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 present invention proposes a soap-free reactive digital inkjet ink and its preparation method, and a soap-free printing and dyeing process of reactive inkjet printing applied to fabrics, which solves the problems of high ink prices and steaming in the existing reactive inkjet printing technology. Finally, soaping is required, and the process produces a large amount of printing and dyeing sewage. The non-soaping active digital inkjet ink contains the following raw materials in weight percentage: 9%-12% of reactive mixed dyes, 0.02%-0.04% of surfactants, 15%-30% of humectants, 0.05%-0.5% of fungicides, 0.03% to 2% of the pH regulator, 2% to 10% of the viscosity regulator, 0.01% to 0.05% of the defoamer, and the rest is deionized water. The problem of sewage discharge generated in the cleaning process such as soaping and water washing, and the problem of high cost of the existing active ink, so as to achieve the purpose of energy saving and emission reduction.

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...
