Silk, a soft, delicate fabric, needs special care. You need to be especially careful if you need to bleach it. For instance, chlorine bleach weakens or disintegrates certain fabrics. Here, you can try using hydrogen peroxide to remove color from your silk fabric.
Steps to Bleach Silk
- Place silk in a large enough pot, and enough water to cover the silk. Prepare a hot water at 140 degrees Fahrenheit.
- To bleach every pound of fabric, you should dissolve 1/2 teaspoon soda ash in the water. Then, put the fabric into the pot, and wash it in the hot water. Finally, rinse it thoroughly with water.
- Mix 7 1/2 tablespoons soda ash with 6 pints of 3-percent hydrogen peroxide in a stainless steel pot, and add 1 teaspoon of a professional textile detergent, which helps remove color and prepares fabric for dyeing.
- Heat the pot until it reaches 130F.
- Put the silk into the mixture, stir it with a wooden spoon which helps the peroxide reaches all the fabric. Submerge all silk for 24 hours.
- Rinse the fabric.
- Mix 11 tablespoons of white vinegar with 1 gallon of warm water. Put the silk in the mixture for 10 minutes, and stir it frequently.
Special textile detergents can be found at fabric, yarn and handicraft stores.
