In the complex landscape of industrial textile production, the finishing stage is critical for imparting desired properties and aesthetic appeal to fabrics. Among the myriad of finishing agents, those that enhance whiteness play a crucial role. NINGBO INNO PHARMCHEM CO.,LTD. highlights Optical Brightener 4BK as an indispensable industrial textile finishing agent, delivering exceptional whiteness and brilliance to a wide array of textile materials.


Optical Brightener 4BK functions as a fluorescent whitening agent, a class of compounds that absorb UV light and re-emit it as visible blue light. This unique property allows it to effectively mask any inherent yellowness in fabrics, making them appear significantly whiter and brighter. This is particularly beneficial for natural fibers like cotton, viscose, and linen, as well as synthetic blends like polyester-cotton, ensuring they meet the stringent whiteness standards expected in today's market.
