Bleaching with Sodium Hydrosulphite (hydros)

(a)The degummed silk is treated in a bath containing 4 g/L of sodium hydrosulphite at 50°C for 4–6 h.
(b)The material must be completely immersed and the bleaching liquid stirred sufficiently to ensure uniform distribution.
(c)Finally the material is washed thoroughly. The solution should be made up only when required as its reducing power deteriorates rapidly under storage.

5.5.1.2 Bleaching with sulphur dioxide

(a)Degummed silk goods are hung in a suitable chamber where they are exposed to sulphur dioxide gas or immersed in sodium bisulfite in water for 4–6 h.
(b)Approximately 5 kg of sulphur is required to bleach 100 kg of silk. This method of bleaching is not generally practised as it causes air pollution.

Molecular formula: Na2S2O4
Appearance: Sodium Hydrosulfite is also known as sodium dithionite, and is white crystalline powder or yellowish. It is soluble in sodium hydroxide solution and slightly soluble in ethanol.Powdered anhydrous sodium hydrosulfite with a small amount of water may ignite in air by the heat of decomposition.
