Problems solved by technology

[0003] However, most of the inks used in digital inkjet printing are reactive inks, but the use of reactive inks has certain limitations. Reactive inks cannot be used for nylon, but for wool, cashmere and silk. The density and fluffiness after printing are far inferior to acid ink
However, commonly used acid inks are difficult to prepare high-concentration acid dye inks because the solubility of acid dyes is lower than that of reactive dyes, and the higher the concentration of acid dyes, the worse the stability of the ink. In addition, acid inks have poor versatility and fluency, so they cannot be used. For industrial nozzles, it cannot meet the needs of industrial production
The above problems have greatly hindered the popularization and application of head acid ink, and it is of great significance to develop an inkjet printing acid ink suitable for industrial nozzles.

Abstract

The invention discloses inkjet printing acidic ink suitable for industrial nozzles and a preparation method thereof. The ink comprises an acidic dye, a solubilizer, a surfactant, an organic solvent, a moisturizer, water and the like. The solubilizer is at least one selected from polyether polyol, caprolactam, and an ethylene oxide-epoxypropane copolymer; the surfactant includes at least two selected from EH-6, EH-9 and the like; the moisturizer is an amino acid moisturizer; and a defoamer is at least one selected from SUFYNOL DF-110D, BYK-094 and 104E. By means of the solubilizer, solubility of the acidic dye in the ink is effectively increased and flowability and jet-ability of the ink in an ink path and the nozzle are improved. The surfactant combination having low contact angle and low dynamic surface tension enables the ink to have better flatting and wetting properties. The combination of the solubilizer, the surfactant and the moisturizer enables the ink to have better universality and to be smoother, so that the ink is suitable for the industrial nozzles.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to an inkjet printing acid ink suitable for industrial nozzles and a preparation method thereof. Background technique [0002] Digital inkjet printing technology is a new textile printing technology. It uses special dye ink or pigment ink to print directly on textiles through inkjet printer. Compared with traditional printing technology, digital inkjet printing technology has the advantages of no need for plate making, saving dye Chemical materials, energy saving and water saving, short cycle, energy saving and emission reduction, rich colors, etc., are ecological and environmentally friendly clean production technologies, meeting the requirements of environmental protection, low carbon and sustainable development of the printing and dyeing industry. Now domestic textile printing enterprises are faced with the pressure of shortening delivery time, improving product quality, reducing inv...
