In the complex landscape of industrial textile manufacturing, achieving consistent quality and visual appeal requires versatile chemical agents. NINGBO INNO PHARMCHEM CO.,LTD. proudly presents Optical Brightener 4BK (FBA113), a critical component designed to optimize fabric whiteness and brightness at various stages, from pre-treatment to post-processing.


Optical Brightener 4BK functions effectively as a textile pre-treatment brightener. Applied early in the manufacturing chain, it prepares fibers and fabrics for subsequent dyeing and finishing, laying the foundation for a brilliant white base. This initial application helps to neutralize any inherent yellowness, ensuring that the final product achieves maximum luminosity and color vibrancy, especially for white or pastel shades.

Beyond pre-treatment, FBA113 is also an invaluable post-processing whitening agent. Once fabrics have undergone dyeing or other treatments, a final application of Optical Brightener 4BK enhances their visual appeal, correcting any dullness and imparting a fresh, crisp look. This dual functionality makes it an exceptionally cost-effective and efficient choice for textile factories aiming to streamline their operations while maintaining high-quality standards.
