Achieving pristine whiteness and vibrant colors in textiles is a perpetual challenge for manufacturers. The key to overcoming this often lies in the strategic use of advanced chemical auxiliaries. Among these, Fluorescent Brightener 140, also known as Optical Brightening Agent SWN, stands out as a superior solution for enhancing fabric aesthetics.


This powerful coumarin derivative functions by absorbing invisible ultraviolet light and re-emitting it as visible blue light, effectively neutralizing yellowish undertones in fabrics and making them appear brighter and whiter. For textile mills, understanding the nuances of such agents is critical. NINGBO INNO PHARMCHEM CO.,LTD. is a leading textile brightener manufacturer, offering high-purity Fluorescent Brightener 140 designed for exceptional performance.


One of the primary benefits of this agent is its versatility across various fiber types. It is particularly effective as a Fluorescent Brightener 140 for wool whitening, delivering a radiant, clean look without compromising fiber integrity. Similarly, its application as a Coumarin derivative whitening agent for silk ensures a luxurious, untarnished sheen that natural silk deserves. For synthetic fibers, such as polyamide and especially when used as an Optical Brightening Agent SWN for acrylic fiber, it significantly boosts brightness, making colors pop and whites appear crisp.
