Abstract

An inkjet ink, a method for preparing the same and use thereof are described. The inkjet ink includes the following components in mass percentage: 5%-15% of a reactive dye, 15%-40% of a polyol, 2%-35% of an auxiliary agent, and remaining amount of water, wherein the reactive dye is selected from at least one of a dye with bifunctional reactive groups and a dye with trifunctional reactive groups. The described reactive dye in the inkjet ink has high reactivity, can react with a fabric and firmly adhere to the fabric, with the color fixation rate as high as 90-95%, good color fastness, less unfixed dye, and good storage stability. The described inkjet ink only needs to be washed with cold water or warm water to remove a primer during post-processing, and the washing period is short, and it can meet the requirements of clothing use even without washing by water.
