Cellulosic fibers, including cotton, viscose, and linen, are fundamental to the textile industry, valued for their natural feel and breathability. However, they often possess a yellowish tinge that diminishes their aesthetic appeal. To counter this, specialized cellulosic fiber brightening technology is essential. NINGBO INNO PHARMCHEM CO.,LTD. introduces Optical Brightener 4BK, a leading solution designed to impart exceptional whiteness and vibrancy to these natural materials.


Our Optical Brightener 4BK operates by converting invisible UV light into visible blue light, effectively masking yellow tones and enhancing the fabric's perceived brightness. This optical effect creates a brilliant white appearance that significantly improves the overall quality and marketability of cellulosic products. As a premier high whiteness agent for cellulosic fibers, it is meticulously formulated to ensure maximum efficacy without compromising fiber integrity.


The application of Optical Brightener 4BK is straightforward and highly efficient. The recommended textile whitening agent 4BK dosage ensures optimal results, allowing manufacturers to achieve desired whiteness levels with precision. Whether integrated into exhaust dyeing processes or continuous applications, its excellent solubility and high bath exhaustion contribute to reduced material consumption and processing time. This efficiency not only streamlines production but also aligns with sustainable manufacturing practices by minimizing waste.
