In the intricate world of textile manufacturing, the final appearance of fabrics is critical. Dyeing and finishing processes demand specialized chemical auxiliaries that not only improve color vibrancy but also enhance overall whiteness and brightness. NINGBO INNO PHARMCHEM CO.,LTD. is proud to present Optical Brightener ER-I (FBA199), a cornerstone specialty chemical auxiliary for dyeing & finishing operations.


Optical Brightener ER-I, identified by its CAS No. 13001-39-3, is a versatile textile auxiliary chemical that plays a pivotal role in achieving brilliant white effects and intensifying the perceived brightness of colored fabrics. As a fluorescent whitening agent, it is indispensable in various stages of textile processing, including pretreatment, printing, dyeing, and post-processing. Its ability to mask inherent yellowness and convert UV light into visible blue light results in a cleaner, brighter appearance for a wide range of textile materials, particularly polyester and its blends.


The unique properties of ER-I, such as its high whitening brightening effect and its compatibility with various dyeing baths, make it an efficient choice for textile professionals. Furthermore, its excellent fastness to sublimation ensures that the enhanced brightness is durable and withstands the rigors of subsequent processing and end-use.
