Nylon and spandex fabrics are prized for their elasticity, durability, and smooth texture, making them staples in activewear, intimate apparel, and many other applications. However, these synthetic fibers are particularly susceptible to yellowing and oxidative degradation during processing and storage. To maintain their pristine appearance and functional integrity, specialized fabric protection technologies are indispensable.


NINGBO INNO PHARMCHEM CO.,LTD. addresses this critical challenge with its innovative 43520H High Concentration Anti-Yellowing and Anti-Oxidation Finishing Agent. This advanced chemical auxiliary is specifically engineered to counteract the primary causes of yellowing in nylon and spandex. During processes like heat setting and heat press molding, the high temperatures can trigger severe yellowing. Our heat setting yellowing prevention nylon solution, 43520H, forms a protective shield, preventing these undesirable reactions.


The efficacy of 43520H lies in its unique composition as a weak reductant, which preferentially reacts with environmental oxidants before they can damage the sensitive polyamide and polyurethane fibers. This proactive mechanism ensures that fabrics retain their original white or light coloration, avoiding costly quality issues and consumer complaints.


As a leading fabric anti yellowing additive for polyamide, 43520H is a crucial component for manufacturers aiming for excellence. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing high-performance solutions that contribute to the longevity and aesthetic appeal of textiles. By integrating 43520H into your production line, you can significantly enhance the value and marketability of your nylon and spandex products, ensuring they meet the highest standards of quality and appearance.
