For textile manufacturers aiming to achieve superior brightness and a pristine white finish on polyester fabrics, understanding the role of optical brightening agents (OBAs) is crucial. Among these, Optical Brightener ER-330 stands out as a highly effective nonionic stilbene derivative. This article delves into its properties, applications, and why it's a preferred choice for businesses looking to buy high-quality textile auxiliaries from China.

Optical Brightener ER-330 is formulated to impart strong fluorescence and a high degree of whiteness to polyester fibers and their blends. Its chemical composition, 1,4-Bis(2-cyanostyryl)benzene, with C.I. Number 199 and CAS 13001-39-3, is specifically designed to absorb UV light and re-emit it in the blue region of the visible spectrum, making fabrics appear brighter and whiter.

One of the key advantages of ER-330 is its excellent fastness properties. This includes superior resistance to sublimation, light, and washing, ensuring that the enhanced whiteness and brightness are long-lasting. This makes it an indispensable component in textile dyeing and finishing processes where durability is paramount. For businesses seeking a reliable supplier, purchasing this specific optical brightener ER-330 ensures consistent performance.

The application of ER-330 is versatile, primarily used in padding and dipping processes. In padding applications, a dosage of 3-6 g/l is typically recommended, followed by drying and stenter fixation at 170-190℃ for 30-60 seconds. For dipping processes, a dosage of 0.3-0.6% (o.w.f.) with a liquor ratio of 1:10-30 is advised, with optimum temperatures between 100-125℃ for 30-60 minutes. These guidelines help users achieve the best possible results. If you are looking to purchase this chemical, understanding these usage parameters is key to effective application.
