Achieving a dazzling, long-lasting white finish on natural and synthetic fibers like cotton and polyamide is a cornerstone of quality textile production. While both materials present unique challenges, the demand for brilliant whiteness remains universal. NINGBO INNO PHARMCHEM CO.,LTD. offers specialized optical brightener solutions designed to meet and exceed these expectations, ensuring stunning visual appeal and enduring quality for your cotton and polyamide fabrics.


Our advanced optical brightener, an off-white liquid formulated from stilbene derivatives, is expertly crafted to impart a superior neutral white shade. This anionic stilbene optical brightener works effectively on a wide array of textile types, including cellulosic fibers such as cotton, as well as polyamide and various blends. It transforms the intrinsic yellowish tint often found in these fibers into a vibrant, brilliant white, enhancing the overall aesthetic of the textile product. Its versatility makes it an ideal textile optical brightener for cellulosic blends and pure polyamide applications.


A critical attribute of this brightener is its excellent washfastness. This ensures that the pristine white finish achieved is not merely superficial but profoundly durable, resisting degradation even after repeated washing cycles. For consumers, this translates to garments and textiles that retain their fresh, bright appearance over time, adding significant value to your products. For manufacturers, a high washfastness polyester brightener (and similar performance on cotton/polyamide) reduces customer complaints and enhances brand reputation.


Furthermore, our optical brightener is highly effective for exhaust processes, which are commonly used for cotton and polyamide. Its very high bath exhaustion rate means that the brightening agent is efficiently absorbed by the fibers, leading to less wastage and improved economic viability. This efficiency also contributes to more sustainable production practices, aligning with modern industry demands for reduced environmental impact. The excellent stability of the product to alkalis, peroxide, and electrolytes ensures consistent performance, whether you are conducting normal cotton whitening exhaust process or integrating it into other finishing steps.
