Finishing method for reactive dye inkjet printing based on the cationic modifier ink

A finishing method for reactive dye inkjet printing based on a cationic modifier ink, comprising:

• inkjet printing the cationic modifier ink and a reactive dye ink in one step onto a pattern area of a cellulose fiber fabric subjected to a sizing treatment by an inkjet printing method to obtain a printed cellulose fiber fabric;
• and performing a steaming treatment or a baking treatment on the printed cellulose fiber fabric to obtain a reactive dye inkjet fabric;
• wherein
• a timespan of the inkjet printing the cationic modifier ink and inkjet printing the reactive dye ink is 0-2 min;
• the cationic modifier ink is an ink containing 1.0 wt %-60.0 wt % of a cationic modifier;
• the cationic modifier is one selected from the group consisting of 2,3-epoxypropyltrimethylammonium chloride, 2,3-epoxypropyltriethylammonium chloride, 3-chloro-2-hydroxypropyltrimethylammonium chloride, 3-chloro-2-hydroxypropyltriethylammonium chloride, monochlorotriazine-type quaternary ammonium salt compound, azetidine cation compound, and choline chloride;
• and
• a reactive dye used in the reactive dye ink is monochlorotriazine, dichloromestriazine, or a vinylsulfone type reactive dye.
