For textile applications, the recommended dosage is usually in the range of 0.05% - 0.3% based on the weight of the fabric. First, dissolve the brightener in a suitable solvent or water to form a homogeneous solution. Then, add this solution to the dyeing or finishing bath during the appropriate stage of the textile production process. Stir well to ensure uniform distribution on the fabric.
In the paper industry, it is typically added to the pulp slurry at a dosage of 0.1% - 0.5%. The brightener can be added directly to the pulp mixer and thoroughly mixed to achieve the best brightening effect.
When used in detergents, it is usually added at a concentration of 0.01% - 0.1%. It can be mixed with other detergent ingredients during the manufacturing process to ensure even distribution in the final product.

After using our Fluorescent Brightener KS - N at a dosage of 0.2% in the fabric finishing process, the brightness and whiteness of the fabric increased significantly. The manufacturer received more orders from customers who were satisfied with the improved quality of the products.
