Achieving a uniform and brilliant white on blended fabrics, especially those combining cotton and polyester, can be a complex challenge for textile manufacturers. Different fiber types react uniquely to whitening agents, often resulting in inconsistent brightness or a dull appearance. NINGBO INNO PHARMCHEM CO.,LTD. offers Sylic® OBA 4BK, a specialized optical brightening agent for polyamide blends and cotton/polyester compositions, engineered to deliver exceptional and harmonious whiteness across mixed fiber substrates.


Sylic® OBA 4BK, a highly effective fluorescent whitening agent for cotton and polyester, addresses the specific needs of blended textiles. Its advanced stilbene derivative chemistry ensures optimal absorption and re-emission of blue light, creating a vivid, 'whiter-than-white' effect that is consistent across different fiber types within the blend. This precision is critical for high-quality finished products that meet consumer expectations for pristine whiteness. Our expertise as a textile optical brightener manufacturer ensures that Sylic® OBA 4BK offers superb performance.


The versatility of Sylic® OBA 4BK extends to its application methods. It can be seamlessly integrated into both exhaust and continuous processes, providing flexibility for various production setups.
