The product is named High Quality Fluorescent Brightener 236 with the CAS number 3333 - 62 - 8. Fluorescent Brightener 236 is renowned for its high - quality performance and comes at the best price in the market. It belongs to the class of fluorescent whitening agents. These agents absorb ultraviolet light and re - emit it as blue - violet light, which can enhance the whiteness and brightness of materials.
Its chemical structure allows it to have excellent compatibility with a variety of polymers and substrates. Physically, it exists in a fine powder form, which makes it easy to handle and disperse in different systems. The purity of this high - quality product is typically above 99%, ensuring consistent and reliable performance in various applications.
High Quality Fluorescent Brightener 236 has a wide range of applications. In the textile industry, it is commonly used to brighten natural and synthetic fibers. When added to the dyeing or finishing process of cotton, polyester, nylon, etc., it can significantly improve the whiteness and brightness of the fabric, making the colors more vivid and attractive. This is especially important for white and light - colored textiles, as it can enhance their visual appeal and market competitiveness.
In the paper industry, it is used to improve the optical properties of paper. By adding this fluorescent brightener to the pulp or surface - coating process, the paper can achieve a higher level of whiteness, which is essential for high - quality printing papers, writing papers, and packaging papers. It can also reduce the amount of bleaching agents required, thus being more environmentally friendly.
Additionally, it is used in the plastics industry. In plastics such as polyethylene, polypropylene, and polystyrene, it can eliminate the yellowing caused by aging and improve the overall appearance of plastic products, making them look fresher and more appealing.
When using High Quality Fluorescent Brightener 236, it is crucial to follow proper procedures. For textile applications, it can be added to the dye bath or finishing solution. The recommended dosage usually ranges from 0.05% to 0.5% based on the weight of the fabric. First, dissolve the brightener in a small amount of warm water to form a homogeneous solution, and then add it slowly to the dye or finishing bath while stirring continuously to ensure even distribution.
In the paper industry, it can be added either to the pulp during the papermaking process or as a surface - coating agent. For pulp addition, the dosage is typically 0.02% - 0.2% of the pulp weight. When used as a surface - coating agent, prepare a coating solution with an appropriate concentration and apply it evenly on the paper surface using a coating machine.
In the plastics industry, it can be mixed with plastic resin granules before processing. The dosage is generally 0.01% - 0.1% of the resin weight. Use a high - speed mixer to ensure thorough mixing of the brightener and the resin, and then proceed with the normal plastic processing methods such as injection molding, extrusion, etc.
Case 1: A textile manufacturing company was producing white cotton T - shirts. They had been facing the problem of inconsistent whiteness and dull colors. After using High Quality Fluorescent Brightener 236 in their dyeing process with a dosage of 0.2% based on the fabric weight, the whiteness of the T - shirts increased significantly. The colors became more vivid, and the rejection rate due to poor appearance decreased from 10% to 2%. This led to a higher customer satisfaction rate and increased sales.
Case 2: A paper mill was producing high - quality printing paper. They wanted to improve the paper's optical properties without using excessive bleaching agents. By adding 0.05% of the fluorescent brightener to the pulp during the papermaking process, the paper achieved a higher level of whiteness compared to their previous products. The brightness and color fastness of the printed materials on this paper also improved, resulting in better - quality printed products and increased customer orders.
