Key Features and Advantages

• High Color Fastness: Indigo Blue Vat Blue retains its vibrancy even after repeated washing, making it a preferred choice for denim and other durable textiles.
• Chemical Stability: Its resistance to oxidation and degradation ensures long-term performance in industrial settings.
• Wide Application Range: Beyond denim, it is used for dyeing wool, silk, and other natural fibers.
• Customizable Packaging: Flexible packaging options (20kg, 25kg, 500-550kg) cater to diverse shipping and storage needs.

Applications in the Textile Industry

Indigo Blue Vat Blue is primarily used for dyeing cotton yarn, particularly in the production of denim for blue jeans. A single pair of jeans typically requires 3–12 grams of dye, depending on the desired shade and wash effect. Its unique properties enable advanced techniques like stone washing and acid washing, which create the distinctive faded look of vintage denim.

Smaller quantities are also employed in dyeing wool and silk, where its deep blue tone adds a luxurious finish. The dye’s solubility in organic solvents allows for efficient application in industrial dyeing processes, reducing waste and improving cost-effectiveness.

Storage and Transportation Guidelines

Proper handling is critical to maintaining the quality of Indigo Blue Vat Blue:

1. Storage: Keep in a cool, ventilated, and dry warehouse with a temperature below 25°C and humidity below 75%. Seal packaging during the rainy season to prevent moisture exposure.
2. Transportation: Avoid mixing with oxidants or edible chemicals. Protect from sunlight, rain, and high temperatures during transit.
3. Isolation: Store away from acids, alkalis, strong oxidants, and reducing agents to prevent chemical reactions.

For bulk shipments, the product is available in 20'GP and 40'HQ container111s with capacities ranging from 9–25 metric tons, depending on packaging type. This ensures efficient logistics for global suppliers and manufacturers.
