Problems solved by technology

[0003] However, at present, the ink used in digital inkjet printing can only be used for exclusive nozzles. Commonly used reactive inks are difficult to prepare high-concentration reactive dye inks due to the low solubility of reactive dyes. The performance is poor, and it can only be used for special nozzles. When used for other nozzles, there will be a large number of disconnection or nozzle clogging. This problem greatly hinders the popularization and application of inks.

Abstract

The invention discloses ink and a preparing method thereof. The ink is prepared from, by mass, 3-20 parts of reactive dye, 5-30 parts of organic solvent, 1-5 parts of humectant, 0.1-0.5 part of preservative, 0.2-3 parts of surface active agents, 0.1-1 part of a pH conditioning agent, 1-5 parts of solubilizer and 40-120 parts of deionized water; the solubilizer is at least one of polyether polyol, ethylene oxide and a propylene epoxide block copolymer, the surface active agents are at least two of EH-6, EH-9, EH-14, 420, 440, 465, 485, 104 E and EXP.4300, and the humectant is an amino acid humectant. As the amino acid humectant is added into the ink, the moisture state of a nozzle can be well kept; at least one of polyether polyol, ethylene oxide and the propylene epoxide block copolymer serves as the solubilizer, solubility of the reactive dye in an ink system can be effectively improved, mobility and an ejection property of the ink in an ink path and a spray head are improved, and the ink can have good universality and smooth performance.

Description

technical field [0001] The invention relates to ink, in particular to an ink 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 inventory cost and improving service. They must respond quickly to the changing...
