Achieving optimal whiteness in polyester fabrics is a nuanced process that extends beyond simple bleaching. Textile manufacturers constantly seek the most effective methods and chemicals to ensure their products boast a brilliant and appealing white. Optical brighteners are key to this, transforming the visual quality of polyester.


At NINGBO INNO PHARMCHEM CO.,LTD., we understand the intricacies involved in optimizing fabric whiteness techniques. Our Fluorescent Brightener ER-330 is a prime example of an advanced solution designed specifically for this purpose. This nonionic brightener, also known as C.I. 199, excels in imparting a strong, lasting fluorescence to polyester and its blends, making them appear significantly whiter and brighter.


The optical brightener selection for polyester is critical. ER-330 is chosen for its superior whitening performance and its excellent fastness to light, washing, and sublimation. This ensures that the achieved whiteness is not fleeting but endures through the lifecycle of the textile, maintaining consumer satisfaction. Its versatility in application methods, including pad-thermos fixing and HT exhausting, makes it adaptable to various production setups, ensuring seamless integration into existing processes.


For those looking to buy ER-330 brightener, NINGBO INNO PHARMCHEM CO.,LTD. provides a reliable source of this high-performance chemical. Proper application involves adjusting parameters such as pH (ideally 4-5 for pad-thermos and 5-7 for HT exhausting) and treatment temperature (180-200°C for pad-thermos, 120-130°C for HT exhausting) to maximize its effect. By meticulously controlling these factors and utilizing a high-quality optical brightener like ER-330, textile producers can consistently achieve superior fabric whiteness and brightness, setting a new standard for their products.
