Sodium metabisulfite is a powerful reducing agent and antioxidant. The use of sodium metabisulfite in the tanning process helps to prevent oxidation of chrome tanned leathers and ensures a high quality end product.
Sodium metabisulfite removes excess chromium from the leather after the tanning process. This not only improves the quality and appearance of the leather, but also reduces the amount of chromium in the waste water, ensuring compliance with environmental regulations. It also helps to control pH levels at all stages of the leather processing, giving tanneries consistent results and improved efficiency.
In the textile industry, sodium metabisulfite is used as a bleaching agent to remove color impurities and improve fabric brightness.
In the textile industry, sodium metabisulfite is commonly used in dyeing, printing and finishing processes. It helps in fixing the dyes on the fabric and ensures vibrant and long lasting colors. It also helps to achieve uniform whiteness and prepares the fabric for further processing.
In printing, sodium metabisulfite is commonly used as a reducing agent to remove excess dyes and pigments from fabrics to ensure vibrant, long-lasting colors. It is also effective in neutralizing chlorine in water, making it an ideal dechlorinator for textile printing and dyeing processes.
Additionally, in dyeing applications, Sodium Metabisulfite is a powerful bleaching agent that changes the oxidation state of dyes to obtain the desired hue. This versatile compound helps maintain color consistency and improves overall dyeing efficiency.
