Problems solved by technology

However, the existing inkjet printing technology also has the following disadvantages, which hinder its large-scale application in printing and dyeing enterprises
At present, most of the printing inks used in the domestic market are imported, and the price of the ink is high. After steaming, it still needs to be soaped, which produces a large amount of waste water like traditional printing.
In addition, the existing inkjet printing also needs to be pretreated with traditional seaweed pulp and other pastes, so it needs to be dried, steamed, soaped and other processes like traditional printing, and a large amount of printing and dyeing sewage will be generated just like the traditional process

Abstract

The invention provides a soaping-free active digital ink-jet ink and a preparation method thereof, and an active ink-jet printing soaping-free printing and dyeing process used for fabrics. In the existing active ink-jet printing technology, the price of the ink is high, the soaping is required after steaming, and the process can produce a large amount of printing and dyeing sewage. A purpose of the present invention is to solve the problems in the prior art. The soaping-free active digital ink-jet ink contains the following raw materials by weight: 5-20% of an active mixing dye, 0.01-2.0% of asurfactant, 15-30% of a moisturizing agent, 0.05-0.5% of a bactericide, 0.03-2% of a pH value adjuster, 2-10% of a viscosity modifier, 0.01-0.05% of a defoamer, and the balance of deionized water. According to the present invention, the problems of the sewage discharge generated during soaping, water washing and other washing processes after the ink-jet printing aging of the active ink-adapted fabric, and the high cost of the existing active ink are effectively solved so as to achieve the purposes of energy saving and emission reducing.

Description

technical field [0001] The invention relates to the field of printing and dyeing technology, in particular to a soap-free active digital inkjet ink and its preparation method, and a soap-free reactive inkjet printing applied to fabrics such as cotton, silk, cotton fiber, and nylon Printing and dyeing process. Background technique [0002] Inkjet printing is to input the image through digital technology into the computer, after the software is modified and arranged, the inkjet printing system is controlled by the special RIP software. Spray the ink directly on the cotton cloth to achieve the printing pattern required by the design. Compared with traditional printing, inkjet printing has the following advantages: 1) High-end printing quality, rich inkjet printing colors, natural transition, no limit on the number of sets can realistically restore the pattern; 2) Plateless printing: the image can be printed directly on the fabric, saving money. It saves a lot of space by elim...
