Key Characteristics

Indigo Blue Vat Blue sublimes at temperatures between 390–392°C (734–738°F), making it suitable for high-temperature processing. Its insolubility in water and alcohol ensures stability during dyeing processes, while its solubility in organic solvents allows for efficient application. The dye’s ability to undergo chemical reduction and oxidation is critical for its use in vat dyeing, a technique that imparts deep, lasting color to fabrics.

Applications in the Textile Industry

Primarily used for dyeing cotton yarn, Indigo Blue Vat Blue is essential in the production of denim cloth for blue jeans. On average, a single pair of jeans requires 3–12 grams of this dye. Its versatility extends to wool and silk, where it delivers rich, consistent coloration. The dye’s compatibility with stone washing and acid washing processes allows for the creation of unique textures and finishes in denim.

According to NIST (National Institute of Standards and Technology), the textile industry relies on precise chemical standards to ensure product consistency and safety. Indigo Blue Vat Blue adheres to these standards, making it a trusted choice for manufacturers worldwide.
