Frequently Asked Questions
Indigo Blue is primarily used as a dye for cotton yarn, specifically for the production of denim cloth for blue jeans. It is also used in smaller quantities for dyeing wool and silk.
Due to its specific chemical properties and binding characteristics with cotton, it allows for controlled removal of color, enabling the rapid application of stone and acid wash effects.
It must be stored in a cool, ventilated, and dry warehouse below 25°C with relative humidity under 75%, sealed to prevent oxidation from air and sunlight.
It must be isolated from acids, alkalis, strong oxidants (such as potassium nitrate or ammonium nitrate), and reducing agents to prevent combustion or deterioration.
It is insoluble in water, alcohol, and ether, but soluble in DMSO, chloroform, nitrobenzene, and concentrated sulfuric acid.
We offer 20kg cartons, 25kg bags, and 500-550kg bulk bags, with logistics options for both 20’GP and 40’HQ containers depending on pallet requirements.
