I. Basic Information and Parameters

High Quality Fluorescent Brightener 135 is a premium - grade chemical product with CAS numbers 12224 - 12 - 3 and 1041 - 00 - 5. It is known for its excellent fluorescent properties and is offered at the best price in the market. This brightener typically comes in a fine - powdered form, which is easily soluble in certain organic solvents. The product has a high purity level, ensuring consistent and reliable performance in various applications. Its molecular structure is specifically designed to absorb ultraviolet light and re - emit it as visible blue light, effectively enhancing the whiteness and brightness of the treated materials.

II. Product Uses

1. Textile Industry: In the textile field, Fluorescent Brightener 135 is widely used to improve the appearance of natural and synthetic fibers. It can be added during the dyeing or finishing process to make fabrics look whiter, brighter, and more attractive. This is especially important for white or light - colored textiles, as it can enhance their visual appeal and marketability.

2. Paper Industry: For paper manufacturing, this brightener is an essential additive. It can be used in both coating and internal sizing processes. By adding it to the paper pulp or coating formulation, the brightness and whiteness of the paper can be significantly improved, making it suitable for high - quality printing, writing, and packaging applications.

3. Detergent Industry: Fluorescent Brightener 135 is also commonly used in laundry detergents. When added to detergents, it attaches to the fabric fibers during the washing process and imparts a bright, clean look to the clothes. It helps to counteract the yellowing that occurs over time, keeping the garments looking fresh and new.

III. How to Use

1. Textile Application: First, prepare a solution of the fluorescent brightener in an appropriate solvent according to the recommended concentration (usually ranging from 0.01% - 0.5% depending on the fabric type and desired effect). Then, add this solution to the dye bath or finishing bath during the textile processing. Ensure thorough mixing to achieve uniform distribution of the brightener on the fabric. After treatment, follow the normal rinsing and drying procedures.

2. Paper Application: For internal sizing, add the brightener to the paper pulp at the wet end of the paper - making process. The addition rate should be carefully controlled based on the paper grade and quality requirements. In the coating process, mix the brightener with the coating formulation evenly before applying it to the paper surface.

3. Detergent Application: Incorporate the fluorescent brightener into the detergent formulation during the manufacturing process. The recommended dosage is typically around 0.1% - 0.3% of the total detergent weight. Mix well to ensure a homogeneous distribution of the brightener in the detergent product.

IV. Detailed Usage Cases

1. Textile Case: A textile manufacturer was producing white cotton shirts. After adding Fluorescent Brightener 135 to the finishing bath at a concentration of 0.2%, the shirts showed a significant improvement in whiteness. The L* value (a measure of lightness in the CIELAB color space) increased from 90 to 95, making the shirts stand out on the market. Customers reported that the shirts looked cleaner and more vibrant, leading to an increase in sales.

2. Paper Case: A paper mill was manufacturing high - quality printing paper. By adding the brightener to the paper pulp at a rate of 0.05%, the brightness of the paper increased from 85% to 92%. The improved brightness enhanced the clarity of printed images and text, making the paper more suitable for high - end printing jobs. The mill received positive feedback from printing companies and was able to command a higher price for its paper.

3. Detergent Case: A detergent company incorporated Fluorescent Brightener 135 into its laundry detergent formula at a dosage of 0.2%. After conducting consumer trials, it was found that consumers noticed a significant difference in the brightness of their washed clothes. The clothes appeared whiter and brighter after just one wash, and the detergent gained a better reputation in the market, resulting in increased market share.
