Embodiment 1

[0023]Preparation of active red ink:

[0024]

[0025]The above substance was sequentially added to the flask, mixed and stirred and uniform, and then used in sequentially filtered by 1.5 microns, 0.52 microns, 0.2 microns, and prepared high permeable ink printing active red ink.

[0026]The preparative ink is printed in the printing fluidity test, and there is no disconnection closure within 24 hours, and the fluency is good. Prepared ink to silk fabric (100 g / m2), Inkjet printing (printing 5 × 5 cm pure-color block), 102 ° C steamed solid color 20 minutes, cold water washing, hot water washing, cold water washing, test print fabric color deep value (K / S colorimeter, fabric Folding double layer), printed front K / S value: 13.6, reverse surface K / S value: 12.9, penetration is 94.85% (permeability = fabric reverse surface K / S value / fabric front K / S value), strong loss rate is 2%, good penetration, and negative printed effects can be achieved.

[0027]After testing the printing, the ...

Embodiment 2

[0029]Preparation of active blue ink:

[0030]

[0031]The above substance was added to the flask, mixed and stirred and uniform, then in turn by 1.5 microns, 0.52 microns, 0.2 microns filtration, and prepared high permeable ink printing active blue ink.

[0032]The preparative ink is printed in the printing fluidity test, and there is no disconnection closure within 24 hours, and the fluency is good. Prepared ink to silk fabric (100 g / m2), Inkjet printing (printing 5 × 5 cm pure-color block), 102 ° C steamed solid color 20 minutes, cold water washing, hot water washing, cold water washing, test print fabric color deep value (K / S colorimeter, fabric Folding double layer), print front K / S value: 12.2, reverse surface K / S value 11.7, penetration is 95.90% (permeability = fabric reverse surface K / S value / fabric front K / S), strong loss rate is 2 The% infiltration effect is good, and there is a good printing effect. After testing the printing, the water washed with the fabric was 4-...

Abstract

The invention discloses a method for preparing an ink-jet printing high-permeability reactive dye ink, which belongs to the technical field of fine chemicals. The present invention is 1%-10% active dye, 30%-50% moisturizing agent, 0.1%-2% surfactant, 5-10% high-efficiency penetrating agent, 0.1%-4% pH buffering agent, 5%-15% urea, 0.1%-2% metal complexing agent, 0.1%-2% defoamer, 0.1%-2% bactericide, and add deionized water to make up 100% of the rest in the flask in turn, Mix and stir evenly, and then filter and remove impurities through filter membranes of 1.5 micron, 0.52 micron and 0.2 micron in order to prepare high-permeability inkjet printing active ink. The method of the invention is simple, suitable for mass production, and the developed high-permeability inkjet printing active ink has good printing fluency, low dye hydrolysis degree, and improved double-sided printing color depth.

Description

Technical field[0001]The present invention relates to a method of preparing an inkjet printing hypermanective dye ink, belonging to the field of fine chemical technology.Background technique[0002]With the development of my country's economy, people's living standards have increased significant changes in the consumption concept of textile market, and people's consumption demand for "personalized, multi-variety, short cycle, cultural creativity" textile consumption is increasing. Digital inkjet printing abandoned the traditional printing complex platelet, in addition to the market to meet the market's small batch, multi-color and personalization, its equipment covers a small area, and the printing process is more saved in traditional printing. With water resources, it is an ecological environmentally friendly cleaning production technology that meets the requirements of environmentally-friendly low-carbon sustainable development in the printing and dyeing industry. It can be seen tha...
