As a dedicated manufacturer and supplier of textile auxiliaries in China, we are committed to providing our clients with the knowledge to effectively utilize our products. This guide offers insights into the optimal usage of Optical Brightener BAC-L to maximize textile brilliance.

Optical Brightener BAC-L is a cationic fluorescent agent that functions by absorbing UV light and re-emitting it as visible blue light, thereby enhancing perceived whiteness. Its application as a dyeing auxiliary and textile printing auxiliary is widespread, contributing significantly to the aesthetic quality of finished fabrics. For purchasing managers, understanding the precise application parameters is key to successful integration into production processes. When you buy this product, it’s important to have clear usage guidelines.

The effectiveness of Optical Brightener BAC-L is highly dependent on correct dosage and application conditions. Typical usage involves a dosage range of 0.2% to 1.5%, calculated based on the weight of the material. The dyeing liquor pH is crucial; for Process A, it is typically adjusted to a slightly acidic range of 3-4 using agents like oxalic acid dihydrate. The material-to-liquor ratio, usually between 1:10 and 1:40, and temperature (90-98°C) for a duration of 40-60 minutes are also critical for achieving uniform and intense whitening. Process B offers an alternative involving sodium chlorite, with similar temperature and time parameters.

These detailed application methods ensure that R&D scientists and production teams can achieve consistent results and optimize their processes. The stability of BAC-L under these conditions, especially its resistance to chlorite bleach, makes it a reliable choice for demanding textile manufacturing environments.
