In the intricate world of textile manufacturing, the final appearance of fabrics hinges on a variety of chemical treatments. Among these, optical brighteners are critical for achieving that sought-after bright white or enhanced color vibrancy. Optical Brightener NFW, a highly effective stilbene derivative, has become a staple chemical auxiliary for many dye houses and finishing plants. For professionals in the textile industry, understanding the precise application methods is key to maximizing the benefits of this product. If you're looking to buy Optical Brightener NFW, a thorough grasp of its usage will ensure optimal results.

Optical Brightener NFW, supplied as a slight yellowish liquid, excels in delivering a superior whiteness-increasing power. Its high solubility in water makes it exceptionally versatile for various textile dyeing techniques. For the exhaust dyeing process, typically applied to cotton and nylon fabrics, the recommended dosage ranges from 0.5% to 1.5% based on the weight of the fabric (o.w.f.). This process is often conducted at room temperature and ensures an even distribution of the brightener, leading to a uniform enhancement of whiteness. As a leading chemical auxiliary manufacturer, we ensure our product is optimized for these applications.

The padding process offers another effective route for applying Optical Brightener NFW. In this method, fabric is passed through a solution containing the brightener, followed by squeezing to achieve the desired pick-up rate. For brightening cotton or synthetic blends, dosages typically range from 5 to 15 g/L. This is often combined with drying and stentering steps. The excellent washing fastness and minimal yellowing after high-temperature stentering are significant advantages that our clients consistently value.
