Frequently Asked Questions
It is primarily used as a dye for cotton yarn, specifically for the production of denim cloth used in blue jeans, where it enables professional effects like stone and acid washing.
It must be stored in a cool, dry, and ventilated warehouse below 25°C and 75% humidity, completely sealed to avoid moisture and oxidation from sunlight or air.
Yes, while its primary use is for cotton denim, smaller quantities are effectively used for dyeing wool and silk fabrics.
It is strictly prohibited to transport Indigo Blue with oxidants or edible chemicals. It must also be protected from rain, direct sunlight, and high-temperature sources.
Higher purity ensures that the dye is more soluble in the required agents and provides a more consistent, vivid dark blue shade without contaminating the fabric.
