Abstract

The present invention relates to a method for improving image property of ink-jetting printing with Gemini compounds and belongs to the technical field of textile chemistry. The present invention is characterized in that the method comprises the following steps: removing the residues on the surface of the textile fiber and then treating with sodium carbonate and peregal O solutions; immersing or padding finishing with impregnating solutions of Gemini cationic compounds; and then baking and ink-jetting printing. The Gemini quaternary ammonium salt finishing technology can improve the ink-jetting printed image property of textiles and increase the definition as well as the color depth and the brightness. The finished textiles have excellent color fastness and feel good. Besides, the method has the advantages of low fiber damage, zero sewage discharge, energy saving and high production efficiency and is worth of vigorous popularization.
