OB masterbatch can be used in a wide range of textile products, including apparel, bed linens, towels, and other home textiles, as well as in industrial applications like non-woven fabrics, automotive textiles, and technical textiles.

OB masterbatch is typically added to the polymer or resin used to produce textile fibers or fabrics. During the extrusion or spinning process, the masterbatch is mixed with the polymer, and the resulting fibers or fabrics exhibit the desired optical brightening effect.
