Chemical Dyes

Existing Chemical Dyes, contrary to aniline dyes, which have no stability, are permanent against light and washing and also are very economic.

For dyeing by this type of dye, temperature of dyeing bath must be lower than 55 to 60 degree C, as the bath liquid is acidic and higher temperature might effect on wool quality and make its color non-homogenous. To avoid un-level color of wool, an amount of sodium sulfate is added to bath.

Fore dyeing, at first particular dye is weighed proportional to pile weight, by scale or balance. Then 10% to 20% of sodium sulfate, 2% to 4% Sulfuric acid and 1/40 of water volume, proportional to wool weight, are prepared. Bath is completely mixed, so that dye spreads to the all points of mix.

Wool, which has been carefully washed, is entered to bath. It takes about 30 minutes to start boiling and it remains in bath for an hour in boiling condition. Then, it is carefully washed and dried.

Available powder dyes, kept in special jars in workshops, are: Red, dark blue, green, black, olive, pink, yellow and brown.
