The textile industry relies on a variety of chemical agents to transform raw fibers into finished fabrics. Among these, sodium bisulfite (CAS 7631-90-5) holds a significant position, primarily for its effective bleaching properties. NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier of premium sodium bisulfite, empowering textile manufacturers to achieve superior bleaching results and enhance fabric quality.

Sodium bisulfite acts as a reducing bleach, which is particularly advantageous for natural fibers like cotton. Unlike oxidizing bleaches that can sometimes damage delicate fibers, reducing bleaches work by chemically altering the chromophores – the color-bearing parts of the molecule – rendering them colorless. This process is gentler on the fabric, helping to maintain its strength and integrity while achieving a high degree of whiteness. The precise control offered by sodium bisulfite makes it a preferred choice for many cotton fabric bleaching operations.

The process of bleaching cotton fabric with sodium bisulfite typically involves immersing the fabric in an aqueous solution of the chemical under controlled temperature and pH conditions. The concentration of sodium bisulfite and the duration of the treatment are carefully managed to achieve the desired level of whiteness without over-processing the material. After the bleaching step, the fabric is thoroughly rinsed to remove any residual chemicals. Manufacturers seeking to buy sodium bisulfite for their textile bleaching needs must ensure they source a product that is consistent in its chemical composition and free from impurities that could affect the outcome.

NINGBO INNO PHARMCHEM CO.,LTD. understands the critical nature of chemical inputs in textile manufacturing. Our sodium bisulfite is produced with stringent quality control measures, ensuring high purity and consistent performance.
