and other performances of the fabric, but also needs the fabric to have certain elasticity and elastic recovery performance. At present, common raw materials of the conductive yarn are to combine conductive metal filaments or short wires in a blending or cladding mode, so that good conductive performance is obtained. The general method is to use stainless steel wires or copper wires as core yarns and wrap other fibers to prepare conductive yarns.
