For textile manufacturers aiming for peak whiteness and brightness, understanding the precise application of fluorescent whitening agents is critical. Optical Brightener Agent CXT, supplied by NINGBO INNO PHARMCHEM CO.,LTD., offers remarkable results when applied correctly. This article delves into the technical aspects of its usage, covering various application processes and recommended parameters.

Optical Brightener Agent CXT is a versatile fluorescent whitening agent that can be integrated into several textile processing methods. Its ability to absorb UV light and re-emit it as visible blue light makes it ideal for achieving a high level of whiteness on cellulosic fibers, polyamide, and their blends. The agent is known for its good solubility in water, although it may form a suspension when prepared as a concentrated liquid, which does not impede its effectiveness.

One of the primary methods of application is the standard cotton whitening exhaust process. Here, the Optical Brightener Agent CXT is typically added to the dye bath. Recommended dosages range from 0.2% to 0.6% on the weight of the fabric (o.w.f.). The process is usually carried out at temperatures between 80-100°C for 20-30 minutes, with a liquor ratio of 1:10 to 1:20. The inclusion of a sulfate agent, such as 5-10g/L, can further optimize the process. This method ensures even distribution and effective whitening of the fabric.

Another important application is in conjunction with peroxide bleaching for cotton, also via an exhaust process. In this scenario, Optical Brightener Agent CXT is added alongside peroxide and stabilizers. Typical dosages for the brightener remain between 0.2% to 0.6% o.w.f. The process involves higher temperatures and longer times, around 100°C for 30-45 minutes, with a liquor ratio of 1:10 to 1:20. The presence of agents like sodium silicate and detergent further aids in achieving optimal bleaching and whitening.

For continuous processes, such as padding, Optical Brightener Agent CXT can be applied by impregnating the fabric with a solution containing 1-4g/L of the brightener. The liquor pick-up is typically controlled at 70-80%. The fabric is then subjected to heat treatment, usually below 160°C for 20-30 seconds. This method is efficient for large-scale production and ensures consistent application across the fabric width.
