Problems solved by technology

[0003] Reactive dyes are water-soluble dyes, which are characterized by water-soluble groups and reactive groups. During the dyeing process, the active groups can be covalently bonded to the fibers, so they are prone to hydrolysis and alcoholysis in water, and cannot be stored for a long time. , thereby reducing the color fastness of textile printing, the ink is easy to decompose, and it is easy to block the nozzle
[0004] Chinese patent CN 100381634C discloses a kind of textile digital printing reactive dye inkjet ink and its production process, which includes reactive dyes, humectants, descaling agents, bactericides, pH regulators, penetrating agents, deionized water, but due to The textile digital printing reactive dye inkjet ink does not select the appropriate pH value range and dye composition, and its application in real silk, pure cotton, hemp, viscose fiber, especially the color strength, color fastness and color weight on wool fabric poor performance

Abstract

The invention discloses digital printing active dye jet ink, comprising the following ingredients in percentage by weight: 1.0-20% of active dye, 10-40% of viscosity regulator, 0.2-2% of surface tension regulator, 0.1-3.0% of pH value control agent, 0.3-1.5% of sterilizer and the balance of de-ionized water. The digital printing active dye jet ink provided by the invention is suitable for printing and dyeing textiles, such as real silk, pure cotton, numb, viscose and mixed fiber thereof, and especially has the advantages of better chromaticity, color fastness and color repeatability on wool textiles.

Description

technical field [0001] The invention relates to a digital printing reactive dye inkjet ink. Background technique [0002] In recent years, textile digital printing technology has become a high-quality, low-cost, and environmentally friendly textile printing production method due to its short production process, no need for plate making, novelty and convenience, high utilization rate of dyes, and no waste materials. The field of digital inkjet printing continues to expand, and the scale of industrialization continues to expand, showing a good prospect for industrialization. [0003] Reactive dyes are water-soluble dyes, which are characterized by water-soluble groups and reactive groups. During the dyeing process, the active groups can be covalently bonded to the fibers, so they are prone to hydrolysis and alcoholysis in water, and cannot be stored for a long time. , thereby reducing the color fastness of textile printing, the ink is easy to decompose, and it is easy to bloc...
