Smart options for pigment printing and multifunctionalization of wool and polyester/ wool blended fabrics in single step

This research work was aimed to produce multifunctionalized wool and polyester/ wool pigment prints in one step process by individually incorporating TiO2-nanoparticles (TiO2-NP's, 10g/Kg), silicon micro-emulsion (20g/Kg) or a water/oil-repellent agent (40g/Kg), in pigment printing paste [pigment color (20g/kg); synthetic thickening agent (20g/kg); binder (100 g/kg); crosslinking agent (10g/kg); ammonium persulfate (NH4)2S2O8 (2g/kg)] followed by printing and microwave fixation at 1300W/4 min. The antimicrobial properties, UV-protection, soft-handle or water/oil-repellency along with printing properties were evaluated as well as the depth of the obtained functionalized pigment prints.
