Abstract

The invention discloses a preparation method of pigment ink for inkjet printing of a non-adhesive textile, and belongs to the technical field of fine chemical engineering and material science. Different from the conventional ink for inkjet printing, the ink is obtained by adopting ultrafine coated pigment color paste obtained by a miniemulsion polymerization method as a coloring agent, adding substances such as a water-soluble cosolvent, a surface active agent and deionized water, stirring, mixing and filtering. The ink does not contain the adhesive, has the advantages of small particle diameter, high storage stability and good jetting smoothness and the like; and the inkjet printed textile prepared by the ink has the advantages of good color fastness and color brightness and good hand feel.

Description

technical field [0001] The invention relates to a preparation method of pigment ink for ink-jet printing of adhesive-free textiles, belonging to the fields of fine chemical industry and material science. technical background [0002] Inkjet printing is to input the required pattern into the computer through digital input, and after the computer color separation and drawing process, the inkjet printing machine is driven by the special computer software to print the ink directly on the textile, and it is completed after certain post-processing. printing process. Compared with traditional printing technology, inkjet printing technology has the characteristics of high product quality, low energy consumption and low pollution, and is the main development direction of the printing field in the future. Ink is an important consumable for inkjet printing, and the quality of inkjet printed fabric is closely related to the quality of its ink. Therefore, the development of inkjet prin...
