Problems solved by technology

With the development of digital technology, using computers to precisely control the dyeing process can improve production efficiency and yield, reduce production costs, and minimize the pollution of wastewater. However, the current inkjet dyes have a large average particle size and a high salt content. High, low coloring rate and low fastness, can not fully meet the needs of inkjet printing

Embodiment 1

[0063] a. Chlorosulfonation reaction, ice out

[0064] Add 1,750 kg of chlorosulfonic acid to the enamel tank. Circulate cold water to lower the temperature, and control the temperature to 40-50°C. It takes 2 hours to add copper phthalocyanine. Adjust the temperature to 110°C, maintain the temperature at 110-115°C, and react for 4 hours. Adjust the temperature to 55°C, maintain the temperature at 55-60°C, and add 350 kg of thionyl chloride in 2 hours. Maintain the temperature at 55-60°C and react for 3 hours. Adjust the temperature to 90°C, maintain the temperature at 90-95°C, and react for 1 hour. Adjust the temperature to 105°C. Maintain the temperature at 110-115°C and react for 3 hours.

[0065] Adjust the temperature to 10-15°C, add the obtained chlorosulfonation feed liquid into the ice-out tank in a thin stream, and control the temperature. It took 2 hours to maintain the temperature at 0-10°C and stir for 1 hour. Add the deicing liquid into the solid-liquid separ...

Embodiment 2

[0086] a. Chlorosulfonation reaction, ice out

[0087] Add 1,750 kg of chlorosulfonic acid to the enamel tank. Circulate cold water to lower the temperature, and control the temperature to 40-50°C. It took 2 hours to add copper phthalocyanine. Adjust the temperature to 128°C, maintain the temperature at 128-130°C, and react for 4 hours. Adjust the temperature to 65°C, maintain the temperature at 65-70°C, and add 560 kg of thionyl chloride in 2 hours. Maintain the temperature at 65-70°C and react for 2 hours. Adjust the temperature to 90°C, maintain the temperature at 90-95°C, and react for 1 hour. Adjust the temperature to 105°C. Maintain the temperature at 105-110°C and react for 1 hour.

[0088] Adjust the temperature to 20-25°C, add the obtained chlorosulfonation feed liquid into the ice-out tank in a thin stream, and control the temperature. Over 2 hours, the chlorosulfonation feed solution was added. Maintain the temperature at -5~5°C and stir for 1 hour. Add the d...

Embodiment 3

[0111] a. Chlorosulfonation reaction, ice out

[0112] Add 1,750 kg of chlorosulfonic acid to the enamel tank. Circulate cold water to lower the temperature, and control the temperature to 40-50°C. It took 2 hours to add copper phthalocyanine. Adjust the temperature to 128°C, maintain the temperature at 128-130°C, and react for 4 hours. Adjust the temperature to 60°C, maintain the temperature at 60-65°C, and add 525 kg of thionyl chloride in 1.5 hours. Maintain the temperature at 60-65°C and react for 2 hours. Adjust the temperature to 90°C, maintain the temperature at 90-95°C, and react for 1 hour. Adjust the temperature to 100°C. Maintain the temperature at 100-105°C and react for 2 hours.

[0113] Adjust the temperature to 25-30°C, add the obtained chlorosulfonation feed liquid into the ice-out tank in a thin stream, and control the temperature. It took 2 hours to maintain the temperature at 0-5°C and stir for 1 hour. Add the deicing liquid into the solid-liquid separ...

Abstract

Disclosed are a turquoise blue dye and a preparation method and application thereof. The dye has the structure as the formula, wherein x+y=3.5. The turquoise blue dye is small in average particle diameter and low in salt content, is gorgeous in luster, high in dyeing degree, stale and fine in repeatability during dyeing and is particularly applicable to ink jet printing and dyeing, excellent in application performance and convenient in use. Meanwhile, pollution to the environment can be reduced and required raw materials are low in cost by the aid of the preparation method and application of the turquoise blue dye.

Description

technical field [0001] The invention relates to a reactive dye and its preparation method and application, in particular to a turquoise blue reactive dye, its preparation method and its application in ink-jet printing. Background technique [0002] Inkjet printing technology is one of the main areas. There are two main types of this technology: continuous inkjet and drop-on-demand. These two printing technologies have special requirements for the dyes or organic pigments in the ink, such as the chemical structure of the dye, the average particle size, the conductivity of the aqueous solution, the pH value of the dye, the purity of the dye, especially the content of inorganic salts, etc. With the development of digital technology, using computers to precisely control the dyeing process can improve production efficiency and yield, reduce production costs, and minimize the pollution of wastewater. However, the current inkjet dyes have a large average particle size and a high sa...
