Natriumdithionit Instructions

Discolour fabrics with Sodium Dithionite / Sodium Hydrosulfite 

Decolourising powder (sodium dithionite):
3 - 5 grams per 100 grams fabric weight.
1kg fabric weight requires 30 - 50 grams of powder.

Amount of water:
As much water as needed to cover the garments with water.

Water temperature:
Initially 85ºC heat to 95ºC

• To remove colours from fabrics, add equal parts of Sodium Hydrosulfite with Soda (Sodium Carbonate) (1:1) on 3-5% of the dry weight of  the fabric.  
• Heat the liquid to 85°C, add the fabric and continue heating. Colour stripping works best with boiling liquid. 
• Keep the fabric in motion for 10 to 20 minutes or until the colour has come out as desired. Then wash with mild detergent in cold water. 
• Please note: not all dyes can be removed from fabrics. Results may vary. If possible, make a test first.

Sodium Dithionite (Sodium Hydrosulfite) for indigo and dyer's woad

2 parts of sodium hydrosulfite & 1 part of pre-reduced indigo dye & 4 parts of soda
(Use 4 liters of water per 20g of dye)

• To reduce the indigo dye you also need, in addition to soda, Sodium Dithionite / Sodium Hydrosulfite. This produces the famous indigo vat.  
• For dyeing with powdered (pre-reduced) indigo you need Sodium Dithionite as reactive agent. It is added during the dyeing process. 
• Sodium Dithionite is also used to revive the dye liquor. 
• You also need this chemical for dyeing with dyer's woad.  

You can find detailed instructions on how to dye indigo in the product description of indigo textile dye at www.patin-a.de.
