The corrosion-resistant finishing agent is a specialized textile auxiliary designed to protect fabrics and fibers from the damaging effects of metal ion contamination and environmental factors. It effectively prevents corrosion, yellowing, and strength loss caused by iron, copper, and other metal residues during textile processing and daily use. This finishing agent enhances fabric durability, maintains color brightness, and ensures long-term stability under varying storage and wearing conditions. Suitable for cotton, polyester, nylon, and blended fabrics, it is widely applied in dyeing, printing, and finishing processes. With strong chelating ability and excellent compatibility, it provides reliable protection for high-quality, long-lasting textiles.
