Exhaust dyeing is a widely adopted process in the textile industry, known for its flexibility and ability to achieve deep, uniform shades. However, when it comes to achieving optimal whiteness, the selection of the right optical brightening agent is crucial. Traditional brighteners may not always deliver the desired brilliance or efficiency within this specific dyeing method. NINGBO INNO PHARMCHEM CO.,LTD. provides advanced optical brighteners specifically designed to optimize exhaust dyeing processes, ensuring superior whiteness and efficiency for a wide range of textile fibers.


Our flagship optical brightener, an off-white liquid optical brightener for polyester EBF, is engineered for peak performance in exhaust applications. This brightener, based on stilbene derivatives, exhibits a remarkable affinity for cellulosic fibers, polyamide, and their blends, ensuring even and consistent absorption during the exhaust process. This high affinity translates directly into efficiency, reducing the amount of product needed and minimizing waste. For textile manufacturers, this means both cost savings and a reduced environmental footprint.


A core advantage of this advanced optical brightener is its very high bath exhaustion rate. This critical feature ensures that nearly all the brightening agent transfers from the liquor onto the fabric, leading to excellent efficiency and minimal chemical residue in the wastewater. This directly benefits companies looking to purchase optical brightener for exhaust process textiles that delivers maximum value. Furthermore, its excellent washfastness guarantees that the brilliant neutral white shade achieved remains vibrant and durable through subsequent washing and wear cycles. This quality is particularly important for consumers who expect long-lasting aesthetic appeal from their textile products.


The product's exceptional stability to alkalis, peroxide, and electrolytes makes it highly versatile and reliable within the demanding conditions of exhaust dyeing. It can be confidently used in combined processes, such as normal cotton whitening exhaust procedures and peroxide bleaching for cotton exhaust process, without fear of degradation or reduced efficacy. This robust chemical profile ensures consistent, high-quality results batch after batch. Its good water solubility also facilitates easy preparation and uniform dispersion in the dye bath, simplifying the application process for operators.
