Certain anionic polyurethanes are excellently suited for use as binding agents for coating, dyeing and printing textiles and leather. Said polyurethanes are biodegradable. The residual and wash liquors left over from the dyeing process can therefore be conveyed to a biological effluent treatment plant.
Certains polyuréthanes anioniques conviennent remarquablement comme liants pour l'enduction, la teinture et l'impression de textiles et de cuirs. Ces polyuréthanes sont biodégradables, de sorte que les bains résiduaires et détergents issus du processus de teinture peuvent être acheminés à une installation de clarification biologique.
