This is an important and significant step in Mangalagiri saris production. First the yarn is boiled in a mixture of water, costic acid and soap at an accurate temperature for 3 to 4 hours and dried overnight. The dried yarns are taken for the coloring process. They are boiled in a mixture of Hydrosulphite, color, water and costic acid, which is mixed in a boiler. The most important aspect in this process is the mixing of colors, which will give unique and durable color to the fabric. The yarns are dipped in the required color and the worker goes on turning the yarn so that the color is evenly mixed in the yarn.
After coloring, the yarn is sent for washing. They are first washed in water with chemical (sodium, alam, costic acid and dharvakam) in it. These chemicals helps in sustaining the color and make the yarn look in rich color and shiny. They are again rinsed in plain water and kept for drying in the sun. Dhamyanti and Chilka Pacha color are dyed twice to get the luster’s rich color.
If the weather is normal then they, take half or one day to dry. If it is raining the fabric takes 2 to 3 days to dry as they will be dried in room temperature. The yarn is bundled and packed after drying and sent for the next process.
