Problems solved by technology

However, although the reactivity of the KN-type dyes in this scheme is higher than that of the existing K-type reactive dyes, the KN-type dyes are still single-active reactive dyes, and their color fixation rate is limited.

Abstract

The invention discloses ink-jet ink and a preparation method and application thereof. The ink-jet ink comprises the following components in percentage by mass: 5-15% of reactive dye, 15-40% of polyol, 2-35% of an auxiliary agent and the balance of water. The reactive dye comprises at least one of a dye with double active groups and a dye with three active groups. The reactive dye in the ink-jet ink is high in reactivity, can react with a fabric and is firmly attached to the fabric, the fixation rate reaches 90-95%, and the ink-jet ink is high in color fastness, little in flooding and high in storage stability. The ink-jet ink provided by the invention only needs to wash off slurry with cold water or warm water during post-treatment, the water washing time is short, and the use requirements of clothes can be met even without water washing.

Description

technical field [0001] The invention relates to the field of material technology, in particular to an inkjet ink and its preparation method and application. Background technique [0002] The printing technology of cotton, rayon and blended fabrics using reactive inkjet inks has been developed for many years. The typical production process is to pretreat the fabrics with high-viscosity anti-seepage slurry, and then use the reactive inkjet inks to be patterned by the printer. After drying, the reactive dyes react chemically with the fabric by steaming, and then wash to remove the unfixed reactive dyes and paste, improve the color fastness, and finally achieve the purpose of fabric printing. [0003] In order to ensure that the ink has high storage stability and long storage life, the traditional reactive inkjet ink uses a single chloro-s-triazine type reactive dye with low activity as the colorant. Due to the low reactivity of chloro-s-triazine reactive dyes, the color fixati...
