vodivé vlákno (Au.,Cu.)

Conductive fibre based on gold (Au) and copper (Cu) is a specialised material designed for technical and smart textiles, where high electrical conductivity, chemical resistance, and the ability to integrate electronic functions directly into fabric are essential. Early ideas and experiments with metal fibres date back to the 19th century, with more intensive development in the 20th century alongside the rise of electronics. The most significant progress, however, has occurred in recent decades with the growth of smart textiles and electronic fabrics. Production involves forming very thin wires of gold or copper, which are further reduced to micro- or nanoscale dimensions and then integrated into yarns—either as standalone fibres or as coatings applied to other fibres through electroplating or chemical deposition. In many cases, fibres consist of a steel core coated with a thin layer of copper or gold, combining mechanical strength with excellent conductivity. In the textile industry, Au- and Cu-based fibres are used for antistatic fabrics, electromagnetic interference (EMI) shielding textiles, heating textiles, and sensor-enabled materials. They are applied in protective clothing, smart garments, medical wearables, and fashion designs with advanced functionality. These materials are a key component in the development of wearable electronics and the integration of technology into everyday clothing.
