Achieving optimal whiteness in textiles and paper is a nuanced process that requires a deep understanding of the chemicals involved. Ningbo Inno Pharmchem Co.,Ltd. provides this comprehensive technical guide to OBA BBU 220, designed for professionals seeking to master the application of this highly effective Fluorescent Whitening Agent. Understanding its properties and nuances is crucial for maximizing performance and consistency in your production lines.


Sylic® Fluorescent Whitening Agent OBA BBU 220 is a tetrasulfonic acid type Styrylbenzene derivative, renowned for its ability to convert invisible UV light into visible blue light, thereby enhancing the perceived whiteness and brightness of materials. Key to its efficacy is its excellent solubility in warm water (100 g/l @60ºC), which ensures easy preparation and homogeneous dispersion in application baths. This characteristic is vital for achieving good dyeing uniformity and preventing uneven brightening in large-scale operations.


The chemical stability of OBA BBU 220 is another critical aspect. It demonstrates robust acid & alkali resistant properties, performing optimally within a pH range of 6-11. This wide pH tolerance makes it suitable for various stages of textile and paper processing where pH fluctuations might occur. Furthermore, its high light fastness ensures that the whitening effect is durable, resisting degradation upon exposure to light, which is a common challenge for optical brighteners. Understanding these inherent properties is fundamental for optimal dosage fluorescent brightener application.


Precise application is key to avoiding issues like the 'extinction phenomenon' where excessive dosage can paradoxically reduce whitening effectiveness. For textiles, OBA BBU 220 boasts a fast dyeing speed and good compatibility with most chemical agents used in dyeing and finishing, allowing for efficient one-bath dyeing processes. However, certain precautions are necessary. It should be used before cationic additives or alum during pulp whitening to prevent sedimentation. Also, water containing metal ions (Cu, Fe, Mn, Zn) can affect performance, necessitating the use of chelating agents if present. Additionally, avoiding prolonged sun exposure after dissolution is recommended.


Ningbo Inno Pharmchem Co.,Ltd. emphasizes that meticulous adherence to BBU 220 application guidelines will unlock the full potential of this advanced agent for textile whiteness and paper brightener applications.
