Sodium bicarbonate (NaHCO₃), commonly known as baking soda, is a mild alkaline compound widely used in various industries, including textiles, food, and pharmaceuticals. In the textile industry, its primary functions include:
Dye Fixation: Sodium bicarbonate is used as a buffer to maintain the pH in dyeing processes, especially with reactive dyes. It helps ensure that the dye properly bonds with the fabric, particularly cotton, improving color fastness.
Neutralizing Agent: After processes involving acidic chemicals, sodium bicarbonate is used to neutralize acids, ensuring fabrics are pH balanced and safe for further treatment or wearing.
Scouring: It can be used in scouring processes to clean fabrics, helping remove natural oils, waxes, and impurities without being too harsh on the fibers.
Sodium bicarbonate is a relatively safe and environmentally friendly chemical compared to stronger alkalis like caustic soda. It is also non-toxic and easy to handle, making it a versatile agent in various textile treatments.
