Abstract

The invention discloses ink jet printing reactive dye ink, a preparation method thereof and a printing and dyeing process of the ink, and belongs to the related technical field of ink jet printing. The ink jet printing reactive dye ink comprises, by weight, 4-20 parts of reactive dyes, 0.1-0.3 part of cationic modifiers, 0.4-2.5 parts of surface tension regulators, 10-40 parts of viscosity modifiers, 0.1-1.5 parts of pH (potential of hydrogen) modifiers, 0.2-1.2 parts of sterilizing agents, 3-11 parts of wetting agents, 1-3 parts of dyeing auxiliary, 2-5 parts of leveling agents, 1-10 parts ofsoftening agents and 40-80 parts of deionized water. According to the ink jet printing reactive dye ink, the cationic modifiers can be closely combined with ions in cotton fabrics to be printed and dyed, the apparent color yield of the fabric is improved, and the fixation rate of the fabric is increased.

Description

technical field [0001] The invention relates to the related technical field of inkjet printing, in particular to an inkjet printing reactive dye ink, a preparation method thereof and a printing and dyeing process. Background technique [0002] Compared with traditional printing technology, inkjet printing technology has developed very rapidly due to its obvious technical advantages. Among them, reactive dye inkjet printing ink is the main consumable material for printing and dyeing production using inkjet printing technology. Due to its high price, it has become a technical bottleneck for the large-scale application of inkjet printing technology. [0003] In addition, the color fixation rate of existing inks in the inkjet printing process is generally not high. This factor directly leads to the problem of color fading in the subsequent washing process of fabrics. Fading not only causes waste of dyes, but also pollutes water bodies. . [0004] In order to reduce the fading ...
