The silk is bleached before the coloring process in order to obtain pure white color. A small amount of bleaching powder and diluted acidic acid is mixed in cold water and the silk is washed in that solution. The washed silk is directly sent for coloring process.
The raw silk is directly dipped into the boiling colored solution for 5 minutes. Acidic acid is added to the solution as it helps to preserve the color permanently on the silk threads. After dyeing the silk is washed in normal cold water. At the end, the dyed silk is treated with finishing oil solution to get shine and luster. After the dyeing process the colored silk is dried in shades at room temperature.
