This paper presents aspects concerning the life cycle assessment of the electroconductive textile functionalized by advanced RF plasma technology based on argon and oxygen gases and deposition of the metallic micro/nanoparticles. In order to obtain the textiles with electroconductive properties, the preliminary plan consisted functionalization of the textiles by using RF plasma technology based on argon and oxygen gases and processes for micro/nanoparticles deposition such as foulard, direct printing, and thin film position. It was analyzed the life-cycle inventory (LCI) and was provided the study for life-cycle assessment (LCA) using SimaPro software and Eco-indicator 99. In order to obtain the LCI, we used to input and output technical data, from the plasma process, and the SimaPro software for generating the LCI and LCA. The input data about raw material, energy, chemical substances, have been collected by direct measurements on machinery, device log, and specifications of the equipment (technical books) and processes. The output data was obtained using SimaPro software connected to internet-specific databases. The purpose of our research has been to study the life cycle assessment of the electroconductive textiles functionalized by RF plasma technology in comparison with classical functionalization treatments.
