The subtle nuances of color are critical in the textile industry. Achieving the perfect shade of white, often characterized by a cool, bluish-violet tone, is a common goal for manufacturers. Optical Brightening Agent BAC-H is specifically formulated to deliver this sought-after aesthetic, offering an effective solution for enhancing fabric appearance. This article explores the benefits and application of BAC-H, a key product from a dedicated Chinese manufacturer and supplier.

Optical Brightening Agent BAC-H is a high-performance chemical that functions by absorbing ultraviolet light and re-emitting it as visible blue-violet light. This process counteracts the natural yellowing that can occur in fibers, making them appear significantly whiter and brighter. The specific bluish-violet shade it imparts is highly desirable as it gives textiles a clean, sharp, and modern look, distinguishing them in the marketplace.

Primarily used for acrylic fibers and secondary acetate fabrics, BAC-H is a cationic optical brightener. This means it has a positive charge, which leads to excellent substantivity (affinity) for negatively charged fibers commonly found in acrylics. This strong affinity ensures that the brightener is effectively applied and retained, providing a lasting whitening effect. Its application is crucial in the finishing stages of textile production to achieve maximum visual impact.

The efficacy of Optical Brightening Agent BAC-H is further enhanced by its stability during common textile processing steps, including those involving chlorite bleaching. This stability is a critical factor for manufacturers, as it ensures that the brightening effect is achieved consistently and without degradation of the agent's performance. The recommended usage typically involves dosages between 0.2% and 1.5% (o.w.f.) in dye baths, with careful control of pH (3-4) and temperature (90-98°C) for optimal results.

For textile manufacturers looking to buy optical brightening agents that deliver specific color effects and reliable performance, BAC-H is an excellent choice. Partnering with a trusted Chinese supplier ensures not only access to this high-quality product but also competitive pricing and a stable supply chain. By incorporating Optical Brightening Agent BAC-H into your finishing processes, you can effectively achieve the desired bluish-violet white shade, enhancing the visual appeal and market value of your textile products.
