The dyeing bath is adjusted with ammonium sulfate to adjust the pH value, and the temperature is raised to 130 ° C under neutral conditions, or the body is boiled. After the dye is dyed with the disperse dye, the dye is continuously dyed for half an hour, so that the cellulose fiber is fully colored, and the dye is exhausted.

4. Direct fast blue can be used for direct printing of cotton or viscose fabric, and can also be used for other color printing.
