Embodiment 1

[0023] Preparation of reactive red ink:

[0024]

[0025] Add the above substances into the flask in turn, mix and stir evenly, and then filter them through 1.5 micron, 0.52 micron, and 0.2 micron filter membranes to remove impurities to prepare high-permeability inkjet printing reactive red ink.

[0026] The prepared ink was tested for printing fluency on the machine, and there was no disconnection and blockage within 24 hours, and the fluency was good. Use the prepared ink on silk fabric (100g / m 2 ) for inkjet printing (printing 5×5cm solid color blocks), steaming and fixing the color at 102°C for 20 minutes, washing in cold water, hot water, and cold water to test the color depth value of the printed fabric (K / S color measuring instrument, fabric Folding double layer), printing front K / S value: 13.6, reverse K / S value: 12.9, permeability 94.85% (permeability = fabric reverse K / S value / fabric front K / S value), strength loss rate 2%, the penetration effect is good, and t...

Embodiment 2

[0029] Preparation of reactive blue ink:

[0030]

[0031] Add the above substances into the flask in turn, mix and stir evenly, and then filter them through 1.5 micron, 0.52 micron, and 0.2 micron filter membranes to remove impurities to prepare high-permeability inkjet printing reactive blue ink.

[0032] The prepared ink was tested for printing fluency on the machine, and there was no disconnection and blockage within 24 hours, and the fluency was good. Use the prepared ink on silk fabric (100g / m 2 ) for inkjet printing (printing 5×5cm solid color blocks), steaming and fixing the color at 102°C for 20 minutes, washing in cold water, hot water, and cold water to test the color depth value of the printed fabric (K / S color measuring instrument, fabric Folding double layer), printing front K / S value: 12.2, reverse K / S value 11.7, permeability 95.90% (permeability = fabric reverse K / S value / fabric front K / S value), strength loss rate 2 % The penetration effect is good, and ...

Abstract

The present invention discloses a preparation method of ink jet printing high permeable reactive dye ink, and belongs to the technical field of fine chemical industry. The preparation method comprises: sequentially adding 1-10% by mass of reactive dye, 30-50% by mass of a moisturizer, 0.1-2% by mass of a surfactant, 5-10% by mass of an efficient permeable agent, 0.1-4% by mass of a pH value buffer agent, 5-15% by mass of urea, 0.1-2% of by mass of a metal complexing agent, 0.1-2% by mass of an anti-foaming agent, 0.1-2% by mass of fungicide, and the balance of deionized water to a flask, mixing, uniformly stirring, and carrying out filtration and impurity removing sequentially with filtration membranes with pore sizes of 1.5 [mu]m, 0.52 [mu]m, and 0.2 [mu]m to prepare the ink jet printing high permeable reactive dye ink. According to the present invention, the method is simple, and is suitable for batch production, and the developed ink jet printing high permeable reactive dye ink has characteristics of good printing smoothness, low dye hydrolysis degree, and double printing color depth improving.

Description

technical field [0001] The invention relates to a preparation method of ink-jet printing high-permeability reactive dye ink, which belongs to the technical field of fine chemicals. Background technique [0002] With the development of my country's economy and the improvement of people's living standards, major changes have taken place in the consumption concept of the textile market, and people's consumption demand for "personalized, multi-variety, short-cycle, cultural creativity and environmental protection" textiles is increasing day by day. Digital inkjet printing abandons the complex plate-making process of traditional printing. In addition to meeting the market's demand for small batches of printing, multi-color and personalized printing, its equipment occupies a small area, and the printing process saves dyes and chemicals compared with traditional printing. It is an ecological and environmentally friendly clean production technology that can meet the requirements of ...
