Today the multifunctional treatment of outer surface layer combining microporous coating and nanotechnology could provide immense potential for textile industry compared to existing technologies. It will be shown that using polyurethane (PU) microporous crushed foam coating and nanofinish spraying technique the synergistic effect between barrier and functional properties of textiles can be achieved. The foam is open cell selective barrier, which prevents penetration of particles and microbial agents. At the same time the outer PU layer accumulates higher amount of nanostructures such as silver and copper nanoparticles for antibacterial properties or conductive organic polymers nanoparticles for the electrostatic/electromagnetic protective properties. The main benefit of this surface treatment technology is reduced amount of chemicals, wastewater and energy consumption in comparison with conventional textile finishing technologies.
