Providing a substrate, treating the substrate with an aqueous coating formulation comprising a cationic polymer or copolymer, a fabric softener, and an aqueous absorption solution of urea or an aqueous absorbent solution of urea or ammonium sulfate, selected from sodium bicarbonate, sodium carbonate or a combination thereof Treating the substrate with an absorbent solution, drying the substrate, printing the substrate with a reactive or acidic dye-based ink, and post-treating the printed substrate, depending on the coating or post-treatment printed substrate. A method of making a printed substrate, to improve adhesion, dye fastness, and wash fastness of a reactive or acidic dye-based inkjet ink printed on the substrate.n n n n Cationic Polymer, Inkjet, Printing, Textile, Coating, Color Fastness |
