Fluorescent whitening agent BBU (4 sulfonic acid)

Optical Brightener BBU is an advanced optical brightener specially formulated for cellulosic fibers and polyester/cellulose blended fabrics. BBU has a blue-violet tone and can improve the whiteness and brightness of textiles at all stages of processing, from bleaching to finishing. This highly concentrated powder performs well in a variety of applications and is an essential ingredient for textile manufacturers seeking ideal results in whitening processes.

Main features and typical advantages :
1. High concentration powder: BBU is available in a highly concentrated powder form for easier handling and dosing during textile processing. The high concentration ensures manufacturers achieve the desired results with less product dosage, resulting in greater cost-effectiveness.
2. Medium affinity: This brightener has a moderate affinity for both cellulose fibers and polyester/cellulose blends. This property gives BBU the versatility to perform well on different textile substrates, providing consistent whitening results.
3. Good whitening effect: BBU is designed to effectively whiten during processing, ensuring textiles achieve high whiteness without the risk of fading. This good whitening effect helps improve the long-lasting brightness of the finished product.
4. Application stability: BBU has good stability in alkaline conditions, hydrogen peroxide, electrolytes and reducing agents. This stability ensures that the whitening effect is maintained throughout all processing stages, providing reliable performance even in challenging environments.

Product advantages:
1. Cost-effective solution: The low dosage requirements of optical brightener BBU provide manufacturers with a cost-effective solution. The product usage is small and the whiteness is high, thus reducing material costs and improving production efficiency.
2. No residue, suitable for continuous processing: The BBU is designed to have no tailing effects, making it ideal for continuous processing. Its good leveling properties ensure color and brightness consistency, especially in exhaust and whitewash processes.
3. Brightening effect: BBU provides high brightness in both continuous and exhaust applications. This high whiteness improves the beauty of textiles and meets the high standards of consumers in the market.
4. Wide range of uses: The optical brightener BBU can be used in a variety of bleaching processes, including semi-continuous and continuous bleaching with hydrogen peroxide. In addition, it is suitable for white discharge in printing pastes and effectively supports reductive intermittent bleaching.

Product features:
1. Appearance: BBU comes in the form of a yellow powder that is easy to handle and incorporate into textile processes. Its physical form facilitates storage and application in various processing systems.
2. Ionic properties: BBU is an anionic brightener that is compatible with a variety of other substances used in textile processing. Its anionic properties enhance its ability to effectively adhere to cellulosic and blended fibers.
3. UV absorption: The UV absorption range of BBU is between 465-485 nm. This absorptive property makes the fabric more reflective of UV rays, thereby enhancing the brightening effect and creating a visually appealing effect in a variety of lighting conditions.

Application areas:
Optical brightener BBU is suitable for various applications in the textile industry, especially in the whitening process of cellulosic fibers and polyester/cellulose blends.
1. Whitening in the bleaching process: BBU is ideally suited for use in hydrogen peroxide semi-continuous and continuous bleaching processes, effectively improving whiteness while maintaining fabric integrity.
2. Exhaust and water washing whitening process: The good leveling properties of BBU make it ideal for exhaust and wash whitening processes, ensuring consistent whiteness and uniformity in large batches of textiles.
3. White printing paste: BBU can be added to printing pastes to provide a brilliant white effect in printing applications. This versatility opens up creative design possibilities for textile production.
4. Reduce intermittent bleaching: This additive is also suitable for reductive intermittent bleaching, providing a flexible treatment method for a variety of fabrics.
