Fluorescent Whitening Agent CPS-D is a specialized optical brightening agent formulated for textiles, particularly polyester and polyester blends. This agent provides exceptional whiteness and brightness with a distinct blue-violet shade, enhancing the aesthetic appeal of fabrics. Designed for use across a range of temperatures, from low to high, CPS-D delivers reliable results in various dyeing processes, making it an ideal choice for textile manufacturers aiming to achieve high-quality whiteness and brightness in their products.
Key Features and Typical Benefits
1. High Whiteness and Strong Fluorescence: CPS-D offers good whiteness, making fabrics look cleaner and more radiant.
2. Bluish-Violet Shade: The agent imparts a blue-violet undertone, which is effective at neutralizing any yellowish tints in the fabric.
3. Superior to Common Optical Brighteners: CPS-D outperforms standard optical brightening agents such as PS and DT. I
4. Temperature Adaptability: CPS-D is suitable for a range of temperatures, from low to high, making it adaptable to various textile dyeing processes.
5. Chemical Resistance: The brightening agent exhibits good stability in the presence of acids, alkalis, and hydrogen peroxide (H₂O₂).
Benefits
1. Economic Efficiency with Low Dosage: One of the key advantages of CPS-D is its low dosage requirement. Despite the minimal product usage, it delivers high levels of whiteness and brightness, contributing to cost savings while maintaining premium quality results.
2. Heat Stability: CPS-D is highly stable at both medium and high temperatures, which is crucial for maintaining fabric brightness during heat-intensive textile treatments.
3. Improved Fastness: CPS-D offers good fastness, meaning the brightening effect remains durable even after multiple washes and extended exposure to light and heat.
Properties
1. Physical Form: CPS-D is a liquid brightening agent, making it easy to handle and incorporate into textile dye baths.
2. Appearance: The product appears as a gray-blue dispersing liquid, which mixes uniformly with water and other textile treatment solutions.
3. Viscosity: CPS-D has a viscosity of less than 100 mPa.s at 25°C, ensuring smooth application without clogging or uneven dispersion during the dyeing process.
4. pH: The pH value of a 1% aqueous solution of CPS-D ranges between 6.0 and 8.0, allowing it to be compatible with other textile treatment chemicals and ensuring a stable brightening process.
5. Ionic Character: CPS-D is a non-ionic product, making it compatible with a wide range of other substances, including non-ionic, cationic, and anionic agents used in textile processing.
6. Flash Point: The flash point of CPS-D is above 93°C, which ensures safety and stability during textile production processes that involve elevated temperatures.
7. Density: The product has a density of 0.98-1.08 g/cm³ at 25°C, making it easy to dilute and measure accurately for consistent application.
8. Ultraviolet Absorption: CPS-D exhibits ultraviolet absorption in the range of 195-210 nm, enhancing its brightening effect by making the treated fabric more reflective under UV light.
Applications
Fluorescent Whitening Agent CPS-D is versatile and can be used in various textile whitening processes. It is particularly suited for polyester fabrics and polyester-blend materials, offering reliable performance in different dyeing equipment and at varying temperatures:
1. Polyester Fabrics: CPS-D is specifically designed for polyester textiles, providing outstanding whitening and brightening effects, even in fabrics with mixed fiber compositions such as polyester-cotton or polyester-linen blends.
2. Dyeing Machines: CPS-D is suitable for use in overflow dyeing machines, jig dyeing machines, and continuous padding equipment, ensuring consistent and even brightening across all types of dyeing setups.
3. Low to High-Temperature Dyeing: Whether the dyeing process is conducted at low, medium, or high temperatures, CPS-D delivers good brightening results, making it a flexible solution for a wide range of textile production environments.
