Fluorescent whitening agent MST-G

Optical brightener MST-G is an optical brightener specially customized for cellulose fibers. It is particularly effective in the whitening process of cotton and its blended fabrics. MST-G's proven properties make it an essential ingredient for textile manufacturers to improve fabric brightness and whiteness.

Main features:
High Whiteness and Acid Resistance: MST-G provides high whiteness while maintaining resistance to acidic environments, making it ideal for a variety of textile applications. Its effectiveness over a wide pH range ensures that it can be used in different processing environments without loss of performance.

Product advantages:
1. Good water solubility: One of the outstanding features of optical brightener MST-G is its good water solubility. It dissolves easily in water, making it easy to use and suitable for different textile treatment processes. This feature simplifies the formulation and application of whiteners, allowing for consistent results.
2. Pure and bright color, low yellowness: MST-G has good whiteness and pure and bright color. After high-temperature curing, the yellowing of the product is low, ensuring that the whitening effect is consistent with the intended appearance. This property is crucial to maintaining the beauty of the finished fabric.
3. Low affinity: The low affinity of MST-G makes it particularly suitable for continuous pad dyeing processes. It reduces the risk of head-to-tail color differences in treated fabrics and ensures consistent brightness and color distribution. This feature is critical for mass production, which requires high consistency and quality.
4. Good acid resistance and hard water resistance: MST-G performs well in a variety of conditions, with reliable acid and hard water resistance. It is stable over a pH range of 2 to 11, making it suitable for use in single-bath processes with certain resin surface treatments. This compatibility simplifies production workflows and enhances product versatility.

Product features:
1. Appearance: Fluorescent whitening agent MST-G appears as a yellow-brown to brown-red transparent liquid. This visual signature is common among many optical brighteners and indicates that it contains active ingredients that help enhance its whitening effect.
2. Ionic properties: The product is classified as an anionic agent, ensuring compatibility with a wide range of textile auxiliaries and processes. This compatibility is essential to achieve ideal results in different applications.
3. UV absorbency: MST-G has a UV absorbance of 85-95, which helps improve its effectiveness as an optical brightener. This property enhances the fabric's ability to reflect light, giving the fabric a brighter, more colorful appearance.

Product application:
Optical brightener MST-G is particularly suitable for the whitening process of cotton and its blended fabrics. It has a variety of uses, including:
1. Pad dyeing process: MST-G is designed for use in the pad-dyeing process, taking full advantage of its properties to enhance the brightness of fabrics. The low affinity for fibers ensures that the whitening effect is evenly distributed without color difference.
2. Continuous production: The product has good solubility and stability, making it ideal for continuous production methods, allowing manufacturers to maintain high efficiency while achieving reliable results.

Preparation method:
To use optical brightener MST-G, follow these steps:
1. Dilution: MST-G can be diluted with water in any ratio. This flexible dilution allows for customized applications based on specific fabric requirements and processing conditions.
2. Stir: Make sure to stir the solution evenly so that it becomes a homogeneous mixture. This step is crucial to ensure consistent results during application.
3. Application: Once the MST-G solution is formulated, it can be used in pad dyeing processes or other textile treatments depending on the desired effect.
