In textile manufacturing, the finishing stage is critical for enhancing fabric aesthetics and durability. Achieving lasting whiteness and brightness requires highly effective chemical auxiliaries. NINGBO INNO PHARMCHEM CO.,LTD. introduces Fluorescent Brightener ER-I, a vital chemical auxiliary for durable textile finishing, especially designed to impart superior, long-lasting whiteness to polyester and its blended fabrics.
Fluorescent Brightener ER-I, known also as Fluorescent Whitening Agent 199, is a stilbene-type optical brightener. Its inherent properties include excellent light and heat resistance, making it ideal for processes that involve high temperatures. This ensures the brightened effect is not only immediate but also sustains through washing, exposure to sunlight, and general wear. NINGBO INNO PHARMCHEM CO.,LTD. provides this product with a purity exceeding 98%, guaranteeing a high-quality solution for demanding textile finishing requirements.
As a non-reactive agent with common textile chemicals such as reducing agents or hypochlorite compounds, ER-I simplifies complex finishing formulations. Its good compatibility allows for seamless integration into existing processes, contributing to an efficient workflow. Whether you're targeting polyester whitening or enhancing blended textiles, this agent provides high fluorescence intensity and effective whitening, ensuring a blue-violet light that gives fabrics a crisp, clean appearance.
