1. Used for dyeing and printing wool, silk and nylon, also used for dyeing paper, hemp, sisal and straw.

2. Wool dyeing should be carried out in an acetic acid bath or a neutral bath. The pH value is above 3.5, and the dye uptake rate is not high; the silk should be dyed in a weakly acidic bath, and the color fastness is 1 grade lower than that of wool dyeing; Performed in a weakly acidic bath.

3. Blending of blended products: When the wool is dyed in the same bath as the various fibers, the nylon is also dyed. The apparent color of the silk is lighter than that of the wool, and the cellulose fibers are slightly stained.

Packing:
