Synthetic fibers, including acrylic and polyamide, form the backbone of countless textile applications due to their durability and versatility. However, achieving desired levels of whiteness and vibrancy can be challenging. Optical Brightener SWN C.I. 140 is a vital additive for these materials, offering a powerful solution. NINGBO INNO PHARMCHEM CO.,LTD. is a leading optical brightener for acrylic fiber manufacturer and a trusted supplier for the synthetic fiber industry.


Optical Brightener SWN, also referred to as C.I. 140, is a highly effective coumarin derivative designed to enhance the optical properties of synthetic fibers. It works by absorbing non-visible ultraviolet light and re-emitting it as visible blue light. This optical transformation effectively masks any inherent yellowing or dullness in the fibers, resulting in a noticeably brighter, crisper white appearance. This process is crucial for producing high-quality synthetic textiles that meet consumer expectations for visual appeal.


For acrylic fibers, the application of SWN C.I. 140 provides an outstanding level of brightness, ensuring that products like acrylic yarns and fabrics exhibit superior whiteness. Similarly, as a potent polyamide fiber brightener supplier, NINGBO INNO PHARMCHEM CO.,LTD. ensures that polyamide materials, often used in activewear and industrial textiles, benefit from enhanced luminosity and color vibrancy. The excellent solubility and compatibility of SWN C.I. 140 make it easy to incorporate into various fiber processing stages, ensuring uniform distribution and consistent results.
