A similar trend is observed where nano copper oxide is applied in combination with Acrylic binder. There is increase in the crease recovery angle which is higher than the samples that were only treated with nano copper oxide which may be attributed to the fact that more amount of cross linking takes place in the presence of binder than without it.
