Activated dye ink as well as preparation method and application thereof

Abstract

The invention discloses activated dye ink as well as a preparation method and application thereof. The activated dye ink comprises an activated dye, an adjuvant, a high-boiling-point solvent and water, wherein the adjuvant comprises a macromolecular thickener and a macromolecular surfactant with the molecular weight of 500 to 2,000; the use amount of the macromolecular surfactant is 0.1 to 5 percent, the use amount of the macromolecular thickener is 0.3 to 10 percent, the use amount of the activated dye is 3 to 15 percent, and the use amount of the high-boiling-point solvent is less than 25 percent but not 0; and the percentage is a percentage of the mass of each component in the total mass of the activated dye ink. The preparation method comprises mixing all the components and filtering the mixture. The activated dye ink disclosed by the invention is applied to a wet-printing digital printing technology, so that the phenomena of lines and burrs of wet-printing digital printing can be greatly reduced, the brightness of a textile, the clearness of a pattern and the color stability of textiles subjected to batch printing and dyeing are improved, and the problem of print permeability of a thick textile is effectively solved.

Description

technical field [0001] The invention relates to the field of digital inkjet printing, in particular to a reactive dye ink and its preparation method and application. Background technique [0002] Digital printing technology is an emerging green printing technology that emerged in the 1990s. In small-batch textile printing, it has the characteristics of fast, high efficiency and low cost. It is a new textile printing technology vigorously advocated and supported by our country. As one of the industries supported by the state, textile digital inkjet printing technology has been widely promoted and used all over the world relying on its obvious green printing technology and unique printing method. [0003] The traditional textile digital inkjet reactive printing technology has been widely promoted and used in thin textiles such as silk, silk scarves, and mercerized cotton, but it is difficult to obtain market approval for thick textiles, such as thick towels, bath towels, and b...
