A kind of reactive dye ink and preparation method thereof

Abstract

The invention discloses reactive dye ink which comprises the following components in percentage by mass: 3-12% of dye, 0.2-0.4% of pH regulator, 0.2-0.4% of sterilizing agent, 18-35% of surfactant, 5-8% of dodecyldimethyl betaine, 3-6% of tetrabromobisphenol A, and the balance of water. According to the reactive dye ink, the tension on the surface of the ink can be controlled by the surfactant so as to adapt to the requirement of a digital ink-jet printing machine, the surfactant can also play a role in helping dissolving the ink so as to increase the force distribution of the liquid dye; the sterilizing agent is used for preventing liquid from generating mildew and plugging an ink channel, the tetrabromobisphenol A and the dodecyldimethyl betaine form a layer of protective film structure for coating ink particles, so as to prevent the decoloration of printed products; certain fireproof and flame-retardant properties of the later printed products can be guaranteed; electrostatic generated in self textile can be prevented due to mutual friction, so that the phenomena that the strands of spinning silks are scattered and difficultly wound and filament burs and broken filament are caused can be avoided.

Description

Technical field [0001] The invention relates to a dye, in particular to a textile reactive dye ink. Background technique [0002] Material is one of the most important raw materials in the textile industry. Dyeing and printing of textiles are inseparable from dyes. Dye inks are molecular-level fully-dissolved inks, generally 1 to 2 nanometers in diameter. The probability of blocking the ink head is very small. It is easy to be absorbed by the material after printing, and it is printed on flat and smooth paper. It has a good light radiation performance. Therefore, the ability of color reproduction is relatively strong, the printed image is colorful, and the cost is low; but because the dye ink is not protected by a layer of polymer on the surface like the pigment ink, the molecules are easily decomposed under harsh conditions. Causes fading. Summary of the invention [0003] Objective of the invention: In order to overcome the shortcomings in the prior art, the present invention ...

Problems solved by technology

Dye ink is fully soluble ink at the molecular level. The general diameter is 1-2 nanometers. The probability of clogging the ink head is very small. Therefore, the ability of color reduction is relatively strong, and the printed image is bright in color, and the cost is low; but because the dye ink is not protected by a layer of polymer on the surface like pigment ink, the molecules are easy to decompose under harsh conditions. cause fading
