2. Wool dyeing: It should be carried out in a neutral bath with ammonium sulfate as a dyeing aid. The dyeing bath has a pH value of 6~8. When the dyeing temperature is 70 °C, it can also obtain a high dye uptake rate. It needs to be boiled. It can be colored with neutral dyes.

3. Silk dyeing: It should be carried out in a neutral or weakly acidic bath. The sun and soaping fastness are good, and it is an important dye for bright green fruit and green color.

4. Nylon dyeing: It should be carried out in a neutral or weakly acidic bath. The sun and soaping fastness are good, suitable for dyeing bright green.

5. The color of copper, iron and chromium ions is yellow when dyeing.

6. It is suitable for direct printing of wool, silk and nylon fabrics, and can be used as flower dyes for stannous chloride discharge printing.
