Key Characteristics

Indigo Blue Vat Blue exhibits remarkable chemical stability. It is insoluble in water, alcohol, and ether but dissolves in organic solvents like DMSO, chloroform, and concentrated sulfuric acid. Its sublimation point ranges between 390–392°C (734–738°F), making it suitable for high-temperature industrial processes. These properties ensure its effectiveness in dyeing applications while maintaining safety during handling and storage.

Applications in Textile Industry

The primary use of Indigo Blue Vat Blue lies in the textile sector, particularly for light indigo color manufacturers producing denim fabric. A single pair of blue jeans typically requires 3–12 grams of dye, highlighting its efficiency. Beyond denim, it is also used for dyeing wool and silk, offering a vibrant blue tone that resists fading. The dye's compatibility with stone washing and acid washing processes allows for the creation of unique textures and finishes in denim production.

Packaging and Logistics

Indigo Blue Vat Blue is available in various packaging options to suit different transportation and storage needs:

• 20kg cartons: 9 metric tons (no pallet) in a 20'GP container111; 18 tons (with pallet) in a 40'HQ container111
• 25kg bags: 12 metric tons in a 20'GP container111; 25 metric tons in a 40'HQ container111
• 500–550kg bags: 20–22 metric tons in a 40'HQ container111

Proper packaging ensures the product's stability during transit. Light indigo color suppliers emphasize the importance of avoiding mixing with oxidants or edible chemicals to prevent contamination. The dye must be protected from sunlight, rain, and high temperatures during transportation, with storage away from fire sources and heat.

Storage Guidelines

1. Store in a cool, ventilated, and dry warehouse. Maintain a temperature below 25°C and relative humidity below 75%.
2. Seal packaging tightly during the rainy season to prevent moisture ingress. Avoid prolonged exposure to sunlight or air to prevent oxidation.
3. Isolate from acids, alkalis, strong oxidants, and reducing agents to avoid deterioration or combustion.

These guidelines align with NIST standards for chemical storage, ensuring safety and product longevity. NIST's role in establishing measurement and testing protocols for industrial materials underscores the importance of adhering to such specifications.
