522 Sulphur Black BR 200% Application:

1. Sulfur Black is mainly used for dyeing cotton, linen, viscose and their blended fabrics.

2. Compared with dyeing black with direct dyes and reactive dyes, sulfur black has better dyeing uptake and leveling, better blackness and better washing fastness. It is suitable for dip dyeing, coil dyeing and pad dyeing.

3. The suitable dyeing temperature is 90-95°C and bath PH is 9.5-10. When dyeing black, the ratio of sulphur black and Sodium Sulphide is about (dye strength is 100-200%-Sodium Sulphide dosage is 1-2 times)

4. When dyeing, Sodium Sulphide should not be too little, so as to avoid uneven dyeing and red spots, and too much will affect the dyeing rate of dyes, dyeing and washing should be sufficient, otherwise floating color will make the blackness not black.

5. Blended fabrics dyed in two colous with sulfur black can not be used.
