Product Description Product DescriptionChemical PropertiesChemical Formula: C29H22N5NAO7SMolecular Weight: 607.57Chemical Structure: Contains chromophores such as azo groups, with benzene rings connected by specific chemical bonds. This structure endows it with a red color and affinity for fibers.Stability: Relatively stable under normal storage and usage conditions. However, it should be kept away from strong oxidants, strong acids, and strong alkalis to prevent chemical reactions that may cause color changes or damage to the dye structure. Physical PropertiesAppearance: Usually a red powdery solid.Solubility: Soluble in water and alcohols. Its solubility in water increases with temperature, forming a stable aqueous solution, which is conducive to uniform dyeing during the dyeing process.Melting Point: >360°C Dyeing PropertiesDyeing Objects: Mainly used for dyeing cellulose fibers such as cotton, linen, and viscose. It can also be used for dyeing protein fibers like silk and wool, as well as synthetic fibers such as nylon, showing good affinity for various fiber materials.Dyeing Methods: Various methods such as dip dyeing and pad dyeing can be adopted. For dip dyeing, the fiber material is immersed in a dye bath containing Direct Red F2G. By controlling conditions such as temperature, time, and pH value, dye molecules are adsorbed and diffused into the fiber to achieve the dyeing effect. For pad dyeing, the fiber material is passed through padding equipment to evenly apply the dye liquor to the fiber surface, followed by post-treatment such as steaming or baking to fix the dye on the fiber.Shade and Strength: The shade is a bright red with high strength. A small amount of dye can achieve good dyeing depth, and it has good levelness, enabling the fiber material to obtain a uniform color.Light Fastness: Has good light fastness. Dyed fiber products are not easy to fade under daily light conditions, maintaining good color stability.Wash Fastness: Has a certain degree of wash fastness, but a small amount of dye may still fall off during washing. Therefore, when washing dyed fabrics, mild washing conditions should be preferred, avoiding the use of strong detergents and high-temperature washing.
