In the competitive textile industry, achieving pristine whiteness and vibrant brightness in polyester fabrics is paramount. Manufacturers constantly seek cutting-edge solutions to elevate product quality and meet demanding aesthetic standards. NINGBO INNO PHARMCHEM CO.,LTD. offers a powerful answer: Optical Brightener ER-I (FBA199).


This advanced fluorescent whitening agent is specifically engineered for polyester fiber whitening, delivering an unparalleled high whitening brightening effect. Unlike conventional methods, ER-I ensures a pure, brilliant white finish that significantly enhances the visual appeal of polyester textiles and blends. Its unique formulation guarantees a reddish shade, which is highly sought after for a natural, clean white.


One of the most critical advantages of ER-I is its excellent fastness to sublimation. This property ensures that the whiteness achieved is not only intense but also highly durable, resisting discoloration and degradation even under high processing temperatures or prolonged exposure to light. This long-lasting performance is vital for fabrics that undergo rigorous finishing processes or are intended for outdoor use.
