The global push towards sustainability has significantly increased the demand for recycled polyester textiles. However, working with recycled materials often presents unique challenges, particularly concerning color and whiteness. Recycled polyester, derived from sources like PET bottles, frequently exhibits a more pronounced yellowish or grayish tint compared to virgin fibers. This makes achieving a clean, vibrant white a significant hurdle for manufacturers. Fortunately, specialized solutions are available to overcome these limitations, enhancing brightness in recycled polyester textiles effectively.


Fluorescent whitening agents (FWAs) are optical brighteners that play a crucial role in improving the appearance of recycled textiles. While the provided article specifically details Fluorescent Whitening Agent 20106 for virgin polyester, the principles of optical brightening apply broadly to regenerated fibers. These agents absorb invisible UV light and re-emit it as visible blue light, which cancels out the yellowing, making the fabric appear whiter and brighter. For recycled polyester, a powerful fluorescent whitening agent for polyester is essential to neutralize the inherent discoloration.
